Full Text Available La misión astrobiológica más importante que se ha realizado hasta la fecha ha sido sin duda el proyecto Vikingo de la NASA. Esta misión consistió en tres experimentos biológicos especialmente diseñados para la búsqueda de indicadores de vida en las capas superficiales del suelo marciano. Los tres experimentos dieron resultados positivos. Sin embargo, el análisis de materia orgánica en el suelo marciano demostró la ausencia total de carbono orgánico. Este hallazgo fue utilizado como uno de los argumentos más sólidos en contra de la existencia de vida en la superficie del planeta Marte. Como preparación para futuras misiones a Marte en búsqueda de vida es necesario probar los instrumentos en localidades terrestres que pudieran ser ambientes análogos a Marte. Uno de los desiertos más áridos del planeta es el de Atacama, en el norte de Chile. Estudios químicos y microbiológicos del suelo de Atacama sugieren que el corazón del desierto es en realidad un buen análogo de Marte, ya que no posee vida macroscópica y microscópica, tiene niveles muy bajos de materia orgánica, y sus suelos son muy reactivos. En colaboración con científicos franceses y estadounidenses, estamos preparando una misión robótica dirigida por la NASA para la búsqueda de vida pasada o presente en Marte por lo que el Desierto de Atacama en Chile es el escenario para la preparación de esta misión espacial.

Per accertare la presenza stabile della specie nella Riserva e lungo il tratto vercellese-alessandrino del Parco fluviale del Po, è stato applicato un metodo PCR-RFLP per l’analisi di mtDNA di origine fecale. A partire da gennaio 2007, sono state raccolte 212 feci attribuibili al genere Martes in base a forma e dimensioni. L’analisi di un campione di 117 feci (55% ha permesso di identificare 10 feci di martora e 15 di faina (M. foina, confermando la presenza della martora nella Riserva e accertandola per la prima volta in un’area collinare in sponda destra del Po (Camino, AL, circa 32 km a monte della Riserva. Resta da valutare se la scarsa resa dell’amplificazione del DNA (21,4% sia dovuta alla degradazione del materiale genetico o ad un numero elevato di feci di volpe (Vulpes vulpes erroneamente attribuite a Martes durante la fase di raccolta.

The merit of meritocracy.

Son Hing, Leanne S; Bobocel, D Ramona; Zanna, Mark P; Garcia, Donna M; Gee, Stephanie S; Orazietti, Katie

2011-09-01

We argue that the preference for the merit principle is a separate construct from hierarchy-legitimizing ideologies (i.e., system justification beliefs, prejudice, social dominance orientation), including descriptive beliefs that meritocracy currently exists in society. Moreover, we hypothesized that prescriptive beliefs about merit should have a stronger influence on reactions to the status quo when hierarchy-legitimizing ideologies are weak (vs. strong). In 4 studies, participants' preference for the merit principle and hierarchy-legitimizing ideologies were assessed; later, the participants evaluated organizational selection practices that support or challenge the status quo. Participants' prescriptive and descriptive beliefs about merit were separate constructs; only the latter predicted other hierarchy-legitimizing ideologies. In addition, as hypothesized, among participants who weakly endorsed hierarchy-legitimizing ideologies, the stronger their preference for the merit principle, the more they opposed selection practices that were perceived to be merit violating but the more they supported practices that were perceived to be merit restoring. In contrast, those who strongly endorsed hierarchy-legitimizing ideologies were always motivated to support the status quo, regardless of their preference for the merit principle.

Literatura y realidad histórica. Un reencuentro con Ezequiel Martínez Estrada y su interpretación del Martín Fierro

Directory of Open Access Journals (Sweden)

Amán Rosales Rodríguez

2010-01-01

Full Text Available The purpose of this paper is to critically review some of the main theoretical tenets in Ezequiel Martínez Estrada’s pessimistic stance about the Argentinean history and society of his time. Focusing on his critical remarks about the so-called «literatura o poesía gauchesca» as well as on his enthusiastic assessment of José Hernández’ Martín Fierro, the achievements and missing points in Martínez Estrada’s skeptical diagnosis will be underlined and put in broader philosophical context. For the Argentinean writer the controversial notion of a “superimposed reality” – as he infers its existence from the Martín Fierro – captures a kind of ambivalent metaphysical concurrence among the literary creation, the geographical setting and the sociopolitical state of the country.

Highlights: Black-Right-Pointing-Pointer We show that the MARTe is a candidate for ITER PSH. Black-Right-Pointing-Pointer We replace the old real-time feedback software using the MARTe framework. Black-Right-Pointing-Pointer We describe all the work done for the integration. - Abstract: Keeping in mind the necessities of a modern control system for fusion devices, such as modularity and a distributed architecture, an upgrade of the present FTU feedback control system was planned, envisaging also a possible reutilization in the proposed FAST experiment [1]. For standardization and efficiency purposes we decided to adopt a pre-existent ITER-relevant framework called MARTe [2], already used with success in other European Tokamak devices [3]. Following the developments shown in [4], in this paper we report on the structure of the new feedback system, and how it was integrated in the current control structure and pulse programming interface, and in the other MARTe systems already in FTU: RT-ODIN [5] and the ECRH and LH [6] satellite stations. The new feedback system has been installed in the FTU backup station (known as 'Feedback B'), which shares the input signals with the actual feedback system, in order to simplify the validation and debug of the new controller by testing it in parallel with the current one. Experimental results are then presented.

Highlights: • Similarities and differences between DCS and MARTe. • Identifies the state-of-the-art in terms of software frameworks for fusion control. • Interfaces developed for realtime and non-realtime communication between DCS and MARTe. • An algorithm replicated in DCS and MARTe produces identical results and good performance. • The start of collaboration to develop a new framework for ITER PCS. - Abstract: Fusion experiments place high demands on real-time control systems. Within the fusion community two modern framework-based software architectures have emerged as powerful tools for developing algorithms for real-time control of complex systems while maintaining the flexibility required when operating a physics experiment. The two frameworks are known as DCS (Discharge Control System), from ASDEX Upgrade and MARTe (Multithreaded Application Real-Time executor), originally from JET. Based on the success of DCS and MARTe, ITER has chosen to develop a framework architecture for its Plasma Control System which will adopt major design concepts from both the existing frameworks. This paper describes a coupling of the two existing frameworks, which was undertaken to explore the degree of similarity and compliance between the concepts, and to extend their capabilities. DCS and MARTe operate in parallel with synchronised state machines and a common message logger. Configuration data is exchanged before the real-time phase. During the real-time phase, structured data is exchanged via shared memory and an existing DCS algorithm is replicated within MARTe. The coupling tests the flexibility and identifies the respective strengths of the two frameworks, providing a well-informed basis on which to move forward and design a new ITER real-time framework.

[Population aspects of sexual dimorphism in guild of the Mustelidae: Mustela lutreola, Neovison vison, Mustela putorius, Martes martes as an example].

Korablev, M P; Korablev, N P; Korablev, P N

2013-01-01

Size sexual dimorphism was investigated on 695 skulls of four Mustelidae species. By extent of increasing of differences between sexes the species are placed in following order: European pine marten (Martes martes), European mink (Mustela lutreola), American mink (Neovison vison), and European polecat (Mustela putorius). Extent of the dimorphism characterizes ecological plasticity of the species and is population characteristic. It is shown that M. martes takes specific and relatively narrow ecological niche of forest ecosystems, entering into weak competitive relationships with smaller Mustelidae species. The level of sexual dimorphism of M. lutreola, N. vison and M. putorius reflects intensity of its interspecific relationships within study area. High level of sexual dimorphism of M. putorius is determined by further divergence of ecological niches of males and females, and also appears to be compensatory mechanism reducing consequences of hardened environmental requirements.

Variabilità microsatellitare in popolazioni italiane di martora, Martes martes

Directory of Open Access Journals (Sweden)

Licia Colli

2003-10-01

Full Text Available La martora, Martes martes, è un mustelide storicamente presente su gran parte del territorio italiano, soprattutto dove siano presenti foreste mature altamente strutturate e ricche di risorse. Nel corso dei decenni passati, cause quali la deforestazione con conseguente frammentazione dell'habitat, la caccia e la persecuzione da parte dell'uomo hanno portato ad un sensibile declino sia nel numero d'individui sia di popolazioni in tutta l'Europa. Frammentazione degli areali e diminuzione del numero di soggetti costituiscono le cause principali di un limitato flusso genico con conseguente formazione di popolazioni isolate di martora e perdita di variabilità genetica (Kyle et al., 2003. Per queste ragioni la martora risulta attualmente tutelata secondo quanto previsto dalla Convenzione di Berna (appendice III e dalla Direttiva europea 92/43/CEE "Habitats & Species". Di fronte a prospettive di tipo conservazionistico, diventa necessario disporre di metodologie per la valutazione della variabilità residua nella specie a livello d'individui e di popolazioni. Secondo numerosi Autori, i microsatelliti costituiscono marcatori molto efficaci nella descrizione della struttura genetica e della storia demografica di specie (Beaumont & Bruford, 1999; Linares, 1999. Il presente lavoro propone i risultati ottenuti attraverso il confronto di due campioni costituiti da individui di Martes martes provenienti dalla Sardegna (25 esemplari e dal territorio italiano (6 esemplari. L'analisi è stata condotta a livello di 7 loci microsatellitari dinucleotidici polimorfici. Il valore di F_ST calcolato dal confronto dei due gruppi è risultato pari a 0,102 e ricade nel range di variazione identificato di recente in popolazioni nord-europee di martora (Kyle et al., 2003. L'analisi della varianza molecolare (AMOVA, condotta a due livelli gerarchici, ha permesso in particolare di ripartire la varianza del campione

From Sarmiento to Martí and Hostos: Extricating the Nation from Coloniality

Directory of Open Access Journals (Sweden)

Thomas Ward

2007-10-01

Full Text Available The present article examines constructions of  race, nation and mestizaje in work of Domingo  Faustino Sarmiento, José Martí and Eugenio  Maria de Hostos. The first championed the prevailing nineteenth-century view that humanity  was being debilitated by a constant battle between  civilization and barbarism while the two Antilleans questioned it in their search for a society  liberated from coloniality. Martí denied the notion  of privilege based on Europeanness, proclaiming  that whites, blacks, indigenous and mixed-race  peoples could all claim equal rights under natural  law. Hostos agreed with Martí but took his recommendation one step further by proposing race  mixing, with all ethnic groups equally forming a  new society. Therefore Martí’s negation of racial  differences becomes with Hostos a quest for a  society that would eventually become homogeneous through miscegenation. The study concludes  that there is a timelessness inherent to Martí and  Hostos’s work that still speaks to us today in the  midst of a new awareness of ethnicity’s impact on  society. Resumen:De Sarmiento a Martí y Hostos: Rescatando al país de la colonialidadEl presente artículo examina las construcciones de  raza, nación y mestizaje en las obras de Domingo  Faustino Sarmiento, José Martí y Eugenio María de  Hostos.

José Martí y la ciencia

Directory of Open Access Journals (Sweden)

José Suárez Lezcano

2015-11-01

Full Text Available Nuestro José Martí, ejemplo de una formación humanística integral, escribió en una carta a María Mantilla:”Donde yo encuentro poesía mayor es en los libros de ciencia…” Martí vio la ciencia como un fenómeno social y consideró que el desarrollo científico técnico debía estar en función de la satisfacción de las necesidades de las grandes mayorías. Su sistemática voluntad  de cultivarse, de tratar de entender al mundo y no sólo de vivirlo, de razonarlo, fue el motor principal que llevaría a Martí a hacerse de una cultura científica y técnica poco común entre los hombres de su época. También el hecho de vivir durante muchos años en los Estados Unidos le permitió analizar con  profundidad y realismo la sociedad de la época, y por tanto llegó a tener una visión muy avanzada de la relación hombre – naturaleza - sociedad, llegando a convertirse en un gran divulgador de los avances de la ciencia y la técnica de aquella época. La originalidad del periodismo de nuevo tipo que inicia José Martí como vehículo para la divulgación científico - técnica encuentra una de sus más altas expresiones en la revista “La América”. Esta publicación había comenzado en abril de 1882, en Nueva York, bajo la dirección de Rafael de Castro Palomino, quien solicita la colaboración del poeta. A partir del mes de marzo de 1883, el Maestro redacta “La América” en su totalidad, desde los titulares hasta los artículos ensayísticos. Martí caracteriza “La América” como “periódico útil”, pues se dedicó a divulgar los adelantos de la industria, comercio y agricultura de los productores de la América del Norte, y en el avisador prudente de los compradores de la América del Sur. Este carácter de la publicación permite a José Martí tratar desde las páginas de “La América” los recientes descubrimientos científicos, la reseña detallada de las exposiciones que exhibían los últimos logros de la t

Highlights: • We implemented a shared memory based interface of MARTe with EPICS. • We implemented an EPICS module supporting device and driver support. • We implemented an example EPICS IOC and CSS OPI for evaluation. - Abstract: The Multithreaded Application Real-Time executor (MARTe) is a multi-platform C++ middleware designed for the implementation of real-time control systems. It currently supports the Linux, Linux + RTAI, VxWorks, Solaris and MS Windows platforms. In the fusion community MARTe is being used at JET, COMPASS, ISTTOK, FTU and RFX in fusion [1]. The Experimental Physics and Industrial Control System (EPICS), a standard framework for the control systems in KSTAR and ITER, is a set of software tools and applications which provide a software infrastructure for use in building distributed control systems to operate devices. For a MARTe based application to cooperate with an EPICS based application, an interface layer between MARTe and EPICS is required. To solve this issue, a number of interfacing solutions have been proposed and some of them have been implemented. Nevertheless, a new approach is required to mitigate the functional limitations of existing solutions and to improve their performance for real-time applications. This paper describes the design and implementation of a shared memory based interface between MARTe and EPICS

Highlights: • We implemented a shared memory based interface of MARTe with EPICS. • We implemented an EPICS module supporting device and driver support. • We implemented an example EPICS IOC and CSS OPI for evaluation. - Abstract: The Multithreaded Application Real-Time executor (MARTe) is a multi-platform C++ middleware designed for the implementation of real-time control systems. It currently supports the Linux, Linux + RTAI, VxWorks, Solaris and MS Windows platforms. In the fusion community MARTe is being used at JET, COMPASS, ISTTOK, FTU and RFX in fusion [1]. The Experimental Physics and Industrial Control System (EPICS), a standard framework for the control systems in KSTAR and ITER, is a set of software tools and applications which provide a software infrastructure for use in building distributed control systems to operate devices. For a MARTe based application to cooperate with an EPICS based application, an interface layer between MARTe and EPICS is required. To solve this issue, a number of interfacing solutions have been proposed and some of them have been implemented. Nevertheless, a new approach is required to mitigate the functional limitations of existing solutions and to improve their performance for real-time applications. This paper describes the design and implementation of a shared memory based interface between MARTe and EPICS.

La historia orbital de Deimos y la oblicuidad de Marte

Science.gov (United States)

Brunini, A.; Yokoyama, T.

Recientemente, se ha demostrado mediante extensas integraciones numéricas, que la rotación de Marte pasó repetidamente por estados caóticos de movimiento, debido al pasaje por zonas de resonancia spin - órbita. En dichas circunstancias, la oblicuidad marciana pudo haber sufrido grandes excursiones de varias decenas de grados. Las consecuencias de dichas variaciones son de extrema importancia en el contexto de la búsqueda de manifestaciones de vida fósil en dicho planeta. El estudio de la dinámica orbital del satélite más exterior de Marte, Deimos, nos ha permitido comprobar, en el marco de las distintas teorías sobre su orígen, que la oblicuidad de Marte dificilmente pudo haber sufrido variaciones que la aparten más de 10o respecto de actual valor. Este resultado parece ser mucho más robusto que las simulaciones numéricas de Touma y Wisdom asi como las de Laskar y Robutel, lo que permite poner cotas más severas a la evolución paleoclimática de Marte.

We investigate a pool of international chess title holders born between 1901 and 1943. Using Elo ratings, we compute for every player his expected score in a game with a randomly selected player from the pool. We use this figure as the player's merit. We measure players' fame as the number of Google hits. The correlation between fame and merit is 0.38. At the same time, the correlation between the logarithm of fame and merit is 0.61. This suggests that fame grows exponentially with merit.

Validation by means of simulation is a crucial step when developing real-time control systems. Modeling and simulation are an essential tool since the early design phase, when the control algorithms are designed and tested. This phase is commonly carried out in off-line environments such as Matlab and Simulink. A MARTe-based simulator has been recently developed to validate the new JET Vertical Stabilization (VS) system. MARTe is the multi-thread framework used at JET to deploy hard real-time control systems. This paper presents the software architecture of the MARTe-based simulator and it shows how this tool has been effectively used to evaluate the effects of Edge Localized Modes (ELMs) on the VS system. By using the simulator it is possible to analyze different plasma configurations, extrapolating the limit of the new vertical amplifier in terms of the energy of the largest rejectable ELM.

Full Text Available Este trabajo expone y examina los cambios de percepción que experimentó José Martí sobre el papel de los pueblos originarios de América, entre 1875 y 1878, años en los que vivió en México y Guatemala, con intensa escala en Yucatán, lugares donde conoció directamente la cultura y el pueblo maya. Martí resume una visión inicial de nuestra América en la figura lítica de Chacmool cuando después de ser expropiada por el gobierno yucateco, el Apóstol cubano la admira en la ciudad de Mérida y expresa que es la síntesis de las culturas americanas. Aspecto poco estudiado en la obra de Martí es este acercamiento etnográfico a la realidad maya de Yucatán y Guatemala.   This paper aims at presenting and examining the change of perception José Martí underwent in relation to the role of the native peoples of America between 1875 and 1878, the years he lived in Mexico and Guatemala, during which he spent a large amount of time in Yucatan, where he was able to get to know the Mayan culture and its people first hand. Martí summarized his initial vision of our America in the lithic figure of Chacmool, which he was able to admire in the city of Merida, after it had been expropriated by the government of Yucatan. The Cuban apostle described this as a synthesis of American cultures. This ethnographic insight into the Mayan reality in Yucatan and Guatemala represents a scarcely explored aspect of Martí's work.

Figures of merit for surface plasmon waveguides

Science.gov (United States)

Berini, Pierre

2006-12-01

Three figures of merit are proposed as quality measures for surface plasmon waveguides. They are defined as benefit-to-cost ratios where the benefit is confinement and the cost is attenuation. Three different ways of measuring confinement are considered, leading to three figures of merit. One of the figures of merit is connected to the quality factor. The figures of merit were then used to assess and compare the wavelength response of hree popular 1-D surface plasmon waveguides: the single metal-dielectric interface, the metal slab bounded by dielectric and the dielectric slab bounded by metal. Closed form expressions are given for the figures of merit of the single metal-dielectric interface.

Merit exponents and control area diagrams in materials selection

International Nuclear Information System (INIS)

Zander, Johan; Sandstroem, Rolf

2011-01-01

Highlights: → Merit exponents are introduced to generalise the merit indices commonly used in materials selection. → The merit exponents can rank materials in general design situations. → To allow identification of the active merit exponent(s), control area diagrams are used. → Principles for generating the control area diagrams are presented. -- Abstract: Merit indices play a fundamental role in materials selection, since they enable ranking of materials. However, the conventional formulation of merit indices is associated with severe limitations. They are dependent on the explicit solution of the variables in the equations for the constraints from the design criteria. Furthermore, it is not always easy to determine which the controlling merit index is. To enable the ranking of materials in more general design cases, merit exponents are introduced as generalisations of the merit indices. Procedures are presented for how to compute the merit exponents numerically without having to solve equations algebraically. Merit exponents (and indices) are only valid in a certain range of property values. To simplify the identification of the controlling merit exponent, it is suggested that so called control area diagrams are used. These diagrams consist of a number of domains, each showing the active constraints and the controlling merit exponent. It is shown that the merit exponents play a crucial role when the control area diagram (CAD) is set up. The principles in the paper are developed for mechanically loaded components and are illustrated for engineering beams with two or three geometric variables.

Martí fue el organizador y líder de la última guerra americana contra el colonialismo europeo clásico, pero el sentido profundo que dio a esa lucha la convirtió en una verdadera guerra de liberación nacional: el primer movimiento concreto contra el imperialismo. Entre los rasgos más originales del pensamiento martiano están: la proclamación de la igualdad de razas; la búsqueda de la superación de las diferencias de clase mediante el equilibrio de las fuerzas sociales; la reivindicación de la solidaridad hacia los humildes como un deber; la predicación de una “guerra sin odios”, que debía ser obra del pueblo y no de líderes; la comprensión y definición de Nuestra América; la insistencia en la necesidad de una descolonización cultural latinoamericana; y el antiimperialismo.   This paper is a sketch of the Cuban writer and politician José Martí (1853-1895, with special attention to the validity of his ethical thinking, which is the basis of his permanent relevance.

Translational research typically requires data abstracted from medical records as well as data collected specifically for research. Unfortunately, many data within electronic health records are represented as text that is not amenable to aggregation for analyses. We present a scalable open source SQL Server Integration Services package, called Regextractor, for including regular expression parsers into a classic extract, transform, and load workflow. We have used Regextractor to abstract discrete data from textual reports from a number of 'machine generated' sources. To validate this package, we created a pulmonary function test data mart and analyzed the quality of the data mart versus manual chart review. Eleven variables from pulmonary function tests performed closest to the initial clinical evaluation date were studied for 100 randomly selected subjects with scleroderma. One research assistant manually reviewed, abstracted, and entered relevant data into a database. Correlation with data obtained from the automated pulmonary function test data mart within the Northwestern Medical Enterprise Data Warehouse was determined. There was a near perfect (99.5%) agreement between results generated from the Regextractor package and those obtained via manual chart abstraction. The pulmonary function test data mart has been used subsequently to monitor disease progression of patients in the Northwestern Scleroderma Registry. In addition to the pulmonary function test example presented in this manuscript, the Regextractor package has been used to create cardiac catheterization and echocardiography data marts. The Regextractor package was released as open source software in October 2009 and has been downloaded 552 times as of 6/1/2012. Collaboration between clinical researchers and biomedical informatics experts enabled the development and validation of a tool (Regextractor) to parse, abstract and assemble structured data from text data contained in the electronic health

Development of real-time applications is usually associated with nonportable code targeted at specific real-time operating systems. The boundary between hardware drivers, system services, and user code is commonly not well defined, making the development in the target host significantly difficult. The Multithreaded Application Real-Time executor (MARTe) is a framework built over a multiplatform library that allows the execution of the same code in different operating systems. The framework provides the high-level interfaces with hardware, external configuration programs, and user interfaces, assuring at the same time hard real-time performances. End-users of the framework are required to define and implement algorithms inside a well-defined block of software, named Generic Application Module (GAM), that is executed by the real-time scheduler. Each GAM is reconfigurable with a set of predefined configuration meta-parameters and interchanges information using a set of data pipes that are provided as inputs and required as output. Using these connections, different GAMs can be chained either in series or parallel. GAMs can be developed and debugged in a non-real-time system and, only once the robustness of the code and correctness of the algorithm are verified, deployed to the real-time system. The software also supplies a large set of utilities that greatly ease the interaction and debugging of a running system. Among the most useful are a highly efficient real-time logger, HTTP introspection of real-time objects, and HTTP remote configuration.

Full Text Available A. crassiflora Mart. a Brazilian savannah fruit, is a source of phytochemical compounds that possess a wide array of biological activities, including free radical scavenging. This native fruit proved to potentialize the mutagenic process in previous in vivo investigations. The aim of the present study was to investigate the effects of A. crassiflora Mart. pulp intake on colonic cell proliferation and on the development of Aberrant Crypt Foci (ACF in male Wistar rats. The animals were fed with either a commercial diet or a diet supplemented with A. crassiflora Mart. pulp mixed in 1%, 10% or 20% (w/w for 4 weeks or 20 weeks. The carcinogen 1,2-dimethylhydrazine dihydrochloride (4 doses, 40 mg kg-1 each was used to induce colonic ACF. After euthanasia, the blood, liver and colon samples were collected for biochemical determinations, oxidative stress or ACF development analysis, respectively. Immunohistochemical analyses of the colonic mucosa were performed using antibodies against proliferating cell nuclear antigen (PCNA in normal-appearing colonic crypt and β-catenin in ACF. There was no ACF development in the colon from groups treated with A. crassiflora Mart. pulp. Also, the biochemical and oxidative stress analysis, PCNA labeling and ACF development (number, multiplicity or cellular localization of β-catenin were unchanged as a result of marolo pulp intake. Thus, the present results suggest that A. crassiflora Mart. pulp intake did not exert any protective effect in the colon carcinogenesis induced by DMH in rats.

The diagnosis of melanoma metastatic to lymph node remains a difficult problem given its histological diversity. We examined the staining patterns of S-100, NK1/C3, HMB-45, and MART-1 (DC10) in melanoma metastases to lymph nodes. Immunohistochemical stains were performed on tissue sections of 126 formalin-fixed lymph nodes from 126 patients with an established diagnosis of metastatic melanoma. A total of 98% of cases (123 of 126) stained positive for S-100, 93% (117 of 125) stained positive for NK1/C3, 82% (103 of 126) stained positive for MART-1, and 76% (95 of 125) stained positive for HMB-45. The distribution and intensity of staining varied among these markers. A diffuse staining pattern, defined as >50% of tumor cells stained, was observed in 83% of MART-1-positive cases but in only 56% of S-100-positive cases, 48% of NK1/C3-positive cases, and 34% of HMB-45-positive cases. A maximally intense signal was almost always observed for MART-1 (83% of positive cases) but was rarely observed for NK1/C3 (20%). S-100 and HMB-45 showed maximally intense staining in 50% and 54% of cases, respectively. S-100 and NK1/C3 stained both histiocytes and melanocytes, whereas MART-1 and HMB-45 stained only melanocytes. Seventy-eight cases (63%) stained positive for all 4 markers, 17 cases (14%) stained for all markers except HMB-45, 13 cases (10%) stained for all markers except MART-1, 6 cases (5%) stained only with S-100 and NK1/C3, 4 cases (3%) stained only with S-100 and HMB-45, and 2 cases stained for all markers except S-100. One case each stained for the following: only S-100, only S-100 and HMB-45, and all markers except NK1/C3. One case exhibited absence of staining for any of these markers. We demonstrate that lymph node metastases of melanoma are heterogeneous with regard to tumor marker expression. S-100 and NK1/C3 were the most sensitive stains for detecting metastatic melanoma; however, they both also stain other nontumor cells in lymph nodes. MART-1 did not stain

2012-09-01

Full Text Available Abstract Background Translational research typically requires data abstracted from medical records as well as data collected specifically for research. Unfortunately, many data within electronic health records are represented as text that is not amenable to aggregation for analyses. We present a scalable open source SQL Server Integration Services package, called Regextractor, for including regular expression parsers into a classic extract, transform, and load workflow. We have used Regextractor to abstract discrete data from textual reports from a number of ‘machine generated’ sources. To validate this package, we created a pulmonary function test data mart and analyzed the quality of the data mart versus manual chart review. Methods Eleven variables from pulmonary function tests performed closest to the initial clinical evaluation date were studied for 100 randomly selected subjects with scleroderma. One research assistant manually reviewed, abstracted, and entered relevant data into a database. Correlation with data obtained from the automated pulmonary function test data mart within the Northwestern Medical Enterprise Data Warehouse was determined. Results There was a near perfect (99.5% agreement between results generated from the Regextractor package and those obtained via manual chart abstraction. The pulmonary function test data mart has been used subsequently to monitor disease progression of patients in the Northwestern Scleroderma Registry. In addition to the pulmonary function test example presented in this manuscript, the Regextractor package has been used to create cardiac catheterization and echocardiography data marts. The Regextractor package was released as open source software in October 2009 and has been downloaded 552 times as of 6/1/2012. Conclusions Collaboration between clinical researchers and biomedical informatics experts enabled the development and validation of a tool (Regextractor to parse, abstract and assemble

José Martí e a educação popular: um retorno às fontes José Martí and popular education: a return to the sources

Full Text Available Este artigo apresenta uma leitura de José Martí como fonte histórica da educação popular na América Latina. Parte-se do pressuposto de que não pode haver uma verdadeira refundamentação sem o retorno àquilo que sejam momentos, idéias ou princípios fundantes da educação popular. Após situar brevemente o pensamento e a obra de José Martí, caracteriza-se o conceito de educação popular como educação do povo, no sentido de educação universal. Num outro nível, busca-se identificar na obra de Martí traços da educação popular como um movimento político-pedagógico que se configura especialmente a partir da segunda metade do século passado. A premissa é que, num dado momento, educação do povo e educação popular deixam de ser termos equivalentes e que, em José Martí, temos elementos para pensar esses dois termos de forma dialética, num movimento de recriação de uma prática que, embora cindida pelas contingências históricas, é única. São identificados em sua obra quatro princípios da educação popular: a valorização da pluralidade de saberes; a relação interpessoal como ambiente para o aprender-ensinar e base para a transformação social; o conhecimento da realidade a partir de uma perspectiva emancipatória como ato político; e a educação como processo autoformativo da sociedade.This article presents José Martí as a historical source of popular education in Latin America. It starts from the assumption that there can be no true re-foundation without the return to those founding moments, ideas or principles of popular education. After giving a brief account of Martí's work and thought, we characterize the concept of popular education as education of the people, in the sense of a universal education. On a different level, we seek to identify in Martí's work elements of popular education as a political-pedagogical movement that takes shape especially since the latter half of the 20th century. The

Etnocentrismo, racismo y miedo: los indígenas y los incultos en Martí

Directory of Open Access Journals (Sweden)

Jorge Camacho

2010-04-01

Full Text Available In the following article I return to the idea of ethnicity and liberalism in Latin America during the last part of the 19th century. I also discuss Martí’s view of the Indians after 1885, when his chronicles were fueled by the rhetoric of pro-indigenous groups such as the Friends of Indians Association. I propose to look at other ways in which Martí’s ethnocentric view of culture and race intertwined with his agenda of “defending” the Indians, especially in his essay “Nuestra América.” For that purpose I retrace some of my previous arguments and discuss other essays that have recently elaborated on Martí’s “other side”, the one that imposes on the Indians his own liberal agenda, and the vision of modernity that the elites were constructing in Latin America at the end of 19th century. In my previous articles I discussed Martí’s chronicles on the Guatemalan, Mexican and American Indians and here I will focus on the similarities between the positivists in Mexico and Martí’s emphasis on “scientific politics” as well as his fear that those that were at the lowest level of society could one day revolt against the republic and destroy the justice “accumulated in books.” For books symbolized for Martí the “lettered elite”, those that had power and exercised it to their own advantage. He talked about this fear in Mexico, and in his most famous essay he returned to it again with a somewhat different perspective, but still with the conviction that within a democracy everything could be solved and a revolt from the “unlettered” masses was not justified. I argue that even if “Nuestra América” meant a more positive view of the “Indian problem”, Martí still considers the Indians, the “gauchos” and the rest of the “incultos” as a threat. They were the natural ally of the “caudillos” that ruled for so long Latin America, charismatic caudillos such as Juan Manuel de Rosas.

Ionizing radiation affects generation of MART-1-specific cytotoxic T cell responses by dendritic cells

International Nuclear Information System (INIS)

Liao, Y.P.; Wang, C.-C.; McBride, W.H.

Full text: The human MART-1/Melan-A (MART-1) melanoma tumor antigen is known to be recognized by cytotoxic T lymphocytes (CTLs) and several groups are using this target for clinical immunotherapy. Most approaches use dendritic cells (DCs) that are potent antigen presentation cells for initiating CTL responses. In order for CTL recognition to occur, DCs must display 9-residue antigenic peptides on MHC class I molecules. These peptides are generated by proteasome degradation and then transported through the endoplasmic reticulum to the cell surface where they stabilize MHC class I expression. Our previous data showed that irradiation inhibits proteasome function and, therefore, we hypothesized that irradiation may inhibit antigen processing and CTL activation, as has been shown for proteasome inhibitors. To study the importance of irradiation effects on DCs, we studied the generation MART-1-specific CTL responses. Preliminary data showed that irradiation of murine bone marrow derived DCs did not affect expression of MHC class I, II, CD80, or CD86, as assessed by flow cytometric analyses 24-hour after irradiation. The effect of irradiation on MART-1 antigen processing by DCs was evaluated using DC transduced with adenovirus MART-1 (AdVMART1). C57BL/6 mice were immunized with AdVMART1 transduced DCs, with and without prior irradiation. IFN-γ production was measured by ELISPOT assays after 10-14 days of immunization. Prior radiation treatment resulted in a significant decrease in MART-1-specific T cell responses. The ability of irradiated and non-irradiated AdVMART1/DC vaccines to protect mice against growth of murine B16 tumors, which endogenously express murine MART-1, was also examined. AdVMART1/DC vaccination protected C57BL/6 mice against challenge with viable B16 melanoma cells while DCs irradiated (10 Gy) prior to AdVMART1 transduction abrogated protection. These results suggest that proteasome inhibition in DCs by irradiation may be a possible pathway in

Among the relatively large number of known tumor-associated antigens (TAA) which are recognized by human CD8 T-cells, Melan-A/MART-1 is one of the most-if not the most-frequently used target for anti-cancer vaccines in HLA-A2 + melanoma patients. In this study, we analyzed the killing of a large...... panel of melanoma cells by a high avidity, MART-1-specific T-cell clone or a MART-1-specific, polyclonal T-cell culture. Strikingly, we observed that the MART-1-specific T-cells only killed around half of the analyzed melanoma cell lines. In contrast a Bcl-2-specific T-cell clone killed all melanoma...... cell lines, although the T-cell avidity of this clone was significantly lower. The MART-1-specific T-cell clone expressed NKG-2D and was fully capable of releasing both perforin and Granzyme B. Notably, the resistance to killing by the MART-1-specific T-cells could be overcome by pulsing...

Background: The characterization of the genes encoding melanoma-associated antigens MART-1 or gp100, recognized by T cells, has opened new possibilities for the development of immunization strategies for patients with metastatic melanoma. With the use of recombinant adenoviruses expressing either MART-1 or gp100 to immunize patients with metastatic melanoma, we evaluated the safety, immunologic, and potential therapeutic aspects of these immunizations. Methods: In phase I studies, 54 patients received escalating doses (between 107 and 1011 plaque-forming units) of recombinant adenovirus encoding either MART-1 or gp100 melanoma antigen administered either alone or followed by the administration of interleukin 2 (IL-2). The immunologic impact of these immunizations on the development of cellular and antibody reactivity was assayed. Results: Recombinant adenoviruses expressing MART-1 or gp100 were safely administered. One of 16 patients with metastatic melanoma receiving the recombinant adenovirus MART-1 alone experienced a complete response. Other patients achieved objective responses, but they had received IL-2 along with an adenovirus, and their responses could be attributed to the cytokine. Immunologic assays showed no consistent immunization to the MART-1 or gp100 transgenes expressed by the recombinant adenoviruses. High levels of neutralizing antibody were found in the pretreatment sera of the patients. Conclusions: High doses of recombinant adenoviruses could be safely administered to cancer patients. High levels of neutralizing antibody present in patients' sera prior to treatment may have impaired the ability of these viruses to immunize patients against melanoma antigens. PMID:9862627

Numerical Simulations to Assess ART and MART Performance for Ionospheric Tomography of Chapman Profiles.

Science.gov (United States)

Prol, Fabricio S; Camargo, Paulo O; Muella, Marcio T A H

2017-01-01

The incomplete geometrical coverage of the Global Navigation Satellite System (GNSS) makes the ionospheric tomographic system an ill-conditioned problem for ionospheric imaging. In order to detect the principal limitations of the ill-conditioned tomographic solutions, numerical simulations of the ionosphere are under constant investigation. In this paper, we show an investigation of the accuracy of Algebraic Reconstruction Technique (ART) and Multiplicative ART (MART) for performing tomographic reconstruction of Chapman profiles using a simulated optimum scenario of GNSS signals tracked by ground-based receivers. Chapman functions were used to represent the ionospheric morphology and a set of analyses was conducted to assess ART and MART performance for estimating the Total Electron Content (TEC) and parameters that describes the Chapman function. The results showed that MART performed better in the reconstruction of the electron density peak and ART gave a better representation for estimating TEC and the shape of the ionosphere. Since we used an optimum scenario of the GNSS signals, the analyses indicate the intrinsic problems that may occur with ART and MART to recover valuable information for many applications of Telecommunication, Spatial Geodesy and Space Weather.

The Multi-threaded Application Real-Time executor (MARTe) is a C++ framework that provides a development environment for the design and deployment of real-time applications, e.g. control systems. The kernel of MARTe comprises a set of data-driven independent blocks, connected using a shared bus. This modular design enforces a clear boundary between algorithms, hardware interaction and system configuration. The architecture, being multi-platform, facilitates the test and commissioning of new systems, enabling the execution of plant models in offline environments and with the hardware-in-the-loop, whilst also providing a set of non-intrusive introspection and logging facilities. Furthermore, applications can be developed in non real-time environments and deployed in a real-time operating system, using exactly the same code and configuration data. The framework is already being used in several fusion experiments, with control cycles ranging from 50 microseconds to 10 milliseconds exhibiting jitters of less than 2%, using VxWorks R , RTAI or Linux. Codes can also be developed and executed in Microsoft Windows R and Solaris R . This paper discusses the main design concepts of MARTe, in particular the architectural choices which enabled the combination of real-time accuracy, performance and robustness with complex and modular data driven applications.

Hebrew Hermeneutics and Inquisitorial Persecution: The Case of The Hebraist from Salamanca Martín Martínez de Cantalapiedra (XVI^th Century

Directory of Open Access Journals (Sweden)

Ricardo Muñoz Solla

2016-12-01

Full Text Available

Halfway through the 16th century in Spain the reading and interpretation of the Bible based on its original languages involved a very real danger for humanists who were seeking a better understanding of the Scriptures. The exclusive authority of the Latin Vulgate version declared by the Council of Trent in 1546 hindered the intellectual work of many Biblicists and Theologians, who were subjected to tight ideological control. In this context it must be considered the case of the Hebraist and scholar from the University of Salamanca, Martín Martínez de Cantalapiedra (1518-1579, who was prosecuted by the Inquisition of Valladolid in 1572 along with his colleagues Fray Luis de León and Gaspar de Grajal. All of them were accused of deviating from the genuine sense of the Vulgate in their more literal interpretations of the Masoretic text. The purpose of this article is to provide new evidence for the intellectual biography of Master Martínez de Cantalapiedra as well a to analyze the hermeneutical principles exposed during his inquisitorial in which he defended the Hebrew knowledge as an essential means of interpreting the Old Testament.

Pan, Jun; Huang, Haiguang; Liu, Yousong

A novel data mart based system for fishery rescue field was designed and implemented. The system runs ETL process to deal with original data from various databases and data warehouses, and then reorganized the data into the fishery rescue data mart. Next, online analytical processing (OLAP) are carried out and statistical reports are generated automatically. Particularly, quick configuration schemes are designed to configure query dimensions and OLAP data sets. The configuration file will be transformed into statistic interfaces automatically through a wizard-style process. The system provides various forms of reporting files, including crystal reports, flash graphical reports, and two-dimensional data grids. In addition, a wizard style interface was designed to guide users customizing inquiry processes, making it possible for nontechnical staffs to access customized reports. Characterized by quick configuration, safeness and flexibility, the system has been successfully applied in city fishery rescue department.

"Nuestra América": José Martí ante la Razón Moderna

Pedro Pablo Rodríguez

2015-09-01

Full Text Available Este artículo es un acercamiento al difícil y singular diálogo con el pensamiento moderno y sus procedimientos del escritor, pensador y político cubano José Martí. La tesis es que el ideario de Martí expresó los intereses y la perspectiva de los pueblos de Hispanoamérica, a la que llamó Nuestra América, por oposición, según escribió “a la otra América, que no es nuestra”. Plenamente consciente de que la identidad de la región se sustentaba en una cultura nueva, mestiza de lo aborigen y lo español, el cubano dedicó su ensayo “Nuestra América” a explicar los factores internos que mantenían las estructuras sociales, políticas y de pensamiento de la época colonial, así como el peligro que representaba el creciente poderío de Estados Unidos.   This article aims to approach Cuban writer, thinker and politician José Martí's harsh, singular dialogue with modern thinking and its procedures. It argues that Martí's set of ideas expressed the interests and viewpoint of the peoples of Hispanic America, which he called Our America, as opposed to, according to his own texts, "the other America, the one that is not ours". Fully conscious of the fact that the region's identity was based on a new culture, resulting from a mix of the indigenous and the Spanish, Martí used his essay "Our America" (originally, "Nuestra América" to explain the internal factors that maintained the colonial social, political and ideological structures, in addition to expressing the threat the growing power of the United States represented.

Performance Comparison of EPICS IOC and MARTe in a Hard Real-Time Control Application

Science.gov (United States)

Barbalace, Antonio; Manduchi, Gabriele; Neto, A.; De Tommasi, G.; Sartori, F.; Valcarcel, D. F.

2011-12-01

EPICS is used worldwide mostly for controlling accelerators and large experimental physics facilities. Although EPICS is well fit for the design and development of automation systems, which are typically VME or PLC-based systems, and for soft real-time systems, it may present several drawbacks when used to develop hard real-time systems/applications especially when general purpose operating systems as plain Linux are chosen. This is in particular true in fusion research devices typically employing several hard real-time systems, such as the magnetic control systems, that may require strict determinism, and high performance in terms of jitter and latency. Serious deterioration of important plasma parameters may happen otherwise, possibly leading to an abrupt termination of the plasma discharge. The MARTe framework has been recently developed to fulfill the demanding requirements for such real-time systems that are alike to run on general purpose operating systems, possibly integrated with the low-latency real-time preemption patches. MARTe has been adopted to develop a number of real-time systems in different Tokamaks. In this paper, we first summarize differences and similarities between EPICS IOC and MARTe. Then we report on a set of performance measurements executed on an x86 64 bit multicore machine running Linux with an IO control algorithm implemented in an EPICS IOC and in MARTe.

Full Text Available This article is an approach to the ideas of José Martí about the education, beginning from its function as formative of morals, ethics and esthetics values, and human and latin-american feelings. Also, it studies the popular character of the education like a human right, its scientist style and the urgency to use didactics methods for to stimulate the intelligence of students, without authoritarian and memorizing learning. This article insists in the important relations between the education and the societies and the epoch. The conclusion is: Cuban Revolution defined a strategy of development based in the ideas of José Martí. This strategy includes the education that, by the first time, takes into account the demands of our society.            

Young children consider merit when sharing resources with others.

Science.gov (United States)

Kanngiesser, Patricia; Warneken, Felix

2012-01-01

MERIT IS A KEY PRINCIPLE OF FAIRNESS: rewards should be distributed according to how much someone contributed to a task. Previous research suggests that children have an early ability to take merit into account in third-party situations but that merit-based sharing in first-party contexts does not emerge until school-age. Here we provide evidence that three- and five-year-old children already use merit to share resources with others, even when sharing is costly for the child. In Study 1, a child and a puppet-partner collected coins that were later exchanged for rewards. We varied the work-contribution of both partners by manipulating how many coins each partner collected. Children kept fewer stickers in trials in which they had contributed less than in trials in which they had contributed more than the partner, showing that they took merit into account. Few children, however, gave away more than half of the stickers when the partner had worked more. Study 2 confirmed that children related their own work-contribution to their partner's, rather than simply focusing on their own contribution. Taken together, these studies show that merit-based sharing is apparent in young children; however it remains constrained by a self-serving bias.

Full Text Available INTRODUÇÃO: A frequência cardíaca (FC no teste anaeróbio máximo de corrida (MART expressa o comportamento autonômico cardíaco em exercício. Ainda não foi investigado se tais respostas cronotrópicas apresentam associação com o desempenho aeróbio e anaeróbio. OBJETIVOS: Descrever a resposta cronotrópica cardíaca durante o MART nos segundos iniciais de estímulo (FC ON e de recuperação (FC OFF e estabelecer a associação entre as variáveis cronotrópicas com o desempenho aeróbio e anaeróbio. MÉTODOS: Foram voluntários 13 homens assintomáticos e fisicamente ativos, com 25,1 ± 4,9 anos, 76,8 ± 12,5 kg, 178,4 ± 9,0 cm e 50,6 ± 4,1 mL×kg‑1×min‑1. Na primeira visita, após a anamnese e medidas antropométricas, foi realizado um teste cardiopulmonar de exercício (TCPE com monitoração direta dos gases expirados. Na segunda visita, foi feita uma familiarização ao MART e na terceira, o teste de MART conduzido até a exaustão. RESULTADOS: A FC de recuperação (58 ± 20 bpm comparada à FC de pico alcançada no primeiro e no último estágio de MART (39 ± 14 bpm apresentou maior inclinação, resultando em maior amplitude de variação ao longo do teste, caracterizando diferenças significativas (P = 0,0017. A FC ON apresentou entre o momento inicial, meio e final do MART diferenças significativas (inicial versus final, p = 0,007. Para FC OFF foram encontradas diferenças significativas do início com o meio (p = 0,035 e do início com o final (p = 0,005 do teste. As correlações entre as variáveis cronotrópicas e de desempenho não apresentaram significância estatística (P < 0,05, assim como com as variáveis de desempenho. CONCLUSÃO: O MART parece ser um modelo de sobrecargas fisiológicas adequado para investigação da modulação autonômica cardíaca. Observou-se atuação do sistema parassimpático mesmo em cargas supramáximas até o final do teste.

Motion tracking-enhanced MART for tomographic PIV

International Nuclear Information System (INIS)

Novara, Matteo; Scarano, Fulvio; Batenburg, Kees Joost

2010-01-01

A novel technique to increase the accuracy of multiplicative algebraic reconstruction technique (MART) reconstruction from tomographic particle image velocimetry (PIV) recordings at higher seeding density than currently possible is presented. The motion tracking enhancement (MTE) method is based on the combined utilization of images from two or more exposures to enhance the reconstruction of individual intensity fields. The working principle is first introduced qualitatively, and the mathematical background is given that explains how the MART reconstruction can be improved on the basis of an improved first guess object obtained from the combination of non-simultaneous views reduced to the same time instant deforming the 3D objects by an estimate of the particle motion field. The performances of MTE are quantitatively evaluated by numerical simulation of the imaging, reconstruction and image correlation processes. The cases of two or more exposures obtained from time-resolved experiments are considered. The iterative application of MTE appears to significantly improve the reconstruction quality, first by decreasing the intensity of the ghost images and second, by increasing the intensity and the reconstruction precision for the actual particles. Based on computer simulations, the maximum imaged seeding density that can be dealt with is tripled with respect to the MART analysis applied to a single exposure. The analysis also illustrates that the maximum effect of the MTE method is comparable to that of doubling the number of cameras in the tomographic system. Experiments performed on a transitional jet at Re = 5000 apply the MTE method to double-frame recordings. The velocity measurement precision is increased for a system with fewer views (two or three cameras compared with four cameras). The ghost particles' intensity is also visibly reduced although to a lesser extent with respect to the computer simulations. The velocity and vorticity field obtained from a three

Previously, 19-Nor-2α-(3-hydroxypropyl-1α,25(OH2D3 (MART-10, the new brand 1α,25(OH2D3 analog, has been demonstrated to be an effective drug to inhibit HNSCC growth in vitro. Since most cancer patients die of metastasis, in this study, the antimetastatic effect of MART-10 on HNSCC was investigated. Our results reveal that both 1α,25(OH2D3 and MART-10 effectively repressed the migration and invasion of HNSCC cells, with MART-10 being much more potent than 1α,25(OH2D3. The antimetastatic effect of 1α,25(OH2D3 and MART-10 was mediated by attenuation of epithelial–mesenchymal transition (EMT, which was supported by the finding that the expression of EMT-inducing transcriptional factors, Sail and Twist, was inhibited by 1α,25(OH2D3 and MART

Keeping in mind the proposed FAST experiment and aiming to meet basic requirements such as a modular and distributed architecture, where different control subsystems can be easily integrated at different times, and can operate either independently or in cooperation with other subsystems, at the end of last year we planned to upgrade the architecture of the FTU real-time system, improving in such a way its flexibility and modularity. We decided to adopt an available packages to reach our goal: MARTe. We report on the state of the art of the MARTe migration process, the difficulties dealt with, the benefits and advantages achieved, the progress made from our last report and, in particular, we describe the integration of the ODIN equilibrium reconstruction system in the real-time environment. The ODIN algorithm was already coded in previous works, but its integration in the real-time system has never been carried out at FTU. We illustrate how the MARTe architecture and the RTNet level allows for a first level of parallelization, distributing the data and/or time among nodes.

Keeping in mind the proposed FAST experiment and aiming to meet basic requirements such as a modular and distributed architecture, where different control subsystems can be easily integrated at different times, and can operate either independently or in cooperation with other subsystems, at the end of last year we planned to upgrade the architecture of the FTU real-time system, improving in such a way its flexibility and modularity. We decided to adopt an available packages to reach our goal: MARTe. We report on the state of the art of the MARTe migration process, the difficulties dealt with, the benefits and advantages achieved, the progress made from our last report and, in particular, we describe the integration of the ODIN equilibrium reconstruction system in the real-time environment. The ODIN algorithm was already coded in previous works, but its integration in the real-time system has never been carried out at FTU. We illustrate how the MARTe architecture and the RTNet level allows for a first level of parallelization, distributing the data and/or time among nodes.

Highlights: • The paper describes the integration of two different frameworks for control and data acquisition. • It describes the way the two frameworks have been integrated. • It describes the advantages of this combined approach. • It presents a case study of the utilization of the two integrated frameworks. - Abstract: The recent long lasting fusion experiments introduced a change in paradigm for control and data acquisition. While formerly implemented by different systems, using different software and hardware solutions, new requirements, such as the need of handling a sustained data stream, the availability of powerful general-purpose computers and the evolution of Linux towards real-time responsiveness make an integrated solution nowadays feasible. In the fusion community several frameworks have been developed for control and data acquisition and some of them are shared among different experiments. In particular, MDSplus represents the most used framework for data acquisition and management and MARTe is a framework for real-time applications originally developed at JET, but then adopted in several other experiments. Neither system can be used alone to provide integrated real-time control and data acquisition but, since their functionality complements, they can be used in conjunction. To achieve this, an additional layer has been developed so that data handled in real-time by MARTe components can be redirected to pulse file for storage. At the same time, configuration data, typically defined in the MDSplus experiment model, can be seamlessly transferred to MARTe GAMs during system configuration.

Clinical track faculty: merits and issues.

Lee, Won-Hee; Kim, Cho Ja; Roh, Young Sook; Shin, Hyunsook; Kim, Mi Ja

2007-01-01

Clinical track faculty (CTF) has been in operation for more than two decades in the United States, and 12 of the top 20 schools of nursing with the highest National Institutes of Health funding in the United States have CTF in place. Yet, only limited articles have been published regarding the merits and issues related to its operation. This article examines the advantages/merits of establishing CTF in schools of nursing, discusses the qualification criteria and types of appointment for CTF, and analyzes issues related to operating CTF in Korea. A questionnaire survey and two workshops were conducted involving faculty from a college of nursing and clinical nurse managers from university-affiliated medical centers and community agencies. Most of the respondents indicated that establishing CTF was advantageous. Merits included the following: increasing reality-based clinical education and training; decreasing the reality shock of students; increasing student satisfaction; and linking education, practice, and research more effectively. Major issues were as follows: getting the approval of medical centers/universities; developing an agreement on CTF operation between the college of nursing and clinical agencies; clarifying types and criteria of appointment and promotion; and developing a statement on role and compensation policies. Most issues are similar to what U.S. schools of nursing have faced, except for the first one. In conclusion, establishing CTF in Korea appears to be highly desirable. Merits outweigh issues/concerns, and Korean nursing schools may look for an opportune time for obtaining the approval of medical centers/universities. Nursing schools in other countries that face a similar challenge of providing clinical teaching with high research performance may consider instituting CTF.

Wind energy and electricity prices. Exploring the 'merit order effect'

International Nuclear Information System (INIS)

Morthost, P.E.; Ray, S.; Munksgaard, J.; Sinner, A.F.

2010-04-01

This report focuses on the effect of wind energy on the electricity price in the power market. As the report will discuss, adding wind into the power mix has a significant influence on the resulting price of electricity, the so called merit order effect (MOE). The merit order effect has been quantified and discussed in many scientific publications. This report ends the first phase of a study on the MOE, evaluating the impact of EWEA's 2020 scenarios on future European electricity prices. The basic principles of the merit order effect are provided in the first part of the document. The literature review itself contains methods and tools not only to quantify the merit order effect but also in order to forecast its future range and volume.

Pedagogical Merit Review of Animal Use for Education in Canada.

Directory of Open Access Journals (Sweden)

Marc T Avey

Full Text Available There are two components to the review of animal based protocols in Canada: review for the merit of the study itself, and review of the ethical acceptability of the work. Despite the perceived importance for the quality assurance these reviews provide; there are few studies of the peer-based merit review system for animal-based protocols for research and education. Institutional animal care committees (ACCs generally rely on the external peer review of scientific merit for animal-based research. In contrast, peer review for animal based teaching/training is dependent on the review of pedagogical merit carried out by the ACC itself or another committee within the institution. The objective of this study was to evaluate the views of ACC members about current practices and policies as well as alternate policies for the review of animal based teaching/training. We conducted a national web-based survey of ACC members with both quantitative and qualitative response options. Responses from 167 ACC members indicated broad concerns about administrative burden despite strong support for both the current and alternate policies. Participants' comments focused mostly on the merit review process (54% relative to the efficiency (21%, impact (13%, and other (12% aspects of evaluation. Approximately half (49% of the comments were classified into emergent themes that focused on some type of burden: burden from additional pedagogical merit review (16%, a limited need for the review (12%, and a lack of resources (expertise 11%; people/money 10%. Participants indicated that the current system for pedagogical merit review is effective (60%; but most also indicated that there was at least some challenge (86% with the current peer review process. There was broad support for additional guidance on the justification, criteria, types of animal use, and objectives of pedagogical merit review. Participants also supported the ethical review and application of the Three Rs in

The merit of cogeneration: Measuring and rewarding performance

International Nuclear Information System (INIS)

Verbruggen, Aviel

2008-01-01

Cogeneration or combined heat and power (CHP) is a thermal power generation cycle with the merit of recovering part or all of the heat that is fatally discarded by such cycles. This merit of higher efficiency is subject of rewarding by public authorities. When the EU enacts CHP promotion in a Directive (1997-2004), crucial measurement and qualification issues remain unsolved. CEN (coordinator of the European Bureaus of Standards) contributes in clarifying the measurement of CHP activities, but shortfalls remain, while CEN bypasses the debate on qualifying CHP performance. This article offers appropriate methods for measuring CHP activities based on design characteristics of the plants. The co-generated electric output is a necessary and sufficient indicator of CHP merit and performance. Regulators can extend this indicator, but should avoid the perverse effects of biased external benchmarking as the EU Directive entails

Formal Verification Method for Configuration of Integrated Modular Avionics System Using MARTE

Directory of Open Access Journals (Sweden)

Lisong Wang

2018-01-01

Full Text Available The configuration information of Integrated Modular Avionics (IMA system includes almost all details of whole system architecture, which is used to configure the hardware interfaces, operating system, and interactions among applications to make an IMA system work correctly and reliably. It is very important to ensure the correctness and integrity of the configuration in the IMA system design phase. In this paper, we focus on modelling and verification of configuration information of IMA/ARINC653 system based on MARTE (Modelling and Analysis for Real-time and Embedded Systems. Firstly, we define semantic mapping from key concepts of configuration (such as modules, partitions, memory, process, and communications to components of MARTE element and propose a method for model transformation between XML-formatted configuration information and MARTE models. Then we present a formal verification framework for ARINC653 system configuration based on theorem proof techniques, including construction of corresponding REAL theorems according to the semantics of those key components of configuration information and formal verification of theorems for the properties of IMA, such as time constraints, spatial isolation, and health monitoring. After that, a special issue of schedulability analysis of ARINC653 system is studied. We design a hierarchical scheduling strategy with consideration of characters of the ARINC653 system, and a scheduling analyzer MAST-2 is used to implement hierarchical schedule analysis. Lastly, we design a prototype tool, called Configuration Checker for ARINC653 (CC653, and two case studies show that the methods proposed in this paper are feasible and efficient.

MARTe is a framework for the implementation of real-time systems, currently in use in several fusion experiments. MDSplus is a framework widely used in the fusion community for the management of data. The three systems provide a solution to different facets of the same process, that is, real-time plasma control development. Simulink diagrams will describe the algorithms used in control, which will be implemented as MARTe GAMs and which will use parameters read from and produce results written to MDSplus pulse files. The three systems have been integrated in order to provide a tool suitable to speed up the development of real-time control applications. In particular, it will be shown how from a Simulink diagram describing a given algorithm to be used in a control system, it is possible to generate in an automated way the corresponding MARTe and MDSplus components that can be assembled to implement the target system.

Literatura y filosofía: Sartre, Martín-Santos y Bartleby

Directory of Open Access Journals (Sweden)

Santamaría Pargada, Antonio

2006-04-01

Full Text Available Luis Martín Santos has been, after his soon death, one of the most unfairly forgotten Spanish intellectuals. This situation happens to be even more unjust considering the success of his novel “Time of Silence” and his unfinished “Time of Destruction”. The works of this psychiatrist, philosophically formed in the existentialism tradition, tackle from psychiatric and medical studies to interpretations of Dilthey, Jaspers and Heidegger. Maybe the most important achievement made by Dr. Martín-Santos was the fact of pooling in his novels all the different fields he worked in, namely: existential philosophy, psychiatry and literature. This mutual influence leads to a clearly existential interpretation of the narrative subject and to a nihilist conception of freedom: the nothingness completely understood as Sartre did. And, consequently, the attractiveness of approaching the Spanish author through literary theories that are close to the French contemporary philosophy and the primacy, not only of the existential analysis in literature, but also of the influence of the literary character as a fiction that is able to create possible realities. That is why it is interesting to study “Bartleby the Scrivener” as a paradoxical example of the existential nothingness made flesh. To put it in a nutshell, the existential triviality, a sign of modern times, has been indeed very successfully portrayed by Martín-Santos.Luis Martín-Santos ha sido, tras su temprana muerte, uno de los grandes olvidados entre los intelectuales españoles del franquismo. Olvido especialmente injusto, teniendo en cuenta el éxito de su novela Tiempo de Silencio y su interesante proyecto inacabado Tiempo de Destrucción. La obra de este psiquiatra formado filosóficamente en el existencialismo abarca desde trabajos psiquiátricos relativos a la medicina hasta interpretaciones de Dilthey, Jaspers y Heidegger. Tal vez el mayor logro de Martín- Santos fuera el de aunar en sus

Inconsciente genérico, feminismo y Nubosidad variable de Carmen Martín Gaite

Directory of Open Access Journals (Sweden)

Zecchi, Barbara

2006-08-01

Full Text Available In a context of marked tensions between gynocritics and contemporary Spanish women writers, Carmen Martín Gaite’s novel Nubosidad variable (Variable Cloud,1992 stands out as a curious paradox. As is well known, Martín Gaite repeatedly declared not to be a feminist and even scorned women who fought for equality between both sexes. This article argues that Nubosidad variable, however, constitutes one of the best examples of a consciously feminist text. In this novel Martín Gaite applies some of the most prominent paradigms of feminist literary theory, such as the construction of a non-linear and a-chronological narration (Julia Kristeva, the attempt to create a “language of the body” (Helène Cixous, the foregrounding of a mother-daughter bond (Luisa Muraro, as well as the use of female writing as a means of self-discovery (Elaine Showalter.En un contexto de falta de comunicación entre ginocrítica y escritura femenina, la novela Nubosidad variable (1992 de Carmen Martín Gaite se presenta como una significativa paradoja. Si por un lado su autora declaró repetidas veces no ser feminista —y hasta menospreció con ironía a las mujeres que han luchado por la igualdad—, Nubosidad variable es una innegable aplicación de algunos de los más conocidos paradigmas de la teoría literaria feminista. Desde la narración no-lineal y atemporal que sigue el “tiempo de las mujeres” de Julia Kristeva, hasta el intento de crear una lengua del cuerpo a lo Hélène Cixous; desde el vínculo madre-hija teorizado por Luisa Muraro, hasta la escritura femenina como auto-descubrimiento de Elaine Showalter, esta novela representa uno de los mejores ejemplos, dentro de la narrativa contemporánea española, de lo que llamaría un texto conscientemente feminista.

The effective communication methodology and influence of merit information on nuclear power

Oiso, Shinichi

2007-01-01

It was found by the survey the author carried out in 2005 that there is a possibility that even the person who opposes nuclear power generation may change his or her opinion after understanding the advantage of nuclear power. Then, how should merit information be transmitted? Is there a possibility that people feel repulsion after receiving merit information? What is the influence of providing merit information of nuclear power? Those kinds of questions were investigated in 2006. As a result, it was found that the use of magazine and NPO/NGO is effective. The utilization of all-night television broadcasting, iPod, energy environmental education in schools and science cafe have an effect too, especially for young generation. It was also found that 20% or less of the people feel repulsion for providing merit information of nuclear power. Concerning people's attitude towards nuclear power utilization, it was found that the number of those who support nuclear power generation tended to increase significantly by providing information depicting merits or benefits of nuclear power, however, it did not increase by explaining electric power companies' effort to promote nuclear power. Further more, concerning to the image of a nuclear power station site, it became clear that merit information of nuclear power provided positive effect for some items in explaining nuclear power generation.

Full Text Available Este artículo estudia los llamados Diarios del poeta José Lezama Lima, que recogen anotaciones suyas entre los años 1939-1949 y entre 1956-1958, para analizar cómo se refleja en ambos textos el interés por la poesía y la reflexión acerca de la misma. Sus anotaciones son comparadas con las de José Martí, percibiendo que mientras que la poesía era para Martí la forma suprema de la literatura, para Lezama llegó a ser un método de conocimiento de la realidad, la categoría central a la que conduce su pensamiento estético. Se pretende demostrar además cómo Lezama parte de las ideas de Martí sobre la poesía para llegar a tener ideas propias y luego trascendentes.   This article studies what are known as the Diaries of poet José Lezama Lima, in which his notes taken between 1939-1949 and 1956-1958 are gathered in order to analyze how both texts reflect his interest towards poetry as well as his reflections about it. His notes are compared with those of José Martí, revealing the fact that whereas for Martí, poetry was the supreme manifestation of literature; Lezama saw it as a method for acquiring knowledge of reality, the central category to which his aesthetic thinking leads. An attempt is made to further showcase the fact that Lezama starts off with Martí's ideas about poetry in order to later develop his own, which would at a later date become transcendental.

Impaired metacognition is associated with difficulties in the daily functioning of people with psychosis. Metacognition can be divided into four domains: Self-Reflection, Understanding the Other's Mind, Decentration, and Mastery. This study investigated whether Metacognitive Reflection and Insight Therapy (MERIT) can be used to improve metacognition. This study is a randomized controlled trial. Patients in the active condition (n = 35) received forty MERIT sessions, the control group (n = 35) received treatment as usual. Multilevel intention-to-treat and completers analyses were performed for metacognition and secondary outcomes (psychotic symptomatology, cognitive insight, Theory of Mind, empathy, depression, self-stigma, quality of life, social functioning, and work readiness). Eighteen out of 35 participants finished treatment, half the drop-out stemmed from therapist attrition (N = 5) or before the first session (N = 4). Intention-to-treat analysis demonstrated that in both groups metacognition improved between pre- and post-measurements, with no significant differences between the groups. Patients who received MERIT continued to improve, while the control group returned to baseline, leading to significant differences at follow-up. Completers analysis (18/35) showed improvements on the Metacognition Assessment Scale (MAS-A) scales Self Reflectivity and metacognitive Mastery at follow-up. No effects were found on secondary outcomes. On average, participants in the MERIT group were, based on MAS-A scores, at follow-up more likely to recognize their thoughts as changeable rather than as facts. MERIT might be useful for patients whose self-reflection is too limited to benefit from other therapies. Given how no changes were found in secondary measures, further research is needed. Limitations and suggestions for future research are discussed.

Management of asaí (Euterpe precatoria Mart. for fruit production in southern Colombian Amazonia

2014-06-01

Full Text Available The fruits of asaí (Euterpe precatoria Mart. are a traditional food for Amazonian inhabitants who harvest it from wild populations, employing management practices that affect palm populations and productivity. Here we present management data on fruit harvesting in a Tikuna community in the Colombian Amazon. We identified the market structure in Leticia and evaluated the population structure and fruit productivity in a scarcely harvested forest and a heavily harvested one. We performed interviews to determine management and market practices and we established plots to identify population structure and productivity. Harvesting is mostly for self-supply and palm felling is the main method. The fruits are mostly consumed and marketed as juice. The asaí market is small and seasonal but it represents an important source of income for many, mainly indigenous, families. The population density was 1 680 individuals and 248 adults/ha in San Martín de Amacayacu, where harvesting was from 2 % of all adult palms, and 916 individuals and 30 adults/ha in Leticia, where harvesting was from 23 % of all adult palms. The population structure in both sites followed an in-verted J-curve in which the majority of the individuals were seedlings. Productivity was 2.2 ton/ha/ year in San Martín de Amacayacu and 0.33 ton/ha/ year in Leticia. The population in Leticia is heavily harvested to supply the local market and the consequences of this use are a reduction in population density and fruit productivity and a low abundance of individuals in all size classes.

The purpose of this study was to describe the morphological aspect of Kielmeyera coriacea (“pau-santo” cork cells through its microscopic structure and to compare it with the cellular morphology of Quercus suber (cork oak, which is the main cork producing species worldwide. The bark from three trees of the species Kielmeyera coriacea Mart. was collected randomly at points 1.30 m above the ground, with four repetitions per sample. Samples came from native stands situated in the region of Luminárias - MG, Brazil. The study of morphological characteristics was conducted by counting the number of sides of the cells, and measuring the dimensions of the cells from images obtained by scanning electron microscopy (SEM. Images were analyzed using the LEOUIF software. The distribution in faces and edges of cork cells from Kielmeyera coriacea, was observed to have from 4 to 8 sides, with a predominance of hexagonal cells, similar to Quercus suber. The averages of height and thickness of the cell walls were 40 to 70 µm and 1.5 to 2.0 µm respectively, indicating cells from an early growth season. Both height and thickness were observed to be greater than those present in Quercus suber

We have investigated the thermoelectrical properties of chiral carbon nanotube and numerically evaluated the figure of merit. We observed that the properties are highly anisotropic and depend on the geometric chiral angle (GCA) θ h , temperature and the overlapping integrals (exchange energy) for the jumps along the tubular axis Δ z and the base helix Δ s . The thermopower α exhibited giant values with the peak occurring between 100 K and 150 K. The electron thermal conductivity showed unusually high value with the peaks shifting towards high temperature. We attribute the high peak values to electron-phonon interactions. Finally we noted that by changing the Δ s and Δ z it is possible to get a figure of merit greater than 1. (author)

The merit of synesthesia for consciousness research

Directory of Open Access Journals (Sweden)

Tessa Marije Van Leeuwen

2015-12-01

Full Text Available Synesthesia is a phenomenon in which additional perceptual experiences are elicited by sensory stimuli or cognitive concepts. Synesthetes possess a unique type of phenomenal experiences not directly triggered by sensory stimulation. Therefore, for better understanding of consciousness it is relevant to identify the mental and physiological processes that subserve synesthetic experience. In the present work we suggest several reasons why synesthesia has merit for research on consciousness. We first review the research on the dynamic and rapidly growing field of the studies of synesthesia. We particularly draw attention to the role of semantics in synesthesia, which is important for establishing synesthetic associations in the brain. We then propose that the interplay between semantics and sensory input in synesthesia can be helpful for the study of the neural correlates of consciousness, especially when making use of ambiguous stimuli for inducing synesthesia. Finally, synesthesia-related alterations of brain networks and functional connectivity can be of merit for the study of consciousness.

The coming electric Wal-Mart

International Nuclear Information System (INIS)

Drzemiecki, J.H.; Augustini, P.

1993-01-01

Market power in the competitive electric marketplace will depend on being a low-price leader. Electric utility executives are beginning to peer over the wall into the emerging world of competitive electric markets. Many will be terrified by the uncertainties and disorder associated with new service offerings such as retail wheeling and the transformation of other vestiges of the vertically integrated electric monopolies known for the past 100 years. The potential for increased competition for retail customers promises to have as fundamental an effect on the electric utility industry as Wal-Mart has had on retailing. Firms that are prepared for the new competitive environment will be in the strongest position to respond to the marketplace; those that are not prepared might want to consider the fate of the corner five-and-dime. To remain competitive, utility executives must take proactive steps to redefine their vision of their company's future. Such a redefinition must include a candid assessment of the strategies to be taken to reposition their firm to succeed, not just within the existing service area but in multiple markets

High figure-of-merit SOI power LDMOS for power integrated circuits

Directory of Open Access Journals (Sweden)

Yashvir Singh

2015-06-01

Full Text Available The structural modifications in the conventional power laterally diffused metal-oxide-semiconductor field-effect transistor (LDMOS are carried out to improve the breakdown voltage, on-resistance, gate-charge and figure-of-merits of the device with reduced cell pitch. The modified device has planer structure implemented on silicon-on-insulator which is suitable for low to medium voltage power integrated circuits. The proposed LDMOS consists of two gate electrodes placed vertically in two separate trenches build in the drift region and single source and drain contacts are taken on the top. The trench structure reduces the electric field inside the drift region and allow increased drift layer doping concentration leading to higher breakdown voltage, lower specific on-resistance, reduced gate-drain charge, and substantial improvement in the figure-of-merits. Using two-dimensional simulations, the performance of the proposed LDMOS is optimized and results are compared with the conventional LDMOS. Our simulation results show that the proposed device exhibits 110% higher breakdown voltage, 40% reduction in cell pitch, 19% lower specific on-resistance, 30% lower gate-to-drain charge leading to 5.5 times improvement in Baliga's figure-of-merit and 43% reduction in dynamic figure-of-merit over the conventional device.

Full Text Available José Martí otorgó a la educación un papel fundamental como elemento de transformación sociopolítica y económica en donde los métodos socráticos fueron reinventados para superar las metodologías conservadoras que acompañaban a la intelectualidad más reaccionaria. Para Martí, la educación debía estar encaminada a la liberación, pero basándose en el conocimiento y en la revalorización de la cultura y los valores latinoamericanos, y en manera alguna podía ser privilegio exclusivo de una clase.   José Martí gave to education a fundamental role as an element of socio-political and economic transformation, in which Socratic methods were reinvented to overcome conservative methodologies which were embedded in the most reactionary intellectuals. Therefore, this paper looks at his perspective over education. On the one hand, he argued it should be oriented towards liberation, but only insofar as it was based on the knowledge and appreciation of Latin American culture and values, and on the other, he highlighted that under no circumstances should it be an exclusive privilege of a social class.

Automated quantification of proliferation with automated hot-spot selection in phosphohistone H3/MART1 dual-stained stage I/II melanoma.

Nielsen, Patricia Switten; Riber-Hansen, Rikke; Schmidt, Henrik; Steiniche, Torben

2016-04-09

Staging of melanoma includes quantification of a proliferation index, i.e., presumed melanocytic mitoses of H&E stains are counted manually in hot spots. Yet, its reproducibility and prognostic impact increases by immunohistochemical dual staining for phosphohistone H3 (PHH3) and MART1, which also may enable fully automated quantification by image analysis. To ensure manageable workloads and repeatable measurements in modern pathology, the study aimed to present an automated quantification of proliferation with automated hot-spot selection in PHH3/MART1-stained melanomas. Formalin-fixed, paraffin-embedded tissue from 153 consecutive stage I/II melanoma patients was immunohistochemically dual-stained for PHH3 and MART1. Whole slide images were captured, and the number of PHH3/MART1-positive cells was manually and automatically counted in the global tumor area and in a manually and automatically selected hot spot, i.e., a fixed 1-mm(2) square. Bland-Altman plots and hypothesis tests compared manual and automated procedures, and the Cox proportional hazards model established their prognostic impact. The mean difference between manual and automated global counts was 2.9 cells/mm(2) (P = 0.0071) and 0.23 cells per hot spot (P = 0.96) for automated counts in manually and automatically selected hot spots. In 77 % of cases, manual and automated hot spots overlapped. Fully manual hot-spot counts yielded the highest prognostic performance with an adjusted hazard ratio of 5.5 (95 % CI, 1.3-24, P = 0.024) as opposed to 1.3 (95 % CI, 0.61-2.9, P = 0.47) for automated counts with automated hot spots. The automated index and automated hot-spot selection were highly correlated to their manual counterpart, but altogether their prognostic impact was noticeably reduced. Because correct recognition of only one PHH3/MART1-positive cell seems important, extremely high sensitivity and specificity of the algorithm is required for prognostic purposes. Thus, automated

The socioeconomic context of the use of Euterpe precatoria Mart. and E. oleracea Mart. in Bolivia and Peru.

Traditional knowledge (TK) has enabled communities to adapt to changes in life conditions over centuries. However, this local context is being dramatically affected by recent changes through globalization and modernization of societies. In this paper we seek to identify socio-economic factors that are related to the knowledge and use of two palm species in mestizo and indigenous communities in the Amazonian of Peru and Bolivia. Both species are known in the region under the main vernacular name of Asaí, and are source of two highly commercialized resources: palm-hearts and fruits. Euterpe precatoria Mart. is native to the region whereas E. oleracea Mart. is being introduced for the use of both resources. We compare TK about the two Euterpe species in both countries in relation to 14 socioeconomic factors in seven use categories. We performed a Multivariate analysis of variance (MANOVA) to elucidate the influence of each socioeconomic factor on the overall palm knowledge or on individual use categories. In the two countries, we found that mestizos, speaking only Spanish, and migrants in the same ecoregion, knew more uses in all use categories for E. precatoria than for E. oleracea, even in use categories such as Medicinal and veterinary and Construction, for which indigenous participants had more uses in case of other species. In Peru, the use of E. precatoria was higher among participants with greater wealth, which could be related to the commercial importance that both the fruits and the palm-hearts have had in the markets of the region. In contrast, in Bolivia, although some income generation from Euterpe sp. was observed, the use of E. precatoria was much more homogeneously distributed. The use of E. oleracea in Bolivia is recent, and although its most important uses are related to the consumption of fruits and palm-hearts (Human food), it is now being slowly used for Medicinal and Construction purposes, similar to E. precatoria. The use of each of the species

Gisely de Lima Oliveira

Full Text Available In this study, we aimed to determine lignified tissue in young stems of Struthanthus vulgaris Mart. by infrared microspectroscopy and histochemical methods as well as by fluorescence microscopy. Struthanthus vulgaris Mart. is a mistletoe species that belongs to the Loranthaceae family. A brief anatomical description was also carried out. The first procedure for analysis was to elaborate anatomical cross sections (20-30 µm from young stems before and after treatment with NaOH 1%. This procedure was applied to release possible low molecular mass phenolic compounds. Safranin-astra blue was used to distinguish anatomical tissues while Wiesner test enabled verification of lignified pericyclic fibers. Infrared microspectroscopy analysis confirmed the presence of lignin in this region according to the following spectral signals: 1600 (shoulder, 1511, 1453, 1338 and 1244 cm-1. Analyses of the cross section of young stems under fluorescence microscopy before and after treatment with NaOH 1% allowed us to confirm the presence of low mass phenolic compounds in the region of pericyclic fibers.

Una finestra sul passato: Irse de casa di Carmen Martín Gaite

Directory of Open Access Journals (Sweden)

Giulia Tosolini

2015-01-01

Full Text Available Beyond historical and social implications, migration represents the possibility of crossing a threshold and opening oneself up to new empirical and emotional spaces. Amparo, the main character of Carmen Martín Gaite’s Irse de casa (1998, is the perfect personification of the gaitian feminine canon. After leaving Spain and settling in New York, she became a successful fashion designer, and seemed happy and easy-going. The bond with memory and the past is the main topic of this novel, as it is in most of Martín Gaite’s production. The window on the past that Amparo closed moving to the US suddenly reappears when she needs to discover herself and her origins. This inconvenience in an anonymous life brings huge changes that will condition her and her loved ones. Travelling to Spain and interacting with places and people connected with her childhood, Amparo goes through the window she had closed forty years before, restoring the order. The window connects the present and the past, symbolizes the emigrant’s transience, personified in the novel by Amparo, who can definitely find the lost serenity and heart’s-ease.

Reactions to merit pay increases: a longitudinal test of a signal sensitivity perspective.

Shaw, Jason D; Duffy, Michelle K; Mitra, Atul; Lockhart, Daniel E; Bowler, Matthew

2003-06-01

The relationships among merit pay raises, trait positive affectivity (PA), and reactions to merit pay increases (pay attitudes and behavioral intentions) were explored in a longitudinal study of hospital employees. Drawing on signal sensitivity theory, the authors expected that PA would moderate the relationship between merit pay raise size and reactions to the increase such that pay raise size would be more strongly related to pay attitudes and behavioral intentions among those low in PA. Results strongly supported the predictions in the case of reactions to the raise amount (happiness and effort intentions) but not for pay level satisfaction. Implications of the results and directions for future research are identified.

Squitieri, Lee; Chung, Kevin C

2017-07-01

In 2017, the Centers for Medicare and Medicaid Services began requiring all eligible providers to participate in the Quality Payment Program or face financial reimbursement penalty. The Quality Payment Program outlines two paths for provider participation: the Merit-Based Incentive Payment System and Advanced Alternative Payment Models. For the first performance period beginning in January of 2017, the Centers for Medicare and Medicaid Services estimates that approximately 83 to 90 percent of eligible providers will not qualify for participation in an Advanced Alternative Payment Model and therefore must participate in the Merit-Based Incentive Payment System program. The Merit-Based Incentive Payment System path replaces existing quality-reporting programs and adds several new measures to evaluate providers using four categories of data: (1) quality, (2) cost/resource use, (3) improvement activities, and (4) advancing care information. These categories will be combined to calculate a weighted composite score for each provider or provider group. Composite Merit-Based Incentive Payment System scores based on 2017 performance data will be used to adjust reimbursed payment in 2019. In this article, the authors provide relevant background for understanding value-based provider performance measurement. The authors also discuss Merit-Based Incentive Payment System reporting requirements and scoring methodology to provide plastic surgeons with the necessary information to critically evaluate their own practice capabilities in the context of current performance metrics under the Quality Payment Program.

A psychology of liberation for Central America: the unfinished work of Ignacio Martín-Baró (1942-1989).

Gondra, José María

2013-01-01

On November 16, 1989 the world was shocked by the news of the assassination of six Jesuits at the campus of the Universidad Centro Americana José Simeón Cañas (UCA) in San Salvador, El Salvador. Among those murdered by government soldiers was Ignacio Martín-Baró, a PhD in social psychology from the University of Chicago who at that time was the Vice-Rector for Academic Affairs and Vice-President of the Interamerican Society of Psychology (SIP). Drawing on Martín-Baró's published writings and non-published academic papers and correspondence, this article traces the evolution of the Spanish-born Jesuit who became a leading authority among Latin American social psychologists. In particular, it analyzes his project of becoming a clinical psychologist under the influence of psychoanalysis, his critical social psychology aimed to "de-ideologize" the oppressed social classes of El Salvador, and his ultimate project of a psychology of liberation for Latin America. Martín-Baró's work came to a tragic end just when it began to bear fruit, but it stands as a testimony to a lifetime committed to the human values of democracy, social justice and service to society's poorest and most neglected.

La conmemoración de las Independencias hispanoamericanas en José Martí: El intelectual moderno y la guerra

Directory of Open Access Journals (Sweden)

Susana Emilce Zanetti

2010-11-01

Full Text Available Bolívar, San Martin and Páez are the only Independence protagonists to whom Martí devotes his celebratory speeches and chronicles. Those texts were published throughout a decade [from 1883 to 1894], exactly when Latin American political and cultural leaders regard themselves as having the right to establish [not without dispute] those "places of memory" [in the sense of Nora 2003] which monumentalize a recent heroic history. The texts by Martí are interesting in this sense: facing the imminent fight for the independence of Cuba, his evocation of past heroic deeds acquires a special symbolic value. It assumes the return to a finished era but from which ethical, social and political key values for the present must be extracted. Martí encourages the cult of the heroes but, at the same time, he imposes specific and divergent meanings. He celebrates the heroic deed but also emphasizes the bond between the leaders and the people, by pointing out the authority of both of them in materializing independency and the exclusion of the latter from the processes of modernization. And also, in his assessment, he warns about the errors of the leaders linked to the 'blindness of power'

We investigate the figure of merit of a quantum dot (QD) system irradiated with an external microwave filed by nonequilibrium Green's function (NGF) technique. Results show that the frequency of microwave field influence the figure of merit ZT significantly. At low temperature, a sharp peak can be observed in the figure of merit ZT as the frequency of ac field increases. As the frequency varies, several zero points and resonant peaks emerge in the figure of merit ZT. By adjusting the frequency of the microwave field, we can obtain high ZT. The figure of merit ZT increases with the decreasing of linewidth function Γ. In addition, Wiedemann–Franz law does not hold, particularly in the low frequency region due to multi-photon emission and absorption. Some novel thermoelectric properties are also found in two-level QD system.

Full Text Available José Martí proposes that for the proper development of the Republic in America it is essential to secure a government that has as the premises of its administration the natural categories of its origin. To evaluate the local characteristics Martí was thinking of I will carry out an analysis of two of his essays: Nuestra América (Martí, 1977 and Coney Island (Martí, 1881, in an attempt to unravel the polarisation strategy which supports his argument. Indeed, through a semantic axis the author places the concepts of nature and interiority over external and foreign, making a parallel between what he calls “natural men in America” and those who represent the “other”, the people of the United States. In this way, it will be possible to see how Martí will question the alleged hegemony of the northern country, claiming the primitive qualities of American indigenous peoples, to condition the problem of allocation of barbarism. The main theoretical framework to address this work is the use of the theories of discourse analysis of Teun van Dijk, which will serve me to develop and analyse the semantic axis that Martí creates in the works studied.José Martí propone que para el buen desarrollo de la República en América es indispensable un gobierno que fije como premisas para su administración las categorías naturales y autóctonas de su origen. Para apreciar cuáles son las características locales pensadas por Martí llevaré a cabo un análisis de dos de sus ensayos: Nuestra América (Martí, 1977 y Coney Island (Martí, 1881, con la intención de desentrañar la estrategia de polarización que da sustento a su argumentación. En efecto, el autor a través de un eje semántico sitúa los conceptos de naturaleza e interioridad por sobre lo externo y lo foráneo, realizando un paralelo entre lo que él llama “los hombres naturales de América” y aquellos que representarían a los “otros”, es decir a los habitantes de los

Luciene Toledo Almeida

2017-02-01

Full Text Available Este trabalho utiliza um método de processamento digital de imagens para detecção de feições eólicas na superfície de Marte.  Essas feições são rastros de vórtices convectivos recorrentes em Marte, estes, por sua vez, são formados por correntes de ar quente instáveis, próximas à superfície, provocadas por insolação. A área de estudo escolhida foi Thaumasia. O método aplicado baseia-se na teoria da Morfologia Matemática, sendo os rastros obtidos de maneira automática via processamento digital de imagens e binarização automática pelo método de otsu restrito. Os rastros foram detectados automaticamente nas imagens orbitais, o que permitiu calcular características importantes dos vórtices como: largura média e máxima, área de recobrimento, direção preponderante entre outros. Os resultados podem ser usados para auxiliar na compreensão do fenômeno que ocorre no ambiente marciano, contribuindo para o entendimento de como os vórtices de dust devils podem influenciar nas variações locais climáticas do planeta e se faz importante por ser o processo geológico em maior atividade no planeta.

An analysis of natural ventilation techniques to achieve indoor comfort in Wal-Mart express

Science.gov (United States)

O'Dea, Shona

Despite global efforts to reduce world fossil fuel dependency the world still obtains 81% of its energy from fossil fuels (IEA,2009). Modern renewable alternatives have been around since the mid twentieth century these alternatives have not been integrated into electrical grid systems at the exponential rate required to eradicate fossil fuels dependency. The problem, world energy demand, is too large to be satisfied by anything other than the energy-dense fossil fuels used today. We must change our energy intensive processes in order to conserve energy and hence reduce the demands that alternatives must satisfy. This research aims to identify sustainable design opportunities through the application of innovative technologies for the largest retailer in the US with the view that a viable conservative design measure could be applied to the store model, which is replicated across the country, causing a cumulative and hence larger impact on the company energy consumption as a whole. This paper will present the literature available on the 'big box' industry and Wal-Mart, comfort, natural ventilation and building simulation software and then perform an analysis into the viability of naturally ventilating the Wal-Mart Express sales zone using Monodraught natural ventilation windcatcher products

Heterogeneity of Metastatic Melanoma:  Correlation of MITF With Its Transcriptional Targets MLSN1, PEDF, HMB-45, and MART-1.

Zand, Sarvenaz; Buzney, Elizabeth; Duncan, Lyn M; Dadras, Soheil S

2016-09-01

Histologic and molecular heterogeneity is well recognized in malignant melanoma; however, the diversity of expression of new and classic melanoma markers has not been correlated in serial sections of metastases. We examined and correlated the expression of microphthalmia transcription factor (MITF) with its transcriptional targets, including melastatin (MLSN1/TRPM1), pigment epithelium-derived factor (SERPINF1/PEDF), SILV/PMEL17/GP100 (human melanoma black 45 [HMB-45]), and melanoma antigen recognized by T cells 1 (MART-1)/MLANA, in 13 melanoma metastases in lymph nodes of 13 patients. The expression levels and patterns of marker expression were recorded by a semiquantitative, 4-point ordinal reactivity method. Our results showed a consistently robust and diffuse expression of MITF protein in 12 (92%) of 13 metastatic tumors compared with variable expression of MLSN1 (46%) messenger RNA or PEDF (75%), HMB-45 (54%), and MART-1 (46%) proteins. Overall, in melanoma lymph node metastases, MITF protein expression was not tightly correlated with its gene targets. Moreover, the immunoreactivity for MITF, compared with MART-1 and HMB-45, was retained, supporting immunohistochemical detection of MITF as a more sensitive method of detecting metastatic melanoma. © American Society for Clinical Pathology, 2016.

Little is known about the practices for stocking and procuring healthy food in non-traditional food retailers (e.g., gas-marts, pharmacies). The present study aimed to: (i) compare availability of healthy food items across small food store types; and (ii) examine owner/manager perceptions and stocking practices for healthy food across store types. Descriptive analyses were conducted among corner/small grocery stores, gas-marts, pharmacies and dollar stores. Data from store inventories were used to examine availability of twelve healthy food types and an overall healthy food supply score. Interviews with managers assessed stocking practices and profitability. Small stores in Minneapolis and St. Paul, MN, USA, not participating in the Special Supplemental Nutrition Program for Women, Infants, and Children. One hundred and nineteen small food retailers and seventy-one store managers. Availability of specific items varied across store type. Only corner/small grocery stores commonly sold fresh vegetables (63% v. 8% of gas-marts, 0% of dollar stores and 23% of pharmacies). More than half of managers stocking produce relied on cash-and-carry practices to stock fresh fruit (53%) and vegetables (55%), instead of direct store delivery. Most healthy foods were perceived by managers to have at least average profitability. Interventions to improve healthy food offerings in small stores should consider the diverse environments, stocking practices and supply mechanisms of small stores, particularly non-traditional food retailers. Improvements may require technical support, customer engagement and innovative distribution practices.

Half-metallic perovskite superlattices with colossal thermoelectric figure of merit

KAUST Repository

Upadhyay Kahaly, M.; Ozdogan, K.; Schwingenschlö gl, Udo

2013-01-01

Nowadays heavy experimental efforts are focussed on doped oxide thermoelectrics to increase the thermopower and thermoelectric performance. We propose a high thermoelectric figure of merit for half-metallic SrTi1−xCoxO3 (x = 0, 0.125, 0.25, 0.375, and 0.5) in a superlattice with SrTiO3, which is stable at high temperatures and in an oxygen environment. The maximal value of Z hardly depends on the doping, while the temperature at which the maximum occurs increases with the Co concentration. The easy tunability from being an insulator to a half-metal under substitutional doping combined with the colossal figure of merit opens up great potential in the emerging field of spin-caloritronics.

eSciMart: Web Platform for Scientific Software Marketplace

Science.gov (United States)

Kryukov, A. P.; Demichev, A. P.

2016-10-01

In this paper we suggest a design of a web marketplace where users of scientific application software and databases, presented in the form of web services, as well as their providers will have presence simultaneously. The model, which will be the basis for the web marketplace is close to the customer-to-customer (C2C) model, which has been successfully used, for example, on the auction sites such as eBay (ebay.com). Unlike the classical model of C2C the suggested marketplace focuses on application software in the form of web services, and standardization of API through which application software will be integrated into the web marketplace. A prototype of such a platform, entitled eSciMart, is currently being developed at SINP MSU.

José Martí e los indios de Norteamérica: mediazione culturale e «scontro di civiltà». Una rilettura critica

Directory of Open Access Journals (Sweden)

Alessandro Badella

2010-01-01

Full Text Available The Cuban poet José Martí, “Master of the Americas” as pointed out by a famous Italian study by Carlo Batà, was probably the most important South American thinker of the two last decades of the Nineteenth century. This essay deals with the importance of “civilization clash” between US positivism - or WASP-ism - and the last resistances of Native Americans' cultural heritage during his personal experience as an exile in the United States. Martí, in this racial struggle and racist instincts, experienced a dual vision about the “Indian problem” in the Americas. In his first essays he focused on the positivistic view, really common among Latin American cultural élites (from Alberdi to Sarmiento, which depicted the Indian people as the burden of creole and white race in the path toward progress.On the other hand, as appeared clearly in Escenas americanas, the Cuban analysed more precisely the American struggle between civilization and savagery. In the cultural massacre inflicted to Indian tribes, he saw the real savagery in American civilization. So, this reflection paved the way to a new approach in considering the possibility of importing the Anglo-saxon model of civilization and political structures to the liberated Cuba after the independence (but also to continental Latin America.This relationship let us understand some interesting features in Martí's huge cultural production. We are introduced to the very essence of his cultural mediation between those two different lifestyles and models of civilization. This mediation would have represented a new way of intending North vs South America struggles or even Western way of life vs different ones, considered “barbarous” from the first.In our modern times, in which the terms “exporting values” or “civilization clash” seem to be very common in usage, it is really stimulating discover that the same problem was posed by Martí more than one century ago.

Short communication: Genetic lag represents commercial herd genetic merit more accurately than the 4-path selection model.

Science.gov (United States)

Dechow, C D; Rogers, G W

2018-05-01

Expectation of genetic merit in commercial dairy herds is routinely estimated using a 4-path genetic selection model that was derived for a closed population, but commercial herds using artificial insemination sires are not closed. The 4-path model also predicts a higher rate of genetic progress in elite herds that provide artificial insemination sires than in commercial herds that use such sires, which counters other theoretical assumptions and observations of realized genetic responses. The aim of this work is to clarify whether genetic merit in commercial herds is more accurately reflected under the assumptions of the 4-path genetic response formula or by a genetic lag formula. We demonstrate by tracing the transmission of genetic merit from parents to offspring that the rate of genetic progress in commercial dairy farms is expected to be the same as that in the genetic nucleus. The lag in genetic merit between the nucleus and commercial farms is a function of sire and dam generation interval, the rate of genetic progress in elite artificial insemination herds, and genetic merit of sires and dams. To predict how strategies such as the use of young versus daughter-proven sires, culling heifers following genomic testing, or selective use of sexed semen will alter genetic merit in commercial herds, genetic merit expectations for commercial herds should be modeled using genetic lag expectations.

Universal Curve of Optimum Thermoelectric Figures of Merit for Bulk and Low-Dimensional Semiconductors

Science.gov (United States)

Hung, Nguyen T.; Nugraha, Ahmad R. T.; Saito, Riichiro

2018-02-01

This paper is a contribution to the Physical Review Applied collection in memory of Mildred S. Dresselhaus. Analytical formulas for thermoelectric figures of merit and power factors are derived based on the one-band model. We find that there is a direct relationship between the optimum figures of merit and the optimum power factors of semiconductors despite of the fact that the two quantities are generally given by different values of chemical potentials. By introducing a dimensionless parameter consisting of the optimum power factor and lattice thermal conductivity (without electronic thermal conductivity), it is possible to unify optimum figures of merit of both bulk and low-dimensional semiconductors into a single universal curve that covers many materials with different dimensionalities.

The recent identification of genes encoding melanoma-associated antigens has opened new possibilities for the development of cancer vaccines designed to cause the rejection of established tumors. To develop a syngeneic animal model for evaluating antigen-specific vaccines in cancer therapy, the murine homologues of the human melanoma antigens MART1 and gp 100, which were specifically recognized by tumor-infiltrating lymphocytes from patients with melanoma, were cloned and sequenced from a murine B16 melanoma cDNA library. The open reading frames of murine MART1 and gp 100 encode proteins of 113- and 626-amino acids with 68.8 and 77% identity to the respective human proteins. Comparison of the DNA sequences of the murine MART1 genes, derived from normal melanocytes, the immortalized nontumorgenic melanocyte line Melan-a and the B16 melanoma, showed all to be identical. Northern and Western blot analyses confirmed that both genes encoded products that were melanocyte lineage proteins. Mice immunized with murine MART1 or gp 100 using recombinant vaccinia virus failed to produce any detectable T-cell responses or protective immunity against B16 melanoma. In contrast, immunization of mice with human gp 100 using recombinant adenoviruses elicited T cells specific for hgp100, but these T cells also cross reacted with B16 tumor in vitro and induced significant but weak protection against B16 challenge. Immunization with human and mouse gp100 together [adenovirus type 2 (Ad2)-hep100 plus recombinant vaccinia virus (rVV)-mgp100], or immunization with human gp100 (Ad2-hgp100) and boosting with heterologous vector (rVV-hgp100 or rVV-mgp100) or homologous vector (Ad2-hgp100), did not significantly enhance the protective response against B16 melanoma. These results may suggest that immunization with heterologous tumor antigen, rather than self, may be more effective as an immunotherapeutic reagent in designing antigen-specific cancer vaccines.

Epistemic merit, autonomy, and testimony

Directory of Open Access Journals (Sweden)

Jesús VEGA ENCABO

2008-01-01

Full Text Available In this paper, it is argued that both the informer and the hearer in a testimonial situation deserve epistemic merit insofar as they contribute to the collaborative achievement of sharing knowledge. The paper introduces a distinction between the ideals of self-sufficiency and epistemic autonomy. The autonomous exercise of our epistemic agency is very often carried out under strong conditions of epistemic dependence. Testimony exhibits a kind of social dependence that does not threaten the autonomy of the subjects that need to consider their own epistemic capacities. When involved in a testimonial situation, both speaker and hearer declare, at least implicitly, the standings they occupy in an epistemic space and are obliged to recognise certain epistemic requirements.

Distributions of radioactivity and natural radionuclides in water, sediment and eichornia crassipes (mart) solms from Surabaya River and coastal area have been evaluated. Five sampling locations were selected to represent fresh water and coastal water environment. The samples consist of water (fresh & coastal), bottom surface sediment and eichornia crassipes (mart) solms. The result showed that the gross-β activity from water environment were lower than the threshold value of Environmental Minister Act. Kep.02/MENKLH/I/1988 (1000 mBq/L) and indicated that β-radio ecological quality of water were still good. But the activity of the gross-α of water environment were higher than the threshold value of Environmental Minister Act. Kep.02/MENKLH/I/1988 (100 mBq/L). The eichornia crassipes (mart) solms (gross) activity were higher than water and sediment activities and indicated that transfer of radio nuclides from water to sediment and organism can be detected in water environment. Two natural radionuclide can be identified by γ-Spectrometric technique, they were K"4"0 and Tl"2"0"8. Generally the distribution factors F_D were smaller than bioaccumulation factor F_B. (author)

Decoction of roots of the Amazonian palm acai (Euterpe precatoria Mart.) is widely used by Brazilian and Peruvian people as an anti-inflammatory, to heal kidney and liver diseases and against snake bites. In this study, the antioxidant activity of extracts and flavonoids (quercetin, catechin, epicatechin, rutin and astilbin) isolated from roots and leaf stalks of E. precatoria was investigated using β-carotene in TLC plates and DPPH radical scavenging in a spectrophotometric bioassay. All extracts and flavonoids showed activity. Also, the cytotoxic activity of these extracts was evaluated by the brine shrimp (Artemia salina) larvicide bioassay and was lower than that of lapachol, used as control. The presence of flavonoids and sitosterol-3-O-β-D-glucopyranoside in the extracts can justify the use of the plant in traditional medicine. (author)

The philologist Pedro Martínez López: an imaginative liberal lampoonist | El filólogo Pedro Martínez López: un libelista liberal imaginativo

Full Text Available In 1830, the philologist Pedro Martínez López was forced to go into exile in France for political reasons. In 1832, he published Representación a Fernando VII, rey de España, a lampoon in which he made a whole string of accusations against the tyrant. At the end of the following year, he published España en 1833, al expirar Fernando VII, another lampoon in which he blamed the king's despotic reign for the country's disastrous situation and asserted that such abuses and injustices could only be remedied by re-establishing the Constitution of Cádiz of 1812. In 1834, he ceased to rail against his political enemies, changed strategy, and using his considerable imagination, wrote a kind of fable entitled Una noche en el infierno, vista entre sueños. With a mixture of humour and acid wit, it told of how all the devils in the Kingdom of Darkness, embracing the «sacred» cause of liberalism, vented their anger on the deceased Ferdinand and his followers, who were still in power. It would appear that the work was a success, since it was republished in 1836. In 1835, disillusioned with the tepid and conservative liberal regime of the Estatuto Real, Martínez López wrote another story, Las Brujas en Zugarramurdi, in which different satanic creatures, this time sorceresses, take it upon themselves to defeat moderantismo and establish a progressive regime. After this, he ceased to publish lampoons and political parables and devoted himself to producing learned works, bringing out various dictionaries and grammars which were republished several times. | En 1830, el filólogo Pedro Martínez López tuvo que exiliarse a Francia por motivos políticos.

A field prototype of an antibody array-based life-detector instrument, Signs Of LIfe Detector (SOLID2), has been tested in a Mars drilling mission simulation called MARTE (Mars Astrobiology Research and Technology Experiment). As one of the analytical instruments on the MARTE robotic drilling rig, SOLID2 performed automatic sample processing and analysis of ground core samples (0.5 g) with protein microarrays that contained 157 different antibodies. Core samples from different depths (down to 5.5 m) were analyzed, and positive reactions were obtained in antibodies raised against the Gram-negative bacterium Leptospirillum ferrooxidans, a species of the genus Acidithiobacillus (both common microorganisms in the Río Tinto area), and extracts from biofilms and other natural samples from the Río Tinto area. These positive reactions were absent when the samples were previously subjected to a high-temperature treatment, which indicates the biological origin and structural dependency of the antibody-antigen reactions. We conclude that an antibody array-based life-detector instrument like SOLID2 can detect complex biological material, and it should be considered as a potential analytical instrument for future planetary missions that search for life.

Historical biogeography sets the foundation for contemporary conservation of martens (genus Martes) in northwestern North America

2017-01-01

Effective conservation of insular populations requires careful consideration of biogeography, including colonization histories and patterns of endemism. Across the Pacific Northwest of North America, Pacific martens (Martes caurina) and American pine martens (Martes americana) are parapatric sister species with distinctive postglacial histories. Using mitochondrial DNA and 12 nuclear microsatellite loci, we examine processes of island colonization and anthropogenic introductions across 25 populations of martens. Along the North Pacific Coast (NPC), M. caurina is now found on only 2 islands, whereas M. americana occurs on mainland Alaska and British Columbia and multiple associated islands. Island populations of M. caurina have a longer history of isolation reflected in divergent haplotypes, private microsatellite alleles, and relatively low within-population diversity. In contrast, insular M. americanahave lower among-population divergence and higher metrics of within-population diversity. On some NPC islands, introductions of M. americana may be related to decline of M. caurina. Long-term persistence of these species likely has been influenced by anthropogenic manipulations, including wildlife translocations and industrial-scale deforestation, yet, the distinctive histories of these martens have not been incorporated into natural resource policies.

An empirically derived figure of merit for the quality of overall task performance

Science.gov (United States)

Lemay, Moira

1989-01-01

The need to develop an operationally relevant figure of merit for the quality of performance of a complex system such as an aircraft cockpit stems from a hypothesized dissociation between measures of performance and those of workload. Performance can be measured in terms of time, errors, or a combination of these. In most tasks performed by expert operators, errors are relatively rare and often corrected in time to avoid consequences. Moreover, perfect performance is seldom necessary to accomplish a particular task. Moreover, how well an expert performs a complex task consisting of a series of discrete cognitive tasks superimposed on a continuous task, such as flying an aircraft, does not depend on how well each discrete task is performed, but on their smooth sequencing. This makes the amount of time spent on each subtask of paramount importance in measuring overall performance, since smooth sequencing requires a minimum amount of time spent on each task. Quality consists in getting tasks done within a crucial time interval while maintaining acceptable continuous task performance. Thus, a figure of merit for overall quality of performance should be primarily a measure of time to perform discrete subtasks combined with a measure of basic vehicle control. Thus, the proposed figure of merit requires doing a task analysis on a series of performance, or runs, of a particular task, listing each discrete task and its associated time, and calculating the mean and standard deviation of these times, along with the mean and standard deviation of tracking error for the whole task. A set of simulator data on 30 runs of a landing task was obtained and a figure of merit will be calculated for each run. The figure of merit will be compared for voice and data link, so that the impact of this technology on total crew performance (not just communication performance) can be assessed. The effect of data link communication on other cockpit tasks will also be considered.

Full Text Available We report observations on fur-rubbing with leaves from Piper aduncum by a San Martín titi monkey, Callicebus oenanthe. Fur-rubbing occurred during the transition from the dry to the rainy season in a titi monkey group living in a forest fragment in the Moyobamba region of Peru. Since Piper leaves include very potent compounds that may affect ectoparasites, we tentatively interpret the observed fur-rubbing as self-medication.

Data mart construction based on semantic annotation of scientific articles: A case study for the prioritization of drug targets.

Science.gov (United States)

Teixeira, Marlon Amaro Coelho; Belloze, Kele Teixeira; Cavalcanti, Maria Cláudia; Silva-Junior, Floriano P

2018-04-01

Semantic text annotation enables the association of semantic information (ontology concepts) to text expressions (terms), which are readable by software agents. In the scientific scenario, this is particularly useful because it reveals a lot of scientific discoveries that are hidden within academic articles. The Biomedical area has more than 300 ontologies, most of them composed of over 500 concepts. These ontologies can be used to annotate scientific papers and thus, facilitate data extraction. However, in the context of a scientific research, a simple keyword-based query using the interface of a digital scientific texts library can return more than a thousand hits. The analysis of such a large set of texts, annotated with such numerous and large ontologies, is not an easy task. Therefore, the main objective of this work is to provide a method that could facilitate this task. This work describes a method called Text and Ontology ETL (TOETL), to build an analytical view over such texts. First, a corpus of selected papers is semantically annotated using distinct ontologies. Then, the annotation data is extracted, organized and aggregated into the dimensional schema of a data mart. Besides the TOETL method, this work illustrates its application through the development of the TaP DM (Target Prioritization data mart). This data mart has focus on the research of gene essentiality, a key concept to be considered when searching for genes showing potential as anti-infective drug targets. This work reveals that the proposed approach is a relevant tool to support decision making in the prioritization of new drug targets, being more efficient than the keyword-based traditional tools.

MART-10, a New Generation of Vitamin D Analog, Is More Potent than 1α,25-Dihydroxyvitamin D3 in Inhibiting Cell Proliferation and Inducing Apoptosis in ER+ MCF-7 Breast Cancer Cells

Full Text Available Hormone antagonist therapy for estrogen receptor positive (ER+ breast cancer patients post radical surgery and radiation therapy has a poor prognosis and also causes bone loss. 1α,25-dihydroxyvitamin D3 [1α,25(OH2D3] is a potent antitumor agent in pre-clinical studies, but caused hypercalcemia when its effective antitumor doses were used. Therefore, we investigated the effects of a less-calcemic 1α,25(OH2D3 analog, 19-nor-2α-(3-hydroxypropyl-1α,25-dihydroxyvitamin D3 (MART-10, on ER+MCF-7 cells. We demonstrate that MART-10 is 500- to 1000-fold more potent than 1α,25(OH2D3 in inhibiting cell growth in a dose- and time-dependent manner. MART-10 is also much more potent in arresting MCF-7cell cycle progression at G0/G1 phase as compared to 1α,25(OH2D3, possibly mediated by a greater induction of p21 and p27 expression. Moreover, MART-10 is more active than 1α,25(OH2D3 in causing cell apoptosis, likely through a higher BAX/Bcl expression ratio and the subsequent cytochrome C release from mitochondria to cytosol. Based on our in vitro findings, MART-10 could be a promising vitamin D analog for the potential treatment of breast cancer, for example, ER+ patients, to decrease the tumor relapse rate and the side effect on bone caused by antihormone regimens. Thus, further in vivo animal study is warranted.

2001-01-01

A statistical study of the detection process demonstrates that the free parameter is essential to compute the counting efficiency in both CIEMAT/NIST and TDCR methods. An analysis of the computed counting efficiencies shows the uselessness of old definition of the figure of merit. A new definition is required and we adopt the idea of taking quantities related with the output of the photomultiplier. In addition, we justify the application of the chemical quenching simulation with the electronic variation of the photomultiplier gain. Finally, we describe a new procedure to determine the figure of merit and the optimum ionization-quenching factor from the pulse spectrum of different radionuclides. The robustness of the new procedure is tested with three different sets of stopping power for low-energy electrons

MART-1, Melan-A, and Tyrosinase have shown encouraging results for evaluation of melanoma micrometastases in sentinel lymph nodes, as compared to conventionally used S-100 protein and HMB-45. To achieve higher sensitivity, some studies recommend evaluation of three sections, each at intervals of 200 μ. This would mean, routine staining of three adjacent sections in each of the three clusters at intervals of 200 μ, requiring nine slides resulting in added expense. If a cocktail of these antibodies could be used, only one section would be required instead of three generating significant cost savings. We prepared a combination of monoclonal antibodies to these three immunomarkers in optimized dilutions (MART-1, clone M2-7C10, dilution 1:500; Melan-A, clone A103, dilution 1:100; and Tyrosinase, clone T311, dilution 1:50) and designated it as 'MCW melanoma cocktail'. Formalin-fixed paraffin-embedded tissue sections of sentinel lymph nodes from patients with cutaneous melanoma, without macro-metastases were evaluated with this cocktail. Melanoma micrometastases were easily detectable with the cocktail in 41 out of 188 slices (8/24 cases). The diagnostic accuracy amongst five pathologists did not show statistically significant difference. Out of 188 slices, 78 had adjacent sections immunostained individually with MART-1 and Melan-A during our previous study. Of these 78 slices, 21 were positive for melanoma micrometastases with MART-1 and Melan-A individually. However, the adjacent section of these slices immunostained with the cocktail detected metastases in four additional slices. Thus, MART-1 and Melan-A could not detect melanoma micrometastases individually in 16% (4/25) of slices positive with the cocktail. Benign capsular nevi were immunoreactive for the cocktail in 4.8% (9/188) slices. All 81 slices of negative test controls (sentinel lymph nodes of mammary carcinoma) were interpreted correctly as negative for melanoma micrometastases. The melanoma

Martí recogió una valiosa herencia pedagógica de avanzada, representada en Félix Varela, José de la Luz y Caballero, Rafael María de Mendive y otros destacados maestros a los que, incluso, dedicó algunas de sus crónicas. Su ideario está presente en nuestra gran obra educacional y se concreta en una serie de elementos entre los que se destacan la educación intelectual sólida con carácter científico; la educación moral sobre principios éticos del patriotismo, el latinoamericanismo, la honradez, la sinceridad y la modestia; la igualdad de derechos; la educación estética dirigida al desarrollo en los educandos de expresar y percibir, sentir y disfrutar la belleza; la educación vinculada al trabajo, consideró de gran importancia la educación física. Esto pone de manifiesto que concebía la educación con carácter integral, y manifestó……”la educación de los hombres es la forma futura de los pueblos”. Para Martí la educación que ofrece la escuela, tiene que estar necesariamente de acuerdo a su tiempo y al respecto expresó, “educar es depositar en cada hombre toda la obra humana que le ha antecedido, es hacer a cada hombre resumen del mundo viviente, hasta el día en que vive; es ponerlo a nivel de su tiempo, para que flote sobre él, y no dejarlo debajo de su tiempo, con lo que no podrá salir a flote, es preparar al hombre para la vida”.

Maytenus ilicifolia Mart. ex Reiss. Maytenus ilicifolia (Celastraceae) is a native plant of South America and popularly known as 'espinheira-santa'. The aim of this study was to evaluate the antioxidant capacity of extracts and isolated compounds from this plant. The antioxidant activity of the crude and semipurified extracts and isolated compounds was evaluated through DPPH-radical and phosphomolybdenum-complex assays. By both methods, the ethyl-acetate fraction demonstrated better antioxidant capacity compared with vitamin C and trolox. In the compounds, the higher the number of hydroxyls, the greater the antioxidant activity. In addition, stereochemistry influenced antioxidant activity, i.e., compounds with 2 R,3 R showed greater activity than those with 2 R,3 S. (author)

Full Text Available Pneumatophores of Mauritia vinifera Mart. were collected from six month-old plants maintained submerged in fresh water to induce pneumatophore formation. Twenty day-old pneumatophores had a quite prominent root cap. The epidermis was composed of hexagonal cells, tangentially distributed along the cylindric surface of the organ. In transverse section these pneumatophores had a simple epidermis over several layers of sclerified parenchyma, which covered an aerenchyma with large intercellular spaces. The endodermal cells had Casparian strips. The vascular cylinder was polyarch, with a pith and surrounded by a unisseriate pericycle. Anatomically the 4 month-old pneumatophores were similar to the younger ones, except for the absence of the epidermis. The epidermis is replaced by a protective tissue, whose lignified and suberized cells projected themselves outwards, giving it a filamentous aspect. There was no accumulation of starch or tannins in the pneumatophores, except for the presence of statoliths in the root cap. No lenticels were observed in pneumatophores of M. vinifera. The main function of the pneumatophores of M. vinifera is to allow gas exchange, facilitating the supply of oxygen to the submerged root portions.Pneumatóforos de Mauritia vinifera Mart. foram coletados de plantas com seis meses de idade mantidas submersas em água com o objetivo de induzir a formação de pneumatóforos.

On the Fazenda Água Limpa (15º 45'S, 47º 57'W of the Universidade de Brasilia, 38 individuals of this species were measured in the field, the parts above ground were harvested, separated into components and oven dried. The best regression equations to estimate biomass were geometric and the best fit was between total height and total biomass (r² = 0.923. The economically useful portions, the leaves and branches accounted for approximately 20% of total above ground dry weight, but when used as the dependent variable, the strength of the relationship decreased (r² = 0.694. The relationship between branch diameter and leaf biomass was similar to that between height and leaf dry weight (r² = 0.600. The relation between the number of leaves and their biomass was linear but weak. The development of these equations is the first step towards the implementation of plans for sustainable use of this species.Para o uso sustentável das espécies vegetais nativas o conhecimento da quantidade de biomassa disponível é necessário.

The assessment of science: the relative merits of post-publication review, the impact factor, and the number of citations.

Science.gov (United States)

Eyre-Walker, Adam; Stoletzki, Nina

2013-10-01

The assessment of scientific publications is an integral part of the scientific process. Here we investigate three methods of assessing the merit of a scientific paper: subjective post-publication peer review, the number of citations gained by a paper, and the impact factor of the journal in which the article was published. We investigate these methods using two datasets in which subjective post-publication assessments of scientific publications have been made by experts. We find that there are moderate, but statistically significant, correlations between assessor scores, when two assessors have rated the same paper, and between assessor score and the number of citations a paper accrues. However, we show that assessor score depends strongly on the journal in which the paper is published, and that assessors tend to over-rate papers published in journals with high impact factors. If we control for this bias, we find that the correlation between assessor scores and between assessor score and the number of citations is weak, suggesting that scientists have little ability to judge either the intrinsic merit of a paper or its likely impact. We also show that the number of citations a paper receives is an extremely error-prone measure of scientific merit. Finally, we argue that the impact factor is likely to be a poor measure of merit, since it depends on subjective assessment. We conclude that the three measures of scientific merit considered here are poor; in particular subjective assessments are an error-prone, biased, and expensive method by which to assess merit. We argue that the impact factor may be the most satisfactory of the methods we have considered, since it is a form of pre-publication review. However, we emphasise that it is likely to be a very error-prone measure of merit that is qualitative, not quantitative.

TCRs Used in Cancer Gene Therapy Cross-React with MART-1/Melan-A Tumor Antigens via Distinct Mechanisms

Energy Technology Data Exchange (ETDEWEB)

Borbulevych, Oleg Y.; Santhanagopolan, Sujatha M.; Hossain, Moushumi; Baker, Brian M. (Notre)

2013-09-18

T cells engineered to express TCRs specific for tumor Ags can drive cancer regression. The first TCRs used in cancer gene therapy, DMF4 and DMF5, recognize two structurally distinct peptide epitopes of the melanoma-associated MART-1/Melan-A protein, both presented by the class I MHC protein HLA-A*0201. To help understand the mechanisms of TCR cross-reactivity and provide a foundation for the further development of immunotherapy, we determined the crystallographic structures of DMF4 and DMF5 in complex with both of the MART-1/Melan-A epitopes. The two TCRs use different mechanisms to accommodate the two ligands. Although DMF4 binds the two with a different orientation, altering its position over the peptide/MHC, DMF5 binds them both identically. The simpler mode of cross-reactivity by DMF5 is associated with higher affinity toward both ligands, consistent with the superior functional avidity of DMF5. More generally, the observation of two diverging mechanisms of cross-reactivity with the same Ags and the finding that TCR-binding orientation can be determined by peptide alone extend our understanding of the mechanisms underlying TCR cross-reactivity.

Decoction of roots of the Amazonian palm acai (Euterpe precatoria Mart.) is widely used by Brazilian and Peruvian people as an anti-inflammatory, to heal kidney and liver diseases and against snake bites. In this study, the antioxidant activity of extracts and flavonoids (quercetin, catechin, epicatechin, rutin and astilbin) isolated from roots and leaf stalks of E. precatoria was investigated using {beta}-carotene in TLC plates and DPPH radical scavenging in a spectrophotometric bioassay. All extracts and flavonoids showed activity. Also, the cytotoxic activity of these extracts was evaluated by the brine shrimp (Artemia salina) larvicide bioassay and was lower than that of lapachol, used as control. The presence of flavonoids and sitosterol-3-O-{beta}-D-glucopyranoside in the extracts can justify the use of the plant in traditional medicine. (author)

Cabralea canjerana (Vell.) Mart. is a tree that occurs frequently in secondary forests of Maringá, Paraná, Brazil and presents a valuable wood. Its flowering time occurs from August to October and the anthesis occurs during the night. Its flowers are visited by Lepidoptera-Noctuidae. The flowers are unisexual and solitary or arranged in panicles. The perianth presents a papillose epidermis with striate cuticle and a parenchymatic mesophyll. Ten stamens constitute the androecium and are arranged in a staminal tube with anthers. The anthers present epidermis, endothecium, two median layers and secretory tapetum with binucleate cells. The semi-inferior ovary presents anatropous, bitegmic and crassinucleate ovules. The nectaries are located in the base of the ovary and staminal tube and they present papillose epidermis with stomata and secretory parenchyma with a conspicuous phloematic tissue.

In Quest of the Antique: The Bazaar, Exchange and Mart and the Democratization of Collecting, 1926-42.

The popularization of antique collecting is typically located in the second half of the twentieth century, with the rise of 'retrochic' and the emergence of new markets and online trading websites for anonymously exchanging second-hand goods. Close study of the printed literature connected with the inter-war second-hand trade, however, challenges conventional chronologies in the history of consumer culture, and can provide a new perspective on the role of collecting in British social and cultural life. This article examines the period, after the late 1920s, during which The Bazaar, Exchange and Mart reinvented itself as a forum for antique and decorative art enthusiasts. It argues that, in speaking to and publishing contributions from so-called 'small collectors', this 'Popular Weekly for Collectors and Connoisseurs' helped shape a modern and democratic culture of art appreciation in which ordinary people were actively invited to participate. The private correspondence archive of a Buckinghamshire subscriber who used the Exchange and Mart to sell his collection of 'Egyptian, Greek, and Roman Antiquities' to readers across the country during the 1930s reveals an intimate portrait of the desires, fantasies, and pleasures associated with the popular experience of collecting in pre-war Britain. © The Author [2016].

2008-01-01

Current merit functions for 2D/3D registration usually rely on comparing pixels or small regions of images using some sort of statistical measure. Problems connected to this paradigm the sometimes problematic behaviour of the method if noise or artefacts (for instance a guide wire) are present on the projective image. We present a merit function for 2D/3D registration which utilizes the decomposition of the X-ray and the DRR under comparison into orthogonal Zernike moments; the quality of the match is assessed by an iterative comparison of expansion coefficients. Results in a imaging study on a physical phantom show that--compared to standard cross--correlation the Zernike moment based merit function shows better robustness if histogram content in images under comparison is different, and that time expenses are comparable if the merit function is constructed out of a few significant moments only.

The switching of the magnetic configuration of giant magnetoresistance multilayers not only changes the electrical and thermal conductivities but also the thermopower. We study the magnetotransport and the magnetothermoelectric properties of Co/Cu multilayer devices in a lateral thermal gradient. The Seebeck coefficient reaches values up to −18 μV/K at room temperature and shows a magnetic field dependence up to 28.6% upon spin reversal. In combination with thermal conductivity data of the same Co/Cu stack, we find a magnetothermoelectric figure of merit of up to 65%. Furthermore, a magneto-power factor of up to 110% is derived.

The clinical case report: a review of its merits and limitations.

Science.gov (United States)

Nissen, Trygve; Wynn, Rolf

2014-04-23

The clinical case report has a long-standing tradition in the medical literature. While its scientific significance has become smaller as more advanced research methods have gained ground, case reports are still presented in many medical journals. Some scholars point to its limited value for medical progress, while others assert that the genre is undervalued. We aimed to present the various points of view regarding the merits and limitations of the case report genre. We searched Google Scholar, PubMed and select textbooks on epidemiology and medical research for articles and book-chapters discussing the merits and limitations of clinical case reports and case series. The major merits of case reporting were these: Detecting novelties, generating hypotheses, pharmacovigilance, high applicability when other research designs are not possible to carry out, allowing emphasis on the narrative aspect (in-depth understanding), and educational value. The major limitations were: Lack of ability to generalize, no possibility to establish cause-effect relationship, danger of over-interpretation, publication bias, retrospective design, and distraction of reader when focusing on the unusual. Despite having lost its central role in medical literature in the 20th century, the genre still appears popular. It is a valuable part of the various research methods, especially since it complements other approaches. Furthermore, it also contributes in areas of medicine that are not specifically research-related, e.g. as an educational tool. Revision of the case report genre has been attempted in order to integrate the biomedical model with the narrative approach, but without significant success. The future prospects of the case report could possibly be in new applications of the genre, i.e. exclusive case report databases available online, and open access for clinicians and researchers.

Maytenus ilicifolia Mart. ex Reiss. Maytenus ilicifolia (Celastraceae) is a native plant of South America and popularly known as 'espinheira-santa'. The aim of this study was to evaluate the antioxidant capacity of extracts and isolated compounds from this plant. The antioxidant activity of the crude and semipurified extracts and isolated compounds was evaluated through DPPH-radical and phosphomolybdenum-complex assays. By both methods, the ethyl-acetate fraction demonstrated better antioxidant capacity compared with vitamin C and trolox. In the compounds, the higher the number of hydroxyls, the greater the antioxidant activity. In addition, stereochemistry influenced antioxidant activity, i.e., compounds with 2 R,3 R showed greater activity than those with 2 R,3 S. (author)

Merits and difficulties in adopting codes, standards and nuclear regulations

International Nuclear Information System (INIS)

El-Saiedi, A.F.; Morsy, S.; Mariy, A.

1978-01-01

Developing countries planning for introducing nuclear power plants as a source of energy have to develop or adopt sound regulatory practices. These are necessary to help governmental authorities to assess the safety of nuclear power plants and to perform inspections needed to confirm the established safe and sound limits. The first requirement is to form an independent regulatory body capable of setting up and enforcing proper safety regulations. The formation of this body is governed by several considerations related to local conditions in the developing countries, which may not always be favourable. It is quite impractical for countries with limited experience in the nuclear power field to develop their own codes, standards and regulations required for the nuclear regulatory body to perform its tasks. A practical way is to adopt codes, standards and regulations of a well-developed country. This has merits as well as drawbacks. The latter are related to problems of personnel, software, equipment and facilities. The difficulties involved in forming a nuclear regulatory body, and the merits and difficulties in adopting foreign codes, standards and regulations required for such body to perform its tasks, are discussed in this paper. Discussions are applicable to many developing countries and particular emphasis is given to the conditions and practices in Egypt. (author)

From the original polar motion (PM) measurements performed during the MERIT Campaign, the Chandler and the annual components are removed. The analysis of the residuals shows a high level of significant correlation between the various techniques mainly for phenomenon ranging from 30 days to a few months. For periods smaller than one month the series are not correlated except for the X component, deduced from laser and Doppler techniques, which remains significant at the 99 percent level. These results led to the belief for a new earth rotation service open to different sources of data.

Figures of merit for detectors in digital radiography. II. Finite number of secondaries and structured backgrounds

International Nuclear Information System (INIS)

Pineda, Angel R.; Barrett, Harrison H.

2004-01-01

The current paradigm for evaluating detectors in digital radiography relies on Fourier methods. Fourier methods rely on a shift-invariant and statistically stationary description of the imaging system. The theoretical justification for the use of Fourier methods is based on a uniform background fluence and an infinite detector. In practice, the background fluence is not uniform and detector size is finite. We study the effect of stochastic blurring and structured backgrounds on the correlation between Fourier-based figures of merit and Hotelling detectability. A stochastic model of the blurring leads to behavior similar to what is observed by adding electronic noise to the deterministic blurring model. Background structure does away with the shift invariance. Anatomical variation makes the covariance matrix of the data less amenable to Fourier methods by introducing long-range correlations. It is desirable to have figures of merit that can account for all the sources of variation, some of which are not stationary. For such cases, we show that the commonly used figures of merit based on the discrete Fourier transform can provide an inaccurate estimate of Hotelling detectability

Significant enhancement of the thermoelectric figure of merit of polycrystalline Si films by reducing grain size

International Nuclear Information System (INIS)

Valalaki, K; Nassiopoulou, A G; Vouroutzis, N

2016-01-01

The thermoelectric properties of p-type polycrystalline silicon thin films deposited by low pressure chemical vapour deposition (LPCVD) were accurately determined at room temperature and the thermoelectric figure of merit was deduced as a function of film thickness, ranging from 100 to 500 nm. The effect of film thickness on their thermoelectric performance is discussed. More than threefold increase in the thermoelectric figure of merit of the 100 nm thick polysilicon film was observed compared to the 500 nm thick film, reaching a value as high as 0.033. This enhancement is mainly the result of the smaller grain size in the thinner films. With the decrease in grain size the resistivity of the films is increased twofold and electrical conductivity decreased, however the Seebeck coefficient is increased by 30% and the thermal conductivity is decreased eightfold, being mainly at the origin of the increased figure of merit of the 100 nm film. Our experimental results were compared to known theoretical models and the possible mechanisms involved are presented and discussed. (paper)

This study evaluated, in vitro, the antimicrobial activity of the hexane extract (JCHE), methanol extract (JCME), and chloroform fraction (JCCF) of bark from Jacaranda cuspidifolia Mart. (Family Bignoniaceae), a Brazilian medicinal plant, traditionally used as anti-syphilis and anti-gonorrhea treatment. The antimicrobial activity was evaluated using the disc diffusion method followed by the determination of minimum inhibitory concentration (MIC) values. JCHE was not active against the bacteria evaluated. JCME presented antibacterial activity against Streptococcus pyogenes, Staphylococcus aureus, and Neisseria gonorrhoeae with MIC values of 16.3 mg/mL, 9.1 mg/mL, and 25.2 mg/mL, respectively. JCCF was active against Staphylococcus epidermidis, S. aureus, Proteus mirabilis, Serratia marcescens, S. pyogenes, Enterobacter aerogenes, and N. gonorrhoeae with MIC values of 18.3 mg/mL, 9.3 mg/mL, 6.3 mg/mL, 6.1 mg/mL, 9.2 mg/mL, 6.2 mg/mL, and 25.2 mg/mL, respectively. Phytochemical analysis of JCME and JCCF gave positive results for saponins, coumarins, flavonoids, tannins, quinones, alkaloids, triterpenes, and steroids. Verbascoside was isolated and identified as a major peak in JCME and JCCF high-performance liquid chromatography fingerprints and might contribute to the observed antimicrobial activity.

Scalings of key parameters with L, B/sub 0 /, and I are presented at several operating points, including (a) optimal path to ignition (saddle point), (b) ignition at minimum beta, (c) ignition at 10 keV, and (d) maximum performance at the limits of density and beta. Expressions for the saddle point and the minimum conditions needed for ohmic ignition are derived analytically for any confinement model of the form tau/sub E/ ∼ n/sup x/T/sup y/. For a wide range of confinement models, the ''figure of merit'' parameters and I are found to give a good indication of the relative performance of the devices where q* is the cylindrical safety factor. As an illustration, the results are applied to representative ''CIT'' (as a class of compact, high-field ignition tokamaks) and ''Super-JETs'' [a class of large-size (few x JET), low-field, high-current (≥20-MA) devices.

In 1930 he published in Valencia, in Castilian, his only work of fiction, an unobtainable Voyage To Mars which is a true socialist utopia. That whole world is established as a single global state, of which he details all that goes from a Constitution to Municipal Ordinances, through the administration of justice, education, health and Women’s Rights, with only one race and one language, and as peculiar a institution as the Agricultural Army or the Humanitarian Sisters.Modesto Brocos (1852-1936 fue un notable pintor compostelano que emigró joven a Brasil y allí vivió respetado hasta su muerte.

Rural maternity care: can we learn from Wal-Mart?

Science.gov (United States)

van Teijlingen, E R; Pitchforth, E

2010-03-01

In many countries rural maternity care is under threat. Consequently rural pregnant women will have to travel further to attend larger maternity units to receive care and deliver their babies. This trend is not dissimilar from the disappearance of other rural services, such as village shops, banks, post offices and bus services. We use a comparative approach to draw an analogy with large-scale supermarkets, such as the Wal-Mart and Tesco and their effect on the viability of smaller rural shops, depersonalisation of service and the wider community. The closure of a community-maternity unit leads to women attending a different type of hospital with a different approach to maternity care. Thus small community-midwifery units are being replaced, not by a very similar unit that happens to be further away, but by a larger obstetric unit that operates on different models, philosophy and notions of risk. Comparative analysis allows a fresh perspective on the provision of rural maternity services. We argue that previous discussions focusing on medicalisation and change in maternity services can be enhanced by drawing on experience in other sectors and taking a wider societal lens.

Mites associated to Xylopia aromatica (Lam. Mart. (Annonaceae in urban and rural fragments of semidecidual forest

Full Text Available Mites associated to Xylopia aromatica (Lam. Mart. (Annonaceae in urban and rural fragments of semidecidual forest. Native plants can shelter a great diversity of mites. Notwithstanding, the conservation of the forest fragments where the plants are located can influence the structure of the mites community. Generally, in homogenous environments the diversity is lower due to the dominance of one or a few species. In this work, we studied the mite community on Xylopia aromatica (Lam. Mart. (Annonaceae in two fragments of semidecidual forest: one on rural and other on urban area. Seven individuals of X. aromatica were monthly sampled from April 2007 to March 2008, in each of these fragments. Descriptive indexes of diversity, dominance and evenness were applied to verify the ecological patterns of the mite community, besides the Student's t-test to compare the abundance between the fragments. We collected 27,365 mites of 37 species belonging to 11 families. Calacarus sp. (Eriophyidae was the most abundant species, representing 73% of the total sampled. The abundance was greater in the urban fragment (67.7%, with the diversity index reaching only 25% of the theoretical maximum expected. Probably, these values might have been influenced by the location of this fragment in the urban area, being more homogeneous and submitted directly to the presence of atmospheric pollution. In this manner, X. aromatica is able to shelter a higher diversity of mites when inserted in preserved ecosystems, since the highest diversity of available resources allows the establishment of richer and most diverse mite community.

Figures of merit for measuring aging management program effectiveness

1991-01-01

One of the requirements for nuclear plant license renewal may be the establishment and demonstration of an effective aging management program. An analysis of both qualitative and quantitative information will be required to define the contents of this aging management program. The authors propose two quantitative figures of merit, Mean Event Detection Frequency and Mean Renewal Rate, that can be used to compare the effectiveness of various inspection, surveillance, test, and monitoring (ISTM) activities for aging mitigation. An example showing the relative effectiveness of an enhanced Loose Parts Monitoring System with current ISTM activities for steam generators and reactor internals is provided. (author)

Physiological responses of Alternanthera philoxeroides (Mart.) Griseb leaves to cadmium stress

2007-01-01

Aquatic macrophytes were found to be the potential scavengers of heavy metals from aquatic environment. In this study, several physiological responses of Alternanthera philoxeroides (Mart.) Griseb leaves to elevated concentrations of cadmium (up to 10 mM) were investigated. It was found that A. philoxeroides was able to accumulate cadmium in its leaves. The pigment contents decreased with the increase of the Cd concentrations. The Cd could induce rise of the activity of peroxidase (POD) at lower concentration (<5 mM), however, when the concentration of Cd rose up to 10 mM, the POD activity declined. The changes of superoxide dismutase (SOD) and Catalase (CAT) activities were exactly opposite to that of POD. In the leaves of Cd-treated fronds, the amounts of three polypeptides with apparent molecular weights 80, 39 and 28 kDa, respectively, were became visible in SDS-PAGE. The nature of these polypeptides remains to be determined. - Cd modified a number of physiological processes and particularly chlorophyll degradation

Improved merit order and augmented Lagrange Hopfield network for short term hydrothermal scheduling

International Nuclear Information System (INIS)

Vo Ngoc Dieu; Ongsakul, Weerakorn

2009-01-01

This paper proposes an improved merit order (IMO) combined with an augmented Lagrangian Hopfield network (ALHN) for solving short term hydrothermal scheduling (HTS) with pumped-storage hydro plants. The proposed IMO-ALHN consists of a merit order based on the average production cost of generating units enhanced by heuristic search algorithm for finding unit scheduling and a continuous Hopfield neural network with its energy function based on augmented Lagrangian relaxation for solving constrained economic dispatch (CED). The proposed method is applied to solve the HTS problem in five stages including thermal, hydro and pumped-storage unit commitment by IMO and heuristic search, constraint violations repairing by heuristic search and CED by ALHN. The proposed method is tested on the 24-bus IEEE RTS with 32 units including 4 fuel-constrained, 4-hydro, and 2 pumped-storage units scheduled over a 24-h period. Test results indicate that the proposed IMO-ALHN is efficient for hydrothermal systems with various constraints.

Full Text Available Combretum leprosum Mart. is a tree species native of the Caatinga, used in the restoration of degraded areas and in folk medicine. Thus, this research aimed to evaluate the germination and vigor of the seeds subjecting them to different pre-germinative treatments, temperatures and substrates. In the first experi- ment, we tested the pre-germinative treatments: mechanical scarification with sandpaper, chemical scarification with H2SO4 for 1, 5, 10 and 20 minutes, immersion in water at 80 oC and imbibition in distilled water for 24 hours, beyond of the control. In the second experiment, after treatment of imbibition in water for 24 hours, the experimental design was completely randomized in a factorial 5 x 4 (five substrates: into paper, sand, coconut fiber, vermiculite and paper towel organized in the form of rolls; and four temperatures: 25, 30, 35 and 20-30 oC. The following parameters were evalueted: seed moisture content, germination, germination speed index, first germination count and seedling length and dry matter weight. The seeds of Combretum leprosum have not coat dormancy. However, pre-germinative treatments of mechanical scarification with sandpaper and imbibi- tion in water for 24 hours allows better expression of seeds vigor. The paper towel and the temperatures of 25, 30 and 20-30 oC provide adequate conditions for evaluating the germination of Combretum leprosum seeds.

Full Text Available Abstract The diet of the stone marten (Martes foina was studied analysing 63 faeces collected from February 1990 to December 1991. The results were expressed as relative percentage of frequency (Fr% and as percentage of mean bulk (Vm%. Mammals, mainly rodents, were the staple in the diet (annual Vm% = 62.9 and reached a maximum peak in winter (Vm% = 79.4. Vegetables were mostly represented by Rosaceae fruits (annual Vm% = 22.3 and were consumed during all year round. Insects, mainly Coleoptera and Orthoptera, were fairly frequently eaten, although their volume was not remarkable (annual Vm% = 4.1. Birds and garbage were scarcely used. The trophic niche breadth of the stone marten, evaluated using the Levin's index (B, varied from 2.49 in winter to 4.8 in summer.

Full Text Available Eichhornia crassipes (Mart. Solms is an aquatic invasive weed throughout the tropical and subtropical regions of the world. The plant rarely produces any fruit under natural condition In order to understand the causes of failure of seed set in this plant various aspect of pollen biology were studied. Pollen fertility and pollen viability was assessed using Muntzing� s mixture and in acetic orcein and TTZ, while pollen germination was assessed with different concentrations of sucrose supplemented with boric acid and Ca and Mg salts. The aim of present study was to find out the cause of sexual incompatibility of Eichhornia crassipes (Mart. Solms. In spite of high pollen fertility, pollen viability and pollen germination the species show hardly any fruit set under natural condition. The abnormal pollen germination like curling of pollen tubes, shrinkage of pollen tube tips and bending of pollen tube might be reasons of sexual incompatibility of this species. It is observed that the taxa required comparatively low sucrose concentration (5% for their optimal in vitro pollen germination (54.08%. Boric acid to certain extent also influences the in vitro pollen germination (56.2%. In the present investigation the nature of substrate in association with the effect of Boric acid, CaCO3, MgSO4 on the in vitro pollen germination of Eichhornia crassipes is also worked out. However the tested salts show no significant effect on pollen germination in the present study.

Analysis of the profiles of methanol extracts by High Performance Liquid Chromatography - Reversed Phase recorded the presence of phenolic compounds derivatives of verbascoside, suggesting their probable responsibility for the antimycobacterial action.

Merit-order effects of renewable energy and price divergence in California’s day-ahead and real-time electricity markets

We answer two policy questions: (1) what are the estimated merit-order effects of renewable energy in the California Independent System Operator’s (CAISO’s) day-ahead market (DAM) and real-time market (RTM)? and (2) what causes the hourly DAM and RTM prices to systematically diverge? The first question is timely and relevant because if the merit-order effect estimates are small, California’s renewable energy development is of limited help in cutting electricity consumers’ bills but also has a lesser adverse impact on the state’s investment incentive for natural-gas-fired generation. The second question is related to the efficient market hypothesis under which the hourly RTM and DAM prices tend to converge. Using a sample of about 21,000 hourly observations of CAISO market prices and their fundamental drivers during 12/12/2012–04/30/2015, we document statistically significant estimates (p-value≤0.01) for the DAM and RTM merit-order effects. This finding lends support to California’s adopted procurement process to provide sufficient investment incentives for natural-gas-fired generation. We document that the RTM-DAM price divergence partly depends on the CASIO’s day-ahead forecast errors for system loads and renewable energy. This finding suggests that improving the performance of the CAISO’s day-ahead forecasts can enhance trading efficiency in California’s DAM and RTM electricity markets. - Highlights: •Estimate the day-ahead and real-time merit-order effects of renewable energy in California. •Document statistically significant merit-order effects of solar and wind energy. •Document the difference between the day-ahead and real-time prices. •Attribute the price differences to forecast errors for load, solar and wind energy. •Discuss the evidence’s implications for California’s energy policy.

Arsenene and Antimonene: Two-Dimensional Materials with High Thermoelectric Figures of Merit

KAUST Repository

Sharma, S.

2017-10-25

We study the thermoelectric properties of As and Sb monolayers (arsenene and antimonene) using density-functional theory and the semiclassical Boltzmann transport approach. The materials show large band gaps combined with low lattice thermal conductivities. Specifically, the small phonon frequencies and group velocities of antimonene lead to an excellent thermoelectric response at room temperature. We show that n-type doping enhances the figure of merit.

Ultrahigh figure-of-merit for hydrogen generation from sodium borohydride using ternary metal catalysts

Science.gov (United States)

Hu, Lunghao; Ceccato, R.; Raj, R.

We report further increase in the figure-of-merit (FOM) for hydrogen generation from NaBH 4 than reported in an earlier paper [1], where a sub-nanometer layer of metal catalysts are deposited on carbon nanotube paper (CNT paper) that has been functionalized with polymer-derived silicon carbonitride (SiCN) ceramic film. Ternary, Ru-Pd-Pt, instead of the binary Pd-Pt catalyst used earlier, together with a thinner CNT paper is shown to increase the figure-of-merit by up to a factor of six, putting is above any other known catalyst for hydrogen generation from NaBH 4. The catalysts are prepared by first impregnating the functionalized CNT-paper with solutions of the metal salts, followed by reduction in a sodium borohydride solution. The reaction mechanism and the catalyst efficiency are described in terms of an electric charge transfer, whereby the negative charge on the BH 4 - ion is exchanged with hydrogen via the electronically conducting SiCN/CNT substrate [1].

2018-04-01

In order to improve the thermoelectric performance of TiCoSb we have substituted 50% of Ti equally with Zr and Hf at Ti site and Sb with Sn and Se equally at Sb site. The electronic structure of Ti0.5Zr0.25Hf0.25CoSn0.5Se0.5 is investigated using the full potential linearized augmented plane wave method and the thermoelectric transport properties are calculated on the basis of semi-classical Boltzmann transport theory. Our band structure calculations show that Ti0.5Zr0.25Hf0.25CoSn0.5Se0.5 has semiconducting behavior with indirect band gap value of 0.98 eV which follow the empirical rule of 18 valence-electron content to bring semiconductivity in half Heusler compounds, indicating that one can have semiconducting behavior in multinary phase of half Heusler compounds if they full fill the 18 VEC rule and this open-up the possibility of designing thermoelectrics with high figure of merit in half Heusler compounds. We show that at high temperature of around 700K Ti0.5Zr0.25Hf0.25CoSn0.5Se0.5 has high thermoelectric figure of merit of ZT = 1.05 which is higher than that of TiCoSb (˜ 0.95) suggesting that by going from ternary to multinary phase system one can enhance the thermoelectric figure of merit at higher temperatures.

Full Text Available Thermoelectric effects arising in a sample placed in a measuring oscillating loop have been studied. It has been shown that asymmetric character of flowing current results in a volumetric bundle of induced Foucault currents and regions of Peltier heat release by thermoelectric sample which leads to increasing of irreversible heat losses recorded by measuring oscillating loop. The presence of this effect has caused the emergence of ingenious non-invasive method for recording of thermoelectric materials figure of merit.

MERIT is a proof-of-principle experiment of a target station suitable as source for future muon colliders or neutrino factories. When installed at the CERN (European Organization for Nuclear Research) PS (Proton Synchrotron)complex fast-extracted high-intensity proton beams intercepted a free mercury jet inside a normal-conducting, pulsed 15-T capture solenoid magnet cooled with liquid nitrogen. Up to 25 MJ of Joule heat was dissipated in the magnet during a pulse. The fully automated, remotely controlled cryogenic system of novel design permitted the transfer of nitrogen by the sole means of differential pressures inside the vessels. This fast cycling system permitted several hundred tests in less than three weeks during the 2007 data taking campaign.

Anomalous enhancement of the thermoelectric figure of merit by V co-doping of Nb-SrTiO3

2012-05-10

The effect of V co-doping of Nb-SrTiO3 is studied by full-potential density functional theory. We obtain a stronger increase of the carrier density for V than for Nbdopants. While in Nb-SrTiO3 a high carrier density counteracts a high thermoelectric figure of merit, the trend is inverted by V co-doping. The mechanism leading to this behavior is explained in terms of a local spin-polarization introduced by the V ions. Our results indicate that magnetic co-doping can be a prominent tool for improving the thermoelectric figure of merit.

The boron neutron capture therapy (BNCT) figures of merit of advantage depth, therapeutic depth, modified advantage depth and maximum therapeutic depth have been studied as functions of [sup 10]B tumour to blood ratios and absolute levels. These relationships were examined using the Monte Carlo neutron photon transport code, MCNP, with an ideal 18.4 cm diameter neutron beam incident laterally upon an ellipsoidal neutron photon brain-equivalent model. Mono-energetic beams of 0.025 eV (thermal) and 35 eV (epithermal) were simulated. Increasing the tumour to blood [sup 10]B ratio predictably increases all figures of merit. [sup 10]B concentration was also shown to have a strong bearing on the figures of merit when low levels were present in the system. This is the result of a non-[sup 10]B dependent background dose. At higher levels however, the concentration of [sup 10]B has a diminishing influence. For boron sulphydryl (BSH), little advantage is gained by extending the blood [sup 10]B level beyond 30 ppm, whilst for D, L,-p-boronophenylalanine (BPA) this limit is 10 ppm. Applying the epithermal beam under identical conditions, the therapeutic depth reaches the brain mid-line with a tumour to blood [sup 10]B ratio of only 5.7 for BPA. For BSH, the maximum therapeutic depth reaches the brain mid-line with a tumour to blood ratio of only 1.9 with 30 ppm in the blood. Human data for these compounds are very close to these requirements. (author).

In order to decrease the minimum detectable activities (MDAs) of beta-gamma radioxenon detectors, it is important to increase the ability to resolve the individual isotopes. One proposed method for doing this is to increase the energy resolution of the beta cell through the use of silicon detectors. While silicon detectors can improve the energy resolution, it is accompanied with a decrease in detection efficiency compared to plastic scintillator beta cells. Due to the uncertainty on the impact of the competing variables, we have developed a figure-of-merit (FOM) capable of determining the impact of detector parameters on the MDAs. By utilizing the FOM to analyze different detectors, we are able to directly compare current and future detectors and estimate their impact on the radioxenon MDAs.

Investigation of High-Efficiency Wireless Power Transfer Criteria of Resonantly-Coupled Loops and Dipoles through Analysis of the Figure of Merit

Directory of Open Access Journals (Sweden)

Charles Moorey

2015-10-01

Full Text Available The efficiency of a Wireless Power Transfer (WPT system is greatly dependent on both the geometry and operating frequency of the transmitting and receiving structures. By using Coupled Mode Theory (CMT, the figure of merit is calculated for resonantly-coupled loop and dipole systems. An in-depth analysis of the figure of merit is performed with respect to the key geometric parameters of the loops and dipoles, along with the resonant frequency, in order to identify the key relationships leading to high-efficiency WPT. For systems consisting of two identical single-turn loops, it is shown that the choice of both the loop radius and resonant frequency are essential in achieving high-efficiency WPT. For the dipole geometries studied, it is shown that the choice of length is largely irrelevant and that as a result of their capacitive nature, low-MHz frequency dipoles are able to produce significantly higher figures of merit than those of the loops considered. The results of the figure of merit analysis are used to propose and subsequently compare two mid-range loop and dipole WPT systems of equal size and operating frequency, where it is shown that the dipole system is able to achieve higher efficiencies than the loop system of the distance range examined.

Full Text Available Hace más de una década el Ministerio de Educación Superior puso como meta para la Universidad Cubana, la formación de profesionales más integrales, humanistas y capaces de cumplir conscientemente su función social. A primera vista el desafío parecía solucionable desde nuestras aulas en algunos años, el tesón y la calidad de nuestros profesores se convertía entonces en el arma protagónica de aquella lucha. La verdad fue que cada aula se convirtió en un campo de batalla. Las Universidades de Ciencias Médicas tuvieron el reto particular de que la formación de sus educandos debía responder no solo a las necesidades de nuestra sociedad, sino también a las sociedades latinoamericanas, africanas y luego, a los de cualquier parte del mundo donde fueran necesarios sus empeños. Ese médico que hoy viste celosamente su bata, es el resultado de miles de horas hombre entre docentes y personal asistencial de la salud para formar a un profesional capaz y responsable, pero sobre todo embajador de lo mejor de nuestras costumbres y nuestra identidad. No es solo un profesional bien preparado en su especialidad. Es digno representante de lo que Martí llamó “hombres de luz”, capaces de poner esperanza y seguridad allí donde otros sólo habían dejado lágrimas. Durante los últimos cinco años, nuestra salud pública enfrenta la peor fuga de cerebros de las últimas cuatro décadas; lo que pudiera representar una crisis en cualquier sociedad occidental que pondría en jaque la estabilidad sistémica, en nuestro país se enfrenta con inteligencia. No dejan de ser cubanos aquellos que por mejores condiciones de vida abandonan a los suyos, o los que por perseguir el sueño estrellado terminan puliendo pisos o de jardineros en las grandes capitales del mundo. La solución está en nuestras aulas, en poner en manos de los estudiantes las herramientas que le permitan ponerse del lado de los que menos tienen y aprendan a amar su profesión por

AN ANALYTICAL FRAMEWORK FOR ASSESSING RELIABLE NUCLEAR FUEL SERVICE APPROACHES: ECONOMIC AND NON-PROLIFERATION MERITS OF NUCLEAR FUEL LEASING

2010-01-01

The goal of international nuclear policy since the dawn of nuclear power has been the peaceful expansion of nuclear energy while controlling the spread of enrichment and reprocessing technology. Numerous initiatives undertaken in the intervening decades to develop international agreements on providing nuclear fuel supply assurances, or reliable nuclear fuel services (RNFS) attempted to control the spread of sensitive nuclear materials and technology. In order to inform the international debate and the development of government policy, PNNL has been developing an analytical framework to holistically evaluate the economics and non-proliferation merits of alternative approaches to managing the nuclear fuel cycle (i.e., cradle-to-grave). This paper provides an overview of the analytical framework and discusses preliminary results of an economic assessment of one RNFS approach: full-service nuclear fuel leasing. The specific focus of this paper is the metrics under development to systematically evaluate the non-proliferation merits of fuel-cycle management alternatives. Also discussed is the utility of an integrated assessment of the economics and non-proliferation merits of nuclear fuel leasing.

Relative merits of travelling-wave and resonant operation of linac

Shoffstall, D.R.; Gallagher, W.J.

1985-01-01

Discussion of the relative merits of so-called standing wave vis-a-vis travelling wave operation of linear accelerator waveguides is complicated by various considerations. In the first instance, standing wave should be distinguished from resonant operation. Standing wave operation is exactly the same as travelling wave, excepting that the waveguide is terminated by a total reflection of power instead of a matched load. In resonant operation a length of slow wave structure is terminated, theoretically at reflection planes of symmetry; the discrete modes of resonance consist of two oppositely directed travelling wave ensembles, one of which will provide a space harmonic of an intended phase velocity

Full Text Available In this work, we analyze different configurations of a thermoelectric system (TES composed of three thermoelectric generators (TEGs. We present the following considerations: (a TES thermally and electrically connected in series (SC; (b TES thermally and electrically connected in parallel (PSC; and (c parallel thermally and series electrical connection (SSC. We assume that the parameters of the TEGs are temperature-independent. The systems are characterized by three parameters, as it has been showed in recent investigations, namely, its internal electrical resistance, R, thermal conductance under open electrical circuit condition, K, and Seebeck coefficient α. We derive the equivalent parameters for each of the configurations considered here and calculate the Figure of Merit Z for the equivalent system. We show the impact of the configuration of the system on Z, and we suggest optimum configuration. In order to justify the effectiveness of the equivalent Figure of Merit, the corresponding efficiency has been calculated for each configuration.

Full Text Available Clay deposit collected from various locations in Marte (Northern Borno, were studied to determine their physical and chemical characteristics in order to evaluate their suitability for industrial uses. Major and trace element analyses were carried out on clay samples using Inductively Couple Plasma-Optical Emission Spectrometry (ICP-OES and X- Ray Fluorescence (XRF. The result of the chemical analysis of the ten (10 samples collected showed significant amounts of SiO2 and Al2O3. Silica content ranges from 51.48 to 62.44 % while alumina varies from 12.49 to 19.00 %. The calcium oxide ranges from 1.17 to 3.39 %, Na2O ranges from 1.1 to 8.61 %, K2O from 1.54 to 3.66 %, MgO varies from 0.04 to0.14 %, Fe2O3 varies from 0.3 to 2.7 % and MnO ranges from 0.01 to 1.03 %. The result showed that the clays are mainly smectite with quartz and felspar as the main non-clay minerals. Generally, the geochemical results of the samples do not meet the standard for industrial utilization when compared to the Industrial specifications. However, for industrial utilization, some of the clay samples may be used after necessary beneficiations.

An evolutionary algorithm was applied to a mechanistic model of the mammary gland to find the parameter values that minimised the difference between predicted and actual lactation curves of milk yields in New Zealand Jersey cattle managed at different feeding levels. The effect of feeding level, genetic merit, body condition score at parturition and age on total lactation yields of milk, fat and protein, days in milk, live weight and evolutionary algorithm derived mammary gland parameters was then determined using a multiple regression model. The mechanistic model of the mammary gland was able to fit lactation curves that corresponded to actual lactation curves with a high degree of accuracy. The senescence rate of quiescent (inactive) alveoli was highest at the very low feeding level. The active alveoli population at peak lactation was highest at very low feeding levels, but lower nutritional status at this feeding level prevented high milk yields from being achieved. Genetic merit had a significant linear effect on the active alveoli population at peak and mid to late lactation, with higher values in animals, which had higher breeding values for milk yields. A type of genetic merit × feeding level scaling effect was observed for total yields of milk and fat, and total number of alveoli produced from conception until the end of lactation with the benefits of increases in genetic merit being greater at high feeding levels. A genetic merit × age scaling effect was observed for total lactation protein yields. Initial rates of differentiation of progenitor cells declined with age. Production levels of alveoli from conception to the end of lactation were lowest in 5- to 8-year-old animals; however, in these older animals, quiescent alveoli were reactivated more frequently. The active alveoli population at peak lactation and rates of active alveoli proceeding to quiescence were highest in animals of intermediate body condition scores of 4.0 to 5.0. The results

Scott, Paul; Kurth, Robert; Cox, Andrew; Olson, Rick; Rudland, Dave

2010-12-01

The MERIT project has been an internationally financed program with the main purpose of developing probabilistic models for piping failure of nuclear components and to include these models in a probabilistic code named PRO-LOCA. The principal objective of the project has been to develop probabilistic models for piping failure of nuclear components and to include these models in a probabilistic code. The MERIT program has produced a code named PRO-LOCA with the following features: - Crack initiation models for fatigue or stress corrosion cracking for previously unflawed material. - Subcritical crack growth models for fatigue and stress corrosion cracking for both initiated and pre-existing circumferential defects. - Models for flaw detection by inspections and leak detection. - Crack stability. The PRO-LOCA code can thus predict the leak or break frequency for the whole sequence of initiation, subcritical crack growth until wall penetration and leakage, instability of the through-wall crack (pipe rupture). The outcome of the PRO-LOCA code are a sequence of failure frequencies which represents the probability of surface crack developing, a through-wall crack developing and six different sizes of crack opening areas corresponding to different leak flow rates or LOCA categories. Note that the level of quality assurance of the PRO-LOCA code is such that the code in its current state of development is considered to be more of a research code than a regulatory tool.

Full Text Available The crude ethanol extract (EEOH of the bark of Maytenus rigida Mart (Celastraceae a plant used in Brazil herbal traditional medicine, was tested for anti-inflammatory, antiulcer and antidiarrhoeal activities in animal models. No acute toxicological sign was observed in animals treated with the highest dose (5000 mg/kg, p.o. or 2000 mg/kg i.p. of EEOH. The extract doses of 250, 500 or 750 mg/kg revealed a significant inhibitory effect (P < 0,01 in carrageenin-induced rat paw oedema and exhibited ulcer-protective properties against ethanol-induced ulceration in rats. An anti-diarrhoeal activity (P < 0.01 was also observed in castor-oil-induced diarrhoeal in mice. The intestinal transit was significantly (P < 0.01 reduced, however the pretreatment did not reduce the weight of intestinal contents. These results support the popular applications of Maytenus rigida for the treatment of inflammation, ulcer and diarrhoea in Brazil herbal traditional medicine.

Full Text Available The acute toxicity, the antioxidant activity, and the pharmacological activity on the gastrointestinal tract of rodents of the ethanolic extract (TFEE from the bark of Terminalia fagifolia Mart. & Zucc. (Combretaceae and of its aqueous (TFAqF, hydroalcoholic (TFHAF, and hexanic (TFHEXF partition fractions have been evaluated. TFEE presented low acute toxicity, antioxidant, and antiulcerogenic activity against ethanol-induced ulcers, which was partially blocked by pretreatment with L-NAME and indomethacin. It reduced the total acidity and raised the pH of gastric secretion. Additionally, TFEE delayed gastric emptying and slightly inhibited the small intestinal transit and also presented a weakly antidiarrheal activity. The antiulcerogenic and antioxidant activity were also detected in TFAqF and TFHAF but not in TFHEXF. The antisecretory and gastroprotective activity of TFEE partially involve the nitric oxide and prostaglandin participation. Nevertheless, TFEE, TFAqF, and TFHAF drastically reduced the mucus layer adhered to the gastric wall of rats treated with ethanol or indomethacin. Complementary studies are required in order to clarify the paradox of the presence of a gastroprotector activity in this plant that, at the same time, reduces the mucus layer adhered to the gastric wall.

Nitrogen-fixing bacteria and arbuscular mycorrhizal fungi in Piptadenia gonoacantha (Mart. Macbr.

Directory of Open Access Journals (Sweden)

Joel Quintino de Oliveira Júnior

Full Text Available Abstract The family Leguminosae comprises approximately 20,000 species that mostly form symbioses with arbuscular mycorrhizal fungi (AMF and nitrogen-fixing bacteria (NFB. This study is aimed at investigating and confirming the dependence on nodulation and biological nitrogen fixation in the specie Piptadenia gonoacantha (Mart. Macbr., which belongs to the Piptadenia group. Two consecutive experiments were performed in a greenhouse. The experiments were fully randomized with six replicates and a factorial scheme. For the treatments, the two AMF species and three NFB strains were combined to nodulate P. gonoacantha in addition to the control treatments. The results indicate this species’ capacity for nodulation without the AMF; however, the AMF + NFB combinations yielded a considerable gain in P. gonoacantha shoot weight compared with the treatments that only included inoculating with bacteria or AMF. The results also confirm that the treatment effects among the AMF + NFB combinations produced different shoot dry weight/root dry weight ratios. We conclude that AMF is not necessary for nodulation and that this dependence improves species development because plant growth increases upon co-inoculation.

BioMart Central Portal is a first of its kind, community-driven effort to provide unified access to dozens of biological databases spanning genomics, proteomics, model organisms, cancer data, ontology information and more. Anybody can contribute an independently maintained resource to the Central Portal, allowing it to be exposed to and shared with the research community, and linking it with the other resources in the portal. Users can take advantage of the common interface to quickly utilize different sources without learning a new system for each. The system also simplifies cross-database searches that might otherwise require several complicated steps. Several integrated tools streamline common tasks, such as converting between ID formats and retrieving sequences. The combination of a wide variety of databases, an easy-to-use interface, robust programmatic access and the array of tools make Central Portal a one-stop shop for biological data querying. Here, we describe the structure of Central Portal and show example queries to demonstrate its capabilities. Database URL: http://central.biomart.org. PMID:21930507

The influence nuclear power has on corporate image and the effect of offering merit information of nuclear power

2006-01-01

Many electric power companies in Japan, irrespective of their nuclear power generation ratio's difference, have nuclear power plants. These days, corporate brand image is becoming more and more important. Therefore, a survey was carried out to study the effect that nuclear power (including comparison with the other type of industry besides electric power) has on the corporate image of an electric power company. Further more, the survey includes a research about the effect on people's attitude change towards nuclear power before and after discovering the merits or benefits of nuclear power. The possibility of enhancing the corporate brand image of electric power companies by providing merit information of nuclear power was studied. (author)

The use of natural fiber reinforcement thermoplastic polymer is continuously increasing. This fact is manly due to its advantages as low cost, availability, recyclability, low energy demand and then environmental appeal if compared to synthetics fibers. The composites were prepared in different fiber volume ratios (5%, 10% and 20%) mixed with high density polyethylene (HDPE) and heated at 190 deg C. Thermogravimetric analysis and differential scanning calorimetry were used to investigate thermal stability. The composites structure was characterized by Fourier Transform Infrared spectroscopy, X-ray diffractometry. Fiber and residue of piassava (Attalea funifera Mart) chemical composition were determined by Van Soest Method. The results indicate that thermo stability of the composites of HDPE prepared with fiber volume ratios up to 20% is only slightly lowered. (author)

The composites were prepared in different fiber volume ratios (5%, 10% and 20%) mixed with high density polyethylene (HDPE) and heated at 190 deg C. Thermogravimetric analysis and differential scanning calorimetry were used to investigate thermal stability. The composites structure was characterized by Fourier Transform Infrared spectroscopy, X-ray diffractometry. Fiber and residue of piassava (Attalea funifera Mart) chemical composition were determined by Van Soest Method. The results indicate that thermo stability of the composites of HDPE prepared with fiber volume ratios up to 20% is only slightly lowered. (author)

Half-Heusler alloys have been one of the benchmark high temperature thermoelectric materials owing to their thermal stability and promising figure of merit ZT. Simonson et al. early showed that small amounts of vanadium doped in Hf0.75Zr0.25NiSn enhanced the Seebeck coefficient and correlated the change with the increased density of states near the Fermi level. We herein report a systematic study on the role of vanadium (V), niobium (Nb), and tantalum (Ta) as prospective resonant dopants in e...

A user's perspective on the merits and shortcomings of ASME Section III

International Nuclear Information System (INIS)

Antaki, G.A.

1994-01-01

There are several aspects of Section III which when compared to process industry codes (ASME VIII, ASME B31.3, API, etc.) have proven to be a significant improvement in engineering practice. There are, however, other aspects of ASME III which have added to costs without clear benefits in safety or reliability. The authors present a user's perspective on some of the relative merits and shortcomings of the nuclear codes (ASME III and XI) compared to the process industry codes (such as ASME VIII, B31.3 and API)

Operational testing of a figure of merit for overall task performance

An overall indicator or figure of merit (FOM), for the quality of pilot performance is needed to define optimal workload levels, predict system failure, measure the impact of new automation in the cockpit, and define the relative contributions of subtasks to overall task performance. A normative FOM was developed based on the calculation of a standard score for each component of a complex task. It reflected some effects, detailed in an earlier study, of the introduction of new data link technology into the cockpit. Since the technique showed promise, further testing was done. A new set of data was obtained using the recently developed Multi-Attribute Task Battery. This is a complex battery consisting of four tasks which can be varied in task demand, and on which performance measures can be obtained. This battery was presented to 12 subjects in a 20 minute trial at each of three levels of workload or task demand, and performance measures collected on all four tasks. The NASA-TLX workload rating scale was presented at minutes 6, 12, and 18, of each trial. A figure of merit was then obtained for each run of the battery by calculating a mean, SD, and standard score for each task. Each task contributed its own proportion to the overall FOM, and relative contributions changed with increasing workload. Thus, the FOM shows the effect of task changes, not only on the individual task that is changed, but also on the performance of other tasks and of the whole task. The cost to other tasks of maintaining constant performance on an individual task can be quantified.

Thermoelectric-figure-of-merit enhancement of silicon-germanium through nanocomposite concept

Science.gov (United States)

Wang, Dezhi

SiGe alloy has been the thermoelectric material element of RTGs (Radioisotope thermoelectric power generators) for more than 20 years because of its good performance at high temperature. It also has a very high potential application in converting exhaust heat into useful electricity, which currently attracts a lot of research interest in the automotive industry where 40% of the energy was rejected as exhaust heat. However, its low conversion efficiency (8%) is a major concern although it is the best in practice. A new concept, namely Si-Ge nanocomposite, was proposed to enhance thermoelectric figure-of-merit. Fast heating pressure sintering was found to be an appropriate synthesizing method and a lab-made direct current-induced hot press system was established. It can reach l200°C within several minutes and many parameters can be controlled. The uniquely designed graphite die assembly can stand l60MPa pressure which is better than the best commercial products (127MPa). Numerous Si-Ge nanocomposite samples were pressed using our DC hot press. Fully dense n-type Si-Ge nanocomposite samples of nanoSi80nanoGe20P were finally obtained. The nanocomposite structure was characterized via XRD, SEM, EDS, and TEM. The proposed nanocomposite structure, dots in a matrix, was observed. Most importantly, the thermoelectric property measurements showed that the Si-Ge nanocomposite of n-type nanoSi80nanoGe20 possessed higher electrical conductivity but lower thermal conductivity, thus a higher ZT than that of n-type nanoSi80microGe20. This result proved that thermoelectric-figure-of-merit enhancement through the nanocomposite concept was the right direction.

Merits of CMOS/SIMOX technology for low-voltage SRAM macros

CERN Document Server

Kumagai, K; Yamada, T; Nakamura, H; Onishi, H; Matsubara, Y; Imai, K; Kurosawa, S

1999-01-01

A 128-kbit SRAM (static random access memory) macro with the 0.35 mu m FD (fully-depleted) CMOS/SIMOX (separation by implantation of oxygen) technology has been developed to demonstrate the merits of that technology for low-voltage $9 applications. Its access time at Vdd =1.5 V was comparable with that obtained with the 0.35 mu m standard bulk CMOS technology at Vdd=3.3 V, due to the combination of the small S/D capacitance and the small back-bias effect. As the $9 yield of the 128-kbit SRAM macros was almost the same as the standard bulk CMOS technology, the manufacturability of the 0.35 mu m FD-CMOS/SIMOX technology has also been demonstrated.

Thermoelectric coolers with figure of merit (ZT) close to unity at low temperatures are the need of the hour with new advances in high temperature superconductors, superconducting microelectronic circuits, quantum computers, and photonics. Here, we demonstrate that the conducting polymer polyaniline (Pani) doped with camphor sulfonic acid synthesized in semi-crystalline nanostructures, possesses a giant Seebeck effect at low temperatures. The resulting enormously large Seebeck coefficient (up to 0.6 V/K) combined with an intrinsically low electrical conductivity and thermal conductivity give rise to a ZT = 0.77 at 45 K and ZT = 2.17 at 17 K.
