  1. TeleMEDiana: telesurgery and telemedicine by satellite and the Internet

    NASA Astrophysics Data System (ADS)

    Dobrosavljevic, Sneja; Welter, Roger

    2002-08-01

    The rapid development of technology and its integration into the spectrum of medical care are creating a pressing need for healthcare professionals to continuously update their knowledge and skills. In view of these needs the European Association of Visceral Surgery (AECV) which had been a platform for medical congresses in Luxembourg (1988, 1992, 1995, 1998) has developed TeleMEDiana a new broadband communication service introducing standards of excellence in Continuous Medical Education.TeleMEDiana broadcast a daily program with pedagogically enhanced video content in a number of therapeutic areas to MD's, professors and students in hospitals, universities and research centers. The educational programs are provided by leading European hospitals which have joined the TeleMEDiana Scientific Network TSN. The scientific integrity is certified by an international committee composed of recognized pioneers. Committed to deliver high resolution video streaming, TeleMEDiana has set up and successfully tested a new platform built on secure and cost-efficient satellite operator SES-ASTRA complemented by the Internet and can deliver programs to any workplace equipped with satellite dishes and high-quality set-top boxes. Telemediana offers herewith an optimal collaboration and dissemination platform to decisive players involved in Continuing Medical Education.

  2. Bloedite sedimentation in a seasonally dry saline lake (Salada Mediana, Spain)

    NASA Astrophysics Data System (ADS)

    Mees, Florias; Castañeda, Carmen; Herrero, Juan; Van Ranst, Eric

    2011-06-01

    Salt crusts covering the surface of the Salada Mediana, a seasonally dry saline lake in northern Spain, consist predominantly of bloedite (Na 2Mg(SO 4) 2.4H 2O). Microscopic features of the crust were investigated to understand processes of bloedite sedimentation. This study was combined with satellite and airborne observations, revealing asymmetrical concentric and parallel-linear patterns, related to wind action. Gypsum (CaSO 4.H 2O) and glauberite (Na 2Ca(SO 4) 2) in the calcareous sediments below the crust, and abundant eugsterite (Na 4Ca(SO 4) 3.2H 2O) along the base of the crust, largely formed at a different stage than bloedite. The main part of the crust consists predominantly of coarse-crystalline xenotopic-hypidiotopic bloedite, but fan-like aggregates with downward widening, radial aggregates, surface layers with vertically aligned elongated crystals, and partially epitaxial coatings occur as well. The upper part of the crust is marked by a bloedite-thenardite (Na 2SO 4) association, recording a change in brine composition that is not in agreement with results of modelling of local brine evolution. A thin fine-grained thenardite-dominated surface formed in part by subaqueous settling of crystals, but there are also indications for development by transformation of bloedite. Surface features include fan-like bloedite aggregates with upward widening, formed by bottom growth. Overall, the Salada Mediana crusts record a complex history of bloedite and thenardite precipitation by various processes.

  3. Errores fotométricos debido al uso del filtro anular de mediana en imágenes CCD

    NASA Astrophysics Data System (ADS)

    Gil-Hutton, R.; Cañada, M.; Noel, N.

    El filtro anular de mediana tiene la importante propiedad de tener una escala claramente definida, lo que permite remover de una imagen CCD todos los objetos con tamaños menores a esta escala, independientemente de su morfología particular, y reemplazarlos por el correspondiente ``background" local. Este filtro es de gran utilidad para remover gradientes de fondo, ``fringing" y halos de objetos extendidos mediante el simple procedimiento de restar a la imagen original una imagen filtrada, repitiendo el proceso las veces que sea necesario. En este trabajo se presentan resultados sobre los errores que introduce este filtro en la fotometría de objetos con diferente relación S/N y su aplicación a imágenes con gradientes de fondo y ``fringing".

    Hypercoordination of main-group elements such as the heavier Group 14 elements (silicon, germanium, tin, and lead) usually requires strong electron-withdrawing ligands and/or donating groups. Herein, we present the synthesis and characterization of two hexaaryltin(IV) dianions in form of their dilithium salts [Li2(thf)2{Sn(2-py(Me))6}] (py(Me)=C5H3N-5-Me) (2) and [Li2{Sn(2-py(OtBu))6}] (py(OtBu)=C5H3N-6-OtBu) (3). Both complexes are stable in the solid state and solution under inert conditions. Theoretical investigations of compound 2 reveal a significant valence 5s-orbital contribution of the tin atom forming six strongly polarized tin-carbon bonds. PMID:25314245

El método consiste en construir un mapa con los ángulos de inclinación de las franjas en cada punto de la imagen. Este mapa es ulteriormente utilizado para alinear con el patrón de interferencia una ventana estrecha, sobre la que se aplica un filtro de mediana. Este procedimiento permite eliminar la mayor parte del ruido del patrón de fringing sin destruirlo.

  14. Leveraging the Zachman framework implementation using action - research methodology - a case study: aligning the enterprise architecture and the business goals

    NASA Astrophysics Data System (ADS)

    Nogueira, Juan Manuel; Romero, David; Espadas, Javier; Molina, Arturo

    2013-02-01

    With the emergence of new enterprise models, such as technology-based enterprises, and the large quantity of information generated through technological advances, the Zachman framework continues to represent a modelling tool of great utility and value to construct an enterprise architecture (EA) that can integrate and align the IT infrastructure and business goals. Nevertheless, implementing an EA requires an important effort within an enterprise. Small technology-based enterprises and start-ups can take advantage of EAs and frameworks but, because these enterprises have limited resources to allocate for this task, an enterprise framework implementation is not feasible in most cases. This article proposes a new methodology based on action-research for the implementation of the business, system and technology models of the Zachman framework to assist and facilitate its implementation. Following the explanation of cycles of the proposed methodology, a case study is presented to illustrate the results of implementing the Zachman framework in a technology-based enterprise: PyME CREATIVA, using action-research approach.

    2004-06-01

    This study aims to observe the morphological characteristics of the uropygial gland (Glandula uropygialis), specifically the arterial vascularization, in rock partridges (Alectoris graeca) living in Turkey. Coloured-latex-injected animals were dissected and the gland and related arteries were observed. Mostly, the fourth paired caudal segmental arteries (Aa. segmentales caudales) arising from the median caudal artery (A. mediana caudae) were specified as the uropygial gland arteries. These arteries, in turn, gave the following rami: the muscular ramus (Ramus muscularis) to the levator coccygeus and lateral caudal muscles, the lateral ramus (Ramus lateralis) to the lateral coccygeus muscle and a small ventro-lateral division of the caudal component of the gland, and the medial rami (Ramus medialis) to the dorsal surface of the gland.

    2010-05-01

    Lipid membranes are a subject of contemporary interdisciplinary studies at the junction of biology, biophysics, pharmacology, and bionanotechnology. The results of the structural studies of several types of lipid membranes by the lamellar and lateral diffraction of X-ray synchrotron radiation are presented. The experiments were performed at the Mediana and DICSI stations of the Siberia-2 synchrotron radiation source at the Russian Research Center Kurchatov Institute. The data obtained are compared with the results of studying lipid membranes at the small-angle scattering beamlines D22 and D24 at LURE (France) and at the A2 beamline at DESY (Germany). The parameters of the DICSI station are shown to meet the basic requirements for the structural study of lipid systems, which are of fundamental and applied interest.

    Introducción: la rehabilitación de la alimentación por vía oral (RVO) es compleja en pacientes que han recibido nutrición enteral (NE) prolongada. Objetivo: describir este proceso en niños con enfermedades respiratorias crónicas y sonda nasoenteral (SNE) o gastrostomía (GT).Pacientes y métodos: estudio retrospectivo con revisión de registros clínicos de niños con NE mayor a dos meses, ingresados entre 2005 y 2014 al Hospital Josefina Martínez.Resultados: Se incluyeron 116 pacientes, con mediana de edad 10 meses (Rango: 3 a 101), 56% hombres. Diagnóstico: 34,5% Daño pulmonar crónico postinfeccioso (DPC), 29,3% Insuficiencia respiratoria por enfermedad neuromuscular, 19% Displasia broncopulmonar y 17,2% enfermedad de la vía aérea. Con traqueostomía: 82,8%. Eran usuarios de GT 89,7% y de SNG 10,3%, instaladas con mediana de edad 6 meses (0 a 74), por ingesta insuficiente (6,6%) o trastorno de deglución (92,4%). Del grupo total, 36,2% (42/116) tenía indicación de RVO, los cuales habían recibido NE durante 12,2 meses (2 a 41); de estos 50% (21/42) logró alimentarse exclusivamente por vía oral (91% SNG y 35,4% GT, Chi2 p = 0,023), 14% parcialmente y 36% no lo logró. El tiempo para lograr la vía oral exclusiva fue de 9,75 meses (0,5 a 47), sin diferencia por edad, sexo, vía de acceso, duración NE ni presencia de enfermedad neurológica.Conclusión: en pacientes con enfermedades respiratorias crónicas graves y NE prolongada, la RVO es un proceso lento pero posible: 64% lo logra de modo completo o parcial.

  18. Comparative brain morphology of Neotropical parrots (Aves, Psittaciformes) inferred from virtual 3D endocasts.

    Carril, Julieta; Tambussi, Claudia Patricia; Degrange, Federico Javier; Benitez Saldivar, María Juliana; Picasso, Mariana Beatriz Julieta

    2016-08-01

    Psittaciformes are a very diverse group of non-passerine birds, with advanced cognitive abilities and highly developed locomotor and feeding behaviours. Using computed tomography and three-dimensional (3D) visualization software, the endocasts of 14 extant Neotropical parrots were reconstructed, with the aim of analysing, comparing and exploring the morphology of the brain within the clade. A 3D geomorphometric analysis was performed, and the encephalization quotient (EQ) was calculated. Brain morphology character states were traced onto a Psittaciformes tree in order to facilitate interpretation of morphological traits in a phylogenetic context. Our results indicate that: (i) there are two conspicuously distinct brain morphologies, one considered walnut type (quadrangular and wider than long) and the other rounded (narrower and rostrally tapered); (ii) Psittaciformes possess a noticeable notch between hemisphaeria that divides the bulbus olfactorius; (iii) the plesiomorphic and most frequently observed characteristics of Neotropical parrots are a rostrally tapered telencephalon in dorsal view, distinctly enlarged dorsal expansion of the eminentia sagittalis and conspicuous fissura mediana; (iv) there is a positive correlation between body mass and brain volume; (v) psittacids are characterized by high EQ values that suggest high brain volumes in relation to their body masses; and (vi) the endocranial morphology of the Psittaciformes as a whole is distinctive relative to other birds. This new knowledge of brain morphology offers much potential for further insight in paleoneurological, phylogenetic and evolutionary studies. PMID:26053196

    Thermal place names were compiled from all 1:50,000 topographic quadrangle maps for the Republic of Honduras as of July 1986, from other published maps, and from several sources of unpublished data. Known hot spring sites include those visited by Empresa Nacional de Energia Electrica (Honduras) geologists, sites visited by Los Alamos geologists in 1985, and other sites known to R.C. Finch. The number of known hot spring sites in Honduras with temperatures >30/sup 0/C is 125. In addition, 56 thermal sites are suspected on the basis of thermal place names. The total number of geothermal sites, known and suspected, is 181.

    The paper analyzes different approaches for the calculation of available water resources the under influence of CC, for cases of drinking water sources in the alluviums of the Sava River (Belgrade GW source)and Nišava River (Mediana GW source). Different types of analyzed sources (bank-filtered and artificially recharged) required different approaches, adjusted to the specific characteristics. The Belgrade GW source (capacity of 4-5 m3/s), is comprised of 99 horizontal wells and over 40 tube wells positioned on the 50 km on the alluvial plain of the most downstream Sava River banks. Deep parts of the water bearing complex are comprised of river-lacustrine polycyclic sediments (from sandy-gravels to silts), while the upper part are alluvial sediments. Main recharge stems from the Sava River by bank filtration process, while due to the layering of the aquifer, recharge from the hinterland in some river bank sections reaches up to 30 %. Test area covers 240km2, of Sava river valley. Future water availability has to be calculated according to the "new" -expected boundary conditions, vertical water balance on the test area and "estimated" river water fluctuations. The artificially-recharged GW source "Mediana" provides water supply to the City of Niš, as one of 6 water supply sources. The concept of this groundwater source is based on surface water abstraction from the Nišava River (catchement area is 4,086 km2 totally, where 1,096 km2 is in Bulgaria), which is transported to infiltration lakes after pre-treatment process. Once in the infiltration lake, the water is infiltrated into the aquifer and abstracted by wells, or collected by a drainage system. This site was used for the analysis of the impacts of climate changes on the discharge of Nisava River, since it feeds aquifer through infiltration lakes (approx. 95-98%) after surface water pretreatment. Estimation of available water resources was done for period until 2100 for A1B climate scenario. Climate

    Introducción: la cuantificación y registro de la ingesta alimentaria del paciente hospitalizado es clave dentro del plan de cuidado nutricional. Objetivo: evaluar la validez de un cuestionario semicuantitativo de valoración del consumo comparado con una técnica de registro de alimentos por observación y pesada de los platos incluidos en la dieta hospitalaria. Métodos: estudio transversal realizado en condiciones de práctica clínica habitual. Las técnicas de valoración del consumo que se compararon fueron un registro por doble pesada y un cuestionario semicuantitativo por observación de la ingesta de cinco categorías (todo [> 80%], casi todo [80-60%], la mitad [60-40%], casi nada [40-20%] o nada [< 20%]), ambas realizadas por un dietista-nutricionista. La comparación entre ambas herramientas fue realizada con el índice kappa con ponderación cuadrática e intervalo de confianza del 95%. Resultados: fueron realizadas un total de 1.980 valoraciones. Se observó con el cuestionario semicuantitativo que en el 50% de los casos se ingirió todo, en el 19% casi todo, en el 13% la mitad, en el 9% menos de la mitad y en el 9% nada. La mediana de la ingesta por doble pesada de alimentos fue de 76,8 (RIC 45,8)%. Se observó que existió un acuerdo satisfactorio entre la técnica de doble pesada y la valoración visual del consumo con un valor κ = 0,907 (IC 95% 0,894-0,925). Conclusión: la escala visual empleada en este estudio permite cuantificar la ingesta real del paciente de forma precisa y adecuada por personal cualificado.

    In response to a request from the Pan American Health Organization (PAHO), an investigation was begun into possible exposures to heavy metals and sulfur-dioxide at Empresa Metalurigica Vinto, a large tin smelter near Oruro, Bolivia. Fifteen workers were selected for exposure monitoring. Of the 15, 14 had exposures greater than the NIOSH Recommended Exposure Limit or the OSHA Permissible Exposure Level to arsentic; 11 had hazardous exposures to cadmium, and eight had hazardous exposures to sulfur-dioxide. Surfaces throughout the facility were highly contaminated with heavy metals. Fifteen workers participated in biological monitoring studies. The median value for urinary arsenic (UA) was 78 micrograms per gram creatinine. Nine of the 15 workers had UA levels exceeding the American Conference of Governmental Industrial Hygienists Biological Exposure Index. The median blood lead level was 19 micrograms per deciliter.

    overpotential of 1.0 V, without apparent loss in activity. Replacing the oxo moiety with a disulfide affords [(PY5Me2)MoS2](2+), which bears a molecular MoS2 triangle that structurally and functionally mimics bulk molybdenum disulfide, improving the catalytic activity for water reduction. In water buffered to pH 3, catalysis by [(PY5Me2)MoS2](2+) onsets at 400 mV of overpotential, whereas [(PY5Me2)MoO](2+) requires an additional 300 mV of driving force to operate at the same current density. Metalation of the PY5Me2 ligand with an appropriate Co(ii) source also furnishes electrocatalysts that are active in water. Importantly, the onset of catalysis by the [(PY5Me2)Co(H2O)](2+) series is anodically shifted by introducing electron-withdrawing functional groups on the ligand. With the [(bpy2PYMe)Co(CF3SO3)](1+) system, we showed that introducing a redox-active moiety can facilitate the electro- and photochemical reduction of protons from weak acids such as acetic acid or water. Using a high-throughput photochemical reactor, we examined the structure-reactivity relationship of a series of cobalt(ii) complexes. Taken together, these findings set the stage for the broader application of polypyridyl systems to catalysis under environmentally benign aqueous conditions. PMID:26101803

    The Idaho National Laboratory (INL) in collaboration with the U.S. Geological Survey (USGS) with the assistance of the Empresa de Pesquisa Energetica (EPE) and the Agencia Nacional de Energia Electrica (ANEEL) has performed a comprehensive assessment of the hydropower potential of all Brazilian natural streams. The methodology by which the assessment was performed is described. The results of the assessment are presented including an estimate of the hydropower potential for all of Brazil, and the spatial distribution of hydropower potential thus providing results on a state by state basis. The assessment results have been incorporated into a geographic information system (GIS) application for the Internet called the Virtual Hydropower Prospector do Brasil. VHP do Brasil displays potential hydropower sites on a map of Brazil in the context of topography and hydrography, existing power and transportation infrastructure, populated places and political boundaries, and land use. The features of the application, which includes tools for finding and selecting potential hydropower sites and other features and displaying their attributes, is fully described.

    All regions of Brazil are potential areas for growing tropical fruits. As this country is already a great producer and exporter of tropical fruits, ionizing radiation has been the subject of studies in many commodities. An important project has been carried out to increase the commercial use of gamma radiation in our country. Instituto de Pesquisas Energeticas e Nucleares (IPEN)-CNEN/SP together with field producers in northeast region and partners like International Atomic Energy Agency (IAEA), CIC, Empresa Brasileira Pesquisa na Agricultura (EMBRAPA) joined to demonstrate this technology, its application and commercial feasibility. The objective of this study is to show advances in feasibility demonstrate the quality of the irradiated fruits in an international consignment from Brazil to Canada. In this work, Tommy Atkins mangoes harvested in northeast region of Brazil were sent to Canada. The fruits were treated in a gamma irradiation facility at doses 0.4 and 1.0 kGy. The control group was submitted to hydrothermal treatment (46 °C for 110 min). The fruits were stored at 11 °C for 10 days until the international transportation and kept at an environmental condition (22 °C) for 12 days, where their physical-chemical and sensorial properties were evaluated. The financial part of the feasibility study covers the scope of the investment, including the net working capital and production costs.

    Foster Wheeler Power Systems Inc., and its partners--Petrox SA Refineria de Petroleo and Empresa Nacional de Petroleo (ENAP), the Chilean national oil company--closed on the financing of Petropower Energia Limitada, a $237 million financed combination delayed coker-cogeneration facility. The facility is now under construction adjacent to Petrox`s 84,000 b/d Talcahuano refinery, near Concepcion. In addition to the low interest rate of 7.36%--only 170 basis points over the 10 year US Treasury yield--the project was rated investment-grade by Standard and Poor`s. The Petropower project also has the distinction of having the longest term--18 years--for any project financing in Latin America. The project is unique in other ways: it is the Republic of Chile`s first public/private partnership and also the first project to combine petroleum coking technology with cogeneration technology in a single project financing. The paper discusses risk assumption, the Petropower project, organization, delayed coker facility, hydrotreater unit, cogeneration facility, environmental assessment, Chile`s changing market, and project benefit.

    CETREL--Empresa de Protecao Ambiental, is an environmental engineering company, which is owned by the member companies in the Camacari Petrochemical Complex, the largest petrochemical complex in Brazil. CETREL operates a centralized waste treatment plant, treatment and disposal facilities, an incineration unit, groundwater monitoring and air quality monitoring networks. The air monitoring network was designed based on mathematical modeling, and the results showed that the monoitoring of hydrocarbons is important not just within the complex but also at the area surrounding the complex. There are presently no regulations for hydrocarbons in Brazil, however they are monitored due to concerns about health problems arising from human exposure. The network has eight multiparameter monitoring stations, located at the villages nearby, where hydrocarbons are sampled with Summa canisters and subsequently analyzed with a GC/MS, using a Cryogenic trap at the interface. The open-path FTIR is used to monitor at the individual plants and in the areas in between because it is more efficient and costs less than it would to attempt to achieve the same level of coverage using the canisters. Ten locations were selected based on mathematical modeling and knowledge of the likely emission sources. Since August 1993, there have been five different measurement campaigns.

    Integrated, long-term risk management in the water sector is poorly developed. Whilst scenario planning has been applied to singular issues (e.g. climate change), it often misses a link to risk management because the likelihood of impacts in the long-term are frequently unaccounted for in these analyses. Here we apply the morphological approach to scenario development for a case study utility, Empresa Portuguesa das Águas Livres (EPAL). A baseline portfolio of strategic risks threatening the achievement of EPAL's corporate objectives was evolved through the lens of three future scenarios, 'water scarcity', 'financial resource scarcity' and 'strong economic growth', built on drivers such as climate, demographic, economic, regulatory and technological changes and validated through a set of expert workshops. The results represent how the baseline set of risks might develop over a 30 year period, allowing threats and opportunities to be identified and enabling strategies for master plans to be devised. We believe this to be the first combined use of risk and futures methods applied to a portfolio of strategic risks in the water utility sector. PMID:26584343

    As part of a research contract jointly funded by the Commission of the European Communities (CEC) and Empresa Nacional de Residuos Radiactivos S.A. (Enresa, Spain), the Instituto de Medioambiente of the CIEMAT Research Centre and Intera (UK) are developing and testing a general methodology (SACO) to assess the post-disposal environmental impact produced by waste disposal practices. The scope of the methodology includes toxic, radioactive and mixed hazardous wastes. The term toxic is interpreted broadly to include any kind of liquid or solid non-radioactive waste which could give rise to some detrimental environmental effects post-disposal. Radioactive wastes considered include the full range from low to high level solid wastes arising inside and outside the nuclear power industry. Mixed hazardous waste is taken to be waste presenting both radioactive and other toxic hazard potential. In this paper SACO version 1.0 methodology is presented and it is applied to the assessment of the impact of shallow and deep disposal of waste.

    The spatiotemporal development of Trichel pulses in oxygen between a spherical electrode and a grounded plane has been simulated using a fluid approximation that incorporates the plasma chemistry of the electrical discharge. Elementary plasma processes, such as ionization, electron attachment, electron detachment, recombination between ions and chemical reactions between neutral species, are all included in a chemical model consisting of 55 reactions between 8 different species (electrons, O2+,O2-,O3-,O-, O2, O, O3). Secondary emission at the cathode by the impact of positive ions and photons is also considered. The spatial distribution of species is computed in three dimensions (2D-axysimmetrical) by solving Poisson's equation for the electric field and the continuity equations for the species, with the inclusion of the chemical gain/loss rate due to the particle interaction. The results of the simulation reveal the interplay between the different negative ions during the development of every Trichel pulse, and the rate of production of atomic oxygen and ozone by the corona discharge.

    Semianalytical approximate solutions of the spatial distribution of electric field and electron and ion densities have been obtained by solving Poisson's equations and the continuity equations for the charged species along the Laplacian field lines. The need to iterate for the correct value of space charge on the corona electrode has been eliminated by using the corona current distribution over the grounded plane derived by Deutsch, which predicts a cos m θ law similar to Warburg's law. Based on the results of the approximated model, a parametric study of the influence of gas pressure, the corona wire radius, and the inter-electrode wire-plate separation has been carried out. Also, the approximate solutions of the electron number density has been combined with a simplified plasma chemistry model in order to compute the ozone density generated by the corona discharge in the presence of a gas flow.

    This paper is a review and summary of the core drilling operations component of the Honduras Geothermal Resource Development Project at the Platanares geothermal prospect in Honduras, Central America. Three intermediate depth (428 to 679 m) coreholes are the first continuously cored geothermal exploration boreholes in Honduras. These coring operations are part of the Central America Energy Resource Project (CAERP) effort funded by the Agency for International Development (AID) and implemented by the Los Alamos National Laboratory (Los Alamos) in cooperation with the Empresa Nacional de Energia Electrica (ENEE) and the United States Geological Survey (USGS). This report emphasizes coring operations with reference to the stratigraphy, thermal gradient, and flow test data of the boreholes. The primary objectives of this coring effort were (1) to obtain quantitative information on the temperature distribution as a function of depth, (2) to recover fluids associated with the geothermal reservoir, (3) to recover 75% or better core from the subsurface rock units, and (4) to drill into the subsurface rock as deeply as possible in order to get information on potential reservoir rocks, fracture density, permeabilities, and alteration histories of the rock units beneath the site. The three exploration coreholes drilled to depths of 650, 428 and 679 m, respectively, encountered several hot water entries. Coring operations and associated testing began in mid-October 1986 and were completed at the end of June 1987.

    Vineyard soils are frequently polluted with high concentrations of copper due application of copper sulfate in order to control fungal diseases. Bioremediation is an efficient process for the treatment of contaminated sites. Efficient copper sorption bacteria can be used for bioremoval of copper from contaminated sites. In this study, a total of 106 copper resistant bacteria were examined for resistance to copper toxicity and biosorption of copper. Eighty isolates (45 from vineyard Mollisol, 35 from Inceptisol) were obtained from EMBRAPA (Empresa Brasileira de Pesquisa Agropecuária) experimental station, Bento Gonçalves, RS, Brazil (29°09′53.92″S and 51°31′39.40″W) and 26 were obtained from copper mining waste from Caçapava do Sul, RS, Brazil (30°29′43.48″S and 53′32′37.87W). Based on resistance to copper toxicity and biosorption, 15 isolates were identified by 16S rRNA gene sequencing. Maximal copper resistance and biosorption at high copper concentration were observed with isolate N2 which removed 80 mg L−1 in 24 h. Contrarily isolate N11 (Bacillus pumilus) displayed the highest specific copper biosorption (121.82 mg/L/OD unit in 24 h). GenBank MEGABLAST analysis revealed that isolate N2 is 99% similar to Staphylococcus pasteuri. Results indicate that several of our isolates have potential use for bioremediation treatment of vineyards soils and mining waste contaminated with high copper concentration. PMID:24031606

    Construction of the Republic of Chile`s first public/private industrial partnership project is well under way. Ground was broken for the $232-million Petropower Energia Limitada project early this year, shortly after the final contract between the parties - Foster Wheeler Power Systems, Inc. (FWPS); Petrox S.A. Refineria de Petroleo and Empresa Nacional del Petroleo (ENAP) - was signed. The Petropower project, located adjacent to Petrox`s 84,000-b/d refinery in Talcahuano, represents the first project ever to combine petroleum coking technology with cogeneration technology in a single project financing. Petropower is 85% owned by FWPS, 7.5% by ENAP, the Chilean national oil company and parent of Petrox S.A. When completed in mid-1998, the Petropower project will enable Petrox to refine heavier crudes and enhance the refinery`s flexibility and economics. The project will consist of a delayed coking facility (a 12,000-b/d delayed coking unit and a 7,000-b/d hydrotreating plant) and a 67-MW (59 MW net) cogeneration plant. The coke produced will fuel a Foster Wheeler proprietary-design circulating fluidized-bed (CFB) boiler which will generate all the high-pressure steam and electric power needs of the Petrox refinery. This unit will be the first circulating fluidized-bed boiler to be built in Latin America. The cogeneration facility, using limestone as a reagent and equipped with a baghouse, will control SO{sub x} emissions from combustion of the green coke fuel and easily meet all Chilean environmental standards. Moreover, by constructing the cogeneration facility, Petrox will not have to proceed with capital improvements to existing facilities to ensure a reliable source of steam and electricity, resulting in substantial savings for Petrox. The cogeneration plant provides a permanent {open_quotes}disposal{close_quotes} for all coke produced by the delayed coker, thereby solving any future problems of unwanted or excess coke.

    1994-12-31

    This paper focuses on predictive modelling capacity for post-disposal safety assessments of land-based disposal facilities, illustrated by presentation of the development and application of a comprehensive, yet practicable, assessment framework. The issues addressed include: (1) land-based disposal practice, (2) the conceptual and mathematical representation of processes leading to release, migration and accumulation of contaminants, (3) the identification and evaluation of relevant assessment end-points, including human health, health of non-human biota and eco-systems, and property and resource effects, (4) the gap between data requirements and data availability, and (5) the application of results in decision making, given the uncertainties in assessment results and the difficulty of comparing qualitatively different impacts arising in different temporal and spatial scales. The paper illustrates the issues with examples based on disposal of metals and radionuclides to shallow facilities. The types of disposal facility considered include features consistent with facilities for radioactive wastes as well as other types of design more typical of hazardous wastes. The intention is to raise the question of whether radioactive and other hazardous wastes are being consistently managed, and to show that assessment methods are being developed which can provide quantitative information on the levels of environmental impact as well as a consistent approach for different types of waste, such methods can then be applied to mixed hazardous wastes contained radionuclides as well as other contaminants. The remaining question is whether the will exists to employ them. The discussion and worked illustrations are based on a methodology developed and being extended within the current European Atomic Energy Community`s cost-sharing research program on radioactive waste management and disposal, with co-funding support from Empresa Nacional de Residuous Radiactivos SA, Spain.

  20. Petroleum possibilities in continental margin off central Chile

    The continental margin off central Chile, from Valparaiso to Valdivia, encompassing an area of 100,000 km/sup 2/, has been the target of exploratory activity by Empresa Nacional del Petroleo since 1970. Exploratory drilling began in 1972. By August 1984, total exploratory efforts had resulted in drilling 14 offshore wells and acquiring 12,130 km of seismic reflection lines. A biogenic gas accumulation was discovered in the F well. Because these attempts to find oil were unsuccessful and because drilling costs have escalated, exploratory activities have been curtailed. Forearc basins off central Chile are characterized by low geothermal gradient and a sedimentary filling of Cretaceous and Tertiary strata. Tertiary sequences are characterized by low organic carbon content, immature humic-type organic matter, and a biogenic gas potential. Cretaceous sequences are characterized by higher organic carbon content, good reservoir rocks, and fair to good source rocks. The organic matter is sapropelic, with vitrinite and liptinites, and is favorable for oil and gas generation. Seismic and well data suggest that Mesozoic and Cenozoic sedimentary rock sequences filling the basins (more than 4000 m thick at the shelf edge) extend 40-70 km beyond the present shelf edge. Mesozoic rocks deposited on the slope may generate petroleum and gas that could migrate upslope and accumulate in traps associated with the faulted basement highs and graben-type depressions existing at the shelf edge. This geologic setting favors the development of large petroleum accumulations along the shelf edge and graben on the sedimentary basins off central Chile.

    Decisiones de Manejo Resumen Las revisiones sistemáticas resumen integralmente la evidencia sobre la efectividad de las intervenciones de conservación. Investigamos la contribución de las decisiones de manejo hechas por este creciente cuerpo de literatura. Identificamos 43 revisiones sistemáticas de evidencia de conservación, 23 de las cuales hicieron algunas conclusiones concretas relevantes al manejo. La mayoría de las revisiones se dirigían a intervenciones de conservación relevantes a las decisiones políticas; sólo el 35% consideraba intervenciones de manejo sobre-la-causa prácticas. La mayoría de las revisiones cubrieron solo una pequeña fracción de la amplitud geográfica y taxonómica a la que buscaban dirigirse (mediana = 13% de los países relevantes y 16% de los taxones relevantes). La probabilidad de que las revisiones tuvieran por lo menos algunas implicaciones para el manejo tendió a incrementar conforme la cobertura geográfica incrementaba y a declinar conforme aumentaba la amplitud taxonómica. Estos resultados sugieren que la amplitud de una revisión taxonómica requiere de una consideración cuidadosa. Las revisiones identificaron una media de 312 estudios primarios relevantes pero excluyeron 88% de estos por deficiencias en el diseño o fallas para coincidir con otros criterios de inclusión. Las revisiones resumieron en promedio 248 juegos de datos y 112 años de actividad de investigación, pero la probabilidad de que sus resultados tuvieran por lo menos algunas implicaciones para el manejo no incrementaron mientras la cantidad de investigación primaria resumida aumentaba. En algunos casos, las conclusiones fueron elusivas a pesar de la inclusión de cientos de conjuntos de datos y años de actividad de investigación acumulada. Las revisiones sistemáticas son una parte importante del juego de herramientas en la toma de decisiones de conservación, aunque consideramos que los beneficios de las revisiones sistemáticas podrían ser

    By considering that the climate of Northeast Brazil (NEB) has distinct wet and dry seasons, the mixed radix fast Fourier transform (mrFFT) algorithm, developed at the National Aerospace Centre of the Netherlands, was applied to a monthly Normalized Difference Vegetation Index (NDVI) time series from July 1981 to June 1993, to generate phase, amplitude and mean NDVI data using a 1-year frequency in order to improve the analysis of its spatial variation.The NDVI mean values varied from >0.7, which occurred in northwest and southeast regions, to <0.3 in the northeast and 0.4 in the southwest regions of the NEB. The 90° phase month at its maximum amplitude occurred in August and was observed in both southeastern and northwestern coasts, located at 10.5°S-37.5°W and 4°S-46°W, respectively. It changed rapidly from August, June to May, moved inland and changed gradually from May through to April and from March to February, then moved towards the centre Dry Polygon area. Then it changed gradually from February to January and ended up in December, and moved further southwards. The annual cycle amplitude varied from <0.075 in northwest and southeast regions to >0.25 in the northeast region. By using spatial variations of phase, amplitude and mean NDVI values, 15 climate types were delineated for the NEB.The spatial distribution of climate types in the NEB delineated by the NDVI FFT analysis agreed mostly with the climatic types presented by Hargreaves (Precipitation dependability and potentials for agricultural production in Northeast Brazil. Empresa Brasileira de Pesquisa Agropecuária-EMBRAPA, Brazil, 1974), except regions with higher spatial variability and limited surface meteorological data. Among the three components: phase, amplitude and mean NDVI, the phase image, informing the initiation and duration of rainy season, was the most important component for climate-type delineation. Nevertheless, while the extreme values of amplitude, inferring a high wet

    2014-01-01

    Background The production and commercial release of Genetically Modified Organisms (GMOs) are currently the focus of important discussions. In order to guarantee the quality and reliability of their trials, companies and institutions working on this subject must adopt new approaches on management, organization and recording of laboratory conditions where field studies are performed. Computational systems for management and storage of laboratory data known as Laboratory Information Management Systems (LIMS) are essential tools to achieve this. Results In this work, we have used the SIGLa system – a workflow based LIMS as a framework to develop the FluxTransgenics system for a GMOs laboratory of Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Maize and Sorghum (Sete Lagoas, MG - Brazil). A workflow representing all stages of the transgenic maize plants generation has been developed and uploaded in FluxTransgenics. This workflow models the activities involved in maize and sorghum transformation using the Agrobacterium tumefaciens method. By uploading this workflow in the SIGLa system we have created Fluxtransgenics, a complete LIMS for managing plant transformation data. Conclusions FluxTransgenics presents a solution for the management of the data produced by a laboratory of genetically modified plants that is efficient and supports different kinds of information. Its adoption will contribute to guarantee the quality of activities and products in the process of transgenic production and enforce the use of Good Laboratory Practices (GLP). The adoption of the transformation protocol associated to the use of FluxTransgenics has made it possible to increase productivity by at least 300%, increasing the efficiency of the experiments from between 0.5 and 1 percent to about 3%. This has been achieved by an increase in the number of experiments performed and a more accurate choice of parameters, all of which have been made possible because it became easier to

In this paper we propose to show some of the experiences and didactic innovations in the teaching of geology found in the scientific literature in recent years and likewise part of an author's own work on the establishment of analogies on the time variable based on Carl Sagan's cosmic calendar. With these analogies we try to approximate geologic times to the understanding of high school and first university courses students (Aguirre-Perez, C. 2008) REFERENCES ALIBERAS, J.

    El impacto de la variabilidad y cambio climáticos, afectan el potencial agrícola de la Región Sur de Tamaulipas. Además de los cambios estacionales, bajos rendimientos agrícolas, el manejo de los cultivos y las políticas locales de producción, existe la incertidumbre del mercado regional para los pequeños y grandes productores. La diversificación agrícola ha sido una alternativa para enfrentar las condiciones imperantes en esta región. Pero ésta ha provocado la fragmentación territorial, por lo que sólo algunos productores logran competir en un mercado nacional. Existe una preocupación generalizada por buscar soluciones que permitan que la población que es afectada por la inseguridad de la producción agrícola y económica, pueda adaptarse a las variaciones climáticas que afectan el proceso productivo. La seguridad alimentaría queda sujeta a la fluctuación de las importaciones para los sectores básicos y a las estrategias mercantiles de empresas trasnacionales. La percepción local sugiere un número creciente de eventos climatológicos extremos, constantes y severos en los últimos 20 años, con el aumento creciente de pérdidas económicas. El análisis se centra en la disponibilidad de agua, agregándose un aspecto de capital importancia como es la variabilidad interanual de la lluvia, que condiciona muy fuertemente el riesgo agrícola en el trópico seco, siendo ésta la que determina el momento de inicio de la estación favorable para el crecimiento y su duración. En este trabajo se han obtenido modelos de la distribución espacial de la precipitación y temperaturas, para el escenario base 1961-1990, el escenario actual 1971-2000, para algunos años El Niño y La Niña, así como para los escenarios de Cambio Climático HADLEY, ECHAM y GFDL, con escenarios A2 y B2, para las décadas de los 20s y 50s, para establecer el inicio y duración de la Estación de Crecimiento, utilizando Sistemas de Información Geográfica (ArcView).

    Cada vez mais a humanidade, em sua imensa maioria, está alheia às próprias conquistas. A insatisfação com esta realidade tem levado muitos pesquisadores, instituições, empresas e governos a procurar formas alternativas de acompanhar e transmitir todo este acervo científico cultural à sociedade, buscando a melhoria da qualidade da divulgação científica e contribuindo para o processo de cultura e alfabetização científica. Não há tempo nem espaço nos limitados planos curriculares do ensino médio e mesmo nos programas de ensino que propiciem a cultura científica e o acompanhamento do vertiginoso progresso científico e tecnológico atual. Neste sentido, a educação formal escolar precisa ser complementada ou acrescida de uma educação informal, extra-escolar, que possa oferecer à sociedade o que a escola não pode oferecer. A interação do público com museus, feiras de ciências, planetários, exposições científicas e/ou culturais é de grande importância para a aquisição e difusão de conhecimentos relacionados ao mundo científico. Reconhecidamente como um modelo de alfabetização científica esses ambientes promovem uma interação social capaz de propiciar de forma efetiva uma melhor relação ensino-aprendizagem com o público. Partindo desta realidade a Universidade Cruzeiro do Sul e a Escola Municipal de Astronomia (EMA) vêm desenvolvendo um projeto de intervenção no espaço em torno do Planetário do Parque do Ibirapuera com o objetivo de se implantar um ambiente de aprendizagem motivador e desafiador que promova a popularização de conteúdos relacionados à astronomia, astrofísica e cosmologia. Busca-se, também, a aproximação e interação do público com exposições que estão sendo implementadas no planetário. Considerando que se trata de um projeto de mestrado em fase inicial o objetivo do presente trabalho é apresentar a concepção básica e os critérios que estão sendo utilizados do ponto de vista pedag

    centres de santé et les établissements gouvernementaux étaient les moins susceptibles de changer de traitement. Conclusions Les taux d’échecs immunologiques du traitement et les besoins non satisfaits pour le traitement de 2nde ligne sont élevés en Tanzanie. La surveillance virologique, au moins pour les personnes avec un échec immunologique de traitement, est nécessaire pour minimiser les passages inutiles au traitement de 2nde ligne. Les établissements de santé gouvernementaux de niveau inférieur ont besoin de plus de support pour réduire les taux d’échec de traitement et pour améliorer l'adoption de la thérapie de 2nde ligne afin de maintenir les avantages d'une couverture accrue. Objetivos Las tasas de fallo de la terapia de primera línea y los cambios a la terapia de segunda línea son indicadores claves para los programas nacionales de VIH. Hemos evaluado los fallos en el tratamiento inmunológico definidos según criterios de la OMS dentro del programa nacional para VIH en Tanzania. Métodos Hemos incluido adultos que iniciaban la terapia de primera línea entre el 2004-2011 con un conteo de CD4 antes de recibir el tratamiento, y tras ≥6 meses de seguimiento. Hemos evaluado los subíndices de riesgo del fallo inmunológico en el tratamiento, y el cambio subsecuente a la segunda línea de tratamiento, utilizando análisis de riesgo competitivo para explicar las muertes. Resultados De 121,308 adultos, un 7% experimentó fallo inmunológico, y un 2% murió sin observarse un fallo inmunológico en el tratamiento, a lo largo de una mediana de 1.7 años. La probabilidad acumulada a lo largo de seis años de fallo terapéutico inmunológico era del 19.0% (IC 95% 18.5, 19.7) y de muerte del 5.1% (4.8,5.4). Los vaticinadores de fallo terapéutico inmunológico incluían haber empezado el tratamiento un año antes (p<0.001), haberlo iniciado en centros de menor nivel (SHR=2.23 [2.03,2.45] para dispensarios versus hospitales), ser ombre (1.27 [1

    enfocan más en los conductores del comportamiento humano y en las implicaciones de varias fuentes de incertidumbre en la toma de decisiones de manejo. La cacería de trofeos ha sido sugerida como una herramienta de conservación porque le otorga valor económico a la vida silvestre, pero ejemplos recientes muestran que la sobrecolecta es un problema sustancial y que las limitaciones de datos son abundantes. Usamos el estudio de caso de la cacería de trofeos de un antílope en peligro, el nyala de las montañas (Tragelaphus buxtoni), para explorar como las incertidumbres generadas por el monitoreo de poblaciones y el tráfico de especies interactúan con la toma de decisiones de 2 actores clave: las compañías de safari y el gobierno. Construimos un modelo de evaluación de estrategia de manejo que incluye la dinámica poblacional del nyala de las montañas, un modelo de monitoreo y un modelo de toma de decisiones de una compañía. Investigamos escenarios de inversión en el combate del tráfico de especies y el monitoreo por el gobierno y las compañías de safari. La estrategia de colecta fue robusta hacia la incertidumbre en los estimados de población obtenidos del monitoreo, pero el tráfico de especies tuvo un efecto más fuerte sobre la cuota y la sustentabilidad; por esto, reducir el tráfico de especies está dentro de los intereses de compañías que desean incrementar la rentabilidad de las empresas, por ejemplo al hacer participar a los miembros de la comunidad como guías de caza. Hay un nivel umbral de incertidumbre en los estimados de población más allá del cual la variación anual en la cuota de trofeos previene la planeación por parte de las compañías de safari. Esto sugiere un papel para el gobierno asegurando que un nivel base de monitoreo de población se lleve a cabo para que este nivel no sea excedido. Nuestros resultados ilustran la importancia de considerar los incentivos de partes interes

    íficamente en el desequilibrio entre trabajo-vida. Una área de investigación que ha sido ignorada por mucho tiempo es la influencia potencial de las variables demográficas sobre la relación entre adicción al trabajo y el desequilibrio trabajo-vida. Por este motivo es que el presente estudio se focalizó en como el origen cultural puede influenciar la intensidad de esta relación. Tomando como base la teoría de la deprivación relativa y estudios empíricos previos, se esperó que el origen cultural moderaría la relación entre adicción al trabajo y desequilibrio trabajo-vida. Específicamente se pudo predecir que los participantes caucásicos mostraron más elevados puntajes en los niveles de adicción al trabajo que los participantes negros, y que la relación entre adicción al trabajo y desequilibrio trabajo-vida era más intensa entre los caucásicos que entre los negros. Los resultados revelaron que elevados niveles de adicción al trabajo correlacionaron significativamente con altos niveles de desequilibrio trabajo-vida. Sin embargo los resultados también revelaron que el origen cultural no moderaba la relación entre adicción al trabajo y desequilibrio trabajo-vida, y que además no había una diferencia significativa de medias entre los participantes caucásicos y negros respecto de nuestras mediciones de adicción al trabajo. Estos resultados son importantes en la medida en que es esencial para los empleadores el ser conscientes respecto de las tendencias de adicción al trabajo, lo que les permitirá manejar con mayor efectividad las consequencias negativas para la empresa resultantes de estas tendencias, y por otro lado apoyar a sus empleados en la promoción de su bienestar. Au cours des dernières années, le travaillolisme (workaholism) a pris de l'ampleur dans les organisations et a capté l'attention à la fois des dirigeants d'organisations et des communautés académique et scientifique.

    traditionally been aimed mainly at theorists, PASCOS2010 had a stronger emphasis on new results and future experiments. The venue for PASCOS 2010 was the Fundación Universidad Empresa (ADEIT), a modern building, located in the historical city centre of Valencia and very close to the conference hotels and to most historic buildings and monuments. The scientific programme consisted of 26 invited Plenary Talks and 99 contributions, all available online at http://pascos2010.astroparticles.es/. Young researchers were encouraged to submit abstracts, many of which were subsequently selected by the organizing committee for oral presentation in parallel sessions. This year's symposium, attended by over 160 participants from all over the globe, was of particular significance, as it came in the wake of first data from the LHC as well as the Planck satellite. In general, plenary sessions were held in the mornings, with afternoons devoted to parallel sessions focussing on the three areas of particles, strings and cosmology. Official Inauguration and Public Talk The Opening of the Symposium took place in the main Auditorium of ADEIT, starting with a brief welcome address by Professor José W F Valle, Chair of the Organizing Committee, followed by addresses of Professor Pedro Carrasco, Research Vice-Rector of the University of València, Professor José Pío Beltran, representing the President of the CSIC, and Professor Francisco Botella, Director of IFIC. There was also a very successful popular science talk by Professor Carlos Frenk, Director of the Institute for Computational Cosmology at Durham University in the United Kingdom on 'The Structure of the Universe'. This as well as the opening of the PASCOS2010 conference was covered by the local media, and a short summary is also published in the CERN Courier.

The venue for PASCOS 2010 was the Fundación Universidad Empresa (ADEIT), a modern building, located in the historical city centre of Valencia and very close to the conference hotels and to most historic buildings and monuments. The scientific programme consisted of 26 invited Plenary Talks and 99 contributions, all available online at http://pascos2010.astroparticles.es/. Young researchers were encouraged to submit abstracts, many of which were subsequently selected by the organizing committee for oral presentation in parallel sessions. This year's symposium, attended by over 160 participants from all over the globe, was of particular significance, as it came in the wake of first data from the LHC as well as the Planck satellite. In general, plenary sessions were held in the mornings, with afternoons devoted to parallel sessions focussing on the three areas of particles, strings and cosmology. Official Inauguration and Public Talk The Opening of the Symposium took place in the main Auditorium of ADEIT, starting with a brief welcome address by Professor José W F Valle, Chair of the Organizing Committee, followed by addresses of Professor Pedro Carrasco, Research Vice-Rector of the University of València, Professor José Pío Beltran, representing the President of the CSIC, and Professor Francisco Botella, Director of IFIC. There was also a very successful popular science talk by Professor Carlos Frenk, Director of the Institute for Computational Cosmology at Durham University in the United Kingdom on 'The Structure of the Universe'. This as well as the opening of the PASCOS2010 conference was covered by the local media, and a short summary is also published in the CERN Courier.

    radicular, deve estar exposta ao fósforo para suprir as necessidades das plantas. Ademais, há um determinado valor de concentração de fósforo, na solução do solo, acima da qual a taxa de absorção não é aumentada. Essas considerações suscitam a possibilidade de questionar se a aplicação de fósforo em sulcos seria a forma mais eficiente de usá-lo quando se pretende alcancar elevadas produções. Deve-se lembrar entretanto, que solos tropicais, ainda com baixos teores fósforo e alta capacidade de adsorção, seria necessária dose muito elevada de P, quando aplicada á lanço, em todo o terreno. Se a aplicação localizada do fósforo pode, em parte, ser explicada, a do nitrogênio e potássio não são facilmente justificadas sob o aspecto de eficiéncia de utilização. Pelo contrário, ela pode ser questionada, principalmente pelas suas caracteristicas de difusão, pelo efeito que altas concentração de amónio e cloreto podem ter sobre a pressão osmotica da solução do solo junto aos tubérculos plantados, pelo efeito negativo do cloreto sobre a absorção de fósforo e também sobre a capacidade produtiva das plantas. Portanto, existe a possibilidade de ocorrer toxidez de amónio e de cloreto ao se aplicar doses altas dos fertilizantes nos sulcos de plantios. Isto pode determinar uma menor eficiéncia no uso dos fertilizantes.
