  2. The circulation of Ghlin flint during the time of the Blicquy - Villeneuve-Saint-Germain culture (Early Neolithic

    Directory of Open Access Journals (Sweden)

    Full Text Available In the North of France and Belgium, the Blicquy - Villeneuve-Saint-Germain culture marks the end of the Early Neolithic Period (beginning of the 5th millennium. The Blicquy group is constituted of eleven sites located in Belgium, with two main centers of occupation: one Western in Hainaut and one Eastern in Hesbaye, 100 km away from the first. As part of a PhD, the lithic industry of these sites is studied in order to reconstruct the circulation networks through a techno-economic analysis. It has been complex to identify the raw materials, given the lack of information about the siliceous outcrops in the Mons Basin. However, two main circulation networks have been highlighted: one of Ghlin flint and one of tertiary Bartonian flint. These two types of flint are indeed easily recognizable by their macroscopic characteristics. The outcrops of tertiary Bartonian flints originate from the Paris Basin, where systematic surveys have been conducted since the late 1980s. The circulation of tertiary Bartonian flint is now well-known and emblematic of the Blicquy - Villeneuve-Saint-Germain culture. Therefore, this paper will focus on the circulation of Ghlin flint in the Blicquy-Villeneuve-Saint-Germain culture. The Ghlin flint shows on the surface in the Mons Basin, about twenty kilometers away from the Hainaut sites. Heavily exploited in the latter, it was exported to the Hesbaye sites in a significant way, despite the availability of siliceous resources available in Hesbaye. Moreover, some artifacts circulated towards the Paris Basin. The study of the circulation of Ghlin flint can therefore help to determine the socio-economic organization of these populations by specifying the linkages between the population centers of Hainaut, Hesbaye and Paris Basin.

  4. First record of Atherigona reversura Villeneuve (Diptera: Muscidae feeding on Bermudagrass (Cynodon dactylon cv. Jiggs, Poaceae in Brazil: morphological and molecular tools for identification

    Directory of Open Access Journals (Sweden)

    Leandro do Prado Ribeiro


    Full Text Available Bermudagrass (Cynodon dactylon cv. Jiggs is an important food source for dairy cattle in the semi-intensive milk production systems most often used in southern Brazil. Although many insect pests are associated with feed grasses, we report here the first occurrence of the fly Atherigona (Atherigona reversura Villeneuve, 1936 (Diptera: Muscidae feeding on bermudagrass in Brazil. This potential pest was observed in April 2015 in three localities (Abelardo Luz, Palmitos, and Videira in western Santa Catarina, in southern Brazil. The infested plants had senescent and necrotic terminal leaves that reduced plant growth. New growth had to sprout new tillers from basal nodes, which resulted in a reduced plant growth rate. We also provide a morphological identification key (with figures for A. (Atherigona reversura and A. (Acritochaeta orientalis Schiner, 1868. A molecular identification based on COI is also provided to better differentiate species. Keywords: COI gene, Insect pest, Pastures, Plant–insect interaction

  9. Annotated catalogue of the Tachinidae (Insecta, Diptera) of the Afrotropical Region, with the description of seven new genera (United States)

    O’Hara, James E.; Cerretti, Pierfilippo


    Abstract The Tachinidae of the Afrotropical Region are catalogued and seven genera and eight species are newly described. There are 237 genera and 1126 species recognized, of which 101 genera and 1043 species are endemic to the region. The catalogue is based on examination of the primary literature comprising about 525 references as well as numerous name-bearing types and other specimens housed in collections. Taxa are arranged hierarchically and alphabetically under the categories of subfamily, tribe, genus, subgenus (where recognized), species, and rarely subspecies. Nomenclatural information is provided for all genus-group and species-group names, including lists of synonyms (mostly restricted to Afrotropical taxa) and name-bearing type data. Species distributions are recorded by country within the Afrotropical Region and by larger geographical divisions outside the region. Additional information is given in the form of notes, numbering about 300 in the catalogue section. Seven genera and eight species are described as new: Afrophylax Cerretti & O’Hara with type species Sturmia aureiventris Villeneuve, 1910, gen. n. (Exoristinae, Eryciini); Austrosolieria Cerretti & O’Hara with type species Austrosolieria londti Cerretti & O’Hara, gen. n. and sp. n.

  15. Covert orienting in the split brain: Right hemisphere specialization for object-based attention. (United States)

    Kingstone, Alan


    The present paper takes as its starting point Phil Bryden's long-standing interest in human attention and the role it can play in laterality effects. Past split-brain research has suggested that object-based attention is lateralized to the left hemisphere [e.g., Egly, R., Rafal, R. D., Driver, J., & Starreveld, Y. (1994). Covert orienting in the split brain reveals hemispheric specialization for object-based attention. Psychological Science, 5(6), 380-382]. The task used to isolate object-based attention in that previous work, however, has been found wanting [Vecera, S. P. (1994). Grouped locations and object-based attention: Comment on Egly, Driver, and Rafal (1994). Journal of Experimental Psychology: General, 123(3), 316-320]; and indeed, subsequent research with healthy participants using a different task has suggested that object-based attention is lateralized to the opposite right hemisphere (RH) [Valsangkar-Smyth, M. A., Donovan, C. L., Sinnett, S., Dawson, M. R., & Kingstone, A. (2004). Hemispheric performance in object-based attention. Psychonomic Bulletin & Review, 11(1), 84-91]. The present study tested the same split-brain as Egly, Rafal, et al. (1994) but used the object-based attention task introduced by Valsangkar-Smyth et al. (2004). The results confirm that object-based attention is lateralized to the RH. They also suggest that subcortical interhemispheric competition may occur and be dominated by the RH.

    In this article, various cases in helping to restore works of art by stimulated infrared thermography are presented. First, the method allows detecting old restorations found on a mural painting in the French senate. Then, it is demonstrated how the photothermal method enables determination of the underlying structure of the mural painting "The Apotheosis of Saint Bruno" in the Charterhouse of Villeneuve-lez-Avignon. Finally, the method allows locating separate canvas paintings on "Avenant de l'aurore" in the "Luxembourg" French Senate building.

  5. Is it really necessary to outlaw prospecting for shale hydrocarbons in France?

    International Nuclear Information System (INIS)

    Leteurtrois, Jean-Pierre


    Gasland, a documentary by Josh Fox, an American film-maker, blames shale gas operations in the United States for all sorts of environmental sins. This caricature, talented but one-sided, has no scientific grounds. It has been a source of disinformation in France, where it has stoked public opinion to oppose extracting gas from shale. From Villeneuve-de-Berg in Ardeche through Larzac to Doue in Seine-et-Marne, thousands of persons have demonstrated against plans for prospecting for shale gas deposits. Fanned by the media and relayed by locally elected officials of all political suasions, this opposition resulted in three bills of law being introduced in parliament to forbid hydraulic fracturing, the only technique available at present for extracting hydrocarbons from shale. Emergency procedures for speeding up the legislative process led to a law being adopted on 13 July 2011

It studies some of the main actors who constructed Maurrassism, the stategies which allowed them to dominate French cultural life from the beginning of the 1920s to the end of World War II and their ideology. It shows how this ideology was disseminated in different fields, history, literature, music, etc. and how this plural approach contributed to the success of a movement whose aim was to disqualify the very idea of democracy.

    Full Text Available The history of the classification of the Tachinidae (Diptera is traced from Meigen to the present. The contributions of Robineau-Desvoidy, Townsend, Villeneuve, Mesnil, Herting, Wood and many others are discussed within a chronological, taxonomic, and geographic context. The gradual development of the Tachinidae into its modern concept as a family of the Oestroidea and the emergence of the classificatory scheme of tribes and subfamilies in use today are reviewed. Certain taxa that have in the past been difficult to place, or continue to be of uncertain affinity, are considered and some are given in a table to show their varied historical treatments. The more significant systematic works published on the Tachinidae in recent decades are enumerated chronologically.

  9. Shale gas, a hazardous exploitation

    International Nuclear Information System (INIS)

    Maincent, G.


    In march 2010 three authorizations to search for shale gases were delivered in France in the regions of Montelimar, Nant and Villeneuve-de-Berg. A general public outcry has led the government to freeze the projects till a complete assessment of the impact on the environment is made. The fears of the public are based on the feedback experience in the Usa where some underground waters were polluted. The source of pollution is twofold: first the additives used in the injected fluids (methanol as an anti-microbic agent, hydrochloric acid to dissolve natural cements or glycol ethylene as a deposit inhibitor) and secondly metal particles of copper, zinc or lead trapped in the clay layers and released by the injection of the fluids. It appears also that the injection of high pressure fluids near a crack can induce earth tremors by reactivating the crack. (A.C.)

    Full Text Available Lieu de villégiature cardinalice au temps de la papauté avignonnaise, Villeneuve-lès-Avignon conserve quelques vestiges des palais de plusieurs membres du Sacré Collège. Le palais de Thurroye est l'un d'eux, successivement habité par Bertrand de Deaux, Guy de Boulogne et Pierre de Thury, aujourd'hui très morcelé et profondément bouleversé. Le présent article propose une restitution de cette résidence à la lumière de descriptions anciennes d'autres palais semblables de la banlieue avignonnaise, à la lumière notamment de la relation toscane d'une fête donnée dans l'un des palais en 1353 en présence de Clément VI. L'analyse fait apparaître le schéma type de ces demeures avec leur cour et leur portique, leur distribution à double grand-salle etc.During the Avignon papacy, Villeneuve-lès-Avignon was a place of summer retreat for the cardinals. Today, the town still has some vestiges of the palaces of several members of the Holy College. The Thurroye palace is one of these, successively occupied by Bertrand de Deaux, Guy de Boulogne and Pierre de Thury. It is now considerably altered. The present article proposes a restitution of the residence, based on old descriptions of similar palaces in the region of Avignon and, in particular, on the Tuscan account of a fete given at one of these palaces in 1353, in the presence of Pope Clément VI. The analysis depicts a typical layout for these residences with a courtyard and a gateway and their interior distribution with two large chambers.

  11. Not all attention orienting is created equal: recognition memory is enhanced when attention orienting involves distractor suppression. (United States)

    Markant, Julie; Worden, Michael S; Amso, Dima


    Learning through visual exploration often requires orienting of attention to meaningful information in a cluttered world. Previous work has shown that attention modulates visual cortex activity, with enhanced activity for attended targets and suppressed activity for competing inputs, thus enhancing the visual experience. Here we examined the idea that learning may be engaged differentially with variations in attention orienting mechanisms that drive eye movements during visual search and exploration. We hypothesized that attention orienting mechanisms that engaged suppression of a previously attended location would boost memory encoding of the currently attended target objects to a greater extent than those that involve target enhancement alone. To test this hypothesis we capitalized on the classic spatial cueing task and the inhibition of return (IOR) mechanism (Posner, 1980; Posner, Rafal, & Choate, 1985) to demonstrate that object images encoded in the context of concurrent suppression at a previously attended location were encoded more effectively and remembered better than those encoded without concurrent suppression. Furthermore, fMRI analyses revealed that this memory benefit was driven by attention modulation of visual cortex activity, as increased suppression of the previously attended location in visual cortex during target object encoding predicted better subsequent recognition memory performance. These results suggest that not all attention orienting impacts learning and memory equally. Copyright © 2015 Elsevier Inc. All rights reserved.

While PIM is restricted to the peri-implant mucosa and is reversible, PI also affects implant-supporting bone and, therefore, is very difficult to eradicate. PIIDs in clinical outcome may resemble gingivitis and periodontitis, as they share similar risk factors. However, recent study in the field of proteomics and other molecular studies indicate that PIIDs exhibit significant differences when compared to periodontal diseases. This review aims to elucidate the current knowledge of PIIDs, their etiopathology and diversified microbiology as well as the role of molecular studies, which may be a key to personalized diagnostic and treatment protocols of peri-implant infections in the near future.

  13. SAT's infrared equipment using second-generation detectors (United States)

    Siriex, Michel B.


    In 1982 SAT proposed for the first time a second generation detector in the design of FLIRs for the TRIGAT program, since then different types of IR equipment have been developed on the basis of this technology: (1) An infra-red seeker for the MICA missile. (2) Three types of IRST: VAMPIR MB for naval applications, SIRENE for the Army and OSF for the Rafale aircraft. (3) Three thermal imagers: Condor 1 for the mast mounted sight equipping the long range anti tank system, Tiger installed on the sight of the medium range antitank system, and Condor 2 for the pilot sight of the TRIGAT French-German helicopter. Infra-red detectors are MCT IR-CCD focal plane arrays developed by SOFRADIR with the objective of the best standardization possible in spite of different configurations and specifications for each program. In this paper, we intend to present the main features of this technology for these programs and the advantages obtained by comparison with the first generation in terms of performance. Industrialization of these products is starting now, and a specific effort has been made to standardize the components, especially the driving and read out electronics. A set of ASICs has been developed to make compact detection modules including a detector in his dewar, a cooling machine, and a proximity electronic.

  14. Exploring the relationship between object realism and object-based attention effects. (United States)

    Roque, Nelson; Boot, Walter R


    Visual attention prioritizes processing of locations in space, and evidence also suggests that the benefits of attention can be shaped by the presence of objects (object-based attention). However, the prevalence of object-based attention effects has been called into question recently by evidence from a large-sampled study employing classic attention paradigms (Pilz et al., 2012). We conducted two experiments to explore factors that might determine when and if object-based attention effects are observed, focusing on the degree to which the concreteness and realism of objects might contribute to these effects. We adapted the classic attention paradigm first reported by Egly, Driver, and Rafal (1994) by replacing abstract bar stimuli in some conditions with objects that were more concrete and familiar to participants: items of silverware. Furthermore, we varied the realism of these items of silverware, presenting either cartoon versions or photo-realistic versions. Contrary to predictions, increased realism did not increase the size of object-based effects. In fact, no clear object-based effects were observed in either experiment, consistent with previous failures to replicate these effects in similar paradigms. While object-based attention may exist, and may have important influences on how we parse the visual world, these and other findings suggest that the two-object paradigm typically relied upon to study object-based effects may not be the best paradigm to investigate these issues.

The objective of this study was to evaluate the toxicity of nanoparticles comprised of pristine graphene, reduced graphene oxide, graphene oxide, graphite, and ultradispersed detonation diamond in a U87 cell line. The scope of the work consisted of structural analysis of the nanoparticles using transmission electron microscopy, evaluation of cell morphology, and assessment of cell viability by Trypan blue assay and level of DNA fragmentation of U87 cells after 24 hours of incubation with 50 µg/mL carbon nanoparticles. DNA fragmentation was studied using single-cell gel electrophoresis. Incubation with nanoparticles containing the allotropes of carbon did not alter the morphology of the U87 cancer cells. However, incubation with pristine graphene and reduced graphene oxide led to a significant decrease in cell viability, whereas incubation with graphene oxide, graphite, and ultradispersed detonation diamond led to a smaller decrease in cell viability. The results of a comet assay demonstrated that pristine graphene, reduced graphene oxide, graphite, and ultradispersed detonation diamond caused DNA damage and were therefore genotoxic in U87 cells, whereas graphene oxide was not.Keywords: nanostructures, graphene, graphite, diamond, glioblastoma multiforme, geno toxicity

  18. Technology and function of grooved abraders in the early Neolithic of northwestern Europe

    Directory of Open Access Journals (Sweden)

    Caroline Hamon


    Full Text Available Found sporadically in late Palaeolithic and Mesolithic contexts, grooved abraders are among the most common tools found in Linear Pottery and Villeneuve-Saint-Germain settlements in north-western Europe (5,100-4,700 BCE. This paper presents an overview of the technical and functional characteristics of these tools in early Neolithic domestic contexts. Despite different blank morphologies and sizes, these tools tend to be relatively small in size and are generally not shaped. They are characterized by the use of a very specific raw material: low cohesive and generally ferruginous sandstones, chosen because their abrasiveness is enhanced through use. A classification of the different types of grooves is proposed, based on their shape, depth, section and localization. These characteristics are combined with use-wear analysis in order to propose a number of functional interpretations. Far from the widespread hypothesis that these tools functioned as shaft straighteners, we argue on the basis of the use-wear analysis and archaeological associations of items that these tools were primarily involved in the manufacture of bone and lithic tools, as well as of schist and limestone personal ornaments. They are evidence of the generalization and diversification of polishing and abrading techniques in the technical system of the first Neolithic populations. As such, they contribute to defining a whole new technical paradigm and are an essential element in any definition of the Neolithic.

    Regional surveys were carried out in different parts of North West Pakistan among domestic animals (N=57,921) including pets and livestock identifying cases of traumatic myiasis (n=1037). A total of four surveys focused general livestock population during Eid ul Adha (Eid surveys; incidence=1.21%) while another four surveys (Miscellaneous surveys; incidence=7.34%) targeted animal population brought to veterinary hospitals and dispensaries. Timeframe spanned four years from 2012 to 2015. Maggots were sampled and location of the wound was recorded for each host. Taxonomic identification used light and electron microscopic techniques. Our dataset shows three species as principle agents of myiasis (n=882) including Chrysomya bezziana Villeneuve (n=394), Wohlfahrtia magnifica (n=244) and Lucilia cuprina Wiedemann (n=244). Others (n=155) including Chrysomya megacephala (Fabricius), Chrysomya rufifacies (Macquart), Lucilia sericata (Meigen), Lucilia illustris (Meigen), Lucilia porphyrina (Walker), Hemipyrellia ligguriens (Wiedemann), Calliphora vicina (Robineau-Desvoidy), Sarcophaga crassipalpalis (Macquart) and Sarcophaga species were identified as species of minor importance. The obligatory screwworm species W. magnifica is a first report from Pakistan. The results based on this dataset are presented in a recent publication "Distribution Modeling of three screwworm species in the ecologically diverse landscape of North West Pakistan" (Zaidi et al., 2016) [1].

    Male genitalia of blow flies (Diptera: Calliphoridae) are distinctive in their morphological features and are often used for species identification. The aim of this work was to investigate the male genitalia of blow flies of medical and forensic importance from Thailand at the ultrastructural level, using scanning electron microscopy (SEM). Flies in two subfamilies were examined: Chrysomyinae [Chrysomya bezziana Villeneuve, Chrysomya chani Kurahashi, Chrysomya nigripes Aubertin, Chrysomya pinguis (Walker), Chrysomya rufifacies (Macquart), Chrysomya thanomthini Kurahashi & Tumrasvin, and Chrysomya villeneuvi Patton] and Luciliinae [Hemipyrellia ligurriens (Wiedemann), Hypopygiopsis infumata (Bigot), Hypopygiopsis tumrasvini Kurahashi, Lucilia cuprina (Wiedemann), Lucilia papuensis Macquart, Lucilia porphyrina (Walker), and Lucilia sinensis Aubertin]. Particular attention was paid to the main distinguishing features such as the shapes of the cercus and the surstylus, and the complex structure of the distiphallus. The differentiation of the male genitalia of these species at the SEM level is discussed and compared to the conditions in closely related species such as Chrysomya megacephala (Fabricius). A key for the identification of 14 blow fly species based on male genitalia is provided. Copyright © 2017 Elsevier B.V. All rights reserved.

In this tumor, the platelet-derived growth factor receptor, a tyrosine kinase receptor, is frequently hyperactivated. In the past, clinical case reports with imatinib, a tyrosine kinase inhibitor (TKI, have demonstrated tumoral stabilization. Here we describe the use of another TKI, masitinib, which specifically inhibits c-Kit, platelet-derived growth factor receptor, and Lyn, and is currently licensed for veterinary use in canine mast cell tumors. The therapeutic results were initially satisfactory, with regression of the tumor followed by tumoral recurrence which was stabilized and moderately reduced. Further studies are suggested, in order to evaluate the relevance of TKIs in the treatment and prevention of recurrences of feline injection site sarcoma. Tumoral stabilization by means of an inexpensive and reasonably well tolerated treatment would prove to be of true therapeutic relevance, in particular for inoperable feline injection site sarcomas. Another indication for such TKIs could be in preoperative treatment as a means of facilitating surgical excision by reduction of adhesions.Keywords: fibrosarcoma, imatinib, platelet-derived growth factor receptor, tyrosine kinase receptor

    This paper presents and discusses 30 cases of cadavers that had been transferred for forensic entomology investigations to the Department of Forensic Medicine, Faculty of Medicine, Chiang Mai University, northern Thailand, from 2000 to 2006. Variable death scenes were determined, including forested area and suburban and urban outdoor and indoor environments. The fly specimens found in the corpses obtained were the most commonly of the blow fly of family Calliphoridae, and consisted of Chrysomya megacephala (F.), Chrysomya rufifacies (Macquart) Chrysomya villeneuvi Patton, Chrysomya nigripes Aubertin, Chrysomya bezziana Villeneuve, Chrysomya chani Kurahashi, Lucilia cuprina (Wiedemann), Hemipyrellia ligurriens (Wiedemann), and two unknown species. Flies of the family Muscidae [Hydrotaea spinigera Stein, Synthesiomyia nudiseta (Wulp)], Piophilidae [Piophila casei (L.)], Phoridae [Megaselia scalaris (Loew)], Sarcophagidae [Parasarcophaga ruficornis (F.) and three unknown species], and Stratiomyiidae (Sargus sp.) were also collected from these human remains. Larvae and adults of the beetle, Dermestes maculatus DeGeer (Coleoptera: Dermestidae), were also found in some cases. Chrysomya megacephala and C. rufifacies were the most common species found in the ecologically varied death scene habitats associated with both urban and forested areas, while C. nigripes was commonly discovered in forested places. S. nudiseta was collected only from corpses found in an indoor death scene.

  5. L'ecole francaise et sa difficile insertion communautaire (United States)

    Forquin, Jean-Claude


    The author distinguishes between the different ways in which it is possible for the school to relate with the local community — by making school equipment generally available, by integrating the educational, social and cultural resources, by opening up education to real life, and by participation and control by parents and users. The difficulty for the French school system to penetrate and adapt itself to the communities in which it functions, is attributed to the tradition of administrative and bureaucratic centralisation manifested in the conception of teaching programmes and methods, as well as in the recruitment and management of personnel. Among recent educational innovations that could lead to a better association of the school with the community, one might mention first and foremost certain experiments concerned with the architectural and functional integration of educational, cultural and social facilities, conceived in a perspective of participation and `desegregation' of the community (e.g., in Yerres, Istres, and specially in Villeneuve, Grenoble). However, in the French context, such experiments are difficult to generalise from. It is equally difficult to effect any kind of control by parents over the functioning of educational institutions, or to open the curriculum to the realities of the local environment.

  6. Impact of screwworm eradication programmes using the sterile insect technique

    Vargas-Teran, M.; Hofmann, H.C.; Tweddle, N.E.


    The use of the sterile insect technique (SIT) in New World screwworm Cochliomyia hominivorax (Coquerel) eradication programmes has been successfully demonstrated. As a result of a 45-year area-wide campaign, suppression and eradication have been achieved in the USA, Mexico, Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama north of the Canal, some Caribbean Islands, and the outbreak in Libya, North Africa. The humans, livestock, and wildlife in these countries are now free of this dangerous pest. It has been estimated that the annual producer benefits are: USA - USD 796 million, Mexico - USD 292 million, and Central America - USD 77.9 million. In Libya, the estimated benefit/cost ratio was 5:1 in the infested zone, and 10:1 in the whole country. If the New World screwworm were eradicated in South America, it has been estimated that each year USD 3592 million could be saved. Small field trials have confirmed that the SIT would be effective for the area-wide control of the Old World screwworm Chrysomya bezziana (Villeneuve). (author)

  9. Distribution Modeling of three screwworm species in the ecologically diverse landscape of North West Pakistan. (United States)

    Zaidi, Farrah; Fatima, Syeda Hira; Khisroon, Muhammad; Gul, Ayesha


    North West Pakistan (NWP) is characterized by four eco-zones: Northern Montane Region, North Western Hills, Submontane Region and Indus Plains. Present study identified 1037 cases of traumatic myiasis in the region during 2012-2015. Screw worm larvae were classified as 12 species: Chrysomya bezziana (Villeneuve), Chryomya megacephala (Fabricius), Chrysomya rufifacies (Macquart), Lucilia cuprina (Wiedemann), Lucilia sericata (Meigen), Lucilia illustris (Meigen), Lucilia porphyrina (Walker), Hemipyrellia ligguriens (Wiedemann), Calliphora vicina (Robineau-Desvoidy), Wohlfahrtia magnifica (Schiner), Sarcophaga crassipalpalis (Macquart), Sarchophaga species. Among these C. bezziana, L. cuprina and W. magnifica with approximately 882 case reports were the principal agents of traumatic myiasis. The species W. magnifica is a first report from Pakistan. In order to investigate spatial distribution of these dominant species we used MaxEnt niche model. Our results revealed a well-established occurrence of C. bezziana and L. cuprina in the four eco-regions while W. magnifica is currently contained in the Submontane Region. Several hot spot areas of infestation were detected all characterized by high human population density showing synanthropic nature of these species. Wohlfahrtia magnifica was excluded from Northern Montane Region with severe winters and Southern Indus Plains with harsh summers revealing that invasive species are initially sensitive to extreme of temperatures. Presence of L. cuprina in the wet areas of North Humid Belt (Maximum annual precipitation: 1641mm) depicted a moisture preference of the species. In perspective of changing climate and future predictions of severe events such as droughts and flooding in NWP, W. magnifica can potentially alter the species composition. Considering these findings in an eco-geographically dynamic region of Pakistan we predict that two factors (1) Growing human population (2) Climatic conditions, equally contribute to range

  10. Review of forensically important entomological specimens in the period of 1972 - 2002. (United States)

    Forensic entomological specimens received by the Unit of Medical Entomology, IMR., from hospitals and the police in Malaysia in the last 3 decades (1972 - 2002) are reviewed. A total of 448 specimens were received. From these, 538 identifications were made with the following results: Eighteen species of cyclorrphaga flies were identified consisting of Chrysomya megacephala (Fabricius) 215 cases (47.99%), Ch. rufifacies (Masquart) 132 (29.46%), Ch. villeneuvi Patton 10 (2.23%), Ch. nigripes Aubertin 7 (1.56%), Ch. bezziana Villeneuve 4 (0.89%), Ch. pinguis (Walker) 1 (0.22%), Chrysomya sp. 47 (10.49%), Sarcophaga sp. 28 (6.25%), Lucilia sp. 21 (4.69%), Hermetia sp. 15 (3.35%), He. illucens (Linnaeus) 1 (0.22%), Hemipyrellia ligurriens (Wiedemann) 3 (0.67%), Hemipyrellia sp. 2 (0.45%), Ophyra spinigera 1 (0.22%), Ophyra sp. 6 (1.34%), Calliphora sp. 24 (5.36%), Synthesiomyia nudiseta (Wulp) 1 (0.22%) and Eristalis sp. 1 (0.22%). Other non - fly insect specimens are Pthirus pubis (Linnaeus) (Pubic louse) 2 (0.45%) and Coleoptera (Beetles) 1 (0.22%). Ch. megacephala and Ch. rufifacies were the commonest species found in cadavers from different ecological habitats. Sy. nudiseta is an uncommon species, thus far found only on cadavers from indoors. Sy. nudiseta is reported for the second time in Peninsular Malaysia. A total of 329 cases (73.44%) had a single fly infestation, 109 cases (24.33%) had double fly infestation and 10 cases (2.23%) had triple fly infestation. Five cases (1.12%) had eggs and 3 cases (0.67%) had larval stages that were not identifiable. No arthropods were retrieved from cadavers in 8 cases (1.79%). In conclusion, although large number of fly species were found on human cadavers, the predominant species are still those of Chrysomya.

The different techniques available for analyzing biometric and morphological items of the profile, eyes, ears, lips, and hard and soft palate are commented on and briefly compared with the respective bi-dimensional techniques. The available literature supports the use of three-dimensional ultrasound in difficult prenatal diagnostic conditions because of its diagnostic accuracy, enabling improved safety of perinatal care. Globally, a marked increase has been observed in the accuracy of three-dimensional ultrasound in comparison with the bi-dimensional approach. Because there is no consensus about the performance of the different three-dimensional techniques, future studies are needed in order to compare them and to find the best technique for analysis of each of the respective facial elements. Universal prenatal standards may integrate these potential new findings in the future. At this time, the existing guidelines for prenatal facial screening should not be changed.Keywords: prenatal three-dimensional ultrasound, prenatal screening, prenatal diagnosis, cleft lip and palate, fetal profile, retrognathism

  12. Insurance against an Old World screw-worm fly invasion of Australia

    International Nuclear Information System (INIS)

    Tweddle, Neil; Mahon, Rod J.


    Australia is fortunate that neither the New World screw-worm fly Cochliomyia hominivorax (Coquerel) (NWSWF) nor the Old World screw-worm fly, Chrysomya bezziana Villeneuve (OWSWF), have become established within our country, although much of the northern areas are environmentally suitable (Suthurst et al. 1989). The OWSWF is a substantial threat as it is prevalent in the neighbouring countries of Papua New Guinea and Indonesia. Perhaps more importantly, it is also present in many of our trading partners in Southeast Asia. The export of live cattle from northern Australian ports to Southeast Asian nations has become an important and rapidly expanding trade. The fly is also present near ports in the Middle East which receive considerable numbers of live sheep exported from various Australian ports. In both situations, there is the ever-present opportunity for the screw-worm fly (SWF) to return to Australia as larvae, pupae or adults on stock carrying vessels. While this means of transport probably represents the most likely route for the pest to gain access to Australia, accidental transport on aircraft and active myiases on humans or companion animals remain possibilities. The introduction of the NWSWF into Australia is considered unlikely, but not impossible. Indeed, in 1992, an Australian tourist returning from South America carried live NWSWF larvae into Australia in a neck wound. Fortunately, the diagnosis was made early and the wound was treated, preventing any larvae evacuating. This was in southern Australia in May, where climatic conditions are unlikely to favour survival at that time of the year, but it demonstrates the potential for inadvertent introduction. Models of the impact of the OWSWF indicate that the cost of an invasion would be high. It has been estimated by Anaman et al. (1993), that the annual cost in an average climate year to beef cattle, sheep and dairy producers of an endemic establishment would be A$281 million. These costs would be

  13. The Avignon Bridge: a 3d Reconstruction Project Integrating Archaeological, Historical and Gemorphological Issues (United States)

    Berthelot, M.; Nony, N.; Gugi, L.; Bishop, A.; De Luca, L.


    The history and identity of the Avignon's bridge is inseparable from that of the Rhône river. Therefore, in order to share the history and memory of the Rhône, it is essential to get to know this bridge and especially to identify and make visible the traces of its past, its construction, its interaction with the river dynamics, which greatly influenced his life. These are the objectives of the PAVAGE project that focuses on digitally surveying, modelling and re-visiting a heritage site of primary importance with the aim of virtually restoring the link between the two sides which, after the disappearance of the Roman bridge of Arles, constituted for a long time the only connection between Lyon or Vienna and the sea. Therefore, this project has an important geo-historical dimension for which geo-morphological and paleoenvironmental studies were implemented in connection with the latest digital simulation methods exploiting geographic information systems. By integrating knowledge and reflections of archaeologists, historians, geomorphologists, environmentalists, architects, engineers and computer scientists, the result of this project (which involved 5 laboratories during 4 years) is a 3D digital model covering an extension of 50 km2 achieved by integrating satellite imagery, UAV-based acquisitions, terrestrial laser scanning and photogrammetry, etc. Beyond the actions of scientific valorisation concerning the historical and geomorphological dimensions of the project, the results of this work of this interdisciplinary investigation and interpretation of this site are today integrated within a location-based augmented reality application allowing tourists to exploring the virtual reconstruction of the bridge and its environment through tablets inside the portion of territory covered by this project (between Avignon and Villeneuve-lez-Avignon). This paper presents the main aspects of the 3D virtual reconstruction approach.

Des mesures du meme ordre ont ete effectues par une autre methode dans l'helium ensemence au cesium contenu dans une enceinte isotherme portee a 1900 deg. K. La aussi les valeurs d'equilibres concordent tres correctement mais l'ionisation hors d'equilibre parait etre inferieure aux valeurs previsibles. On a examine dans une etude theorique l'effet du chauffage electronique a l'interieur du convertisseur dans le cas de l'argon et du potassium. Cette etude met en evidence l'importance d'un fractionnement fin des electrodes le long du canal. Elle montre par ailleurs que le chauffage electronique dans l'argon potassium peut etre provoque par des champs magnetiques de 1 a 2 Ts. Il est prevu l'installation d'un vaste banc experimental qui fonctionnera sur un principe analogue aux souffleries a rafales. Le generateur de gaz delivrera des rafales d'helium ensemence au cesium porte a une temperature de 2100 deg. K.

    Volcanic emissions can have a significant effect on the environment, and may impact climate through the injection of gases and aerosols in the upper troposphere where they have a long residence time and an impact on clouds formation [Makkonen et al., 2012]. The Piton de La Fournaise volcano on La Réunion Island erupted four times in 2015 [Peltier et al., 2016] and volcanic particles were ejected in the atmosphere both as primary particles rapidly deposited due to their large size and secondary particles mainly derived from oxidation of sulphur dioxide. In this study, we focus on this secondary process of forming new aerosol particles (NPF). Sulphuric acid (H2SO4), resulting from SO2 oxidation in the presence of light, is known to be the major precursor to nucleation events [kulmala et al., 2004 and Kerminen et al., 2010]. During the April 2007 eruption of Piton de la Fournaise, Tulet and Villeneuve [2010] estimated by OMI and CALIOP space sensors analysis a total SO2 release of 230 kt, among of which 60 kt that have been transformed into H2SO4 supposing NPF processes. However, the nucleation phenomenon has rarely been directly observed in volcanic environments [Kulmala et al., 2004] except for Mauna Loa volcano on Hawaii [Weber et al., 1995] and for Eyjafjallajokull plume caught at the Puy de Dôme station [Boulon et al., 2011]. Within the STRAP project (Synergie Trans-disciplinaire pour Répondre aux Aléas de Panache Volcanique), a multidisciplinary tracking of a volcanic gas and aerosol plume that has been conducted by Tulet et al. [2016] through a strong collaboration between volcanologists and meteorologists. Part of the measurements were performed at Maïdo observatory (21.1° S 55.4° E) which is located at 40 km from the volcano but which has been reached several times by the volcanic plume, each time accompanied by a NPF event. A statistical analysis of the influence of the plume presence on the NPF frequency, intensity and new particles growth rates is

  18. A Real Options Approach to Nuclear Waste Disposal in Sweden

    International Nuclear Information System (INIS)

    Soederkvist, Jonas; Joensson, Kristian


    This report is concerned with an investigation of how the real options approach can be useful for managerial decisions regarding the phase-out of nuclear power generation in Sweden. The problem of interest is the optimal time-schedule for phase-out activities, where the optimal time-schedule is defined in purely economical terms. The approach taken is actual construction and application of three real options models, which capture different aspects of managerial decisions. The first model concerns when investments in deep disposal facilities should optimally be made. Although the model is a rough simplification of reality, the result is clear. It is economically advantageous to postpone deep disposal forever. The second model focuses on how the uncertainty of future costs relates to managerial investment decisions. Construction of this model required some creativity, as the nuclear phase-out turns out to be quite a special project. The result from the second model is that there can be a value associated with deferral of investments due to the uncertainty of future costs, but the result is less clear-cut compared to the first model. In the third model, we extend an approach suggested by Louberge, Villeneuve and Chesney. The risk of a nuclear accident is introduced through this model and we develop its application to investigate the Swedish phase-out in particular, which implies that waste continuously disposed. In the third model, focus is shifted from investment timing to implementation timing. The results from the third model are merely qualitative, as it is considered beyond the scope of this work to quantitatively determine all relevant inputs. It is concluded that the phase-out of nuclear power generation in Sweden is not just another area of application for standard real options techniques. A main reason is that although there are a lot of uncertain issues regarding the phase-out, those uncertainties do not leave a lot of room for managerial flexibility if

  19. Spatial and Temporal Variations in Diatoms from la Chaine des Lacs Urban Watershed, Nord-Pas France, in Relation to Water Quality (United States)

    Noble, P. J.; Van de Vijver, B.; Verleyen, E.; Prygiel, J.; Ivanovsky, A.; Lesven, L.; Billon, G.


    Diatom analysis was conducted on lake sediments in la Chaîne des Lacs (CDL), a shallow eutrophic urban park and storm control system in Villeneuve d'Ascq, France, to address both the present day water quality, and the evolution of this urban system over its 40 year history. The main lake, Lac du Héron (LDH), received recent attention because of water quality problems, including eutrophication, harmful algal blooms, and invasion by the macrophyte Elodea in 2012. A total of 17 sites were collected in CDL, 11 of which were in LDH, to document spatial variability, and a 26cm long core addresses historical changes. The bulk of the diatom assemblage in LDH can be classified as both eutrophic and moderately metal tolerant, using modern national diatom indices developed and used by the French regional water agencies. Surface sediment samples within LDH show large spatial variations in %Cocconeis placentula whose habitat is epiphytic growth on Elodea. Other variation is reflected in the phytoplankton composition both spatially, and interannually. Aulacoseira muzzanensis and Cyclostephanos dubius showed greater abundance in the open water habitats in LDH, whereas sites in CDL outside of LDH had greater Cyclotella meneghiniana. Temporally, Stephanodicsus (largely S. hantzschii), the dominant diatom in early spring, were present in greater abundances in the 2016 surface sediment samples than in any of the 2015 samples. One possible explanation is that the 2016 samples, taken March 30th, preferentially preserved the early spring Stephanodiscus bloom, in contrast to the 2015 samples, which were taken in January. The sediment core provides an historical record, where the uppermost 4cm plot with the bulk of the LDH surface samples and contain abundant Cocconeis, 4 -14cm is phytoplankton-rich, largely Cyclostephanos dubius and Aulacoseira muzzanensis, and represents a less weed-choked environment prior to the 2012 Elodea invasion. The base of the core is dominated by Amphora and

    The Heron lake is a storm-water pond of 30 hectare constructed in the 70's to avoid the flooding in the city of Villeneuve d'Ascq (Lille urban area in Northern France). This facility could also receive some untreated urban wastewaters during high rainfall events. The water level is regulated by automatic pumps, which periodically discharge the overflow into a natural watercourse, the Marque River. Located in an urban area, the lake is qualified as eutrophic because of the high nutrients concentration, which stimulates the presence of cyanobacteria. Recently, the invasive macrophyte Elodea nuttallii colonized the lake. This proliferation causes ecological troubles like anoxic events or even obstruction of the pumps, thereby increasing the risk of flooding. Two types of monitoring (low and high frequencies) were implemented to assess the functioning of this lake and to estimate its impact to the river. The low frequency monitoring consisted on punctual screenings on the dissolved phase and monthly grab samplings from February 2014 to February 2015. Physicochemical parameters (oxygen, temperature, conductivity, pH, solid particulate matter, dissolved organic carbon) and nutrients (NO3-, NH4+ and PO43-) were recorded. Additionally, a high frequency monitoring was undertaken (with measurements every 10 minutes) was performed by using a buoy equipped with different sensors for measuring oxygen, turbidity, temperature, conductivity, pH and phytoplankton pigments. Furthermore, both the discharge lake flow and the pluviometry were recorded at the scale of the day. Although all the data are not yet fully interpreted, several key points have already been evidenced: (i) at the entrance of the lake, the water is enriched in urban sewage; (ii) some significant differences of oxygenation exist between the entrance and the rest of the lake due to both waste waters inputs in the entrance channel and atmosphere-water interactions; (iii) eutrophication occurs at the beginning of the

    An health impact assessment of air pollution based on the I.n.V.S. guidelines has been conducted in Avignon according to the Regional Plan for the quality of air in the region of Provence Alpes Cote d'Azur. Short term impact of atmospheric pollution has been estimated in term of mortality (total, cardiovascular and respiratory mortality) and hospital admissions (for respiratory, cardiovascular and cardiac reasons) attributable to air pollution. Long-term impact was also assessed by the number of deaths due to atmospheric pollution. The study has been carried out in seven cities homogeneously exposed belonging to Vaucluse (Avignon, Le Pontet, Morieres les Avignon, Sorgues and Vedene) and two cities of the Gard department (les Angles and Villeneuve les Avignon) representing a study population of 153,624 inhabitants. Two period of study have been defined: period 1999-2000 for short and long term evaluations on the mortality and the year 2001 for the morbidity analysis. This study rests on methodological principles of E.I.S. (evaluation of sanitary impact) of urban air pollution whom methodology is in four steps: identification of dangers, exposure estimation, choice of exposure-risk relationship and risk characterisation. The pollutions indicators are built from four pollutants nitrogen dioxide, ozone, sulfur dioxide and PM{sub 10}. The exposure-risk relationships used come from epidemiological studies realised in general population, by preferring the multi centers studies and European ones. The number of deaths by year due to air pollution is 23, whom 10 by cardiovascular diseases, 2 by respiratory diseases. The most efficient scenario are these ones corresponding to air pollution decreases of 25% in the considered pollutant. About the long term sanitary benefits, the different scenario show that the European norm forecasted for 2005 is respected. The respect of the European norm expected for 2010 should allow to avoid 10 deaths on the totality of registered

  4. Enabling technologies to improve area-wide integrated pest management programmes for the control of screwworms. (United States)

    Robinson, A S; Vreysen, M J B; Hendrichs, J; Feldmann, U


    The economic devastation caused in the past by the New World screwworm fly Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) to the livestock industry in the U.S.A., Mexico and the rest of Central America was staggering. The eradication of this major livestock pest from North and Central America using the sterile insect technique (SIT) as part of an area-wide integrated pest management (AW-IPM) programme was a phenomenal technical and managerial accomplishment with enormous economic implications. The area is maintained screwworm-free by the weekly release of 40 million sterile flies in the Darien Gap in Panama, which prevents migration from screwworm-infested areas in Columbia. However, the species is still a major pest in many areas of the Caribbean and South America and there is considerable interest in extending the eradication programme to these countries. Understanding New World screwworm fly populations in the Caribbean and South America, which represent a continuous threat to the screwworm-free areas of Central America and the U.S.A., is a prerequisite to any future eradication campaigns. The Old World screwworm fly Chrysomya bezziana Villeneuve (Diptera: Calliphoridae) has a very wide distribution ranging from Southern Africa to Papua New Guinea and, although its economic importance is assumed to be less than that of its New World counterpart, it is a serious pest in extensive livestock production and a constant threat to pest-free areas such as Australia. In the 1980s repeated introductions and an expansion of Old World screwworm populations were reported in the Middle East; in the 1990s it invaded Iraq and since late 2007 it has been reported in Yemen, where a severe outbreak of myiasis occurred in 2008. Small-scale field trials have shown the potential of integrating the SIT in the control of this pest and various international organizations are considering using the release of sterile insects as part of an AW-IPM approach on a much wider scale

  5. Reciprocity and gyrotropism in magnetic resonance transduction

    International Nuclear Information System (INIS)

    Tropp, James


    We give formulas for transduction in magnetic resonance - i.e., the appearance of an emf due to Larmor precession of spins - based upon the modified Lorentz reciprocity principle for gyrotropic (also called 'nonreciprocal') media, i.e., in which a susceptibility tensor is carried to its transpose by reversal of an external static field [cf., R. F. Harrington and A. T. Villeneuve IRE Trans. Microwave Theory and Technique MTT6, 308 (1958)]. Prior applications of reciprocity to magnetic resonance, despite much success, have ignored the gyrotropism which necessarily arises due to nuclear and/or unpaired electronic spins. For detection with linearly polarized fields, oscillating at the Larmor frequency, the emf is written in terms of a volume integral containing a product of two factors which we define as the antenna patterns, i.e. (H 1x ±iH 1y ), where, e.g., for a single transceive antenna, the H's are just the spatially dependent oscillatory magnetic field strengths, per the application of some reference current at the antenna terminals, with the negative sign obtaining for transmission, and the positive for reception. Similar expressions hold for separate transmit and receive antennas; expressions are also given for circular polarization of the fields. We then exhibit a receive-only array antenna of two elements for magnetic resonance imaging of protons, which, due an intensity artifact arising from stray reactive coupling of the elements, produces, despite its own bilateral symmetry, asymmetric proton NMR images of a symmetric cylindrical phantom containing aqueous saline solution [J. Tropp and T. Schirmer, J. Magn. Reson. 151, 146 (2001)]. Modification of this two-port antenna, to function in transmit-receive mode, allows us to demonstrate highly nonreciprocal behavior: that is, to record images (of cylindrical test phantoms containing aqueous saline solution) whose appearance dramatically changes, when the roles of transmission and reception are swapped between

If the pain is not well managed, negative outcomes may ensue. To our knowledge, there is no measure in English that assesses patient’s satisfaction with postoperative pain management following idiopathic scoliosis surgery. The aim of the present study was to assess the psychometric properties of the satisfaction subscale of the English version of the Satisfaction of Adolescents with Postoperative pain management – idiopathic Scoliosis (SAP-S scale.Methods: Eighty-two participants aged 10–18 years, who had undergone spinal fusion surgery, fully completed the SAP-S scale at 10–14 days postdischarge. Construct validity was assessed through a principal component analysis using varimax rotation.Results: Principal component analysis indicated a three-factor structure of the 13-item satisfaction subscale of the SAP-S scale. Factors referred to satisfaction regarding current

    monitored systematically from August 2008 to August 2009. Methods: Water samples (0.5 L) were collected in borosilicate bottles with Teflon caps, pre-filtered with glass wool (Roth, Germany) and glass fibre filter (Millipore, USA), solid-phase extracted (Phenomenex, C18-E) and quantified using GC-MS (Agilent 6890). For quality assurance samples and blanks were spiked with a surrogate standard (d-HCH). The recovery of the surrogate standard was used to monitor for matrix effects and sample processing errors. Surrogate recovery was evaluated by a recovery standard (Fluoren-d10) spiked to the sample after the extraction. Results: A total of 434 samples (253 samples in Ba Lang, 119 samples in An Long and 62 drinking water samples) were collected from August 2008 to August 2009. In An Long 13 of the 15 target compounds were detected in water samples. Average residue concentrations ranged from 0.01 to 3.96 ?g/l. The fungicide isoprothiolane and the insecticide buprofezin occurred with the highest concentrations (up to 20.77 and 16.53 ?g/l, respectively). In Ba Lang, 12 of the 15 monitored pesticides were detected with an average concentration from 0.01 to 0.30 ?g/l. The fungicide isoprothiolane was detected with highest (up to 12.86 ?g/l). In 70% of all samples more than four different pesticides were detected. Their effect may add up and pose risk to humans and aquatic organisms. In rural areas surface water is frequently used as drinking water source. First results from a sampling program of drinking water indicate that locally used water treatment methods (precipitation with aluminium sulfate followed by boiling) were not appropriate to reduce the pesticide exposure of the consumer. Through evaporation, boiling of drinking water even increased the concentrations of some non-volatile pesticides. References Carvalho, F. P., Villeneuve, J.P., Cattini, C., Tolosa, I., Thuan, D.
