R1234yf vs. R134a Flow Boiling Heat Transfer Inside a 3.4 mm ID Microfin Tube  

NASA Astrophysics Data System (ADS)

The refrigerant charge minimization as well as the use of eco-friendly fluids can be considered two of the most important targets for these applications to cope with the new environmental challenges. This paper compares the R1234yf and R134a flow boiling heat transfer and pressure drop measurements inside a small microfin tube with internal diameter at the fin tip of 3.4 mm. This study is carried out in an experimental facility built at the Dipartimento di Ingegneria Industriale of the University of Padova especially designed to study both single and two phase heat transfer processes. The microfin tube is brazed inside a copper plate and electrically heated from the bottom. Several T -type thermocouples are inserted in the wall to measure the temperature distribution during the phase change process. In particular, the experimental measurements were carried out at constant saturation temperature of 30 °C, by varying the refrigerant mass velocity between 190 kg m?2 s?1 and 940 kg m?2 s?1, the vapour quality from 0.2 to 0.99, at different imposed heat fluxes. The two refrigerants are compared considering the values of the two-phase heat transfer coefficient and pressure drop.

Special Fluid Viscous Dampers For The Messina Strait Bridge  

NASA Astrophysics Data System (ADS)

The Messina Strait Bridge would be the world's longest suspension bridge, with a design earthquake characterised by a PGA value of 0.58 g and a distance between the ipocenter and the bridge of 15 km. Said critical structure of course would need a suitable restraint system for traffic braking loads, wind and seismic actions. Each type of load requires a specific behaviour of the restraint system, making its design a big challenge. The restraint system comprises special types of fluid viscous dampers, installed both in longitudinal and transverse direction, both at the towers and at the anchorages. In seismic conditions they behave as viscous dampers, to reduce the forces on the structural elements and the movements of the bridge deck. But in service dynamic conditions, e.g. under traffic or wind load, the devices shall behave like shock transmission units, thus preventing the longitudinal and transverse movements of the deck. FIP Industriale cooperated with the selected General Contractor, a consortium lead by Impregilo, in the design of said viscous dampers. This paper describes the main features of said devices.

Distribution of a Community of Mammals in Relation to Roads and Other Human Disturbances in Gabon, Central Africa  

PubMed Central

Abstract We present the first community-level study of the associations of both roads and other human disturbances with the distribution of mammals in Gabon (central Africa). Our study site was in an oil concession within a littoral mosaic landscape. We conducted surveys along 199 line transects and installed camera traps on 99 of these transects to document mammal presence and abundance. We used generalized linear mixed-effect models to document associations between variables related to the ecosystem (land cover, topography, and hydrology), roads (coating, width of rights of way, condition, type of vehicle used on the road, traffic level, affiliation of users, and general type of road), and other human disturbances (urbanization, agriculture, hunting, logging, gathering, and industrial activities) and the abundance or presence of 17 species or groups of mammals including elephant (Loxodonta cyclotis), buffalo (Syncerus caffer), sitatunga (Tragelaphus spekei), red river hog (Potamochoerus porcus), smaller ungulates, gorilla (Gorilla gorilla), chimpanzee (Pan troglodytes), side-striped jackal (Canis adustus), carnivores, monkeys, and large rodents. Some types of roads and other human disturbances were negatively associated with the abundance or presence of elephants, buffalos, gorillas, sitatungas, some monkeys, and duikers. The pattern of associations of mammals with roads and other human disturbances was diverse and included positive associations with road presence (red river hog, some monkeys, and duikers), agriculture (sitatunga, small carnivores, and large rodents) and industrial activities (sitatunga, red river hog, red duikers, and side-striped jackal). Our results suggest that the community of mammals we studied was mostly affected by hunting, agriculture, and urbanization, which are facilitated by road presence. We recommend increased regulation of agriculture, hunting, and road building in the area. Distribución de una Comunidad de Mamíferos en Relación a Carreteras y Otras Perturbaciones Humanas en Gabón, Africa Central Resumen Presentamos el primer estudio a nivel de comunidad de la relación entre carreteras y otras perturbaciones humanas con la distribución de mamíferos en Gabón (África central). Nuestro sitio de estudio está dentro de una concesión petrolera en un paisaje litoral heterogéneo. Realizamos muestreos a lo largo de 199 transectos lineales e instalamos cámaras trampa en 99 de ellos para documentar la presencia y abundancia de mamíferos. Utilizamos modelos lineales generalizados con efectos mixtos para documentar las asociaciones entre variables relacionadas con el ecosistema (cobertura de suelo, topografía e hidrología), carreteras (tipo de revestimiento, ancho de derecho de vía, condición, tipo de vehículos que utilizan la carretera, nivel de tráfico, afiliación de los usuarios y el tipo general de carretera) y otras perturbaciones humanas (urbanización, agricultura, caza, tala, recolecta y actividades industriales) y la abundancia o presencia de 17 especies o grupos de mamíferos incluyendo elefantes (Loxodonta cyclotis), búfalo (Syncerus caffer), sitatunga (Tragelaphus spekei), cerdo rojo de río (Potomochoerus porcus), ungulados pequeños, gorila (Gorilla gorilla), chimpancé (Pan troglodytes), chacal con rayas a los lados (Canis adustus), carnívoros, monos y roedores de talla grande.

Wind-induced mesoscale circulation off the Ebro delta, NW Mediterranean: a numerical study  

NASA Astrophysics Data System (ADS)

It is well known that the general circulation on the Catalan continental slope is dominated by a quasi-permanent southwestward geostrophic jet associated to the so-called Catalan front [Millot, C., 1987. Circulation in the western Mediterranean sea. Oceanol Acta 10, 143-149; Font, J., Salat, J., Tintoré, J., 1988. Permanent features of the circulation in the Catalan Sea. Oceanol. Acta 9, 51-57]. On the continental shelf, however, the flow is modified by the action of friction which enhances also other nonlinear interactions. Several authors have hypothesized that the shelf circulation is anticyclonic north of the Ebro delta [Salat, J., Manriquez, M., Cruzado, A., 1978. Hidrografia del golfo de Sant Jordi. Campaña Delta (Abril 1970). Investigación Pesquera 42 (2), 255-272; Ballester, A., Castellv?´, J., 1980. Estudio hidrográfico y biológico de las plataformas continentales españolas: I. Efecto de los efluentes de una planta de energ?´a nuclear en el Golfo de San Jorge (Febrero 1975-Octubre 1976). Informes Técnicos del Instituto de Investigaciones Pesqueras 76, 70 pp.]. A quasi-3D finite element code based on the shallow-water equations has been used to explore the effect of several mechanisms which might be responsible for such a local circulation pattern, and in particular of wind. The obtained numerical results suggest that the basic anticyclonic structure of the mean flow is controlled by the bathymetry and that the clockwise-rotating mean flow pattern is not a permanent circulation feature. It is seen that the characteristic local wind stress fields—computed through interpolation of the records of a local network of meteo stations—may `enhance' or `delete' the anticyclonic gyre depending on the sign of their relative vorticity. According to the analysis of a 2-yr record of local wind data, the net contribution of wind events with a duration longer than 24 h is to reinforce the anticyclonic circulation (over 70% of these wind fields supply negative relative vorticity to the study area).

SILER: Seismic-Initiated events risk mitigation in Lead-cooled Reactors  

SciTech Connect

SILER is a Collaborative Project, partially funded by the European Commission, aimed at studying the risk associated to seismic initiated events in Generation IV Heavy Liquid Metal reactors and developing adequate protection measures. The attention is focused on the evaluation of the effects of earthquakes (with particular regards to beyond design seismic events) and to the identification of mitigation strategies, acting both on structures and components design (as well as on the development of seismic isolation devices) which can also have positive effects on economics, leading to an high level of plant design standardization. Attention is also devoted to the identification of plant layout solutions able to avoid risks of radioactive release from both the core and other structures (i.e. the spent fuel storage pools). Specific effort is paid to the development of guidelines and design recommendations for addressing the seismic issue in next generation reactor systems. In addition, consideration will be devoted to transfer the knowledge developed in the project to Generation III advanced systems, in line with the objective of the SNE-TP SRA to support present and future Light Water Reactors and their further development, for which safety issues are key aspects to be addressed. Note, in this respect, that the benefits of base isolation in terms of response to design seismic actions are already widely recognized for Generation III LWRs, along with the possibility of a significant standardization of structural and equipment design. SILER activities started on October 1 st 2011 and are carried out by 18 partners: ENEA (Italy, Coordinator), AREVA NP SAS (France), SCK-CEN (Belgium), FIP Industriale (Italy), MAURER SOHENE (Germany), EC-JRC (Ispra (Italy)), SINTEC (Italy), KTH (Sweden), BOA-BKT (Germany), IDOM (Spain), ANSALDO (Italy), IPUL (Latvia), NUMERIA (Italy), VCE (Austria), SRS (Italy), CEA (France), EA (Spain), NUVIA (France).

Managing for sustainability in an arid climate: lessons learned from 20 years of groundwater management in Arizona, USA  

NASA Astrophysics Data System (ADS)

Substantial progress has been made within central Arizona in moving towards a more sustainable water future, particularly in transitioning the urban demand from a primarily nonrenewable groundwater-based supply to increasing dependence on the Colorado River, Salt River and effluent. Management efforts include a wide range of regulatory and voluntary programs which have had mixed success. The Department of Water Resources has learned a number of key lessons throughout the years, and this paper attempts to establish the water management context and identify those lessons for the benefit of others who may want to evaluate alternative approaches to groundwater management. Themes to be discussed include evaluating water management approaches in a public policy context, the effectiveness of alternative management approaches and the relative merits of regulatory vs. nonregulatory efforts, and the importance of high-quality data in making management decisions. De nets progrès ont été faits dans le centre de l'Arizona pour aller vers une gestion plus durable de l'eau, en particulier en reportant la demande urbaine d'une alimentation basée sur l'eau souterraine primitivement non renouvelable sur une dépendance croissante des rivières Colorado et Salt et des effluents. Les efforts de gestion portent sur une large gamme de programmes de réglementation et d'actions volontaires qui ont réussi. Le Département des Ressources en Eau a appris un certain nombre de leçons clés au cours des années cet article tente d'établir le contexte de gestion de l'eau et d'identifier ces leçons pour le bénéfice de ceux qui cherchent à évaluer des approches alternatives de gestion de l'eau souterraine. Les thèmes à discuter portent sur l'évaluation des approches de gestion de l'eau dans un contexte de politique publique, l'efficacité d'approches alternatives de gestion et les mérites relatifs d'efforts de réglementation par rapport à une absence de réglementation, et l'importance de données de haute qualité dans la prise de décisions de gestion. Resumen Se ha logrado un progreso substancial en el centro de Arizona para conseguir un futuro más sustentable del agua, particularmente al trasladar la demanda urbana desde un suministro basado principalmente en aguas subterráneas no renovables hacia una mayor dependencia de las aguas superficiales de los ríos Colorado y Salado y de los efluentes de aguas depuradas. Los esfuerzos de gestión incluyen un amplio rango de programas legales y voluntarios que han tenido un éxito combinado. El Departamento de Recursos Hídricos ha aprendido diversas lecciones clave a lo largo de los años, y este artículo intenta establecer el contexto de la gestión del agua e identificar lo averiguado para beneficio de terceros que quieran evaluar enfoques alternativos para gestionar las aguas subterráneas. Entre los temas tratados, destaca la evaluación de los enfoques de gestión del agua en un contexto político público, la efectividad de enfoques alternativos de gestión y los méritos relativos de los esfuerzos regulativos y no regulativos, y la importancia de los datos de alta calidad para la toma de decisiones de gestión. Groundwater use in many areas of Arizona greatly exceeds the natural replenishment of the aquifer, so although a portion of the groundwater use is renewable, the majority is not.

NASA Astrophysics Data System (ADS)

Presented in this volume are the Invited Lectures and the Contributed Papers of the Sixth International Workshop on Decoherence, Information, Complexity and Entropy - DICE 2012, held at Castello Pasquini, Castiglioncello (Tuscany), 17-21 September 2012. These proceedings may document to the interested public and to the wider scientific community the stimulating exchange of ideas at the meeting. The number of participants has been steadily growing over the years, reflecting an increasing attraction, if not need, of such conference. Our very intention has always been to bring together leading researchers, advanced students, and renowned scholars from various areas, in order to stimulate new ideas and their exchange across the borders of specialization. In this way, the series of meetings successfully continued from the beginning with DICE 20021, followed by DICE 20042, DICE 20063, DICE 20084, and DICE 20105, Most recently, DICE 2012 brought together more than 120 participants representing more than 30 countries worldwide. It has been a great honour and inspiration to have Professor Yakir Aharonov (Tel Aviv) with us, who presented the opening Keynote Lecture 'The two-vector quantum formalism'. With the overarching theme 'Spacetime - Matter - Quantum Mechanics - from the Planck scale to emergent phenomena', the conference took place in the very pleasant and inspiring atmosphere of Castello Pasquini - in beautiful surroundings, overlooking a piece of Tuscany's coast. The 5-day program covered these major topics: Quantum Mechanics, Foundations and Quantum-Classical Border Quantum-Classical Hybrids and Many-Body Systems Spectral Geometry, Path Integrals and Experiments Quantum -/- Gravity -/- Spacetime Quantum Mechanics on all Scales? A Roundtable Discussion under the theme 'Nuovi orizzonti nella ricerca scientifica. Ci troviamo di fronte ad una rivoluzione scientifica?' formed an integral part of the program. With participation of E Del Giudice (INFN & Università di Milano), F Guerra (Università 'La Sapienza', Roma) and G Vitiello (Università di Salerno), this event traditionally dedicated to the public drew a large audience involved in lively discussions until late. The workshop was organized by L Diósi (Budapest), H-T Elze (Pisa, chair), L Fronzoni (Pisa), J J Halliwell (London), E Prati (Milano) and G Vitiello (Salerno), with most essential help from our conference secretaries L Fratino, N Lampo, I Pozzana, and A Sonnellini, all students from Pisa, and from our former secretaries M Pesce-Rollins and L Baldini.

Urbanization and the groundwater budget, metropolitan Seoul area, Korea  

NASA Astrophysics Data System (ADS)

The city of Seoul is home to more than 10 million people in an area of 605 km2. Groundwater is ed for public water supply and industrial use, and to drain underground facilities and construction sites. Though most tap water is supplied from the Han River, the quantity and quality of groundwater is of great concern to Seoul's citizens, because the use of groundwater for drinking water is continuously increasing. This study identifies the major factors affecting the urban water budget and quality of groundwater in the Seoul area and estimates the urban water budget. These factors include leakage from the municipal water-supply system and sewer systems, precipitation infiltration, water-level fluctuations of the Han River, the subway pumping system, and domestic pumping. The balance between groundwater recharge and discharge is near equilibrium. However, the quality of groundwater and ability to control contaminant fluxes are impeded by sewage infiltration, abandoned landfills, waste dumps, and abandoned wells. Résumé. La ville de Séoul possède une population de plus de 10 millions d'habitants, pour une superficie de 605 km2. Les eaux souterraines sont pompées pour l'eau potable et pour les usages industriels, ainsi que pour drainer les équipements souterrains et les sites en construction. Bien que l'essentiel de l'eau potable provienne de la rivière Han, la quantité et la qualité de l'eau souterraine présentent un grand intérêt pour les habitants de Séoul, parce qu'on utilise de plus en plus l'eau souterraine pour l'eau potable. Cette étude identifie les facteurs principaux qui affectent la qualité de l'eau souterraine dans la région de Séoul et fait l'estimation du bilan d'eau urbaine. Les principaux facteurs affectant le bilan d'eau urbaine et la qualité de l'eau souterraine sont les fuites du réseau d'adduction et du réseau d'égouts, l'infiltration des eaux de précipitation, les fluctuations du niveau de la rivière Han, le réseau de pompage du métro et les pompages privés. Le bilan entre la recharge de la nappe et sa décharge est proche de l'équilibre. Cependant, les infiltrations d'eaux usées, les décharges abandonnées, les décharges d'ordures et les puits abandonnés portent atteinte à la qualité de l'eau souterraine et à la capacité de contrôler les flux de contaminants. Resumen. La ciudad de Seúl tiene más de 10 millones de habitantes en un área de 605 km2. Se bombea aguas subterráneas para abastecimiento urbano y para usos industriales, así como para el drenaje de instalaciones subterráneas y de solares en construcción. Aunque la mayor parte del agua de boca procede del río Han, los ciudadanos de Seúl están muy concienciados por la cantidad y calidad de las aguas subterráneas, ya que su explotación para uso de boca está experimentando un continuo incremento. El presente estudio identifica los factores que más afectan a la calidad de las aguas subterráneas en el área de Seúl y hace una estimación del balance de agua en el territorio urbano. Entre los factores principales que afectan al balance y a la calidad de las aguas subterráneas, se incluye el lixiviado de la red municipal de suministro y de la red de alcantarillado, la infiltración de agua de lluvia, las fluctuaciones del nivel del río Han, el sistema de bombeo del metro y los bombeos domésticos. El balance entre la recarga y la descarga en el acuífero está próximo al equilibrio. Sin embargo, la calidad de las aguas subterráneas y la capacidad de controlar los flujos de contaminación están amenazadas por la infiltración de aguas residuales, vertederos abandonados, depósitos de residuos y pozos abanadonados.

ESO Council Visits First VLT Unit Telescope Structure in Milan  

NASA Astrophysics Data System (ADS)

As the ESO Very Large Telescope (VLT) rapidly takes on shape, Europe has just come one step closer to the realisation of its 556 million DEM astronomical showcase project. Last week, the ESO Council held its semi-annual meeting in Milan (Italy) [1]. During a break in the long agenda list, Council members had the opportunity to visit the Ansaldo factory in the outskirts of this city and to see for the first time the assembled mechanical structure of one of the four 8.2-metre VLT Unit telescopes. This Press Release is accompanied by a photo that shows the ESO Council delegates in front of the giant telescope. After a long climb up the steep staircase to the large Nasmyth platform at the side of the telescope where the astronomical instruments will later be placed, Dr. Peter Creola (Switzerland) , President of the ESO Council and a mechanics expert, grabbed the handrail and surveyed the structure with a professional eye: `I knew it was going to be big, but not that enormous!', he said. Other delegates experienced similar feelings, especially when they watched the 430 tonnes of steel in the 24-metre tall and squat structure turn smoothly and silently around the vertical axis. The Chairman of the ESO Scientific Technical Committee (STC), Dr. Johannes Andersen (Denmark) , summarized his first, close encounter with the VLT by `This is great fun!' and several of his colleague astronomers were soon seen in various corners of the vast structure, engaged in elated discussions about the first scientific investigations to be done with the VLT in two years' time. The VLT Main Structures The visit by Council took place at the invitation of Ansaldo Energia S.p.A. (Genova), EIE-European Industrial Engineering S.r.I. (Venice) and SOIMI-Societa Impianti Industriale S.p.A. (Milan), the three Italian enterprises responsible for the construction of the main structures of the VLT 8.2-metre Unit telescopes. Short speeches were given on this occasion by Drs. Ferruccio Bressani (Ansaldo), Luigi Guiffrida (SOIMI), Gianpietro Marchiori (EIE) and Prof. Massimo Tarenghi (ESO), describing the very successful implementation of this major VLT contract that was awarded by ESO in September 1991 [2]. All speakers praised the good collaboration between ESO and its industrial partners and Prof. Riccardo Giacconi , Director General of ESO, expressed his satisfaction `with the splendid performance of the ESO-Industry team which was bringing us close to the realisation of the premier telescope array in optical ground-based astronomy in the world'. The participants were also pleased to listen to several of the Italian engineers present who commented on the very positive experience of being personally involved in the world's largest telescope project. The VLT telescope structures incorporate many new technological concepts. Thanks to these and careful planning of the many components and their integration, it has been possible to achieve, among others, light weight construction, high mechanical stiffness, good thermal equilibrium with the ambient air (of importance for the seeing during the observations), low electromagnetic emissitivity (i.e. low interference with the sensitive astronomical instruments) and easy maintainability. Of particular interest is also the giant, direct drive system with a diameter of 9 metres and the sophisticated, innovative laser encoder system. In this way, there is no direct contact between the moving parts and the friction during the rotation is kept at an absolute minimum. The Next Steps The ESO VLT project is now entering into a decisive phase and the next years will see an increasing number of telescope parts and instruments from the scientific and industrial laboratories of Europe converging towards the VLT observatory at Cerro Paranal in Chile. It is gratifying that, despite its high degree of complexity and incorporation of a substantial number of new technologies, the project is within schedule and budget. There will be several important milestones in 1996. During the next two months, the mounting of the mechanical structure i

Plan for a groundwater monitoring network in Taiwan  

NASA Astrophysics Data System (ADS)

In Taiwan, rapid economic growth, rising standards of living, and an altered societal structure have in recent years put severe demands on water supplies. Because of its stable quantity and quality, groundwater has long been a reliable source of water for domestic, agricultural, and industrial users, but the establishment of a management program that integrates groundwater and surface-water use has been hampered by the lack of groundwater data. In 1992, the Department of Water Resources (DWR) initiated a program entitled "Groundwater Monitoring Network Plan in Taiwan." Under this program, basic groundwater data, including water-level and water-quality data, are being collected, and a reliable database is being established for the purpose of managing total water resources. This paper introduces the goals, implementation stages, and scope of that plan. The plan calls for constructing 517 hydrogeologic survey stations and 990 groundwater monitoring wells within 17 years. Under this program, water-level fluctuations are continuously monitored, whereas water-quality samples are taken for analysis only at the initial drilling stage and, subsequently, at the time when a monitoring well is being serviced. In 1996, the DWR and the Water Resources Planning Commission were merged to form today's Water Resources Bureau. Résumé A Taïwan, l'expansion économique rapide, l'amélioration des conditions de vie et la transformation de la structure sociale ont provoqué, ces dernières années, une très forte demande en eau. Du fait de sa constance en qualité et en quantité, l'eau souterraine a longtemps été considérée comme une ressource en eau sûre pour les usages domestiques, agricoles et industriels. Mais la mise en place d'un programme de gestion intégrant les utilisations d'eaux souterraines et de surface a été gênée par l'absence de données sur les eaux souterraines. En 1992, le Département des Ressources en Eau a lancé le programme "Plan pour un réseau de suivi des eaux souterraines à Taïwan". D'après ce programme, les données de base concernant les eaux souterraines, comprenant les mesures de niveau et les données de qualité, ont été acquises ; une base de données sûre est en cours d'élaboration, dans le but de gérer l'ensemble des ressources en eau. Cet article présente les buts, les stades de développement et une vue d'ensemble de ce plan. Le plan impose la mise en place de 517 stations de mesures hydrogéologiques et de 990 piézomètres en 17 ans. Selon ce programme, les variations du niveau des nappes doivent être suivies en continu, tandis que des échantillons pour la qualité de l'eau seront prélevés pour analyses uniquement au cours de la phase de foration, puis au moment de la mise en service des piézomètres. En 1996, le Département des Ressources en Eau et la Commission de Planification des Ressources en Eau ont été réunis pour former l'actuel Bureau des Ressources en Eau. Resumen En Taiwan, el rápido crecimiento económico, el aumento en el nivel de vida y los cambios sociales en los últimos años han resultado en un aumento en la demanda de agua. Por su estabilidad en términos de cantidad y calidad, las aguas subterráneas han sido durante años la fuente de agua para usos domésticos, agrícolas e industriales. En los últimos años, sin embargo, el establecimiento de un programa de gestión conjunta de aguas superficiales y subterráneas se ha visto comprometido por la falta de datos correspondientes a estas últimas. En 1992, el Departamento de Recursos de Agua (DWR) inició un programa titulado "Plan de Red de Control de Aguas Subterráneas en Taiwan". Bajo este programa, se están recogiendo datos básicos, incluyendo niveles piezométricos y datos de calidad, y se está construyendo una base de datos con el propósito de gestionar los recursos de agua totales. Este artículo presenta el marco, los objetivos y el estado de implantación del plan, que pretende la construcción de 517 estaciones de medida hidrogeológicas y 990 pozos de obs
