  1. Saussure chiama, pascoli risponde. Nuove prospettive sulla ricerca anagrammatica

    Directory of Open Access Journals (Sweden)

    Giovanni Palmieri

    2016-07-01

    Full Text Available Dopo un’ampia e aggiornata ricostruzione storico-filologica della corrispondenza tra Saussure e Pascoli, l’articolo suggerisce nuove prospettive sulla ricerca ana-grammatica negando che esista uno iato insanabile tra il Saussure degli anagrammi e quello del Cours. Per dimostrare ciò, l’autore si avvale anche degli scritti saussuriani ritrovati nel 1996. In particolare, Saussure avrebbe ‘scoperto’ il significante (elemento linguistico individuato in contrapposizione alla figure vocale e le serie paradigmatiche proprio a partire dalla sua ricerca sulle associazioni foniche presenti nelle strutture anagrammatiche del linguaggio (poetico. Inoltre, a partire da una riflessione sul principio di similarità fonica, il confronto tra le due ricerche saussuriane consente di limitare il preteso dogma dell’arbitrarietà del segno. Ciò in perfetto accordo con Jakobson. Sviluppando poi un’intuizione di Meillet, viene analizzato il rapporto che esiste tra anagrammi e musica (dodecafonica, nel caso in questione. Chiude l’articolo una lettera immaginaria, ma non troppo, con la quale Pascoli avrebbe potuto rispondere a Saussure sulla questione degli anagrammi presenti nel testo poetico.

  2. Orientalismi: nuove prospettive interpretative

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available This paper is aimed at reconsidering the concept of Orientalism in a new and multiple perspective, and at proposing a different interpretation of the relationship between culture and power, starting from Edward Said’s theoretical frame of reference. If Said’s representational model is repositioned out of structuralist and foucaultian frameworks and separated from the gramscian idea of hegemony-subordination, indeed, it may be possible to re-discuss the traditional profile identifying the Other in the European cultures. My basic assumption here is that Orientalism should not be understood as a consensus mechanism, which is able to produce diversified images of the Orient and the Oriental on demand. Although, of course, in most cases Orientalism is connected to the issue of power, its meanings could also be explained —as it will be soon shown— otherwise. Let’s take The Invisible Cities by Italo Calvino as an example. Here the narratives are not just multiple repetitions of Venice —in Said’s case, the same would hold for Europeanism—, but they could be strategically re-appropriated by those “others” and “alterities” whose bodies and identities are imposed by the Eurocentric discourse. In this sense, a double link may be identified with queer theories and postcolonial studies, and the notion of subordination will be rethought. Finally, from the above mentioned borders, a new idea of image emerges, which appears as linear, uniform and flattened only to the European gaze, whereas in actual fact it is made of imaginaries and forms of knowledge, which combine representation with the conceptualization of power relationships.

  3. Nuove prospettive per la storia d'impresa

    Full Text Available La historia de la empresa es una disciplina abierta que puede incluir, además de las cuestiones relacionadas con la evolución de la economía, las empresas, el mercado y el mundo empresarial, otros ámbitos institucionales, culturales y sociales relacionados con los acontecimientos contemporáneos como resultado de un largo proceso de industrialización. La primera revolución industrial se inició a finales del siglo XVIII, seguida por una profunda transformación industrial que tuvo lugar en la segunda mitad del siglo XIX, la industrialización masiva del siglo XX y el nuevo escenario post-fordista del siglo XXI son los hitos históricos de un fenómeno que ha acompañado las diferentes etapas de desarrollo y la economía mundial durante el período que se caracterizó por la supremacía de la producción capitalista. En resumen, la historia de la empresa es un elemento esencial, en términos de calidad, para la comprensión de la estructura económica de un país desde una perspectiva dinámica y un punto de vista comparativo. No es sorprendente que, a comienzos del siglo XX la historia de la empresa saltó de los Estados Unidos en relación con el modelo del "big business", como un análisis y un profundo examen de la actividad, incluso de un aspecto crítico, se dirigió a algunos tipos de desarrollo y estrategias de la empresa. Como está escrito por Alfred D. Chandler: «La historia de la empresa apareció por primera vez como distinguible sub-campo de la historia económica a finales de los 1920 y en los 1930. Su predecesor, la historia económica, se convirtió en una disciplina identificable sólo unos años antes». La primera Cátedra de Historia de la Empresa se activó en 1927 en la Harvard Business School, y fue cubierta hasta mediados del siglo pasado por Norman SB Gras, que se ha decidido dividir la historia de la empresa en seis periodos diferentes: “Pre-business capitalism”, “Petty capitalism”, “Mercantile capitalism”, “Industrial capitalism”, “Financial capitalism”, “National capitalism”. Después de la Segunda Guerra Mundial, Joseph Schumpeter y Arthur H. Cole han fundado el Center for Research in Entrepreneurial History, donde especialistas como Alfred D. Chandler, Thomas Cochran y Landes David fueron capacitados. Ellos estuvieron involucrados en el análisis de la iniciativa empresarial, la relación entre empresas y la sociedad, el papel de la innovación, la relación entre estrategia y estructura, y la capacitación para las organizaciones. Por lo tanto, la experiencia de Estados Unidos sirvió como marcador de pauta en muchos otros Países, donde la historia de la empresa había conocido una amplia difusión de la segunda mitad del siglo pasado. La posibilidad de utilizar archivos corporativos de una manera sistemática ha comenzado a entrar en vigor en Alemania desde 1907, cuando el Archivo de Renania-Westphalisch se estableció. Esto se ha convertido en un punto de referencia para la apertura de instituciones similares en muchos Países. En términos generales, las fuentes para la historia de la empresa se pueden dividir en cuatro tipos diferentes: los generados por la propia empresa -clasificada en primaria y secundaria-, las originadas fuera de la empresa -por ejemplo, las instituciones públicas, sindicatos y asociaciones- y las fuentes orales. La metodología tradicional de investigación en Historia de la Empresa se centra en el uso de las fuentes principales, representadas, sobre todo, de los archivos de empresas. El advenimiento de la "sociedad de la información", no sólo se centra en el cambio de paradigmas tradicionales económico, sino también un profundo replanteamiento de la producción científica, y la distribución del conocimiento. La introducción y el uso de fuentes electrónicas no es un mero efecto de sustitución de antiguos instrumentos, sino una ayuda extraordinaria para seguir avanzando en una disciplina como la historia de la empresa.

  7. Nuove prospettive di ricerca: il 'dentro' e il 'fuori' delle narrazioni

    Directory of Open Access Journals (Sweden)

    Maria Ermelinda De Carlo

    2006-09-01

    Full Text Available Tra le righe di uno scritto, attraverso le rappresentazioni e le interpretazioni, è possibile ritrovare schegge di un originale smarrito, ma non si può ricostruire oggettivamente e interamente la vita veramente vissuta. La scelta sintagmatica e paradigmatica, consapevole e/o inconsapevole, nasce infatti da un’impalcatura, da schemi mentali con cui l’uomo convive da sempre. Una storia e una frase dicono molto di più di quel che dicono. La densità di significazione e tutti i mondi che ci sono dietro ad alcuni sostantivi, verbi, avverbi, aggettivi restano il più delle volte un segreto. Il punto di vista narrativo si pone, dunque, come potenziale chiave euristica ed ermeneutica in grado di esplorare e recuperare patrimoni di esperienze di vita dei soggetti. La scrittura consente al soggetto di raccontarsi e di raccontare un io nascosto e rappresenta un tentativo di strapparsi quella ‘maschera di ferro’ che nasconde le emozioni, di andare ‘oltre la soglia’, di dare sfogo ad un’identità più o meno autentica, di comprendere orientamenti e percorsi di senso. Essa è l’esito di chi narra che, uscito dalla polarità dello schema lineare della vita, affianca se stesso in modo tale da avere uno sguardo sul sistema di insieme di cui è parte.

  8. Uva da tavola ipocalorica, possibilità di coltivazione e nuove prospettive di mercato

    Full Text Available According to the CODEX STAN 255 (2007, table grapes can be harvested when the refractometric index reaches at least 16° Brix. Grapes with a lower refractometric index are accepted provided the sugar/acid ratio (Total Soluble Solids/Tritatable Acidity – TSS/TA is at least equal to 20:1 if the Brix level is comprised between 12.5° and 14° Brix, 18:1 if the Brix level is comprised between 14° and 16° Brix. Some table grapes grown in Mediterranean climate can accumulate TSS higher than 16° Brix, with low levels of acidity, thus leading to a TSS/AT ratio even greater than 30: 1. Grapes that accumulate TSS less than 12.5° Brix and low TA levels, hardly reach the recommended ratio TSS/TA of 20:1, rather stopping at lower values. Based on these considerations in 2012 an experimental trial of four years started on a total of 103 table grape cvs. Phenological phases in relation to the acidic and sugar content were measured in order to assess the TSS/TA ratio and build regression lines with TSS. Almost all cvs. showed a significant linear regression, with R2 values higher than 0.80 and a standard error between 00.18 and 1.74. TSS values of 103 cvs. at TSS/TA ratio of 20:1, predicted by means of linear regression equations, , were subjected to cluster analysis based on Euclidean Distance. We identified nine clusters, of which the first two with the predicted TSS between 10.04° and 11.77° Brix (7 cvs. and 12.08° and 12.62° Brix (7 cvs., respectively. Some of the cvs. showing TSS values below 12.5° Brix at the TSS/TA of 20: 1, were subjected to a test panel of 24 tasters, who were asked to indicate the acceptability of these grapes on hedonic scale of 9 points. Preliminary results showed that for some table grapes with TSS below 12.5° Brix, a SST/AT ratio lower than the recommended 20:1 can be proposed, while preserving an acceptability by the consumer. These results suggest a more modern perspective on grapes nutritional intake, which takes into account the real needs of Western countries where diabetes, hyperglycemia, obesity and cardiovascular diseases are the main dismetabolisms arising from a diet too rich in calories. These grapes thus represent a new frontier and an opportunity for producers of table grapes, who want to enterprise a market share on “grape diet”, and represent a genetic basis for breeding aimed at obtaining new hypocaloric grape cultivars.

  9. Un’altra storia: Nuove prospettive sul cantiere della cupola di Santa Maria del Fiore

    2015-09-01

    Full Text Available ‘Un’altra storia’ (Another History is a first attempt to test the potential of detailed administrative documentation to deepen and, where necessary, modify our understanding of the creative process around the great worksite of Florence Cathedral. It treats two case studies chosen to exemplify possible strategies of navigation in the vast documentary corpus now accessible online in the website, The Years of the Cupola. The first study centers upon the person of Jacopo di Sandro, a hitherto scarcely known master stonecutter employed in the Opera di Santa Maria del Fiore workforce during the entire documented period. He distinguished himself from the very beginning for exceptional flexibility of services rendered, from day labor to a series of special assignments, including the supervision of separate worksites and of the forests in Casentino; Jacopo also emerges as an occasional entrepreneur whose independent contracts coexisted with his status as daily wage earner. At the end of the period he entered the ranks of salaried executive personnel as the administrator of the Brunelleschian fortress of Vico Pisano, demonstrating a notable fluidity amongst labor typologies which are often treated as non-communicating vessels. The second query is dedicated to the documentation on the stone components commissioned for the ‘serraglio’, or closing ring, at the top of the dome, believed to function as stabilizer of the whole self-supporting structure up to the base of the lantern. A census of the sources reveals the number, dimensions, price and delivery dates of the various orders of sandstone blocks, typically supplied in multiples of eight, the number of segments of the octagonal structure. The results are presented as an invitation to look below the surface of the masonry and consider the rationale for so much strength and weight when analyzing the dynamics of this area.

    In the framework of the high temperature superconducting materials, YBa{sub 2}Cu{sub 3}O{sub 7} (YBCO) shows very interesting intrinsic superconducting transport properties at temperature higher than the liquid nitrogen temperature. These properties are very important in large scale applications: transport of energy, magnets, transformers, etc. Unfortunately the potential of this material cannot be achieved today, since it is very difficult to manufacture YBCO based tapes or cables. In the last years several groups have tried to overcome the problems with new fabrication techniques. In the present report the state of the art and the prospective in the field of YBCO film fabrication on metallic substrates are presented.

    Full Text Available In contrasto con quella che era stata la tradizione dell’empirismo classico di matrice hobbesiana e lockiana da un lato, e la tradizione razionalista a erente al nucleo loso co cartesiano, Merleau-Ponty elabora una “terza via” che si propone di riportare la conoscenza nell’ambito dello stretto rapporto tra il corpo e i fenomeni che esso esperisce in quanto corpo vivente e non mero oggetto tra gli oggetti. Il mio corpo non è, come credeva convintamente Cartesio, mera res extensa, separata dalla mia più pura e vera essenza di res cogitans; anzi è proprio col mio essere corpo vivente che conosco pienamente il mondo. Noi non costruiamo il mondo naturale, ma lo viviamo. È in esso che avviene l’incontro con l’Altro, l’incontro di prospettive che ci mette alla prova nell’agire morale; è in questo incontro che nasce il senso che esso assume per noi. È in questo rapporto d’intersoggettività che si genera il nodo di signi cati che costituisce il mondo culturale e più ancora quello morale. In questo contesto l’ottica del corpo vissuto costituisce un presupposto radicale che modi ca n dal principio il rapporto tra soggetto e mondo, tra soggetto singolo e altri individui.

    Full Text Available Surrogare lo spostamento fisico attraverso il flusso telematico, spostare i bit e non gli atomi, può oggi essere ritenuta una forma di “mobilità sostenibile” che non produce effetti impattivi sul sistema fisico urbano. La cybermobility è quindi considerabile come una forma di softmobility che può consentire di spostarsi virtualmente per raggiungere un’attività urbana e per fruire di uno specifico servizio (effettuare operazioni bancarie via rete, ottenere un certificato on-line, acquistare beni via Internet, etc.. Tuttavia, analizzando i numerosi contributi presenti nella letteratura internazionale sull’argomento, si comprende come lo spostamento, per effetto delle nuove tecnologie info-telematiche tenda a modificarsi, ma non a dissolversi. L’articolo propone un ribaltamento dei termini della riflessione che riguarda il potere sostitutivo dei flussi fisici di mobilità da parte delle (NTI. In particolare si considera la possibilità che le funzioni urbane possano subire un processo di “virtualizzazione” per effetto delle NTI. Tale processo, opportunamente indirizzato, potrebbe forse consentire il raggiungimento di una “soglia” al di sopra della quale si verifica l’effettiva virtualizzazione dello spostamento.

    This paper focuses on state-of-the-art materials recovery techniques employed in the solidification/stabilization of industrial wastes. Particular consideration is given to the Italian situation. After a review, with reference to waste/matrix compatibility inherent problems, of the presently employed main encapsulation techniques (with matrices based on cement, lime, clay, thermoplastic materials, organic polymers, macroencapsulating compounds), attention is addressed to solidification systems which allow a recovery of the waste material as low-technology by-products. Regarding the most important industrial waste streams: thermoplastic refuse, incinerator ashes, chemical sludges, the paper reviews efforts devoted not only to their chemical fixation in order to fulfill the current land disposal requirements, but mainly to their employment for production of manufactured articles.

    Full Text Available ItSotto la spinta dei cambiamenti socio-economici e di significativi progressi tecnici, la gestione dei giardini storici e degli spazi verdi in genere, sta vivendo un periodo di forte cambiamento ed evoluzione. Nel tentativo di razionalizzare l’uso delle risorse naturali e umane, nascono nuovi servizi che fanno intravedere la necessità di creare specifiche figure professionali, in grado di colmare in tempi rapidi il divario tra le potenzialità applicative offerte dalle nuove tecnologie e le diverse realtà operative, ancora legate all’uso di pratiche e metodologie tradizionali. Anche nel settore dei giardini e dei parchi storici è giunto il momento di approfondire i temi relativi alla loro conservazione e valorizzazione, che oggi sono strettamente legati a una concreta sostenibilità economica e ambientale delle pratiche di gestione e di promozione. Queste considerazioni sono state alla base di una serie di iniziative e di progetti promossi a livello nazionale ed europeo, che, grazie all’integrazione di strumenti ICT, SMART-Sensors e IA, in alcuni casi si sono concretizzati nella realizzazione di metodologie e soluzioni di grande interesse operativo.Le procedure e i criteri presentati in questo articolo sono il risultato dell’attività di ricerca e trasferimento tecnologico condotta dal CNR-IBIMET di Firenze negli ultimi dieci anni. Già nella sua versione prototipale, il sistema proposto mostra tutte le sue potenzialità di monitoraggio e supporto alle attività gestionali e manutentive degli spazi verdi, aprendo la strada a una progressiva automazione e virtualizzazione delle procedure (creazione di scenari, elementi essenziali per la successiva valorizzazione e promozione del bene a livello sociale e culturale.In particolare, oltre allo schema logico del sistema, si discutono alcune tra le funzioni di monitoraggio di maggiore interesse (disponibilità idrica, stato fitosanitario e fenologia, evidenziando quali siano i vantaggi

In particolare nuovi spunti vengono offerti dal ritrovamento di un documento autografo di Plombeolo de’ Plombeoli, autore della nota di possesso a c. 196v, e dalla scoperta della firma erasa di Jacopo Plombeoli, finora mai notata, all’interno del manoscritto. Grazie allo studio delle miniature e al confronto di queste con altri apparati decorativi si offre una nuova ipotesi circa il luogo di produzione del manufatto, che andrebbe collocato in area crociata e più precisamente ad Antiochia.In this contribute new hypotheses about the origins and ancient history of the Ambrosian Roman de Troie manuscript (Milan, Biblioteca Ambrosiana, D 55 sup. are presented. These were formulated after a very careful analysis of the codex itself and studying several archival evidences. In particular, new insights are offered by the discovery of an autograph document by Plombeolo de Plombeoli, author of the note of ownership a. c. 196, and by the presence of Jacopo Plombeoli scraped off signature inside the document, never noticed before. The accurate study of the miniatures and their comparison with other decorations of the same time and context arise a new hypothesis about the codex place of production. According to it, the origins of the manuscript should be located in the crusader area and more precisely in Antioch.

    Full Text Available The negotiable time certificate of deposit (CD has played an important role in the competitive struggle of commercial banks in the US since 1961, enabling them to tap sources of funds they had neglected since the banking reforms of the 1930s. The aggressive employment of the CD has already brought about various changes in banking practices, and may lead to further modifications in the functions performed by commercial banks and in the banking structure. The present article is devoted to the CD phenomenon as it affects the role of commercial banks as financial intermediaries and the structure of the banking industry. The effects of interest rate regulation on the development of the CD as a potential source of funds is also considered. The author concludes that the emergence of the CD, while overcoming some of the barriers to effective competition in the financial markets, has highlighted the continued existence of others.JEL: G21, G23

Non solo e non tanto perché la scomposizione del centro urbano in una moltitudine di centri esterni (sostitutivi più che alternativi, ha determinato la crisi dell’urbanità storica – che ha costruito la città nella sua articolazione di spazi funzionalmente e figurativamente diversi. Quanto perché le zone periferiche, investite della creazione di nuove urbanità, si devono caricare anche della responsabilità di dar forma e senso alla città mediante la definizione del suo limite esterno. Gli interventi nelle periferie dovranno essere il punto di inizio per un ritorno alla città: rigenerata, sostenibile, funzionale, spazialmente densa e compatta. / It is time to speak of the suburbs again. Not only and not so much because fragmentation of the urban centre into a multitude of external “centres” (substitutes rather than alternatives, has determined a crisis in historic urbanism ‒ which is what divided the city into spaces that were functionally and figuratively different ‒ but because suburban areas, invested with the creation of new urbanity, must also assume the responsibility to shape and give sense to the city by defining its outer limit. Interventions in the suburbs must be the starting point for a return to the city: regenerated, sustainable, functional, spatially dense, and compact.

    Full Text Available Digital Materialism: Approaches and Perspectives in Media Studies This paper explores theoretical and methodological frameworks into the complex interdisciplinary field of Digital Materialism as media theory. From a starting point of the notion of “digital materiality”, as a core concept to develop an epistemological shift towards “material turn”, we aim to illustrate different approaches as new materialist paradigms, German media theory, Media Archaeology, Media ecologies, Software Studies and Marxist media theory. The so-called Digital Materialist Studies include a wide range of theories, which are sometimes in mutual opposition. However, overall these approaches help to re-evaluate the centrality of the material dimension of digital media in contemporary society. Finally, we indicate some possible theoretical evolutions of digital materialism. On the one hand, there are theories focused on highlighting the complexization and diversification of power relations through the study of some “lens” of digital materialities (Pötzsch 2017. On the other hand, we suggest the possibility of combining in a coherent theoretical framework the media archaeology studies of the Italian theorist Alberto Abruzzese in order to investigate the transition from old media to digital media by analyzing the material and symbolic conflicts that the media themselves incorporate.

    Full Text Available Il contributo analizza, in chiave geografica, le dinamiche che legano il turismo e il cinema a Verona, città meta consolidata di turismo urbano. Consapevoli che il mito di Giulietta e Romeo svolga un ruolo considerevole all’interno delle motivazioni che inducono il turista a soggiornare nella città veneta, risulta utile soffermarsi sulla funzione svolta dai film, di “antica” e recente realizzazione, nella conoscenza dei luoghi. In virtù delle sempre mutevoli richieste dei visitatori, pare interessante riflettere se sia “conveniente” per Verona, non tanto e non solo economicamente ma, soprattutto, in una logica di sostenibilità, continuare a proporre al turista il cliché della città degli innamorati o se non si debba, al contrario, pensare a nuove esperienze emozionali attraverso la promozione di itinerari le cui tappe non siano solo il balcone di Giulietta, la casa di Romeo, la tomba di Giulietta ma luoghi decisamente più veri quali le piazze storiche della città, i negozi tipici, i centri culturali. The paper analyzes, in geographical key, the dynamics that bind tourism and film in Verona, the city consolidated urban tourism destination. Aware that the myth of Romeo and Juliet plays a considerable role in the reasons for the tourist to stay in the Venetian city, it is useful to focus on the role played by "old" and recently shot films in the knowledge of the places. By virtue of the ever-changing demands of visitors, it seems interesting to consider whether it is “convenient” for Verona, not so much and not only economically but, above all, in a logic of sustainability, to continue to offer to the tourist the cliché of the city of lovers or if it is better to hink of new emotional experiences through the promotion of itineraries whose stages are not just Juliet's balcony, the house of Romeo, Juliet's tomb but places much more real as the historical squares of the city, the local shops and the cultural centers.

    Wyman, V.

    1990-01-01

    Contacts between the South Korean nuclear industry and a combined United Kingdom mission representing AEA Technology and British Nuclear Fuels Limited (BNFL) are reported. Prospects for entering the Korean market in two areas are perceived. The first is waste management and the second is the Safe Integral Reactor (SIR), an advanced pressurized water reactor design. AEA Technology and three collaborators have been promoting SIR as an inherently safe reactor design. Korean interest could be expressed in financial backing for the building of SIR stations in Korea and the opportunity could arise for BNFL to win fuel supply contracts. (UK)

  11. Energy prospects

    Lyall, K.

    1991-01-01

    The Business Council of Australia's study on Prospects for Improved Energy Efficiency and the Application of Renewable Energy Resources is summarised. The study estimates that replacement of all off-peak electric units in Australia with solar gas boosted systems would reduce electricity consumption for residential water heating by approximately 25% and almost halve carbon dioxide emissions resulting from residential water heating. Furthermore, substitution of all water heating units in Australia with solar gas systems would reduce total emissions by about 80%. The study concludes that while substitution on such a scale could not readily be achieved even within several decades, the estimates do indicate the significant benefits that might be realised by a long term program. 2 refs., 3 tabs

    During the last few years geochemical prospecting techniques have become common usage in the field of mineral deposit prospecting. The real scope of these methods lies in their use in the prospecting of large areas. The most promising use of the geochemistry and hydro-geochemistry of uranium is in heavily forested tropical territories, with few outcrops, where radiometry is strongly handicapped. (author) [fr

  14. Endogenous Prospect Theory

    OpenAIRE

    Schmidt, Ulrich; Zank, Horst

    2010-01-01

    In previous models of (cumulative) prospect theory reference-dependence of preferences is imposed beforehand and the location of the reference point is exogenously determined. This paper provides an axiomatization of a new specification of cumulative prospect theory, termed endogenous prospect theory, where reference-dependence is derived from preference conditions and a unique reference point arises endogenously.

  15. Psychophysiology of prospective memory.

    Rothen, Nicolas; Meier, Beat

    2014-01-01

    Prospective memory involves the self-initiated retrieval of an intention upon an appropriate retrieval cue. Cue identification can be considered as an orienting reaction and may thus trigger a psychophysiological response. Here we present two experiments in which skin conductance responses (SCRs) elicited by prospective memory cues were compared to SCRs elicited by aversive stimuli to test whether a single prospective memory cue triggers a similar SCR as an aversive stimulus. In Experiment 2 we also assessed whether cue specificity had a differential influence on prospective memory performance and on SCRs. We found that detecting a single prospective memory cue is as likely to elicit a SCR as an aversive stimulus. Missed prospective memory cues also elicited SCRs. On a behavioural level, specific intentions led to better prospective memory performance. However, on a psychophysiological level specificity had no influence. More generally, the results indicate reliable SCRs for prospective memory cues and point to psychophysiological measures as valuable approach, which offers a new way to study one-off prospective memory tasks. Moreover, the findings are consistent with a theory that posits multiple prospective memory retrieval stages.

    Full Text Available  La crisi dell’economia americana ha forti ripercussioni non solo sui paesi europei, ma sul mondo intero; le difficoltà di altri importanti paesi, come il Giappone e l’Argentina, già gravi, sono diventate ancora più gravi per la crisi americana. I paesi del Terzo Mondo mostrano andamenti molto differenziati: nei mercati in cui la presenza dell’America e di altri paesi industrializzati è indebolita dalla crisi, essi riescono a crescere anche più di prima, grazie soprattutto alle esportazioni dei beni di industrie tradizionali: per produrre tali beni usano tecniche che comportano un minor grado di meccanizzazione e una maggiore quota di lavoro diretto, e ciò consente una più ampia flessibilità dei prezzi, con la conseguenza che nei mercati internazionali la loro competitività migliora, specialmente in periodi di congiuntura negativa. Stimolati anche da una tale congiuntura vari paesi del Terzo Mondo stanno esercitando una pressione crescente per indurre i paesi industrializzati a eliminare gradualmente le protezioni – dazi e sussidi – erette a difesa delle loro agricolture; la via da seguire, però, non è questa: è la via degli aiuti organizzativi.  The crisis in the U.S. economy has a major impact not only on Europe but the whole world; the difficulties of other major countries, such as Japan and Argentina, already serious, have become even more serious for the American crisis. The Third World countries show very different trends: in the markets in which the presence of America and other industrialized countries has been weakened by the crisis, they are able to grow even more than before, thanks to exports of goods of traditional industries: to produce these assets using techniques involving a lesser degree of mechanization and a greater proportion of direct business, which allows greater flexibility in prices, with the result that their competitiveness in international markets improves, especially in times of economic downturn. Stimulated also by such a situation many Third World countries are putting increasing pressure to induce the industrialized countries to phase out protection - tariffs and subsidies - erected in defense of their agriculture;  the way forward, however, is this: the way of organizational aids.  JEL Codes: E44, G1, G18, G28

    2014-10-01

    Full Text Available The use of oblique imagery has become a standard for many civil and mapping applications, thanks to the development of airborne digital multi-camera systems, as proposed by many companies. The indisputable virtue of oblique photography lies in its simplicity of interpretation and understanding for inexperienced users allowing their use of oblique images in very different applications, such as building detection and reconstruction, building structural damage classification, road land updating and administration services, etc. We report an overview of the actual oblique commercial systems and the workflow for the automated orientation and dense matching of large image blocks. Perspectives, potentialities, pitfalls and suggestions for achieving satisfactory results are given too.

    Full Text Available In this article we propose to overlap aesthetic experience with medial experience, starting from the assumption that every aesthetic experience is always a medial experience. Adopting a naturalistic approach, in which we explain what we mean with the term naturalization, we suggest a partial review of the issue. First, we state that human natural language is a kind of technology, made possible by certain physical, cognitive and social features; this sort of biological technology must be considered as an underlying condition for aesthetic experience. Secondly, we suggest the importance of social relationships among various species, demonstrating the role played by this relationships in natural selection: a new perspective will emerge. Thirdly, we explain in more detail why aesthetic experience can be likened to medial experience; in doing so, we offer an epistemological comparison between evolutionary theory and Marshall McLuhan’s approach to media studies. Resulting comparison will offer an original definition of aesthetic experience which rises through the interaction engaged by our natural technologies interacting prosthetically with environment.

    Full Text Available This article addresses the theme of prejudice in relation to disability as a central aspect in the context of the issue of social exclusion in people with disabilities. Going beyond the analysis of prejudice in narrow cognitive terms, as a form of stereotype, its conceptualization presents itself as a result of pathological defense mechanisms. With this in mind, prejudice towards disability is re-read in light of massive defenses against not only diversity, but also against those who carry mental pain. The articles concludes with a reflection on the ways in which prejudice against disability can be fought in our society in order to promote genuine social change.

Also, the two inquiries brought up some important points for future development of research in this field.

  9. Worldwide prospects of uranium prospection and production

    International Nuclear Information System (INIS)

    Beaumont, Claude; Duval, B.C.; Sarcia, J.A.

    1978-01-01

    The reserves of uranium ores, at present known in the western world, at a mining price below 80 US dollars per kilo, permit the needs corresponding to the life of the existing reactors to be satisfied until 1988; the more expensive estimated resources taken into account would permit an extension beyond the end of the century. But the transition from available reserves and their renewal to the evaluated reserves necessitates from now a considerable prospecting effort. There are great geological possibilities to cover needs: beside the known types of deposits which give the present production, there exist numerous other prospects which appear of interest to underline; nevertheless, they require a certain amount of progress, other methods of detection such as the metal extractive processes which are not necessarily beyond the reach of science and techniques. Obstacles are due to the fact that the scrupules of ecologic necessities are often slightly inconsiderate, and that states intervene more and more in the extractive industry when the object is not to satisfy their own needs. Lastly, the uncertainty of the long market (breeder or not) risk to discourage the effort of investors [fr

    Until recently, MR examinations of the pancreas were limited by motion artifacts, vascular pulsatility and poor spatial resolution. Today, new techniques have been developed, which allow to overcome these problems and provide additional information such as selective images of biliary and pancreatic ducts and vascular structures. As a complement to baseline sequences, MR cholangiopancreatography images can be acquired, possibly integrated by functional examination after secretin administration. Finally, contrast-enhanced MR angiography opens new perspectives for vascular studies, particularly for the locoregional staging of pancreatic cancer. [Italian] Lo studio del pancreas con risonanza magnetica e' stato fino a pochi anni fa limitato dagli artefatti da movimento, da pulsatilita' vascolare e dalla ridotta risoluzione spaziale. Recentemente sono state sviluppate nuove tecniche che consentono da un lato di risolvere tali problemi e dall'altro di fornire informazioni aggiuntive, quali immagini selettive delle vie biliari e del dotto pancreatico e delle strutture vascolari. Come completamento all'esame di base si possono ottenere immagini di colangiopancreatografia con RM, eventualmente integrate da prove funzionali, rappresentate dall'iniezione di secretina. Infine, le nuove tecniche di angiografia con RM con mdc, nelle quali si effettua un'acquisizione durante la prima fase di passaggio arterioso o venoso dopo introduzione rapida del mdc a livello di una vena periferica, aprono nuove prospettive per lo studio vascolare, in particolare nella stadiazione loco-regionale dei processi neoplastici.

    A procedure of prospection of minerals (''carborne''). It is characterized to be rapid and low costly if a sufficiently dense highway network is available or if transit with a vehicle across the fields is possible. Instruments, methods and results that may be obtained are given. The detector, a scintillation counter, is mounted on the top of an appropiate car registering continuously the measured values. Subsequently data are put on cartography, obtaining thus the values of iso-radiactivity which determine the values of ''background'' and the favorable zones for pursuing prospection work by other methods. The application of the method to the zone of the Chihuidos, province of Neuquen, is described in details and the obtained conclusions are given. (author) [es

  19. The uranium market prospects

    International Nuclear Information System (INIS)

    Lloyd, R.

    1981-01-01

    A historical analysis of the uranium market points out the cyclical nature of the market and suggests that the spot price, exploration levels, and mill capacity utilization rate are dependent on economic factors. An examination of the current uranium market suggests that the effects of the forecasted surplus supply, the diminishing returns in exploration and the long lead times and high costs of development may mean that future production levels are uncertain. The general prospects for the uranium industry are also uncertain because of barriers to trade, environmental regulations and public opinion. The paper concludes that by the use of long term contracts, appropriate inventory policy and greater discussion between producers and consumers the prospects for the uranium market can be made more certain and further imbalances in demand and supply can be avoided.

    Pregeometry is a theory, first suggested by Sakharov in 1967, in which gravity is taken as a quantum effect of matter fields and in which Einstein's theory of general relativity for gravity appears as an approximate and effective theory at long distances. It is shown by reviewing the extensive developments of pregeometric theories of gravity for the last more than a decade that the original idea by Sakharov is really working. Many future prospects of the theories are discussed in some detail. (author)

    1999-01-01

    Health values are important components of medical decisions. Experimental data suggest that people value health in complex and dynamic ways. Prospect theory is a descriptive theory of choice that may accurately characterize how people assign values to health states. The authors first provide background on prospect theory and how it can be applied to health values. Next, they review the relevant health research and find mixed support for prospect theory. Last, they discuss implications of prospect theory for cost-effectiveness analysis. The application of prospect theory to health deserves further research because it may help clarify the link between health and values.

    CDF has enhanced its capabilities for b-physics with the installation of a silicon vertex detector (SVX), which provides precise 2-dimensional tracking. The SVX impact parameter (IP) resolution (∼ 13μm for P t > 10 GeV) is well suited to detecting displaced secondary vertices (SV) from b-hadron decays (cτ B ≅ 390μm). In this paper we show evidence of SV detection using the Ψ → μ + μ - sample, which is b-enriched, and describe some prospects of b physics opened by the SVX with 25 pb -1 , the goal integrated luminosity of present run

    The monograph by A.I.Kiselev, A.A. Medvedev and Y.A.Menshikov, Astronautics: Summary and Prospects, aroused enthusiasm both among experts and the public at large. This is due to the felicitous choice of presentation that combines a simple description of complex space matters with scientificsubstantiation of the sub­ jectmatter described. The wealth of color photos makes the book still more attractive, and it was nominated for an award at the 14th International Moscow Book Fair, being singled out as the "best publication of the book fair". The book's popularity led to a second edition, substantially revised and enlarged. Since the first edition did not sufficiently cover the issues of space impact on ecology and the prospective development of space systems, the authors revised the entire volume, including in it the chapter "Space activity and ecology" and the section "Multi-function space systems". Using the federal monitoring system, now in the phase of system engi­ neering, as an example, the authors consi...

    High temperature superconductor (HTS) wire is rapidly maturing into a working material being produced in ever larger quantities and being used in more significant demonstrations and prototypes. Conductor is now produced routinely in several hundred meter lengths with reproducible results. Current density has progressed to a level suitable for demonstration of many applications. Wire strength has improved and large prototypes fabricated or under consideration using HTS include Superconducting Magnetic Energy Storage (SMES), rotating electrical machines including synchronous ac and dc homopolar motors and drives, generators and condensers, underground transmission cables, utility distribution equipment such as transformers and current limiters, commercial processing applications such as magnetic separation, and specialty magnets such as high field inserts.

    1990-01-01

    The different climates of the past and model simulations of future climates convincingly indicate that the continuing emissions of greenhouse gases will lead to significant global warming and to changes in precipitation and other climatic variables. The projected changes in atmospheric composition and, consequently, in climatic conditions will be unique and more rapid than at any time in the past. The developing understanding of the chemical cycles controlling atmospheric composition and of the processes and behavior controlling the climate system can provide significant guidance about how the future climate will change. This chapter first summarizes the many scientific advances described in the preceding chapters that can help one better understand and describe the climate system and the resulting agricultural and hydrological impacts of these changes in climate. The chapter then draws from this understanding to outline the prospects for future climate

  8. Prospects at high energies

    I discuss some possibilities for neutrino experiments in the fixed-target environment of the SPS, Tevatron, and UNK, with their primary proton beams of 0.4, 0.9, and 3.0 TeV. The emphasis is on unfinished business: issues that have been recognized for some time, but not yet resolved. Then I turn to prospects for proton-proton colliders to explore the 1-TeV scale. I review the motivation for new physics in the neighborhood of 1 TeV and mention some discovery possibilities for high-energy, high-luminosity hadron colliders and the implications they would have for neutrino physics. I raise the possibility of the direct study of neutrino interactions in hadron colliders. I close with a report on the status of the SSC project. 38 refs., 17 figs

  9. Prospects for gauge theories

    International Nuclear Information System (INIS)

    Bailin, D.

    1980-01-01

    The author reviews the present status of the standard model of weak and electromagnetic interactions and of QCD and examines the likely avenues of future development. The most attractive possibility is that there is a ''grand unified theory'' (GUT) which describes all known interactions except gravity, and in which the only input energy scale is the Planck mass. The GUTs so far proposed share the deficiency that they offer no explanation of the (>=3) observed fermion generations. The author reviews the 'horizontal' symmetries invented to bring order to the fermion sector. Typically such theories have non-minimal Higgs content, so he reviews the processes whereby charged or neutral scalars may be found. The incorporation of supersymmetry into the gauge theory of strong, weak and electromagnetic interactions is another attractive prospect and he discusses briefly the attempts to do this and the likely experimental signatures of such a scheme.

  10. Oil price prospects

    International Nuclear Information System (INIS)

    Toalster, J.

    1992-01-01

    In this paper, four different, popular approaches to the analysis of oil price movements will be considered and an alternative method will be proposed. Whilst we await the development of a rigorous theoretical framework within which to evaluate the phenomenon of oil price movements some progress may be effected by an amalgam of approaches, with the traditional supply and demand model being supplemented by observations regarding political and social developments in particular countries or regions, together with an assessment of emerging and prospective technological achievements. In this way it should be possible to identify the critical influences at work, from which it should also be possible to select either the single most important variable or combination of variables, affecting the oil price. Moreover, it is my belief that the crucial variables influencing the oil price almost certainly, are more likely to be political and social, rather than economic. In this context and notwithstanding the fact that there is only a minimal level of surplus productive capacity in the world oil industry at present (perhaps 1-2 million b/d albeit rising rapidly), it is reasonable to conclude that oil prices will average around $18-19 a barrel for North Sea Brent in 1992 and 1993, with oscillations of $2-4 a barrel either side, rising slightly in 1994 to $19-20 a barrel and to $20-21 a barrel in 1995. Thereafter, the most likely outcome is for a rise in line with inflation (say $ a barrel/annum) with no prospect of an upward spike, because demand will be weaker than most commentators expect up to the year 2000, whilst OPEC oil supplies will be substantially higher than the consensus forecast.

  11. Location-based prospective memory.

    Science.gov (United States)

    O'Rear, Andrea E; Radvansky, Gabriel A

    2018-02-01

    This study explores location-based prospective memory. People often have to remember to do things when in a particular location, such as buying tissues the next time they are in the supermarket. For event cognition theory, location is important for structuring events. However, because event cognition has not been used to examine prospective memory, the question remains of how multiple events will influence prospective memory performance. In our experiments, people delivered messages from store to store in a virtual shopping mall as an ongoing task. The prospective tasks were to do certain activities in certain stores. For Experiment 1, each trial involved one prospective memory task to be done in a single location at one of three delays. The virtual environment and location cues were effective for prospective memory, and performance was unaffected by delay. For Experiment 2, each trial involved two prospective memory tasks, given in either one or two instruction locations, and to be done in either one or two store locations. There was improved performance when people received instructions from two locations and did both tasks in one location relative to other combinations. This demonstrates that location-based event structure influences how well people perform on prospective memory tasks.

  13. Endogenizing Prospect Theory's Reference Point

    OpenAIRE

    Ulrich Schmidt; Horst Zank

    2010-01-01

    In previous models of (cumulative) prospect theory reference-dependence of preferences is imposed beforehand and the location of the reference point is exogenously determined. This note provides a foundation of prospect theory, where reference-dependence is derived from preference conditions and a unique reference point arises endogenously.

    Whose preferences are to be used for cost-effectiveness analysis? It has been recommended that community preferences for health states are the most appropriate ones for use in a reference case analysis. However, critics maintain that persons are not able properly to judge a health state if they have not experienced the condition themselves. This problem is analyzed here in the framework of Prospect Theory. It can be argued that the differing reference points of patients and the general public are responsible for deviating results. In addition, we argue that risk attitudes with respect to health-related quality of life are an indicator of reference points. If patients and the general public refer to the same reference point, i.e., they have the same risk attitude, the hypothesis is that deviations no longer significantly differ. Evaluations of the health condition of tinnitus by 210 patients and 210 unaffected persons were compared. The Time Tradeoff and Standard Gamble methods were applied to elicit preferences. Risk attitude was measured with the question of whether participants would undergo a treatment that could either improve or worsen their health condition, both with an equal chance (five possible answers between "in no case" and "in any case"). Affected persons indicated significantly higher values for tinnitus-related quality of life according to the Standard Gamble method. The difference between Time Tradeoff values was less dramatic but still significant. In addition, nonaffected persons are more risk-averse than affected persons. However, differences in evaluations are not significant considering single risk groups (e.g., those who answered "in no case"). Prospect Theory is a reasonable framework for considering the question of whose preferences count. If this result can be generalized for other diseases as well, it allows the mathematical combination of "objective" evaluations by the general public with the illness experience of patients. These

  15. IPY Progress and Prospects

    Science.gov (United States)

    Carlson, D.

    2008-12-01

    We can summarize the IPY goals as: (a) make major advances in polar knowledge and understanding; (b) leave a legacy of new or enhanced observational systems, facilities and infrastructure; (c) excite a new generation of polar scientists and engineers, and (d) elicit exceptional interest and participation from polar residents, schoolchildren, the general public, and decision-makers, worldwide. This talk reports on the progress and prospects in each of those areas from an overall international view; separate talks will describe details of future researcher and the IPY outreach efforts. To achieve major advances in knowledge, IPY has entrained the intellectual resources of thousands of scientists, many more than expected, often from 'non- polar' nations, and representing an unprecedented breadth of scientific specialties; integration of those efforts across disciplines to achieve integrated system-level understanding remains a substantial challenge. Many national and international organizations prepare plans to sustain new and improved observational systems, but clear outcomes and the necessary resources remain elusive. International outreach networks gradually build breadth and strength, largely through IPY Polar Science Days and other internationally- coordinated IPY events. A new Association of Polar Early Career Scientists (APECS) devotes talent and energy to shaping the future of polar research. These activities and networks may, with time and with continued international coordination, achieve an exceptional level of interest and participation. In all areas, much work remains.

  16. Biotechnology: challenges and prospects

    Energy Technology Data Exchange (ETDEWEB)

    Sasson, A.

    1985-04-01

    Rapidly occurring technological breakthroughs in the wake of numerous discoveries in different fields, such as biochemistry, genetic engineering as well as cellular and molecular biology as described in this paper have a variety of industrial applications, and forcasts covering these and various other fields have been made. The emerging bio-industry, covering diverse industries, such as chemical, food, pharmaceutical, etc., as well as the domains of health, environmental protection and abatement of pollution present challenging prospects. Several biotechnology processes relating to bioenergy, fermentation, waste transformation, vaccines, etc. are of particular interest to the developing countries. The 'functioning systems' resulting from the breakthrouth in genetic engineering, entailing extraordinary refinement of analytical techniques and technological progress, pose the challenging task of harnessing them to the advantage of mankind. Providing effective legal protection, conducive to the development of biotechnologies-their innovative process and technological change-is a matter of serious concern, involving practical and economical considerations. Several other issues and questions, such as risk prevention and management of potential dangers and hazards in genetic recombination operation by way of safety regulations and necessary guidelines, questions relating to the clinical trials of the interferons-the wonder drug-as well as questions of professional ethics are raised by biotechnologies. Industry-funded research in biotechnology, where scientific and commercial imperatives are interlocked, has for instance, its repercussions on the traditional thrust of university system, specially the sanctity of autonomy for basic research.

  17. ATLAS Detector Upgrade Prospects

    International Nuclear Information System (INIS)

    Dobre, M

    2017-01-01

    After the successful operation at the centre-of-mass energies of 7 and 8 TeV in 2010-2012, the LHC was ramped up and successfully took data at the centre-of-mass energies of 13 TeV in 2015 and 2016. Meanwhile, plans are actively advancing for a series of upgrades of the accelerator, culminating roughly ten years from now in the high-luminosity LHC (HL-LHC) project, which will deliver of the order of five times the LHC nominal instantaneous luminosity along with luminosity levelling. The ultimate goal is to extend the dataset from about few hundred fb −1 expected for LHC running by the end of 2018 to 3000 fb −1 by around 2035 for ATLAS and CMS. The challenge of coping with the HL-LHC instantaneous and integrated luminosity, along with the associated radiation levels, requires further major changes to the ATLAS detector. The designs are developing rapidly for a new all-silicon tracker, significant upgrades of the calorimeter and muon systems, as well as improved triggers and data acquisition. ATLAS is also examining potential benefits of extensions to larger pseudorapidity, particularly in tracking and muon systems. This report summarizes various improvements to the ATLAS detector required to cope with the anticipated evolution of the LHC luminosity during this decade and the next. A brief overview is also given on physics prospects with a pp centre-of-mass energy of 14 TeV. (paper)

  18. Prospects of particle physics

    International Nuclear Information System (INIS)

    Meyer-Berkhout, U.

    1986-01-01

    Remarkable progress has been achieved in the last two decades in the field of particle physics. From the insight gained by the many experimental data, physicists derive a framework picture of matter on the sub-nuclear level, consisting of fundamental components which interact with each other in a defined and quantitatively detectable manner. The data now available allowed a quantum field theory of strong interactions to be set up for the first time, and a unified theory of electromagnetic and weak interaction. Particle physicists today take particular interest in the problem of whether the strong interaction might fit into an extended unified theory. Such a grand unified theory would have a far-reaching impact on the conceptual models both of the cosmic and sub-nuclear dimensions, and possibly lead to observable effects in domains of energy and mass which will be opened up for experiments by the new accelerator generation underway. Current activities throughout the world for constructing or projecting the new high-energy particle accelerators are outlined in the article, together with the prospects expected by particle physicists, and a look back on the history and achievements of this field of science.

    Full Text Available The body’s story is interwoven with the construction of social and individual identities, from gender issues. This review is meant to suggest tracks to deepen these issues in an interdisciplinary and multidimensional, with the aim to map historical, cultural, psychological and sociological route that the body has faced in modern Western society. The speech is rooted in historical hypothesis documented by Schettini in Il gioco delle parti which highlights those social and economic changes that characterize the transition between 800 and 900. The debate on the transvestism of the century opens to the medical discourse, psychological, psychoanalytic, sociological and legal. This is tackled by Valerio and Vitelli in Sesso e genere. Uno sguardo tra storia e nuove prospettive. At the end, the text of Putino, I corpi di mezzo, narrates the story of the body with references to feminism, biopower to biopolitics, race to come to the "subversive" of an emancipation "from itself" .

    Full Text Available Il paradigma della modernità, adottando il concetto di sviluppo come tema chiave, ha elaborato moltissime teorie del mutamento: qui sviluppo e crisi risultano necessariamente contrapposti sia sotto il profilo teorico che empirico. La complessità crescente delle società europee contemporanee mette in discussione la capacità interpretativa del mutamento che le coinvolge attualmente e suggerisce l’elaborazione di nuove prospettive che focalizzino il processo di trasformazione in corso piuttosto che soffermarsi sul risultato. Dopo aver sinteticamente inquadrato il concetto di sviluppo nell’ambito del paradigma della modernità l’articolo intende sostenere l’utilità di una prospettiva che considera congiuntamente crisi e sviluppo per analizzare il mutamento delle democrazie contemporanee.

    1985-01-01

    Modern prospecting is the systematic search for specified and generally ill-exposed components of the Earth's crust known as ore. This prospecting depends entirely on reliable, or scientific knowledge for guidance and for recognition of the search objects. Improvement in prospecting results from additions and refinements to scientific knowledge. Scientific knowledge is an ordered distillation of observations too numerous and too complex in themselves for easy understanding and for effective management. The ordering of these observations is accomplished by an evolutionary hierarchy of abstractions. These abstractions employ simplified descriptions consisting of characterization by selected properties, sampling to represent much larger parts of a phenomenon, generalized mappings of patterns of geometrical and numerical relations among properties, and explanation (theory) of these patterns as functional relations among the selected properties. Each abstraction is predicated on the mode of abstraction anticipated for the next higher level, so that research is a deductive process in which the highest level, theory, is indispensible for the growth and refinement of scientific knowledge, and therefore of prospecting methodology. ?? 1985 Springer-Verlag.

    One item on the agenda of future colliders is certain to be the Higgs boson. What is it trying to tell us? The primary objective of any future collider must surely be to identify physics beyond the Standard Model, and supersymmetry is one of the most studied options. it Is supersymmetry waiting for us and, if so, can LHC Run 2 find it? The big surprise from the initial 13-TeV LHC data has been the appearance of a possible signal for a new boson X with a mass ~750 GeV. What are the prospects for future colliders if the X(750) exists? One of the most intriguing possibilities in electroweak physics would be the discovery of non-perturbative phenomena. What are the prospects for observing sphalerons at the LHC or a future collider?

    In the era of prospective payment, arranging financing for hospital capital projects is expected to become even more complicated than under cost-based reimbursement systems. This article outlines the information needed for a bond issue in the prospective payment environment, defines the roles and duties of several external persons and organizations involved with planning a major capital financing, and provides an overview of the entire process. This article assumes for illustrative purposes that a tax-exempt bond issue is going to be used to finance a facility expansion. This method was chosen since over 70% of all major capital financing for hospitals use the tax-exempt bond as the principal vehicle for attracting the necessary debt to finance a major construction project. The tax-exempt bond issue also requires the most detail in documentation and legal provisions.

  8. Prospects for oil and gas

    2011-01-01

    It was five years ago, in January 2006, that Futuribles devoted a major special issue (no. 315) to energy prospects and the greenhouse effect. That was already a time of great concern about this question and several articles offered analyses of the gloomy prospects for the development of energy resources and the issues around climate change. Among these, an article by Jean Laherrere outlined the prospects for oil resources, showing the extent to which information in this area was disparate, unreliable and even questionable, being often highly political. As one of the more pessimistic writers on the question, Laherrere reminded us of the imminence of 'peak oil' (the prelude to a decline in global oil production) and the need to re-think our styles of consumption to adapt to a new age in which, as energy becomes scarcer, it will be increasingly expensive. Five years later, Jean Laherrere returns to the columns of Futuribles on the occasion of a new special issue on energy and the climate, to update us on the global prospects for oil and gas production. He begins by recalling how politically slanted and unreliable information in this area can be, depending on its source, the units of measurement employed etc. He stresses, too, that in the view of many experts peak oil was reached in 2006 and the situation is currently plateau-ing, just ahead of a decline in oil production (gradual or sudden, depending on whether measures of economic constraint are implemented). For its part, gas production should peak around 2025-2030. Jean Laherrere specifies what reserves remain, how these are currently exploited and marketed, and the prospects that ensue in the longer term (he also shows how wrong gas-price forecasts have been in the past). As he stresses, in conclusion, with both oil and gas we must be aware that the world does not have infinite resources and, since the alternatives do not allow us, at the moment, to make up for future energy-resource shortages, it is for

    All living systems are characterized by an S-shaped growth curve, representing a lag phase, a phase of exponential growth and a plateau. Nuclear medicine is no exception. In one sense, medical imaging modalities, such as plain film and contrast studies, computerized tomography (CT), ultrasound, digital subtraction angiography, conventional nuclear imaging, and PET, are competitive. They compete for space, funds, people, enthusiasm, and interest. For example, in the 1970s the use of radionuclide brain scans dropped sharply in hospitals when CT became available; ultrasound and nuclear medicine studies of the biliary system led to a significant decrease in the use of oral cholecystograpy and intravenous cholangiography. Some predict that nuclear magnetic resonance (NMR) and digital radiography may have a significant impact on CT scanning by 1990, because current NMR images are comparable in anatomic resolution to CT without bone artifacts and, especially important in the 1980s, without ionizing radiation. In the face of all this competition, the continued growth and well-being of the field of nuclear medicine will depend on the degree to which the field can adapt itself to the changing circumstances of medical practice and research in the 1980s. The forces that will shape the future of nuclear medicine will continue to come from both within and outside the field

    Full Text Available L'articolo si compone di due parti. Nella prima si espongono alcuni punti focali del dibattito sul rapporto tra glottodidattica e tecnologie digitali (dai dispositivi mobili ai software per la comunicazione, fino agli attuali socialnetwork. In particolare l’attenzione è rivolta sul fatto che la lingua della comunicazione digitale costituisce una varietà linguistica dal confronto con la quale l’insegnamento di una L2 non può ormai prescindere, e che le tecnologie digitali della comunicazione, se correttamente adottate fuori e dentro la classe, consentono di ridurre il confine tra apprendimento guidato e acquisizione spontanea di una lingua seconda. Filo conduttore della riflessione è il concetto di “competenza comunicativa digitale”, che si aggiunge alle componenti della competenza linguistico-comunicativa indicate dal Quadro Comune Europeo di Riferimento per le Lingue. Nella seconda parte del lavoro, dal taglio più didattico, si presenta una serie di strumenti e di esperienze di insegnamento/apprendimento della L2 con l’uso delle tecnologie digitali. In particolare ci si sofferma sulle opportunità offerte dal Web 2.0, simulando la creazione di una piattaforma per l’insegnamento/apprendimento dell’italiano L2 completamente online. Non si tratta di una semplice piattaforma per l’e-learning (o d-learning, ma di una vera e propria rete per l’insegnamento, l’apprendimento, la comunicazione e la formazione che trasforma il modo in cui si usa, si apprende e si insegna una L2. L2 on the Web. Digital perspectives for teaching italian to foreignersThe article consists of two parts. In the first we illustrate some focal points in the debate on the relationship between language teaching and digital technologies (from mobile devices to communication software and current social networks. In particular, we focus on the fact that the language of digital communication is a linguistic variety which L2 teaching can no longer ignore, and that digital communication technologies, if utilized properly both inside and outside the classroom, reduce the boundary between guided learning and the spontaneous acquisition of a second language. The underlying theme is the concept of “digital communicative competence”, added to linguistic and communicative competences indicated by the Common European Framework of Reference for Languages. In the second, more didactic part, is a set of tools and experiences regarding L2 teaching/learning using digital technologies. In particular, we focus on the opportunities offered by the Web 2.0, simulating the creation of a platform for online L2 teaching/learning. This is not just a platform for e-learning (or d-learning, but a real network for teaching, learning, communication and training that transforms the way one learns and teaches a L2.

    2014-09-01

    Full Text Available Il presidente della Federazione Nazionale degli Ordini Veterinari Italiani (FNOVI, Gaetano Penocchio, si pone alcune domande: "Chi siamo per il "mondo del lavoro"? Quanto ha bisogno di noi? Siamo preparati a rispondere o a stimolare la domanda di professionalità veterinarie? Come restare competitivi e come garantire nuovi sbocchi occupazionali?". Il nuovo Rapporto sulla professione medico veterinaria, che esce a 4 anni di distanza dal precedente ed è ancora curato da Nomisma, nasce proprio per dare risposta agli interrogativi di cui sopra, proponendosi come strumento informativo aggiornato per il mondo veterinario e per le Istituzioni, nonché come strumento di approfondimento su cui fondare ulteriori riflessioni. Il volume si focalizza soprattutto sui diversi ambiti occupazionali del medico veterinario e sulla dimensione prospettica al 2030 dei possibili scenari evolutivi della professione. Lo "sguardo demoscopico" del Rapporto non prescinde da un dato che deve far riflettere, ovvero che in Italia il rapporto fra popolazione e medici veterinari è (ancora il più alto d'Europa. In vent'anni i veterinari sono raddoppiati fino agli attuali 30.415 di cui il 77% liberi professionisti, quindi esposti al rischio di non avere una continuità lavorativa. Tutto questo, peraltro, nel pieno di spinte recessive che ciclicamente colpiscono il Paese e nel quadro di una crisi globale che si protrae dal 2007. Eppure il Rapporto mette in luce che il 27% delle esportazioni italiane è rappresentato da prodotti alimentari di origine animale e che il comparto della filiera agroalimentare, strettamente connesso alla professione medico veterinaria, ha tenuto contenendo il calo dei consumi alimentari. Una chiave per rilanciare la professione potrebbe essere, ad esempio, quella della specializzazione nell'ambito della sicurezza alimentare: un settore poco curato soprattutto in ambito universitario, come afferma il presidente della FNOVI che chiosa così: "La competenza è tale quando è applicata e si trasforma in sviluppo collettivo, agendo su dinamiche di mercato più virtuose e governance di pianificazione e controllo improntate ad una organizzazione pubblica ammodernata, guidata da una classe veterinaria con capacità gestionali, regolatorie e di analisi utili allo sviluppo di una catena alimentare che scorre veloce su ingranaggi leggeri in quanto sburocratizzati e affidabili in quanto fondati sulla più qualificata gestione del rischio."

    Full Text Available The paper explores the so called on-demand economy – i.e. the economic model based on the use of online platforms that ensure the immediate matching between a user in need of a good or a service and another who is able to share his/her assets, goods, skills, time - with specific reference to labour law.Through an analysis of the economic model behind this form of employment, the characteristics and conditions of the workers involved, and the regulatory framework, the Author focuses on the need to protect the workforce performing its services through these platforms.Following an overview of the main topics, the contribution considers the consequences of this economic pattern, which entails that a worker operates as an independent contractor and sees the companies managing the platform services as mere intermediaries.Three fundamental aspects are identified in relation to which the needs of workers' protection are analysed: economic security, reputation and training‏.The paper concludes by stressing the need for legislative action to regulate a form of employment that is gaining momentum in different national contexts, and offers an overview of the ways in which such intervention might take place.‏

    2003-10-01

    Full Text Available Un'efficace politica di gestione e conservazione del lupo deve contare su informazioni affidabili di presenza e consistenza a livello dei branchi locali; su larga scala, tali informazioni devono essere raccolte in forma sistematica, organica e coordinata e con tecniche meno costose e impegnative di quelle utilizzate a fini di ricerca. In quest'ottica, l'attivazione di un sistema integrato di monitoraggio del lupo su un territorio di oltre 654 km² ha rappresentato una priorità nell'ambito di un progetto Life della Regione Emilia-Romagna. Le tecniche, e i relativi protocolli di monitoraggio, sono stati quindi adottati in base a considerazioni logistiche, alla disponibilità di risorse, mezzi e personale (18 operatori fissi, tra tecnici e studenti, alla possibilità di effettuare repliche di campionamento annuali e stagionali. La standardizzazione dei protocolli su larga scala è stata promossa da workshop di formazione sia teorici sia dimostrativi sul campo, da prove di concordanza e scambio periodico delle aree di competenza tra gli operatori coinvolti. Dati invernali relativi a presenza, spostamenti, frequenza di marcatura, dimensione, composizione e coesione dei branchi e loro area frequentata, vengono raccolti tramite snow-tracking. L'area interessata è stata suddivisa in 15 settori all'interno dei quali sono stati individuati circuiti di rilevamento, percorsi a rotazione con racchette da neve a partire da 36-48 ore dopo l'ultima nevicata e con continuità per l'intera stagione invernale, lungo i quali intercettare le piste dei lupi nella neve. Nella stagione estiva, l'eventuale presenza di cucciolate, e la localizzazione dei rispettivi rendez-vous, è stata indagata con la tecnica del wolf-howling tramite campionamento sistematico sull'intera area. Stime del numero e della composizione dei branchi, e della loro localizzazione, vengono inoltre supportate dalla tipizzazione genotipica (Laboratorio di Genetica dell'INFS a partire da campioni fecali raccolti nell'intero arco annuale. Nel corso di due stagioni invernali (2001-02 e 2002-03 sono stati ricostruiti in totale 451 km di piste di lupi. Nell'estate 2002 sono state realizzate circa 3.574 emissioni (trials da 238 stazioni di emissione (0,43 stazioni per km² nel corso di 2 repliche stagionali. Nel 5,4 % delle stazioni si sono ottenute risposte, per un totale di 19 risposte, di cui il 57,8% da parte di cuccioli e cuccioli e/o adulti. Attualmente si stima quindi una presenza minima di 6 branchi nell'intera area di progetto, con riproduzione accertata in almeno 3 di questi. La dimensione media minima (±DS dei branchi nei mesi invernali è risultata di 3,6 (±0,73 lupi, per una densità minima sull'intera area di 2,7 lupi residenti/100 km². In una prospettiva di affinamento e ulteriore calibrazione delle tecniche di monitoraggio indiretto su larga scala, i risultati ottenuti vengono quindi discussi alla luce della loro portata nonché dei limiti interpretativi e delle difficoltà operative.

    Among ENEA (Italian National Agency for New Technologies, Energy, and the Environment) activities, one deals with analysis and strategies of environmental and scientific information. A questionnaire, created in collaboration with AIGA (Italian Environmental Journalist Association) and UGIS (Italian Scientific Journalist Association) and WWF has been realized. Purpose of the work was to check the level of sensitivity of the Italian journalists on environmental and scientific issues and to investigate the main obstacle facing to their professional activity.Environmental and scientific problems are usually not correctly perceived by the public. These problems, in fact, undergo a `closeness/distance` perception syndrome despite the fact that they are often presented and discussed in the media. The dichotomy may be explained according to the following phenomenology: 1. the existence of the problem is well known but the scientific and technological contest results to be of hard comprehension; 2. better and prolonged debating about the problem increments the attendance echo but simultaneously decrements the real understanding of it. The public opinion response to the diffusion of news related to environmental and scientific themes of no immediate understanding is of great concern; 3. media organizations are not always suited for dealing with the advanced matter of environmental and scientific information.

    A review of the geology of Baluchistan indicates that sedimentary rocks consisting of sandstones and conglomerates ranging from Paleocene to Miocene age were formed under the fluviatile conditions. The region underwent Late Cretaceous-Early Cenozic continent to continent collision resulting in varied metallogenic environments. Considering the criteria of favourability for the environments of uranium deposition, it is found that these rocks and the acidicigneous rocks of Cretaceous age are favourable for the occurrence of uranium. A radiometric prospecting programme is suggested to locate possible mineralization in the region. (author)

    Public fears over nuclear safety have led some within the nuclear community to investigate the possibility of producing inherently safe nuclear reactors; that is, reactors that are transparently incapable of producing a core melt. While several promising designs of such reactors have been produced, support for large-scale research and development efforts has not been forthcoming. The prospects for commercialization of inherently safe reactors, therefore, are problematic; possible events such as further nuclear reactor accidents and superpower summits, could alter the present situation significantly.

The focus of this article is on prospects for alternate fusion fuels as the author sees them relative to the other choices: increased numbers of coal plants, fission reactors, renewables, and D-T fusion. Discussion is limited on the consideration of alternate fusion fuels to the catalyzed deuterium-deuterium fuel cycle. Reasons for seeking an alternate energy source are cost, a more secure fuel supply, environmental impact and safety. The technical risks associated with development of fusion are examined briefly

    Prospect theory (PT) hypothesizes that people judge states relative to a reference point, usually assumed to be their current health. States better than the reference point are valued on a concave portion of the utility function; worse states are valued on a convex portion. Using prospectively collected utility scores, the objective is to test empirically implications of PT. Osteoarthritis (OA) patients undergoing total hip arthroplasty periodically provided standard gamble scores for three OA hypothetical states describing mild, moderate, and severe OA as well as their subjectively defined current state (SDCS). Our hypothesis was that most patients improved between the pre- and postsurgery assessments. According to PT, scores for hypothetical states previously > SDCS but now < SDCS should be lower at the postsurgery assessment. Fourteen patients met the criteria for testing the hypothesis. Predictions were confirmed for 0 patients; there was no change or mixed results for 6 patients (42.9 percent); and scores moved in the direction opposite to that predicted by PT for 8 patients (57.1 percent). In general, the direction and magnitude of the changes in hypothetical-state scores do not conform to the predictions of PT.

Originally, kenaf usage in Indonesia is still limited only for jute sacks material, which is then displaced by plastic sacks production. While at international scale, kenaf has been started to be developed as pulp material, polypropylene composite, fibreglass replacement, and particle board for automotive industry materials. Indonesia is a tropical country this condition which suitable for kenaf cultivation. However, research reports about kenaf potential usages are still few and limited in domestic level only. Whereas, Indonesian kenaf plant information is needed by international community to understand comprehensively about the potential of tropical plants. This article aims to provide an overview about kenaf cultivation potential and usages in Indonesia as well as the possibility of future development. Key words: kenaf, fibre, prospect, potential.

    1981-01-01

    Important applications for x- and γ-ray spectroscopy are found in prospecting, materials characterization, environmental monitoring, the life sciences, and nuclear physics. The specific requirements vary for each application with varying degrees of emphasis on either spectrometer resolution, detection efficiency, or both. Since no one spectrometer is ideally suited to this wide range of needs, compromises are usually required. Gas and scintillation spectrometers have reached a level of maturity, and recent interest has concentrated on semiconductor spectrometers. Germanium detectors are showing continuing refinement and are the spectrometers of choice for high resolution applications. The new high-Z semiconductors, such as CdTe and HgI 2 , have shown steady improvement but are limited in both resolution and size and will likely be used only in applications which require their unique properties

Internationally, studies have focused on a limited range of predictors or specific injuries. Although these studies provide useful insights, applicability to NZ is limited given the importance of NZ's unique macro-social factors, such as NZ's no-fault accident compensation and rehabilitation scheme, the Accident Compensation Corporation (ACC). (1) To quantitatively determine the injury, rehabilitation, personal, social and economic factors leading to disability outcomes following injury in NZ. (2) To qualitatively explore experiences and perceptions of injury-related outcomes in face-to-face interviews with 15 Māori and 15 other New Zealanders, 6 and 12 months after injury. Four geographical regions within NZ. Prospective cohort study with telephone interviews 1, 4 and 12 months after injury. 2500 people (including 460 Māori), aged 18-64 years, randomly selected from ACC's entitlement claims register (people likely to be off work for at least 1 week or equivalent). Telephone interviews, electronic hospital and ACC injury data. Exposures include demographic, social, economic, work-related, health status, participation and/or environmental factors. Primary: disability (including WHODAS II) and health-related quality of life (including EQ-5D). Secondary: participation (paid and unpaid activities), life satisfaction and costs. Separate regression models will be developed for each of the outcomes. Repeated measures outcomes will be modelled using general estimating equation models and generalised linear mixed models.

  1. Status and development of uranium prospection methods

    International Nuclear Information System (INIS)

    Barthel, F.

    1978-01-01

    In radiometric prospection, gamma measuring equipment is widely used. Simple instruments, so-called scintillometers, can only measure total radiation while spectrometers permit separate measurements of uranium, thorium, or calcium via daughter products of their decay chains. Depending on the target investigated, airborne, carborne, or footborne methods are employed. In radon prospection the gaseous decay product radon is measured as a sign of hidden uranium enrichment in ground air or water from springs. Due to its high solubility, uranium is well suited for geochemical prospection where uranium concentrations in bodies of water, river sediments, soil and rock types are determined. There is a trend in uranium prospection towards the discovery of hidden orifications. Novel techniques, e.g. airborne geochemistry, isotope chemistry, tracer element measurement, etc. are being tested with a view to their suitability for uranium prospection.

    Full Text Available Mohammad Rashid Shahidi Bonjar,1 Leyla Shahidi Bonjar2 1School of Dentistry, Kerman University of Medical Sciences, Kerman Iran; 2Department of Pharmacology, College of Pharmacy, Kerman University of Medical Sciences, Kerman, Iran Abstract: This hypothesis proposes a new prospective approach to slow the aging process in older humans. The hypothesis could lead to developing new treatments for age-related illnesses and help humans to live longer. This hypothesis has no previous documentation in scientific media and has no protocol. Scientists have presented evidence that systemic aging is influenced by peculiar molecules in the blood. Researchers at Albert Einstein College of Medicine, New York, and Harvard University in Cambridge discovered elevated titer of aging-related molecules (ARMs in blood, which trigger cascade of aging process in mice; they also indicated that the process can be reduced or even reversed. By inhibiting the production of ARMs, they could reduce age-related cognitive and physical declines. The present hypothesis offers a new approach to translate these findings into medical treatment: extracorporeal adjustment of ARMs would lead to slower rates of aging. A prospective “antiaging blood filtration column” (AABFC is a nanotechnological device that would fulfill the central role in this approach. An AABFC would set a near-youth homeostatic titer of ARMs in the blood. In this regard, the AABFC immobilizes ARMs from the blood while blood passes through the column. The AABFC harbors antibodies against ARMs. ARM antibodies would be conjugated irreversibly to ARMs on contact surfaces of the reaction platforms inside the AABFC till near-youth homeostasis is attained. The treatment is performed with the aid of a blood-circulating pump. Similar to a renal dialysis machine, blood would circulate from the body to the AABFC and from there back to the body in a closed circuit until ARMs were sufficiently depleted from the blood. The

    1995-01-01

    This paper first reviews briefly the status and plans for research in magnetic fusion energy and discusses the prospects for the tokamak magnetic configuration to be the basis for a fusion power plant. Good progress has been made in achieving fusion reactor-level, deuterium-tritium (D-T) plasmas with the production of significant fusion power in the Joint European Torus (up to 2 MW) and the Tokamak Fusion Test Reactor (up to 10 MW) tokamaks. Advances on the technologies of heating, fueling, diagnostics, and materials supported these achievements. The successes have led to the initiation of the design phases of two tokamaks, the International Thermonuclear Experimental Reactor (ITER) and the US Toroidal Physics Experiment (TPX). ITER will demonstrate the controlled ignition and extended bum of D-T plasmas with steady state as an ultimate goal. ITER will further demonstrate technologies essential to a power plant in an integrated system and perform integrated testing of the high heat flux and nuclear components required to use fusion energy for practical purposes. TPX will complement ITER by testing advanced modes of steady-state plasma operation that, coupled with the developments in ITER, will lead to an optimized demonstration power plant

    Full Text Available According to the multiprocess framework (McDaniel & Einstein, 2000, the cognitive system can support prospective memory (PM retrieval through two general pathways. One pathway depends on top-down attentional control processes that maintain activation of the intention and/or monitor the environment for the triggering or target cues that indicate that the intention should be executed. A second pathway depends on (bottom-up spontaneous retrieval processes, processes that are often triggered by a PM target cue; critically spontaneous retrieval is assumed to not require monitoring or active maintenance of the intention. Given demand characteristics associated with experimental settings, however, participants are often inclined to monitor, thereby potentially masking discovery of bottom-up spontaneous retrieval processes. In this article, we discuss parameters of laboratory PM paradigms to discourage monitoring and review recent behavioral evidence from such paradigms that implicate spontaneous retrieval in PM. We then re-examine the neuro-imaging evidence from the lens of the multiprocess framework and suggest some critical modifications to existing neuro-cognitive interpretations of the neuro-imaging results. These modifications illuminate possible directions and refinements for further neuro-imaging investigations of PM.

    According to the multiprocess framework (McDaniel and Einstein, 2000), the cognitive system can support prospective memory (PM) retrieval through two general pathways. One pathway depends on top–down attentional control processes that maintain activation of the intention and/or monitor the environment for the triggering or target cues that indicate that the intention should be executed. A second pathway depends on (bottom–up) spontaneous retrieval processes, processes that are often triggered by a PM target cue; critically, spontaneous retrieval is assumed not to require monitoring or active maintenance of the intention. Given demand characteristics associated with experimental settings, however, participants are often inclined to monitor, thereby potentially masking discovery of bottom–up spontaneous retrieval processes. In this article, we discuss parameters of laboratory PM paradigms to discourage monitoring and review recent behavioral evidence from such paradigms that implicate spontaneous retrieval in PM.

    The purpose of this study is to know the incidence rate of medication reconciliation at admission and discharge in patients of La Rioja and to improve the patient safety on medication reconciliation. An observational prospective study, part of the Joint Action PaSQ, Work Package 5, European Union Network for Patient Safety and Quality of Care. The study has taken into account the definitions of the Institute for Safe Medication Practices. Any unintended discrepancy in medication between chronic treatment and the treatment prescribed in the hospital was considered as a reconciliation error. A total of 750 patients were included, 9 (1.2%) of whom showed at least one discrepancy. The patients had a total of 3,156 mediations registered: 2,313 prescriptions (73.4%) showed no differences, while 821 prescriptions (26%) were intended discrepancies and 21 prescriptions (0.6%) unintended discrepancies were considered by the physician as reconciliation errors. A percentage of 1.2 of the patients, which represents 0.6% of the medicines (one in 166 medications registered) had reconciliation errors during their hospital stay. A proceeding has been implemented by means of the physician doing the medication reconciliation and reviewing it with the help of a medication reconciliation form. The medication reconciliation is a priority strategic objective to improve the safety of patients. Copyright © 2016 SECA. Published by Elsevier Espana. All rights reserved.

  9. Prospects of geothermal resource exploitation

    International Nuclear Information System (INIS)

    Bourrelier, P.H.; Cornet, F.; Fouillac, C.

    1994-01-01

    The use of geothermal energy to generate electricity has only occurred during the past 50 years by drilling wells in aquifers close to magmas and producing either dry steam or hot water. The world's production of electricity from geothermal energy is over 6000 MWe and is still growing. The direct use of geothermal energy for major urban communities has been developed recently by exploitation of aquifers in sedimentary basins under large towns. Scaling up the extraction of heat implies the exploitation of larger and better located fields requiring an appropriate method of extraction; the objective of present attempts in USA, Japan and Europe is to create heat exchangers by the circulation of water between several deep wells. Two field categories are considered: the extension of classical geothermal fields beyond the aquifer areas, and areas favoured by both a high geothermal gradient, fractures inducing a natural permeability at large scale, and good commercial prospects (such as in the Rhenan Graben). Hot dry rocks concept has gained a large interest. 1 fig., 5 tabs., 11 refs

    Félix, Sandra; Araújo, Joana; Pires, Ana Maria; Sousa, Ana Cláudia

    2017-08-01

    A green prospective based on the reuse of waste materials such as almond shells, orange peel and used cooking oil to manufacture soap is presented. In Portugal, thousands of tons of waste are generated from used cooking oil and production of nut shells' residues is growing every year. In addition, the high consumption of citrus fruits, oranges in particular, generates large amounts of citrus peel. Therefore, it is necessary to diversify reuse mechanisms of these wastes, in order to make them back into raw materials. Complying with this trend, this work was carried out by processing and grinding almond shells, treating used oil, processing orange peels and extracting limonene, formulating and producing soap, and performing an acceptance study of the final product. Results validated a high potential of the idea in the field of environmental education, so it can be replicated in practical classes. It can also be useful for waste management, and it can support the development of community projects on an ecological approach. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Following the formation of United Reprocessors (U.R.G.) in 1976 by British Nuclear Fuels Limited (B.N.F.L.) in the United Kingdom, the Commissariat a l'Energie Atomique (C.E.A.) in France and K.E.W.A. Kernbrennstoff-Wiederaufarbeitungs-Gesellschaft MBH (K.E.W.A.) in Germany, collaboration is now well established for the marketing of their reprocessing services for irradiated oxide fuel from thermal reactors. In addition collaboration in the continued evolution of the technology has progressed and an extensive research and development programme has been established, the results of which are exchanged between the shareholders. During 1976 the U.K. Government has given approval to B.N.F.L. to sign further contracts with foreign customers, subject to certain conditions. In France, the fuel cycle activities of the C.E.A. have been vested in a new company (Compagnie Generale Des Matieres Nucleaires (C.O.G.E.M.A.)) and their La Hague plant has commenced reprocessing operations on irradiated oxide fuel. In Germany, an agreement has been signed between K.E.W.A. and P.W.K. for the pre-project study for the proposed German plant. Against this background this paper reviews the present status of reprocessing by the shareholders of U.R.G. and the prospects for reprocessing

    2013-12-01

    Full Text Available Over the last few years, a new and interesting theory has located the port of the ancient city of Tharros (Central-Western Sardinia in the area of the Mistras lagoon, nowadays completely unsuitable for such a purpose for a number of reasons. This new perspective, if substantiated by research, would explain why the localization of the seaport of the city of Tharros has been so uncertain so far. In this paper, the author shows the results of underwater and terrestrial surveys carried out in the area of the lagoon in the last years. She compares them with geomorphologic and historical evidence in order to analyse and discuss the possibility that the past geographical traits of the region could have made it suitable for hosting an active port until the VI century AD.

    Full Text Available After several terrorist attacks against the United States and his Allies, the international community has found a way to stop the spreading of extremists and recruiting of terrorists. In the papers we emphasise the necessity of the international community in which each group (Legal Authority, intelligence organism, political and religious organisations play an important role, terrorist attacks are a threat for international peace and security, in fact it’s considered a crime against the world. We can call terrorist acts all those behaviours which purpose is to threaten the collectivity with criminal indiscriminate actions, directed not against single persons but against what these people represent, or if directed towards the person independently of his position in the society, aiming to strike terror and weaken the structures. In the first part of this article I have described several kinds of international terrorism referring to the actual Italian legislation against terrorism and the cooperation of Italy, in the international circle, against terrorism. In the second part I traced the principal components of the reformation of information services for the security of Italy and the new discipline of secret. In the third and last part I have delineated the juridical normative aspects concerning victims of terrorism.La communauté internationale, après plusieurs attaques terroristes contre les États-Unis et ses pays alliés, a adopté une ligne de prévention et de contraste aux conditions qui peuvent favoriser la diffusion de la propagande extrémiste et du recrutement des terroristes. Dans le texte on souligne la nécessité, de la part de la Communauté internationale, d’une approche intégrée, dans laquelle chaque composant (Autorité Judiciaire, Organes d’intelligence, Organisations politiques et religieuses joue un rôle fondamental. Un acte terroriste est une véritable menace à la paix et à la sûreté internationales, en effet il est considéré tout à fait un crime contre l’humanité. On peut définir comme terroriste toute action dont le but est celui d’inspirer de la terreur dans la communauté international avec des actions criminelles aveugles. C’est-à dire qu’avec ces actions terroristes on veut frapper non pas une personne mais ce qu’elle répresente dans la societé, ou bien inspirer de la terreur pour ébranler la confiance en l’ordre constitué pour en affaiblir les structures. Dans la première partie de l’article j’ai décrit les différents types de terrorisme international, en faisant allusion à l’actuel legislation italienne contre le terrorisme et à la cooperation de l’Italie, dans le domaine international, à la lutte contre le terrorisme. Dans la seconde partie j’ai esquissé les éléments principaux de la réforme des Services d’information pour la sûreté de la République italienne et la nouvelle discipline du secret.

    2012-05-01

    Full Text Available nsformations society has faced in the transition from modernity to postmodernity have shaken the traditional group dimensions, and thereby, personal identity itself. The stray of the sense of belonging, linked to the consideration of some cultural, linguistic, religious traditions as our own, not only prevents from understanding the world. It also hampers the possibility to internalize all those aspects of the experience of "belonging" which, when lost, become nothing more than fragments of an essentially uncertain and provisional world. Taking up some of the concepts of the subjectual group analysis theory of personality, the article proposes a reflection on why some recent anthropological changes may represent a threat in relation to the development of individual identity, with a special focus on the concept of dis-identity. It will therefore highlight the instability of identification dynamics and the connection of this weak spot to the development of new forms of psychopathology.After illustrating the fragility of the internalization process of the composing elements of individual identity, the article associates the partial shadowing of the intersubjective dimension with the emergence of new psychopathological figures.

If bank is a creator of deposits, bank liquidity management influences bank rates, but deposits (money tend to become endogenous. While, if bank operates as intermediary among competitive markets, either bank rates or deposits are endogenously determined, and monetary rates become the price that equilibrate banking activity. Official rate adjustments have only the function of signalling the new range of equilibrating rates to banking operators.  JEL Codes: E51, E52

    2015-01-01

    Full Text Available Accuracy in management and presentation of data is probably the most relevant feature that characterizes libraries catalogues in the wide universe of information available online. This characteristic, which originates from the basic need of organizing knowledge, requires a constant activity of control. Authority control is part of such an activity. This paper examines authority control of personal names, and how it is carried out. The first part shows the international standards and local codes that govern it: these are necessary to understand the activities that create the network of links and references of the data in a catalogue entry. This activity is also influenced by the management information system; the second part of the paper thus examines the Italian Sistema Bibliotecario Nazionale and specifically the library system of the University of Florence, through an analysis of procedures, workflows and monitoring activities. The third part points out the importance of verifying data and access points in databases and in the web itself, in addition to catalogues, in order to manage information in a uniform and shared way. This work aims at showing the topicality of controlling access points to information in order to avoid data proliferation, an event that ultimately produces ‘noise’ in the activities of information retrieval and data description. It also aims at stressing the importance of promoting correct information in the web within a set of sharing policies pursued by library cooperation systems, also through technologies currently offered by the web itself.

La distribuzione delle merci in città paga infatti in competitività quei problemi di cui è in parte responsabile: traffico, inquinamento, incidenti etc. Negli ultimi anni la sensibilità su questi aspetti di sostenibilità ambientale è cresciuta in maniera netta, e a livello europeo molta strada è stata fatta per predisporre le risposte più adeguate. Il progetto europeo CityLog, finanziato nell’ambito del Settimo Programma Quadro, vede oggi collaborare diciotto partner europei coordinati dal Centro Ricerche Fiat per migliorare la logistica urbana agendo lungo tre direttrici: •\tservizi telematici orientati alla logistica, per dare un contributo decisivo al miglioramento della pianificazione delle missioni utilizzando strumenti per il routing ottimizzato dei veicoli e il supporto informativo costante agli autisti dei veicoli; •\tsoluzioni a bordo veicolo, che rappresentano un fattore chiave per aumentare la flessibilità operativa di camion e furgoni; •\tunità di carico innovative, accuratamente progettate per essere utilizzate su veicoli diversi in missioni diverse. Ne deriva pertanto una famiglia di container compatti con un layout interno riconfigurabile così da poter essere utilizzati per scopi diversi.

Archeological finds teli us that the site of Equilum had already been inhabited in the Late Bronze, Iron and Roman Age. In the Middle Ages it became a bishop's see and a wealthy trading town. Its inhabitants were among the founders of Venice. The site of Equilum lies nowadays north of Jesolo Paese, in the area of the "Anti...

    Jojoba (Simmondsia chinensis) is a crop that might be cultivated profitably in the arid and semi-arid zones of certain cultivated profitably in the arid and semi-arid zones of certain developing countries. This report assesses the present state of research on the crop and gives an opinion as to its prospects of being of economic benefit to these areas. The report is divided into five sections. In Section 1 the plant and its natural habitats are described and current research and the problems to be overcome in cultivating the crop are outlined. In Section 2 the chemistry of jojoba and other waxes is discussed. In Section 3 consideration is given to the end-use potential of jojoba and an attempt is made to forecast the future market demand and price for jojoba oil, both as a liquid and as a solid wax. In Section 4 the economics of jojoba production are discussed in light of the findings in the earlier sections. Finally, in Section 5, the wider aspects of plant introductions are considered briefly and conclusions drawn regarding jojoba's potential and its future research needs. It will be essential to increase jojoba yield significantly before cultivation will be viable except on a small scale. A satisfactory mechanized harvesting system also needs to be developed. The market for jojoba oil at various levels of production is estimated at production of less than 1000 tons (pounds-sterling 5500- pounds-sterling 7700 per ton); production of 2000 to 5000 tons (pounds-sterling 900- pounds-sterling 950 per ton); and production up to 20,000 tons (pounds-sterling 500-pounds-sterling 600 per ton).

  11. Energy intensities: Prospects and potential

    1992-01-01

    In the previous chapter, the author described how rising activity levels and structural change are pushing toward higher energy use in many sectors and regions, especially in the developing countries. The extent to which more activity leads to greater energy use will depend on the energy intensity of end-use activities. In this chapter, the author presents an overview of the potential for intensity reductions in each sector over the next 10-20 years. It is not the author's intent to describe in detail the various technologies that could be employed to improve energy efficiency, which has been done by others (see, for example, Lovins ampersand Lovins, 1991; Goldembert et al., 1987). Rather, he discusses the key factors that will shape future energy intensities in different parts of the world, and gives a sense for the changes that could be attained if greater attention were given to accelerate efficiency improvement. The prospects for energy intensities, and the potential for reduction, vary among sectors and parts of the world. In the majority of cases, intensities are tending to decline as new equipment and facilities come into use and improvements are made on existing stocks. The effect of stock turnover will be especially strong in the developing countries, where stocks are growing at a rapid pace, and the Former East Bloc, where much of the existing industrial plant will eventually be retired and replaced with more modern facilities. While reductions in energy intensity are likely in most areas, there is a large divergence between the technical and economic potential for reducing energy intensities and the direction in which present trends are moving. In the next chapter, the author presents scenarios that illustrate where trends are pointing, and what could be achieved if improving energy efficiency were a focus of public policies. 53 refs., 4 figs., 2 tabs

    The future is uncertain because some forthcoming events are unpredictable and also because our ability to foresee the myriad consequences of our own actions is limited. Here we studied how humans select actions under such extrinsic and intrinsic uncertainty, in view of an exponentially expanding number of prospects on a branching multivalued visual stimulus. A triangular grid of disks of different sizes scrolled down a touchscreen at a variable speed. The larger disks represented larger rewards. The task was to maximize the cumulative reward by touching one disk at a time in a rapid sequence, forming an upward path across the grid, while every step along the path constrained the part of the grid accessible in the future. This task captured some of the complexity of natural behavior in the risky and dynamic world, where ongoing decisions alter the landscape of future rewards. By comparing human behavior with behavior of ideal actors, we identified the strategies used by humans in terms of how far into the future they looked (their "depth of computation") and how often they attempted to incorporate new information about the future rewards (their "recalculation period"). We found that, for a given task difficulty, humans traded off their depth of computation for the recalculation period. The form of this tradeoff was consistent with a complete, brute-force exploration of all possible paths up to a resource-limited finite depth. A step-by-step analysis of the human behavior revealed that participants took into account very fine distinctions between the future rewards and that they abstained from some simple heuristics in assessment of the alternative paths, such as seeking only the largest disks or avoiding the smaller disks. The participants preferred to reduce their depth of computation or increase the recalculation period rather than sacrifice the precision of computation.

  14. The prospect of conventional disarmament

    The prospect of conventional disarmament in Europe holds out great consequences not only for the continent but also for the entire world. The arms race both in its nuclear and conventional aspects has been the single most important element of the destabilizing factors in international relations since 1945. Though initially borne out of the ideological division of Europe and the consequent quest for strategic military superiority, it soon developed a technological momentum of its own, becoming more the cause than the effect of the distrust in the relationship of the two alliances. The issue of conventional weapons was raised for negotiations side by side with that of nuclear weapons when the United Nations took up the question of disarmament in 1946. Due, however, to the unforeseen and most dangerous advance in nuclear weaponry, the fear engendered shifted all attention at the multilateral level to nuclear weapons. Except in Europe where the Mutual and Balanced Force Reduction Talks in Central Europe were initiated, conventional weapons disarmament did not attract multilateral attention again until the First Special Session of the United nations General Assembly Devoted to Disarmament in 1978. The Final Document of the Special Session did accord highest priority to negotiations on nuclear weapons. However, it also affirmed that side by side with negotiations on nuclear weapons, the limitation and gradual reduction of armed forces and conventional weapons should be resolutely pursued within the framework of general and complete disarmament. States with the largest military arsenals, it was stated, had a special responsibility in pursuing conventional armaments reduction. Underscoring the central role of Europe further, the Final Document postulated that the achievement of a more stable situation at a lower level of military potential would contribute toward strengthening of security in Europe and constitute a significant step toward international peace and security

There is a connection between myths, fantasies, ideas, concepts and projects aimed at the exploration of outer space, the creation of cosmic humanity. A new and voluminous definition of cosmic humanity in the evolutionary paradigm is given. Cosmic humanity is (essence and 4 stages of evolution: 1. Humanity living on Earth, sensing, knowing, understanding its cosmic origin, relationship with the cosmos and cosmic destiny. 2. Humanity living on Earth, leading aerospace activity for the purposes of exploration and use of aerospace space (Heaven, Space for survival and development. 3. Humanity living on Earth and outside the Earth — in the solar system, preserving the Earth and mastering the Cosmos for survival and development. 4. Humanity, settled and living in the Cosmos. Now humanity is in the process of transition from the second to the third stage. In the process of this evolution, a complex transformation of man and society takes place. The problem-semantic field of cosmic humanity is described and its general model is presented. The meta-goal-setting is the justification of cosmic humanity with the application of the anthropic principle and its “active” super (post anthropic supplement: “Cosmic humanity has an evolutionary purpose to actively manage evolution: change man, humanity and the universe.” The evolution of the “cosmic dream”, goals and technologies of space activities is formalized in the form of a conceptual model. Challenges and negative trends are considered in connection with the crisis of space activity, criticism and attempts to limit the flights of people into space. The prototype of cosmic humanity, its basis and acting model is the cosmonauts’ community. The main

  16. Procreative beneficence and the prospective parent.

    2006-03-01

    Julian Savulescu has given clear expression to a principle-that of "procreative beneficence"-which underlies the thought of many contemporary writers on bioethics. The principle of procreative beneficence (PPB) holds that parents or single reproducers are at least prima facie obliged to select the child, out of a range of possible children they might have, who will be likely to lead the best life. My aim in this paper is to argue that prospective parents, just by dint of their being prospective parents, are in fact not obliged to act on PPB. That is, there is something about their filling the role of prospective parents that exempts them from selecting the child with the best life. I urge that it is more realistic to view prospective parents as bound by a principle of acceptable outlook, which holds that they ought not to select children whose lives will contain an unacceptable amount of suffering.

    Geophysical methods and apparatus for shallow engineering geophysical prospecting and mining related in-roadway geophysical prospecting are important research fields which has been studied for long time, unfortunately, little significant advancement has been made compared with the demand of engineering geology. The seismic imaging method and its corresponding equipment are viewed as the most hopeful choice for 0-50 m depth and are studied in this research systematically. The recording equipment CSA is made and the related in-situ data processing software is also developed. Field application experiment for shallow seismic prospecting has been finished, the results show that the CSA seismic imaging and its application technology are effective and practical for the engineering geophysical prospecting of 0-50 m depth, and can meet the demand of engineering geology investigation. Hence, the geophysical method and equipment, which can meet the demand for 0-50 m depth engineering geology investigation have been formed through this research. (authors)

    Full Text Available Determination of the perceptions of the prospective teachers for the Information and Communications Technology (ICT terms have a remarkable potential to provide input for technology integration plans and ICT trainings. Within this context, the purpose of this study is to discover the metaphors constructed by prospective teachers for the ICT terms. Data were gathered from 180 prospective teachers through survey. 977 valid metaphors constructed by the participants were grouped into conceptual categories for the six ICT terms. The most common conceptual categories are “developing and changing” for technology, “making life easy” for computers and search engines, “limitless and endless” for the Internet, “means of communication” for social networks, and “addictive items” for video games. Future research should concentrate on investigating the match and mismatches between intended use of the ICT tools and the perception of the prospective teachers.

    Prospect theory is widely viewed as the best available descriptive model of how people evaluate risk in experimental settings. According to prospect theory, people make decisions based on the potential value of losses and gains rather than the final outcome. People are risk-averse with respect to gains and risk-seeking with respect to losses, a phenomenon called ``loss aversion''. Despite of the fact that prospect theory has been well studied in behavioral economics at the theoretical level, there exist very few empirical research and most of them has been undertaken with micro-panel data. Here we analyze the trading activities of over 1.5 million members of an online financial trading community over 28 months, aiming to explore the large-scale empirical aspect of prospect theory. By analyzing and comparing the behaviour of ``winners'' and ``losers'', i.e., traders with positive or negative final net profit, we find clear evidence of the loss aversion phenomenon, an essence in prospect theory. This work demonstrates an unprecedented large-scale empirical evidence of prospect theory. It has immediate implication in financial trading, e.g., developing new trading strategies by minimizing the effect of loss aversion. It also provides opportunity to augment online social trading, where users are allowed to watch and follow the trading activity of others, by predicting potential winners based on their historical trading behaviour.

    Full Text Available Abstract Background Randomized, prospective trials involving multi-institutional collaboration have become a central part of clinical and translational research. However, data management and coordination of multi-center studies is a complex process that involves developing systems for data collection and quality control, tracking data queries and resolutions, as well as developing communication procedures. We describe DADOS-Prospective, an open-source Web-based application for collecting and managing prospective data on human subjects for clinical and translational trials. DADOS-Prospective not only permits users to create new clinical research forms (CRF and supports electronic signatures, but also offers the advantage of containing, in a single environment, raw research data in downloadable spreadsheet format, source documentation and regulatory files stored in PDF format, and audit trails. Results Feedback from formal and field usability tests was used to guide the design and development of DADOS-Prospective. To date, DADOS-Prospective has been implemented in five prospective clinical studies at our institution. Four of these studies are still in the CRF creation phase and one study has been entirely launched. Conclusion DADOS-Prospective has significant advantages over existing Web-based data collecting programs. At our institution, it has been demonstrated to be an efficient tool for prospective clinical studies.

    While first studies suggested that emotional task material may enhance prospective memory performance in young and older adults, the extent and mechanisms of this effect are under debate. The authors explored possible differential effects of cue valence on the prospective and retrospective component of prospective memory in young and older adults. Forty-five young and 41 older adults performed a prospective memory task in which emotional valence of the prospective memory cue was manipulated (positive, negative, neutral). The multinomial model of event-based prospective memory was used to analyze effects of valence and age on the two prospective memory components separately. Results revealed an interaction indicating that age differences were smaller in both emotional valence conditions. For older adults positive cues improved the prospective component, while negative cues improved the retrospective component. No main effect of valence was found for younger adults on an overt accuracy measure, but model-based analyses showed that the retrospective component was enhanced in the positive compared with the negative cue condition. The study extends the literature in demonstrating that processes underlying emotional effects on prospective memory may differ depending on valence and age.

    The kind of laser extreme light infrastructure (ELI) provides will usher in a class of experiments we have only dreamed of for years. The characteristics that ELI brings in include: the highest intensity ever, large fluence, and relatively high repetition rate. A personal view of the author on the prospect of harnessing this unprecedented opportunity for advancing science of extreme fields is presented. The first characteristic of ELI, its intensity, will allow us to access, as many have stressed already, extreme fields that hover around the Schwinger field or at the very least the neighboring fields in which vacuum begins to behave as a nonlinear medium. In this sense, we are seriously probing the 'material' property of vacuum and thus the property that theory of relativity itself described and will entail. We will probe both special theory and general theory of relativity in regimes that have been never tested so far. We may see a glimpse into the reach of relativity or even its breakdown in some extreme regimes. We will learn Einstein and may even go beyond Einstein, if our journey is led. Laser-driven acceleration both by the laser field itself and by the wakefield that is triggered in a plasma is huge. Energies, if not luminosity, we can access, may be unprecedented going far beyond TeV. The nice thing about ELI is that it has relatively high repetition rate and average fluence as compared with other extreme lasers. This high fluence can be a key element that leads to applications to high energy physics, such as gamma-gamma collider driver experiment, and some gamma ray experiments that may be relevant in the frontier of photo-nuclear physics, and atomic energy applications. Needless to say, high fluence is one of most important features that industrial and medical applications may need. If we are lucky, we may see a door opens at the frontier of novel physics that may not be available by any other means. (authors)

    Full Text Available Background: Neurocutaneous syndromes (NCS are a group of genetic disorders that produce a variety of developmental abnormalities of the skin along with an increased risk of neurological complications. Cutaneous manifestations usually appear early in life and progress with time, but neurological features generally present at a later age. There is a paucity of data regarding the evolution of skin lesions and their correlation with the central nervous system involvement in children. Aim: The primary objective was to track the course of skin lesions in various forms of NCS in the pediatric age group. Our secondary aim was to assess whether there was any predictive value of the lesions in relation to the neurological manifestations. Materials and Methods: This prospective longitudinal study was conducted at a tertiary care pediatric dermatology referral clinic of the Institute of Child Health, Kolkata, West Bengal. Children between the age group 0 and 12 years were included in the study on the basis of standard diagnostic criteria for different NCS, during the period from March, 2000 to February, 2004, and each of the enrolled cases were followed up for a duration of six years. Results: The study population comprised of 67 children (35 boys, 32 girls.The mean age of presentation was 33.8±27.8 months (range 10 days to 111 months. The various forms of NCS observed was neurofibromatosis 1(NF1 (n=33, tuberous sclerosis complex (TSC (n=23, Sturge Weber syndrome (n=6, ataxia telangiectasia (n=2, PHACE syndrome (n=1, incontinentia pigmenti (n=1, and hypomelanosis of Ito (n=1. The presentations were varied, ranging from predominantly cutaneous to primarily neurological, depending on the disease entity and age group concerned. There was a significant increase in the number of café au lait macules (CALMs with time (P=0.0002 in NF1, unlike that of hypopigmented macules of TSC (P=0.15.

    Shkuratov, Y.; Litvinenko, L.; Shulga, V.; Yatskiv, Y.; Kislyuk, V.

    Ukraine has launch vehicles that are able to deliver about 300 kg to the lunar orbit. Future Ukrainian lunar program may propose a polar orbiter. This orbiter should fill principal information gaps in our knowledge about the Moon after Clementine and Lunar Prospector missions and the future missions, like Smart-1, Lunar-A, and Selene. We consider that this can be provided by radar studies of the Moon with supporting optical polarimetric observations from lunar polar orbit. These experiments allow one to better understand global structure of the lunar surface in a wide range of scales, from microns to kilometers. We propose three instruments for the prospective lunar orbiter. They are: a synthetic aperture imaging radar (SAR), ground-penetrating radar (GPR), and imaging polarimeter (IP). The main purpose of SAR is to study with high resolution (50 m) the permanently shadowed sites in the lunar polar regions. These sites are cold traps for volatiles, and have a potential of resource utilization. Possible presence of water ice in the regolith in the sites makes them interesting for permanent manned bases on the Moon. Radar imaging and mapping of other interesting regions could be also planned. Multi-frequencies multi-polarization soun d ing of the lunar surface with GPR can provide information about internal structure of the lunar surface from meters to several hundred meters deep. GPR can be used for measuring the megaregolith layer properties, detection of cryptomaria, and studies of internal structure of the largest craters. IP will be a CCD camera with an additional suite of polarizers. Modest spatial resolution (100 m) should provide a total coverage or a large portion of the lunar surface in oblique viewing basically at large phase angles. Polarization degree at large (>90°) phase angles bears information about characteristic size of the regolith particles. Additional radiophysical experiments are considered with the use of the SAR system, e.g., bistatic radar

    Full Text Available Mohammad Rashid Shahidi Bonjar,1 Leyla Shahidi Bonjar2 1School of Dentistry, 2College of Pharmacy, Kerman University of Medical Sciences, Kerman, Iran Abstract: The present paper proposes a prospective auxiliary treatment for sepsis. There exists no record in the published media on the subject. As an auxiliary therapy, efficacious extracorporeal removal of sepsis-causing bacterial antigens and their toxins (BATs from the blood of septic patients is discussed. The principal component to this approach is a bacterial polyvalent antibody-column (BPVAC, which selectively traps wide spectrum of BATs from blood in an extracorporeal circuit, and detoxified blood returns back to the patient’s body. BPVAC treatment would be a device of targeted medicine. Detoxification is performed under supervision of trained personnel using simple blood-circulating machines in which blood circulates from the patient to BPVAC and back to the patient aseptically. BPVACs’ reactive sites consist of carbon nanotubes on which a vast spectra of polyvalent BATs-antibodies are bond to. The devise acts as a biological filter that selectively immobilizes harmful BATs from intoxicated blood; however, no dialysis is involved. For effective neutralization, BPVAC provides large contact surface area with blood. BPVAC approach would have advantages of: 1 urgent neutralization of notorious BATs from blood of septic patients; 2 applicability in parallel with conventional treatments; 3 potential to minimize side effects of the malady; 4 applicability for a vast range of BATs; 5 potential to eliminate contact of BATs with internal tissues and organs; 6 tolerability by patients sensitive to antiserum injections; 7 capability for universal application; 8 affectivity when antibiotic-resistant bacteria are involved and the physician has no or limited access to appropriate antibiotics; and 10 being a single-use, disposable, and stand-alone device. Before using it for clinical trials in

    This note discusses differences between prospect theory and cumulative prospect theory. It shows that cumulative prospect theory is not merely a formal correction of some theoretical problems in prospect theory, but it also gives different predictions. Experiments are described that favor cumulative

    1977-01-01

    After dealing briefly with the geochemical cycle of uranium in the earth's crust, and indicating the principal conditions under which different types of deposits are formed, the paper goes on to determine the uraniferous are of mainland Argentina (approximately 900000 km 2 ). Since evidence for the presence of uranium and other radioactive elements in many parts of the country has long been available, an attempt was made to systemize the existing information and classify the uraniferous sites so as to determine their temporal, spatial and genetic relationships with the different containing rocks. In addition, a study was made of the factors which contribute to the concentration of uranium in rocks which are accessible to prospecting (litho-stratigraphy, geological history, mettallogenic cycles, etc.). On the basis of these studies and considering the regional geology of Argentina, 21 ''regional environments'' were defined with varying degrees of probability of containing uranium; these environments will be submitted to long-term regional prospecting studies. It was necessary, however, to make a further sub-division into more homogeneous units with more clearly graded levels of priority, with the result that there are 65 ''prospecting units''. Each of these units, in order of priority, will be subjected to systematic prospecting. Exploratory work on a suitable scale will be carried out in the ''uraniferous'' districts of the ''prospecting units''. The main features of Argentine geology relating to the likelihood of uranium occurrences are briefly described, and maps of the large geotechtonic areas and the ''regional environments'' are included.

    Prospective math teachers need to develop positive adaptive attitudes toward mathematics that will enable them to continue learning despite having to deal with obstacles and difficulties. This research focuses on the resilience improvement of the prospective mathematic teachers after being treated using problem-based learning based on their basic knowledge on mathematic and their overall knowledge on math. This research used only one group for pre-test and post-test. The result of this research shows that there is improvement on prospective teachers’ resilience after they were given treatment using problem-based learning. One of the factors causing the resilience improvement of the prospective mathematic teachers is the instructions on students’ work sheet. In the instructions, stud ents were asked to write difficulties in solving math problems as well as write down the solution they take to overcome them. This research can be used as a reference for other researchers who want to do the same research related on students’ resiliency o n math and or math lecturers to improve the resilience of prospective teachers to be resilient teachers on math in the future.

  3. Prospect theory in the valuation of health.

    Moffett, Maurice L; Suarez-Almazor, Maria E

    2005-08-01

    Prospect theory is the prominent nonexpected utility theory in the estimation of health state preference scores for quality-adjusted life year calculation. Until recently, the theory was not considered to be developed to the point of implementation in economic analysis. This review focuses on the research and evidence that tests the implementation of prospect theory into health state valuation. The typical application of expected utility theory assumes that a decision maker has stable preferences under conditions of risk and uncertainty. Under prospect theory, preferences are dependent on whether the decision maker regards the outcome of a choice as a gain or loss, relative to a reference point. The conceptual preference for standard gamble utilities in the valuation of health states has led to the development of elicitation techniques. Empirical evidence using these techniques indicates that when individual preferences are elicited, a prospect theory consistent framework appears to be necessary for adequate representation of individual health utilities. The relevance of prospect theory to policy making and resource allocation remains to be established. Societal preferences may not need the same attitudes towards risks as individual preferences, and may remain largely risk neutral.

    2010-01-01

    Basic principles of geophysical methods to uranium prospect are briefly introduced, and the effects as well as problems in using those methods are analysed respectively. Combining with the increasing demand of uranium resources for Chinese nuclear power development and the higher requirements of geophysical techniques, the developing directions and the thoughts of geophysical techniques in uranium prospecting were proposed. A new pattern with producing, teaching and researching together is brought forward to develop advancing uranium prospecting key technologies and to break through technological bottlenecks depending on independent innovation. Integrated geophysical methods for prospecting uranium deposits are suggested. The method includes geophysical techniques as follows: gravity, magnetic, seismic, radioactive, remote sensing, and geochemical method in some proving grounds. Based on the experimental research, new uranium deposits prospecting models with efficient integrated geophysical methods can be established. (authors)

    Prospect theory is widely viewed as the best available descriptive model of how people evaluate risk in experimental settings. According to prospect theory, people are typically risk-averse with respect to gains and risk-seeking with respect to losses, known as the "reflection effect". People are much more sensitive to losses than to gains of the same magnitude, a phenomenon called "loss aversion". Despite of the fact that prospect theory has been well developed in behavioral economics at the theoretical level, there exist very few large-scale empirical studies and most of the previous studies have been undertaken with micro-panel data. Here we analyze over 28.5 million trades made by 81.3 thousand traders of an online financial trading community over 28 months, aiming to explore the large-scale empirical aspect of prospect theory. By analyzing and comparing the behavior of winning and losing trades and traders, we find clear evidence of the reflection effect and the loss aversion phenomenon, which are essential in prospect theory. This work hence demonstrates an unprecedented large-scale empirical evidence of prospect theory, which has immediate implication in financial trading, e.g., developing new trading strategies by minimizing the impact of the reflection effect and the loss aversion phenomenon. Moreover, we introduce three novel behavioral metrics to differentiate winning and losing traders based on their historical trading behavior. This offers us potential opportunities to augment online social trading where traders are allowed to watch and follow the trading activities of others, by predicting potential winners based on their historical trading behavior.

    Two studies are reported that investigate the applicability of prospect theory to college students' academic decision making. Exp. 1 failed to provide support for the risk-seeking portion of the fourfold pattern predicted by prospect theory but did find the greater weighting of losses over gains. Using a more sensitive dependent measure, in Exp. 2 the results of the first experiment were replicated in terms of the gain-loss effect and also found some support for the fourfold pattern in the interaction between probabilities and gain versus loss. The greatest risk-seeking was found in the high probability loss condition.

    2015-02-01

    Loneliness has been linked cross-sectionally to emotional skill deficits (e.g., Zysberg, 2012), but missing from the literature is a longitudinal examination of these relationships. The present study fills that gap by examining the prospective relationships between loneliness and emotional functioning in young adolescents in England. One hundred and ninety-six adolescents aged 11-13 years (90 females) took part in the study and completed the youth version of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT-YV) and the peer-related subscale of the Loneliness and Aloneness Scale for Children and Adolescents (LACA) at two time points, which were 10 months apart. Prospective associations were obtained for male and female adolescents separately using cross-lagged statistical techniques. Our results showed prospective links between understanding and managing emotions and loneliness for both females and males. Perceiving and using emotions were prospectively linked to loneliness in males only. Possible explanations and directions for future research are discussed.

  9. Pattern recognition applied to uranium prospecting

    Briggs, P L; Press, F [Massachusetts Inst. of Tech., Cambridge (USA). Dept. of Earth and Planetary Sciences

    1977-07-14

    It is stated that pattern recognition techniques provide one way of combining quantitative and descriptive geological data for mineral prospecting. A quantified decision process using computer-selected patterns of geological data has the potential for selecting areas with undiscovered deposits of uranium or other minerals. When a natural resource is mined more rapidly than it is discovered, its continued production becomes increasingly difficult, and it has been noted that, although a considerable uranium reserve may remain in the U.S.A., the discovery rate for uranium is decreasing exponentially with cumulative exploration footage drilled. Pattern recognition methods of organising geological information for prospecting may provide new predictive power, as well as insight into the occurrence of uranium ore deposits. Often the task of prospecting consists of three stages of information processing: (1) collection of data on known ore deposits; (2) noting any regularities common to the known examples of an ore; (3) selection of new exploration targets based on the results of the second stage. A logical pattern recognition algorithm is here described that implements this geological procedure to demonstrate the possibility of building a quantified uranium prospecting guide from diverse geologic data.

    Bayoumi, A M; Redelmeier, D A

    2000-01-01

    Individuals sometimes express preferences that do not follow expected utility theory. Cumulative prospect theory adjusts for some phenomena by using decision weights rather than probabilities when analyzing a decision tree. The authors examined how probability transformations from cumulative prospect theory might alter a decision analysis of a prophylactic therapy in AIDS, eliciting utilities from patients with HIV infection (n = 75) and calculating expected outcomes using an established Markov model. They next focused on transformations of three sets of probabilities: 1) the probabilities used in calculating standard-gamble utility scores; 2) the probabilities of being in discrete Markov states; 3) the probabilities of transitioning between Markov states. The same prophylaxis strategy yielded the highest quality-adjusted survival under all transformations. For the average patient, prophylaxis appeared relatively less advantageous when standard-gamble utilities were transformed. Prophylaxis appeared relatively more advantageous when state probabilities were transformed and relatively less advantageous when transition probabilities were transformed. Transforming standard-gamble and transition probabilities simultaneously decreased the gain from prophylaxis by almost half. Sensitivity analysis indicated that even near-linear probability weighting transformations could substantially alter quality-adjusted survival estimates. The magnitude of benefit estimated in a decision-analytic model can change significantly after using cumulative prospect theory. Incorporating cumulative prospect theory into decision analysis can provide a form of sensitivity analysis and may help describe when people deviate from expected utility theory.

    1988-01-01

    Remote sensing is a kind of very effective method which can be used in all stages of geological prospecting. Geological prospecting with remote sensing method must be based on different genetic models of ore deposits, characteristics of geology-landscape and comprehensive analysis for geophysical and geochemical data, that is, by way of conceptual model prospecting. The prospecting results based on remote sensing geology should be assessed from three aspects such as direct, indirect and potential ones

  8. Prospect theory, reference points, and health decisions

    Directory of Open Access Journals (Sweden)

    Alan Schwartz

    2008-02-01

    Full Text Available In preventative health decisions, such as the decision to undergo an invasive screening test or treatment, people may be deterred from selecting the test because its perceived disutility relative to not testing is greater than the utility associated with prevention of possible disease. The prospect theory editing operation, by which a decision maker's reference point is determined, can have important effects on the disutility of the test. On the basis of the prospect theory value function, this paper develops two approaches to reducing disutility by directing the decision maker's attention to either (actual past or (expected future losses that result in shifted reference points. After providing a graphical description of the approaches and a mathematical proof of the direction of their effect on judgment, we briefly illustrate the potential value of these approaches with examples from qualitative research on prostate cancer treatment decisions.

  10. Synchrotron radiation and prospects of its applications

    Energy Technology Data Exchange (ETDEWEB)

    Kulipanov, G; Skrinskii, A

    1981-04-01

    Current and prospective applications are described of synchrotron radiation resulting from the motion of high-energy electrons or positrons in a magnetic field and covering a wide spectral range from the infrared to X-ray. The advantages of the synchrotron radiation include a big source luminance, a small angular divergence, the possibility of calculating the absolute intensity and the spectral distribution of the radiation. Special storage rings are most suitable as a source. Synchrotron radiation is applied in X-ray microscopy, energy diffractometry, atomic and molecular spectroscopy, in the structural analysis of microcrystals, very rapid diffractometry of biological objects and crystals, and in Moessbauer spectroscopy. The prospective applications include uses in metrology, medicine, X-ray lithography, elemental analysis, molecular microsurgery, and in radiation technology.

  12. Geochemical prospecting for uranium and thorium deposits

    International Nuclear Information System (INIS)

    Boyle, R.W.

    1980-01-01

    A brief review of analytical geochemical prospecting methods for uranium and thorium is given excluding radiometric techniques, except those utilized in the determination of radon. The indicator (pathfinder) elements useful in geochemical surveys are listed for each of the types of known uranium and thorium deposits; this is followed by sections on analytical geochemical surveys based on rocks (lithochemical surveys), unconsolidated materials (pedochemical surveys), natural waters and sediments (hydrochemical surveys), biological materials (biogeochemical surveys) and gases (atmochemical surveys). All of the analytical geochemical methods are applicable in prospecting for thorium and uranium, particularly where radiometric methods fail due to attenuation by overburden, water, deep leaching and so on. Efficiency in the discovery of uranium and/or thorium orebodies is promoted by an integrated methods approach employing geological pattern recognition in the localization of deposits, analytical geochemical surveys, and radiometric surveys.

  15. What Prospects for the World Trading System?

    Directory of Open Access Journals (Sweden)

    Agnes Ghibuțiu

    2014-07-01

    Full Text Available New developments and dramatic changes are under way in the world trading system. This paper aims to take stock of the latest and most relevant developments and highlight the prospects for global trade governance. The focus is on three major issues, i.e. : (1 the outcome of the Ninth WTO Ministerial Conference in December 2013 in Bali (Indonesia and especially its significance for enhancing the multilateral trading system; (2 the accelerated pace and scale of negotiations on regional trade agreements (RTAs and their wider impact; and (3 the positive results of continued unilateral trade liberalization efforts, in contrast with the pervasiveness of crisis-related protectionist measures. The paper concludes that, despite improved prospects for multilateral trade liberalization following the last WTO Ministerial Conference, the world trading system is becoming more fragmented and less coherent, and also more uncertain, being increasingly driven by RTAs and a variable geometry approach to WTO trade agreements.

    Badescu, Viorel (ed.) [Bucharest Polytechnic Univ. (Romania). Candida Oancea Institute

    2013-11-01

    Recent research on Prospective Energy and Material Resources on Asteroids. Carefully edited book dedicated to Asteroids prospective energy and material resources. Written by leading experts in the field. The Earth has limited material and energy resources while these resources in space are virtually unlimited. Further development of humanity will require going beyond our planet and exploring of extraterrestrial resources and sources of unlimited power. Thus far, all missions to asteroids have been motivated by scientific exploration. However, given recent advancements in various space technologies, mining asteroids for resources is becoming ever more feasible. A significant portion of asteroids value is derived from their location; the required resources do not need to be lifted at a great expense from the surface of the Earth. Resources derived from Asteroid not only can be brought back to Earth but could also be used to sustain human exploration of space and permanent settlements in space. This book investigates asteroids' prospective energy and material resources. It is a collection of topics related to asteroid exploration, and utilization. It presents past and future technologies and solutions to old problems that could become reality in our life time. The book therefore is a great source of condensed information for specialists involved in current and impending asteroid-related activities and a good starting point for space researchers, inventors, technologists and potential investors. Written for researchers, engineers, and businessmen interested in asteroids' exploration and exploitation.

  13. Transparent meta-analysis of prospective memory and aging.

    Directory of Open Access Journals (Sweden)

    Bob Uttl

    Full Text Available Prospective memory (ProM refers to our ability to become aware of a previously formed plan at the right time and place. After two decades of research on prospective memory and aging, narrative reviews and summaries have arrived at widely different conclusions. One view is that prospective memory shows large age declines, larger than age declines on retrospective memory (RetM. Another view is that prospective memory is an exception to age declines and remains invariant across the adult lifespan. The present meta-analysis of over twenty years of research settles this controversy. It shows that prospective memory declines with aging and that the magnitude of age decline varies by prospective memory subdomain (vigilance, prospective memory proper, habitual prospective memory as well as test setting (laboratory, natural. Moreover, this meta-analysis demonstrates that previous claims of no age declines in prospective memory are artifacts of methodological and conceptual issues afflicting prior research including widespread ceiling effects, low statistical power, age confounds, and failure to distinguish between various subdomains of prospective memory (e.g., vigilance and prospective memory proper.

  14. Prospect relativity: how choice options influence decision under risk.

    Science.gov (United States)

    Stewart, Neil; Chater, Nick; Stott, Henry P; Reimers, Stian

    2003-03-01

    In many theories of decision under risk (e.g., expected utility theory, rank-dependent utility theory, and prospect theory), the utility of a prospect is independent of other options in the choice set. The experiments presented here show a large effect of the available options, suggesting instead that prospects are valued relative to one another. The judged certainty equivalent for a prospect is strongly influenced by the options available. Similarly, the selection of a preferred prospect is strongly influenced by the prospects available. Alternative theories of decision under risk (e.g., the stochastic difference model, multialternative decision field theory, and range frequency theory), where prospects are valued relative to one another, can provide an account of these context effects.

    2001-07-01

    Physical phenomena that occur in the solid part of the Earth are investigated by Solid Earth Geophysics together with problems related to the shape, location, and characteristics of the different parts that constitute the Earth. Repeated measurements lead the scientists to model the past evolution of the various processes as well as to forecast the future ones. Various disciplines refer to Solid Earth Geophysics, they are: Seismology, Gravimetry, Magnetometry, Geothermics, Geodesy, Geo electromagnetism, and Seismic Exploration. A special citation is due to Applied Geophysics, which are devoted to the identification of minerals, energetic and natural resources. The National Group of Solid Earth Geophysics was constituted in 1978 by CNR for promoting, developing, and coordinating researches related to Solid Earth Geophysics. The limited annual financial budget has conditioned the realisation of relevant multi-disciplinary projects. Nevertheless, important results were obtained in all different fields of Geophysics and were disseminated during the annual conference of the Group. A summary review of the main topics treated during the last conference is given here and some ideas for future research projects are presented. [Italian] La Geofisica della Terra Solida e' quella branca delle scienze e delle tecnologie che prende in considerazione dei fenomeni connessi con le caratteristiche fisiche della parte solida della Terra. La complessita' della costituzione della Terra e della sua evoluzione nel tempo implica che vengano prese in considerazione tutte le fenomenologie che si riescono a misurare e che costituiscono branche diverse della Geofisica: la Sismologia, la Gravimetria, la Magnetometria, la Geotermia, la Geodesia, il Geoelettromagnetismo, la Geofisica applicata. Ognuna di queste branche della Geofisica ha avuto in passato uno sviluppo quasi del tutto indipendente con collaborazioni o integrazioni dirtte ad obiettivi specifici, limitati anche nel tempo. Il Gruppo Nazionale di Geofisica della Terra Solida (GNGTS) e' stato istituito dal CNR, per iniziativa dei Comitati per le Scienze Fisiche e per le Scienze Geologiche ed ha avuto come principale scopo quello di avvicinare e far interagire i ricercatori non solo delle varie branche della Geofisica ma anche delle varie scuole che si erano sviluppate in Italia, di far conoscere e confrontare le metodologie e le tecniche sviluppate, di promuovere ricerche, seminari, convegni, in cui le varie realta' si potessero confrontare ed integrare, anche per una nuova o rinnovata conoscenza personale.

    Full Text Available Da oltre un ventennio, il tema della guerra da corsa e quello del commercio dei captivi nel Mediterraneo di età moderna, ad esso strettamente connesso, sono oggetto di rinnovato interesse da parte della storiografia internazionale. Soprattutto in Italia, Spagna e Francia (ma anche altrove, ricerche sistematiche hanno permesso di ricostruire diversi aspetti della schiavitù nel Mediterraneo di età moderna: modalità della cattura, condizioni di vita dei prigionieri, riscatti, conversioni. Non solo storici, ma anche antropologi, economisti, storici delle religioni e del diritto hanno dato il loro contributo alla ricerca, tradottosi in raccolte di saggi o in volumi monografici; tale abbondante produzione ha innanzitutto mostrato chiaramente come la guerra da corsa e il commercio dei captivi abbiano rappresentato a lungo un elemento cruciale della storia dei paesi che si affacciano sul Mediterraneo, dal medioevo all’età moderna, giungendo fino ai primi decenni del secolo XIX. Nelle prossime pagine proveremo a ricostruire, a grandi linee, l’evoluzione del dibattito storiografico sull’argomento, in modo da far emergere le questioni ancora aperte e di individuare nuovi possibili percorsi di indagine, che sfruttino in particolare le serie documentarie ancora scarsamente utilizzate o meritevoli di ulteriori ricerche.

    The break-up of the Soviet Union in the early 1990s opened the door for the international oil companies to explore and develop the Caspian Sea's hydrocarbons resources. The full utilisation of this wealth, however, has been hindered by disagreement over the ownership of the basin and the choice of export routes. Another important obstacle is the troubled relationship between the United States and Iran. [Italian] Il crollo dell'Unione Sovietica nei primi anni '90 ha consentito alle compagnie petrolifere internazionali di esplorare e sviluppare le risorse di idrocarburi del Mar Caspio. Il disaccordo sulla proprieta del bacino e sulla scelta delle rotte di esportazione ha tuttavia impedito il pieno sfruttamento di questa ricchezza. Un altro importante ostacolo e dato dalle difficili relazioni tra Stati Uniti e Iran.

    L'articolo si propone di esaminare il significato, il ruolo e le implicazioni di alcuni approcci utilizzati nella gestione della biblioteca digitale.

    L'innovazione nella gestione delle risorse online e il miglioramento della loro interoperabilità si può ottenere con una normalizzazione degli schemi di metadati attraverso l'uso di standard interoperabili e vocabolari internazionali e condivisi, e con l'arricchimento dato da ontologie e linked data, che sono alla base delle riflessioni sul web semantico e sulla costruzione di livelli semantici sulle descrizioni dei metadati.

    Attraverso l'esame di alcune metodologie innovative di rappresentazione dell'informazione (LODe-BD, SWAP, l'articolo mostra alcune modalità di creazione della conoscenza in ambiente digitale, con particolare riferimento ai dati bibliografici.

    The article sets out to investigate the meaning, role and implications of some information management approaches used in Digital Library practice. A greater focus on innovation in managing online resources and on improving their interoperability can be achieved by normalizing metadata schemas through interoperable standards, world-wide accepted controlled vocabularies as well as by their enrichment through qualitatively constructed ontologies and linked data, which are key to the expansion of the semantic reasoning on the web through building and connection of additional semantic layers on top of metadata descriptions. Reviewing some innovative methods of information representation (LODe-BD, SWAP, the paper tries to lead the reader to discover some new ways of knowledge creation in digital information environment, in particular what concerns digital bibliographic records.

    Baker, Samuel L.; Kronenfeld, Jennie J.

    1990-01-01

    South Carolina Medicaid implemented prospective payment by diagnosis-related group (DRG) for inpatient care. The rate of complications among newborns and deliveries doubled immediately. The case-mix index for newborns increased 66.6 percent, which increased the total Medicaid hospital expenditure 5.5 percent. Outlier payments increased total expenditure further. DRG distribution change among newborns has a large impact on spending because newborn complication DRGs have high weights. States adopting a DRG-based payment system for Medicaid should anticipate a greater increase in case mix than Medicare experienced. PMID:10113463

  10. Prospects of the surfatron laser plasma accelerator

    International Nuclear Information System (INIS)

    Katsouleas, T.; Joshi, C.; Mori, W.; Dawson, J.M.

    1983-01-01

    The surfatron concept is proposed as a possible solution to the problem of staging in the laser-plasma beat wave accelerator scheme. Prospects of a 100 GeV particle accelerator based on the surfatron concept are explored. Finite angle optical mixing appears to be a promising solution for drastically reducing the width of the plane wave, thereby, making the required laser power and the device size realizable for a proof-of-principle experiment. Our conclusions are based mainly on analytical theory and one-dimensional particle simulations

  12. Application of solar chargers to prospection instruments

    International Nuclear Information System (INIS)

    Caille, G.

    1960-01-01

    The use of conventional batteries has certain disadvantages, and for this reason high-voltage batteries have been gradually replaced in all prospection instruments by transistor supply systems, using less cumbersome sources of energy. All the same low voltages are still necessary, and in hot or damp countries the use of these batteries leads to consumptions out of all proportion to the services rendered. This is why the use of solar energy possesses real advantages. After a brief review of the basic ideas on semiconductors, this article describes a selenium solar battery which was developed by the Westinghouse brakes and signals society. (author) [fr

  13. Coal industry - problems and prospects. [United Kingdom

    Energy Technology Data Exchange (ETDEWEB)

    Siddall, N

    1984-01-01

    Presidential Address by Sir Norman Siddall is presented which considers the problems and prospects facing the UK coal industry. The range of changes which business management is subject to are outlined together with the coal industry's response to these changes. Fluctuations in the energy market and the economy have resulted in a customer orientated approach to marketing, and improved efficiency throughout the industry. New technology has increased the efficiency of some aspects of operations but at the some time developments in the areas of industrial relations and public accountability have limited management's ability to respond to changes in the commercial environment.

  16. A prospect theory perspective on terrorism

    Directory of Open Access Journals (Sweden)

    Cind Du Bois

    2017-06-01

    Full Text Available This paper presents a new approach for the study of terrorist behaviour and argues that a framework based on Prospect Theory can provide novel, useful insights into the understanding of the terrorist mind-set. Such a framework allows different pathways to become a terrorist and although individual decisions are studied, the model also takes into account environmental factors. By changing these environmental factors and/or framing the choice differently, PT provides insights as to how the terrorist group and/or a charismatic leader can influence the individual’s whether or not to turn to terrorism.

  17. Panel discussion on prospects for fusion power

    International Nuclear Information System (INIS)

    Sheffield, J.

    1986-01-01

    Although substantial progress is made every year in fusion research, the projected time to realize the ultimate goal of commercial fusion always seems to be 25 to 30 years away. This shifting schedule reflects the underlying difficulty of developing fusion. Every new technology improves the prospects for success, yet as each fusion mountain is scaled, it serves mainly to bring a better view of the next mountain. Two questions are considered: (1) why are so many configurations studied, and (2) what constitutes an economic power density

  18. Development environmental attitude of prospective science teachers

    Iqbal, H.M.

    2000-01-01

    Since the last three decades or so, we have witnessed the growing concern of human beings, all over the world, to adopt measures to conserve and preserve environment of the planet earth, because the same has been threatened by human activity and by way of our unparalleled intervention in the otherwise balanced environment. This awareness and concern has emerged as a need of incorporating environmental Issues into the normal curricula, so that we can educate the young generation to become informed decision-makers of the future. UNESCO and UNEP have advocated (since the last three decades) to teach environmentalised science to students. In Pakistan, there have been attempts to change curricula in accordance with the need of the time. Teachers need new kinds of skills, attitudes and commitment to teach science in an environmentalised fashion. This article discusses the impact of a semester-course on change in environmental attitudes of prospective science-teachers. A pre-test, post-test method was used to ascertain any change in environmental attitude of prospective science-teachers, after studying the environmental education course. It has been shown that there was a change in the environmental attitude of science-teachers as a result of the one-semester course, but the change or the level of attitude was not substantial or satisfactory. There seems to be a need of adopting a comprehensive approach to environmental education, and introducing teaching of environmental concepts at a very early age. (author)

    1986-01-01

    In 1953, President Eisenhower announced the U.S. ''Atoms for Peace'' program. After slightly more than 30 years, there are in operation, under construction or on order more than 400,000 MW of commercial nuclear power generation capacity located in 35 nations, representing a total investment around a trillion U.S. dollars. The situation is noteworthy in terms of the rate of technical development, deployment and transfer, the magnitude of the financial investment, economic benefits, the favorable impact on public health and safety, and the usual and positive character of cooperation among all concerned. The fundamentals of nuclear power generation with regard to economics, safety and environmental impact are likely to favor the increased use of nuclear power. The future prospect of the nuclear power in the U.S. also will be clarified positively. In many ways, U.S. commercial nuclear power continues to benefit from the Navy nuclear propulsion program. The prospect of supply demand situation in the conversion, enrichment and fabrication of uranium fuel is explained. The amount of spent fuel arising in OECD countries and their storage capability up to 2000 are shown, and the storage capability projected is well in excess. (Kako, I.)

    Full Text Available The potential impact of breast cancer-related lymphedema (LE is quite extensive, yet it often remains under-diagnosed until the later stages. This project examines the effectiveness of prospective surveillance in post-surgical breast cancer patients. A retrospective analysis of 49 out of 100 patients enrolled in a longitudinal prospective study at a Midwestern breast center evaluates: (1 time required for completion of bilateral limb measurements and Lymphedema Breast Cancer Questionnaire (LBCQ; (2 referral to LE management with limb volume increase (LVI and/or LBCQ symptoms; and (3 cost of LE management at lower LVI (≥5%–≤10% versus traditional (≥10%. Findings revealed a visit timeframe mean of 40.3 min (range = 25–60; 43.6% of visits were ≤30-min timeframe. Visit and measurement times decreased as clinic staff gained measurement experience; measurement time mean was 17.9 min (range = 16.9–18.9. LBCQ symptoms and LVI were significantly (p < 0.001 correlated to LE referral; six of the nine patients referred (67% displayed both LBCQ symptoms/LVI. Visits with no symptoms reported did not result in referral, demonstrating the importance of using both indicators when assessing early LE. Lower threshold referral provides compelling evidence of potential cost savings over traditional threshold referral with reported costs of: $3755.00 and $6353.00, respectively (40.9% savings.

  1. Roboethics: Fundamental Concepts and Future Prospects

    Directory of Open Access Journals (Sweden)

    2018-06-01

    Full Text Available Many recent studies (e.g., IFR: International Federation of Robotics, 2016 predict that the number of robots (industrial, service/social, intelligent/autonomous will increase enormously in the future. Robots are directly involved in human life. Industrial robots, household robots, medical robots, assistive robots, sociable/entertainment robots, and war robots all play important roles in human life and raise crucial ethical problems for our society. The purpose of this paper is to provide an overview of the fundamental concepts of robot ethics (roboethics and some future prospects of robots and roboethics, as an introduction to the present Special Issue of the journal Information on “Roboethics”. We start with the question of what roboethics is, as well as a discussion of the methodologies of roboethics, including a brief look at the branches and theories of ethics in general. Then, we outline the major branches of roboethics, namely: medical roboethics, assistive roboethics, sociorobot ethics, war roboethics, autonomous car ethics, and cyborg ethics. Finally, we present the prospects for the future of robotics and roboethics.

  2. Expression of future prospective in indirect speech

    Bodnaruk Elena Vladimirovna

    2015-03-01

    Full Text Available The article analyzes the characteristics and use of grammatical semantics and lexical and grammatical means used to create future prospects in double indirect discourse. The material for the study were epic works by contemporary German writers. In the analysis of the empirical material it has been pointed out that indirect discourse has preterial basis and is the kind of most frequent inner speech of characters. The most widely used form with future semantics in preterial indirect speech is conditional I, formally having a conjunctive basis, but is mostly used with the indicative semantics. Competitive to conditional I in indirect speech is preterial indicative. A characteristic feature of the indirect speech is the use of modal verbs, which, thanks to its semantics is usually referred as an action at a later term, creating the prospect of future statements. The most frequent were modal verbs wollen and sollen in the form of the preterite, more rare verbs were m ssen and k nnen. German indirect speech distinguishes the ability to use forms on the basis of conjunctive: preterite and plusquamperfect of conjunctive. Both forms express values similar to those of the indicative. However, conjunctive forms the basis of the data shown in a slightly more pronounced seme of uncertainty that accompanies future uses of these forms in indirect speech. In addition, plusquamperfect conjunctive differs from others by the presence of the seme of completeness.

    In Malaysia, thorium exists in minerals and rare earth elements production residue. The average range of thorium content in Malaysian monazite and xenotime minerals was found about 70,000 and 15,000 ppm respectively. About 2,636 tonnes of Malaysian monazite was produced for a period of 5 years (2006-2010) and based on the above data, it can be estimated that Malaysian monazite contains about 184.5 tonnes of thorium. Although thorium can become a major radiological problem to our environment, but with the significant deposit of thorium in Malaysian monazite, it has a prospect as a future alternative fuel in nuclear technology. This paper will discuss the thorium issues in Malaysia especially its long term radiological risks to public health and environment at storage and disposal stages, the prospect of exploring and producing high purity thorium from our rare earth elements minerals for future thorium based reactor. This paper also highlights the holistic approach in thorium recovery from Malaysian rare earth element production residue to reduce its radioactivity and extraction of thorium and rare earth elements from the minerals with minimum radiological impact to health and environment.

    Full Text Available Forestry generates in all production segments a lot of waste which is a potential power source and an opportunity for electricity generation by the use of this material. Therefore, this study represents the construction of future scenarios for the power generation sector from alternative and renewable sources in the region of Vale do Taquari and Alto da Serra do Botucaraí, in the Northern-Central region of the Stat of Rio Grande do Sul, aiming for the application of waste and by-products from forestry present in a intensive and tendentious way in economic activities within the region. By way of prospective scenarios, one will be able to observe which events are impactful on the viability of an environmental project for recovery of forestry waste to generate electricity in the region. Thereby, we used the method described by Grumbach (2000, a methodology that prospects scenarios from the participation of experts, who collaborated analyzing and proposing events that impact as strengths and weaknesses, opportunities and threats and their interrelationships. Also, it was evident the degree of influence and dependence between the events, which create a matrix of cross impacts. Moreover, possible future scenarios have been constructed and analyzed for demonstrating that the study area has potential events that could serve as alternatives to the sector. However, no ideal scenario has been identified for the next five years, a fact that is due to the large amount of adverse events in six out of the ten final events.

    2007-01-01

    Purpose: To report results from two clinical trials evaluating helical tomotherapy (HT). Methods and Materials: Patients were enrolled in one of two prospective trials of HT (one for palliative and one for radical treatment). Both an HT plan and a companion three-dimensional conformal radiotherapy (3D-CRT) plan were generated. Pretreatment megavoltage computed tomography was used for daily image guidance. Results: From September 2004 to January 2006, a total of 61 sites in 60 patients were treated. In all but one case, a clinically acceptable tomotherapy plan for treatment was generated. Helical tomotherapy plans were subjectively equivalent or superior to 3D-CRT in 95% of plans. Helical tomotherapy was deemed equivalent or superior in two thirds of dose-volume point comparisons. In cases of inferiority, differences were either clinically insignificant and/or reflected deliberate tradeoffs to optimize the HT plan. Overall imaging and treatment time (median) was 27 min (range, 16-91 min). According to a patient questionnaire, 78% of patients were satisfied to very satisfied with the treatment process. Conclusions: Helical tomotherapy demonstrated clear advantages over conventional 3D-CRT in this diverse patient group. The prospective trials were helpful in deploying this technology in a busy clinical setting

    Pigeons discriminated between two pairs of durations: a short set (2.5 and 5 sec) and a long set (5 and 10 sec). The pairs were intermixed within sessions and identified by the colors on the signal and choice keys. Once the task was learned, the pigeons experienced the following three conditions seriatim: (1) The signal key was made ambiguous about the test change, but the choice keys were informative (retrospective); (2) the signal key identified the test range, but the choice keys did not (prospective); (3) probe trials were introduced in which the color of the center key signaled one test range, but the color of the choice keys signaled the other test range (inconsistent). Accuracy of choice decreased in the retrospective condition and, returned to baseline levels, was higher under the prospective condition than under the retrospective condition. In a final condition, referred to as conflict trials, the center-key color signified one test range and the choice-key colors the other range. The results from these conflict-inconsistent tests indicate that choice behavior was largely controlled by the signal-key color and not by the choice-key color. We relate these findings to different approaches to timing in animals.

    The requirements for sampling density in uranium hydrogeochemical prospecting are discussed in this paper. The scales for regional hydrogeochemical survey, prospetcing survey and detailed prospecting survey are 1 : 200,000 - 1 : 100,000, 1 : 50,000 - 1 : 25,000 and 1 : 10,000 - 1 : 5,000 respectively. On the basis of explanation to the geological meaning of hydrogeochemical field defined in different stage, the principle, effect and technical requirements of small-medium scale hydrogeochemical prospecting are studied. The reason and advantage of the dispersion train prospecting using in the wet and rainy regions have been suggested. The key to the dispersion train prospecting is the sensitivity and precision of analytic methods. The general indications and salinity (conductivity) should be paid attention to in hydrogeochemical prospecting

  11. Loads and loads and loads: The influence of prospective load, retrospective load, and ongoing task load in prospective memory

    Directory of Open Access Journals (Sweden)

    Beat eMeier

    2015-06-01

    Full Text Available In prospective memory tasks different kinds of load can occur. Adding a prospective memory task can impose a load on ongoing task performance. Adding ongoing task load can affect prospective memory performance. The existence of multiple target events increases prospective load and adding complexity to the to-be-remembered action increases retrospective load. In two experiments, we systematically examined the effects of these different types of load on prospective memory performance. Results showed an effect of prospective load on costs in the ongoing task for categorical targets (Experiment 2, but not for specific targets (Experiment 1. Retrospective load and ongoing task load both affected remembering the retrospective component of the prospective memory task. We suggest that prospective load can enhance costs in the ongoing task due to additional monitoring requirements. Retrospective load and ongoing task load seem to impact the division of resources between the ongoing task and retrieval of the retrospective component, which may affect disengagement from the ongoing task. In general, the results demonstrate that the different types of load affect prospective memory differentially.

    The characteristic properties of the iodine laser (gaseous laser substance, photolytic pump mechanism, variable stimulated emission cross-section) made it possible in a relatively short time to generate ns pulses in the kJ range. The Asterix II and III iodine laser systems at IPP are working successfully, and the question arises what prospects are afforded for further iodine laser development. What are the problems that have to be clarified in order to build 10 or 100 kJ systems for laser fusion experiments. According to our experience these can be classified as follows: 1) Short pulse generation and contrast ratio, 2) pulse shaping in a high-gain laser and amplification in the coherent time range, 3) non-linear properties at high intensities, 4) scalable pumping schemes and chemical processes.

    Ng, Johnny S.T.; SLAC

    2006-01-01

    Ultra high energy cosmic rays (UHECR) have been observed but their sources and production mechanisms are yet to be understood. We envision a laboratory astrophysics program that will contribute to the understanding of cosmic accelerators with efforts to: (1) test and calibrate UHECR observational techniques, and (2) elucidate the underlying physics of cosmic acceleration through laboratory experiments and computer simulations. Innovative experiments belonging to the first category have already been done at the SLAC FFTB. Results on air fluorescence yields from the FLASH experiment are reviewed. Proposed future accelerator facilities can provided unprecedented high-energy-densities in a regime relevant to cosmic acceleration studies and accessible in a terrestrial environment for the first time. We review recent simulation studies of nonlinear plasma dynamics that could give rise to cosmic acceleration, and discuss prospects for experimental investigation of the underlying mechanisms

  15. Development and Prospect of Nanoarchitectured Solar Cells

    Directory of Open Access Journals (Sweden)

    Bo Zhang

    2015-01-01

    Full Text Available This paper gives an overview of the development and prospect of nanotechnologies utilized in the solar cell applications. Even though it is not clearly pointed out, nanostructures indeed have been used in the fabrication of conventional solar cells for a long time. However, in those circumstances, only very limited benefits of nanostructures have been used to improve cell performance. During the last decade, the development of the photovoltaic device theory and nanofabrication technology enables studies of more complex nanostructured solar cells with higher conversion efficiency and lower production cost. The fundamental principles and important features of these advanced solar cell designs are systematically reviewed and summarized in this paper, with a focus on the function and role of nanostructures and the key factors affecting device performance. Among various nanostructures, special attention is given to those relying on quantum effect.

    2018-06-05

    We conducted a study to examine the impact of motivation and length of delay on performance on prospective memory (PM) tasks in 2-year of children. A total of 158 children aged exactly 24 months were asked to perform a naturalistic PM task. Length of delay (10 min; 35 min) and motivation (high; very high) were between-subjects factors. Two thirds of children had to be excluded from the analysis because of poor retrospective memory for the PM task instructions which were no longer remembered at the end of the session. For the children who did remember the instructions, both motivation and delay had significant effects on PM. Also, their PM performance was reliably above zero, even after the long delay. The findings indicate that when children as young as 24 months are able to remember the PM task instructions they can reliably succeed in PM tasks that are intrinsically motivating for them.

    2012-01-01

    The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration.   In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon’s prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources.

  18. Prospects for neutron-antineutron transition search

    International Nuclear Information System (INIS)

    Kamyshkov, Y.; Tennessee Univ., Knoxville, TN

    1996-01-01

    Presently-available sources of free neutrons can allow an improvement in the discovery potential of a neutron-antineutron transition search by four orders of magnitude as compared to that of the most recent reactor-based search experiment performed at ILL in Grenoble. This would be equivalent to a characteristic neutron-antineutron transition time limit of >10 10 seconds. With future dedicated neutron-source Facilities, with further progress in cold-neutron- moderator techniques, and with a vertical experiment layout, the discovery potential could ultimately be pushed by another factor of ∼100 corresponding to a characteristic transition time limit of ∼10 11 seconds. Prospects for, and relative merits of, a neutron-antineutron oscillation search in intranuclear transitions are also discussed

  19. Earth Rotation Dynamics: Review and Prospects

    Science.gov (United States)

    Chao, Benjamin F.

    2004-01-01

    Modem space geodetic measurement of Earth rotation variations, particularly by means of the VLBI technique, has over the years allowed studies of Earth rotation dynamics to advance in ever-increasing precision, accuracy, and temporal resolution. A review will be presented on our understanding of the geophysical and climatic causes, or "excitations", for length-of-day change, polar motion, and nutations. These excitations sources come from mass transports that constantly take place in the Earth system comprised of the atmosphere, hydrosphere, cryosphere, lithosphere, mantle, and the cores. In this sense, together with other space geodetic measurements of time-variable gravity and geocenter motion, Earth rotation variations become a remote-sensing tool for the integral of all mass transports, providing valuable information about the latter on a wide range of spatial and temporal scales. Future prospects with respect to geophysical studies with even higher accuracy and resolution will be discussed.

    2014-01-01

    Compared to Multi Wires Proportional Chambers (MWPC), Micro-Pattern Gas Detectors (MPGD) used in HEP to detect MIPs offer better spatial resolution, counting rate capability, and radiation hardness; their fabrication is also more reproducible. Provided similar advantages are applicable to detect neutrons, MPGDs might contribute significantly to the development of neutron scientific instrumentation. In order to evaluate the prospects of neutron MPGDs, it is worth knowing the applications which would benefit from a gain in performance, and if they offer a competitive alternative to conventional 3He detectors. These questions have been at the focus of the workshop "Neutron Detection with Micro-Pattern Gaseous Detectors" organized by RD51 in collaboration with HEPTech, which took place at CERN on October 14-15, 2013. The goal of this workshop was to help disseminating MPGD technologies beyond High Energy Physics, and to give the possibility to academic institutions, potential users and industry to meet together. ...

    Ratynskiy, V M; Reznik, A M; Zekel, L A; Zharov, Yu N

    1979-01-01

    The authors conducted research in order to establish the physical-chemical mechanisms governing the behavior of rare and dispersed elements within the thermal treatment processes used to treat coal and enrichment waste. New means are proposed for obtaining concentrations of gallium. These methods are under consideration primarily for the isolation of gallium as a by-product during the production of aggloporite from coal waste. The authors examine in detail the results of research dealing with the transfer of gallium compounds in a solution, the extraction of gallium from solutions, the separation of impurities from gallium, and the isolation of gallium from extract. Utilizing research results, the authors determine the expenditure coefficient and costs for additives used to extract gallium from waste by-products. The realization of this gallium extraction process from those products having the best prospects for gallium content resulted in economic savings.

    2017-10-25

    Preserving gastric function and improving quality of life (QOL) is the tendency of surgery for early gastric cancer. Function preserving gastrectomy (FPG) is applied to modify the extent of surgery and to achieve better quality of life at the premise of radical resection. Pylorus-preserving gastrectomy is the most favorable approach of FPG with oncological safety, which can improve nutritional status and QOL via preserving pylorus and vagal nerve. Proximal gastrectomy is widely accepted as FPG for early upper 1/3 gastric cancer. However, the most optimal way of anastomosis is not yet solved. Sentinel node navigation is currently the most accurate approach for intraoperative diagnosis of lymph node metastasis, which stimulates the development of many kinds of FPG procedures for individual treatment. Nevertheless, more efforts should be made to reduce false negative rate of sentinel node biopsy. Herein we discuss the valuation and prospect of FPG.

    2013-01-01

    The Earth has limited material and energy resources while these resources in space are virtually unlimited. Further development of humanity will require going beyond our planet and exploring of extraterrestrial resources and sources of unlimited power.   Thus far, all missions to asteroids have been motivated by scientific exploration. However, given recent advancements in various space technologies, mining asteroids for resources is becoming ever more feasible. A significant portion of asteroids value is derived from their location; the required resources do not need to be lifted at a great expense from the surface of the Earth.   Resources derived from Asteroid not only can be brought back to Earth but could also be used to sustain human exploration of space and permanent settlements in space.   This book investigates asteroids' prospective energy and material resources. It is a collection of topics related to asteroid exploration, and utilization. It presents past and future technologies and solutions t...

    1994-01-01

    Dry storage of spent nuclear fuels is one method of dealing with radioactive waste. This article reports from a one day seminar on future prospects for dry fuel storage held in November 1993. Dry storage in an inert gas or air environment in vaults or casks, is an alternative to wet storage in water-filled ponds. Both wet and dry storage form part of the Interim Storage option for radioactive waste materials, and form alternatives to reprocessing or direct disposal in a deep repository. It has become clear that a large market for dry fuel storage will exist in the future. It will therefore be necessary to ensure that the various technical, safety, commercial, legislative and political constraints associated with it can be met effectively. (UK)

    Development of renewable energies in Australia is still in its infancy and will require active support by government, utilities and financing institutions to ensure a steady growth. Much has been done to increase the utilisation of renewable energies in the energy supply, but much still remains to be done, especially in the areas of promotion, demonstration, training and technology transfer. This process will lead to meeting the energy needs of the population in rural areas and to contributing to a suitable development of the region during the next century. Australia is endowed with a wealth of renewable energy resources that hold great promise for addressing a host of important environmental, employment and socioeconomic issues. Australia has a set of climate, geographic and other factors that provide favourable conditions for many specific renewable energy applications. The objectives of this paper is to look at the current situation of renewable energies in Australia, opportunities, constraints, current projects, available potential and future prospects. (Author)

    2013-11-04

    Laser ignition (LI) has been shown to offer many potential benefits compared to spark ignition (SI) for improving the performance of internal combustion (IC) engines. This paper outlines progress made in recent research on laser ignited IC engines, discusses the potential advantages and control opportunities and considers the challenges faced and prospects for its future implementation. An experimental research effort has been underway at the University of Liverpool (UoL) to extend the stratified speed/load operating region of the gasoline direct injection (GDI) engine through LI research, for which an overview of some of the approaches, testing and results to date are presented. These indicate how LI can be used to improve control of the engine for: leaner operation, reductions in emissions, lower idle speed and improved combustion stability.

    Given a sufficiently large universe, numerous civilizations almost surely exist. Some of these civilizations will be short-lived and die out relatively early in their development, i.e., before having the chance to spread to other planets. Others will be long-lived, potentially colonizing their galaxy and becoming enormous in size. What fraction of civilizations in the universe are long-lived? The ''universal doomsday'' argument states that long-lived civilizations must be rare because if they were not, we should find ourselves living in one. Furthermore, because long-lived civilizations are rare, our civilization's prospects for long-term survival are poor. Here, we develop the formalism required for universal doomsday calculations and show that while the argument has some force, our future is not as gloomy as the traditional doomsday argument would suggest, at least when the number of early existential threats is small.

    2014-01-01

    Full Text Available The article analyses the modern state of the banking sector of Ukraine, its sources and prospects. It identifies that the main obstacle for stable development is dissociation of banking segments, absence of functional unity and orientation at formation of optimal conditions for satisfaction of financial requirements of the domestic economy. In order to create the efficient banking system it is necessary to introduce new banking supervision standards oriented at specialisation of the banking activity. The banking market should be segmented and both major banks that form the nucleus of the segment and minor ones operating in their niches should co-operate within each segment. Universal banks that have a developed branch network should unite specialised segments. Moreover, it is necessary to introduce changes into the mechanism of application of some instruments of money and loan regulation with respect to specialised banks and introduce some restrictions upon spheres of activity of the foreign capital.

  18. Prospects for Precision Neutrino Cross Section Measurements

    Energy Technology Data Exchange (ETDEWEB)

    Harris, Deborah A. [Fermilab

    2016-01-28

    The need for precision cross section measurements is more urgent now than ever before, given the central role neutrino oscillation measurements play in the field of particle physics. The definition of precision is something worth considering, however. In order to build the best model for an oscillation experiment, cross section measurements should span a broad range of energies, neutrino interaction channels, and target nuclei. Precision might better be defined not in the final uncertainty associated with any one measurement but rather with the breadth of measurements that are available to constrain models. Current experience shows that models are better constrained by 10 measurements across different processes and energies with 10% uncertainties than by one measurement of one process on one nucleus with a 1% uncertainty. This article describes the current status of and future prospects for the field of precision cross section measurements considering the metric of how many processes, energies, and nuclei have been studied.

    2013-05-01

    Full Text Available Cultured meat, or in vitro meat, is one of the ideas that are being proposed to help solve the problems associated with the ever-growing global meat consumption. The prospect may bring benefit for the environment, climate, and animal ethics, but has also generated doubts and criticism. A discussion of the possible environmental benefit and of animal ethics issues in relation to cultured meat production will be given. A perceived 'unnaturalness' of cultured meat may be one of the strongest barriers for public acceptance. This will be discussed and rejected. As to our relations with nature and animals, it is plausible that cultured meat will lead to improvement rather than to deterioration. The issue of public acceptance and some of the problems of introducing this new product on the market will also be discussed.http://dx.doi.org/10.5324/eip.v7i1.1788

  1. Higgs searches and prospects at CDF

    International Nuclear Information System (INIS)

    Pavel A Murat

    2003-01-01

    The Standard model of electroweak interactions (SM) has been extremely successful in describing interactions of elementary particles over the last decades. The Higgs scalar boson is one of the key elements of the SM: Higgs interactions with the other particles generate the particle masses and allow to keep the theory renormalizable at electroweak scale. All the particles predicted by the SM but the Higgs boson have already been observed experimentally and therefore search for the Higgs is one of the most important scientific goals for high energy physics. The current lower limit on the SM Higgs mass M H > 114.4 GeV at 95% CL has been established by LEP experiments. In this paper we review CDF Run I results on Higgs searches including the Higgs bosons predicted by the minimal supersymmetric extention of the Standard Model (MSSM) and discuss the Run II prospects

    The existence of the cosmic neutrino background (CνB) is a fundamental prediction of the standard Big Bang cosmology. Although current cosmological probes provide indirect observational evidence, the direct detection of the CνB in a laboratory experiment is a great challenge to the present experimental techniques. We discuss the future prospects for the direct detection of the CνB, with the emphasis on the method of captures on beta-decaying nuclei and the PTOLEMY project. Other possibilities using the electron-capture (EC) decaying nuclei, the annihilation of extremely high-energy cosmic neutrinos (EHECνs) at the Z-resonance, and the atomic de-excitation method are also discussed in this review (talk given at the International Conference on Massive Neutrinos, Singapore, 9-13 February 2015).

  3. Innovation and design approaches within prospective ergonomics.

    Liem, André; Brangier, Eric

    2012-01-01

    In this conceptual article the topic of "Prospective Ergonomics" will be discussed within the context of innovation, design thinking and design processes & methods. Design thinking is essentially a human-centred innovation process that emphasises observation, collaboration, interpretation, visualisation of ideas, rapid concept prototyping and concurrent business analysis, which ultimately influences innovation and business strategy. The objective of this project is to develop a roadmap for innovation, involving consumers, designers and business people in an integrative process, which can be applied to product, service and business design. A theoretical structure comprising of Innovation perspectives (1), Worldviews supported by rationalist-historicist and empirical-idealistic dimensions (2) and Models of "design" reasoning (3) precedes the development and classification of existing methods as well as the introduction of new ones.

  4. Heavy ion fusion: Prospects and status

    Herrmannsfeldt, W.B.

    1995-01-01

    Key events in the Heavy Ion Fusion (HIF) field are usually marked by the dates for the International Symposium series which began in 1976 at the Claremont Hotel, and most recently in the eleventh meeting in the series at the Princeton Plasma Physics Laboratory in September 1995. The main purpose of this talk will be to review the status of HIF as it was presented at Princeton, and also to try to deduce something about the prospects for HIF in particular, and fusion in general, from the world and US political scene. The status of the field is largely, though not entirely, expressed through presentations from the two leading HIF efforts: (1) The US program is primarily concerned with applying induction linac technology for HIF drivers; (2) The European program, centered at GSI, Darmstadt, but including several other laboratories, is primarily directed towards the rf linac approach using storage rings for energy compression

  5. Magnetic mirror fusion: status and prospects

    Post, R.F.

    1980-01-01

    Two improved mirror systems, the tandem mirror (TM) and the field-reversed mirror (FRM) are being intensively studied. The twin practical aims of these studies: to improve the economic prospects for mirror fusion power plants and to reduce the size and/or complexity of such plants relative to earlier approaches to magnetic fusion. While at the present time the program emphasis is still strongly oriented toward answering scientific questions, the emphasis is shifting as the data accumulates and as larger facilities - ones with a heavy technological and engineering orientation - are being prepared. The experimental and theoretical progress that led to the new look in mirror fusion research is briefly reviewed, the new TM and the FRM ideas are outlined, and the projected future course of mirror fusion research is discussed

  6. Nuclear power: Status report and future prospects

    International Nuclear Information System (INIS)

    Budnitz, Robert J.

    2016-01-01

    This article reviews the current status and future prospects of commercial nuclear electric power, with emphasis on issues of safety, physical security, proliferation, and economics. Discussions of these issues are presented separately for the current operating fleet, for new reactor designs similar in size to the current fleet, and for prospective new reactors of substantially smaller size. This article also discusses the issue of expansion of commercial nuclear power into new countries. The article concludes with recommendations, related both to technical issues and policy considerations. The major implications for policy are that although the level of safety and security achieved in today's operating reactor fleet worldwide is considered broadly acceptable, some advanced designs now under development potentially offer demonstrably safer performance, and may offer improved financial performance also. Management and safety culture are vital attributes for achieving adequate safety and security, as are a strong political culture that includes an absence of corruption, an independent regulatory authority, and a separation of nuclear operation from day-to-day politics. In some countries that are now considering a nuclear-power program for the first time, careful attention to these attributes will be essential for success. - Highlights: •Current status of nuclear reactor safety and security is judged to be adequate. •Strong management and safety culture are vital to achieve adequate nuclear safety. •Advanced reactor designs offer important safety advantages. •Maintaining and strengthening international nuclear institutions is important. •Achieving nuclear safety in “newcomer” countries requires a strong political culture.

    Protactinium-231 ( 231 Pa) occurs in nature as a member of the decay chain of naturally occuring 235 U of the 4n+ 3 radioactive series. The expected protactinium concentration in the Jaduguda ore body (with uranium concentration of 0.03-0.06 %) is around 0.2 parts per billion (ppb) and that in monazite ore (uranium concentration 0.3%) is 0.9 ppb. The process at uranium ore processing plant at Jaduguda was studied. 231 Pa content in samples from the process streams of the plant was determined. The gamma ray spectrometry method was chosen and standardised in our laboratory to detect and measure 231 Pa in parts per billion levels in these samples. A concentrated source of protactinium could not be found among the assessed streams of Jaduguda uranium plant. The Monazite processing plant at IRE, Aluva was then studied. From the known chemistry of protactinium, the possible distribution of the 231 Pa was guessed at. Accordingly, the process streams of IRE process plant were selected to prospect for 231 Pa and determine the fractionation of protactinium. For analysis of 231 Pa, the thorium bearing samples were chemically treated to remove the thorium daughter products, which interfere in gamma spectrometry. This report describes the planning for prospecting, sample selection, the standardisation of the analysis procedure for determination of 231 Pa content, and the analysis results. The 231 Pa content in various streams of Indian Rare Earths plant was found in the range 0.2 -6.5 ppb. Some of the streams did not carry any protactinium. The fractionation of 231 Pa in the various streams of the plant and the selection of source for recovery of protactinium are discussed in detail. (author)

  8. Shale gas exploitation: Status, problems and prospect

    Directory of Open Access Journals (Sweden)

    Shiqian Wang

    2018-02-01

    Full Text Available Over the past five years, great progress has been made in shale gas exploitation, which has become the most driving force for global gas output growth. Hydrocarbon extraction from shale helps drive the USA on the road to energy independence. Besides, shale oil & gas production has been kept in a sustained growth by continuous improvement in drilling efficiency and well productivity in the case of tumbling oil prices and rig counts. Shale gas reserves and production have been in a rapid growth in China owing to the Lower Paleozoic Wufeng and Longmaxi shale gas exploitation in the Sichuan Basin, which has become an important sector for the future increment of gas reserves and output in China. However, substantial progress has been made neither in non-marine shale gas exploitation as previously expected nor in the broad complicated tectonic areas in South China for which a considerable investment was made. Analysis of the basic situation and issues in domestic shale gas development shows that shale gas exploitation prospects are constrained by many problems in terms of resources endowment, horizontal well fracturing technology, etc. especially in non-marine shale deposits and complicated tectonic areas in South China where hot shales are widely distributed but geological structures are found severely deformed and over matured. Discussion on the prospects shows that the sustained and steady growth in shale gas reserves and production capacity in the coming years lies in the discovery and supersession of new shale plays in addition to Wufeng and Longmaxi shale plays, and that a technological breakthrough in ultra-high-pressure and ultra-deep (over 3500 m buried in the Sichuan Basin marine shale gas exploitation is the key and hope.

  9. MARICULTURE DEVELOPMENT IN INDONESIA: Prospects and Constraints

    Directory of Open Access Journals (Sweden)

    Michael A. Rimmer

    2010-12-01

    Full Text Available Mariculture is an important component of Indonesian fisheries and aquaculture production, directly contributing an estimated US$ 320 million in 2008. Because most mariculture production is focussed on producing for export markets, mariculture production is an important source of foreign earnings for the Indonesian economy. This paper reviews the current status and prospects for continuing development of mariculture in Indonesia. Currently the major mariculture commodity in Indonesia is seaweed for carrageenan production. Seaweed production accounts for 98% of total Indonesian mariculture production and 84% of value. The other major commodity groups are marine finfish and pearl oysters. Commodities being developed for mariculture in Indonesia include abalone and spiny lobsters. Prospects for continued development of mariculture in Indonesia appear positive. Indonesia has several advantages for mariculture development, including many potential mariculture sites, a stable tropical climate, and does not suffer from cyclonic storms. The Government of Indonesia is planning to increase aquaculture production substantially over the next four years, including mariculture production. Globally, demand for seafood products is expanding due to increasing population and increased per capita consumption of fish products. Constraints to the continued development of mariculture in Indonesia include: limited seed supply, particularly of species which cannot be economically produced in hatcheries, such as spiny lobsters; need to develop more efficient production systems for some marine finfish; the need to improve environmental sustainability by improving feeds and reducing environmental impacts; and market issues relating to environmental sustainability.

  11. Prospective memory: effects of divided attention on spontaneous retrieval.

    Harrison, Tyler L; Mullet, Hillary G; Whiffen, Katie N; Ousterhout, Hunter; Einstein, Gilles O

    2014-02-01

    We examined the effects of divided attention on the spontaneous retrieval of a prospective memory intention. Participants performed an ongoing lexical decision task with an embedded prospective memory demand, and also performed a divided-attention task during some segments of lexical decision trials. In all experiments, monitoring was highly discouraged, and we observed no evidence that participants engaged monitoring processes. In Experiment 1, performing a moderately demanding divided-attention task (a digit detection task) did not affect prospective memory performance. In Experiment 2, performing a more challenging divided-attention task (random number generation) impaired prospective memory. Experiment 3 showed that this impairment was eliminated when the prospective memory cue was perceptually salient. Taken together, the results indicate that spontaneous retrieval is not automatic and that challenging divided-attention tasks interfere with spontaneous retrieval and not with the execution of a retrieved intention.

    Directory of Open Access Journals (Sweden)

    Dino Gavinelli

    2012-02-01

    Full Text Available The case of Sesto San Giovanni (SSG, a town marked by a previously intense industrial development then into an equally fast decline of production, may show effectively the impact of the urban regeneration, with the implied redesign of landscape and land policies. The whole process of gradual dismissal of manufacturing, the dynamics of industrial restructuring and the urban processes of recovery, reuse, reclamation and enhancement are triggering a wide debate among geographers and in other fields of research. Being probably the most complex product of human civilization, the city is obviously the most sophisticated and clarifying subject for territorial, social, economical, anthropological, linguistic and cultural studies. As a territorial framework, it is difficult to conceive globally: its boundaries are unstable, and its shapes tend to change very quickly. SSG entered the twenty-first century as a "visible city", a place where its dwellers, old and new, may find at the same time the marks of history and the signs of urban regeneration. However, SSG is also an “invisible city”, soaked with a symbolic heritage that requires protection, preservation and enhancement. Precisely for this reason the municipality decided to apply for UNESCO’s support, in order to protect its industrial heritage. Symbols, signs and values, at the same time, may prove a great resource to be moulded and exploited in terms of  major events such as the International Expo scheduled for 2015, which could prove a great opportunity for the city.

    2017-03-01

    Full Text Available In this paper, the authors present their field experiences as volunteers of the association “Psicologi per i Popoli − Trentino” in the aftermath of the 24th August 2016 earthquake, which struck especially Amatrice and the neighbouring municipalities. From those experiences, the whish emerged to share an “operational model” concerning the psychologist’s role when collaborating with the technical team responsible for habitability assessment (engineers, architects, surveyors and fire fighters, and helping people to collect their personal belongings from their houses. Hence the need arises to promote an approach towards the integration of the various professional roles which preserves their specificity. A reflective approach would represent a collaborative way of working, a different intervention perspective, and would allow a constructive self-positioning in the situation and context in which everyone operates. Through some reports from the field experience, both with people and technical teams, this paper will underline the importance of an integrated work among professionals involved in the emergency situations with different roles. Some reflections for the future will be provided, particularly about the prevention of burn-out and the training of the technical teams involved in the maxi-emergency context. Thanks to this “operational model”, the inclusion of psychologists in multidisciplinary teams will help in keeping the focus on the fundamental elements of well-being for all the people involved in the different emergency phases.

  16. L'impatto delle nuove tecnologie sulle forme di lavoro: una prospettiva europea (Technical Change and Employment: A European Perspective

    Directory of Open Access Journals (Sweden)

    Marcella Corsi

    2001-03-01

    Full Text Available This paper focuses on the role of knowledge within the process of growth and job creation in the European Union. Many features of the so-called knowledge-based economy are connected with the increasing use of information and communication technologies (ICT, that radically changes the conditions for the production and distribution of knowledge as well as its coupling to the production system. Technological change not only stimulates investment in physical capital but also brings to knowledge accumulation: human skills are required to implement, maintain, adapt and use technologies embodied in physical capital. Indeed, as new technologies become more widespread, certain skills may be less in demand--because many tasks once carried out manually are now performed by automated equipment--while the demand for workers able to maintain, program, and develop these sophisticated technologies rise. There is therefore concern that technological change may cause unemployment as the result of a mismatch between the demand for labour and the various skills of workers; in this way it may also increase the polarisation of society by widening the gap in income and employment opportunities between those whose skills have been displaced by new technology and those who create and use it.

    Directory of Open Access Journals (Sweden)

    Fulvia D’Aloisio

    2016-05-01

    Full Text Available The paper focuses on the issue of conflict in contemporary metal-mechanic work and inside the traditional site of blucollars conflict, the factory. Based on an ethnographic research on the Fiat-Sata factory of Melfi (founded in 1993, it shows the progressive change of the line of conflict between workers and owners towards a more subjective and existential conflict between time of work and private and familiar life.As some scholars think, the ‘old fashioned’ conflict has not totally disappeared, rather it has changed its sense and value, flowing towards a different configuration. The work reduction, started in Melfi from 2011, when the factory began the decline of its production and resorting to layoffs, has radically changed the work condition and the perception of the future. The sense of the recruitment in FIAT, for the lucky ones who were hired in 1993 and 1994, was such as an existential turnabout, compared to a very contrary past; more recently, the long period of CIG (Cassa Integrazione Guadagni, from the end of 2011 to 2014, and then the new configuration of the multi-national enterprise FCA,  has increased uncertainty, precariousness, fear to loss the job. In this scenario, the conflict should appear as already exceeded, or simply we have to rethink our idea of class conflict, in the current era of manufacturing production, as a new win of the upper classes.

  20. Nuove soluzioni funzionali nelle domus tardoantiche di Ostia attraverso la lettura delle tecniche edilizie e delle tipologie architettoniche

    Directory of Open Access Journals (Sweden)

    Tigne, Raffaella

    2004-12-01

    Full Text Available This research project has as its base my degree thesis. The latter attempted to create new methodology techniques that could be used to identify different phases of building construction. The study focussed in particular on three late antique domus in Ostia: the Domus of the Caupona, the Domus of the Gorgons and the Domus of the Decumanus. Such a study, based on both the stratigraphie records of the standing structures and the analysis of the archives, has allowed me to develop a new methodology, that differs quite markedly from the traditional methods currently used to analyse and date building techniques. The results of this research challenge the common opinion that the late antique domus were built following a single and unitary project. Many different phases have been identified, suggesting that these buildings had a more complex history than previously thought. This evolution must be viewed in the light of social and economic transformations occurring in Late Antiquity i.e.3rd/ 5th century AD. A number of conclusions can be drawn. Firstly, different building projects/phases can be seen in these domus (probably due to the different needs of the customers and, consequently, also a more various range of plans and typologies. Secondly, analysing a wider number of buildings, it has also been possible to suggest new chronologies and functions for some building techniques. Finally the analysis has been extended to the entire city, identifying a new pattern of building location and function within the urban area in Late Antiquity.Este trabajo se basa en mi memoria de lienciatura. El objetivo es la creación de una Nueva técnica metodológica que podría ser usada para identificar diferentes fases constructivas en un edificio. El estudio se centra sobre tres domus tardoantiguas de Ostia: la domus de Caupona, la domus de las Gorgonas y la domus del Decumanus. A partir del análisis del registro estratigráfico se ha desarrollado una nueva metodología que difiere, sustancialmente, de los métodos tradicionales utilizados para la datación de las técnicas constructivas. Los resultados de esta investigación cambian la opinión general que las domus tardoantiguas son el fruto de un único proyecto. Se han identificado varias fases que sugieren que estos edificios tienen una historia más compleja de la que se pensaba, debido a los cambios sociales y económicos ocurridos en la antigüedad tardía. Las conclusiones de la investigación demuestran cómo a las distintas fases y proyectos de las domus se relacionan una*mayor variedad de plantas y de tipología. Al mismo tiempo y analizando un mayor número de edificios, es posible sugerir la presencia de nuevas tipologías para algunas técnicas constructivas. El mismo análisis ha sido extendido a la ciudad entera, identificando nuevos modelos de construcción, localización y función dentro del área urbana en época tardoantigua.

    Introduzione – Nei pazienti con epatopatia cronica, l'ipertensione portale rappresenta la causa delle principali complicanze (sanguinamento da varici, ascite, encefalopatia epatica) che, insieme all’epatocarcinoma, costituiscono la causa più importante di ospedalizzazione e mortalità. Le metodiche gold-standard per la valutazione dell’ipertensione portale sono la misurazione del gradiente di pressione venosa epatica (HVPG) mediante cateterismo delle vene sovraepatiche e l’esofagogastroduodeno...

    Full Text Available I bambini e i ragazzi nel nuovo millennio sono forse più avvezzi alla visione di un film o di una trasmissione televisiva che non alla lettura di un libro. Quello che è certo, è che sono sottoposti a un bombardamento mediatico senza precedenti grazie a canali televisivi specializzati nella produzione di programmi per l’infanzia e l’adolescenza, alla Rete Internet e ai dispositivi mobili di ultima generazione. E a scuola? Come cambia la didattica? Al laboratorio Mela abbiamo documentato con un video l’avvio della prima esperienza delle Cl@ssi 2.0 in Emilia-Romagna nelle scuole secondarie inferiori. Alla fine dei 3 anni di sperimentazione, durante i quali gli insegnanti hanno utilizzato LIM, computer in classe e Moodle per l’insegnamento a distanza, abbiamo invece cercato di capire, con un questionario, come e quanto vengano utilizzati i video per la didattica. Ne sono seguite alcune riflessioni.

  5. AV e attività di eccellenza. Nuove opportunità localizzative nel sistema Roma-Napoli

    Full Text Available Il contributo propone una lettura delle possibili influenze della realizzazione delle reti AV sulla localizzazione/distribuzione di attività di eccellenza, quali attività direzionali, di management, di servizio alle imprese e alla pubblica amministrazione, con specifico riferimento alla tratta AV Roma-Napoli. A partire da una caratterizzazione delle attività di eccellenza, se ne evidenzia anzitutto la spiccata tendenza alla concentrazione urbana, la dipendenza da efficaci connessioni sia immateriali che materiali e la rilevanza assunta dalla variabile temporale nelle scelte localizzative (Sassen, 2001. Quindi, in riferimento ad alcune esperienze europee, si esaminano i principali effetti, in termini di attrazione/concentrazione di tali attività, connessi alla realizzazione delle reti AV (Sands 1993; Vickerman e Ulied, 2006; Gemeente Amsterdam, 2007. Sulla base di tali considerazioni e tenendo conto delle più recenti definizioni e metodi di misura dell’accessibilità (Axhausen et al. 2006; Spiekermann, Wegener, 2005, lo studio propone un indicatore di “accessibilità” finalizzato ad individuare e graduare, in ragione dei livelli di accessibilità, un sistema di luoghi urbani interconnessi mediante reti su ferro (AV e reti metropolitane e regionali dai quali le attività di eccellenza potranno massimizzare il proprio bacino di utenza. L’individuazione di un sistema di luoghi urbani a diverso grado di accessibilità consente di evidenziare le numerose opportunità per la localizzazione di attività di eccellenza che si dischiudono a seguito della riduzione dei tempi di spostamento consentita dalle reti AV. In tal senso, l’indicatore proposto può costituire un utile supporto alle decisioni sia per l’attore pubblico consentendo di governare e orientare i processi di trasformazione conseguenti alla realizzazione della rete AV, estendendone i benefici dalle aree di stazione a più ampie porzioni urbane sia per l’investitore privato, al fine di identificare le localizzazioni ottimali per disporre di un mercato di riferimento il più possibile esteso. Più specificamente, l’indicatore di accessibilità è stato definito in riferimento alla realizzazione della rete AV che collegherà Roma e Napoli in un tempo di 55 minuti. Pertanto, il sistema di aree per la localizzazione delle attività di eccellenza in ciascuna delle due polarità urbane considerate viene individuato ipotizzando un tempo massimo di percorrenza tra i due sistemi urbani pari a 90 minuti. Tale intervallo temporale si ritiene accettabile per il tipo di spostamenti connessi alle attività in esame: non si tratta, infatti, di spostamenti pendolari quanto, piuttosto, di una mobilità connessa alla fornitura di servizi altamente specializzati. Come ben evidenziato in una recente rassegna sul termine accessibilità, il tempo che si è disposti ad impiegare per raggiungere una data destinazione è, infatti, funzione del tipo di utenza e del tipo di attività o, più in generale, della convenienza per un dato individuo o per una data impresa (Litman, 2007. L’indicatore proposto tiene conto, oltre che del tempo di spostamento calcolato sulla rete su ferro sia nella tratta AV di connessione tra i due centri che nella tratta urbana della qualità del viaggio, considerando il numero e il tipo di scambi che è possibile effettuare sulla rete urbana, nell’arco temporale definito. L’applicazione dell’indicatore al sistema urbano integrato Roma-Napoli ha consentito l’individuazione, nelle due polarità urbane, di aree a diverso grado di “accessibilità” a partire dai due punti focali posti nelle stazioni AV e nell’arco temporale individuato e, conseguentemente, delle aree che, in ragione del solo parametro di accessibilità, risultano le più idonee per la localizzazione delle attività in esame.

    The main purpose of this talk is to review the status of HIF as it was presented at Princeton, and also to try to deduce something about the prospects for HIF in particular, and fusion in general, from the world and US political scene. The status of the field is largely, though not entirely, expressed through presentations from the two leading HIF efforts: (1) the US program, centered at LBNL and LLNL, is primarily concerned with applying induction linac technology for HIF drivers; (2) the European program, centered at GSI, Darmstadt, but including several other laboratories, is primarily directed towards the rf linac approach using storage rings for energy compression. Several developments in the field of HIF should be noted: (1) progress towards construction of the National Ignition Facility (NIF) gives strength to the whole rational for developing a driver for Inertial Fusion Energy; (2) the field of accelerator science has matured far beyond the status that it had in 1976; (3) Heavy Ion Fusion has passed some more reviews, including one by the Fusion Energy Advisory Committee (FEAC), and has received the usual good marks; (5) as the budgets for Magnetic Fusion have fallen, the pressures on the Office of Fusion energy (OFE) have intensified, and a move is underway to shift the HIF program out of the IFE program and back into the ICF program in the Defense Programs (DP) side of the DOE

    A number of studies investigating the relationship between personality and prospective memory (ProM) have appeared during the last decade. However, a review of these studies reveals little consistency in their findings and conclusions. To clarify the relationship between ProM and personality, we conducted two studies: a meta-analysis of prior research investigating the relationships between ProM and personality, and a study with 378 participants examining the relationships between ProM, personality, verbal intelligence, and retrospective memory. Our review of prior research revealed great variability in the measures used to assess ProM, and in the methodological quality of prior research; these two factors may partially explain inconsistent findings in the literature. Overall, the meta-analysis revealed very weak correlations (rs ranging from 0.09 to 0.10) between ProM and three of the Big Five factors: Openness, Conscientiousness, and Agreeableness. Our experimental study showed that ProM performance was related to individual differences such as verbal intelligence as well as to personality factors and that the relationship between ProM and personality factors depends on the ProM subdomain. In combination, the two studies suggest that ProM performance is relatively weakly related to personality factors and more strongly related to individual differences in cognitive factors.

    Full Text Available The aim of the work was a generalization of literature data on the prospects for curcumin usage in biotechnology as a component for biologically active nanocomplexes with anti-inflammatory and antioxidant activity creation. It is emphasized that their effectiveness depends on the solubility in aqueous medium and on the metabolism rate decreasing in the body. Current trend is the development of creation methods of hydrophilic curcumin-based nanostructures to increase the time of its biological action. Its nanostructures with silicium, polylysine, copolymers of lactic and glycolic acids and metal ions are the most promising in this respect. For multicomponent hybrid nanoparticles effective usage the substantiation of their component combined use features is necessary. The practical task is to create and to study the functional properties of such combined nanocomplexes. Curcumin complex with metal ions creation contributes to its water solubility and to increase the efficiency of biological action. These complexes have specific characteristics depending on the nature of metal ion. The creation of curcumin-based biocompatible nanocomposites with amplifiers of its action that are known pharmaceuticals is perspective. Such multifunctional nanocomplexes will facilitate the targeted medicines delivery to the places of pathological processes localization and the reduction of their side effects.

It is a major cause of epilepsy in the tropics and the commonest cause of focal seizures in North Indian children. T. solium teniasis-cysticercosis is considered a parasitic “Neglected Tropical Diseases” endemic throughout Southeast Asia. NCC in children has pleomorphic manifestations depending on the location, number and viability of the cysts, and host response. Even with advancing knowledge of the disease manifestations, many aspects related to diagnosis and treatment, particularly in children, still remain controversial and pose challenges to clinical practice. There is no gold standard test to diagnose NCC and the management recommendations are still emerging. This review provides an overview of diagnosis of NCC in children and its management with special focus on current challenges and future prospects.Keywords: neurocysticercosis, children, epilepsy, ring enhancing lesions, pigs

    Full Text Available When projecting livestock environmental prospects for the 1990's. it is critical to recognize the multidimensional nature of managing livestock species under hot environments. This paper identifies potential critical physiological windows during the life cycle of the animal that are sensitive to heat stress and responsive to environmental modification. Ovarian follicular development appears to be sensitive to heat stress leading to reductions in intensity of oestrus and subsequent fertility. Periods of follicular development that are sensitive to heat stress have not been defined. With current improved systems to alter the microenvironment of animals. the period of embryonic sensitivity to heat stress has shifted so that early embryonic losses are less. Potential recombinant proteins that may enhance embryo survival and correct deficiencies in placental function that are induced by heat stress warrant additional investigation. The postpartum period is a critical period in which a multitude of factors interact to influence animal productivity and its sensitivity to heat stress. Nutritional strategies to improve animal performance with the use of fat-supplementation are discussed. Environmental modification and housing systems need to not only maximize the efficiency of animal production but need to consider the potential impact on the environment relative to water use. soil and water pollution. Animal production and management systems need to consider both animal health and well-being issues. To optimize profit under conditions of greater societal constraints and available management alternatives, computer assisted management systems will become a critical tool.

    Today, EDF is at a half way point in its third major standardized series, the N4 1400 MW series. The main objective agreed upon for this N4 series, was to improve the insertion of man in the control loop. After the TMI accident in 1979, selective improvements had already been introduced in the 900 series ; the 1300 series, which was the underway, was also the object of more significant improvements (for instance a digital control system) ; but it still seemed desirable that all the lessons to be learned from the accident be reflected in the third series : the fully computerized instrumentation and control system developed for the N4 series ?comparable to the one developed for Airbus ?is today the first of its kind in the world. The demand increase for electric energy dramatically stopped in 1993. However, the prospect for the coming years is more optimistic. Electricity consumption is expected to increase slowly by an average 2% per year. In this context, EDF is preparing its energy program for the nest century and takes into account that hydraulic generation capacity will remain stable and that the French thermal units fueled with coal are rather old and will have to be replaced.

    The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration. In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon's prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Moon-related activities and a good starting point for young researchers. (orig.)

    Canada, with its proven, safe and versatile CANDU reactor is well poised for the second half-century of nuclear fission. Canada's nuclear pedigree goes back to the turn-of-the-century work of Ernest Rutherford in Montreal. This year, Canada's nuclear industry celebrates the 50th anniversary of the start-up of its first research reactor at Chalk River. Last year, the pioneering work of Bert ram Blockhouse in Physics was honoured with a Nobel Prize. Future international success for the nuclear industry, such as has been achieved here in Korea, depends on continued cooperative and collaborative team work between the public and private sectors, continued strong research and development backing by the government, and new strategic partnerships. The biggest challenge is financing for the emerging markets. The brightness or dimness of future prospects are relative to the intensity of the lessons learned from history. In Canada we have a fairly long nuclear pedigree, It goes back almost a century to 1898, when Ernest Rutherford set up a world centre at McGill University in Montreal for research into the structure of the atom and into radioactivity

    This paper presents a systematic Structural Equation Modeling (SEM) based approach for Prospective Safety Performance Evaluation (PSPE) on construction sites, with causal relationships and interactions between enablers and the goals of PSPE taken into account. According to a sample of 450 valid questionnaire surveys from 30 Chinese construction enterprises, a SEM model with 26 items included for PSPE in the context of Chinese construction industry is established and then verified through the goodness-of-fit test. Three typical types of construction enterprises, namely the state-owned enterprise, private enterprise and Sino-foreign joint venture, are selected as samples to measure the level of safety performance given the enterprise scale, ownership and business strategy are different. Results provide a full understanding of safety performance practice in the construction industry, and indicate that the level of overall safety performance situation on working sites is rated at least a level of III (Fair) or above. This phenomenon can be explained that the construction industry has gradually matured with the norms, and construction enterprises should improve the level of safety performance as not to be eliminated from the government-led construction industry. The differences existing in the safety performance practice regarding different construction enterprise categories are compared and analyzed according to evaluation results. This research provides insights into cause-effect relationships among safety performance factors and goals, which, in turn, can facilitate the improvement of high safety performance in the construction industry.

    Perovskite solar cells have shown a meteoric rise of power conversion efficiency and a steady pace of improvements in their stability of operation. Such rapid progress has triggered research into approaches that can boost efficiencies beyond the Shockley-Queisser limit stipulated for a single-junction cell under normal solar illumination conditions. The tandem solar cell architecture is one concept here that has recently been successfully implemented. However, the approach of solar concentration has not been sufficiently explored so far for perovskite photovoltaics, despite its frequent use in the area of inorganic semiconductor solar cells. Here, the prospects of hybrid perovskites are assessed for use in concentrator solar cells. Solar cell performance parameters are theoretically predicted as a function of solar concentration levels, based on representative assumptions of charge-carrier recombination and extraction rates in the device. It is demonstrated that perovskite solar cells can fundamentally exhibit appreciably higher energy-conversion efficiencies under solar concentration, where they are able to exceed the Shockley-Queisser limit and exhibit strongly elevated open-circuit voltages. It is therefore concluded that sufficient material and device stability under increased illumination levels will be the only significant challenge to perovskite concentrator solar cell applications.

    Bruxism pathophysiology remains unclear, and its occurrence has been poorly investigated in movement disorders. The aim of this study was to compare the frequency of bruxism in patients with craniocervical dystonia vs. normal controls and to determine its associated clinical features. This is a prospective-control study. A total of 114 dystonic subjects (45 facial dystonia, 69 cervical dystonia) and 182 controls were included. Bruxism was diagnosed using a hetero-questionnaire and a clinical examination performed by trained dentists. Occurrence of bruxism was compared between the different study populations. A binomial logistic regression analysis was used to determine which clinical features influenced bruxism occurrence in each population. The frequency of bruxism was significantly higher in the dystonic group than in normal controls but there was no difference between facial and cervical dystonia. It was also higher in women than in men. Bruxism features were similar between normal controls and dystonic patients except for a higher score of temporomandibular jaw pain in the dystonic group. The higher frequency of bruxism in dystonic patients suggests that bruxism is increased in patients with basal ganglia dysfunction but that its nature does not differ from that seen in bruxers from the normal population.

    As increased recognition for a role of an economical carbon-free nuclear energy, it is expected that possibility for introduction and an expansion of nuclear power plants (NPPs) will be increased around the world,1) with pursuing self-reliant nuclear fuel cycle in certain states to secure assurances of nuclear fuel supply. However, the pursuit of sensitive nuclear technology such as enrichment and reprocessing has led to concerns about nuclear proliferation. The disclosure of nuclear black market has threatened the current global nonproliferation regime.2) To respond to these concerns, efforts have been made to overcome the loophole of the existing nuclear nonproliferation regime. In February 2004, US President Bush proposed that nuclear exporters refuse to transfer sensitive nuclear technology to prevent new states from producing fissile material to close a loophole in the NPT.3) Meanwhile as the amount of spent nuclear fuel (SNF) by once-through fuel cycle increases, the US needs multiple repositories by the end of the century.4) In February 2006, therefore, Bush administration announced the Global Nuclear Energy Partnership (GNEP), which can bring about expansion of nuclear energy including SNF management while decreasing the risk of nuclear proliferation. It is expected that the GNEP will have an effect on national nuclear programs of participating countries as well as nuclear international cooperation. In this regard, this paper discusses the implication of the GNEP and its prospects

    The demand for electricity in developing countries of the world is expected to grow rapidly in the coming decades as these countries undergo the process of industrialization, accompanied by increased urbanization, and seek to improve the living standards of their growing population. The continued heavy reliance of the power sector on fossil fuels will result in an increased dependence of a number of the developing countries on energy imports, with consequentbalance of payment difficulties and implications in terms of reduced energy security, cause severe degradation of the local and regional environment, and will also lead to increasing emissions of greenhouse gases. Increasing the share of hydropower in most of the developing countries is constrained by the limited potential of hydro resources as well as environmental considerations. Other renewable energy technologies such as solar PV and wind power are not expected to play a significant role in the commercial supply of electricity in the foreseeable future in the most part of the developing world. Thus nuclear power as a non-fossil alternative with a proven and mature technology may be called upon to play an increasing role in the future supply of electricity to developing countries. The paper discusses the main factors that are likely to affect, both positively and negatively, the deployment of nuclear power in developing countries and presents the results of the recent IAEA projections on nuclear power capacity growth up to the 2020. The paper also briefly reviews the prospects of nuclear power in Central and Eastern European countries. (author)

  2. Prospects for nuclear power international after Fukushima

    Full-text: The Fukushima accident in March 2011 has imposed a number of significant challenges for the world nuclear industry, in terms of enhancing safety at both existing and prospective reactor sites and in regaining public trust for its operations. Yet despite setbacks in a number of countries (notably Germany in addition to Japan itself) the overall outlook for nuclear power around the world is little changed from before the accident. The front end of the nuclear fuel cycle is fully internationalised and operates as a series of competitive markets, guaranteeing economic supply to the operating reactors around the world. Although new reactor types with potentially different fuelling modes are on the horizon, nothing much is likely to change before 2030. The back end is, however, comparatively less developed and there remain substantial uncertainties how it will develop in the future. Technical solutions exist, but governments have failed to grasp realities in used fuel management and waste disposal. Although many commentators argue that low levels of public acceptance are the prime reason for nuclear power failing to take a more substantial part of the energy mix, the root cause is relatively poor economics (at least in much of the Western world). Plants cost too much to build, essentially taking too long to complete, by comparison with rival generating technologies. Additionally, cheap natural gas has become a barrier in certain markets. The risk profile of nuclear projects therefore makes it difficult to attract financing but there are some possible solutions to these issues. (author)

  3. Prospect of nuclear application in food technology

    Irradiation changes the normal living process of cells and the structure of molecules. It is good for food preservation because it kills off many of the microorganisms in the product and makes the remainder more sensitive to antimicrobial factors prevailing after the radiation treatment. It offers more benefits than conventional preservation in that it increases storage stability and quality of foodstuffs with the minimum use of energy. Good storage quality gives way to wider distribution of food, alleviates the world's food shortage, and improves food supplies. Research proved that irradiation increased the quality of subtropical fruits, spices, fish, and meat. No refrigeration is needed to store meat, poultry and fish preserved by the combination of irradiation and mild heat treatment. Nuclear technology can also be applied to destroy harmful insects, to sterilize food, to inhibit the sprouting of root crops, and to control ripening in stored fruits and vegetables. Based on the above potentials of irradiation, the prospect of nuclear application in food technology is promising.

    In this paper the authors examine the prospects of the main ceramics proposed as breeder materials for fusion reactors, i.e. Li-2O, Li-2ZrO-3, LiAlO-2, Li-4SiO-4. To do so they review terms of reference of contemplated blankets for NET, ITER and DEMO, and the proposed blanket concepts and materials. Issues respective to the use of each breeder material are examined, and from this review it is concluded that ceramics are the most favorable breeder materials whose use can be contemplated as well for a driver blanket for NET or ITER and for a DEMO blanket. Ceramics are then compared between themselves and it is seen that, subject to the confirmation of recent experimental results, lithium zirconate could be used with advantage in any of the present blanket concepts, except in those employing lithium at its natural isotopic abundance, in which case only Li-2O can be used. However in specific cases, or in parts of a blanket, other ceramics may be profitably employed. As a general conclusion suggestions are made to further improve ceramic breeder performances, and it is recommended to intensify also work on problems that have to be solved in order to operate ceramic breeder blankets e.g. tritium extraction and recovery systems and conditions of beryllium use.

    Full Text Available Russian – Turkish relations go deep into the past. From the Cold War and the relations between the Soviet Union and the United States certainly there has not been a more complicated relationship in international relations. Both countries have different strategic positions, a different dominant religion, a different past, but their relationship largely depends on the future of Eurasia. This paper will deal with relations between the two countries since the establishment of the first diplomatic contacts in the 15th century, through the relationship during the time of Peter the Great, and will mention the periods of the First and Second World Wars, as well as the Cold War era. Special attention will be focused on the current relations between the two countries, especially after the conflict in 2015, when Turkey shot down a Russian plane over Syria. Special attention will be focused on energy policy and the potential for building a nuclear power plant in Mersin, and the continuation of Turkish stream. The paper will deal with economics and trade exchange, which have almost disappeared following the 2015 incident, security cooperation and Turkey’s plans to buy the defense system S-400 from Russia, as well as relations between the two countries towards NATO. The paper will end with the projection of the prospects for the economic relations between the two countries.

    Full Text Available The aim of the article is to identify the current trends in the development of social entrepreneurship in Ukraine as a new form of doing business in the context of socio-economic transformations. By analyzing and generalizing scientific works of many scientists, the evolution of the development of social enterprises is considered, the views of researchers on the definition of the concept of “social entrepreneurship” and its key factors are systematized. The modern tendencies, main barriers and opportunities for the development of social entrepreneurship in Ukraine are revealed. As a result of the research, differentiation of social enterprises according to the level of social and business activity is proposed. The experience of formation and development of social entrepreneurship in European countries is studied. It is substantiated that under the current conditions of transition from the resource-oriented paradigm of economic development to the value-oriented one, the motivational component of human labor changes: money loses the role of a key motivational factor; possibility of creating economic values for others by implementing own plans and initiatives comes to the fore. A prospect for further research in this area is studying regulatory and legal aspects of the emergence of social entrepreneurship in Ukraine as a driver of sustainable economic development of the country.

No treatment has been available for the women suffering from an absent or dysfunctional uterus, in terms of carrying a pregnancy. Approximately one in 500 women suffer from absolute uterine infertility, and the option so far to become a mother has been to either adopt or utilize gestational surrogacy. As of today, a total of eleven cases of human uterus transplantations have been reported worldwide, conducted in three different countries. The results of these initial experimental cases far exceed what might be expected of a novel surgical method. Many more uterus transplantations are to be expected in the near future, as other research teams’ preparations are being ready to be put into clinical practice. In this review, we summarize the current worldwide experience of uterus transplantation as a treatment of absolute uterine factor infertility and the future prospects of human uterus transplantation.

  8. International nuclear markets: Problems and prospects

    1984-01-01

    International nuclear trade is now of considerable importance for the energy balances of a number of countries. From the start, it has been regulated by bilateral or multilateral agreements, ones that always included conditions to obtain non-proliferation assurances with verification requirements, now based on IAEA safeguards. Nuclear trade indeed would have been impossible without the non-proliferation regime that has been developed. Recently, non-proliferation objectives and conditions have come to dominate discussions about international nuclear trade through restrictions introduced in the 1970s as a result of developing national policies. The International Nuclear Fuel Cycle Evaluation (INFCE) 1977-1980, and most recently the Committee of Assurances of Supply (CAS) established by the IAEA Board of Governors in 1980, have studied these matters in detail. It sometimes seems, however, that other and possibly more fundamental problems and limitations are given secondary importance. This article discusses some of these factors as regards international trade in nuclear plants and the fuel cycle, and looks at some prospects for the future

    This issue of the ANNALS addresses itself to three aspects of nuclear proliferation: the prospect that new nuclear powers will come on the scene, the problems that their arrival may create, and ways of coping with those problems. In an introductory paper, ''Quo Vadimus,'' Joseph I. Coffey investigates the pros and cons of proliferation, concluding that it is not a question of whether there will be nuclear proliferation, but in what countries. Part I, Where We Are, contains five papers preceded by introductory comments by Joseph I. Coffey. The papers and their authors are: Why States Go--and Don't Go--Nuclear, William Epstein; How States Can ''Go Nuclear,'' Frank C. Barnaby; What Happens If. . .Terrorists, Revolutionaries, and Nuclear Weapons, David Kreiger; Safeguards Against Diversion of Nuclear Material: An Overview, Ryukichi Imai; and Reducing the Incentives to Proliferation, George H. Quester. Part II, And Where We May Go, again includes some introductory remarks by Joseph I. Coffey. The seven succeeding papers are: Nth Powers of the Future, Ashok Kapur; Nuclear Proliferation and World Politics, Lewis A. Dunn; Arms Control in a Nuclear Armed World, Colin Gray; The United Nations, the Superpowers, and Proliferation, Abraham Bargman; Proliferation and the Future: Destruction or Transformation, Frederick C.

  10. Petroleum products : part 1 - overview and prospects

    International Nuclear Information System (INIS)

    1996-01-01

    The petroleum products industry represents the downstream (refining and products marketing) portion of the oil industry. It includes companies that refine crude oil into petroleum products, transport them to distribution storage terminals and sell them directly to major users or wholesale and retail outlets. Issues regarding investment and financing, trade and export strategies, technological innovation and adaptation, human resources, the environment and sustainable development within the sector are discussed, illustrating, among other things, how government and industry can commit to mutually beneficial goals and actions. The petroleum industry is a major source of revenue for Canadian governments which collect about $9 billion annually in federal and provincial taxes on gasoline alone. The industry is capital-intensive and very competitive, with a strong domestic focus. Key points relevant to the sector are examined from the global, North American and Canadian perspectives, highlighting changing conditions and industry responses in both the refining and retailing segments of the sector. Growth prospects in terms of profitability and environmental issues were also analyzed. 11 figs

  11. Endogenous antispermatogenic agents: prospects for male contraception.

    1978-01-01

    A review of endogenous antispermatogenic agents as prospects for male contraception is reported. It is demonstrated that endogenous compounds exert regulatory influences at 4 major levels in the male: 1) between germ cells; 2) between Sertoli and germ cells; 3) between Leydig cells and seminiferous tubules; and 4) between the central nervous system and the testis. Efforts to interrupt spermatogenesis have failed to find application as male contraceptives for various reasons: 1) some investigators ignored the vulnerable control points by utilizing nonspecific agents; 2) others attacked a vulnerable control point but used synthetic drugs that had deleterious side effects; and 3) still others attacked a vulnerable control point with a relatively innocuous drug but used an impractical mode of drug administration. The potential for devising innovative techniques for administering relatively innocuous drugs at dosages sufficient to produce sterility without causing deleterious side effects is demonstrated. The most promising solution for the development of an antispermatogenic male contraceptive is the interference with the adenohypophyseal-gonadal axis via the subcutaneous sustained release of steroid formulations containing either androgen-danazol, androgen-progestin, or androgen-estrogen formulations. Another promising agent would be luteinizing releasing hormone agonist-androgen formulation.

    Radiation Utilization in Japan has been positioned, together with nuclear power generation, as one of the important cornerstones, and research and development and practical usage of it has been proceeded with steadily in the fields of industry, agriculture, medicine, and so on. In the field of medicine, SPECT and PET facilities, radio-immunoassay, radiotherapy has come widely to practical use. In the field of agriculture and fisheries, improvement of breed, sterile insect technique have been implemented, and eradication of melon fly has been achieved. In the field of industry, it is expected that the practical use of neutron radiography technique and research and development of synthesizing high performance, high function materials are progressed. In the environment preservation area, a pilot test using electron beam to treat the exhaust gases out of coal fired power plants, city garbages combustion facilities, city high way tunnels in order to establish de- sulphur/de-nitrogen technique is carried out. As the international contribution in the field of radiation utilization, the cooperation with developing countries and the cooperation among advanced countries are reported. In this paper, a prospect of radioisotopes and radiation utilization is described. (J.P.N.)

    1985-01-01

    The situation in particle physics today is highly analogous to that which existed in chemistry towards the end of the 19th century. During the preceding two centuries, remarkable progress has been achieved in that discipline, progress that culminated in the periodic table of Mendeleyev. This paper summarized not only the realization that the everyday matter is composed of basic building blocks, called elements, but also that these different elements had certain similarities which could be used to properly arrange them in the periodic table. Thus the inert gases (helium, neon, argon, etc.) had very similar chemical properties, namely chemical inertness; the halogens (chlorine, iodine, florine) on the other hand were highly reactive. Other similarities were seen among the rare earth group of elements, alkaline earths, and alkali metals. In this paper the author attempts to summarize briefly the historical background that led us to the present level of understanding, or more specifically to the ''standard model'' of particle physics. He also describes several difficulties with this picture, continues with some possible indications of new physics, and finally end with the discussion of the prospects for the future

    Full Text Available Introduction: The use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results hearing after tympanoplasty and tympanomastoid surgery for chronic otitis media. Today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best.   Materials and Methods: A prospective study of 80 patients who underwent ossiculoplasty was performed in the ear, nose, and throat (ENT department at a tertiary health care facility from 2011 to 2013. Patients with chronic suppurative otitis media with an air-bone gap (ABG of >25 dB with ossicular involvement were included in the study. Total ossicular replacement prosthesis (TORP, partial ossicular replacement prosthesis (PORP, and refashioned incus were used. Success was defined as ABG   Results: The majority patients were of middle age with moderate conductive hearing loss. Incus was the most susceptible ossicle. Overall success rate in this study was 80.0% with an average change of 15.76 dB in ABG.   Conclusion:  With continuing advances in our understanding of middle ear mechanics, the results of ossiculoplasty are improving and results can be very rewarding in experienced hands. Severity of preoperative ear discharge, preoperative mastoid cellularity, presence of disease, and surgical procedure proved to be significant prognostic factors. Autograft incus and PORP fared better when the malleus handle was present while TORP gave better results when the malleus handle was eroded.

    2015-01-01

    Run-I at the LHC has been very successful, including the discovery of a new particle with a mass of about 125 GeV and with properties compatible with those of the Standard Model Higgs boson within uncertainties. Precise measurements of the properties of this boson, and the discovery of new physics beyond the Standard Model, are primary goals of future running at the LHC. The physics prospects based on 300/fb and 3000/fb protonproton collision data to be collected at 14 TeV are presented. The ultimate precision attainable on measurements of the couplings of the 125 GeV particle to elementary fermions and bosons is discussed, as well as perspectives on the searches for partners associated with this new object, predicted by several extensions of the standard theory. Supersymmetry is one of the best motivated and well-studied extensions of the Standard Model. The current searches at the LHC have yielded sensitivity to TeV scale gluinos and 1st and 2nd generation squarks, as well as to 3rd generation squarks and e...

    1977-01-01

    The Geological Survey of Greenland is responsible for most of the uranium and thorium prospecting activity in Greenland, which involves airborne gamma spectrometry and scintillometry, geochemical sampling, geological investigations and ground scintillometry. Since 1971 large areas of east and west Greenland have been investigated by aerial surveys, geochemical sampling and most of the detailed scintillometric work having been restricted to small areas in east Greenland. Anomalous radioactivity in west Greenland is recorded from carbonatite intrusions, and from units in Proterozoic and Archaean gneisses. No mineralization has been found to date. In south Greenland investigations have been centred on the uranium and thorium deposit at Kvanefjeld, which is situated in a corner of the Ilimaussaq alkaline intrusion. The coincidence of favourable conditions during the differentiation and crystallization of the magma led to an extreme enrichment of uranium and thorium in the rocks that were last formed - the lujavrites. The deposit comprises parts of the lujavrites and a secondary enrichment zone in the contact between lujavrite and basaltic cover rocks. Reasonably assured reserves are 5800 t U with a grade of 310 ppm U. In the Caledonides of east Greenland some gneisses in basement cores, a dark siltstone in late Precambrian sediments and the Devonian acid magmatic rocks are characterized by a higher radiation level. A number of small mineral occurrences have been found, the majority of which are associated with the Devonian acid magmatic rocks. (author)

  19. The Prospects of Radical Change Today

    Slavoj Žižek

    2018-05-01

    Full Text Available In this contribution, Slavoj Žižek takes the occasion of Marx’s bicentenary for reflecting on the prospects of radical change today. First, it is shown that under Stalinism, Lenin’s works were quoted out of context in an arbitrary way in order to legitimise arbitrary political measures. Marxism thereby became an ideology that justified brutal subjective interventions. Second, this contribution poses the question of the revolutionary subject and democracy today. It stresses the role of both contingency and strategy in revolutions. In political assemblages taking place on public squares, the inert mass of ordinary people is transubstantiated into a politically engaged united force. The basic political problem today is how to best reconfigure democracy. Third, this contribution analyses the “interesting times” we live in. These are times that feature multiple crises, right-wing populism à la Donald Trump and Marine Le Pen, the lower classes’ opposition to immigration, and the refugee crisis. Questions about human rights and their violation and about radical change need to be asked in this context.

    This presentation provided some basic information, current status and prospects for Iran's petrochemical industry with particular reference to Iran's National Petrochemical Company (NPC), one of the fastest growing chemical producers and exporters in the world. According to Chemical Marketing Associates Inc. (CMAI), NPC will become the second largest commodity chemical producer in the world by 2015, ranking only behind Dow Chemical. Product categories include chemicals and aromatics; fertilizers; polymers; feedstocks and gas. Opportunities for cooperation with North America were also identified. Iran's domestic markets were shown to be well developed downstream petrochemical industries producing a broad range of industrial and consumer goods. Iran's foreign markets include Asia (66 per cent), Middle East (25 per cent), and Europe (9 per cent). This presentation examined Iran's comparative advantage in the further development of its petrochemical/chemical industries. Some details of NPC's organizational structure were also provided, along with production, domestic sales, exports and ongoing expansion and development projects. Remarks on the projected and potential growth in NPC's position in the world markets were included with reference to potential for foreign participation and investment into the petrochemical industry in Iran. tabs., figs

  2. Prospects for ethanol production from whey

    Energy Technology Data Exchange (ETDEWEB)

    Marshall, K R

    1978-05-01

    Whey is a by-product of the manufacture of cheese and casein. Casein whey is not as fully utilized as cheese whey although in the last five years commercial processes have been developed to recover the whey proteins, either in denatured form as lactalbumin or in their soluble form as Solac. The removal of the whey proteins makes little difference to the polluting strength or volume of the whey and a crude lactose solution - serum or permeate - remains to be processed. Many processes have been evaluated for the use of this crude lactose solution; one is microbial transformation to produce products such as methane, ethanol, acetone and butanol and etc. The technologies for these processes are well known and it is the economic evaluation which ultimately determines the feasibility of the process being considered. For the purposes of this paper, the prospects for ethanol production have been evaluated. Unless there is a significant reduction in capital costs, it is concluded that ethanol production from whey is not a viable proposition as an energy source for New Zealand. Industrial ethanol (annual imports; 3.5 x 10/sup 6/ 1 CIF value 32 c/1) and potable ethanol production may be worth contemplating.

    Full Text Available The aim of this article is to examine whether some previous knowledge about business prospects affects companies’ decisions about new employment in Serbia. In order to investigate this assumption a set of firm level data for 2012 is used. Following the theoretical approach that put an employer in a position to make various decisions about employment within the company, the trichotomous logit model is employed for the estimation of outcomes of possible companies’ decisions with respect to a set of independent variables. We find that the level of employment in the year that precedes companies’ decisions and relative changes in the number of employees in two successive years, as well as age and size of the company to some extent, affect companies’ decisions about new employment. The most important finding of our research is that the companies that experienced fluctuations in the number of employees and upgraded their business opportunities in the previous period hesitate to make decisions on the engagement of new workers, whereas those companies that lost some business opportunities rather decide to downsize the total number of employees.

    1997-01-01

    With the current known oil reserves of about 11 billion barrel and annual production of approximately 500 million barrel, the country's oil reserves will be depleted by 2010, and Indonesia would have become net oil importer if no major oil fields be found somewhere in the archipelago. Under such circumstances the development of new sources of liquid fuel becomes a must, and coal liquefaction can be one possible solution for the future energy problem in Indonesia, particularly in the transportation sector due to the availability of coal in huge amount. This paper present the prospect of coal liquefaction in Indonesia and look at the possibility of integrating the process with HTR as a heat supplier. Evaluation of liquidability of several low grade Indonesian coals will also be presented. Coal from South Banko-Tanjung Enim is found to be one of the most suitable coal for liquefaction. Several studies show that an advanced coal liquefaction technology recently developed has the potential to reduce not only the environmental impact but also the production cost. The price of oil produced in the year 2000 is expected to reach US $ 17.5 ∼ 19.2/barrel and this will compete with the current oil price. Not much conclusion can be drawn from the idea of integrating HTR with coal liquefaction plant due to limited information available. (author). 7 figs, 3 tabs

    Boxing remains a subject of controversy and is often classified as dangerous. But the discussion is based mostly on retrospective studies. This survey was conducted as a prospective study. From October 2012 to September 2013, 44 competitive boxers were asked to report their injuries once a month. The questionnaire collected general information (training, competition) and recorded the number of bouts fought, injuries and resulting lost days. A total of 192 injuries were recorded, 133 of which resulted in interruption of training or competition. Each boxer sustained 3 injuries per year on average. The injury rate was 12.8 injuries per 1 000 h of training. Boxers fighting more than 3 bouts per year sustain more injuries (p=0.0075). The injury rate does is not a function of age (age≤19 vs. > 19a, p=0.53). Injuries to the head and the upper limbs occur most frequently. The most common injuries are soft tissue lacerations and contusions. Head injuries with neurological symptoms rarely occur (4.2%). Boxing has a high injury rate that is comparable with other contact sports, but most injuries are minor. Injury frequency is not a function of whether the boxer competes in the junior or adult category. Athletes fighting many bouts per year have a greater risk of injury. © Georg Thieme Verlag KG Stuttgart · New York.

    The aim of this study was to describe the content knowledge especially the concept of fraction of prospective elementary school teacher. The purpose of this study is to describe the content knowledge, especially the concept of fraction of prospective elementary school teacher. The subject of the study was one of prospective elementary school teacher of Pattimura University. This research is qualitative research. Data were collected through the provision of tests to explore the knowledge content of primary school teacher candidates about fractional concepts. Then continued with qualitative data analysis. The results of this study are as follows: that the prospective primary school teacher defines fractions as part of the whole if an object is divided into equal parts, so that the part that has been divided is part of the whole. Furthermore, the prospective elementary school teacher understood the fractions as division shown in two ways, namely the prospective elementary school teacher understood the fraction as a division operation, the primary school teacher candidate interpreted the fraction as a division when an object is divided be part of the same. Meanwhile, the fraction as a ratio is interpreted as the relationship between a pair of numbers. Then, the denominations are interpreted as a ratio between the numerator and the denominator of the same value. The prospective elementary school teacher also understands fractions of value when simplifying fractions. Primary school teacher candidates understand the concept of fractional operations.

    In China it is important to explore coal prospecting by taking advantage of modern remote sensing and geographic information system technologies. Given a theoretical basis for coal prospecting by remote sensing, the methodologies and existing problems are demonstrated systematically by summarizing past practices of coal prospecting with remote sensing. A new theory of coal prospecting with remote sensing is proposed. In uncovered areas, coal resources can be prospected by direct interpretation. In coal bearing strata of developed areas covered by thin Quaternary strata or vegetation, prospecting for coal can be carried out by indirect interpretation of geomorphology and vegetation. For deeply buried underground deposits, coal prospecting can rely on tectonic structures, interpretation and analysis of new tectonic clues and regularity of coal formation and preservation controlled by tectonic structures. By applying newly hyper-spectral, multi-polarization, multi-angle, multi-temporal and multi-resolution remote sensing data and carrying out integrated analysis of geographic attributes, ground attributes, geophysical exploration results, geochemical exploration results, geological drilling results and remote sensing data by GIS tools, coal geology resources and mineralogical regularities can be explored and coal resource information can be acquired with some confidence. 12 refs., 4 figs., 3 tabs.

    In prospective memory tasks different kinds of load can occur. Adding a prospective memory task can impose a load on ongoing task performance. Adding ongoing task load (OTL) can affect prospective memory performance. The existence of multiple target events increases prospective load (PL) and adding complexity to the to-be-remembered action increases retrospective load (RL). In two experiments, we systematically examined the effects of these different types of load on prospective memory performance. Results showed an effect of PL on costs in the ongoing task for categorical targets (Experiment 2), but not for specific targets (Experiment 1). RL and OTL both affected remembering the retrospective component of the prospective memory task. We suggest that PL can enhance costs in the ongoing task due to additional monitoring requirements. RL and OTL seem to impact the division of resources between the ongoing task and retrieval of the retrospective component, which may affect disengagement from the ongoing task. In general, the results demonstrate that the different types of load affect prospective memory differentially. PMID:26082709

    Machine learning methods that have been used in data-driven predictive modeling of mineral prospectivity (e.g., artificial neural networks) invariably require large number of training prospect/locations and are unable to handle missing values in certain evidential data. The Random Forests (RF) algorithm, which is a machine learning method, has recently been applied to data-driven predictive mapping of mineral prospectivity, and so it is instructive to further study its efficacy in this particular field. This case study, carried out using data from Abra (Philippines), examines (a) if RF modeling can be used for data-driven modeling of mineral prospectivity in areas with a few (i.e., individual layers of evidential data. Furthermore, RF modeling can handle missing values in evidential data through an RF-based imputation technique whereas in WofE modeling values are simply represented by zero weights. Therefore, the RF algorithm is potentially more useful than existing methods that are currently used for data-driven predictive mapping of mineral prospectivity. In particular, it is not a purely black-box method like artificial neural networks in the context of data-driven predictive modeling of mineral prospectivity. However, further testing of the method in other areas with a few mineral occurrences is needed to fully investigate its usefulness in data-driven predictive modeling of mineral prospectivity.

    Poland started the works on construction of first nuclear power plant in 1992. The social protest as well as deep political and economical changes in Poland induced the decision of the Polish government to abandon the construction of the nuclear power plant in Zarnowiec. After the period of political and economical transformation, in 1992 Polish economy starts to grow up, also growth of the electric power consumption. Are there prospect for utilization in Poland the nuclear power plant? This work is devoted to analyse such question. The present structure of power and fuel materials in Poland were analysed and the possible direction of changes was shown for the period up to 2020 year. It was stated, that the economical development in Poland should be bound with the growth of the consumption of most effective fuel and energy. These fuel or energy should be imported to Poland. Therefore, the nuclear power should be treated as one of possible ways of the balance of electric power in Poland. Particularly, that it will be expected the special ecological conditions in the energy production in Europe. In the present work, was shown, that the nuclear power was discriminated in the analysis of the development of power and fuel system in Poland. The incorrect values of economical parameters concerning of the nuclear power plant was used in the analysing numerical programs. The investment costs, design time and fuel price for nuclear energy was analysed, and shown, that in the proper conditions, the cost of the electric energy produced in the nuclear power plant is compared with the costs of electric energy produced in the conventional power stations. In this work, the proposals of the basic nuclear and radiological safety standards for the nuclear power plant in Poland are shown. (author). 20 refs, 10 figs, 3 tabs

    Over the last decades, an exponential increase of efforts concerning the treatment of Alzheimer's disease (AD) has been practiced. Phytochemicals preparations have a millenary background to combat various pathological conditions. Various cinnamon species and their biologically active ingredients have renewed the interest towards the treatment of patients with mild-to-moderate AD through the inhibition of tau protein aggregation and prevention of the formation and accumulation of amyloid-β peptides into the neurotoxic oligomeric inclusions, both of which are considered to be the AD trademarks. In this review, we presented comprehensive data on the interactions of a number of cinnamon polyphenols (PPs) with oxidative stress and pro-inflammatory signaling pathways in the brain. In addition, we discussed the potential association between AD and diabetes mellitus (DM), vis-à-vis the effluence of cinnamon PPs. Further, an upcoming prospect of AD epigenetic pathophysiological conditions and cinnamon has been sighted. Data was retrieved from the scientific databases such as PubMed database of the National Library of Medicine, Scopus and Google Scholar without any time limitation. The extract of cinnamon efficiently inhibits tau accumulations, Aβ aggregation and toxicity in vivo and in vitro models. Indeed, cinnamon possesses neuroprotective effects interfering multiple oxidative stress and pro-inflammatory pathways. Besides, cinnamon modulates endothelial functions and attenuates the vascular cell adhesion molecules. Cinnamon PPs may induce AD epigenetic modifications. Cinnamon and in particular, cinnamaldehyde seem to be effective and safe approaches for treatment and prevention of AD onset and/or progression. However, further molecular and translational research studies as well as prolonged clinical trials are required to establish the therapeutic safety and efficacy in different cinnamon spp. Copyright © 2017 Elsevier Ltd.

  19. Prospective Tests on Biological Models of Acupuncture

    Full Text Available The biological effects of acupuncture include the regulation of a variety of neurohumoral factors and growth control factors. In science, models or hypotheses with confirmed predictions are considered more convincing than models solely based on retrospective explanations. Literature review showed that two biological models of acupuncture have been prospectively tested with independently confirmed predictions: The neurophysiology model on the long-term effects of acupuncture emphasizes the trophic and anti-inflammatory effects of acupuncture. Its prediction on the peripheral effect of endorphin in acupuncture has been confirmed. The growth control model encompasses the neurophysiology model and suggests that a macroscopic growth control system originates from a network of organizers in embryogenesis. The activity of the growth control system is important in the formation, maintenance and regulation of all the physiological systems. Several phenomena of acupuncture such as the distribution of auricular acupuncture points, the long-term effects of acupuncture and the effect of multimodal non-specific stimulation at acupuncture points are consistent with the growth control model. The following predictions of the growth control model have been independently confirmed by research results in both acupuncture and conventional biomedical sciences: (i Acupuncture has extensive growth control effects. (ii Singular point and separatrix exist in morphogenesis. (iii Organizers have high electric conductance, high current density and high density of gap junctions. (iv A high density of gap junctions is distributed as separatrices or boundaries at body surface after early embryogenesis. (v Many acupuncture points are located at transition points or boundaries between different body domains or muscles, coinciding with the connective tissue planes. (vi Some morphogens and organizers continue to function after embryogenesis. Current acupuncture research suggests a

  20. Deepwater Gulf of Mexico: high prospects

    The present and future role of the deepwater Gulf of Mexico to meeting natural gas requirements of the United States are reviewed.The steady increase in U.S. demand, outpacing U.S.supply for over 10 years and the increasing reliance by the USA on Canadian exports is demonstrated in conjunction with the '30 Tcf Challenge'. Regarding the Gulf of Mexico specifically, it is estimated that to meet expectations, production there needs to grow to 22 Bcfpd by 2020, especially the deepwater pools which have a potential of 80 to 140 Tcf over the next 50 years. These pools already produce as much oil as the shelf region, but only 25 per cent as much gas. To produce the expected 7 to 12 Bcfpd oil production must reach 4 million barrel of oil per day, which involves cycle time, new technologies and cost challenges. Much of the new technology needed is related to cutting costs and while good progress is being made, it is argued that further gains could occur if international technology were applied in the Gulf. The rate of success in exploration has also improved, with over one billion barrels of deepwater discoveries per year over the last four years. Cycle times have also improved, although the impact of cycle time in the deeper water regions is cause for some concern. The overall assessment is that to get the gas, one has to get the oil first, meaning that deepwater success is more dependent on oil prices than on gas prices. Nevertheless, the need for developing and applying new technologies remains paramount, including the application of existing foreign technologies that have proven successful elsewhere. It is equally important to demonstrate a high level of environmental stewardship, and to continue focusing on cycle time, including access to prospective acreage, a well-trained workforce, and reasonable regulatory and permitting requirements

  1. The prospects for nuclear heating in Hungary

    1989-09-01

    In assessing alternative nuclear heat sources, a joint study was undertaken between Canada and Hungary to determine the feasibility of using the SLOWPOKE Energy System that has recently been developed. The SLOWPOKE Energy System is a benign nuclear heat source designed to supply 10 thermal megawatts in the form of hot water for local heating systems in buildings and institutions. It uses a combination of inherent safety features, including natural convection circulation and negative reactivity coefficients, and engineered features to ensure an extremely safe system. A SLOWPOKE demonstration heating reactor has been constructed in Canada. The unit started operation in July 1987 and is currently undergoing an extensive test program. Since the nuclear heat source is small, operates at atmospheric pressure, and produces hot water below 100 deg. C, the complex high-pressure, and high-temperature systems essential for electricity production are eliminated. As a result, the nuclear heat source can be located close to the load and will require a minimum of operator attention. In this way, a SLOWPOKE Energy System can be considered much like the oil- or natural gas fired furnace it is designed to replace. The extensive use of hot water district heating systems in Hungary offers the opportunity to exploit such simple nuclear systems as base load heat sources without an extensive retrofit of the existing systems. In addition, the studies have concluded that there are many economically attractive sites for 10 MW SLOWPOKE Energy Systems within the existing networks. The low capital investment requirements, coupled with a high degree of localization, even for the first unit, are seen as additional factors that facilitate the transfer of the technology to Hungary. Simple nuclear heat sources, such as the SLOWPOKE Energy System, when applied to the Hungarian district heating systems, offer the prospects of a significant reduction in the dependence on imported fossil fuels in the

    Full Text Available Background: Regularity effect can affect performance in prospective memory (PM, but little is known on the cognitive processes linked to this effect. Moreover, its impacts with regard to aging remain unknown. To our knowledge, this study is the first to examine regularity effect in PM in a lifespan perspective, with a sample of young, intermediate, and older adults. Objective and design: Our study examined the regularity effect in PM in three groups of participants: 28 young adults (18–30, 16 intermediate adults (40–55, and 25 older adults (65–80. The task, adapted from the Virtual Week, was designed to manipulate the regularity of the various activities of daily life that were to be recalled (regular repeated activities vs. irregular non-repeated activities. We examine the role of several cognitive functions including certain dimensions of executive functions (planning, inhibition, shifting, and binding, short-term memory, and retrospective episodic memory to identify those involved in PM, according to regularity and age. Results: A mixed-design ANOVA showed a main effect of task regularity and an interaction between age and regularity: an age-related difference in PM performances was found for irregular activities (older < young, but not for regular activities. All participants recalled more regular activities than irregular ones with no age effect. It appeared that recalling of regular activities only involved planning for both intermediate and older adults, while recalling of irregular ones were linked to planning, inhibition, short-term memory, binding, and retrospective episodic memory. Conclusion: Taken together, our data suggest that planning capacities seem to play a major role in remembering to perform intended actions with advancing age. Furthermore, the age-PM-paradox may be attenuated when the experimental design is adapted by implementing a familiar context through the use of activities of daily living. The clinical

    Great progress has been made in the last 20 years in the study of proton emission from unstable nuclei, but the prospects for additional strides in the next several years are bright. The present main limitations on the study of proton radioactivity are related to the inability to produce copious quantities of nuclides beyond the proton drip line, and the difficulty of measuring proton radioactivity of a mass-separated nucleus in the first few microseconds of its existence. At the Holifield Facility we will attack the second of these limitations by using new signal processing CAMAC modules DGF-4C. Digitizing of the preamplifier signals should enable the analysis of a proton decay occurring at times even less than 1 microsecond after an implant in a strip detector. In the same process, the threshold energy at which we can make measurements will be lowered. These two things will hopefully enable the measurement of lower-energy, but faster decays of isotopes in the 100 Sn region and below. For the latter region, the proton decays crucial for a rp-process scenario are of particular interest (e.g. 69 Br decay). Secondly, for very short-lived species, we plan to make measurements (without residue separation) at points much closer to the target, thus reducing the flight time between the target and detector. As more intense radioactive beams become available, eg. 56 Ni, we will utilize these to produce more neutron-deficient nuclides by use of colder reactions than is possible with stable beams. In some cases where delayed proton emitters are present in the same isobaric chain, the use of the cold reactions with radioactive beams can provide purer samples of the isotope of interest, with a reduction in background from the delayed proton emitters in the same mass chain

    There is a disconnect in the literature between analyses of risky choice based on cumulative prospect theory (CPT) and work on predecisional information processing. One likely reason is that for expectation models (e.g., CPT), it is often assumed that people behaved only as if they conducted the computations leading to the predicted choice and that the models are thus mute regarding information processing. We suggest that key psychological constructs in CPT, such as loss aversion and outcome and probability sensitivity, can be interpreted in terms of attention allocation. In two experiments, we tested hypotheses about specific links between CPT parameters and attentional regularities. Experiment 1 used process tracing to monitor participants' predecisional attention allocation to outcome and probability information. As hypothesized, individual differences in CPT's loss-aversion, outcome-sensitivity, and probability-sensitivity parameters (estimated from participants' choices) were systematically associated with individual differences in attention allocation to outcome and probability information. For instance, loss aversion was associated with the relative attention allocated to loss and gain outcomes, and a more strongly curved weighting function was associated with less attention allocated to probabilities. Experiment 2 manipulated participants' attention to losses or gains, causing systematic differences in CPT's loss-aversion parameter. This result indicates that attention allocation can to some extent cause choice regularities that are captured by CPT. Our findings demonstrate an as-if model's capacity to reflect characteristics of information processing. We suggest that the observed CPT-attention links can be harnessed to inform the development of process models of risky choice. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Full Text Available Forgetting to carry out an intention as planned can have serious consequences in everyday life. People sometimes even forget intentions that they consider as very important. Here, we review the literature on the impact of importance on prospective memory performance. We highlight different methods used to manipulate the importance of a prospective memory task such as providing rewards, importance relative to other ongoing activities, absolute importance, and providing social motives. Moreover, we address the relationship between importance and other factors known to affect prospective memory and ongoing task performance such as type of prospective memory task (time-, event- or activity-based, cognitive loads, and cue focality. Finally, we provide a connection to motivation, we summarize the effects of task importance and we identify important venues for future research.

    Forgetting to carry out an intention as planned can have serious consequences in everyday life. People sometimes even forget intentions that they consider as very important. Here, we review the literature on the impact of importance on prospective memory performance. We highlight different methods used to manipulate the importance of a prospective memory task such as providing rewards, importance relative to other ongoing activities, absolute importance, and providing social motives. Moreover, we address the relationship between importance and other factors known to affect prospective memory and ongoing task performance such as type of prospective memory task (time-, event-, or activity-based), cognitive loads, and processing overlaps. Finally, we provide a connection to motivation, we summarize the effects of task importance and we identify important venues for future research. PMID:25018743

  15. Study of geothermal prospects in the western United States

    Energy Technology Data Exchange (ETDEWEB)

    1976-08-20

    The commercial development potential of 13 underdeveloped geothermal prospects in the Western United States has been examined and the prospects have been ranked in order of relative potential for development on the basis of investment considerations. The following were considered in the ranking: geotechnical and engineering data, energy market accessibility, administrative constraints, and environmental and socio-economic factors. The primary ranking criterion is the unit cost of energy production expected from each prospect. This criterion is obtained principally from expected reservoir temperatures and depths. Secondary criteria are administrative constraints, environmental factors and the quality of the geotechnical data. The Roosevelt, Utah, prospect ranks first in development potential followed in order by Beowawe, Nevada; Coso Hot Springs, California; Long Valley, California; and Brady's Hot Springs, Nevada.

  18. Task Modification and Knowledge Utilization by Korean Prospective Mathematics Teachers.

    Directory of Open Access Journals (Sweden)

    Kyeong-Hwa Lee

    2016-11-01

    Full Text Available It has been asserted that mathematical tasks play a critical role in the teaching and learning of mathematics. Modification of tasks included in intended curriculum materials, such as textbooks, can be an effective activity for prospective teachers to understand the role of mathematical tasks in the teaching and learning of mathematics; designing of new tasks requires more knowledge and experience. This study aims to identify the patterns that Korean prospective mathematics teachers seem to follow when they modify the mathematical tasks in textbooks. Knowledge utilized by prospective teachers while they modify textbook tasks is identified and characterized in order to understand the possible factors that have an impact on Korean prospective mathematics teachers' modification of tasks.

  1. Survey of the results of oil prospecting in Northern Bosnia

    Energy Technology Data Exchange (ETDEWEB)

    Soklic, I

    1972-06-01

    Oil prospecting in N. Bosnia was undertaken from 1898 till 1899, 1929 till 1941 and 1948 till 1963. Besides geological and geophysical prospecting, prospecting drillings have also been performed. Basic data of the results, especially of those in the post-war period, are given. Crude oil in the Tuzla Basin has been found in the Eocene and the middle Miocene-strata of the marine origin, as well as in freshwater Oligomiocene. The accumulation of oil in Pozarnica near Tuzla has the character of unsufficiently drained fissure bed. Test production gave 800 tons of oil before the last war. In Bosanska, Posavina and Semberija, the prospecting wells are located on the highest parts of pre-Neogene relief. (18 refs.)

  15. Using Fuzzy Probability Weights in Cumulative Prospect Theory

    Directory of Open Access Journals (Sweden)

    Užga-Rebrovs Oļegs

    2016-12-01

    Full Text Available During the past years, a rapid growth has been seen in the descriptive approaches to decision choice. As opposed to normative expected utility theory, these approaches are based on the subjective perception of probabilities by the individuals, which takes place in real situations of risky choice. The modelling of this kind of perceptions is made on the basis of probability weighting functions. In cumulative prospect theory, which is the focus of this paper, decision prospect outcome weights are calculated using the obtained probability weights. If the value functions are constructed in the sets of positive and negative outcomes, then, based on the outcome value evaluations and outcome decision weights, generalised evaluations of prospect value are calculated, which are the basis for choosing an optimal prospect.
