    As a part of the US Department of Energy's Advanced Vehicle Testing Activity (AVTA), a model year 2010 Honda Insight was procured by eTec (Phoenix, AZ) and sent to ANL's Advanced Powertrain Research Facility for the purposes of vehicle-level testing in support of the Advanced Vehicle Testing Activity (AVTA). Data was acquired during testing using non-intrusive sensors, vehicle network information, and facilities equipment (emissions and dynamometer data). Standard drive cycles, performance cycles, steady-state cycles and A/C usage cycles were tested. Much of this data is openly available for download in ANL's Downloadable Dynamometer Database (D3). The major results are shown here in this report. Given the preliminary nature of this assessment, the majority of the testing was done over standard regulatory cycles and seeks to obtain a general overview of how the vehicle performs. These cycles include the US FTP cycle (Urban) and Highway Fuel Economy Test cycle as well as the US06, a more aggressive supplemental regulatory cycle. Data collection for this testing was kept at a fairly high level and includes emissions and fuel measurements from an exhaust emissions bench, high-voltage and accessory current and voltage from a DC power analyzer, and CAN bus data such as engine speed, engine load, and electric machine operation when available. The following sections will seek to explain some of the basic operating characteristics of the MY2010 Insight and provide insight into unique features of its operation and design.

    Honda has been doing research on robotics since 1986 with a focus upon bipedal walking technology. The research started with straight and static walking of the first prototype two-legged robot. Now, the continuous transition from walking in a straight line to making a turn has been achieved with the latest humanoid robot ASIMO. ASIMO is the most advanced robot of Honda so far in the mechanism and the control system. ASIMO's configuration allows it to operate freely in the human living space. It could be of practical help to humans with its ability of five-finger arms as well as its walking function. The target of further development of ASIMO is to develop a robot to improve life in human society. Much development work will be continued both mechanically and electronically, staying true to Honda's 'challenging spirit'.

    To avoid tipping over either during walking or on standing up, humans will first push down hard on the ground with a part of the sole of the foot. Then, when the tipping force can no longer be resisted, a change in body position or an extra step (stepping out) may be required to stabilise the posture. Our biped robot's control system attempts to reproduce and execute the same postural control operations carried out by humans. In this article, we present the history of robot development at Honda, fundamental dynamics for robots and the principles of posture control.

    Full Text Available La quebrada Honda, situada en el sur de la cuenca de los lagos La Plata y Fontana, en la provincia de Chubut, presenta una columna estratigráfica que comienza en el Jurásico superior con rocas calcoalcalinas de arco volcánico intermedias a ácidas de la Formación Lago La Plata. Las rocas sedimentarias que rellenan la cuenca de intraarco neocomiana corresponden al Grupo Coyhaique, dentro del cual se encuentran las Formaciones Tres Lagunas y Katterfeld, que se ubican dentro de un modelo paleoambiental como cortejo sedimentario de borde de plataforma, sucedido por un cortejo transgresivo, cuya edad es acotada al Hauteriviano inferior, debido al hallazgo de restos de Favrella americana en pelitas de la Formación Katterfeld. Vinculados con la extensión que da lugar a la cuenca se registran los cuerpos hipabisales calcoalcalinos básicos del Gabro Quebrada Honda y se los relaciona con un volcanismo de características más evolucionadas de la Formación Don Rueda, de edad neocomiana tardía. Si bien este magmatismo de arco volcánico es subaéreo, presenta indicios de interacción con cuerpos de agua por lo que corrobora la concomitancia de este evento con la sedimentación póstuma de Grupo Coyhaique. Se registra un evento de inversión tectónica que tendría una edad máxima de 80 Ma.The quebrada Honda is situated in the Lago La Plata-Fontana basin in Chubut. The stratigraphy of the area begins in the Upper Jurassic with the calc-alkaline intermediate to acidic Lago La Plata Formation rocks.

    From 1975 until 2006,18 intense storms triggered at least 248 debris flows within 10 km2 northwest of the town of La Honda within the Santa Cruz Mountains, California. In addition to mapping debris flows and other types of landslides, studies included soil sampling and geologic mapping, piezometric and tensiometer monitoring, and rainfall measurement and recording. From 1985 until 1995, a system with radio telemetered rain gages and piezometers within the La Honda region was used for issuing six debris-flow warnings within the San Francisco Bay region through the NOAA ALERT system. Depending upon the relative intensity of rainfall during storms, debris flows were generated from deep slumps, shallow slumps, shallow slides in colluvium and shallow slides over bedrock. Analysis shows the storms with abundant antecedent rainfall followed by several days of steady heavy intense rainfall triggered the most abundant debris flows. ?? 2007 millpress.

    The UltraBattery Retrofit Project DP1.8 and Carbon Enriched Project C3, performed by ECOtality North America (ECOtality) and funded by the U.S. Department of Energy and the Advanced Lead Acid Battery Consortium (ALABC), are established to demonstrate the suitability of advanced lead battery technology in hybrid electrical vehicles (HEVs). A profile, termed the “Simulated Honda Civic HEV Profile” (SHCHEVP) has been developed in Project DP1.8 in order to provide reproducible laboratory evaluations of different battery types under real-world HEV conditions. The cycle is based on the Urban Dynamometer Driving Schedule and Highway Fuel Economy Test cycles and simulates operation of a battery pack in a Honda Civic HEV. One pass through the SHCHEVP takes 2,140 seconds and simulates 17.7 miles of driving. A complete nickel metal hydride (NiMH) battery pack was removed from a Honda Civic HEV and operated under SHCHEVP to validate the profile. The voltage behavior and energy balance of the battery during this operation was virtually the same as that displayed by the battery when in the Honda Civic operating on the dynamometer under the Urban Dynamometer Driving Schedule and Highway Fuel Economy Test cycles, thus confirming the efficacy of the simulated profile. An important objective of the project has been to benchmark the performance of the UltraBatteries manufactured by both Furukawa Battery Co., Ltd., Japan (Furakawa) and East Penn Manufacturing Co., Inc. (East Penn). Accordingly, UltraBattery packs from both Furakawa and East Penn have been characterized under a range of conditions. Resistance measurements and capacity tests at various rates show that both battery types are very similar in performance. Both technologies, as well as a standard lead-acid module (included for baseline data), were evaluated under a simple HEV screening test. Both Furakawa and East Penn UltraBattery packs operated for over 32,000 HEV cycles, with minimal loss in performance; whereas the

    Aranda-Gómez, JoséJorge; Luhr, James F.

    1996-11-01

    Joya Honda is a Quaternary maar of unusual type from the Mexican Basin and Range Province. Its ~ 300-m-deep crater is excavated in Cretaceous limestones. The surrounding tephra deposit, which in places is > 100 m thick, begins with a series of weakly indurated pyroclastic-surge and -fall layers that we interpret as dry-surge deposits. These are overlain by the main sequence of strongly indurated, massive tuff breccias that we interpret as wet-surge deposits. Joya Honda formed subaerially from the interaction of groundwater with rapidly ascending intraplate-type basanitic magma carrying peridotitic mantle xenoliths. Local aquifer characteristics controlled the style of eruption and the nature of the deposits. Groundwater in the limestone-hosted aquifer beneath Joya Honda was apparently contained within solution-enhanced fractures. At the onset of the eruption, magma began to interact with a moderate amount of groundwater, producing the dry-surge deposits, which are typical of deposits found at many maars and tuff rings. As the eruption continued, the crater grew and the hydromagmatic blasts fractured the limestones around the explosion foci. A marked increase in the water/magma ratio of the system followed when a large fracture or a portion of the limestone with enhanced secondary permeability was intersected by the expanding crater. Subsequent phreatomagmatic explosions occurred in a system with groundwater flow rates several orders of magnitude larger than in the initial dry-surge stage. At the maar rim these wet eruptions led to the emplacement of massive tuff breccias through a combination of fallout, surges and mudflows. These steeply dipping tuff breccias are similar to deposits found at many tuff cones. Juvenile clasts in the near-vent deposits show marked upward increases in both hydration (palagonitization) and vesicularity. The increased palagonitization with height in the section appears to be a consequence of the overall increased wetness of the eruption

  5. Geophysical surveys of the Joya Honda maar (México) and surroundings; volcanic implications

    Science.gov (United States)

    López Loera, Héctor; Aranda-Gómez, José Jorge; Arzate, Jorge A.; Molina-Garza, Roberto Stanley

    2008-03-01

    Joya Honda (JH) is a Quaternary maar excavated in Mesozoic limestone. It is located in central Mexico and belongs to the Ventura volcanic field (VVF), which is composed by cinder cones and maars made of intraplate-type mafic alkalic rocks. Volcanoes in the region form ˜ N20W lineaments, roughly parallel to a regional set of normal faults, but there is no obvious relation between these faults and vent distribution in the exposed geology around the maar. The volcanic rock volume is small in the VVF, and most volcanoes and their products are scattered in a region where outcrops are dominated by limestone. The near-vent tephra associated to the JH maar lies north of the crater. This relation suggests that the crater was formed by directed hydromagmatic explosions and may indicate an inclined volcanic conduit near the surface. The tephra stratigraphy suggests that the initial explosions were relatively dry and the amount of water increased during the maar forming eruption. Therefore, the existing model of the maar-diatreme formation may not be applicable to Joya Honda as it requires the formation of a cone of depression in the aquifer and deepening of the focii of the explosions as the crater and underlying diatreme grew. Thus, it is unlikely that there is a diatreme below Joya Honda. Aeromagnetic data shows a boundary between two regional magnetic domains near the elongated volcanic cluster of the VVF. The boundary is straight, with a distinct kink, from NE- to NW-trend, near JH. The limit between the domains is interpreted as fault contacts between mid-Tertiary volcanic rocks and marine Mesozoic sedimentary rocks. Hence, magma ascent in the area may have been facilitated by fractures near the surface. Magnetic and gravimetric ground surveys show that the anomalies associated with the maar are not centered in the crater, which could be consistent with an inclined volcanic conduit. A magnetic profile measured on exposed limestone across the volcanic lineament failed to

    Full Text Available La quebrada Honda, situada en el sur de la cuenca de los lagos La Plata y Fontana, en la provincia de Chubut, presenta una columna estratigráfica que comienza en el Jurásico superior con rocas calcoalcalinas de arco volcánico intermedias a ácidas de la Formación Lago La Plata. Las rocas sedimentarias que rellenan la cuenca de intraarco neocomiana corresponden al Grupo Coyhaique, dentro del cual se encuentran las Formaciones Tres Lagunas y Katterfeld, que se ubican dentro de un modelo paleoambiental como cortejo sedimentario de borde de plataforma, sucedido por un cortejo transgresivo, cuya edad es acotada al Hauteriviano inferior, debido al hallazgo de restos de Favrella americana en pelitas de la Formación Katterfeld. Vinculados con la extensión que da lugar a la cuenca se registran los cuerpos hipabisales calcoalcalinos básicos del Gabro Quebrada Honda y se los relaciona con un volcanismo de características más evolucionadas de la Formación Don Rueda, de edad neocomiana tardía. Si bien este magmatismo de arco volcánico es subaéreo, presenta indicios de interacción con cuerpos de agua por lo que corrobora la concomitancia de este evento con la sedimentación póstuma de Grupo Coyhaique. Se registra un evento de inversión tectónica que tendría una edad máxima de 80 Ma.

    This paper describes a novel species of ericoid mycorrhizal fungus from Australia, Cairneyella variabilis, Midgley and Tran-Dinh, gen. nov. sp. nov. The genome of C. variabilis was sequenced and a draft genome assembled. The draft genome of C. variabilis is 52.4 Mbp in length, and to our knowledge, this is the first study to present a genome of an ericoid mycorrhizal fungus from the southern hemisphere. Using the SignalP and dbCAN bioinformatic pipelines, a study of the catabolic potential of C. variabilis was undertaken and showed genes for an array of degradative enzymes, most of which appear to be secreted from the hyphae, to access a suite of different carbon sources. Isolates of C. variabilis have been previously shown to utilise cellulose, carboxymethyl cellulose (CMC), cellobiose, xylan, pectin, starch and tannic acid for growth, and in the current study, putative enzymes for these processes were revealed. These enzymes likely play key roles in nutrient cycling and other edaphic processes in heathland environments. ITS phylogenetic analyses showed C. variabilis to be distinct from the fungi of the "Hymenoscyphus ericae aggregate".

    2013-08-01

    Honda has developed a 3rd-generation diesel engine, seeking to balance further CO{sub 2} reductions with dynamic performance. This development focused on downsizing the engine and succeeded in developing a compact, lightweight and high-efficiency 1.6 L in-line 4-cylinder turbocharged i-DTEC diesel engine. Optimization of engine rigidity in the newly developed 1.6 L diesel engine has made it possible to use an aluminum cylinder block with an open-deck structure. Furthermore, weight could be reduced by means of an efficient structure and engine layout. In addition, mechanical friction has been minimized via reducing weight of the reciprocating components and downsizing auxiliary equipment. These innovations made it possible for the engine to achieve the same level of friction as a Honda petrol engine of the same displacement. Thermal management has also been optimized by enhancement of the engine cooling system. In addition, low-pressure loop exhaust gas recirculation (LP-EGR) was applied to achieve increased thermal efficiency. These measures have helped the engine to realize a high level of boost and high EGR, increasing fuel efficiency and reducing emissions across a wide range of operating conditions. Like the 2.2 L model, the Civic fitted with this 1.6 L diesel engine uses idle-stop and deceleration energy regeneration control. With all these measures, the Civic achieved CO{sub 2} emissions of 94 g/km (3.6 L/100km) in NEDC, a reduction of 14.5% in CO{sub 2} emissions against the 110 g/km recorded by the 2.2 L model.

  8. A novel role of human holliday junction resolvase GEN1 in the maintenance of centrosome integrity.

    Directory of Open Access Journals (Sweden)

    Min Gao

    Full Text Available The maintenance of genomic stability requires accurate genome replication, repair of DNA damage, and the precise segregation of chromosomes in mitosis. GEN1 possesses Holliday junction resolvase activity in vitro and presumably functions in homology driven repair of DNA double strand breaks. However, little is currently known about the cellular functions of human GEN1. In the present study we demonstrate that GEN1 is a novel centrosome associated protein and we characterize the various phenotypes associated with GEN1 deficiency. We identify an N-terminal centrosome localization signal in GEN1, which is required and sufficient for centrosome localization. We report that GEN1 depletion results in aberrant centrosome numbers associated with the formation of multiple spindle poles in mitosis, an increased number of cells with multi-nuclei, increased apoptosis and an elevated level of spontaneous DNA damage. We find homologous recombination severely impaired in GEN1 deficient cells, suggesting that GEN1 functions as a Holliday junction resolvase in vivo as well as in vitro. Complementation of GEN1 depleted cells with various GEN1 constructs revealed that centrosome association but not catalytic activity of GEN1 is required for preventing centrosome hyper-amplification, formation of multiple mitotic spindles, and multi-nucleation. Our findings provide novel insight into the biological functions of GEN1 by uncovering an important role of GEN1 in the regulation of centrosome integrity.

    Full Text Available Emplazada en la zona de transición sur del segmento de flat-slab pampeano y directamente vinculada a la horizontalización de la placa de Nazca, la faja volcánica terciaria de San Luis delata la migración que experimentó el arco magmático andino a la latitud de los 33º S en tiempos mio-pliocenos. Esta faja volcánica comprende una serie de distritos metalogenéticos de gran importancia en las Sierras Pampeanas de San Luis. Las rocas volcánicas y mineralizaciones de la faja volcánica terciaria se encuentran representadas en los campos volcánicos La Carolina, Cañada Honda - Cerros Largos, Cerros del Rosario y El Morro, dispuestos saltuariamente según una dirección ONO-NO. Las edades K-Ar disponibles indican que el volcanismo se habría iniciado más tempranamente en el sector occidental de esta faja, y que habría finalizado ~ 10 Ma más tarde en la región oriental. El distrito Cañada Honda, el más antiguo y longevo de esta faja volcánica, registra eventos volcánicos e hidrotermales cuyas edades varían entre 12-13 Ma y 7,3 Ma, abarcando facies lávico-hipabisales y volcaniclásticas. Los resultados del análisis estructural demuestran el importante control que, directa o indirectamente, habrían ejercido las estructuras previas en el emplazamiento de las rocas volcánicas y mineralizaciones. Análisis de fábrica deformacional y cinemático han permitido reconocer dos asociaciones volcano-tectónicas diferentes. una de estas asociaciones se vincularía a la reactivación dextral de estructuras paralelas a la foliación del basamento. La asociación principal estaría vinculada con el desarrollo de dos depresiones volcano-tectónicas alineadas en dirección ONO-NO. Sus estructuras principales, de orientación ONO-NO, revelan componentes de desplazamiento senestral y normal tanto a escala del distrito Cañada Honda como de la faja volcánica terciaria.

  15. Giant fossil tortoise and freshwater chelid turtle remains from the middle Miocene, Quebrada Honda, Bolivia: Evidence for lower paleoelevations for the southern Altiplano

    Science.gov (United States)

    Cadena, Edwin A.; Anaya, Federico; Croft, Darin A.

    2015-12-01

    We describe the first Miocene turtle remains from Bolivia, which were collected from the late middle Miocene (13.18-13.03 Ma) of Quebrada Honda, southern Bolivia. This material includes a large scapula-acromion and fragmentary shell elements conferred to the genus Chelonoidis (Testudinidae), and a left xiphiplastron from a pleurodire or side-necked turtle, conferred to Acanthochelys (Chelidae). The occurrence of a giant tortoise and a freshwater turtle suggests that the paleoelevation of the region when the fossils were deposited was lower than has been estimated by stable isotope proxies, with a maximum elevation probably less than 1000 m. At a greater elevation, cool temperatures would have been beyond the tolerable physiological limits for these turtles and other giant ectotherm reptiles.

    The Orion spacecraft is currently under development by NASA and Lockheed Martin. Like Apollo, Orion will use a series of parachutes to slow its descent and splashdown safely. The Orion parachute system, known as the CEV Parachute Assembly System (CPAS), is being designed by NASA, the Engineering and Science Contract Group (ESCG), and Airborne Systems. The first generation (Gen I) of CPAS testing consisted of thirteen tests and was executed in the 2007-2008 timeframe. The Gen I tests provided an initial understanding of the CPAS parachutes. Knowledge gained from Gen I testing was used to plan the second generation of testing (Gen II). Gen II consisted of six tests: three singleparachute tests, designated as Main Development Tests, and three Cluster Development Tests. Gen II required a more thorough investigation into parachute performance than Gen I. Higher fidelity instrumentation, enhanced analysis methods and tools, and advanced test techniques were developed. The results of the Gen II test series are being incorporated into the CPAS design. Further testing and refinement of the design and model of parachute performance will occur during the upcoming third generation of testing (Gen III). This paper will provide an overview of the developments in CPAS analysis following the end of Gen I, including descriptions of new tools and techniques as well as overviews of the Gen II tests.

    Holliday junctions (HJs) are key DNA intermediates in homologous recombination. They link homologous DNA strands and have to be faithfully removed for proper DNA segregation and genome integrity. Here, we present the crystal structure of human HJ resolvase GEN1 complexed with DNA at 3.0 Å resolution. The GEN1 core is similar to other Rad2/XPG nucleases. However, unlike other members of the superfamily, GEN1 contains a chromodomain as an additional DNA interaction site. Chromodomains are known for their chromatin-targeting function in chromatin remodelers and histone(de)acetylases but they have not previously been found in nucleases. The GEN1 chromodomain directly contacts DNA and its truncation severely hampers GEN1's catalytic activity. Structure-guided mutations in vitro and in vivo in yeast validated our mechanistic findings. Our study provides the missing structure in the Rad2/XPG family and insights how a well-conserved nuclease core acquires versatility in recognizing diverse substrates for DNA repair and maintenance.

    Members of genus Peptostreptococcus have previously been found to be distantly related to the type species, Peptostreptococcus anaerobius, on the basis of 16S rDNA sequence similarities. They were divided into three major phylogenetic groups, and their peptidoglycan structure and biochemical traits differed between groups. The reclassification of the species of these three groups into three new genera, Peptoniphilus gen. nov., Anaerococcus gen. nov. and Gallicola gen. nov., is proposed. The genus Peptoniphilus gen. nov. includes the following butyrate-producing, non-saccharolytic species that use peptone and amino acids as major energy sources: Peptoniphilus asaccharolyticus comb. nov. (type species), Peptoniphilus lacrimaris comb. nov., Peptoniphilus harei comb. nov., Peptoniphilus indolicus comb. nov. and Peptoniphilus ivorii comb. nov. The genus Anaerococcus gen. nov. contains the saccharolytic, butyrate-producing species Anaerococcus prevotii comb. nov. (type species), Anaerococcus tetradius comb. nov., Anaerococcus lactolyticus comb. nov., Anaerococcus hydrogenalis comb. nov., Anaerococcus vaginalis comb. nov. and Anaerococcus octavius sp. nov. The genus Gallicola gen. nov. contains a single species, Gallicola barnesae comb. nov.

  12. Unleashing Gen Y: Marketing Mars to Millennials

    Leahy, Bart D.; Hidalgo, Loretta; Kloberdanz, Cassie

    2007-01-01

    Space advocates need to engage Generation Y (born 1977-1999).This outreach is necessary to recruit the next generation of scientists and engineers to explore Mars. Space advocates in the non-profit, private, and government sectors need to use a combination of technical communication, marketing, and politics, to develop messages that resonate with Gen Y. Until now, space messages have been generated by and for college-educated white males; Gen Y is much more diverse, including as much as one third minorities. Young women, too, need to be reached. My research has shown that messages emphasizing technology, fun, humor, and opportunity are the best means of reaching the Gen Y audience of 60 million (US population is 300 million). The important things space advocates must avoid are talking down to this generation, making false promises, or expecting them to "wait their turn" before they can participate. This is the MTV generation! We need to find ways of engaging Gen Y now to build a future where human beings can live and work on the planet Mars. In addition to the messages themselves, advocates need to keep up with Gen Y' s social networking and use of iPods, cell phones, and the Internet. NASA and space advocacy groups can use these tools for "viral marketing," where young people share targeted space-related information via cell phones or the Internet because they like it. Overall, Gen Y is a socially dynamic and media-savvy group; advocates' space messages need to be sincere, creative, and placed in locations where Gen Y lives. Mars messages must be memorable!

  2. Simulating GenCo bidding strategies in electricity markets with an agent-based model

    Energy Technology Data Exchange (ETDEWEB)

    Botterud, Audun; Thimmapuram, Prakash R.; Yamakado, Malo

    2005-12-15

    In this paper we use an agent-based simulation model, EMCAS, to analyze market power in electricity markets. We focus on the effect of congestion management on the ability of generating companies (GenCos) to raise prices beyond competitive levels. An 11-node test power system is used to compare a market design based on locational marginal pricing with a market design that uses system marginal pricing and congestion management by counter trading. Bidding strategies based on both physical and economic withholding are compared to a base case with production cost bidding. The results show that unilateral market power is exercised under both pricing mechanisms. However, the largest changes in consumer costs and GenCo profits due to strategic bidding occur under the locational marginal pricing scheme. The analysis also illustrates that agent-based modeling can contribute important insights into the complex interactions between the participants in transmission-constrained electricity markets.

    2005-03-29

    A Gen IV Materials Handbook is being developed to provide an authoritative single source of highly qualified structural materials information and materials properties data for use in design and analyses of all Generation IV Reactor Systems. The Handbook will be responsive to the needs expressed by all of the principal government, national laboratory, and private company stakeholders of Gen IV Reactor Systems. The Gen IV Materials Handbook Implementation Plan provided here addresses the purpose, rationale, attributes, and benefits of the Handbook and will detail its content, format, quality assurance, applicability, and access. Structural materials, both metallic and ceramic, for all Gen IV reactor types currently supported by the Department of Energy (DOE) will be included in the Gen IV Materials Handbook. However, initial emphasis will be on materials for the Very High Temperature Reactor (VHTR). Descriptive information (e.g., chemical composition and applicable technical specifications and codes) will be provided for each material along with an extensive presentation of mechanical and physical property data including consideration of temperature, irradiation, environment, etc. effects on properties. Access to the Gen IV Materials Handbook will be internet-based with appropriate levels of control. Information and data in the Handbook will be configured to allow search by material classes, specific materials, specific information or property class, specific property, data parameters, and individual data points identified with materials parameters, test conditions, and data source. Details on all of these as well as proposed applicability and consideration of data quality classes are provided in the Implementation Plan. Website development for the Handbook is divided into six phases including (1) detailed product analysis and specification, (2) simulation and design, (3) implementation and testing, (4) product release, (5) project/product evaluation, and (6) product

    The generation of minimum operational, safety, performance, and interoperability requirements is an important aspect of safely integrating new NextGen components into the Communication Navigation Surveillance and Air Traffic Management (CNS/ATM) system. These requirements are used as part of the implementation and approval processes. In addition, they provide guidance to determine the levels of design assurance and performance that are needed for each element of the new NextGen procedures, including aircraft, operator, and Air Navigation and Service Provider. Using the enhanced Airborne Traffic Situational Awareness for InTrail Procedure (ATSA-ITP) as an example, this report describes some limitations of the current process used for generating safety requirements and levels of required design assurance. An alternative process is described, as well as the argument for why the alternative can generate more comprehensive requirements and greater safety assurance than the current approach.

    Full Text Available Los estudios sobre los procesos responsables del ensamblaje de las especies en comunidades ecológicas tradicionalmente han considerado a las especies como unidades de estudio. Sin embargo, dentro de las especies existe gran cantidad de variación genotípica y fenotípica que puede finalmente ser decisiva en el resultado de las interacciones con el resto de especies en la comunidad (competencia, mutualismo, etc. Recientemente se ha propuesto una nueva regla de ensamblaje de las comunidades que sugiere que la composición genética de una población afecta a la estructura y composición de la comunidad (es decir alfenotipo de la comunidad. Apoyando esta regla, varios estudios han demostrado que los cambios en la diversidad genética de poblaciones de plantas conllevan cambios predecibles en sus comunidades asociadas de herbívoros y predadores. Más allá de la visión poblacional, la nueva genética de comunidades pretende demostrar 1 que el genotipo particular de ciertos individuos es responsable del fenotipo de la comunidad, 2 que el fenotipo de la comunidad es heredable, y por lo tanto 3 que las comunidades evolucionan. Tras explicar estos tres conceptos, se discute el valor que esta aproximación puede tener desde el punto de vista de la biología de la conservación.

    Samaras, M.; Hoffelner, W.; Victoria, M.

    2007-09-01

    The choice of suitable materials and the assessment of long-term materials damage are key issues that need to be addressed for the safe and reliable performance of nuclear power plants. Operating conditions such as high temperatures, irradiation and a corrosive environment degrade materials properties, posing the risk of very expensive or even catastrophic plant damage. Materials scientists are faced with the scientific challenge to determine the long-term damage evolution of materials under service exposure in advanced plants. A higher confidence in life-time assessments of these materials requires an understanding of the related physical phenomena on a range of scales from the microscopic level of single defect damage effects all the way up to macroscopic effects. To overcome lengthy and expensive trial-and-error experiments, the multiscale modelling of materials behaviour is a promising tool, bringing new insights into the fundamental understanding of basic mechanisms. This paper presents the multiscale modelling methodology which is taking root internationally to address the issues of advanced structural materials for Gen IV reactors.

    ORPC Maine, LLC, a wholly-owned subsidiary of Ocean Renewable Power Company, LLC (collectively ORPC), submits this Final Technical Report for the TidGen® Power System Commercialization Project (Project), partially funded by the U.S. Department of Energy (DE-EE0003647). The Project was built and operated in compliance with the Federal Energy Regulatory Commission (FERC) pilot project license (P-12711) and other permits and approvals needed for the Project. This report documents the methodologies, activities and results of the various phases of the Project, including design, engineering, procurement, assembly, installation, operation, licensing, environmental monitoring, retrieval, maintenance and repair. The Project represents a significant achievement for the renewable energy portfolio of the U.S. in general, and for the U.S. marine hydrokinetic (MHK) industry in particular. The stated Project goal was to advance, demonstrate and accelerate deployment and commercialization of ORPC’s tidal-current based hydrokinetic power generation system, including the energy extraction and conversion technology, associated power electronics, and interconnection equipment capable of reliably delivering electricity to the domestic power grid. ORPC achieved this goal by designing, building and operating the TidGen® Power System in 2012 and becoming the first federally licensed hydrokinetic tidal energy project to deliver electricity to a power grid under a power purchase agreement in North America. Located in Cobscook Bay between Eastport and Lubec, Maine, the TidGen® Power System was connected to the Bangor Hydro Electric utility grid at an on-shore station in North Lubec on September 13, 2012. ORPC obtained a FERC pilot project license for the Project on February 12, 2012 and the first Maine Department of Environmental Protection General Permit issued for a tidal energy project on January 31, 2012. In addition, ORPC entered into a 20-year agreement with Bangor Hydro Electric

    Full Text Available O autismo é um transtorno fortemente genético, com uma herdabilidade estimada de mais de 90%. Uma combinação de heterogeneidade fenotípica e o provável envolvimento de múltiplos loci que interagem entre si dificultam os esforços de descobertas de genes. Conseqüentemente, a etiologia genética dos transtornos relacionados ao autismo permanece, em grande parte, desconhecida. Nos últimos anos, a convergência entre tecnologias genômicas em rápido avanço, a finalização do projeto genoma humano e os crescentes e exitosos esforços em colaboração para aumentar o número de pacientes disponíveis para estudo conduziram às primeiras pistas sólidas sobre as origens biológicas desses transtornos. Este artigo revisará a literatura até nossos dias, resumindo os resultados de estudos de ligação genética, citogenéticos e de genes candidatos com um foco no progresso recente. Além disso, são consideradas as vias promissoras para pesquisas futuras.Autism is a strongly genetic disorder, with an estimated heritability of greater than 90%. A combination of phenotypic heterogeneity and the likely involvement of multiple interacting loci have hampered efforts at gene discovery. As a consequence, the genetic etiology of the spectrum of autism related disorders remains largely unknown. Over the past several years, the convergence of rapidly advancing genomic technologies, the completion of the human genome project, and increasingly successful collaborative efforts to increase the number of patients available for study have led to the first solid clues to the biological origins of these disorders. This paper will review the literature to date summarizing the results of linkage, cytogenetic, and candidate gene studies with a focus on recent progress. In addition, promising avenues for future research are considered.

  18. Dual-track CCS stakeholder engagement: Lessons learned from FutureGen in Illinois

    Science.gov (United States)

    Hund, G.; Greenberg, S.E.

    2011-01-01

    FutureGen, as originally planned, was to be the world's first coal-fueled, near-zero emissions power plant with fully integrated, 90% carbon capture and storage (CCS). From conception through siting and design, it enjoyed strong support from multiple stakeholder groups, which benefited the overall project. Understanding the stakeholder engagement process for this project provides valuable insights into the design of stakeholder programs for future CCS projects. FutureGen is one of few projects worldwide that used open competition for siting both the power plant and storage reservoir. Most site proposals were coordinated by State governments. It was unique in this and other respects relative to the site selection method used on other DOE-supported projects. At the time of site selection, FutureGen was the largest proposed facility designed to combine an integrated gasification combined cycle (IGCC) coal-fueled power plant with a CCS system. Stakeholder engagement by states and the industry consortium responsible for siting, designing, building, and operating the facility took place simultaneously and on parallel tracks. On one track were states spearheading state-wide site assessments to identify candidate sites that they wanted to propose for consideration. On the other track was a public-private partnership between an industry consortium of thirteen coal companies and electric utilities that comprised the FutureGen Alliance (Alliance) and the U.S. Department of Energy (DOE). The partnership was based on a cooperative agreement signed by both parties, which assigned the lead for siting to the Alliance. This paper describes the stakeholder engagement strategies used on both of these tracks and provides examples from the engagement process using the Illinois semi-finalist sites. ?? 2011 Published by Elsevier Ltd.

    VaxGen is developing prophylactic vaccines against HIV-1 consisting of two recombinant gp120 surface proteins from different HIV-1 strains.This profile has been selected from R&D Insight, a pharmaceutical intelligence database produced by Adis International Ltd. The bivalent vaccines [AIDSVAX B/B and AIDSVAX B/E] are being evaluated in two phase III trials. The first multicentre phase III trial of AIDSVAX B/B, was conducted principally in Canada and the US but also at some sites in the Netherlands and Puerto Rico. The trial was completed at the end of 2002. The second phase III trial is being conducted in Thailand with the AIDSVAX B/E vaccine. VaxGen announced in July 2002 that it would be delaying its Biologics License Application (BLA) for AIDSVAX until 2004 to enable the company to fulfil pre-approval manufacturing requirements. AIDSVAX is based on an earlier monovalent gp120 vaccine developed by Genentech that was shown to be safe in humans. VaxGen (formerly Genenvax) was formed as a spin-off company from Genentech with the sole purpose of developing the gp120 vaccine. VaxGen announced in July 2002 that the original License and Supply agreement with Genentech, signed in May 1997, had been amended. Under the revised agreement, Genentech maintains its right to market and sell AIDSVAX in North America, but has relinquished its options to commercialise the vaccine candidate in the rest of the world. Genentech's earlier decision to waive its option to manufacture AIDSVAX has also been formalised in this agreement. Additionally, VaxGen's royalty payments to Genentech for sales to the WHO or UN for underdeveloped nations have also been reduced by up to 50% and Genentech has extended the milestone date associated with VaxGen submitting an NDA. A $US120 million joint venture (Celltrion) has been formed between VaxGen and South Korean investors to manufacture more than 200 million doses of AIDSVAX a year. Celltrion will build and operate two biotechnology manufacturing

    2011-01-01

    The successful implementation of the next generation infrastructure systems requires solid understanding of their technical, social, political and economic aspects along with their interactions. The lack of historical data that relate to the long-term planning of complex systems introduces unique challenges for decision makers and involved stakeholders which in turn result in unsustainable systems. Also, the need to understand the infrastructure at the societal level and capture the interaction between multiple stakeholders becomes important. This paper proposes a methodology in order to develop a holistic approach aiming to provide an alternative subject-matter expert (SME) elicitation and data collection method for future sociotechnical systems. The methodology is adapted to Next Generation Air Transportation System (NextGen) decision making environment in order to demonstrate the benefits of this holistic approach.

  14. RxGen General Optical Model Prescription Generator

    Sigrist, Norbert

    2012-01-01

    RxGen is a prescription generator for JPL's in-house optical modeling software package called MACOS (Modeling and Analysis for Controlled Optical Systems), which is an expert optical analysis software package focusing on modeling optics on dynamic structures, deformable optics, and controlled optics. The objectives of RxGen are to simplify and automate MACOS prescription generations, reducing errors associated with creating such optical prescriptions, and improving user efficiency without requiring MACOS proficiency. RxGen uses MATLAB (a high-level language and interactive environment developed by MathWorks) as the development and deployment platform, but RxGen can easily be ported to another optical modeling/analysis platform. Running RxGen within the modeling environment has the huge benefit that variations in optical models can be made an integral part of the modeling state. For instance, optical prescription parameters determined as external functional dependencies, optical variations by controlling the in-/exclusion of optical components like sub-systems, and/or controlling the state of all components. Combining the mentioned capabilities and flexibilities with RxGen's optical abstraction layer completely eliminates the hindering aspects for requiring proficiency in writing/editing MACOS prescriptions, allowing users to focus on the modeling aspects of optical systems, i.e., increasing productivity and efficiency. RxGen provides significant enhancements to MACOS and delivers a framework for fast prototyping as well as for developing very complex controlled optical systems.

Although J3Gen has been shown to fulfill the randomness criteria set by the EPCglobal Gen2 standard and is intended for security applications, we describe here two cryptanalytic attacks that question its security claims: (i a probabilistic attack based on solving linear equation systems; and (ii a deterministic attack based on the decimation of the output sequence. Numerical results, supported by simulations, show that for the specific recommended values of the configurable parameters, a low number of intercepted output bits are enough to break J3Gen. We then make some recommendations that address these issues.

    Jimtrappea guyanensis gen. sp. nov., Castellanea pakaraimophila gen. sp. nov., and Costatisporus cyanescens gen. sp. nov. are described as new to science. These sequestrate, hypogeous fungi were collected in Guyana under closed canopy tropical forests in association with ectomycorrhizal (ECM) host tree genera Dicymbe (Fabaceae subfam. Caesalpinioideae), Aldina (Fabaceae subfam. Papilionoideae), and Pakaraimaea (Dipterocarpaceae). Molecular data place these fungi in Boletaceae (Boletales, Agaricomycetes, Basidiomycota) and inform their relationships to other known epigeous and sequestrate taxa within that family. Macro- and micromorphological characters, habitat, and multi-locus DNA sequence data are provided for each new taxon. Unique morphological features and a molecular phylogenetic analysis of 185 taxa across the order Boletales justify the recognition of the three new genera.

    Two Cyanobacteria isolated from South Atlantic Ocean continental shelf deep water and from a marine green algae inhabiting the Admiralty Bay, King George Island, Antarctica were investigated based on morphological and ultrastructural traits, phylogeny of 16S rRNA gene sequences, secondary structure of the 16S-23S internal transcribed spacer regions and phylogenomic analyses. The majority of these evaluations demonstrated that both strains differ from the genera of cyanobacteria with validly published names and, therefore, supported the description of the novel genus as Aliterella gen. nov. The identity and phylogeny of 16S rRNA gene sequences, together with the secondary structure of D1D1' and BoxB intergenic regions, further supported the two strains representing distinct species: Aliterella atlantica gen. nov., sp. nov. (type SP469036, strain CENA595T) and Aliterella antarctica sp. nov. (type SP469035, strain CENA408T). The phylogenomic analysis of A. atlantica sp. nov. CENA595T, based on 21 protein sequences, revealed that this genus belongs to the cyanobacterial order Chroococcidiopsidales. The isolation and cultivation of two geographically distant unicellular members of a novel cyanobacterial genus and the sequenced genome of the type strain bring new insights into the current classification of the coccoid group, and into the reconstruction of their evolutionary history.

    Salcedo, Jose; Starbird, Thomas J.

    1994-01-01

    SEQ-GEN is a user-interactive computer program used to plan and generate a sequence of commands for spacecraft. Desired activities are specified by the user of SEQ-GEN; SEQ-GEN in turn expands these activities, deriving the spacecraft commands necessary to accomplish the desired activities. SEQ-GEN models the effects on the spacecraft of the commands, predicting the state as a function of time, flagging any conflicts and rule violations. These states, conflicts, and violations are viewable both graphically and textually at the user's request. SEQ-GEN also displays the entire sequence graphically, showing each requested activity as a bar on its graphical timeline. SEQ-GEN immediately revalidates the sequence, updating its models and calculations along with its displays based on these changes. Because it has the ability to recalculate spacecraft states immediately, the user is able to perform 'what-if' sessions easily. SEQ-GEN, a multimission tool, is adaptable to any flight project. A flight project writes its adaptation files containing project unique information including in its simplest form, only spacecraft commands. For more involved projects the adaptation files may also contain flight and mission rules, description of the spacecraft and ground models, and the definition of activities. SEQ-GEN operates at whatever level of detail the adaptation files imply. Simple adaptations are straight forward to do. There is, however, no limit to the complexity of activity definitions or of spacecraft models: both may involve unlimited logical decision points. Commands and activities may involve any number of parameters of a wide variety of data types, including integer, float, time, boolean, and character strings. SEQ-GEN will be used by the Mars Pathfinder, Cassini, and VIM (Voyager Interstellar Mission) project in an effort to speed up adaptation time and to keep sequence generation costs down. SEQ-GEN is hosted on UNIX workstations. It uses MOTIF and X for windowing

    Full Text Available Las poblaciones centroamericanas no han sido objeto de muchos estudios genéticos con la excepción de análisis esporádicos de la variación entre y dentro de los grupos amerindios y de origen africano ubicados en el área. No obstante, en los últimos 15 años se efectuaron investigaciones sistemáticas en este sentido incluyendo poblaciones mestizas, particularmente las de Costa Rica y Panamá. En los amerindios se efectuaron estudios detallados de su estructura genética y las relaciones filogenéticas entre poblaciones en un contexto regional y continental. De manera general estos grupos mantienen una baja diversidad genética. Por otra parte, estimativas de la mezcla génica en la población mestiza muestran diferencias dentro y entre los distintos países del área. Al Valle Central de Costa Rica se le atribuye la condición de aislado con una supuesta constitución genética homogénea favorable para los estudios de desequilibrio de ligamiento y asociaciones con algunas enfermedades hereditarias; sin embargo, los resultados obtenidos con relación el flujo génico direccional, la amalgama de etnias y otros componentes de su estructura como la variación temporal y espacial de la consanguinidad y la migración indican una mayor heterogeneidad. Se muestran los resultados y conclusiones obtenidas y se plantean las perspectivas y tendencias al mediano plazo que vinculan los enfoques y métodos de la epidemiología y la antropología genética y el estudio genético de poblaciones.

Análises de variância univariada e multivariada revelaram diferenças entre os genótipos. A distância generalizada de Mahalanobis indicou um alto grau de divergência genética. Os genótipos foram agrupados em três grupos. As características início do florescimento, 50% do florescimento, número de folhas e altura da inserção do capítulo contribuíram com grande parte da divergência genética observada. Por meio desses resultados, é possível identificar materiais divergentes e com características agronômicas complementares para o desenvolvimento de novos cultivares superiores.An investigation about the genetical diversity among fifteen sunflower genotypes using twelve agronomical characteristics was implanted at the Agronomic Institute, Campinas Brazil. Univariate and multivariate analyses of variance revealed the presence of differences among the genotypes. The generalized distance of Mahalanobis indicated the presence of genetic diversity. The genotypes were grouped into tree clusters. Among the investigated characteristics, the beginning of flowering, 50% flowering, leaf number and head height of chapter insertion exhibited high contribution towards genetic divergence. Through these studies it is possible to identify divergent material with further agronomical features for the development of new superior sunflower cultivars.

    Human GEN1 and yeast Yen1 are endonucleases with the ability to cleave Holliday junctions (HJs), which are proposed intermediates in recombination. In vivo, GEN1 and Yen1 function secondarily to Mus81, which has weak activity on intact HJs. We show that the genetic relationship is reversed in Drosophila, with Gen mutants having more severe defects than mus81 mutants. In vitro, DmGen, like HsGEN1, efficiently cleaves HJs, 5΄ flaps, splayed arms, and replication fork structures. We find that the cleavage rates for 5΄ flaps are significantly higher than those for HJs for both DmGen and HsGEN1, even in vast excess of enzyme over substrate. Kinetic studies suggest that the difference in cleavage rates results from a slow, rate-limiting conformational change prior to HJ cleavage: formation of a productive dimer on the HJ. Despite the stark difference in vivo that Drosophila uses Gen over Mus81 and humans use MUS81 over GEN1, we find the in vitro activities of DmGen and HsGEN1 to be strikingly similar. These findings suggest that simpler branched structures may be more important substrates for Gen orthologs in vivo, and highlight the utility of using the Drosophila model system to further understand these enzymes. © The Author(s) 2017.

    2008-01-01

    The Joint Planning and Development Office (JPDO), is charged by Congress with developing the concepts and plans for the Next Generation Air Transportation System (NextGen). The National Aviation Safety Strategic Plan (NASSP), developed by the Safety Working Group of the JPDO, focuses on establishing the goals, objectives, and strategies needed to realize the safety objectives of the NextGen Integrated Plan. The three goal areas of the NASSP are Safer Practices, Safer Systems, and Safer Worldwide. Safer Practices emphasizes an integrated, systematic approach to safety risk management through implementation of formalized Safety Management Systems (SMS) that incorporate safety data analysis processes, and the enhancement of methods for ensuring safety is an inherent characteristic of NextGen. Safer Systems emphasizes implementation of safety-enhancing technologies, which will improve safety for human-centered interfaces and enhance the safety of airborne and ground-based systems. Safer Worldwide encourages coordinating the adoption of the safer practices and safer systems technologies, policies and procedures worldwide, such that the maximum level of safety is achieved across air transportation system boundaries. This paper introduces the NASSP and its development, and focuses on the Safer Systems elements of the NASSP, which incorporates three objectives for NextGen systems: 1) provide risk reducing system interfaces, 2) provide safety enhancements for airborne systems, and 3) provide safety enhancements for ground-based systems. The goal of this paper is to expose avionics and air traffic management system developers to NASSP objectives and Safer Systems strategies.

    The Distributed Generation Market Demand model (dGen) is a geospatially rich, bottom-up, market-penetration model that simulates the potential adoption of distributed energy resources (DERs) for residential, commercial, and industrial entities in the continental United States through 2050. The National Renewable Energy Laboratory (NREL) developed dGen to analyze the key factors that will affect future market demand for distributed solar, wind, storage, and other DER technologies in the United States. The new model builds off, extends, and replaces NREL's SolarDS model (Denholm et al. 2009a), which simulates the market penetration of distributed PV only. Unlike the SolarDS model, dGen can model various DER technologies under one platform--it currently can simulate the adoption of distributed solar (the dSolar module) and distributed wind (the dWind module) and link with the ReEDS capacity expansion model (Appendix C). The underlying algorithms and datasets in dGen, which improve the representation of customer decision making as well as the spatial resolution of analyses (Figure ES-1), also are improvements over SolarDS.

    Full Text Available Genética genômica é um termo utilizado para representar o estudo de processos genéticos controladores de caracteres fenotípicos de herança complexa, a partir da análise conjunta de informação relativa a fenótipos, estruturas de parentesco, marcadores moleculares e expressão gênica. Estudos de genética genômica são utilizados, por exemplo, para a estimação da herdabilidade de níveis de transcrição, para o mapeamento de locos controladores da expressao gênica (eQTL, do inglês expression Quantitative Trait Loci, e para o estudo de redes regulatórias. Genética genômica geralmente envolve experimentos com microarrays, os quais são ainda bastante caros e trabalhosos, limitando o tamanho amostral e conseqüentemente o poder estatístico de tais estudos. Desta maneira, é essencial que tais experimentos sejam otimizados do ponto de vista do delineamento, a partir de criteriosa escolha das amostras (indivíduos a serem utilizadas, e do controle rigoroso dos vários fatores que podem afetar as variáveis-resposta de interesse. Outro ponto fundamental na condução de tais experimentos refere-se à marcação das amostras de mRNA com os fluoróforos e ao pareamento das mesmas em cada lâmina de microarray, os quais devem ser cuidadosamente planejados para que não haja confundimento entre estes efeitos e os fatores biológicos de interesse.

    Full Text Available Las expectativas puestas en el conocimiento genético exceden el ámbito de la medicina tradiciona, debido a que la intervención directa en la lotería natural demandaría el replanteamiento de conceptos centrales de justicia en salud: necesidades médicas, enfermedad, normalidad, e igualdad de oportunidades en el acceso a la salud. El punto en debate es sí el replanteo de dichos conceptos conlleva un cambio radical en las teorías de justicia (libertariana y/o liberal, mostrando su obsolescencia, o sí simplemente se requiere ampliar dichos conceptos claves por fallas estructurales en las mismas teorías. Como hipótesis general considero que los supuestos cuestionamientos, lejos de socavar las bases de las teorías de justicia, sólo ponen en evidencia sus viejos problemas estructurales. Por razones expositivas, dividiré la presentación tres partes. En la Primera parte, analizo la teoría libertariana, estudiando las contradicciones del modelo a través del impacto de la información genética en el seguro privado de salud. En la Segunda Parte, desarrollo la propuesta alternativa liberal rawlsianadanielsiana del modelo de seguro público, evaluando las implicaciones de la genética a partir de la crítica de su concepto biológico de enfermedad y su restricción al acceso a la salud por necesidades naturales. En la Tercera parte presento un modelo integral de necesidades y capacidades básicas, comprendiendo la prevención, el tratamiento y el mejoramiento moralmente permisible (genético y no genético.Mi aporte principal consiste en la elaboración de este modelo normativo integral de necesidades y capacidades para la regulación conjunta de la información y terapia genética con los restantes problemas de salud.

    Full Text Available La genética constituye uno de los mayores avances científicos del siglo XX, que comienza con el redescubrimiento de las leyes de Mendel y termina con la elaboración del primer "borrador" de la secuencia completa del genoma humano. La genética utiliza diferentes estrategias de investigación, como los estudios de gemelos y de adopción, que investigan la influencia de los factores genéticos y ambientales, y las estrategias para identificar genes específicos (genética molecular. Además del importante grado de discapacidad que generan, el impacto social de las enfermedades hereditarias es enorme, por su carácter potencialmente recurrente en una misma familia y por el elevado coste socio-sanitario derivado de la enorme carga de cuidados que requiere. El diagnóstico de las enfermedades hereditarias presenta características diferenciadoras muy significativas ya que el resultado de un diagnóstico genético tiene no sólo efectos sobre el paciente sino también sobre todos los individuos emparentados. Por tanto, la unidad de estudio en el diagnóstico genético es la familia y todo proceso de diagnóstico implica una investigación familiar. También conviene tener en cuenta que los protocolos de diagnóstico se desarrollan de forma paralela a la investigación básica y generalmente están poco estandarizados. Los resultados obtenidos en los estudios genéticos y el tipo de información que se facilita al paciente y a su familia deben ser matizados dentro del proceso del "consejo genético".Genetics is one of the greatest scientific advances of the XX century, which begins with the rediscovery of Mendel’s laws and culminates in the elaboration of the first "draft" of the complete sequence of the human genome.

    Full Text Available Dezoito genótipos de aveia foram testados quanto à dissimilaridade genética, com e sem o controle de moléstias da parte aérea. As variáveis avaliadas foram rendimento de grãos desaristados, peso de mil grãos, peso do hectolitro, estatura de planta e dias da emergência à floração. Foram empregados análises por variáveis canônicas e técnicas de agrupamento por meio dos métodos de otimização de Tocher e o método hierárquico do vizinho mais próximo, tendo como medida de dissimilaridade a distância generalizada de Mahalanobis. Pelos resultados, constatou-se significativa dissimilaridade genética entre os genótipos, indicando a existência de variabilidade para os caracteres avaliados. O método de Tocher e o método do vizinho mais próximo permitiram a separação dos genótipos em grupos distintos, possibilitando a identificação de futuros genitores que possam ser utilizados em cruzamentos artificiais que produzam progênies com maior heterose. Os caracteres que mais contribuíram para a dissimilaridade genética foram o peso do hectolitro e a estatura de planta.Eighteen oat genotypes were tested for genetic dissimilarity, with and without shoot disease control. The evaluated variables were grain yield, weight of one thousand grains, test weight, plant stature and days from emergence to flowering. Cannonical variables and clustering methods by Tocher's optimization test and the hierarchical method of nearest neighbor were employed, having as a measure of dissimilarity the general distance of Mahalanobis. The results showed a significant genetic dissimilarity among the genotypes, indicating the presence of genetic variability for the evaluated traits. Tocher's and nearest neighbor methods allowed the separation of genotypes in distinct groups, enabling the identification of potential parents for artificial crosses to obtain progenies with higher heterosis.

    2016-01-01

    Development of free/libre open source software is usually done by a community of people with an interest in the tool. For scientific software, however, this is less often the case. Most scientific software is written by only a few authors, often a student working on a thesis. Once the paper describing the tool has been published, the tool is no longer developed further and is left to its own device. Here we describe the broad, multidisciplinary community we formed around a set of tools for statistical genomics. The GenABEL project for statistical omics actively promotes open interdisciplinary development of statistical methodology and its implementation in efficient and user-friendly software under an open source licence. The software tools developed withing the project collectively make up the GenABEL suite, which currently consists of eleven tools. The open framework of the project actively encourages involvement of the community in all stages, from formulation of methodological ideas to application of software to specific data sets. A web forum is used to channel user questions and discussions, further promoting the use of the GenABEL suite. Developer discussions take place on a dedicated mailing list, and development is further supported by robust development practices including use of public version control, code review and continuous integration. Use of this open science model attracts contributions from users and developers outside the "core team", facilitating agile statistical omics methodology development and fast dissemination.

Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos da linhagem Redbro: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. As aves foram alojadas em 28 boxes, sendo 30 aves/boxe, em galpão de alvenaria com acesso a um piquete de 45m², com quatro repetições. O peso corporal individual dos frangos foi medido ao nascer, aos 14, 28, 42, 56, 70 e 84 dias de idade. Para a determinação das curvas de crescimento do peso corporal das aves, os dados coletados foram avaliados por meio dos modelos não lineares: Brody, Gompertz, Logístico, Richards e von Bertalanffy. Foi empregado o PROC NLIN do SAS, utilizando-se o método interativo de Gauss-Newton. Os critérios usados para escolha do modelo de melhor ajuste da curva de crescimento foram o coeficiente de determinação, o desvio padrão assintótico, o desvio médio absoluto dos resíduos e o índice assintótico. As análises para obtenção dos coeficientes alométricos foram realizadas por meio do PROC GLM do SAS para os genótipos Carijó, Colorpak, Pesadão Vermelho, Pescoço Pelado e Tricolor. Foram avaliados os pesos da carcaça, do peito, das coxas, das sobrecoxas, das pernas e das asas das aves abatidas aos 85 dias de idade. Apenas as equações propostas por Gompertz, von Bertalanffy e Logístico atingiram a convergência, e o modelo proposto por von Bertalanffy foi o mais adequado para descrever o crescimento dos genótipos de frangos caipiras. Todos os cortes avaliados apresentaram crescimento tardio em relação ao peso da carcaça em genótipos de frangos tipo caipira.

  18. From AWE-GEN to AWE-GEN-2d: a high spatial and temporal resolution weather generator

    2016-04-01

    A new weather generator, AWE-GEN-2d (Advanced WEather GENerator for 2-Dimension grid) is developed following the philosophy of combining physical and stochastic approaches to simulate meteorological variables at high spatial and temporal resolution (e.g. 2 km x 2 km and 5 min for precipitation and cloud cover and 100 m x 100 m and 1 h for other variables variable (temperature, solar radiation, vapor pressure, atmospheric pressure and near-surface wind). The model is suitable to investigate the impacts of climate variability, temporal and spatial resolutions of forcing on hydrological, ecological, agricultural and geomorphological impacts studies. Using appropriate parameterization the model can be used in the context of climate change. Here we present the model technical structure of AWE-GEN-2d, which is a substantial evolution of four preceding models (i) the hourly-point scale Advanced WEather GENerator (AWE-GEN) presented by Fatichi et al. (2011, Adv. Water Resour.) (ii) the Space-Time Realizations of Areal Precipitation (STREAP) model introduced by Paschalis et al. (2013, Water Resour. Res.), (iii) the High-Resolution Synoptically conditioned Weather Generator developed by Peleg and Morin (2014, Water Resour. Res.), and (iv) the Wind-field Interpolation by Non Divergent Schemes presented by Burlando et al. (2007, Boundary-Layer Meteorol.). The AWE-GEN-2d is relatively parsimonious in terms of computational demand and allows generating many stochastic realizations of current and projected climates in an efficient way. An example of model application and testing is presented with reference to a case study in the Wallis region, a complex orography terrain in the Swiss Alps.

    The genus Leptolyngbya Anagnostidis & Komárek (1988) was described from a set of strains identified as 'LPP-group B'. The morphology within this group is not particularly informative and underestimates the group's genetic diversity. In the present study, two new pseudanabaenacean genera related to Leptolyngbya morphotypes, Pantanalinema gen. nov. and Alkalinema gen. nov., are described under the provisions of the International Code of Nomenclature for Algae, Fungi and Plants, based on a polyphasic approach. Pantanalinema gen. nov. (type species Pantanalinema rosaneae sp. nov.) has sheaths and trichomes with slight gliding motility, which distinguish this genus from Alkalinema gen. nov. (type species Alkalinema pantanalense sp. nov.), which possesses trichomes arranged in an ornate (interwoven) pattern. 16S rRNA gene sequences of strains of Pantanalinema and Alkalinema exhibited low identity to each other (≤91.6 %) and to other sequences from known pseudanabaenacean genera (≤94.3 and 93.7 %, respectively). In a phylogenetic reconstruction, six sequences from strains of Pantanalinema and four from strains of Alkalinema formed two separate and robust clades (99 % bootstrap value), with the genera Oculatella and Phormidesmis, respectively, as the closest related groups. 16S-23S rRNA intergenic spacer sequences and secondary structures of strains of Pantanalinema and Alkalinema did not correspond to any previous descriptions. The strains of Pantanalinema and Alkalinema were able to survive and produce biomass at a range of pH (pH 4-11) and were also able to alter the culture medium to pH values ranging from pH 8.4 to 9.9. These data indicate that cyanobacterial communities in underexplored environments, such as the Pantanal wetlands, are promising sources of novel taxa.

    Full Text Available A new arthrotardigrade, Prostygarctus aculeatus gen. nov., sp. nov. is described from intertidal meiobenthos samples collected at Ofir beach, Esposende, North of Portugal. The new species, an armoured arthrotardigrade of the family Stygarctidae, is easily distinguished from all the other stygarctids by an unusual caudal apparatus, which consists of a very long medial spine with two lateral furca-like processes. It is also characterised by the presence of backwardly directed dorsal spines and a pair of ventral spines. Furthermore, it has four digits on each leg, ending in simple claws. The morphological peculiarities exhibited by the new species justify the establishment of a new genus and will provide useful insights to help develop our understanding of the phylogenetic relationships of armoured arthrotardigrades.

    2012-03-01

    Chromerida are photoautotrophic alveolates so far only isolated from corals in Australia. It has been shown that these secondary plastid-containing algae are closely related to apicomplexan parasites and share various morphological and molecular characters with both Apicomplexa and Dinophyta. So far, the only known representative of the phylum was Chromera velia. Here we provide a formal description of another chromerid, Vitrella brassicaformis gen. et sp. nov., complemented with a detailed study on its ultrastructure, allowing insight into its life cycle. The novel alga differs significantly from the related chromerid C. velia in life cycle, morphology as well as the plastid genome. Analysis of photosynthetic pigments on the other hand demonstrate that both chromerids lack chlorophyll c, the hallmark of phototrophic chromalveolates. Based on the relatively high divergence between C. velia and V. brassicaformis, we propose their classification into distinct families Chromeraceae and Vitrellaceae. Moreover, we predict a hidden and unexplored diversity of the chromerid algae. © 2011 Elsevier GmbH.

    2007-09-01

    Full Text Available The “Gen2” specification for UHF passive RFID systems released by EPCglobal has become an intense research interest. A Gen2 tag derives its power from the RF wave emitted by a Gen2 RFID reader and responds its modulated backscatter signals to the reader. Due to the large propagation loss, the accessible range of a Gen2 tag is hence limited. Moreover, the readability of a Gen2 tag is often influenced by the multipath fading problem. In order to mitigate the problems, a multi-carrier UHF passive RFID system utilizing the frequency diverse backscatter ability of a Gen2 tag is proposed in a prior work. In this work, a thorough analysis of the system is given. Especially, the appropriate powers of the transceiver and CWEs are derived to make the system more feasible in practical applications.

Se tendrán en cuenta estos complejos como representativos de afinidades que se establecen a partir de estrechas relaciones entre las etnias, no sólo por la lengua, sino también por las características de sus sistemas productivos, religiosidad y organización. En base a las frecuencias génicas publicadas correspondientes a los siguientes alelos: I*A, I*B, I*O; M, N, S, s; Dia , Dib; P1, P2; C, c; D, d, E, e; Le, le; Fya, Fyb; Jka, Jkb; K y k se construyeron tablas de frecuencias. Se estimaron los coeficientes de distancias genéticas que fueron analizados y posteriormente incluídos en la construcción de un fenograma de los grupos de estudio, mediante agrupaciones (Sahn Cluster secuenciales, aglomerativas, jerárquicas y anidadas. De acuerdo a la información recopilada de las frecuencias de los 25 alelos estudiados en trece poblaciones de aborígenes del NOA y Paraguay, las distancias genéticas obtenidas reflejan los caracteres lingüístico-culturales.

    extracted a data set from the A. thaliana entries in GenBank. A number of simple `sanity' checks, based on the nature of the data, revealed an alarmingly high error rate. More than 15% of the most important entries extracted did contain erroneous information. In addition, a number of entries had directly...... common. It is proposed that the level of error correction should be increased and that gene structure sanity checks should be incorporated - also at the submitter level - to avoid or reduce the problem in the future. A non-redundant and error corrected subset of the data for A. thaliana is made available...

    We present a framework, called TrayGen, to generate tray designs for the exhibition and packaging of a collection of objects. Based on principles from shape perception and visual merchandising, we abstract a number of design guidelines on how to organize the objects on the tray for the exhibition of their individual features and mutual relationships. Our framework realizes these guidelines by analyzing geometric shapes of the objects and optimizing their arrangement. We demonstrate that the resultant tray designs not only save space, but also highlight the characteristic of each object and the inter-relations between objects. © 2013 The Eurographics Association and John Wiley & Sons Ltd.

    In this paper, the taxonomy of the genus Arthrobacter is discussed, from its first description in 1947 to the present state. Emphasis is given to intrageneric phylogeny and chemotaxonomic characteristics, concentrating on quinone systems, peptidoglycan compositions and polar lipid profiles. Internal groups within the genus Arthrobacter indicated from homogeneous chemotaxonomic traits and corresponding to phylogenetic grouping and/or high 16S rRNA gene sequence similarities are highlighted. Furthermore, polar lipid profiles and quinone systems of selected species are shown, filling some gaps concerning these chemotaxonomic traits. Based on phylogenetic groupings, 16S rRNA gene sequence similarities and homogeneity in peptidoglycan types, quinone systems and polar lipid profiles, a description of the genus Arthrobacter sensu lato and an emended description of Arthrobacter roseus are provided. Furthermore, reclassifications of selected species of the genus Arthrobacter into novel genera are proposed, namely Glutamicibacter gen. nov. (nine species), Paeniglutamicibacter gen. nov. (six species), Pseudoglutamicibacter gen. nov. (two species), Paenarthrobacter gen. nov. (six species) and Pseudarthrobacter gen. nov. (ten species).

    The increasing availability of genetic sequence data associated with explicit geographic and ecological information is offering new opportunities to study the processes that shape biodiversity. The generation and testing of hypotheses using these data sets requires effective tools for mathematical and visual analysis that can integrate digital maps, ecological data, and large genetic, genomic, or metagenomic data sets. GenGIS is a free and open-source software package that supports the integration of digital map data with genetic sequences and environmental information from multiple sample sites. Essential bioinformatic and statistical tools are integrated into the software, allowing the user a wide range of analysis options for their sequence data. Data visualizations are combined with the cartographic display to yield a clear view of the relationship between geography and genomic diversity, with a particular focus on the hierarchical clustering of sites based on their similarity or phylogenetic proximity. Here we outline the features of GenGIS and demonstrate its application to georeferenced microbial metagenomic, HIV-1, and human mitochondrial DNA data sets. PMID:19635847

    We extend the 2 nd Gen Discrete Wavelet Transform (DWT) of Swelden to the Next Generations (NG) Digital Wavelet Transform (DWT) preserving the statistical salient features. The lossless NG DWT accomplishes the data compression of "wellness baseline profiles (WBP)" of aging population at homes. For medical monitoring system at home fronts we translate the military experience to dual usage of veterans & civilian alike with the following three requirements: (i) Data Compression: The necessary down sampling reduces the immense amount of data of individual WBP from hours to days and to weeks for primary caretakers in terms of moments, e.g. mean value, variance, etc., without the artifacts caused by FFT arbitrary windowing. (ii) Lossless: our new NG_DWT must preserve the original data sets. (iii) Phase Transition: NG_DWT must capture the critical phase transition of the wellness toward the sickness with simultaneous display of local statistical moments. According to the Nyquist sampling theory, assuming a band-limited wellness physiology, we must sample the WBP at least twice per day since it is changing diurnally and seasonally. Since NG_DWT, like the 2 nd Gen, is lossless, we can reconstruct the original time series for the physicians' second looks. This technique of NG_DWT can also help stock market day-traders monitoring the volatility of multiple portfolios without artificial horizon artifacts.

    Full Text Available This paper addresses claims that dreams can be a source of personal insight. Whereas there has been anecdotal backing for such claims, there is now tangential support from findings of the facilitative effect of sleep on cognitive insight, and of REM sleep in particular on emotional memory consolidation. Furthermore, the presence in dreams of metaphorical representations of waking life indicates the possibility of novel insight as an emergent feature of such metaphorical mappings. In order to assess whether personal insight can occur as a result of the consideration of dream content, 11 dream group discussion sessions were conducted which followed the Ullman Dream Appreciation technique, one session for each of 11 participants (10 females, 1 male; mean age = 19.2 years. Self-ratings of deepened self-perception and personal gains from participation in the group sessions showed that the Ullman technique is an effective procedure for establishing connections between dream content and recent waking life experiences, although wake life sources were found for only 14% of dream report text. The mean Exploration-Insight score on the Gains from Dream Interpretation questionnaire was very high and comparable to outcomes from the well-established Hill (1996 therapist-led dream interpretation method. This score was associated between-subjects with pre-group positive Attitude Toward Dreams. The need to distinguish ‘aha’ experiences as a result of discovering a waking life source for part of a dream, from ‘aha’ experiences of personal insight as a result of considering dream content, is discussed. Difficulties are described in designing a control condition to which the dream report condition can be compared.

Observando os resultados, foi possível visualizar que a grande variação (59,0% no comportamento dos genótipos ao longo dos anos é atribuída principalmente à variância do ambiente (σ2a=436.245. Houve diferença significativa entre genótipos para todos os ambientes. Porém, a diferença entre eles foi constante, ou seja, os genótipos não responderam de modo diferenciado frente aos ambientes. A interação genótipo*ambiente (σ2ga=1.368 responde preponderantemente por uma ínfima alteração (0,2% na variação fenotípica, não discriminando de genótipos de feijão quanto ao rendimento de grãos em Lages/SC. Este fato favorece programas de melhoramento vegetal, onde a interação genótipo*ambiente poderia dificultar a distinção, seleção e recomendação de constituições genotípicas superiores. Nessa situação, processos de recomendação de cultivares (ensaio de valor de cultivo e uso - VCU que mantenham os mesmos genótipos dispensam avaliações sucessivas, pois o ranqueamento é paralelo no decorrer dos anos.

    2012-01-01

    GenASiS (General Astrophysical Simulation System) is a new code being developed initially and primarily, though by no means exclusively, for the simulation of core-collapse supernovae on the world's leading capability supercomputers. Using the features of Fortran 2003 that allow for object-oriented programming, its classes are grouped into three major divisions: (1) Basics, which contains some basic utilitarian functionality for large-scale simulations on distributed-memory supercomputers; (2) Mathematics, which includes generic mathematical constructs and solvers that are as agnostic as possible with regard to the specifics of any particular system; and (3) Physics, which sets up physical spaces associated with various theories of spacetime (including gravity), defines various forms of stress-energy, and combines these into `universes.' To provide a foundation for subsequent papers focusing on the implementation of various pieces of physics needed for the simulation of core-collapse supernovae and other astr...

    "Astrogen", the Astronomy Genealogy Project, is in the development stage. Patterned after the Mathematics Genealogy Project at http://genealogy.math.ndsu.nodak.edu, it will eventually include most of the world's astronomers, past and present, and provide information about their years of life, highest degrees, universities, and thesis titles. There will also be links to online theses, home pages, and obituaries when these are available. Although a few details remain to be worked out before it becomes public, it is possible to make some use of what has already been compiled. I will give an example, comparing graduates of Harvard University, the University of California at Berkeley, and the University of Chicago from different decades, with information about their professional careers and publication records. The author welcomes queries about AstroGen and is seeking more participants.

    When it comes to workplace preferences, Generation Y workers closely resemble Baby Boomers. Because these two huge cohorts now coexist in the workforce, their shared values will hold sway in the companies that hire them. The authors, from the Center for Work-Life Policy, conducted two large-scale surveys that reveal those values. Gen Ys and Boomers are eager to contribute to positive social change, and they seek out workplaces where they can do that. They expect flexibility and the option to work remotely, but they also want to connect deeply with colleagues. They believe in employer loyalty but desire to embark on learning odysseys. Innovative firms are responding by crafting reward packages that benefit both generations of workers--and their employers.

  9. Commissioning and Performance Analysis of WhisperGen Stirling Engine

    Science.gov (United States)

    Pradip, Prashant Kaliram

    Stirling engine based cogeneration systems have potential to reduce energy consumption and greenhouse gas emission, due to their high cogeneration efficiency and emission control due to steady external combustion. To date, most studies on this unit have focused on performance based on both experimentation and computer models, and lack experimental data for diversified operating ranges. This thesis starts with the commissioning of a WhisperGen Stirling engine with components and instrumentation to evaluate power and thermal performance of the system. Next, a parametric study on primary engine variables, including air, diesel, and coolant flowrate and temperature were carried out to further understand their effect on engine power and efficiency. Then, this trend was validated with the thermodynamic model developed for the energy analysis of a Stirling cycle. Finally, the energy balance of the Stirling engine was compared without and with heat recovery from the engine block and the combustion chamber exhaust.

    Full Text Available En años recientes se ha podido definir con gran exactitud la existencia de alteraciones genéticas específicas en una gran variedad de síndromes epilépticos tradicionales. Es decir, por vez primera se ha podido relacionar de manera contundente y predecible la presencia de alteraciones genómicas y/o proteómicas con síndromes epilépticos antes considerados como "idiopáticos". La gran mayoría de dichos defectos han sido encontrados en genes codificadores para canales iónicos y/o receptores de membrana, lo cual en cierto modo confirma la ya antes postulada relevancia que estas estructuras tienen en la actividad electroquímica espontánea neuronal cuyo desajuste conllevaría a ciertas formas de epilepsia. Esta revisión se centra en los aspectos genéticos y clínicos de dichas condiciones y alteraciones. También se revisarán brevemente los estudios más relevantes de la literatura médica según los cuales -aun a pesar de no haberse definido con la misma exactitud el tipo de anomalías etiológicas- puede tranquilamente inferirse el gran componente genético que parece subyacer a la etiología de las epilepsias. Por ultimo se enfatizará en que a pesar de dichos descubrimientos, su aplicación en la práctica clínica diaria aun es muy limitada, no solo por la relativa rareza de algunos de tales síndromes neurológicos sino también por la poca relevancia que hasta ahora ellos han tenido en el manejo médico rutinario de la mayoría de los pacientes. Las posibilidades inmediatas de tales avances -incluida la farmacogenómica-, así como los posibles conflictos éticos en que se podría incurrir serán también brevemente discutidos.In the last few years, the presence of specific genetic abnormalities leading to some of the classical epileptic syndromes has been clearly elucidated.

  13. Molecular-Level Insights into Photocatalysis from Scanning Probe Microscopy Studies on TiO2(110)

    Energy Technology Data Exchange (ETDEWEB)

    Henderson, Michael A.; Lyubinetsky, Igor

    2013-06-12

    The field of heterogeneous photocatalysis has grown considerably in the decades since Fujishima and Honda's ground-breaking publications of photoelectrochemistry on TiO2. Numerous review articles continue to point to both progress made in the use of heterogeneous materials (such as TiO2) to perform photoconversion processes, and the many opportunities and challenges in heterogeneous photocatalysis research such as solar energy conversion and environmental remediation. The past decade has also seen an increase in the use of molecular-level approaches applied to model single crystal surfaces in an effort to obtain new insights into photocatalytic phenomena. In particular, scanning probe techniques (SPM) have enabled researchers to take a ‘nanoscale’ approach to photocatalysis that includes interrogation of the reactivities of specific sites and adsorbates on a model photocatalyst surface. The rutile TiO2(110) surface has become the prototypical oxide single crystal surface for fundamental studies of many interfacial phenomena. In particular, TiO2(110) has become an excellent model surface for probing photochemical and photocatalytic reactions at the molecular level. A variety of experimental approaches have emerged as being ideally suited for studying photochemical reactions on TiO2(110), including desorption-oriented approaches and electronic spectroscopies, but perhaps the most promising techniques for evaluating site-specific properties are those of SPM. In this review, we highlight the growing use of SPM techniques in providing molecular-level insights into surface photochemistry on the model photocatalyst surface of rutile TiO2(110). Our objective is to both illustrate the unique knowledge that scanning probe techniques have already provided the field of photocatalysis, and also to motivate a new generation of effort into the use of such approaches to obtain new insights into the molecular level details of photochemical events occurring at interfaces

  14. Death: 'nothing' gives insight.

    Science.gov (United States)

    Ettema, Eric J

    2013-08-01

    According to a widely accepted belief, we cannot know our own death--death means 'nothing' to us. At first sight, the meaning of 'nothing' just implies the negation or absence of 'something'. Death then simply refers to the negation or absence of life. As a consequence, however, death has no meaning of itself. This leads to an ontological paradox in which death is both acknowledged and denied: death is … nothing. In this article, I investigate whether insight into the ontological paradox of the nothingness of death can contribute to a good end-of-life. By analysing Aquinas', Heidegger's and Derrida's understanding of death as nothingness, I explore how giving meaning to death on different ontological levels connects to, and at the same time provides resistance against, the harsh reality of death. By doing so, I intend to demonstrate that insight into the nothingness of death can count as a framework for a meaningful dealing with death.

    Binderoboletus segoi gen. and sp. nov., Guyanaporus albipodus gen. and sp. nov. and Singerocomus rubriflavus gen. and sp. nov. (Boletaceae, Boletales, Basidiomycota) are described from the Pakaraima Mountains and adjacent lowlands of Guyana. Xerocomus inundabilis, originally described from the central Brazilian Amazon and based solely on the type collection, is redescribed from numerous collections from Guyana and transferred into Singerocomus. These boletes occur in Neotropical forests dominated by ectomycorrhizal trees in the genera Dicymbe (Fabaceae subfam. Caesalpinioideae), Aldina (Fabaceae subfam. Papilionoideae) and Pakaraimaea (Dipterocarpaceae). Three of the species were repeatedly found in a multiyear sporocarp survey in Dicymbe corymbosa-monodominant forest. Macromorphological, micromorphological, habitat and multilocus DNA sequence data are provided for each species. A molecular phylogenetic analysis based on a large taxon set across the Boletaceae justifies erection of the new genera.

    Hand-held optical imagers are developed by various researchers towards reflectance-based spectroscopic imaging of breast cancer. Recently, a Gen-1 handheld optical imager was developed with capabilities to perform two-dimensional (2-D) spectroscopic as well as three-dimensional (3-D) tomographic imaging studies. However, the imager was bulky with poor surface contact (~30%) along curved tissues, and limited sensitivity to detect targets consistently. Herein, a Gen-2 hand-held optical imager that overcame the above limitations of the Gen-1 imager has been developed and the instrumentation described. The Gen-2 hand-held imager is less bulky, portable, and has improved surface contact (~86%) on curved tissues. Additionally, the forked probe head design is capable of simultaneous bilateral reflectance imaging of both breast tissues, and also transillumination imaging of a single breast tissue. Experimental studies were performed on tissue phantoms to demonstrate the improved sensitivity in detecting targets using the Gen-2 imager. The improved instrumentation of the Gen-2 imager allowed detection of targets independent of their location with respect to the illumination points, unlike in Gen-1 imager. The developed imager has potential for future clinical breast imaging with enhanced sensitivity, via both reflectance and transillumination imaging.

    2016-01-01

    Previous studies showed that liberals and conservatives differ in cognitive style. Liberals are more flexible, and tolerant of complexity and novelty, whereas conservatives are more rigid, are more resistant to change, and prefer clear answers. We administered a set of compound remote associate problems, a task extensively used to differentiate problem-solving styles (via insight or analysis). Using this task, several researches have proven that self-reports, which differentiate between insight and analytic problem-solving, are reliable and are associated with two different neural circuits. In our research we found that participants self-identifying with distinct political orientations demonstrated differences in problem-solving strategy. Liberals solved significantly more problems via insight instead of in a step-by-step analytic fashion. Our findings extend previous observations that self-identified political orientations reflect differences in cognitive styles. More specifically, we show that type of political orientation is associated with problem-solving strategy. The data converge with previous neurobehavioural and cognitive studies indicating a link between cognitive style and the psychological mechanisms that mediate political beliefs.

Dado a importância da cultura da ameixeira para a região Sul do Brasil, o presente trabalho teve por finalidade contribuir para a caracterização genético-molecular de 17 cultivares. As cultivares foram analisadas com 12 marcadores RAPD, que produziram 187 polimorfismos. O marcador OP A20 foi o mais polimórfico, produzindo 26 perfis diferentes. A análise de agrupamento, realizada com o método UPGMA, produziu um dendrograma que permitiu uma clara separação das cultivares em três grupos, correspondentes às suas respectivas espécies, Prunus salicina, Prunus domestica e Prunus cerasifera. O alto grau de polimorfismo detectado pelos marcadores RAPD confirma o potencial da técnica na análise de "fingerprinting" e sua utilidade na estimativa da variabilidade genética entre cultivares de ameixeira.

    Full Text Available A new relative of the chrysophyte genus Chrysopodocystis was found in Tenerife and termed Guanchochroma wildpretii. This unicellular alga was most noticeably discernible from Chrysopodocystis socialis (the only species of this genus by the presence of a cyst-like stage with a multilayered lorica, which also functions as a dispersal unit and shows secondary wall growth. Secondary expansion of loricae (cell casings not involved in cell division, usually with a more or less pronounced opening has never been observed previously and marks a unique feature of the new taxon. Plastids are non-randomly distributed within cells of G. wildpretii. 18S rRNA gene analyses identified the two species as sister lineages and placed them in a monophyletic group with the Synchromophyceae, a heterokont algal (Ochrophyta class characterized by the presence of chloroplast complexes. Yet, neither Chrysopodocystis nor Guanchochroma showed this feature in ultrastructure analyses. Additionally, their 18S rRNA genes possessed distinct inserts, the highest GC-content known for Ochrophyta and exceptionally long branches on the Ochrophyta 18S rDNA phylogenetic tree, suggesting substantially increased substitution rates along their branch compared to Synchromophyceae. Plastid marker data (rbcL recovered a monophyletic clade of Chrysopodocystis, Guanchochroma and Synchromophyceae as well, yet with lower supports for internal split order due to limited resolution of the marker. Evidence for the sequence of events leading to the formation of the plastid complex of Synchromophyceae still remains ambiguous because of the apparently short timeframe in which they occurred.

    A Gram-positive staining, rod-shaped, non-motile, spore-forming obligately anaerobic bacterium, designated CRIBT, was isolated from the gastro-intestinal tract of a rat and characterized. The major cellular fatty acids of strain CRIBT were saturated and unsaturated straight-chain C12-C19 fatty acids, with C16:0 being the predominant fatty acid. The polar lipid profile comprised six glycolipids, four phospholipids and one lipid that did not stain with any of the specific spray reagents used. The only quinone was MK-6. The predominating cell-wall sugars were glucose and galactose. The peptidoglycan type of strain CRIBT was A1σ lanthionine-direct. The genomic DNA G+C content of strain CRIBT was 28.1 mol%. On the basis of 16S rRNA gene sequence similarity, strain CRIBT was most closely related to a number of species of the genus Clostridium, including Clostridium lituseburense (97.2%), Clostridium glycolicum (96.2%), Clostridium mayombei (96.2%), Clostridium bartlettii (96.0%) and Clostridium irregulare (95.5%). All these species show very low 16S rRNA gene sequence similarity (gen. nov., is proposed. The novel isolate CRIBT (=DSM 25109T=NIZO 4048T) is proposed as the type strain of the type species, Romboutsia ilealis gen. nov., sp. nov., of the proposed novel genus. It is proposed that C. lituseburense is transferred to this genus as Romboutsia lituseburensis comb. nov. Furthermore, the reclassification into novel genera is proposed for C. bartlettii, as Intestinibacter bartlettii gen. nov., comb. nov. (type species of the genus), C. glycolicum, as Terrisporobacter glycolicus gen. nov., comb. nov. (type species of the genus), C. mayombei, as Terrisporobacter mayombei gen. nov., comb. nov., and C. irregulare, as Asaccharospora irregularis gen. nov., comb. nov. (type species of the genus), on the basis of additional data collected in this study. In addition, an emendation of the species Peptostreptococcus anaerobius and the order Eubacteriales is provided.

O trabalho foi conduzido no período de setembro a dezembro de 2007 no município de Fortaleza-CE. O delineamento utilizado foi o aleatorizado em blocos com três repetições, onde os genótipos e cultivares foram considerados tratamentos. Na análise de desempenho verificou-se diferença entre as médias dos genótipos avaliados para as características: altura da planta, diâmetro do colo, surgimento da primeira inflorescência, antese, média de umbeletes/umbela, início e término do amadurecimento dos frutos. Entretanto, para as características agronômicas, número de folhas aproveitáveis e peso de cem frutos, não se verificou diferença entre as médias dos genótipos avaliados em relação às cultivares comerciais. Quanto à divergência, o genótipo 1, proveniente da região litorânea de Caucaia, foi o mais divergente, podendo ser usado em cruzamentos com os demais genótipos para a obtenção de populações segregantes. Os genótipos mais similares foram o Verdão-SF177 e o genótipo proveniente de Juazeiro. Os resultados do agrupamento não mostraram relação com as diferentes localizações geográficas dos genótipos avaliados.Five genotypes of coriander (Coriandrum sativum from different regions of Ceara-Brazil and two cultivars were assessed with the objective to identify genotypes with agronomic potential for use in breeding program using performance analysis and genetic divergence.

    Full Text Available A obesidade definida como a acumulação excessiva de gordura corporal deriva de um desequilíbrio crônico entre a energia ingerida e a energia gasta. Neste desequilíbrio podem estar implicados diversos fatores relacionados com o estilo de vida (dieta e exercício físico, alterações neuro-endócrinas, juntamente com um componente hereditário. O componente genético constitui um fator determinante de algumas doenças congênitas e um elemento de risco para diversas doenças crônicas como diabetes, osteoporose, hipertensão, câncer, obesidade, entre outras. O aumento da prevalência da obesidade em quase todos os países durante os últimos anos, parece indicar que existe uma predisposição ou susceptibilidade genética para a obesidade, sobre a qual atuam os fatores ambientais relacionados com os estilos de vida, em que se incluem principalmente os hábitos alimentares e a atividade física. A utilização de modelos animais de obesidade, a transferência génica e os estudos de associação e ligamento, permitiram a identificação de vários genes implicados na obesidade.Obesity, defined as an excessive body fat accumulation, is caused by a chronic imbalance between energy intake and energy expenditure. Several factors have been associated with this energy imbalance, such as life style (diet and physical activity, neuroendocrine disorders, together with the genetic background. The genetic background is a major determinant factor of some congenital diseases and a risk factor for some chronic disorders, such as diabetes, osteoporosis, hypertension, cancer, obesity, and others. The increased prevalence of obesity in most countries during the last years, seems to indicate that there is a genetic predisposition or susceptibility to be obese which is increased by environmental and life style factors, mainly by food habits and physical in activity.

    2012-01-01

    In this paper, the second in a series, we document the algorithms and solvers for compressible nonrelativistic hydrodynamics implemented in GenASiS (General Astrophysical Simulation System)---a new code being developed initially and primarily, though by no means exclusively, for the simulation of core-collapse supernovae. In the Mathematics division of GenASiS we introduce Solvers, which includes finite-volume updates for generic hyperbolic BalanceEquations and ordinary differential equation integration Steps. We also introduce the Physics division of GenASiS; this extends the Manifolds division of Mathematics into physical Spaces, defines StressEnergies, and combines these into Universes. We benchmark the hydrodynamics capabilities of GenASiS against many standard test problems; the results illustrate the basic competence of our implementation, demonstrate the manifest superiority of the HLLC over the HLL Riemann solver in a number of interesting cases, and provide preliminary indications of the code's abili...

    A new monotypic wolf spider genus, Ovia gen. nov. is proposed to accommodate a misplaced species: Pardosa procurva Yu & Song, 1988. Ovia procurva comb. nov. is redescribed, illustrated and designated as the type species for the genus. The subfamily placement of the new genus is discussed and it is considered as a member of Lycosinae Sundevall, 1833 and possibly closely related to Alopecosa Simon, 1885. The presence of an apical process (spur) on the median apophysis is proposed as the putative synapomorphy of Ovia gen. nov. The possible sister-taxon relationship of Ovia gen. nov. with Alopecosa is discussed and evidence on the occurrence of sexual dimorphism and mating plug within the genus are presented. Ovia gen. nov. is assumed to be of Holarctic origin, from which it has migrated to the Indomalayan region. Additionally, a current distribution map for the genus is provided.

    2007-04-01

    System Dynamics is a computer-aided approach to evaluating the interrelationships of different components and activities within complex systems. Recently, System Dynamics models have been developed in areas such as policy design, biological and medical modeling, energy and the environmental analysis, and in various other areas in the natural and social sciences. The real power of System Dynamic modeling is gaining insights into total system behavior as time, and system parameters are adjusted and the effects are visualized in real time. System Dynamic models allow decision makers and stakeholders to explore long-term behavior and performance of complex systems, especially in the context of dynamic processes and changing scenarios without having to wait decades to obtain field data or risk failure if a poor management or design approach is used. The Idaho National Laboratory recently has been developing a System Dynamic model of the US Nuclear Fuel Cycle. The model is intended to be used to identify and understand interactions throughout the entire nuclear fuel cycle and suggest sustainable development strategies. This paper describes the basic framework of the current model and presents examples of useful insights gained from the model thus far with respect to sustainable development of nuclear power.

    Two strains of Gram-stain-positive, catalase-negative, tetrad-forming cocci, C01(T) and C02, were isolated in Thailand from fish sauce. They were facultatively anaerobic, non-motile and non-spore-forming bacteria. These strains produced l-lactic acid from glucose. They grew at pH 5.0-9.0, at 15-40 °C and in the presence of 10 % (w/v) NaCl. The dominant fatty acid was C(18 : 1)ω9c. The DNA G+C contents of strains C01(T) and C02 were 38.6 and 38.7 mol%, respectively. Strain C01(T) was related most closely to Desemzia incerta DSM 20581(T), with a 16S rRNA gene sequence similarity of 96.9 %. The strains could be distinguished clearly from D. incerta DSM 20581(T) based on cell morphology, physiological and biochemical characteristics and low levels of DNA-DNA relatedness. On the basis of the data presented, strains C01(T) and C02 are considered to represent a novel species of a new genus in the Bacillus-Lactobacillus cluster, for which the name Pisciglobus halotolerans gen. nov., sp. nov. is proposed. The type strain of Pisciglobus halotolerans is C01(T) ( = KCTC 13150(T)  = TISTR 1958(T)  = PCU 316(T)).

    Full Text Available Nos últimos anos a equideocultura deu um salto qualitativo, havendo hoje, no mercado, animais de alto valor e geneticamente superiores. Isso é possível, em grande parte, devido aos avanços na área da genética animal, os quais permitem identificar, não apenas anomalias, mas também diversos genes de interesse econômico. Com o auxílio da citogenética pode-se identificar indivíduos com alterações no número ou na estrutura dos cromossomos, o que em muitos casos afeta principalmente a reprodução. Também a confirmação de genealogia, anteriormente feita por tipagem sangüínea e atualmente por testes de DNA, tem papel extremamente importante, não apenas por garantir a ascendência dos animais, mas também porque um pedigree confiável pode permitir ao criador identificar a origem de problemas genéticos em seu rebanho e reduzi-los ou mesmo, eliminá-los. Ainda com as ferramentas da biologia molecular, podemos hoje, identificar indivíduos que apresentam genes desejáveis ou indesejáveis, o que nos permite selecioná-los precocemente, reduzindo assim, os custos do produtor e aumentando o valor agregado dos animais. Entre tais genes podemos destacar os que identificam portadores ou afetados por mutações genéticas indesejáveis como: SCID (Síndrome da Imunodeficiência Combinada, HYPP (Parilisa Hipercalêmica, HERDA (Astenia Dérmica Regional Hereditária Eqüina, etc. Também a identificação dos genes que determinam a cor ou padrão da pelagem já pode ser feita direta ou indiretamente (por meio de marcadores genéticos, como é o caso dos genes para as pelagens Overo, Tobiano, etc. Com os avanços no estudo do genoma eqüino muito mais estará disponível em breve, o que certamente só trará maiores contribuições à equideocultura mundial.In the last few years the horse breeding industry is achieving significant progresses producing animals of high commercial value and genetically superior.

    Homology inference is pivotal to evolutionary biology and is primarily based on significant sequence similarity, which, in general, is a good indicator of homology. Algorithms have also been designed to utilize conservation in gene order as an indication of homologous regions. We have developed GenFamClust, a method based on quantification of both gene order conservation and sequence similarity. In this study, we validate GenFamClust by comparing it to well known homology inference algorithms on a synthetic dataset. We applied several popular clustering algorithms on homologs inferred by GenFamClust and other algorithms on a metazoan dataset and studied the outcomes. Accuracy, similarity, dependence, and other characteristics were investigated for gene families yielded by the clustering algorithms. GenFamClust was also applied to genes from a set of complete fungal genomes and gene families were inferred using clustering. The resulting gene families were compared with a manually curated gold standard of pillars from the Yeast Gene Order Browser. We found that the gene-order component of GenFamClust is simple, yet biologically realistic, and captures local synteny information for homologs. The study shows that GenFamClust is a more accurate, informed, and comprehensive pipeline to infer homologs and gene families than other commonly used homology and gene-family inference methods.

    Two bacterial strains, KIS66-7(T) and 5GH26-15(T), were isolated from soil samples collected in the South Korean cities of Tongyong and Gongju, respectively. Both strains were aerobic, Gram-stain-positive, mesophilic, flagellated, and rodshaped. A phylogenetic analysis revealed that both strains belonged to the family Microbacteriaceae of the phylum Actinobacteria. The 16S rRNA gene sequence of strain KIS66-7(T) had the highest similarities with those of Labedella gwakjiensis KSW2-17(T) (97.3%), Cryobacterium psychrophilum DSM 4854T (97.2%), Leifsonia lichenia 2Sb(T) (97.2%), Leifsonia naganoensis JCM 10592(T) (97.0%), and Cryobacterium mesophilum MSL-15(T) (97.0%). Strain 5GH26-15(T) showed the highest sequence similarities with Leifsonia psychrotolerans LI1T (97.4%) and Schumannella luteola KHIAT (97.1%). The 16S rRNA gene sequence from KIS66-7(T) exhibited 96.4% similarity with that from 5GH26-15(T). Strain KIS66-7(T) contained a B2γ type peptidoglycan structure with D-DAB as the diamino acid; MK-13, MK-12, and MK-14 as the respiratory quinones; ai-C15:0, ai-C17:0, and i-C16:0 as the major cellular fatty acids; and diphosphatidylglycerol, phatidylglycerol, and glycolipids as the predominant polar lipids. Strain 5GH26-15T had a B2β type peptidoglycan structure with D-DAB as the diamino acid; MK-14 and MK-13 as the respiratory quinones; ai-C15:0, i-C16:0, and ai-C{vn17:0} as the major cellular fatty acids; and diphosphatidylglycerol, phatidylglycerol, and glycolipids as the predominant polar lipids. Both strains had low DNA-DNA hybridization values (gen. nov., sp. nov. (type strain KIS66-7(T)=KACC 15515(T)=NBRC 108724(T)) and Homoserinibacter gongjuensis gen. nov., sp. nov.

    The Hybrid Electric Vehicle (HEV) program officially began in 1993 as a five-year, cost-shared partnership between the U.S. Department of Energy (DOE) and American auto manufacturers: General Motors, Ford, and Daimler Chrysler. Currently, HEV research and development is conducted by DOE through its FreedomCAR and Vehicle Technologies (FCVT) program. The mission of the FCVT program is to develop more energy efficient and environmentally friendly highway transportation technologies. Program activities include research, development, demonstration, testing, technology validation, and technology transfer. These activities are aimed at developing technologies that can be domestically produced in a clean and cost-competitive manner. The vehicle systems technologies subprogram, which is one of four subprograms under the FCVT program, supports the efforts of the FreedomCAR through a three-phase approach [1] intended to: (1) Identify overall propulsion and vehicle-related needs by analyzing programmatic goals and reviewing industry's recommendations and requirements, then develop the appropriate technical targets for systems, subsystems, and component research and development activities; (2) Develop and validate individual subsystems and components, including electric motors, emission control devices, battery systems, power electronics, accessories, and devices to reduce parasitic losses; and (3) Determine how well the components and subassemblies work together in a vehicle environment or as a complete propulsion system and whether the efficiency and performance targets at the vehicle level have been achieved. The research performed under the vehicle systems subprogram will help remove technical and cost barriers to enable technology for use in such advanced vehicles as hybrid electric, plug-in electric, and fuel-cell-powered vehicles.

    Within the LDRD on 'Critical Issues on Materials for Gen-IV Reactors' basic thermodynamics of the Fe-Cr alloy and accurate atomistic modeling were used to help develop the capability to predict hardening, swelling and embrittlement using the paradigm of Multiscale Materials Modeling. Approaches at atomistic and mesoscale levels were linked to build-up the first steps in an integrated modeling platform that seeks to relate in a near-term effort dislocation dynamics to polycrystal plasticity. The requirements originated in the reactor systems under consideration today for future sources of nuclear energy. These requirements are beyond the present day performance of nuclear materials and calls for the development of new, high temperature, radiation resistant materials. Fe-Cr alloys with 9-12% Cr content are the base matrix of advanced ferritic/martensitic (FM) steels envisaged as fuel cladding and structural components of Gen-IV reactors. Predictive tools are needed to calculate structural and mechanical properties of these steels. This project represents a contribution in that direction. The synergy between the continuous progress of parallel computing and the spectacular advances in the theoretical framework that describes materials have lead to a significant advance in our comprehension of materials properties and their mechanical behavior. We took this progress to our advantage and within this LDRD were able to provide a detailed physical understanding of iron-chromium alloys microstructural behavior. By combining ab-initio simulations, many-body interatomic potential development, and mesoscale dislocation dynamics we were able to describe their microstructure evolution. For the first time in the case of Fe-Cr alloys, atomistic and mesoscale were merged and the first steps taken towards incorporating ordering and precipitation effects into dislocation dynamics (DD) simulations.

    We report ab initio calculations of electronic and magnetic properties of medium-sized CrGen (15 ⩽ n ⩽ 29) clusters using density functional theory. The encapsulation of Cr atoms within Gen clusters leads to stable Cr encapsulated Gen clusters. The binding energies generally increase while the differences between the highest occupied molecular orbital and lowest unoccupied molecular orbital (HOMO-LUMO gaps) generally decrease with the increasing of cluster size. The clusters of CrGen at size 16, 17, 19, 22, 24 and 29 exhibit high stabilities when compared to their neighbors. This has been discussed in terms of their structures, energies and the effect of the position of doping atom. Doping of Gen clusters with one Cr atom leads to CrGen clusters with magnetic moment depending on the structure of the clusters and the position of Cr atom in the clusters. Moreover, vertical ionization potential, vertical electronic affinity, and chemical hardness are also analyzed.

Esto marcó una de las fases más importantes en el progreso de la humanidad, al permitirle transitar de una vida nómada e individualista a una sociedad organizada y cooperativista. Dicho mejoramiento fue fortuito y lento y permaneció como un arte y no como una ciencia hasta principios del siglo XX, luego de que las llamadas leyes de Mendel, pioneras en la explicación de los procesos de la herencia, obtuvieron reconocimiento (Briggs y Knowles, 1967.

    A novel halophilic, filamentous actinomycete strain, designated AFM 10258T, was isolated from a sediment sample collected from Dead Sea of Israel. The isolate grew with 10-35% NaCl and did not grow without NaCl. The isolate formed white aerial mycelium and long spore chains, and two spores were separated by sterile mycelium. The spores were non-motile, spherical and rugose-surfaced. The isolate contained meso-diaminopimelic acid as the diagnostic diamino acid and galactose and arabinose as the major whole-cell sugars. The polar lipids were diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and three unknown phospholipids. Major fatty acids were anteiso-C17:0, iso-C16:0 and iso-C15:0. MK-9(H4) was the predominant menaquinone and the DNA G+C content was 62.8 mol%. 16S rRNA gene sequence analysis indicated that strain AFM 10258T shared low sequence similarity with the closely related representatives of the families Pseudonocardiaceae (below 94.47%) and Actinopolysporaceae (below 93.76%). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain AFM 10258T formed a robust clade with members of the family Actinopolysporaceae. On the basis of analysis of phenotypic, chemical and molecular characteristics, strain AFM 10258T is considered to represent a novel species of a new genus , for which the name Haloactinomyces albus gen. nov., sp. nov., is proposed. The type strain is AFM 10258T (=DSM 45977T = CGMCC 4.7115T).

  18. Cognitive insight: A systematic review.

    2017-07-01

    Cognitive insight is the ability to re-evaluate thoughts and beliefs in order to make thoughtful conclusions. It differs from clinical insight, as it focuses on more general metacognitive processes. Therefore, it could be relevant to diverse disorders and non-clinical subjects. There is a growing body of research on cognitive insight in individuals with and without psychosis. This review has summarised the current state of the art regarding this topic. We conclude that while cognitive insight in its current form seems valid for use in individuals with psychosis, it is less so for individuals without psychosis. Additionally, higher cognitive insight not always leads to better psychological functioning. For instance, higher levels of self-reflection are often associated with depressive mood. We therefore recommend the sub-components of cognitive insight to be studied separately. Also, it is unclear what position cognitive insight takes within the spectrum of metacognitive processes and how it relates to other self-related concepts that have been defined previously in literature. Combining future and past research on cognitive insight and its analogue concepts will help in the formation of a uniform definition that fits all subjects discussed here. Copyright © 2017.

    2015-05-01

    Systemic sclerosis is an orphan connective tissue disease characterized by alterations of the microvasculature, disturbances of the immune system and massive deposition of collagen and other matrix substances in the skin and internal organs. A major achievement of the recent years has been the validation of new classification criteria, allowing earlier diagnosis and earlier treatment of systemic sclerosis, before irreversible fibrosis and organ damage appeared ("window of opportunity"). Raynaud's phenomenon is usually the first sign of the disease and is considered as the main sentinel sign for the identification of very early systemic sclerosis. Systemic sclerosis is clinically heterogeneous and disease course remains unpredictable. Its prognosis depends on cardiopulmonary involvement and recent studies aim to identify serum or genetic biomarkers predictive of severe organ involvement. Moreover, the prospective follow-up of large cohorts has provided and will offer critical material to identify strong prognostic factors. Whereas the outcomes of vascular manifestations of the disease has been recently improved due to targeted therapy, recent data have highlighted that mortality has not changed over the past 40 years. This reflects the absence of efficacy of current available drugs to counteract the fibrotic process. Nevertheless, several targeted immunity therapies, commonly with proven efficacy in other immune diseases, are about to be investigated in systemic sclerosis. Indeed, promising results in small and open studies have been reported. This article deals with recent insights into classification criteria, pathogenesis, organ involvements, outcome and current and possible future therapeutic options in systemic sclerosis.

Foram instalados testes de germinação em delineamento inteiramente ao acaso, no esquema fatorial 8 x 2 (genótipos: CCN51, PH16, CEPEC2002, Ipiranga, SJ02, PS1319, TSH1188 e Comum x dois períodos de armazenamento: 0 e dois dias. O genótipo TSH1188 apresentou maior comprimento, relação comprimento/largura, espessura e massa de 100 sementes. A absorção de água das sementes recém-colhidas dos genótipos é lenta, justificada pelos altos teores de água, o que não caracteriza padrão-trifásico. Os teores de água reduziram em média 2,3 vezes nas sementes armazenadas em relação às recém-colhidas. A germinação das sementes recém-colhidas dos genótipos foi de 100%. Após o armazenamento, as sementes do PS1319 apresentaram a menor redução da germinação (39%, enquanto as dos PH16, CEPEC2002 e SJ02 reduziram 96%. A velocidade de germinação foi maior e o tempo médio menor que dois dias nas sementes recém-colhidas do PS1319, indicando serem mais tolerante à dessecação.

  2. ATLAS Versus NextGen Model Atmospheres: A Combined Analysis of Synthetic Spectral Energy Distributions

    Bertone, E.; Buzzoni, A.; Chávez, M.; Rodríguez-Merino, L. H.

    2004-08-01

    We carried out a critical appraisal of the two theoretical models, Kurucz' ATLAS9 and PHOENIX/NextGen, for stellar atmosphere synthesis. Our tests relied on the theoretical fit of spectral energy distributions (SEDs) for a sample of 334 target stars along the whole spectral-type sequence, from the classical optical catalogs of Gunn & Stryker and Jacoby et al. The best-fitting physical parameters (Teff, logg) of stars allowed an independent calibration of the temperature and bolometric scale versus empirical classification parameters (i.e., spectral type and MK luminosity class); in addition, the comparison of the synthetic templates from the ATLAS and NextGen grids allowed us to probe the capability of the models to match spectrophotometric properties of real stars and assess the impact of the different input physics. We can sketch the following main conclusions of our analysis: (1) Fitting accuracy of both theoretical libraries drastically degrades at low Teff at which both ATLAS and NextGen models still fail to properly account for the contribution of molecular features in the observed SED of K-M stars. (2) Compared with empirical calibrations, both ATLAS and NextGen fits tend, on average, to predict slightly warmer (by 4%-8%) Teff for both giant and dwarf stars of fixed spectral type, but ATLAS provides, in general, a sensibly better fit (a factor of 2 lower σ of flux residuals) than NextGen. (3) There is a striking tendency of NextGen to label target stars with an effective temperature and surface gravity higher than that of ATLAS. The effect is especially evident for MK I-III objects for which about one in four stars is clearly misclassified by NextGen in logg. This is a consequence of some ``degeneracy'' in the solution space, partly induced by the different input physics and geometry constraints in the computation of the integrated emerging flux (ATLAS model atmospheres assume standard plane-parallel layers, while NextGen adopts, for low-gravity stars, a

    Full Text Available La diversidad biológica, su conservación e incremento, es uno de los principios básicos de la gestión forestal sostenible. La alta variabilidad genética de las especies forestales es responsable de los procesos de adaptación ante factores bióticos y abióticos extremos que, a su vez, aseguran la persistencia frente a los riesgos a los que están sometidas las masas forestales. En este trabajo se analizan distintos aspectos relacionados con la variabilidad genética de las especies forestales, y como la gestión forestal influye sobre ella. Se analiza la variabilidad entre poblaciones (que es una de las bases de la comercialización de material forestal de reproducción, la influencia del sistema de reproducción en la variabilidad genética de las masas y los efectos en ellas de los tratamientos selvícolas, así como la variación individual y clonal aprovechada en los programas de selección. Por último, se analiza el papel de la variabilidad genética en los programas de mejora y conservación de recursos genéticos forestales

    Full Text Available Abstract Background The integration of genomic information with quantitative experimental data is a key component of systems biology. An increasing number of microbial genomes are being sequenced, leading to an increasing amount of data from post-genomics technologies. The genomes of prokaryotes contain many structures of interest, such as operons, pathogenicity islands and prophage sequences, whose behaviour is of interest during infection and disease. There is a need for simple and novel tools to display and analyse data from these integrated datasets, and we have developed ProGenExpress as a tool for visualising arbitrarily complex numerical data in the context of prokaryotic genomes. Results Here we describe ProGenExpress, an R package that allows researchers to easily and quickly visualize quantitative measurements, such as those produced by microarray experiments, in the context of the genome organization of sequenced prokaryotes. Data from microarrays, proteomics or other whole-genome technologies can be accurately displayed on the genome. ProGenExpress can also search for novel regions of interest that consist of groups of adjacent genes that show similar patterns across the experimental data set. We demonstrate ProGenExpress with microarray data from a time-course experiment involving Salmonella typhimurium. Conclusion ProGenExpress can be used to visualize quantitative data from complex experiments in the context of the genome of sequenced prokaryotes, and to find novel regions of interest.

    Holliday junction (HJ) resolution is essential for chromosome segregation at meiosis and the repair of stalled/collapsed replication forks in mitotic cells. All organisms possess nucleases that promote HJ resolution by the introduction of symmetrically related nicks in two strands at, or close to, the junction point. GEN1, a member of the Rad2/XPG nuclease family, was isolated recently from human cells and shown to promote HJ resolution in vitro and in vivo. Here, we provide the first biochemical/structural characterization of GEN1, showing that, like the Escherichia coli HJ resolvase RuvC, it binds specifically to HJs and resolves them by a dual incision mechanism in which nicks are introduced in the pair of continuous (noncrossing) strands within the lifetime of the GEN1-HJ complex. In contrast to RuvC, but like other Rad2/XPG family members such as FEN1, GEN1 is a monomeric 5'-flap endonuclease. However, the unique feature of GEN1 that distinguishes it from other Rad2/XPG nucleases is its ability to dimerize on HJs. This functional adaptation provides the two symmetrically aligned active sites required for HJ resolution.

    Full Text Available El autismo, hoy en día definido como trastornos del espectro autista, fue descrito inicialmente en 1943. Se caracteriza por alteraciones en la comunicación, la interacción social y un espectro restringido de intereses del paciente. Generalmente se identifica en etapas tempranas del desarrollo a partir de los 18 meses de edad. Actualmente el autismo se considera un desorden neurológico con un espectro que abarca diferentes grados que se asocian con factores genéticos, no genéticos y del medio ambiente. Dentro de los factores genéticos se han referido diversos síndromes relacionados con este trastorno. Asimismo, el autismo se ha estudiado a nivel genético, neurofisiológico, neuroquímico y neuropatológico. Las técnicas de neuroimagen han mostrado múltiples anormalidades estructurales en estos pacientes. También se han observado alteraciones relacionadas en los sistemas serotoninérgico, GABAérgico, catecolaminérgico y colinérgico. En este trabajo se presenta una actualización de la información de los aspectos genéticos y neuroendocrinos del trastorno del espectro autista.

    Full Text Available Apolitical sociology of food must look into the processes whereby regulatory decisions on food are made, and also into the democratic potential of their alternatives. Five "experiments in democracy" are described, in which a promising deliberative device has been used: citizens' juries. Indian and Brazilian peasants, on the one hand, and British consumers in the other took part in them, and they focused on Genetically Modified Organisms. These processes, whose defining trait is granting jurors access to expert witnesses presented by all stakeholders in the controversy, show the impressive ability of ordinary citizens to articulate their analysis of complex issues, a reassessment of risks, and a recontextualization of the use of GMOs. At any rate, deliberative democracy is not a magic bullet for the epistemic and political crisis that underlies food crisis; instead, it points at a paradigm change towards an experimental democratic polity in which the instances of representation of the public and publics are multiplied.

    Una sociología política de la alimentación debe analizar los procesos a través de los cuales se alcanzan las decisiones de regulación y control alimentario y examinar el potencial de sus alternativas. Se describen aquí cinco experimentos democráticos en los que se ha empleado uno de los dispositivos deliberativos más prometedores en condiciones de alta complejidad cognitiva, los llamados jurados ciudadanos, con la participación de campesinos hindúes y brasileños y consumidores británicos, y centrados en los Organismos Genéticamente Modificados. Estos procesos, caracterizados por el acceso de los miembros del jurado a testigos expertos presentados por los distintos participantes en la controversia, muestran la enorme capacidad de los ciudadanos "de a pie" para articular el análisis de un problema complejo, reevaluar sus riesgos y recontextualizar el uso de los OGM.

    A Gram-stain-negative, non-spore-forming and coccus-shaped bacterial strain, designated 4DR5T, was isolated from freshwater and its taxonomic position was investigated using a polyphasic approach. Growth occurred at 10-40 °C (optimum 30 °C), at pH 6-9 (optimum pH 7) and in the presence of 0-0.4 % (w/v) NaCl (optimum 0 %) on R2A agar. On the basis of 16S rRNA gene sequence similarity, strain 4DR5T was assigned to the family Moraxellaceae of the class Gammaproteobacteria, and its closest related taxa were species of the genera Perlucidibaca (93.67 % sequence similarity), Agitococcus (93.07 %), Paraperlucidibaca (92.31-92.38 %), Alkanindiges (91.79 %) and Acinetobacter (90.24-91.23 %). The predominant isoprenoid quinone detected in strain 4DR5T was Q-10. The major cellular fatty acids were a summed feature consisting of C16 : 1ω7c and/or C16 : 1ω6c, one consisting of C18 : 1ω7c and/or C18 : 1ω6c, and C16 : 0. The major polar lipid was phosphatidylethanolamine. The genomic DNA G+C content of the strain was 61.2 mol%. The phylogenetic, chemotaxonomic and biochemical data not only supported the affiliation of strain 4DR5T to the family Moraxellaceae, but also separated it from other established genera within the family. Therefore, the novel isolate evidently represents a novel species of a new genus of Moraxellaceae, for which the name Fluviicoccus keumensis gen. nov., sp. nov. is proposed. The type strain of Fluviicoccus keumensis is 4DR5T ( = KCTC 32475T = JCM 19370T).

    With a goal to produce magnetic moment in Cr2 Doped Gen clusters which will be useful for practical applications, we have considered the structure and magnetic properties of Pure Germanium clusters and substitutionally doped it with Cr dimer to produce Cr2@Gen clusters. As the first step of calculation, geometrical optimizations of the nanoclusters have been done. These optimized geometries have been used in calculate the average binding energy per atom (BE), HOMO-LUMO gap and hence the relative stability of the clusters. These parameters have been demonstrated as structural and electronic properties of the clusters. Gap between highest occupied molecular orbital and lowest unoccupied molecular orbital indicate cluster to be a potential motif for generating magnetic cluster assembled materials. Based on these values a comparative study on different sized clusters has been done in order to understand the origin of structures, electronic and magnetic properties of Cr2@Gen nanoclusters.

    Barbara Kanki from NASA Ames Research Center will discuss research that focuses on the collaborations between pilots, air traffic controllers and dispatchers that will change in NextGen systems as automation increases and roles and responsibilities change. The approach taken by this NASA Ames team is to build a collaborative systems assessment template (CSAT) based on detailed task descriptions within each system to establish a baseline of the current operations. The collaborative content and context are delineated through the review of regulatory and advisory materials, policies, procedures and documented practices as augmented by field observations and interviews. The CSAT is developed to aid the assessment of key human factors and performance tradeoffs that result from considering different collaborative arrangements under NextGen system changes. In theory, the CSAT product may be applied to any NextGen application (such as Trajectory Based Operations) with specified ground and aircraft capabilities.

    The present study is aimed at investigating the impact of mentoring on intention to stay of Gen Y employees working in Indian IT industry. Also, the mediating roles of perceived organization support and affective commitment are examined. Primary data were collected from a sample of 314 Gen Y employees (born between 1980-2000) from IT industry in Delhi, NCR India. Data analysis was carried out using AMOS and SPSS to test sequential mediation. Findings reveal that mentoring has a direct influence on intention to stay of Gen Y employees and perceived organization support and affective commitment sequentially mediate the relationship between the two. This study contributes to the literature on mentoring, perceived organization support, affective commitment, and intention to stay. PMID:28580029

    2007-08-01

    Full Text Available Abstract Background Detection of short, subtle conserved motif regions within a set of related DNA or amino acid sequences can lead to discoveries about important regulatory domains such as transcription factor and DNA binding sites as well as conserved protein domains. In order to help assess motif detection algorithms on motifs with varying properties and levels of conservation, we have developed a computational tool, rMotifGen, with the sole purpose of generating a number of random DNA or protein sequences containing short sequence motifs. Each motif consensus can be user-defined, randomly generated, or created from a position-specific scoring matrix (PSSM. Insertions and mutations within these motifs are created according to user-defined parameters and substitution matrices. The resulting sequences can be helpful in mutational simulations and in testing the limits of motif detection algorithms. Results Two implementations of rMotifGen have been created, one providing a graphical user interface (GUI for random motif construction, and the other serving as a command line interface. The second implementation has the added advantages of platform independence and being able to be called in a batch mode. rMotifGen was used to construct sample sets of sequences containing DNA motifs and amino acid motifs that were then tested against the Gibbs sampler and MEME packages. Conclusion rMotifGen provides an efficient and convenient method for creating random DNA or amino acid sequences with a variable number of motifs, where the instance of each motif can be incorporated using a position-specific scoring matrix (PSSM or by creating an instance mutated from its corresponding consensus using an evolutionary model based on substitution matrices. rMotifGen is freely available at: http://bioinformatics.louisville.edu/brg/rMotifGen/.

Com o advento de informações sobre a completa seqüência de genes ao longo do genoma humano e de outros organismos, o interesse da epidemiologia genética em desvendar a natureza dos fatores que influenciam essas características se tornou primordial. São apresentados os principais métodos empregados no estudo de doenças complexas bem como suas principais vantagens e desvantagens. Discute-se a importância na determinação da amostra e o uso de fenótipos e marcadores genéticos apropriados. Como exemplo das estratégias citadas tomamos o estudo de índice de massa corporal (BMI para ilustrar um fator genético principal localizado no cromossomo 7. Em uma discussão sobre tendências no estudo de ligação, embora reconhecendo que famílias e genealogias continuarão sendo o foco principal das amostras, discute-se alguns novos e eficientes tipos de amostragem (como por exemplo, controles não-relacionados em que amostras de conjunto de DNA serão universalmente empregadas. O reconhecimento da heterogeneidade genética entre estudos e sua interpretação será uma das mais importantes características no futuro das análises de características complexas.

  3. SIPSMetGen: It's Not Just For Aircraft Data and ECS Anymore.

    Schwab, M.

    2015-12-01

    The SIPSMetGen utility, developed for the NASA EOSDIS project, under the EED contract, simplified the creation of file level metadata for the ECS System. The utility has been enhanced for ease of use, efficiency, speed and increased flexibility. The SIPSMetGen utility was originally created as a means of generating file level spatial metadata for Operation IceBridge. The first version created only ODL metadata, specific for ingest into ECS. The core strength of the utility was, and continues to be, its ability to take complex shapes and patterns of data collection point clouds from aircraft flights and simplify them to a relatively simple concave hull geo-polygon. It has been found to be a useful and easy to use tool for creating file level metadata for many other missions, both aircraft and satellite. While the original version was useful it had its limitations. In 2014 Raytheon was tasked to make enhancements to SIPSMetGen, this resulted a new version of SIPSMetGen which can create ISO Compliant XML metadata; provides optimization and streamlining of the algorithm for creating the spatial metadata; a quicker runtime with more consistent results; a utility that can be configured to run multi-threaded on systems with multiple processors. The utility comes with a java based graphical user interface to aid in configuration and running of the utility. The enhanced SIPSMetGen allows more diverse data sets to be archived with file level metadata. The advantage of archiving data with file level metadata is that it makes it easier for data users, and scientists to find relevant data. File level metadata unlocks the power of existing archives and metadata repositories such as ECS and CMR and search and discovery utilities like Reverb and Earth Data Search. Current missions now using SIPSMetGen include: Aquarius, Measures, ARISE, and Nimbus.

In this context, we developed the LabSystem Gen tool that allows users to create a Laboratory Information System, without programming. Additionally we implemented a framework that provides bioinformatic tools, transparent access to public HLA (human leukocyte antigen) information resources. We demonstrated the LabSystemGen system by implementing BMDdb, which is a LIMS that manages data of recipients and donors of organ transplant.

  15. Biochemical and molecular characterization of the gentisate transporter GenK in Corynebacterium glutamicum.

    Directory of Open Access Journals (Sweden)

    Ying Xu

    Full Text Available BACKGROUND: Gentisate (2,5-dihydroxybenzoate is a key ring-cleavage substrate involved in various aromatic compounds degradation. Corynebacterium glutamicum ATCC13032 is capable of growing on gentisate and genK was proposed to encode a transporter involved in this utilization by its disruption in the restriction-deficient mutant RES167. Its biochemical characterization by uptake assay using [(14C]-labeled gentisate has not been previously reported. METHODOLOGY/PRINCIPAL FINDINGS: In this study, biochemical characterization of GenK by uptake assays with [(14C]-labeled substrates demonstrated that it specifically transported gentisate into the cells with V(max and K(m of 3.06 ± 0.16 nmol/min/mg of dry weight and 10.71 ± 0.11 µM respectively, and no activity was detected for either benzoate or 3-hydoxybenzoate. When GenK was absent in strain RES167 ΔgenK, it retained 85% of its original transport activity at pH 6.5 compared to that of strain RES167. However, it lost 79% and 88% activity at pH 7.5 and 8.0, respectively. A number of competing substrates, including 3-hydroxybenzoate, benzoate, protocatechuate and catechol, significantly inhibited gentisate uptake by more than 40%. Through site-directed mutagenesis, eight amino acid residues of GenK, Asp-54, Asp-57 and Arg-386 in the hydrophobic transmembrane regions and Arg-103, Trp-309, Asp-312, Arg-313 and Ile-317 in the hydrophilic cytoplasmic loops were shown to be important for gentisate transport. When conserved residues Asp-54 and Asp-57 respectively were changed to glutamate, both mutants retained approximately 50% activity and were able to partially complement the ability of strain RES167 ΔgenK to grow on gentisate. CONCLUSIONS/SIGNIFICANCE: Our results demonstrate that GenK is an active gentisate transporter in Corynebacterium glutamicum ATCC13032. The GenK-mediated gentisate transport was also shown to be a limiting step for the gentisate utilization by this strain. This enhances our

A través de diferentes técnicas de análisis (escalamiento multidimensional, correlación y correlación parcial de matrices se puso a prueba si las distancias genéticas reflejaban las relaciones interpoblacionales esperadas a partir de la distribución geográfica o de relaciones lingüísticas entre las poblaciones. Además, se estimó en que grado las distintas medidas de distancias genéticas eran influenciadas por la diversidad (He de cada población. Los mapas genéticos muestran, principalmente para DST y DA, que las poblaciones aisladas y con bajo tamaño efectivo (Ne aparecen como outliers, mientras que las poblaciones con alto Ne y mayor flujo génico ocupan una posición central a bajos valores de distancia unas de otras y sin un patrón definido de agrupamiento. La falta de asociación entre distancias genéticas y lingüísticas o geográficas y por otra parte, la alta correlación negativa entre He y distancias génicas promedio por población confiman ese patrón, demostrando que la mayor parte de la variación interpoblacional puede ser explicada en función del grado de diversidad intrapoblacional. Es decir, las distancias genéticas no reflejan relaciones filogenéticas, lingüísticas o geográficas, sino más bien eventos demográficos recientes tales como cuellos de botella genético, efecto fundador o migración externa masiva. Este hecho puede ser comprobado por medio de otra metodología analítica, el modelo de Harpending y Ward.

    2014-01-01

    Earlier phylogenetic analyses of the marine Rhodobacteraceae (class Alphaproteobacteria) genera Leisingera and Phaeobacter indicated that neither genus might be monophyletic. We here used phylogenetic reconstruction from genome-scale data, MALDI-TOF mass-spectrometry analysis and a re-assessment of the phenotypic data from the literature to settle this matter, aiming at a reclassification of the two genera. Neither Phaeobacter nor Leisingera formed a clade in any of the phylogenetic analyses conducted. Rather, smaller monophyletic assemblages emerged, which were phenotypically more homogeneous, too. We thus propose the reclassification of Leisingera nanhaiensis as the type species of a new genus as Sedimentitalea nanhaiensis gen. nov., comb. nov., the reclassification of Phaeobacter arcticus and Phaeobacter leonis as Pseudophaeobacter arcticus gen. nov., comb. nov. and Pseudophaeobacter leonis comb. nov., and the reclassification of Phaeobacter aquaemixtae, Phaeobacter caeruleus, and Phaeobacter daeponensis as Leisingera aquaemixtae comb. nov., Leisingera caerulea comb. nov., and Leisingera daeponensis comb. nov. The genera Phaeobacter and Leisingera are accordingly emended.

    Full Text Available The increasing demand for raw material for multiple uses of forest products and by-products has attracted the interest for fast growing species, such as the Australian Cedar (Toona ciliata, which presents high productive and economic potential. The present work aimed at estimating genetic diversity by DNA markers and morphological traits supported for the mixed models. The following traits were measured and genotypes were sampled randomly in different areas: diameter at breast height, height, cylindrical volume, diameter, distance between nodes and crown diameter. Twelve RAPD primers were used and generated a total of 91 marks, 82 of which were polymorphic. The high percentage of polymorphic markers, 90.10%, demonstrated that discrimination in this species is efficient, but it yet little studied, for this case we can find the extent of the genetic basis for the application of technical improvement. The assessment of genetic diversity by the UPGMA method using the binary and morphological data provided the expression of genetic dissimilarities among the accessions evaluated, optimizing the perception of this divergence. The use of mixed models was efficient to assess combined genetic diversity to optimize the selection of genotypes with divergent genetic values for diameter at breast height.A crescente demanda por matéria-prima para múltiplos usos dos produtos florestais e subprodutos tem despertado o interesse para espécies de crescimento rápido, como o cedro australiano (Toona ciliata, que apresenta potencial produtivo e econômico.

    The taxonomic position of three novel sea-water isolates was determined. The strains studied were strictly aerobic, heterotrophic, pigmented, motile by gliding, Gram-negative and oxidase-, catalase-, beta-galactosidase- and alkaline phosphatase-positive. 16S rRNA gene sequence phylogenetic analysis indicated that the strains KMM 6020T, KMM 6021 and KMM 6028 occupied a distinct lineage within the family Flavobacteriaceae. The major respiratory quinone was MK-6. The predominant fatty acids were i15 : 0, i15 : 1, i15 : 0 3-OH, i17 : 1omega9c and i17 : 0 3-OH. On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the novel bacteria were assigned to the genus Aquimarina gen. nov., as Aquimarina muelleri gen. nov., sp. nov. The type strain is KMM 6020T (=KCTC 12285T=LMG 22569T). From the results of the 16S rRNA gene sequence analysis and phenotypic features, the species [Cytophaga] latercula Lewin 1969 is proposed to be reclassified in the new genus Stanierella as Stanierella latercula gen. nov., comb. nov., with type strain CIP 104806T (=ATCC 23177T=NCIMB 1399T=LMG 1343T).

Se plantea que el mismo conocimiento genético imposibilita la asunción de estas posiciones radicales, razón por la cual la investigación biológica actúa con cautela en la formulación de hipótesis causales. No obstante, se pone de manifiesto la interpretación inapropiada de los resultados de investigaciones genéticas y biológicas, cuando por un lado, se postula la complejidad del fenómeno, pero por otro lado y por un acto de simplificación cognoscitiva, se desatiende esa complejidad y se da el salto hacia explicaciones monocausales. La actividad investigativa en el campo de la esquizofrenia se enfrenta entonces a la responsabilidad histórica de dar a cada elemento el lugar que le corresponde en la intrincada red de elementos que influyen en la aparición y desarrollo de la esquizofrenia.

  4. Chitinozoan faunas from the Rügen Ordovician (Rügen 5/66 and Binz 1/73 wells), NE Germany.

    The island of Rügen (NE Germany), situated close to the Trans-European Suture Zone (TESZ), in the southern Baltic Sea is underlain by sedimentary rocks of an Early Palaeozoic age, known only from boreholes. The wells, Rügen 5/66 and Binz 1/73, were investigated for their chitinozoan assemblages to improve the earlier biostratigraphic dating (graptolites and acritarchs) and to facilitate comparisons with other chitinozoan assemblages on both sides of the TESZ. In the lower part of the Rügen 5/66 core (3794.7-3615.8m), Lagenochitina destombesi Elaouad-Debbaj is indicative of an early late Tremadoc age. In the upper part of the same well (3287.3-1709.7m), the observed chitinozoan taxa suggest an age spanning the early Llanvirn to the Caradoc. The entire sampled interval of the Binz 1/73 core (5217.6-5041.8m) is interpreted as belonging to the Siphonochitina formosa Biozone (early-early late Abereiddian, corresponding to the early Llanvirn). The chitinozoan data corroborate the earlier suggested biostratigraphic ages, based on acritarchs and graptolites. The chitinozoans from the Binz 1/73 well point to a high latitude provenance of the investigated host sediments at time of deposition.

    Full Text Available OBJETIVO: Apresentar os resultados dos estudos mais importantes e recentes sobre a genética da asma. Estes dados devem auxiliar os clínicos gerais a compreender o impacto da genética sobre este distúrbio complexo e como os genes e polimorfismos influenciam a asma e a atopia. FONTES DOS DADOS: Os dados foram coletados do banco de dados MEDLINE. Os estudos de associação genética foram selecionados do Genetic Association Database, um repositório de estudos de associação genética de doenças e distúrbios complexos organizado pelo National Institutes of Health. SÍNTESE DOS DADOS: Considerando os dados de diversos importantes estudos de gêmeos sobre a genética da asma, a heritabilidade, que mensura a contribuição dos fatores genéticos para a variância da asma, pode ser estimada entre 0,48 e 0,79. Uma grande quantidade de estudos de associação genética tentou identificar genes de susceptibilidade à asma. Os resultados mais replicados nos estudos de associação genética envolvem as cinco regiões do genoma humano a seguir: 5q31-32, 6p21, 11q12-13, 16p11-12, e 20p13. Recentemente, outro gene de susceptibilidade à asma (ORMDL3, considerado determinante crítico para a asma infantil, foi identificado por um estudo genômico de associação. CONCLUSÕES: É possível estimar que a contribuição genética à asma varia entre 48 e 79%. Diversos loci parecem influenciar a susceptibilidade à asma. Os genes localizados no cromossomo 5q (ADRB2, IL13 e IL4 e o gene ORMDL3, no cromossomo 17, identificado recentemente, parecem ser determinantes para a asma infantil.

    Full Text Available With the development of new cultivars, a precise genetic characterization is essential for improvement programs or for cultivar registration and protection. Molecular markers have been complementing the traditional morphological and agronomic characterization techniques because they are virtually unlimited, cover the whole genome and are not environmentally influenced. Genetic characterization constitutes the basis for studies involving estimates of genetic similarity. Therefore, the objective of the present study was to evaluate the genetic similarity between ten coriander genotypes (nine cultivars and one line using ISSR markers. The cultivars used were: Americano, Asteca, Palmeira, Português, Santo, Supéria, Tabocas, Tapacurá, Verdão and the experimental line HTV-9299. The genetic similarity between the cultivars was estimated using 227 banded regions of ISSR molecular markers. The UBC 897 oligonucleotide generated the highest number of fragments (16, resulting in a higher polymorphism. The results indicate that the twenty-nine oligonucleotides chosen were satisfactory for detecting polymorphism. Based on the grouping analysis determined from the similarity data, there were two groups and two sub-groups. The calculated similarity for the genotypes varied from 52 to 75%. The lowest similarity was observed between Português and Verdão, at 52%. The highest similarity was found between Português and Palmeira, at 75%. The ISSR is efficient for identifying DNA polymorphism in coriander.Com o surgimento de novas cultivares, uma caracterização genética precisa é essencial, visando à utilização em programas de melhoramento ou para fins de registros e ou proteção de cultivares.

    Next-gen sequencing technologies have revolutionized data collection in genetic studies and advanced genome biology to novel frontiers. However, to date, next-gen technologies have been used principally for whole genome sequencing and transcriptome sequencing. Yet many questions in population genetics and systematics rely on sequencing specific genes of known function or diversity levels. Here, we describe a targeted amplicon sequencing (TAS) approach capitalizing on next-gen capacity to sequence large numbers of targeted gene regions from a large number of samples. Our TAS approach is easily scalable, simple in execution, neither time-nor labor-intensive, relatively inexpensive, and can be applied to a broad diversity of organisms and/or genes. Our TAS approach includes a bioinformatic application, BarcodeCrucher, to take raw next-gen sequence reads and perform quality control checks and convert the data into FASTA format organized by gene and sample, ready for phylogenetic analyses. We demonstrate our approach by sequencing targeted genes of known phylogenetic utility to estimate a phylogeny for the Pancrustacea. We generated data from 44 taxa using 68 different 10-bp multiplexing identifiers. The overall quality of data produced was robust and was informative for phylogeny estimation. The potential for this method to produce copious amounts of data from a single 454 plate (e.g., 325 taxa for 24 loci) significantly reduces sequencing expenses incurred from traditional Sanger sequencing. We further discuss the advantages and disadvantages of this method, while offering suggestions to enhance the approach.

    Full Text Available On sait très peu sur la pensée politique de Félicité de Genlis (1746-1830 à part le fait qu’elle est devenue royaliste après la Révolution française. Cependant le tableau de l’Arcadie de Lagaraye dans Adèle et Théodore, ou lettres sur l’éducation (1782, fournit beaucoup de détails sur ce sujet. La figure du Législateur, en particulier, y démontre que la pensée politique de Genlis s’intéresse principalement à l’administration émotive des sociétés politiques, surtout en ce qui regarde les femmes, tout en rappelant – et en critiquant – les préoccupations politiques de Jean-Jacques Rousseau. Cet article analyse les correspondances et les contrastes entre Lagaraye et l’Arcadie de Clarens que Rousseau a dépeint dans Julie, ou la nouvelle Héloïse (1762. Il met Genlis en avant comme une critique sévère des idées de Rousseau, ainsi qu’une adhérente secrète du rousseauisme politique qui a développé sa vision politique sur la base de celle du Citoyen de Genève.

    The Chinese drug "Shan-Dou-Gen" has been used for removing toxic heat, promoting the subsidence of swelling and soothing the sore throat since the ancient time. The authors made a survey of the drug "Shan-Dou-Gen" available in drug markets as well as the plant origin from the drug producing districts. The results showed that the drug "Shan-Dou-Gen" used in different regions in China at present are the roots or rhizomes derived from 9 species: Sophora tonkinensis Gagnep. (Leguminosae), Menispermum dauricum DC. (Menispermaceae), Indigofera amblyantha Craib (Leguminosae), I. carlesii Carib, I., fortunei Craib, I. decoa Lindl. var. ichangensis Y. Y. Fang et C. Z. Zheng, I. kirilowii Maxim. et Palibin, I. potaninii Craib, and Beesia calthaefolia (Maxim.) Ulbr. (Ranuculaceae). In this paper, the morphological characters of the crude drugs are described, compared and illustrated with photographs. The histological structures of the used parts are described, compared and illustrated with line drawings. The morphological and histological similarities and differences found among the above 9 species are summarized, and the key for the identification of the crude drugs is provided. As the drug "Shan-Dou-Gen" derived from different species has different actions and dosages, it is necessary to give different names to different species and use them correctly.

    Full Text Available Très peu de philosophes politiques se sont intéressés à l’oeuvre de Genlis, en partie parce que son oeuvre est communément réduite à un moralisme religieux insipide. Si Alice Laborde con-clut sa biographie en soulignant que Genlis « est moraliste avant tout », les travaux récents de Mary Trouille mettent tout autant l’accent sur le fait que la comtesse est « moralist to the core ». La visée du présent article est de nuancer cette lecture, non pas en niant le moralisme de Genlis, mais plutôt en montrant que celui-ci ne l’a pas empêchée de publier des textes à portée politique qui mériteraient notre attention aujourd’hui—particulièrement l’attention de ceux et celles qui se donnent pour tâche de penser l’accueil et le soin de l’Autre.

    With the continuous improvement in genotyping and molecular phenotyping technology and the decreasing typing cost, it is expected that in a few years, more and more clinical studies of complex diseases will recruit thousands of individuals for pan-omic genetic association analyses. Hence, there is a great need for algorithms and software tools that could scale up to the whole omic level, integrate different omic data, leverage rich structure information, and be easily accessible to non-technical users. We present GenAMap, an interactive analytics software platform that 1) automates the execution of principled machine learning methods that detect genome- and phenome-wide associations among genotypes, gene expression data, and clinical or other macroscopic traits, and 2) provides new visualization tools specifically designed to aid in the exploration of association mapping results. Algorithmically, GenAMap is based on a new paradigm for GWAS and PheWAS analysis, termed structured association mapping, which leverages various structures in the omic data. We demonstrate the function of GenAMap via a case study of the Brem and Kruglyak yeast dataset, and then apply it on a comprehensive eQTL analysis of the NIH heterogeneous stock mice dataset and report some interesting findings. GenAMap is available from http://sailing.cs.cmu.edu/genamap.

    The objective of the FutureGen 2.0 Project was to demonstrate, at the commercial scale, the technical feasibility of implementing carbon capture and storage (CCS) in a deep saline formation in Illinois, USA. Over approximately 5 years, the FutureGen Alliance conducted a detailed site-selection process and identified a site for carbon sequestration storage in Morgan County, Illinois. The storage site was fully characterized, including the collection of seismic data and the drilling and characterization of a stratigraphic borehole. The characterization data provided critical input for developing a site-specific conceptual model and subsequent numerical modeling simulations. The modeling simulations, coupled with the upstream designs of the pipeline and power plant supported the development of a detailed 90 percent design that included the injection wells and associated control and monitoring infrastructure. Collectively, all these data were used by the FutureGen Alliance to develop the required documentation to support the applications for four underground injection control (UIC) permits (one for each proposed well). In August 2014, the U.S. Environmental Protection Agency issued four, first-of-their-kind, Class VI UIC permits for carbon sequestration in the United States to the FutureGen Alliance. The information and data generated under this project have been made publically available through reports and publications, including this journal and others.

  8. GEN1 promotes Holliday junction resolution by a coordinated nick and counter-nick mechanism.

    Science.gov (United States)

    Chan, Ying Wai; West, Stephen

    2015-12-15

    Holliday junctions (HJs) that physically link sister chromatids or homologous chromosomes are formed as intermediates during DNA repair by homologous recombination. Persistent recombination intermediates are acted upon by structure-selective endonucleases that are required for proper chromosome segregation at mitosis. Here, we have purified full-length human GEN1 protein and show that it promotes Holliday junction resolution by a mechanism that is analogous to that exhibited by the prototypic HJ resolvase E. coli RuvC. We find that GEN1 cleaves HJs by a nick and counter-nick mechanism involving dual co-ordinated incisions that lead to the formation of ligatable nicked duplex products. As observed with RuvC, cleavage of the first strand is rate limiting, while second strand cleavage is rapid. In contrast to RuvC, however, GEN1 is largely monomeric in solution, but dimerizes on the HJ. Using HJs containing non-cleavable phosphorothioate-containing linkages in one strand, we show that the two incisions can be uncoupled and that the first nick occurs upon GEN1 dimerization at the junction. These results indicate that the mechanism of HJ resolution is largely conserved from bacteria to man, despite a lack of sequence homology between the resolvases. © The Author(s) 2015.

    Full Text Available Automatically detecting gene/protein names in the literature and connecting them to databases records, also known as gene normalization, provides a means to structure the information buried in free-text literature. Gene normalization is critical for improving the coverage of annotation in the databases, and is an essential component of many text mining systems and database curation pipelines.In this manuscript, we describe a gene normalization system specifically tailored for plant species, called pGenN (pivot-based Gene Normalization. The system consists of three steps: dictionary-based gene mention detection, species assignment, and intra species normalization. We have developed new heuristics to improve each of these phases.We evaluated the performance of pGenN on an in-house expertly annotated corpus consisting of 104 plant relevant abstracts. Our system achieved an F-value of 88.9% (Precision 90.9% and Recall 87.2% on this corpus, outperforming state-of-art systems presented in BioCreative III. We have processed over 440,000 plant-related Medline abstracts using pGenN. The gene normalization results are stored in a local database for direct query from the pGenN web interface (proteininformationresource.org/pgenn/. The annotated literature corpus is also publicly available through the PIR text mining portal (proteininformationresource.org/iprolink/.

  18. Crystal Structure of a Eukaryotic GEN1 Resolving Enzyme Bound to DNA

    2015-12-01

    Full Text Available We present the crystal structure of the junction-resolving enzyme GEN1 bound to DNA at 2.5 Å resolution. The structure of the GEN1 protein reveals it to have an elaborated FEN-XPG family fold that is modified for its role in four-way junction resolution. The functional unit in the crystal is a monomer of active GEN1 bound to the product of resolution cleavage, with an extensive DNA binding interface for both helical arms. Within the crystal lattice, a GEN1 dimer interface juxtaposes two products, whereby they can be reconnected into a four-way junction, the structure of which agrees with that determined in solution. The reconnection requires some opening of the DNA structure at the center, in agreement with permanganate probing and 2-aminopurine fluorescence. The structure shows that a relaxation of the DNA structure accompanies cleavage, suggesting how second-strand cleavage is accelerated to ensure productive resolution of the junction.

  19. Reassessment of the taxonomic structure of the diazotrophic genus Azoarcus sensu lato and description of three new genera and new species, Azovibrio restrictus gen. nov., sp. nov., Azospira oryzae gen. nov., sp. nov. and Azonexus fungiphilus gen. nov., sp. nov.

    The taxonomic structure of members of the genus Azoarcus sensu lato was reassessed in a polyphasic approach. Two species, Azoarcus communis and Azoarcus indigens, three unnamed species containing diazotrophs associated with Kallar grass roots (groups C, D) and a group of strains (E) isolated from fungi were analysed. They were compared by PAGE analyses of cellular proteins, genomic fingerprints, morphological and nutritional features to new isolates from rice roots. All strains within groups C, D and E containing 5-12 isolates showed group-specific cell and colony morphology and carbon source utilization patterns, with exception of the obligately microaerobic strain BS20-3, a member of group C. All strains, with this exception, also had almost indistinguishable electrophoretic protein patterns and genomic fingerprints generated with tDNA-directed primers, suggesting they belong to the same species. Phylogenetic analyses of almost complete 16S rDNA sequences carried out with three different algorithms (neighbour-joining, maximum-likelihood, parsimony) revealed that Azoarcus sensu lato is not monophyletic. Groups C, D and E formed three distinct lineages located between the Azoarcus/Thauera and the Rhodocyclus clusters. Phylogenetic distances between groups C, D and E were as large as between other genera (93-94% sequence similarity). This suggested they have the rank of three different genera. Since it was possible to differentiate them from each other and other related bacteria by phenotypic features, three new genera with one type species each are proposed: Azovibrio restrictus gen. nov., sp. nov., Azospira oryzae gen. nov., sp. nov. and Azonexus fungiphilus gen. nov., sp. nov.

    Two Gram-positive bacteria, designated strains Aji5-31(T) and Ngc37-23(T), were isolated from the intestinal tracts of fishes. 16S rRNA gene sequence analysis indicated that both strains were related to the members of the family Dermatophilaceae, with 95.6-96.9% 16S rRNA gene sequence similarities. The family Dermatophilaceae contains 2 genera and 3 species: Dermatophilus congolensis, Dermatophilus chelonae and Kineosphaera limosa. However, it has been suggested that the taxonomic position of D. chelonae should be reinvestigated using a polyphasic approach, because the chemotaxonomic characteristics are not known (Stackebrandt, 2006; Stackebrandt and Schumann, 2000). Our present study revealed that strains Aji5-31(T), Ngc37-23(T) and D. chelonae NBRC 105200(T) should be separated from the other members of the family Dermatophilaceae on the basis of the following characteristics: the predominant menaquinone of strain Aji5-31(T) is MK-8(H(2)), strain Ngc37-23(T) possesses iso- branched fatty acids as major components, and the menaquinone composition of D. chelonae is MK-8(H(4)), MK-8 and MK-8(H(2)) (5 : 3 : 2, respectively). On the basis of these distinctive phenotypic characteristics and phylogenetic analysis results, it is proposed that strains Aji5-31(T) and Ngc37-23(T) be classified as two novel genera and species of the family Dermatophilaceae. The names are Mobilicoccus pelagius gen. nov., sp. nov. and Piscicoccus intestinalis gen. nov., sp. nov., and the type strains are Aji5-31(T) (=NBRC 104925(T) =DSM 22762(T)) and Ngc37-23(T) (=NBRC 104926(T) =DSM 22761(T)), respectively. In addition, D. chelonae should be reassigned to a new genus of the family Dermatophilaceae with the name Austwickia chelonae gen. nov., comb. nov.

    2009-11-01

    Full Text Available Este artículo revisa conceptos actuales sobre determinación y diferenciación sexual con base en el estudio genético de una niña de 13 años que consultó por talla baja y aumento de peso. El examen físico mostró Tanner I en mamas y en vello púbico, sin signos de androgenización. Mientras el nivel de la hormona de crecimiento (GH era normal, las hormonas folículoestimulante (FSH y luteinizante (LH estaban aumentadas. Mediante laparoscopia y posterior estudio patológico se demostró la presencia de gonadas rudimentarias con ausencia de tejido testicular. Aunque el cariotipo obtenido fue 47XYY y el análisis molecular identificó la presencia del gen SRY, su funcionalidad es incierta, lo que hace necesaria su secuenciación, con la finalidad de determinar posibles mutaciones. En respuesta a la terapia con estrógenos y progesterona se desarrollaron tanto los caracteres sexuales secundarios como una menstruación normal. Aunque es posible que en la paciente haya una doble alteración genética donde concurran la mutación de novo de un gen y una no disyunción en la meiosis paterna, el caso descrito es ilustrativo de la importancia del estudio genético en la evaluación de la disgenesia gonadal.

    Full Text Available El objetivo de este trabajo fue evaluar marcadores moleculares y caracteres cuantitativos en un cruzamiento dialélico completo sin recíprocos, entre cinco líneas recombinantes de tomate y sus híbridos. Se obtuvieron perfiles de AFLP ("amplified fragment length polymorphism" y de polipéptidos del pericarpio en cuatro estados de madurez del fruto de 15 genotipos. Se evaluaron, entre otros: peso, acidez titulable, pH, vida poscosecha y firmeza. Se calculó el porcentaje de polimorfismo para los marcadores moleculares y el porcentaje de variabilidad genética para los caracteres cuantitativos en el grupo de líneas recombinantes, el de híbridos y el conjunto de genotipos. Se realizaron análisis de agrupamiento con cada nivel de variación genética. Para AFLP, el porcentaje de polimorfismo varió entre 34 y 54% y, para los perfiles polipeptídicos, entre 40 y 78%. Mayor polimorfismo fue observado en el grupo de híbridos. La variabilidad genética fue de 100% para acidez y 34% para firmeza, con los mayores valores en los parentales. La similitud genética varió entre los genotipos según el nivel de variación genética; pero la consistencia en el agrupamiento de algunas líneas recombinantes y sus híbridos fue conservada, lo que evidenció asociaciones entre los datos moleculares y fenotípicos.

    Full Text Available As técnicas multivariadas, para estimar a diversidade genética de um grupo de progenitores, têm sido utilizadas com freqüência pelos melhoristas de plantas. Os progenitores são utilizados em cruzamentos biparentais ou múltiplos, para formação de populações segregantes que tenham maior probabilidade de recuperação de genótipos superiores. Este trabalho foi realizado com o objetivo de identificar clones de guaranazeiro produtivos e divergentes que possam ser utilizados em um programa de cruzamentos para obter híbridos com alto valor heterótico e materiais para propagação vegetativa. Foram avaliados 148 clones de guaranazeiro atualmente em uso no programa de melhoramento genético da Embrapa-Centro de Pesquisa Agroflorestal da Amazônia Ocidental. Utilizou-se, para estimativa da divergência genética, a análise de agrupamento, em que a medida de dissimilaridade utilizada foi a distância euclidiana média padronizada e os métodos de agrupamento de otimização de Tocher e do vizinho mais próximo para construção do dendrograma entre grupos de clones. Houve a formação de sete grupos divergentes de clones. Concluiu-se que a divergência genética entre os clones não é grande, pois dois grupos foram formados com dois clones e três grupos foram formados somente com um único clone. Os clones CMU384 e CMU801 foram os mais próximos geneticamente e podem ser utilizados na formação de uma população com desenvolvimento vegetativo uniforme para uso em plantios comerciais.

    Full Text Available A transformação genética, que compreende a introdução de genes exógenos de forma controlada no genoma de uma célula vegetal e posterior regeneração da planta transgênica, tem contribuído com os programas de melhoramento genético de plantas pela obtenção de genótipos com novas características de interesse. O melhoramento de espécies florestais é limitado por características intrínsecas a tais espécies, como a altura dos indivíduos e o ciclo longo de vida. A transformação genética constitui, portanto, uma alternativa para a obtenção de espécies florestais com características desejáveis em um menor espaço de tempo. Plantas transgênicas com resistência a determinadas pragas, com melhor qualidade de madeira, maior produção de biomassa, tolerância a herbicidas, entre outras características de interesse, já foram obtidas para diferentes espécies florestais de importância econômica como álamo, eucalipto e pinheiros em geral. Este trabalho mostra a importância da transformação genética, associada a outras técnicas biotecnológicas no melhoramento de espécies florestais, as técnicas de transformação mais utilizadas e as características que já foram introduzidas nessas espécies pela transformação.

    Studying halophiles from different environments of Earth provide new insights into our search for life in the universe. Haloarchaea show some unique characteristics and physiological adaptations like acidic proteins against harsh environments such as natural brine with salt concentration approaching saturation (5 M) and regions with low active water. These properties make haloarchaea interesting candidate for astrobiological studies. Halovarius luteus gen. nov., sp. nov. a novel extremely halophilic archaeon from Urmia salt lake, in Iran has been chosen to explore its resistance against a series of extreme conditions. The aim of this study is to assess the resistance of strain DA50T under the effects of simulated space conditions like simulated microgravity, hypergravity, and desiccation. In this paper we will discuss the results of these studies where we specifically focus on changes in carotenoid pigments production and whole cell proteome. This is the first report of very novel Iranian archaea in response to extreme space conditions. The pigments were extracted by acetone and methanol. Pigments were analyzed by scanning the absorbance spectrum in the UV-VIS spectrophotometer. And they were separated by TLC. Whole protein from cell lysate supernatant was extracted after lysis with Bacterial Protein Extraction Reagent and fractionated by RP-HPLC using C18 column. Proteome analyzed by electrophoresis (SDS-PAGE), and MALDI-TOF. Carotenoid pigments are formed under different extreme conditions such as dry environment and gravitational changes. Also the protein composition exhibits alterations after exposure to the same conditions. Our conclusion is that pigments and proteins formation depend on the growth circumstances. Halophiles use this as an adaptation to survive under different environmental conditions.

Em particular, visa analisar as condições sociais que levaram à colaboração entre os uros, um grupo indígena que habita as ilhas flutuantes do lago Titicaca (Peru, e pesquisadores do projeto Genográfico. Os uros, cujas reivindicações de uma identidade étnica diferenciada eram altamente contestadas no âmbito local, se associaram aos geneticistas com o objetivo de obter um apoio científico para a afirmação dessa identidade e como parte das suas estratégias políticas e demandas territoriais. Assim, esse caso contribui ao maior entendimento da incorporação da pesquisa genética dentro de políticas conceituais travadas em torno das identidades étnicas, bem como da articulação do conhecimento genético com registros preexistentes para definir tais identidadesThe objective of this paper is to explore the interrelations between genetic research with human populations, the political strategies of indigenous movements and processes of identity formation. In particular, it will analyse the social conditions that have resulted in the collaboration between the Uros, an indigenous group living on the floating islands of Lake Titicaca (Peru, and researchers of the Genographic project. The Uros, whose claims to a differentiated ethnic identity were highly contested within the local context, engaged with geneticists with the aim to obtain scientific support for this identity. This was part of their political strategies for their territorial rights. As such, this case offers new insights into the incorporation of genetic research within the conceptual politics waged around ethnic identities, as well as the articulation of genetic knowledge with pre-existing registers to define such identities

Vários fatores globais prometem aumentar a futura demanda para pesquisa e serviços de saúde em genética moralmente conscientes. Embora os enfermeiros sejam o maior grupo profissional, prestando cuidado de saúde no mundo todo, eles não tomaram a liderança rumo a esse desafio. Insights, a partir da análise feminista, ajudam a esclarecer algumas das relações sociais e dos obstáculos culturais que têm impedido a integração da tecnologia genética na área da enfermagem. Um modelo alternativo é sugerido - o modelo transdisciplinar -, o qual foi desenvolvido inicialmente por uma enfermeira e introduzido, na década de 1970, na prestação do cuidado em saúde e no serviço social para crianças com déficit de desenvolvimento. Esse modelo holístico permite que todo profissional de saúde tenha a mesma voz ao determinar como o cuidado de saúde em genética será globalizado.Genetic information and technologies are increasingly important in health care, not only in technologically advanced countries, but world-wide. Several global factors promise to increase future demand for morally conscious genetic health services and research.

Insights from feminist analysis help to illuminate some of the social institutions and cultural obstacles that have impeded the integration of genetics technology into the discipline of nursing. An alternative model is suggested - the transdisciplinary model - which was developed initially by a nurse and introduced in the 1970s into the delivery of health care and social services for children with developmental disabilities.

    Intuition and insight share similar cognitive and neural basis. Though, there are still some essential differences between the two. Here in this short review, we discriminated between intuition, and insight in two aspects. First, intuition, and insight are toward different aspects of information processing. Whereas intuition involves judgment about "yes or no," insight is related to "what" is the solution. Second, tacit knowledge play different roles in between intuition and insight. On the one hand, tacit knowledge is conducive to intuitive judgment. On the other hand, tacit knowledge may first impede but later facilitate insight occurrence. Furthermore, we share theoretical, and methodological views on how to access the distinction between intuition and insight.

    GenGIS is free and open source software designed to integrate biodiversity data with a digital map and information about geography and habitat. While originally developed with microbial community analyses and phylogeography in mind, GenGIS has been applied to a wide range of datasets. A key feature of GenGIS is the ability to test geographic axes that can correspond to routes of migration or gradients that influence community similarity. Here we introduce GenGIS version 2, which extends the linear gradient tests introduced in the first version to allow comprehensive testing of all possible linear geographic axes. GenGIS v2 also includes a new plugin framework that supports the development and use of graphically driven analysis packages: initial plugins include implementations of linear regression and the Mantel test, calculations of alpha-diversity (e.g., Shannon Index) for all samples, and geographic visualizations of dissimilarity matrices. We have also implemented a recently published method for biomonitoring reference condition analysis (RCA), which compares observed species richness and diversity to predicted values to determine whether a given site has been impacted. The newest version of GenGIS supports vector data in addition to raster files. We demonstrate the new features of GenGIS by performing a full gradient analysis of an Australian kangaroo apple data set, by using plugins and embedded statistical commands to analyze human microbiome sample data, and by applying RCA to a set of samples from Atlantic Canada.

    Pseudomonas flectens Johnson 1956, a plant-pathogenic bacterium on the pods of the French bean, is no longer considered to be a member of the genus Pseudomonas sensu stricto. A polyphasic approach that included examination of phenotypic properties and phylogenetic analyses based on 16S rRNA, rpoB and atpD gene sequences supported the transfer of Pseudomonas flectens Johnson 1956 to a new genus in the family Enterobacteriaceae as Phaseolibacter flectens gen. nov., comb. nov. Two strains of Phaseolibacter flectens were studied (ATCC 12775(T) and LMG 2186); the strains shared 99.8 % sequence similarity in their 16S rRNA genes and the housekeeping gene sequences were identical. Strains of Phaseolibacter flectens shared 96.6 % or less 16S rRNA gene sequence similarity with members of different genera in the family Enterobacteriaceae and only 84.7 % sequence similarity with Pseudomonas aeruginosa LMG 1242(T), demonstrating that they are not related to the genus Pseudomonas. As Phaseolibacter flectens formed an independent phyletic lineage in all of the phylogenetic analyses, it could not be affiliated to any of the recognized genera within the family Enterobacteriaceae and therefore was assigned to a new genus. Cells were Gram-negative, straight rods, motile by means of one or two polar flagella, fermentative, facultative anaerobes, oxidase-negative and catalase-positive. Growth occurred in the presence of 0-60 % sucrose. The DNA G+C content of the type strain was 44.3 mol%. On the basis of phenotypic properties and phylogenetic distinctiveness, Pseudomonas flectens Johnson 1956 is transferred to the novel genus Phaseolibacter gen. nov. as Phaseolibacter flectens gen. nov., comb. nov. The type strain of Phaseolibacter flectens is ATCC 12775(T) = CFBP 3281(T) = ICMP 745(T) = LMG 2187(T) = NCPPB 539(T).

    The alkaline earth nitridogermanate nitrides AE(7)[GeN(4)]N(2) (AE = Ca, Sr) have been synthesized using a Na flux technique in sealed Ta tubes. According to single-crystal X-ray diffraction the isotypic compounds crystallize in space group Pbcn (No. 60) with Z = 4, (Sr(7)[GeN(4)]N(2): a = 1152.6(2), b = 658.66(13), c = 1383.6(3) pm, V = 1050.5(4) x 10(6) pm(3), R1 = 0.049; Ca(7)[GeN(4)]N(2): a = 1082.6(2), b = 619.40(12), c = 1312.1(3) pm, V = 879.8(3) x 10(6) pm(3), R1 = 0.016). Owing to the high N/Ge ratio, the compounds contain discrete N(3-) ions coordinated by six AE(2+) besides discrete [GeN(4)](8-) tetrahedrons. One of the AE(2+) ion is coordinated by only four N(3-) ions, which is rather an unusual low coordination number for Sr(2+). Together with the isolated [GeN(4)](8-) tetrahedrons, these Sr(2+) ions form chains of alternating cation centered edge sharing tetrahedrons. The electronic structure and chemical bonding in Sr(7)[GeN(4)]N(2) has been analyzed employing linear muffin-tin orbital (LMTO) band structure calculations.

  14. TopoGen: A Network Topology Generation Architecture with application to automating simulations of Software Defined Networks

    CERN Document Server

    Laurito, Andres; The ATLAS collaboration

    2017-01-01

    Simulation is an important tool to validate the performance impact of control decisions in Software Defined Networks (SDN). Yet, the manual modeling of complex topologies that may change often during a design process can be a tedious error-prone task. We present TopoGen, a general purpose architecture and tool for systematic translation and generation of network topologies. TopoGen can be used to generate network simulation models automatically by querying information available at diverse sources, notably SDN controllers. The DEVS modeling and simulation framework facilitates a systematic translation of structured knowledge about a network topology into a formal modular and hierarchical coupling of preexisting or new models of network entities (physical or logical). TopoGen can be flexibly extended with new parsers and generators to grow its scope of applicability. This permits to design arbitrary workflows of topology transformations. We tested TopoGen in a network engineering project for the ATLAS detector ...

  15. No quenching of magnetic moment for the GenCo (n=1-13) clusters: First-principles calculations

    Science.gov (United States)

    Jing, Qun; Tian, Fu-yang; Wang, Yuan-xu

    2008-03-01

    The authors predict that for the GenCo (n=1-13) clusters the magnetic moment does not quench, which is dark contrast to the previous results with transition-metal-doped Sin clusters. It may be due to the unpaired electrons of the Co atom in the clusters. For the ground state structures of the GenCo (n⩾9) clusters, the Co atom completely falls into the center of the Ge outer frame, forming metal-encapsulated Gen cages. The doping of the Co atom enhances the stability of the host Gen clusters. The Ge10Co cluster with the bicapped tetragonal antiprism structure is more stable than others, which agrees very well with the results of the experiment of the Co /Ge binary clusters by the laser vaporization.

    A new species of nematode, Squamasnema amazonica n. gen. n. sp., is described based on specimens found parasitizing the small intestine of Proechimys roberti (Rodentia: Echimyidae) collected during a survey of the fauna of Tapirapé-Aquirí National Forest (Brazil, Eastern Brazilian Amazon). The nematodes were fixed and processed for light microscopy and scanning electron microscopy (SEM). These nematodes were classified under the family Heligmonellidae and the subfamily Heligmonellinae. Although several species in the family Heligmonellidae exhibit discontinuous ridges, Squamasnema n. gen. and Trichotravassosia are the only genera with columns of scales along their entire body, as an apomorphy of the synlophe. Squamasnema n. gen. has columns of cuticular cells along its body, except for on the left flank, and exhibits a synlophe with no size gradient or inclination and does not present chitinized structures supporting the synlophe. Therefore, due to these morphological differences of Squamasnema n. gen., the creation of a new genus was necessary.

    IceCube is a neutrino observatory located at the geographic South Pole. The main backgrounds for IceCube's primary goal, the measurement of astrophysical neutrinos, are muons and neutrinos from cosmic-ray air showers in the Earth's atmosphere. Strong supression of these backgrounds from the Southern hemisphere has been demonstrated by coincident detection of these air showers with the IceTop surface detector. For an extended instrument, IceCube-Gen2, it is considered to build an enlarged surface array, IceVeto, that will improve the detection capabilities of coincident air showers. We will present simulation studies to estimate the IceVeto capabilities to optimize the IceCube-Gen2 design.

    Keller, J.; Blarigan, P. Van [Sandia National Labs., Livermore, CA (United States)

    1998-08-01

    In this manuscript the authors report on two projects each of which the goal is to produce cost effective hydrogen utilization technologies. These projects are: (1) the development of an electrical generation system using a conventional four-stroke spark-ignited internal combustion engine generator combination (SI-GenSet) optimized for maximum efficiency and minimum emissions, and (2) the development of a novel internal combustion engine concept. The SI-GenSet will be optimized to run on either hydrogen or hydrogen-blends. The novel concept seeks to develop an engine that optimizes the Otto cycle in a free piston configuration while minimizing all emissions. To this end the authors are developing a rapid combustion homogeneous charge compression ignition (HCCI) engine using a linear alternator for both power take-off and engine control. Targeted applications include stationary electrical power generation, stationary shaft power generation, hybrid vehicles, and nearly any other application now being accomplished with internal combustion engines.

    Highlights: • Thermal resistance of advanced stainless steels were observed at 1000 °C. • GEN IV candidate steels were confronted to classic AISI steels. • ODS AISI 316 has weaker thermal resistance than classic AISI steel. • Ferritic ODS steels and NF 709 has better thermal resistance than AISI steels. - Abstract: Candidate stainless steels for GEN IV reactors were investigated in term of thermal and corrosion stability at high temperatures. New austenitic steel (NF 709), austenitic ODS steel (ODS 316) and two ferritic ODS steels (MA 956 and MA 957) were exposed to around 1000 °C in inert argon atmosphere at pressure of ∼8 MPa. The steels were further studied in a light of vacancy defects presence by positron annihilation spectroscopy and their thermal resistance was confronted to classic AISI steels. The thermal strain supported a creation of oxide layers observed by scanning electron microscopy (SEM).

    Full Text Available ResumoThis review aims at addressing the main issues related to genetic improvement applied to fish species with zootechnical potential, such as selection, genetic parameters and use of biotechnology as well as address the importance of this area of study for the expansion of aquaculture and its development trend. Fish breeding is one of the most important areas of study for fish production development. Important techniques are applied in order to advance genetic progress in fish breeding (e.g., individual selection, genetic parameters estimation and the use of biotechnology. Traditional breeding in fish farming has been conducted mainly through biometric analysis, which helps in choosing selection criteria and in the assessment of genetic parameters such as heritability and correlations between interesting traits. The use of biotechnology in fish breeding has been successful; it is an important strategy that allows breeding results to be achieved faster, although at a greater cost than traditional breeding. Fish breeding in Brazil is currently in its initial stages; however, it is a field with great growth expectations, and there is still significant research to be conducted in this area.AbstractEsta revisão tem como objetivo a abordagem dos principais aspectos relacionados ao melhoramento genético aplicado em espécies de peixes com potencial zootécnico, tais como seleção, parâmetros genéticos e utilização da biotecnologia, bem como abordar a importância desta área de estudos para a ampliação da aquicultura e sua tendência de desenvolvimento.

    Full Text Available O alcoolismo é um problema de saúde pública de escala mundial. O abuso e dependência combinados afetam aproximadamente 8% da população brasileira, gerando um grande custo social. O reconhecimento da existência de uma herdabilidade significativa contribuiu para o entendimento do problema como uma doença específica com origem biológica. Os avanços no conhecimento da neurobiologia da dependência permitiram delimitar uma série de genes candidatos para a predisposição. Atualmente, iniciam-se os estudos sobre o papel de polimorfismos genéticos na resposta ao tratamento. A integração de abordagens clínicas, epidemiológicas e de genética molecular pode identificar grupos clínicos mais responsivos a abordagens terapêuticas específicas.

    We examined the molecular phylogeny and ultrastructure of Chlorogonium and related species to establish the natural taxonomy at the generic level. Phylogenetic analyses of 18S rRNA and RUBISCO LSU (rbcL) gene sequences revealed two separate clades of Chlorogonium from which Chlorogonium (Cg.) fusiforme Matv. was robustly separated. One clade comprised Cg. neglectum Pascher and Cg. kasakii Nozaki, whereas the other clade included the type species Cg. euchlorum (Ehrenb.) Ehrenb., Cg. elongatum (P. A. Dang.) Francé, and Cg. capillatum Nozaki, M. Watanabe et Aizawa. On the basis of unique ultrastructural characteristics, we described Gungnir Nakada gen. nov. comprising three species: G. neglectum (Pascher) Nakada comb. nov., G. mantoniae (H. Ettl) Nakada comb. nov., and G. kasakii (Nozaki) Nakada comb. nov. We also emended Chlorogonium as a monophyletic genus composed of Cg. euchlorum, Cg. elongatum, and Cg. capillatum. Because Cg. fusiforme was distinguished from the redefined Chlorogonium and Gungnir by the structure of its starch plate, which is associated with pyrenoids, we reclassified this species as Rusalka fusiformis (Matv.) Nakada gen. et comb. nov.

    Chlamydomonas (Cd.) is one of the largest but most polyphyletic genera of freshwater unicellular green algae. It consists of 400-600 morphological species and requires taxonomic revision. Toward reclassification, each morphologically defined classical subgenus (or subgroup) should be examined using culture strains. Chlamydomonas subg. Amphichloris is characterized by a central nucleus between two axial pyrenoids, however, the phylogenetic structure of this subgenus has yet to be examined using molecular data. Here, we examined 12 strains including six newly isolated strains, morphologically identified as Chlamydomonas subg. Amphichloris, using 18S rRNA gene phylogeny, light microscopy, and mitochondria fluorescent microscopy. Molecular phylogenetic analyses revealed three independent lineages of the subgenus, separated from the type species of Chlamydomonas, Cd. reinhardtii. These three lineages were further distinguished from each other by light and fluorescent microscopy-in particular by the morphology of the papillae, chloroplast surface, stigmata, and mitochondria-and are here assigned to three genera: Dangeardinia emend., Ixipapillifera gen. nov., and Rhysamphichloris gen. nov. Based on the molecular and morphological data, two to three species were recognized in each genus, including one new species, I. pauromitos. In addition, Cd. deasonii, which was previously assigned to subgroup "Pleiochloris," was included in the genus Ixipapillifera as I. deasonii comb. nov.

    Four isolates, belonging to the deep-branching phylum Planctomycetes, were recovered from the biofilm of two marine macroalgae, Ulva sp. and Laminaria sp., from the Northern coast of Portugal. These strains were light pink- or red-pigmented; the cells were variable in shape and usually organized in rosettes. They had a dimorphic cell cycle with budding reproduction. The organisms were chemoheterotrophic, strictly aerobic and mesophilic. The 16S rRNA gene sequence analysis showed that the strains belong to the family Planctomycetaceae with Rhodopirellula as the closest genus. The isolates form two separate branches (strain LF1(T) forms one branch and the strains UC8(T), UF3 and UF42 form a second branch) clearly separated from Rhodopirellula baltica with 94.2% and 93.8% 16S rRNA gene sequence similarity, respectively. Based on differential characteristics that distinguish the novel genera from R. baltica, such as cell size and shape, ultrastructure, enzymatic activities, substrate utilization pattern, fatty acid composition, phospholipid profiles and phylogeny we propose that the isolates represent two novel genera of the order Planctomycetales, Roseimaritima ulvae gen. nov., sp. nov. (type strain is UC8(T)=DSM 25454(T)=LMG 27778(T)) and Rubripirellula obstinata gen. nov., sp. nov. (type strain is LF1(T)=LMG 27779(T)=CECT 8602(T)).

    Two new woloszynskioid dinoflagellates, Asulcocephalium miricentonis gen. et sp. nov. and Leiocephalium pseudosanguineum gen. et sp. nov., are described from Japanese freshwater ponds on the basis of bright field and fluorescence light microscopy, scanning and transmission electron microscopy, and molecular phylogeny inferred from rDNA sequences. Asulcocephalium miricentonis has a spherical anterior nucleus and chloroplast with a pyrenoid penetrated by the cytoplasm. This species has 9-12 latitudinal series of amphiesmal vesicles (AVs), including an apparently large AV on the right ventral side of the epicone. Leiocephalium pseudosanguineum has a U-shaped nucleus in the epicone and chloroplasts without a pyrenoid. This species has at least 24 latitudinal series of AVs. The characteristic features of both species were brick-like material (type E) in the eyespot and the lack of an apical furrow. These features coincide with those of Polarella glacialis, but the two species differ in cell shape, number and arrangement of AVs, shape of resting cysts, and habitats; i.e., P. glacialis has been reported only from marine cold waters. Molecular phylogeny revealed that A. miricentonis and L. pseudosanguineum were positioned in the Suessiaceae and closely related to Piscinoodinium sp., but their relationship to Polarella and other reported taxa was not supported.

    For years, systematics of three species, Urosomoida agilis (Engelmann, 1862) Hemberger in Foissner, 1982, Urosomoida longa (Gelei and Szabados, 1950) Foissner et al., 1991 and Oxytricha lanceolata Shibuya, 1930, has remained unresolved due to lack of adequate molecular data. Though, it is known since several years that the three species are not very closely related. In the present paper, 18S rRNA gene sequences for two key species, U. agilis and U. longa, and their morphology and morphometry have been analyzed. Molecular phylogeny inferred from maximum likelihood, neighbour joining and maximum parsimony methods has adequately removed ambiguity over their systematics. In phylogenetic trees, U. agilis clustered consistently with non-stylonychine oxytrichids. Both Urosomoida longa and Oxytricha lanceolata clustered consistently away from U. agilis and O. granulifera, the type species of the genera Urosomoida and Oxytricha, respectively. As a result of the current molecular phylogenetic investigation and based on previously inferred morphological and morphogenetic data it is proposed to remove Urosomoida longa and Oxytricha lanceolata from Urosomoida and incertae sedis in Oxytricha, respectively, and establish two new generic combinations, Hemiurosomoida longa gen. nov., comb. nov. and Heterourosomoida lanceolata gen. nov., comb. nov. for them.

    Full Text Available Earlier phylogenetic analyses of the marine Rhodobacteraceae (class Alphaproteobacteria genera Leisingera and Phaeobacter indicated that neither genus might be monophyletic. We here used phylogenetic reconstruction from genome-scale data, MALDI-TOF mass-spectrometry analysis and a re-assessment of the phenotypic data from the literature to settle this matter, aiming at a reclassification of the two genera. Neither Phaeobacter nor Leisingera formed a clade in any of the phylogenetic analyses conducted. Rather, smaller monophyletic assemblages emerged, which were phenotypically more homogeneous, too. We thus propose the reclassification of Leisingera nanhaiensis as the type species of a new genus as Sedimentitalea nanhaiensis gen. nov., comb. nov., the reclassification of Phaeobacter arcticus and Phaeobacter leonis as Pseudophaeobacter arcticus gen. nov., comb. nov. and Pseudophaeobacter leonis comb. nov., and the reclassification of Phaeobacter aquaemixtae, Phaeobacter caeruleus and Phaeobacter daeponensis as Leisingera aquaemixtae comb. nov., Leisingera caerulea comb. nov. and Leisingera daeponensis comb. nov. The genera Phaeobacter and Leisingera are accordingly emended.

Foram utilizados dados de 1280 codornas machos e fêmeas, provenientes de sete genótipos de codornas de corte (EV1, EV2, UFV1, UFV2, UFV3, LF1, LF2 e um de postura. Todas as codornas foram pesadas a cada sete dias, do nascimento aos 35 dias de idade. Foram ajustados os modelos Brody, Gompertz, Logístico, Richards e von Bertalanffy aos dados de peso corporal de todos os genótipos. As análises estatísticas foram realizadas utilizando-se o PROC NLIN do SAS (Statistical Analysis System, versão 9.0. Os critérios empregados para a escolha do melhor modelo para descrever a curva de crescimento foram o coeficiente de determinação ajustado (R2, o desvio padrão assintótico (DPA, o desvio médio absoluto dos resíduos (DMA, o índice assintótico (IA, o critério de informação bayesiano (BIC, o critério de Akaike (AIC e o quadrado médio do erro (QME. Todos os modelos não lineares testados convergiram, com exceção do modelo Brody, que não convergiu para nenhum genótipo avaliado. O modelo Richards não convergiu para o genótipo postura. Os parâmetros da curva de crescimento estimados pelos modelos indicaram maior precocidade, em geral, do genótipo postura comparado aos demais genótipos. O modelo Richards apresentou superestimação do ponto de inflexão para todos os genótipos, exceto para o genótipo postura. Os modelos Gompertz, Logístico e von Bertalanffy são recomendados para descrever o crescimento de codornas de corte dos grupos genéticos em estudo. O modelo Brody não convergiu, por isso não é recomendado para descrever o crescimento dos grupos genéticos de codornas em estudo.

Dentre elas, obtiveram uma cultivar de alface, denominada Uberlândia 10.000 com 10.200 UI de vitamina A em 100 gramas de folha fresca. Este trabalho objetivou comparar o grau de divergência genética entre a cultivar Uberlândia 10.000 e seus parentais para avaliar a eficiência da seleção utilizada, por meio da técnica AFLP. Foram utilizados os seguintes genótipos de alface: Maioba, Salad Bowl-Mimosa, Moreninha-de-Uberlândia, Vitória de Santo Antão, Uberlândia 10.000 lisa 8.ª e 9.ª geração e Uberlândia 10.000 crespa 8.ª e 9.ª geração. A técnica AFLP foi eficiente para identificar genótipos muito próximos e para estudos de progênies em alface. O primer PR15 permitiu a separação da forma lisa e crespa com 1,8% de divergência genética e a oitava da nona geração com apenas 0,71%. Com o estudo da filogenia da cultivar pode-se observar que o programa de melhoramento foi desenvolvido com sucesso, pois a cultivar obtida Uberlândia 10.000 possui alto teor de vitamina A e 92% de similaridade com o parental Vitória de Santo Antão. O primer PR11 conseguiu identificar polimorfismo entre cultivares de alta e baixa resistência à septoriose, sugerindo a possibilidade destas bandas estarem relacionadas à resistência.Considering the restricted diversity of species available to counteract vitamin deficiencies in Brazil, Kerr and coworkers have been engaged since 1981, in developing genetic improved garden vegetables rich in vitamin A.

    2005-12-01

    Full Text Available Abstract Background Improvements of bio-nano-technologies and biomolecular techniques have led to increasing production of high-throughput experimental data. Spotted cDNA microarray is one of the most diffuse technologies, used in single research laboratories and in biotechnology service facilities. Although they are routinely performed, spotted microarray experiments are complex procedures entailing several experimental steps and actors with different technical skills and roles. During an experiment, involved actors, who can also be located in a distance, need to access and share specific experiment information according to their roles. Furthermore, complete information describing all experimental steps must be orderly collected to allow subsequent correct interpretation of experimental results. Results We developed MicroGen, a web system for managing information and workflow in the production pipeline of spotted microarray experiments. It is constituted of a core multi-database system able to store all data completely characterizing different spotted microarray experiments according to the Minimum Information About Microarray Experiments (MIAME standard, and of an intuitive and user-friendly web interface able to support the collaborative work required among multidisciplinary actors and roles involved in spotted microarray experiment production. MicroGen supports six types of user roles: the researcher who designs and requests the experiment, the spotting operator, the hybridisation operator, the image processing operator, the system administrator, and the generic public user who can access the unrestricted part of the system to get information about MicroGen services. Conclusion MicroGen represents a MIAME compliant information system that enables managing workflow and supporting collaborative work in spotted microarray experiment production.

El análisis de la variación de las frecuencias alélicas totales indicó que el nivel de diferenciación interregional es bajo (Gst = 0.0025, lo que señala un bajo nivel de divergencia genética entre las regiones consideradas. Los valores de distancia genética (DA entre las regiones fueron consistentemente bajos; siendo los valores más altos los encontrados entre Montevideo vs. Centro y Centro vs. Sur. Los dendogramas confeccionados sobre la base de las distancias genéticas indican una clara separación de la región Centro de las otras regiones. Los porcentajes de mezcla estimados revelan que el aporte predominante para todas las regiones es el de origen europeo, seguido del amerindio, y por último el africano. Se observó una cierta heterogeneidad en la distribución de los porcentajes de mezcla entre las regiones consideradas, en particular el aporte africano, el que presentó su valor más alto en la región Sur (7.9%, seguido de Montevideo (5.1%. Los resultados obtenidos reflejan un intenso proceso de mestizaje, con posibles variaciones regionales.

    Phylogenetic analysis of 16S rDNA indicates that Brevibacterium incertum is not a member of the genus Brevibacterium but related to species of the genus Carnobacterium. Hence, Brevibacterium incertum is not a member of the class Actinobacteria but belongs to the phylogenetically defined broad Bacillus-Lactobacillus cluster. Based upon properties that taxonomically clearly distinguishes Brevibacterium incertum from species of the phylogenetic sister genus Carnobacterium, Brevibacterium incertum is reclassified as Desemzia incerta gen. nov., comb. nov.

    Genetics and genomics are increasingly relevant to primary healthcare but training is unavailable to many practitioners. Education that can be accessed by practitioners without cost or travel is essential. The Gen-Equip project was formed to provide effective education in genetics for primary healthcare in Europe and so improve patient care. Partners include patient representatives and specialists in genetics and primary care from six countries. Here, we report the progress and challenges involved in creating a European online educational program in genetics.

    Full Text Available RACIONAL: O câncer de estômago é o segundo tipo mais comum de neoplasia no mundo. A carcinogênese de estômago é processo de múltiplos passos, podendo manifestar-se em várias etapas como gastrite superficial, gastrite atrófica crônica, metaplasia intestinal, displasia e, finalmente, como um carcinoma. Essas condições costumam ser seqüenciais e ocorrer num período de muitos anos como resultado da exposição a uma variedade de fatores endógenos e exógenos, que causam alterações genéticas. Os recentes avanços da genética molecular têm mostrado que o acúmulo dessas várias anormalidades, incluindo a ativação de oncogenes e a inativação de genes supressores de tumores, resultam no desenvolvimento do câncer. Alterações genéticas descritas em carcinomas gástricos incluem amplificações e mutações dos genes c-ERBB2, K-RAS, c-MET e TP53. O ganho de cromossomos também foi encontrado em várias combinações com perda de outros cromossomos e pode estar associado com a expressão elevada de oncogenes, que contribuem com a progressão tumoral. CONCLUSÃO: Essas mudanças genéticas em carcinomas evidenciam o processo de múltiplas etapas da carcinogênese gástrica, por meio do acúmulo de uma série de alterações.

  20. Resolution of single and double Holliday junction recombination intermediates by GEN1.

    Genetic recombination provides an important mechanism for the repair of DNA double-strand breaks. Homologous pairing and strand exchange lead to the formation of DNA intermediates, in which sister chromatids or homologous chromosomes are covalently linked by four-way Holliday junctions (HJs). Depending on the type of recombination reaction that takes place, intermediates may have single or double HJs, and their resolution is essential for proper chromosome segregation. In mitotic cells, double HJs are primarily dissolved by the BLM helicase-TopoisomeraseIIIα-RMI1-RMI2 (BTR) complex, whereas single HJs (and double HJs that have escaped the attention of BTR) are resolved by structure-selective endonucleases known as HJ resolvases. These enzymes are ubiquitous in nature, because they are present in bacteriophage, bacteria, archaea, and simple and complex eukaryotes. The human HJ resolvase GEN1 is a member of the XPG/Rad2 family of 5'-flap endonucleases. Biochemical studies of GEN1 revealed that it cleaves synthetic DNA substrates containing a single HJ by a mechanism similar to that shown by the prototypic HJ resolvase, Escherichia coli RuvC protein, but it is unclear whether these substrates fully recapitulate the properties of recombination intermediates that arise within a physiological context. Here, we show that GEN1 efficiently cleaves both single and double HJs contained within large recombination intermediates. Moreover, we find that GEN1 exhibits a weak sequence preference for incision between two G residues that reside in a T-rich region of DNA. These results contrast with those obtained with RuvC, which exhibits a strict requirement for the consensus sequence 5'-(A)/TTT(G)/C-3'.

Se emplearon los métodos de infiltración mediante vacío, infección directa de explantes, transformación de polen, y microinyección de ovarios. La prueba histoquímica de expresión gus fue escogida como método de análisis en la determinación de transformantes positivos. Con las metodologías empleadas se detectaron puntos azules en el tejido vegetal, lo cual indica la expresión transitoria del transgen en los explantes utilizados. Los resultados obtenidos sugieren que la transformación genética en arveja cultivada en Colombia puede ser utilizada para la introducción de genes de interés como apoyo a los procesos de mejoramiento genético.Palabras clave: genotipos, expresión gus, fitomejoramiento.Abstract: Different genetic transformation alternatives were tested in “Santa Isabel” cultivar pea, in order to study the factors that affect the process. The methods used were infiltration with vacuum, direct infection of the explants, pollen transformation and ovary microinjection. The hystochemical test of  gus expression was chosen as analysis method in the determination of positive transformants. Blue spots in the plant tissue were detected, with the used methodologies, which indicates transient expression of the transgene in the explants utilized. The obtained results suggest that the genetic transformation in pea genotypes planted in Colombia can be used for the introduction of genes of interest as support to genetic improvement.Key words: genotypes, gus expressions, plant breeding.

    2013-12-01

    Full Text Available El extraordinario desarrollo de las técnicas genéticas, con su formidable capacidad de afectación a la autonomía personal y de invasión de los derechos individuales, está teniendo un impacto profundo en el pensamiento jurídico, obligándonos a revisar algunos de los presupuestos en que se funda nuestra concepción de los derechos fundamentales. Así, el reconocimiento del derecho del individuo a no conocer sus datos genéticos parece desafiar nociones esenciales como las de autonomía y racionalidad del sujeto de derechos, vinculadas en el proyecto ilustrado de emancipación del individuo a la idea de pleno acceso al conocimiento. Sin embargo, la propia idea de “ignorancia” no resulta ajena al discurso de fundamentación de los derechos fundamentales, como prueba el papel esencial que el “velo de la ignorancia” desempeña en la revisión de la tradición liberal efectuada por John Rawls. A partir de la teoría de éste y de John Stuart Mill se indaga en los fundamentos filosóficos del derecho a no saber los datos genéticos y en sus límites, ante la existencia de posibles derechos de terceros a acceder a esa información. Asimismo, se pone de manifiesto el papel que en este nuevo contexto juega el Derecho como instancia administradora del conocimiento y de la ignorancia, ante la amenaza de un determinismo genético que parece poner en cuestión en última instancia la idea misma de libertad individual.

Foi utilizada a técnica de grupos focais com 12 residentes de Pediatria em seu primeiro mês de curso, divididos em quatro grupos. Para a análise do material, foi escolhida a técnica da leitura isotópica. Os participantes demonstraram pouco interesse pelo assunto, mas tinham um grau razoável de conhecimento. Este conhecimento, entretanto, era pouco vinculado à prática clínica, sugerindo a necessidade de reformulação da formação médica. Os grupos mostraram consciência da alta prevalência e da grande morbidade das doenças genéticas, sinalizando que a nova geração de médicos pode ser mais sensível à questão da inserção da Genética na saúde pública. O Brasil está passando por um momento de transição epidemiológica, com o aumento proporcional das doenças de etiologia genética como causas de morbi-mortalidade, tornando necessária a inclusão dessas condições no planejamento para a gestão da saúde pública.

    The IceCube Neutrino Observatory is a cubic-kilometer Cherenkov telescope buried in the ice sheet at the South Pole that detects neutrinos of all flavors with energies from tens of GeV to several PeV. The instrument provided the first measurement of the flux of high-energy astrophysical neutrinos, opening a new window to the TeV universe. At the other end of its sensitivity range, IceCube has provided precision measurements of neutrino oscillation parameters that are competitive with dedicated accelerator-based experiments. Here we present design studies for IceCube Gen2, the next-generation neutrino observatory for the South Pole. Instrumenting a volume of more that 5 km{sup 3} with over 100 new strings, IceCube Gen2 will have substantially greater sensitivity to high-energy neutrinos than current-generation instruments. PINGU, a dense infill array, will lower the energy threshold of the inner detector region to 4 GeV, allowing a determination of the neutrino mass hierarchy. On the surface, a large air shower detector will veto high-energy atmospheric muons and neutrinos from the southern hemisphere, enhancing the reach of astrophysical neutrino searches. With its versatile instrumentation, the IceCube Gen2 facility will allow us to explore the neutrino sky with unprecedented sensitivity, providing new constraints on the sources of the highest-energy cosmic rays, and yield precision data on the mixing and mass ordering of neutrinos.
