  1. REALISMO POÉTICO" DE PABLO NERUDA: LA "ODA A UN ALBATROS" Y "EL ALBATROS" DE BAUDELAIRE

    Full Text Available La comparación de la "Oda a un albatros viajero" de Pablo Neruda (Tercer libro de las odas con el poema "El albatros" de Baudelaire sirve para mostrar la diferencia esencial entre ambos poetas. Neruda conocía bien a Baudelaire y ciertamente lo admiraba, pero cuando en 1956 escribió su poema sobre el albatros no intentó, a la manera de Baudelaire, usar el ave como un símbolo del poeta, sino procuró describir el admirable vuelo tal cual es en la realidad. Puede, por lo mismo, ser llamado un "poeta realista", a pesar de las restricciones con que ocasionalmente se refirió a este concepto. De hecho, la carrera poética de Neruda no culminó en el compromiso político, sino se orientó a lo que justamente se puede llamar realismo poético (o naturalismo, la principal característica de sus "Odas elementales".A comparison of Neruda's Ode to a travelling Albatross ("Oda a un albatros viajero" in his Tercer Libro de las Odas with Baudelaire's poem, "The Albatross", shows the essential difference between there two poets. Neruda was well acquainted with Baudelaire and there is no doubt he admired the French poet, but when in 1956 he wrote his poem on the albatross, his idea was not to use the bird as a symbol for the poet, but to describe its marvellous flight as it really is. For this reason, Neruda can be considered as "a realist poet", despite the restrictions he himself made to the concept on different occasions. Neruda's poetical development did not, en fact culminate only in a political commitment, but was oriented to what in strict justice can be called poetic realism (or naturalism the main characteristic of his "Elementary Odes"

    Full Text Available La teoría de la conversión poética y política de Pablo Neruda durante la Guerra Civil española sugiere que la poesía del Premio Nobel chileno antes de este evento carecía de significación política, mientras que su poesía posterior fue orientada por una ideología marxista. En este artículo exploro el desarrollo de la temprana consciencia social de Neruda en su poesía y prosa escritas antes de la publicación de Crepusculario en 1923. El término que empleo para caracterizar sus creencias políticas es "la justicia social," y le presto atención especial al papel del tío de Neruda, Orlando Mason, en su formación.The theory of Pablo Neruda's poetic and political conversion during the Spanish Civil War suggests that the poetry of the Chilean Nobel Laureate prior to this event was devoid of any political significance, while his subsequent poetry was oriented by his Marxist ideology. In this article I explore the development of Neruda's early social consciousness in his poetry and prose written prior to the publication of Crepusculario in 1923. The term I use to characterize his political beliefs is "social justice," and I pay special attention to the role of Neruda's uncle Orlando Mason in his formation.

    2004-11-01

    Full Text Available Uno de los aspectos menos estudiados de la escritura nerudiana es la producción primera del joven Neruda, quien en esos años se llamaba Neftalí Reyes17. Sus primeros escritos son decisivos para la conformación del ser americano y para la constitución del sistema de referencias míticas de la escritura nerudiana, como asi mismo del proceso de nominación de la madrasta como madre y del yo como sujeto poético. Pablo Neruda publicó más de seis mil páginas en verso y en prosa. El primerísimo texto conservado del joven Neftalí Reyes se contrapone abruptamente al que es, reputadamente, el último poema de Pablo Neruda, escrito, casi con seguridad, después del 11 de septiembre de 1973. "Hastaciel" es un poema único, por la complejidad de sus imágenes, su lenguaje hermético y lo funesto de su visión. Es reconocido que la poesia póstuma de Neruda ha sido también poco explorada. En este caso, más que hacer un estudio comparativo de ambos textos, interesa examinar el comienzo y fin de una escritura, es decir, la apertura y cierre de la palabra poética, sin ignorar la ingente cantidad lírica acumulada entre ambos extremosOne of the least studied aspects of the Nerudian canon is the earliest production of the young poet then named Neftalí Reyes. The early writing of the poet is decisive for the formation of the idea of the American self and for the constitution of a system of mythical references as well as for the process of the nomination of the stepmother as the mother and the self as poetic subjects. In the course of his life, Neruda published more than six thousand pages of prose and verse. The earliest known text by the young Neftalí Reyes is in marked contrast to the poet's last poem, written with certainty after Sept. 11.1973, "Hastaciel" is a unique poem, for the complexity of its imagecy, its hermetic language, and its dark vision. It is well acknowledged that the poet's last work has not been given much study. In this case

Aunque la obra ha sido ampliamente escrutada y examinada -convertido ya el documento en "monumento"-, tanto el proceso generativo como su correlato sociocrítico no han sido suficientemente ponderados para abordar los dispositivos y procedimientos que co-construyen la segunda publicación del vate.

Tras los cinco difíciles años que había vivido como cónsul honorario de su país en distintos lugares del Asia oriental, Neruda había regresado en abril de 1932, y había dedicado sus primeros esfuerzos a preparar la nueva edición de Veinte poemas de amor y una canción desesperada que la Editorial Nascimento publicó en Santiago en junio del mismo año, con la reelaboración de varios poemas, en especial el 2 y el 4, y la sustitución del 9 por otro escrito en aquellas fechas. Antes de llegar ya había completado el volumen que en 1933 constituyó la edición inicial de Residencia en la tierra, también realizada por Nascimento tras los fracasados esfuerzos de Rafael Alberti para que se publicara en España o en Francia, allí con la colaboración de Alejo Carpentier, cuando en París éste dirigía para la argentina Elvira de Alvear la revista Imán, cuyo único número apareció el 1 de abril de 1931.

Si les questions du déficit de la balance commerciale et des droits de la propriété intellectuelle faisaient déjà débat pendant la présidence de Bill Clinton, en revanche les questions financières de la valeur du renminbi et des réserves chinoises de bons du Trésor sont apparues pendant les années Bush. Alors que l’administration Bush prônait initialement une stratégie de « congagement » (endiguement/ engagement et définissait la Chine comme un « concurrent stratégique », non seulement le 11-Septembre a modifié les priorités immédiates de Washington mais, du fait de l’interdépendance économique sino-américaine, il semble que la « dissuasion économique » soit désormais la seule stratégie réaliste dans les relations entre Washington et Pékin.During the presidency of George W.

If trade imbalance and intellectual property rights were already matters for debate during the presidency of Bill Clinton, the issues of the value of the renminbi and of Chinese holdings of US Treasury bonds emerged during the Bush years. While the Bush administration had initially advocated a strategy of “congagement” (containment/ engagement and had defined China as a “strategic competitor”, not only did 9/11 change Washington’s immediate priorities, but, with the US-China economic interdependency, the only realistic strategy between Washington and Beijing seemed to consist in “economic deterrence.”

We establish a first approach to Neruda’s Elementary Odes form the phenomenological perspective of the objects, the consideration of poetic language and its contributions to communication (Bousoño maintains that “poetry is the type of communication, established by using new words, of a very special kind of knowledge”. Objects that look at and converge toward men, everyday life objects, objects from warm and nearby environments: the construction of objectivity kingdom, “metaphor provider”. A whole poetic inventory from the “at hand” world, from proxemics, an account and a chronicle of the poet’s experience, which is dialogic, and of the heritage of the common experience. Polisemic objects, which express, inform and say “structured sygn systems”.Quiere situarse el presente estudio en una línea de investigación sobre lenguajes elaborados y teoría de la comunicación, en la que se incluyen estudios sobre la obra poética de Octavio Paz y sobre el pensamiento de Gadamer en torno al lenguaje y a la obra de arte.

    Full Text Available The Sinos River basin is located Northeast of the state of Rio Grande do Sul (29º 20' to 30º 10' S and 50º 15' to 51º20'W, Southern Brazil, covering two geomorphologic provinces: the Southern plateau and central depression. It is part of the Guaíba basin and has an area of approximately 800 km², encompassing 32 municipalities. The objective of this study was to monitor water quality in the Sinos River, the largest river in this basin. Water samples were collected at four selected sites in the Sinos River, and the following parameters were analysed: pH, dissolved oxygen, biochemical oxygen demand (BOD5, turbidity, fecal coliforms, total dissolved solids, temperature, nitrate, nitrite, phosphorous, chromium, lead, aluminum, zinc, iron, and copper. The results were analysed based on Resolution No. 357/2005 of the Brazilian National Environmental Council (CONAMA regarding regulatory limits for residues in water. A second analysis was performed based on a water quality index (WQI used by the Sinos River Basin Management Committee (COMITESINOS. Poor water quality in the Sinos River presents a worrying scenario for the region, since this river is the main source of water supply for the urban core. Health conditions found in the Sinos River, mainly in its lower reaches, are worrying and a strong indicator of human activities on the basin.

    Full Text Available Faisant suite à l’idée de Paul Mus concernant l’existence d’une « religion cadastrale » constitutive de l’organisation socio-religieuse du « socle asien », nous proposons d’approcher de manière comparative les rituels liés à la prospérité du territoire des populations vivant en marge des pouvoirs étatiques des régions sinisées et indianisées, ce que nous appelons ici les « marges sino-indiennes ». Ces rituels s’organisent autour d’un schéma récurrent dont nous analysons les détails et les variantes. Il s’agit d’une force du lieu, naturelle et sauvage, pacifiée par un ancêtre fondateur, lequel en devient avec ses descendants les sacrificateurs représentant la communauté toute entière. En légitimant l’occupation d’un espace par un groupe et en favorisant sa fertilité, ces rituels sont le lieu de cristallisation de nombreux enjeux imbriqués qui impliquent tout à la fois les sources de la subsistance, la légitimité d’occuper un territoire, mais aussi les formes d’appartenance et l’exercice du pouvoir interne au groupe et dans sa relation avec ses voisins et les centres de pouvoir qui les englobent.Taking Paul Mus’s idea of a “cadastral religion” as part of the socio-religious organisation of the “Asian base” further, we propose approaching rituals linked to the territorial prosperity of groups living on the margins of state power in the Chinese and Indian worlds in a comparative way.

Dimitrie Onciul 23e25, Sector 2, 024053 Bucharest, Romania Razelm-Sinoe Lagoon System, situated in the NW part of the Black Sea, in tight connection with the Danube Delta, has been subject to major changes due to human interventions in the past century. These changes have resulted into a complete change of the Lagoon specific ecosystems compared to its pristine state. In its natural state, as brackish - transitional environment, Antipa (1894) mentions Razelm Lagoon as one of the places with the greatest fisheries around the Black Sea coast (about 1879 - 1884, there were approximately 10,000 fishermen, all working on the Razelm Sinoe Lagoon System). Starting with the end of the XIXth Century, new canals were dug and existing channels were dredged in order to develop tighter connections with the Danube River. The natural inlet of Portita was blocked four decades ago and connections between the various parts of the lagoon system were controlled by the building of locks and sluices. The 2 inlets of Sinoe Lagoon were also controlled during early 1980s. Under these conditions, the lagoon ecosystem changed from brackish towards freshwater, with major effects on the existing flora and fauna. The period of brutal interventions ended in 1989 and the Razelm-Sinoe Lagoon System became part of the Danube Delta Biosphere Reserve in 1991, with a strict policy of nature protection and restoration. Spatial planning has been the major management option for the entire reserve, lagoon system included. Plans for sustainable development of the Razelm-Sinoe Lagoon System have been built in a participative manner, involving the local stakeholders, as part of FP7 ARCH project. Special attention has been given to impacts of climate change. The study presents the vision for the development Razelm-Sinoe Lagoon System over

    2004-01-01

    The article analyzes the role played by process ambiguities in Sino-Danish business negotiations. Process ambiguities refer to perceived expectational inconsistencies concerning (1) appropriate forms of behavior; (ii) attributional judgments; and (iii) structuring of the negotiation process....... These ambiguities stem from differences in negotiation scripts across Danish and Chinese cultures. The essential argument being advanced here is that it is the effective and/or the ineffective management of process ambiguities that shapes the evolution of the negotiating dynamic between the Danish and the Chinese...... businesspeople. An inductive model of sino-Danish negotiations is developed that is based on 24 interviews conducted with Danish expatriate managers in China and 4 interviews with Chinese working in Danish companies. Implications for research and practice are discussed...

    The present study aimed to evaluate the physicochemical parameters and the genotoxic potential of water samples collected in the upper, middle, and lower courses of the Sinos River, southern Brazil. The comet assay was performed in the peripheral blood of fish Hyphessobrycon luetkenii exposed under laboratory conditions to water samples collected in summer and winter in three sampling sites of Sinos River. Water quality analysis demonstrated values above those described in Brazilian legislation in Parobé and Sapucaia do Sul sites, located in the middle and in the lower courses of the Sinos River, respectively. The Caraá site, located in the upper river reach, presented all the physicochemical parameters in accordance with the allowed limits in both sampling periods. Comet assay in fish revealed genotoxicity in water samples collected in the middle course site in summer and in the three sites in winter when compared to control group. Thus, the physicochemical parameters indicated that the water quality of the upper course complies with the limits set by the national guidelines, and the ecotoxicological assessment, however, indicated the presence of genotoxic agents. The present study highlights the importance of combining water physicochemical analysis and bioassays to river monitoring.

    Full Text Available Después de experimentar las etapas del desarrollo espontáneo y del desarrollo independiente, las  relaciones sino-latinoamericanas han entrado en una nueva fase del "desarrollo constructivo" que se caracteriza por el objetivo estratégico de construir una nueva estructura y una comunidad de destino común, un con un nuevo marco de cooperación basado en la negociación y en la ganancia mutua. Como resultado de esto, los lazos entre China y América Latina han conseguido muchos avances en los terrenos político, económico, cultural y de la cooperación multilateral. Sin embargo, debido a la incertidumbre del mundo y las transformaciones de las dos partes, la cooperación entre ambos lados sigue enfrentando muchos desafíos. En la actualidad, hay varias contradicciones importantes que deben ser resueltas: la primera es la brecha entre el mejoramiento de mecanismos de cooperación y sus expectativas; la segunda es la cada vez más fuerte presencia estratégica de China en América Latina y la capacidad de aceptación de este continente. La última es la necesidad urgente de desarrollar y profundizar esta relación tras la falta del conocimiento mutuo.

  19. Sinos River Hydrographic Basin: urban occupation, industrialization and environmental memory

    Directory of Open Access Journals (Sweden)

    M. F. Nunes

    Full Text Available This article presents an analysis of the process of industrialization and urbanization of the Sinos Valley in Rio Grande do Sul state, Brazil, starting from the establishment of leather goods and footwear manufacturing in the region during the 19th century when tanneries and factories producing footwear and/or components for footwear began to appear, and with special attention to aspects related to the environmental impact on the Sinos river hydrographic basin. The article is based on both bibliographic and documentary research and also draws on biographical narratives of workers with links to the leather goods and footwear industry obtained using ethnographic method. It was found that contemporary environmental conflicts emerge from within a memory of work and an environmental memory in which the factories, the unplanned urbanization, and the utilization of water and other natural resources form a chain of significance. Significance that precludes any form of fragmented analysis that isolates any of these aspects from the others: the economic, socio-historic, cultural, political, or the environmental.

    The paranasal sinus infections caused by Aspergillus spp. are usually presented clinically with mild symptoms, however they may lead to invasive disease and mortality especially in immunocompromised individuals. In this report a fatal case of sino-orbital aspergillosis developed in an immunocompetent patient has been presented. Seventy-four years old female patient was admitted to the hospital with the complaints of fever and progressively increasing headache that continued for 15 days. Due to the development of nausea, vomiting, loss of consciousness and stiff neck in the following days, cerebrospinal fluid (CSF) sample was obtained. Direct microscopic examination of the Gram and acidfast staining of the CSF sample revealed no microorganisms, no growth was detected in CSF culture and PCR amplification was negative for Herpes simplex virus and Mycobacterium tuberculosis. Since no response was achieved by empirical ceftriaxone, ampicillin and conventional anti-tuberculosis treatment and tachypnea, proptosis and progressive respiratory failure developed in the patient, she was transferred to the intensive care unit. The radiological examination revealed soft tissue lesion filling the sphenoid sinus, extending to the nasal cavity and suprasellar cistern, destruction of bones, dilated orbital vein, cavernous sinus thrombosis and infarction on left cerebral peduncule. Patient was operated and pus and fungus ball were aspirated from the openings of both sphenoid sinuses. Gomori methenamine silver, periodic acid-Schiff and haematoxylin-eosine staining of the operational material exhibited dichotomously branching hyphae. The patient was diagnosed as invasive sino-orbital aspergillosis based on the clinical, radiological and histopathological findings. Despite antifungal therapy and surgical debridement, the patient died. It should always be kept in mind that aspergillosis can develop in immuncompetent individuals. Delay in diagnosis and treatment may lead to fatality. Thus

    Worldwide environmental pollution is increasing at the same rate as social and economic development. This growth, however, is disorganized and leads to increased degradation of water resources. Water, which was once considered inexhaustible, has become the focus of environmental concerns because it is essential for life and for many production processes. This article describes monitoring of the water quality at three points along the Sinos River (RS, Brazil), one in each of the upper, middle and lower stretches. The points were sampled in 2013 and again in 2014. The water samples were analyzed to determine the following physical and chemical parameters plus genotoxicity to fish: metals (Cr, Fe, Al), chemical oxygen demand, biochemical oxygen demand, chlorides, conductivity, total suspended solids, total phosphorous, total and fecal coliforms, pH, dissolved oxygen, turbidity, total Kjeldahl nitrogen nitrate and ammoniacal nitrogen. Genotoxicity was tested by exposing individuals of the species Astyanax jacuhiensis to water samples and then comparing them with a control group exposed to water from the public water supply. The results confirmed the presence of substances with genotoxic potential at the sample points located in the middle and lower stretches of the river. The results for samples from the upper stretch, at P1, did not exhibit differences in relation to the control group. The physical and chemical analyses did not detect reductions in water quality in the lower stretch, as had been expected in view of the large volumes of domestic and industrial effluents discharged into this part of the river.

  10. The contemporary dynamics of Sino-Indian relations: Examining maritime security, economics, energy and elite dialogue

    Science.gov (United States)

    Athwal, Amardeep

    This dissertation examines the modern-day dynamics of the Sino-Indian relationship---with a particular focus on issues relating to maritime security, economics, energy and elite bilateral dialogue. In exploring the contemporary nature of the Sino-Indian relationship, the dissertation also seeks to assess the accuracy of predominant neorealist accounts of the Sino-Indian relationship. Since the 1962 Sino-Indian War, most analysts have continued to emphasize the conflictual and competitive elements within the Sino-Indian relationship. The dissertation first explores the crucial post-independence history of Sino-Indian relations to provide the appropriate contextual background (chapter one). Thereafter, the dissertation explores the geopolitical significance of the Indian Ocean in light of soaring (global) energy demands. This then leads into an analysis of China and India's naval modernization and China's strategic partnership with Pakistan and Myanmar (chapter two). While acknowledging the credibility of neorealist insights in the realm of maritime security by detailing China and India's naval buildup and naval strategy, overall, it is found that the security dilemma argument is overstated. There is both a lack of threat perception and the existence of alternate explanations for both Chinese and Indian activities in Southern Asia. The dissertation then moves on to explore the positive elements within the Sino-Indian relationship---growing economic interdependence, energy convergence and elite consensus. In the economic realm (chapter three) it is found that Sino-Indian bilateral trade is increasingly being framed institutionally and rapidly expanding every year. The areas where the Sino-Indian economic relationship could be fruitfully expanded are traced and the great potential of bilateral trade is discussed. Thereafter, the dissertation highlights how China and India are beginning to coordinate energy policy (chapter four) as well as the growing political will

    en la cirugía tenian origen en los descubrimientos de la Era Industrial.

    Así como la Era Industrial se desvanece también lo hace la edad dorada de la cirugía. La Era Industrial se ve ahora reemplazada por la Era de la informática y la cirugía convencional se ve reemplazada por nuevos procedimientos minimamente invasivos o no invasivos.

    Estamos ahora en la mitad de una transición y no es claro todavía como parecerá la nueva generación de la medicina y la cirugía pero la tendencia es de procedimientos altamente inteligentes, miniaturizados que han progresado de la cirugía minimamente invasiva a la cirugía no invasiva y cuyo desarrollo depende del progreso de la informática.

    La cirugía convencional no va a desaparecer del todo y algunos procedimientos se refugiaran en un nicho, pero los procedimientos no invasivos van a predominar.

    La cirugía laparoscópica o minimamente invasiva no es el punto final, sino más bien una fase de transición entre la cirugía abierta y las formas emergentes de procedimientos no invasivos guiados por imágenes.

    La cirugía laparoscopica fue el evento semilla que disparó el despertar de la Era de la Informática.

    Para que ocurra una revolución todas las facetas de una disciplina deben ser contempladas, no simplemente una sola especialidad como la cirugía. Una revolución debe también reflejar los mismos cambios que se presentan en otras áreas cientificas y en la sociedad como un todo. Debe ser consistente con las predicciones globales que han sido enunciadas tales como “la tercera ola de Alvin Toffler ó los “Megacambios” de John Naisbitt. Y más importante aún con el “Ser Digital” de Nicolas Negroponte.

    Los dos primeros autores nos dieron una mirada al poder y la magnitud de esta revolución, pero fue el concepto de Negroponte “de bits en lugar de atomos” lo que completó el cambio. Negroponte hizo énfasis en que anteriormente se requería el uso de objetos f

    Full Text Available Language choice in mixed marriages plays a crucial role in language maintenance. It helps in maintaining at least one or two languages from generation to generation. In this study an examination on the language choice of some Sino-Indian Malaysians in Kuala Lumpur, Malaysia, is explored to find out the language choice in a range of domains and with different speech partners. Sino-Indians are the offspring of marriages between Indians and Chinese. There were 30 participants consisting of 14 males and 16 females who took part in the study. A questionnaire consisting of 89 items was administered to the participants who were working or studying in Kuala Lumpur at that time. The findings reveal that language choice in some Sino-Indian families is influenced by factors such as age, domains of communication, attitudes towards the language, and identity. Age plays an important role in lan¬guage choice, particularly in the home domain. Some older Sino-Indian speakers are bilingual in English and Malay, the middle-aged speakers are trilingual and speak more in English and some Tamil and Chinese, and the younger speakers are multilingual but favour the use of English. This study has also examined how the Sino-Indian respondents viewed their dual heritage.

    1992-02-01

    Geometry optimization and harmonic vibrational analysis for the three isomers of SiNO were carried out at three levels of ab initio SCF calculations (ROHF, UHF and MCSCF) with 6-31G, 6-31G* and TZP basis sets using the GAMESS program (NDSU version). With d functions, each of the isomers, SiNO, OSiN and SiON, has a linear conformation with a 2Π ground state in all three levels of theory. The isomers SiNO and OSiN are found to be close in energy, while SiON, lying higher in energy, seems to be an unstable complex. To examine the possibility of the optical detection of SiNO isomers, the potential energy surfaces were calculated with CI/TZP by using our MOLYX-QDCI program. The nature of chemical bonds in the SiNO isomers and the possibility of any of the isomers being the new radical recently detected in space are discussed.

    Full Text Available Energy cooperation is an important component in the Sino-Russia relationship. After more than a decade of efforts, China and Russia have made great progress in their cooperation in the area of oil and natural gas, which has not only promoted the economic developments in both countries, but also expanded their common interests to a large extent, resulting in a tremendous improvement of the two countries’ international strategies towards each other. Nevertheless, constrained and influenced by the evolution of contemporary international politics and economies, the Sino-Russia energy cooperation is facing some problems and barriers. Therefore, the aim of this article is to analyze the multiple elements affecting the Sino-Russia energy cooperation through the prism of Neo-realism, Neo-liberalism and Social Constructivism, hence a clear account of the opportunities and challenges that constitute this cooperation will be gained.

  19. The absent father of Sino-French cinema: Contemporary Taiwanese cinema and 1950s French auteurs

    © 2014 Taylor & Francis. In contemporary Sino-French cinema, father characters who are dead, long lost or geographically distant leave gaping holes in the lives of the offspring left behind. The absent fathers in Sino-French films by Taiwanese auteurs Cheng Yu-chieh, Hou Hsiao-hsien and Tsai Ming-liang serve as metaphors for French auteurs. French New Wave films constitute the majority of the intertexts; however, early 1950s French cinema and even late nineteenth-century painting reflect th...

    Full Text Available La definición de la Psicología como ciencia de la conducta adoptada por el Conductismo supone e implica a su vez una conceptualización clara y unívoca de dicho concepto. Pero tal definición se enfrenta con una serie de malentendidos tenaces que dificultan no sólo la comprensión de dicho concepto básico sino también, en consecuencia, la propia conceptualización conductista. El propósito del presente trabajo es intentar exponer algunos de estos malentendidos, entre los que destacan los errores categoriales groseros, los procesos de reificación abusiva, los razonamientos tautológicos disfrazados, la generalización imprudente del modelo médico al ámbito de la conducta y la confusión nefasta entre un fenómeno y su conceptualización. Para ello, y con un tono más didáctico que académico, se recurre a una serie de metáforas de la vida cotidiana: la parte escondida del iceberg no es más que iceberg, las piedras no caen por su propio peso, los hombres y las mujeres no mueren porque son mortales, el bacilo de Koch existe y la máscara no es el rostro.

  6. History of water quality parameters - a study on the Sinos River/Brazil.

    Water is increasingly becoming a valuable resource, constituting one of the central themes of environmental, economic and social discussions. The Sinos River, located in southern Brazil, is the main river from the Sinos River Basin, representing a source of drinking water supply for a highly populated region. Considering its size and importance, it becomes necessary to conduct a study to follow up the water quality of this river, which is considered by some experts as one of the most polluted rivers in Brazil. As for this study, its great importance lies in the historical analysis of indicators. In this sense, we sought to develop aspects related to the management of water resources by performing a historical analysis of the Water Quality Index (WQI) of the Sinos River, using statistical methods. With regard to the methodological procedures, it should be pointed out that this study performs a time analysis of monitoring data on parameters related to a punctual measurement that is variable in time, using statistical tools. The data used refer to analyses of the water quality of the Sinos River (WQI) from the State Environmental Protection Agency Henrique Luiz Roessler (Fundação Estadual de Proteção Ambiental Henrique Luiz Roessler, FEPAM) covering the period between 2000 and 2008, as well as to a theoretical analysis focusing on the management of water resources. The study of WQI and its parameters by statistical analysis has shown to be effective, ensuring its effectiveness as a tool for the management of water resources. The descriptive analysis of the WQI and its parameters showed that the water quality of the Sinos River is concerning low, which reaffirms that it is one of the most polluted rivers in Brazil. It should be highlighted that there was an overall difficulty in obtaining data with the appropriate periodicity, as well as a long complete series, which limited the conduction of statistical studies such as the present one.

    Most of the orbital osteomas arise from the adjacent paranasal sinuses. Some of them may contain osteoblastoma-like areas and may be misdiagnosed as osteoblastoma, both radiologically as well as histopathologically. Sino-orbital osteomas with osteoblastoma-like features show a typical radiological appearance. They have a distinct zonal pattern, in which less dense osteoblastoma-like areas are located at the base of the lesion and dense mature bone is located at the periphery. These broad-based bone lesions also have a tendency for extracavitary polypoid growths from the paranasal sinus into the adjacent orbit. We report here the CT and MR imaging findings of three cases with sino-orbital osteoma with osteoblastoma-like features. (orig.)

    The aim of this study was to determine the feasibility of combining water quality analysis with different biomarkers to characterise the relationship between anthropogenic contamination and biotic response in the Sinos River, southern Brazil. Wistar rats were studied using three biomarkers combined with physical, chemical and microbiological analysis to assess the effects of pollution at four sampling sites. The induction of oxidative stress was quantified by MDA levels in peripheral blood, lymphocyte DNA damage was determined using the comet assay, and histopathological changes were analysed in the liver. After sampling, animals were allowed to drink the river water during a 48 hours period. No increase in oxidative stress and DNA damage was observed. However, liver damage was observed in the animals exposed to water samples, indicating that the Sinos River is contaminated with hepatotoxic substances. Water analyses confirmed that water quality decreased downriver.

  17. The Limits of Interdependence: Cooperation and Conflict in Sino-Japanese Relations

    Directory of Open Access Journals (Sweden)

    Adam Eldridge

    2014-01-01

    Full Text Available Since the introduction of Deng Xiaoping’s Open Door policy in 1979, the value and complexity of Sino-Japanese economic ties have grown exponentially. However, even as economic ties have developed, security relations have deteriorated as perceptions of a ‘China threat’ and a ‘re-militarised Japan’ have emerged in Tokyo and Beijing. The simultaneous existence of these trends challenges international relations theory. Economic interdependence theories expect that the development of economic relations reduces the role of security in bilateral relations. Conversely, neorealist theories posit that, given the preeminence of national security, a perception of threat will cool economic relations. Sino-Japanese economic relations have demonstrable bilateral benefits. Additionally, economic relations have created interest groups invested in maintaining good relations. These groups have successfully managed economic friction points and integrated bilateral trade. However, economic interdependence seems not to translate to the security calculus confirming neorealism’s contention that national security is preeminent. In particular, Japan’s development of Ballistic Missile Defence (BMD illustrates the insignificance of economic ties in security planning. That said, it is equally true that perceptions of threat appear to have little influence on bilateral economic interdependence. Therefore, Sino-Japanese relations are best described by applying interdependence and neorealist theories in a complementary approach.

    Full Text Available El levantamiento chiapaneco del primero de enero de 1994 descencadenó la movilización de varios sectores de la sociedad mexicana. Del repudio unánime a la guerra nació un amplio movimiento ciudadano y popular que –sin compartir los medios tácticos de la lucha armada– convergió con el Ejército Zapatista de Liberación Nacional (EZLN en sus aspiraciones sociales y políticas: la lucha por la democracia, la justicia y la libertad. Por ser él, resulta pertinente calificarlo con el término de neozapatismo civil. Si sumamos a este conjunto de movilizaciones ciudadanas y populares el propio zapatismo armado – advirtiendo su carácter «socio-políticomilitar »– obtendremos el neozapatismo en su sentido más amplio. Otra forma de entender el neozapatismo –que desarrollaremos en la presente reflexión– es como un proceso dinámico constituido por una pluralidad de intereses, voluntades e identidades, que lo inscriben dentro de un campo de contradicciones y de tensiones no resueltas. Como primera premisa podemos apuntar que el neozapatismo no es ni homogéneo ni mucho menos monolítico, sino que, como lo mostraremos a continuación, tiene una naturaleza multifacética, polisémica y fluídica.

    Aggressive measures were instituted by the Beijing municipal authorities to restrict vehicular traffic in the Chinese capital during the recent Sino-African Summit. We show that reductions in associated emissions of NOx were detected by the Dutch-Finnish Ozone Monitoring Instrument (OMI) aboard the Aura satellite. Interpretation of these data using a 3-dimensional chemical transport model indicates that emissions of NOx were reduced by 40% over the period of November 4 to 6, 2006, for which the restrictions were in place.

    Full Text Available Fragmented production means organization of production in which different stages of production are divided among different suppliers that are located in different countries. East Asia is one of the most important manufacturing centers in the world, China imports components from other East Asian economies for processing and then exports to the United States. The volume of export from China to the United States increase in traditional international trade statistics. Therefore, the solution of Sino-U.S. trade imbalance should pay attention to the relationship between the United States, China, and other East Asian economies.

    2004-11-01

    Full Text Available Este ensayo pretende identificar y estudiar cierto tipo de lenguaje y sentimiento poéticos, de origen y resonancia bíblica, derívada del último libro del Nuevo Testamento, el Apocalipsis. Se encuentra en Residencia una experiencia del mundo en un estado de crisis, hostilidad y ruina, un poderoso sentido del exilio y enajenamiento del ser humano después de la caída, y una angustia desesperada de estar viviendo los últimos días en la tierra antes del juicio fmal, antes del fin del mundo. También se señala que este sentido apocalíptico de Residencia se refuerza y se transforma en la visión poética del Canto general. En esta épica marxista y bíblica, que narra el destino de los pueblos latinoamericanos, hay un claro sentido milenario, inspirado en la Biblia, de que la historia humana ofrece esperanza y redención al final del camino de la vida. El mundo latinoamericano, golpeado por las catástrofes de la historia (colonialismo, esclavitud e imperialismo tendrá su resolución, su victoria en la lucha y defensa de los caídos. Y así la aguda y angustiada sensación del Apocalipsis (sin Dios y sin redención en Residencia, se transforma en Canto general en la fuerte convicción revolucionaria de "la justicia conquistada en la lucha", por los pueblos oprimidos como meta suprema al final de esta etapa brutal de la historia humanaThis essay intends to study and identify a certain type of poetical sentiment and language of biblical origen and resonance deriving from the last book of the New Testament, the Apocalypse. In Neruda's "Residence" we find a world experience in a state of crisis, hostility and ruin; a powerful feeling of exile and alienation of the human being after the fall, and a desperate anguish to be living the last days on earth before the end of the world. It is also mentioned that this apocalyptic sense of "Residence" is reinforced and transformed into the vision of the "Canto General'. In this biblical and marxist epic

    The Sinos River, in southern Brazil, is polluted by industrial discharges and untreated urban wastes. Fish genotoxicity biomarkers are valuable parameters for environmental risk assessment. In this study, we used the comet assay to detect genotoxicity due to multiple sources of pollution in the peripheral blood of a native fish species (Hyphessobrycon luetkenii). In addition, we analysed possible DNA damage from aluminum, lead, chromium, copper, nickel, iron and zinc contamination. Water samples were collected seasonally from three sampling sites and the fish were assessed under laboratory conditions. Water chemical analysis showed an increased level of aluminum and iron in most of the samples at sites 2 and 3, located in the middle and lower river course, respectively. The index of DNA damage assessed by the comet assay demonstrated no significant differences in different seasons or at the different sampling sites, while the frequency of cells with DNA damage was higher in water samples collected at sites 1 and 2 during the spring season. None of the metals studied seems to be associated with the increase in the frequency of cells with DNA damage observed during the spring season. The results of this study indicate that the Sinos River is contaminated with substances that are genotoxic to fish, including the waters near the river spring.

    Full Text Available Tolerance is a basic value of our democracies, when it applies to life attitudes and to symbolic interpretations of our experience. However, usually there is no tolerance about statements of fact offered without scientific basis or from assumptions that proved to be false. Religions have a symbolic and poetic dimension which is not only tolerable, but even also fruitful for the interpretation of our life, but they also tend to present themselves as explanations of facts in competition with scientific explanations. It can be argued whether complete tolerance of this second use of religious ideology should be encouraged.

    La tolerancia es un valor básico de nuestras democracias, en cuanto se refiere a actitudes vitales y a interpretaciones simbólicas de nuestra experiencia. No suele haber tolerancia, en cambio, sobre las cuestiones de hecho presentadas sin base científica o desde presupuestos comprobadamente falsos. Las religiones tienen una dimensión poética y simbólica no sólo tolerable sino hasta enriquecedora de nuestra interpretación vital, pero casi siempre pretenden presentarse también como explicaciones de los hechos en competencia con la de los científicos. Puede cuestionarse si debe haber plena tolerancia para este segundo uso de la ideología religiosa.

The comparison of mean oocyte diameters, gonadal indices and gonado-somatic relationships of specimens captured in polluted areas with individuals from unpolluted reference sites revealed a significant decrease of these parameters with increasing water pollution. High loads of organic and industrial sewage are considered responsible for these effects. Condition factors showed an inverse relationship, and increased significantly in downriver polluted areas. The declining gonadal indices showed that energy was allocated to somatic growth. The results of the study recommend the use of A. fasciatus in biomonitoring essays.

    2013-10-01

    The paper presents a Sino-Finnish teaching initiative, including the design and experiences of a series of pedagogical workshops implemented at the Aalto-Tongji Design Factory (DF), Shanghai, China, and the experimentation plans collected from the 54 attending professors and teachers. The workshops aimed to encourage trying out interdisciplinary hands-on teaching, and enable teachers to implement their ideas for teaching development utilising the DF pedagogical platform. The majority of the participants planned teaching experimentations aiming at enhancing student understanding of curricula through various group exercises utilising concrete artefacts, but found their implementation within established practices quite challenging, highlighting the challenges of transforming strategic collaboration into grass-root activity. However, the workshops ignited widespread interest in a continuum of collaboration in teaching development, and the DF has since acted as a hub for the implementation of subsequent internationalisation efforts of the two universities, including establishing a dual-degree programme.

  16. Imperial Japanese Army Intelligence in North and Central China During the Second Sino-Japanese War

    Full Text Available The Japanese today seek to improve their national intelligence apparatus, particularly in relation to human intelligence assets and higher echelon coordination. To be successful, Japan must examine its wartime past in the intelligence field. The Imperial Japanese Army maintained a prolific intelligence presence in North and Central China during the Second World War. Its intelligence apparatus encompassed all aspects of information collection, with considerable overlap between intelligence organisations in an effort to avoid gaps in intelligence coverage. Japan’s intelligence system in North and Central China was nevertheless inefficient, exacerbated by inherent weaknesses and reactive rather than proactive alterations throughout the course of the conflict. This paper examines this lack of efficacy within Japan’s intelligence system during the Second Sino-Japanese conflict, and the efforts made to overcome difficulties faced by Japanese intelligence in North and Central China throughout this period.

  17. Cooperation is related to dispersal patterns in Sino-Tibetan populations

    There is growing recognition in both evolutionary biology and anthropology that dispersal is key to establishing patterns of cooperation. However, some models predict that cooperation is more likely to evolve in low dispersal (viscous) populations, while others predict that local competition for resources inhibits cooperation. Sex-biased dispersal and extra-pair mating may also have an effect. Using economic games in Sino-Tibetan populations with strikingly different dispersal patterns, we measure cooperation in 36 villages in southwestern China; we test whether social structure is associated with cooperative behaviour toward those in the neighbourhood. We find that social organization is associated with levels of cooperation in public goods and dictator games and a resource dilemma; people are less cooperative towards other villagers in communities where dispersal by both sexes is low. This supports the view that dispersal for marriage played an important role in the evolution of large-scale cooperation in human society. PMID:26478534

    Full Text Available Antibiotic resistance is a complex global health challenge. The recent Global Action Plan on antimicrobial resistance highlights the importance of adopting One Health approaches that can cross traditional disciplinary boundaries. We report on the early experiences of a multisectoral Sino-Swedish research project that aims to address gaps in our current knowledge and seeks to improve the situation through system-wide interventions. Our research project is investigating antibiotic use and resistance in a rural area of China through a combination of epidemiological, health systems and laboratory investigations. We reflect here on the challenges inherent in conducting long distance cross-disciplinary collaborations, having now completed data and sample collection for a baseline situation analysis. In particular, we recognise the importance of investing in aspects such as effective communication, shared conceptual frameworks and leadership. We suggest that our experiences will be instructive to others planning to develop similar international One Health collaborations.

  6. A high speed compact microwave interferometer for density fluctuation measurements in Sino-UNIted Spherical Tokamak

    A single-channel 3 mm interferometer has been developed for plasma density diagnostics in the Sino-UNIted Spherical Tokamak (SUNIST). The extremely compact microwave interferometer utilizes one corrugated feed horn antenna for both emitting and receiving the microwave. The beam path lies on the equatorial plane so the system would not suffer from beam path deflection problems due to the symmetry of the cross section. A focusing lens group and an oblique vacuum window are carefully designed to boost the signal to noise ratio, which allows this system to show good performance even with the small-diameter central column itself as a reflector, without a concave mirror. The whole system discards the reference leg for maximum compactness, which is particularly suitable for the small-sized tokamak. An auto-correcting algorithm is developed to calculate the phase evolution, and the result displays good phase stability of the whole system. The intermediate frequency is adjustable and can reach its full potential of 2 MHz for best temporal resolution. Multiple measurements during ohmic discharges proved the interferometer’s capability to track typical density fluctuations in SUNIST, which enables this system to be utilized in the study of MHD activities.

    Unplanned use and occupation of the land without respecting its capacity of assimilation and environmental purification leads to the degradation of the environment and of water used for human consumption. Agricultural areas, industrial plants and urban centres developed without planning and the control of effluent discharges are the main causes of water pollution in river basins that receive all the liquid effluents produced in those places. Over the last decades, environmental management has become part of governmental agendas in search of solutions for the preservation of water quality and the restoration of already degraded resources. This study evaluated the conditions of the main watercourse of the Sinos River basin by monitoring the main physical, chemical and microbiological parameters described in the CONAMA Resolution no. 357/2005.The set of parameters evaluated at five catchment points of water human consumption revealed a river that has different characteristics in each reach, as the upper reach was class 1, whereas the middle and lower reaches of the basin were class 4. Monitoring pointed to households as the main sources of pollutants in those reaches, although metals used in the industrial production of the region were found in the samples analyzed.

    A multicentre comparative clinical study of CLa implant and Sino-implant was carried out at 100 subcentres in 11 provinces, and a total of 19673 subjects were recruited. Two year follow up has been finished. The follow-up rate at the end of two years was 94,29%. Two-year cumulative continuation rate per 100 women for Sino-implant(89.93) was significantly higher than that for CLa implant (88.89). Two-year cumulative pregnancy rates per 100 women were 0.0462(CLa implant) and 0.281(Sino-implant) respectively; there was statistically significant difference between them. No ectopic pregnancy was recorded among CLa implant users and three ectopic pregnancies were reported among Sino implant users,resulting in an ectopic pregnancy rate of 0.163 per 1000 women years. The incidence of side-effects appeared to diminish with time. The major side effects were the menstrual disturbances, which accounted for more than 90% of the total sideeffects, and the incidence of frequent menstruation, irregular bleeding and spotring was higher than that of infrequentjscanty menstruation and amenorrhea. Use of CLa implant had higher incidence of amenorrhea and infrequentjscanty menstruation than that of Sin-imptant. During two-year follow-up, the number of discontinuation due to menstrual problems contributed 78% of the total number of discontinuation; two year menstrual-related cumulative discontinuation rates were 8.96 per 100 women for CLa implant and 7.84 for Sino-implant; there was statistically significant difference(P< 0.01). Two-year study shows that the two types of implant are similar to Norplant in the incidence of side-effects and contraceptive efficacy as well as two year continuation rates.

Destaca dos "familias" distintas de sedentarios surgidas en dos momentos históricos específicos: el sedentario "cooperiano", oriundo de los preceptos de la aptitud física difundidos en Brasil al principio de los años 1970 por Kenneth Cooper; el sedentario "agitoniano", proveniente de las recomendaciones de actividad física moderada de mediados de los años 1990, propagadas de modo más evidente en Brasil por el programa Agita São Paulo. Entre tantas acepciones posibles, prevalece la noción de que el sedentarismo es agente catalizador de muchas características "malas", una plaga silenciosa, que lentamente envenena el cuerpo y debilita el alma.

    As an apex predator the Amur tiger (Panthera tigris altaica) could play a pivotal role in maintaining the integrity of forest ecosystems in Northeast Asia. Due to habitat loss and harvest over the past century, tigers rapidly declined in China and are now restricted to the Russian Far East and bordering habitat in nearby China. To facilitate restoration of the tiger in its historical range, reliable estimates of population size are essential to assess effectiveness of conservation interventions. Here we used camera trap data collected in Hunchun National Nature Reserve from April to June 2013 and 2014 to estimate tiger density and abundance using both maximum likelihood and Bayesian spatially explicit capture-recapture (SECR) methods. A minimum of 8 individuals were detected in both sample periods and the documentation of marking behavior and reproduction suggests the presence of a resident population. Using Bayesian SECR modeling within the 11 400 km(2) state space, density estimates were 0.33 and 0.40 individuals/100 km(2) in 2013 and 2014, respectively, corresponding to an estimated abundance of 38 and 45 animals for this transboundary Sino-Russian population. In a maximum likelihood framework, we estimated densities of 0.30 and 0.24 individuals/100 km(2) corresponding to abundances of 34 and 27, in 2013 and 2014, respectively. These density estimates are comparable to other published estimates for resident Amur tiger populations in the Russian Far East. This study reveals promising signs of tiger recovery in Northeast China, and demonstrates the importance of connectivity between the Russian and Chinese populations for recovering tigers in Northeast China. © 2016 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

  12. Comparison of China-US Engineering Ethics Educations in Sino-Western Philosophies of Technology.

    2015-12-01

    Ethics education has become essential in modern engineering. Ethics education in engineering has been increasingly implemented worldwide. It can improve ethical behaviors in technology and engineering design under the guidance of the philosophy of technology. Hence, this study aims to compare China-US engineering ethics education in Sino-Western philosophies of technology by using literature studies, online surveys, observational researches, textual analyses, and comparative methods. In my original theoretical framework and model of input and output for education, six primary variables emerge in the pedagogy: disciplinary statuses, educational goals, instructional contents, didactic models, teaching methods, and edificatory effects. I focus on the similarities and differences of engineering ethics educations between China and the U.S. in Chinese and Western philosophies of technology. In the field of engineering, the U.S. tends toward applied ethics training, whereas China inclines toward practical moral education. The U.S. is the leader, particularly in the amount of money invested and engineering results. China has quickened its pace, focusing specifically on engineering labor input and output. Engineering ethics is a multiplayer game effected at various levels among (a) lower level technicians and engineers, engineering associations, and stockholders; (b) middle ranking engineering ethics education, the ministry of education, the academy of engineering, and the philosophy of technology; and (c) top national and international technological policies. I propose that professional engineering ethics education can play many important roles in reforming engineering social responsibility by international cooperation in societies that are becoming increasingly reliant on engineered devices and systems. Significantly, my proposals contribute to improving engineering ethics education and better-solving engineering ethics issues, thereby maximizing engineering

    Full Text Available BACKGROUND: The Qinghai-Tibetan Plateau (QTP and its southern and southeastern mountain ranges, Himalaya-Hengduan Mountains (HHM, are one of the most extensive habitats for alpine plants in the world. How ferns occurring in QTP and HHM changed their distribution ranges in response to Quaternary climatic oscillations remains almost unknown. METHODOLOGY AND RESULTS: We employed sequences of two chloroplast DNA regions, rps4-trnS and trnL-trnF, to reconstruct phylogeography of the Sino-Himalayan fern Lepisorus clathratus, occurring mainly in the QTP and HHM. Individuals of this species have either dehiscent or indehiscent sporangia with the latter evolved from the plesiomorphic dehiscent forms. Based on a range-wide sampling, we detected 27 cpDNA haplotypes that were divided into five groups by network analyses. Populations in the Hengduan Mountains possess the highest genetic diversity, while a single haplogroup is detected across the north-central region. A distinct phylogeographical subdivision was detected between the Hengduan Mountains and north-central region by AMOVA analysis. The haplogroup distribution pattern, coalescence and AMOVA analysis suggest that a long term survival area (refugia of the species was located in the Hengduan Mountains during glaciations, with probable range expansions into north-central regions during interglacial periods. Populations with indehiscent sporangium can carry private haplotypes and are inclined to maintain genetic homogeneity. One group with indehiscent sporangia most likely survived in situ on the QTP during glaciations. CONCLUSIONS/SIGNIFICANCE: This study for the first time sheds light on the response of alpine ferns in the QTP and HHM to the Quaternary climatic oscillations.

    Aim In contrast to extensive reports on the roles of Nav1.5 α-subunits, there have been few studies associating the β-subunits with cardiac arrhythmogenesis. We investigated the sino-atrial and conduction properties in the hearts of Scn3b−/− mice. Methods The following properties were compared in the hearts of wild-type (WT) and Scn3b−/− mice: (1) mRNA expression levels of Scn3b, Scn1b and Scn5a in atrial tissue. (2) Expression of the β3 protein in isolated cardiac myocytes. (3) Electrocardiographic recordings in intact anaesthetized preparations. (4) Bipolar electrogram recordings from the atria of spontaneously beating and electrically stimulated Langendorff-perfused hearts. Results Scn3b mRNA was expressed in the atria of WT but not Scn3b−/− hearts. This was in contrast to similar expression levels of Scn1b and Scn5a mRNA. Immunofluorescence experiments confirmed that the β3 protein was expressed in WT and absent in Scn3b−/− cardiac myocytes. Lead I electrocardiograms from Scn3b−/− mice showed slower heart rates, longer P wave durations and prolonged PR intervals than WT hearts. Spontaneously beating Langendorff-perfused Scn3b−/− hearts demonstrated both abnormal atrial electrophysiological properties and evidence of partial or complete dissociation of atrial and ventricular activity. Atrial burst pacing protocols induced atrial tachycardia and fibrillation in all Scn3b−/− but hardly any WT hearts. Scn3b−/− hearts also demonstrated significantly longer sinus node recovery times than WT hearts. Conclusion These findings demonstrate, for the first time, that a deficiency in Scn3b results in significant atrial electrophysiological and intracardiac conduction abnormalities, complementing the changes in ventricular electrophysiology reported on an earlier occasion.

    For the first time, regional atmospheric simulations with spatial resolution down to 6 km have been performed in the Sino-Mongolian Altai region using the COSMO weather forecast and regional climate model. Two 5-year periods (1979-1982 and 2008-2012) have been simulated for a first evaluation of the model in this special region. The added value of a dynamical downscaling with the COSMO regional climate model CCLM towards the driving ERA-Interim reanalysis is investigated by comparison with weather station observations. In the mountainous region, the CCLM simulation much better relates to the observed monthly mean 2 m temperature and maximum monthly precipitation sums in summer than ERA-Interim. In addition, the intensity distribution of sub-daily precipitation amounts becomes more realistic with increasing altitude. CCLM does, however, overestimate convection in the mountains and accordingly simulates too much precipitation. Moreover, wintertime near-surface temperature inversions are underrated in the southern near-Gobi area, which leads to too high 2 m temperatures in that region. To examine the ability of the COSMO model to reproduce the vertical thermodynamic structure of the troposphere, additional simulations with the weather forecast version of COSMO were performed for July 2013 and compared to radiosonde measurements of the WATERCOPE field experiment in this region. The results indicate that the COSMO model is quite capable of qualitatively simulating a range of features of the local tropospheric stratification. Mean differences between observed and simulated dew point and temperature profiles were in the range of only to 1-2 °C in the lower troposphere.

    Full Text Available Childhood head and neck cancers are relatively uncommon. Of all head and neck cancers occurring in children, non-Hodgkin′s lymphoma (NHL is the most common, others being rhabdomyosarcoma and nasopharyngeal carcinoma. In the head and neck region, sinuses are the second commonest primary site of NHL after neck lymph nodes. These can be of several different types depending on the predominant cell type and histologic appearance, the most common histological variant being diffuse large B-cell lymphoma. In an attempt to simplify the classification and to develop a universally acceptable classification and staging, they have been classified and staged numerous times over the last three decades, adding more confusion to the topic. Clinical presentations vary according to the histological type. The low grade lymphomas present with a nasal cavity or para-nasal sinus mass associated with obstructive symptoms and/or lymphadenopathy, while high grade lymphomas present with aggressive signs and symptoms including non-healing ulcer, epistaxis, septal perforation and bony destruction. The primary treatment consists of chemotherapy and / or radiation therapy, which is able to achieve remission in two-third of the patients, however, prognosis remains poor with cumulative five-year survival rates at about 30% for all the types of sino-nasal NHLs. Newer targeted therapy (monoclonal antibodies and combination therapies (including stem cells are currently being tested in order to improve survival rates in these patients. This article aims at providing an overview of clinico-epidemiologic characteristics, staging system currently in use, management, prognosis and possibilities of future research in the field of childhood sinonasal NHLs.

  20. A Japan-Sino joint project, ADEC - Aeolian Dust Experiment on Climate Impact

    2004-05-01

    In recent years, aeolian dust has been thought to be an important factor of the climate system on the earth by the radiative forcing effect in the atmosphere and by the influence on the carbon dioxide cycle because deposited dust supplies nutrient salts for the phytoplankton on the ocean surface. Among them, radiative forcing direct and/or indirect effects are important factors of the global warming. Nevertheless, the reliability of the evaluation regarding the radiative forcing impact of aeolian dust is very low. [IPCC, 2001]. This is because the understanding and the model representations of dust entrainment, spatial and temporal distribution of dust, and optical properties of dust particles are not so accurate. Based on this background, Aeolian Dust Experiment on Climate Impact (ADEC) was started in April 2000 as a Japan-Sino Joint Project. The goal of this project is to evaluate the global dust supply to the atmosphere and its radiative forcing direct effect. For this purpose, we have made: 1) in situ observations at desert areas in China for wind erosion processes, 2) network observations from China to Japan, ranging from 80 to 140 East, for understanding spatial-size distribution, chemical, and optical properties of dust particles, and 3) numerical simulation by GCM dust model for evaluation of dust impact on the global climate over the past 50 years. This was planned as a five-year project and two intensive observations, IOP-1, April 12-25 2002, and IOP-2, March 15-26 2003, were put into practice. Intensive observations were made at 6 sites in China (Qira, Aksu, Dunhuang, Shapotou, Beijing, and Qingdao) and 4 sites in Japan (Naha, Fukuoka, Nagoya, and Tsukuba). Preliminary results show that 1) saltation flux at a gobi desert monitored by a newly developed sand particle counter was around 10 times larger than that of a sand dune, which will be caused by the difference of the parent soil size distribution of each ground condition, 2) the background of KOSA

Los argumentos que apoyan esta tesis son fundamentalmente cuatro. El primero, la resistencia de la pedagogía a usar el método científico: si un sistema de enseñanza no funciona, o se niegan los hechos, o se buscan las causas en cir- cunstancias sociales, pero no se cuestiona el sistema. El segundo, la multiplicación de palabras, dando nuevos nombres a cosas que ya tenían uno, para así ocultar la falta de ideas bajo la capa de una jerga supuestamente científica. El tercero, en la utilización de un lenguaje vacío (y se aportarán algunos textos en los que se hacen explícitos algunos mecanismos para vaciar el len- guaje.

Por ello esta investigación busca dar a conocer todos aquellos elementos que son necesarios para lograr una inclusión adecuada de los niños, tomando como centro al niño, reconociéndolo como un ser humano integral que no solo aprende conceptos, sino también aprende a convivir e interactuar con su medio. Es aquí donde debemos tomar en cuenta el respeto a la diversidad que se debe dar en el aula, ya que al convivir se comparten experiencias con personas diferentes, como pueden ser los niños con necesidades especiales o simplemente con las de un niño regular. En esta investigación hemos querido resaltar la importancia de los roles de los agentes educativos para el buen desarrollo de la inclusión de los niños, siendo estos indispensables para lograrlo.

    Dynamic evaluation of sustainable development is one of the key fundamental parts of the success of Sino-Singapore Tianjin Eco-city, which is the first eco-city in China constructed by international cooperation. Based on the analysis of nature and economy, function and structure, planning control indices and so on, we constructed a sustainable development evaluation index system and a system dynamics model of Sino-Singapore Tianjin Eco-city to explore dynamic trends of its population, material and currency by comprehensive utilization of emergy analysis and system dynamics method. Five scenarios were set up and simulated, including inertial scenario, scientific and technological scenario, economic scenario, environmental scenario and harmonious development scenario. Then, the sustainability of the 5 scenarios was evaluated and compared. The results showed that in the economy and environment sustainable development scenario, there was a steady growth trend of GDP, accumulation of both emergy and currency, and relatively lower values in emergy waste ratio, emergy ratio of waste, and emergy loading ratio. Although both sustainable evaluation indices, such as ESI and UEI, were relatively low, the economy and environment sustainable development scenario was still the best development scenario which was more active than others.

    The characteristics of the energy transfer and nonlinear coupling among edge electromagnetic turbulence have been dedicatedly studied in various discharge stages at the sino-united spherical tokamak using multiple Langmuir and magnetic probe arrays. The wavelet bispectral analysis and the modified Kim's method are applied to investigate turbulence properties and their linear growth/damping and nonlinear energy transfer rates, along with multi-field turbulence interactions. The results show diverse features in the linear growth and nonlinear energy transfer between multi-field fluctuations during the current ramp-up, stationary, and internal connection event discharge phases. The diversity implies the importance to develop more sophisticated multi-field models to directly estimate the energy transfer rate among multiple turbulent fields.

  4. Are the streams of the Sinos River basin of good water quality? Aquatic macroinvertebrates may answer the question

    Directory of Open Access Journals (Sweden)

    L. Bieger

    Full Text Available Macroinvertebrate communities are one of the most used groups in assessments of water quality, since they respond directly to the level of contamination of aquatic ecosystems. The main objective of this study was the assessment of the water quality of the Sinos River basin (Rio Grande do Sul state, Brazil through biotic indices based on the macroinvertebrate community ("Family Biotic Index - FBI", and "Biological Monitoring Working Party Score System - BMWP". Three lower order streams (2nd order were selected in each one of three main regions of the basin. In each stream, the samplings were performed in three reaches (upper, middle, and lower, totalling 27 reaches. Two samplings were carried in each reach over one year (winter and summer. A total of 6,847 macroinvertebrates distributed among 54 families were sampled. The streams from the upper region were of better water quality than the lower region. The water quality did not change between the upper, middle and lower reaches of the streams. However, the upper reaches of the streams were of better water quality in all the regions of the basin. The water quality of the streams did not vary between the summer and the winter. This result demonstrated that water quality may be analysed in both studied seasons (summer and winter using biotic indices. The analysis of the results allows us to conclude that the biotic indices used reflected the changes related to the water quality along the longitudinal gradient of the basin. Thus, aquatic macroinvertebrates were important bioindicators of the water and environmental quality of the streams of the Sinos River basin.

    The on-going continent-continent collision between the Indian and Eurasian plates since 55 Ma has created the spectacular topography of the Tibetan plateau. However, many first order questions remain to be answered as to the mechanisms behind this young orogenic process. Under the auspices of the SinoProbe Project, a three dimensional (3-D) Magnetotelluric (MT) array have been deployed on the Tibetan Plateau from 2010 to 2013 to better understand this orogeny. By the end of 2013, 1099 MT stations have been completed, including 102 combined broadband MT (BBMT) and long period MT (LMT) stations. In this study, MT data of these 102 combined stations have been used to investigate the deep lithospheric electrical structure of the Tibetan Plateau. MT impedances within the period range of 10 - 50000 s were extracted to be used for 3-D inversions with the ModEM code using the standard NLCG algorithm. The resulting lithospheric electrical structure of the Tibetan Plateau shows a distinct pattern of strong variation not only vertically, but also horizontally. Conductors are found to be widespread in the middle to lower crust. But their geometries are quite complex, and not obviously consistent with the hypothesis of continuous eastward channel flow. Instead, most crustal conductors in central and southern Tibet display a pattern of N-S extension. In the depth range of the upper mantle, two more conductive regions can be identified in the southern Qiangtang Terrane and in the central Lhasa Terrane. Resistor associated with the underthrust Inidan plate can be traced beneath the Bangong-Nujiang suture in western Tibet, but only beneath the central Lhasa terrane in central Tibet. * This work was jointly supported by the grants from Project SinoProbe-01 and National Natural Science Foundation of China (41404060).

    Full Text Available A comparative analysis between Duque de Rivas’Don Álvaro o la fuerza del sino and La forza del destino by Giuseppe Verdi shows, even in their very titles, the close relationship between Spain and Italy since the days of the Golden Age. Both works posit the old theological problem of compatibility between predestination and free will, while adding new social and political insights into social and racial differences and highlighting the narrowness of the code of honour. Otherwise, as far as the admixture of genres or the treatment of costumbrismo and nationalism are concerned, the difference between both works increases in the second version of Verdi´s opera, in which the alteration of the denouement wipes out the tragical dimension of the spanish play.Un análisis comparativo entre Don Álvaro o la fuerza del sino del duque de Rivas y La forza del destino de Giuseppe Verdi demuestra, ya desde sus títulos, un viaje de y vuelta entre España e Italia que tiene como fondo la literatura del Siglo de Oro. Ambas obras plantean el viejo problema entre providencia y libertad, añadiendo nuevos relieves sociales y políticos sobre las diferencias de clase y raza que ponen en evidencia las estrecheces del código del honor. Las diferencias entre ambas —más allá de la mezcla genérica, el tratamiento costumbrista y el nacionalismo— se acentúan en la segunda versión de la ópera verdiana, que, al cambiar el desenlace, destruyó el sentido trágico del drama español.

The algorithm is based on boundary definitions of the human anatomy along with shape constraints with an automatic initialization of contours to develop a complete algorithm which has a potential to enhance utility at clinical level. Post-initialization; five segmentation techniques: Chan-Vese level set (CVL), localized Chan-Vese level set (LCVL), Bhattacharya distance level set (BDL), Grow Cut (GC), and Sparse Field method (SFM) were used to test the robustness of automatic initialization. Precision and F-score were found to be greater than 80% for all the regions with all five segmentation methods. High precision and low recall were observed with BDL and GC techniques indicating an under segmentation. Low precision and high recall values were observed with CVL and SFM methods indicating an over segmentation. A Larger F-score value was observed with SFM method for all the subregions. Minimum F-score value was observed for naso-ethmoidal and sphenoidal air sinus region, whereas a maximum F-score was observed in maxillary air sinuses region. The contour initialization was more accurate for maxillary air sinuses region in comparison with sphenoidal and naso-ethmoid regions. The overall F-score was found to be greater than 80% for all the airway subregions using five segmentation techniques, indicating accurate contour initialization. Robustness of the algorithm needs to be further tested on severely deformed cases and on cases with different races and ethnicity for it to have global acceptance in Katradental radKatraiology workflow.

    Full Text Available El objetivo de este artículo es analizar el impacto del Mundo del Cobre en la isla de Cuba hasta el inicio de la segunda mitad del siglo XIX. El estímulo británico producido sobre la minería se expresó en la modernización de las instalaciones, la circulación de capitales y la migración de mano de obra. Respecto a este último punto, la migración transoceánica no solo contempló a los británicos que acudieron a la explotación minera de la isla, sino también dio origen a una reactivación del comercio esclavo que tuvo a carabalíes africanos y culíes asiáticos como principales protagonistas. A partir del registro documental de los principales gestores de la modernización minera y la base de datos del comercio transatlántico de esclavos, se relevará la importancia económica y cultural de la circulación de mano obra en Cuba.

  11. Es posible el arte sin estética una aproximación al problema de la estética en el libro ¿Qué es el arte? de Arthur Danto

    2016-01-01

    Full Text Available Este artículo de reflexión se ocupa de analizar la noción de estética en el arte expuesta por Danto en el texto “¿Qué es el arte?”. La hipótesis de lectura es que el arte es posible sin estética si por estética se entiende sólo la exposición de lo bello que da placer visual. Sin embargo, el arte no se puede separar de la estética, si ésta es comprendida como la manera en que las partes de una obra se muestran al mismo tiempo que la justificación para exponerlas de una forma o de otra. Se concluye que la clave para la solución del problema referido a si es posible el arte sin estética, se encuentra en la precisión filosófica, la consistencia y el sentido de pluralidad que Danto le da a la noción de significado encarnado en contraste, pero no en la incompatibilidad con la estética como exposición de lo bello que da placer visual. La estética es indisoluble del arte sí y sólo si lo bello no es el eje central de esta relación, sino algo que hace parte de la expresión artística. Estética no es sinónimo de belleza. Es decir, la belleza puede ser eludible para el arte. Sin embargo, la belleza no puede ser separada de la vida humana porque constituye un valor para los hombres porque es el encuentro positivo entre éstos.

    Background and Aims The flora of the Sino-Japanese plant region of eastern Asia is distinctively rich compared with other floristic regions in the world. However, knowledge of its floristic evolution is fairly limited. The genus Ainsliaea is endemic to and distributed throughout the Sino-Japanese region. Its interspecific phylogenetic relationships have not been resolved. The aim is to provide insight into floristic evolution in eastern Asia on the basis of a molecular phylogenetic analysis of Ainsliaea species. Methods Cladistic analyses of the sequences of two nuclear (ITS, ETS) and one plastid (ndhF) regions were carried out individually and using the combined data from the three markers. Key Results Phylogenetic analyses of three DNA regions confirmed that Ainsliaea is composed of three major clades that correspond to species distributions. Evolution of the three lineages was estimated to have occurred around 1·1 MYA during the early Pleistocene. Conclusions The results suggest that Ainsliaea species evolved allopatrically and that the descendants were isolated in the eastern (between SE China and Japan, through Taiwan and the Ryukyu Islands) and western (Yunnan Province and its surrounding areas, including the Himalayas, the temperate region of Southeast Asia, and Sichuan Province) sides of the Sino-Japanese region. The results suggest that two distinct lineages of Ainsliaea have independently evolved in environmentally heterogeneous regions within the Sino-Japanese region. These regions have maintained rich and original floras due to their diverse climates and topographies. PMID:17981878

    Full Text Available El presente ensayo examina no solo como se forma el miedo moderno y su relación con la tragedia, sino las diversas formas culturales de vivirla respecto al futuro. Se antepone la figura de la personalidad heroica como una construcción moderna centrada en la necesidad de sentir placer por la pérdida. Esta tendencia lleva a las personas a sentirse únicas respecto a otras. Si el héroe es aquel que no se doblega ante el destino, también es un ser que lleva tras sí una historia de dolor y sufrimiento. Ahora bien, tanto los países de raigambre cultural latino como los germánicos han elaborado diferentes formas de vivir lo trágico; lo cierto es que el futuro, como construcción social, juega un rol importante en dichos procesos. Mien- tras para los anglosajones el futuro se mantiene como una entidad inmutable que no puede ser modificada, para los latinos el futuro se construye solo desde el presente. Abstract This essay aims to review how to form not only the modern man’s fear and its relationship with tragedy but also the way to live it according to the future. Heroic per- sonality is chosen as a modern figure focused on the need of pleasure feeling by the loss. This trend makes people to consider themselves unique related to others. If the hero is that one who does not bow down to the fate, it is also a human being who has a pain and suffering story behind him. Now, in those countries of deep seated Latin cultural roots such as German countries have established differ- ent ways of living. One thing is true, the future as social construction plays an important role in those processes. While English speaking countries the future is kept as immutable entity which can not be modified . For Latin people future is built only based on the present.

    The Taihu (Tai lake) region is one of the most economically prospering areas of China. Due to its location within this district of high anthropogenic activities, Taihu represents a drastic example of water pollution with nutrients (nitrogen, phosphate), organic contaminants and heavy metals. High nutrient levels combined with very shallow water create large eutrophication problems, threatening the drinking water supply of the surrounding cities. Within the international research project SIGN (SinoGerman Water Supply Network, www.water-sign.de), funded by the German Federal Ministry of Education and Research (BMBF), a powerful consortium of fifteen German partners is working on the overall aim of assuring good water quality from the source to the tap by taking the whole water cycle into account: The diverse research topics range from future proof strategies for urban catchment, innovative monitoring and early warning approaches for lake and drinking water, control and use of biological degradation processes, efficient water treatment technologies, adapted water distribution up to promoting sector policy by good governance. The implementation in China is warranted, since the leading Chinese research institutes as well as the most important local stakeholders, e.g. water suppliers, are involved.

    To perform the translation, cross-cultural adaptation, and validation of the Sino-Nasal Outcome Test-22 (SNOT-22) questionnaire to the Hebrew language. A single-center prospective cross-sectional study. Seventy-three chronic rhinosinusitis (CRS) patients and 73 patients without sinonasal disease filled the Hebrew version of the SNOT-22 questionnaire. Fifty-one CRS patients underwent endoscopic sinus surgery, out of which 28 filled a postoperative questionnaire. Seventy-three healthy volunteers without sinonasal disease also answered the questionnaire. Internal consistency, test-retest reproducibility, validity, and responsiveness of the questionnaire were evaluated. Questionnaire reliability was excellent, with a high internal consistency (Cronbach's alpha coefficient, 0.91-0.936) and test-retest reproducibility (Spearman's coefficient, 0.962). Mean scores for the preoperative, postoperative, and control groups were 50.44, 29.64, and 13.15, respectively (P < .0001 for CRS vs controls, P < .001 for preoperative vs postoperative), showing validity and responsiveness of the questionnaire. The Hebrew version of SNOT-22 questionnaire is a valid outcome measure for patients with CRS with or without nasal polyps. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    In our recent molecular phylogenetic study of Asian Begonia, two undescribed species, B. guixiensis sp. ined. (S. Guangxi, China) and B. longa sp. ined. (Vietnam), were sampled and placed within the strongly supported clade composed of Begonia sect. Coelocentrum and other co-distributed rhizomatous species in the Sino-Vietnamese limestone karsts. While Begonia sect. Coelocentrum has been recircumscribed based on the phylogenetic relationships, B. guixiensis sp. ined. and B. longa sp. ined. remain illegitimate names. In continuation of our studies in Asian Begonia, these two new species are described and illustrated. Begonia guixiensis resembles B. cylindrica in the peltate, subcoriaceous leaves, differing by the shape of ovary/fruit and the type of placentation. In aspect, B. longa bears a superficial resemblance to B. brevipedunculata in leaf shape in particular, differing by many other features such as the long internodes, shorter petioles and smaller leaves, longer peduncles and 3-locular ovary. The chromosome number of both new species is determined as 2n = 30. A careful study of the literature, herbarium specimens and living plants, both in the wild and in cultivation in the experimental greenhouse, support the recognition of the two new species, which are described and illustrated herein.

  1. Prostrating Walk in the Campaign against Sino-Hong Kong Express Railway: Collective Identity of Native Social Movement

    2017-03-01

    Full Text Available Occupation, blockage and storming are not rare in social movements a decade after China resuming sovereignty in Hong Kong. The organizers and participants usually involve locally born young people. Some of them are secondary school students in their teens. They are known as the fourth generation or post-1980s born Hongkongers. The paper examines the cultural context of social movements involving these youth activists. It mainly studied the campaign against the Sino-Hong Kong Express Railway development project. The project called for the demolition of the Tsoi Yuen Village, a small rural village located on its designed route. Since then, the role of younger generation in social movements has been generally recognized. Social media are widely employed in all stages of the movements with citizen journalists actively involved. The impressive ‘prostrating walk’ imitating Tibetan pilgrims becomes the symbol of these youth activists. It keeps appearing in other campaigns including Occupy Central in Hong Kong in 2014. This paper argues that the rise of nativism, advancement in ICT technology and shifting towards new social movements contribute to the dominant role of youth in recent social movements of Hong Kong. Collective identity of Hongkonger in response to the top-down assimilation by China, strengthens the movement.

    1. The present study was undertaken to examine the responses of the sustained inward current (I(st)) to beta-adrenergic and muscarinic agonists in guinea-pig sino-atrial (SA) node cells using the whole-cell patch-clamp technique. I(st) was detected as the nicardipine (1 microM)-sensitive inward current at potentials between approximately -80 and +20 mV in the presence of low concentration (0.1 mM) of extracellular Ca2+, where the L-type Ca2+ current (I(Ca,L)) was practically abolished. 2. Beta-adrenergic agonist isoprenaline (ISO) in nanomolar concentrations not only increased the amplitude of I(st) but also shifted the membrane potential producing the peak amplitude (Vpeak) to a negative direction by approximately 15 mV without appreciably affecting potential range for the current activation. The stimulatory effect of ISO was concentration-dependent with an EC50 of 2.26 nM and the maximal effect (96.4+/-22.9% increase, n=6) was obtained at 100 nM ISO, when evaluated by the responses at -50 mV. 3. Bath application of acetylcholine (ACh) significantly inhibited I(st), which had been maximally augmented by 100 nM ISO; this inhibitory effect of ACh was concentration-dependent with an IC50 of 133.9 nM. High concentration (1000 nM) of ACh depressed basal I(st) by 10.5+/-2.0% (n=3). 4. In action potential clamp experiments, I(st) was also detected under control conditions and was markedly potentiated by exposure to ISO. 5. These results strongly suggest that I(st) not only contributes to the spontaneous action potentials of mammalian SA node cells but also plays a substantial role in mediating autonomic regulation of SA node pacemaker activity.

  9. Lithospheric structure beneath the northeastern Tibetan Plateau and the western Sino-Korea Craton revealed by Rayleigh wave tomography

    A new 3-D shear wave velocity model of the northeastern (NE) Tibetan Plateau and western Sino-Korea Craton is presented. The model is based on Rayleigh waves recorded at 650 portable stations deployed in the region. Interstation phase and group velocity dispersions for more than 18 000 paths were estimated using the two-station method and then inverted to produce phase velocity maps for 10-80 s period and group velocity maps for 10-60 s period. Local 1-D shear wave velocity profiles for each 0.5° × 0.5°grid node were obtained by inverting Rayleigh wave dispersions obtained in this study together with previously published Rayleigh wave group velocities between 60 and 145 s and then assembled into a 3-D shear wave velocity model. The images obtained reveal an obvious mid-crustal low-velocity zone (LVZ) and low-velocity anomaly in the upper mantle beneath the Songpan-Ganzi terrane. The mid-crustal LVZ can be explained by the presence of partial melting, most likely from asthenospheric upwelling. The existence of a relatively weak mid-crustal LVZ beneath the Qilian orogeny is also confirmed. This LVZ is likely caused by the presence of deep crustal fluids. The Yinchuan-Hetao graben is characterized by relatively low velocities that extend to at least 200 km below the Earth's surface, strongly contrasting with the seismically fast lithosphere of the Ordos and Alax blocks. The model presented here shows the presence of a relatively thick and high-velocity lithosphere beneath the Ordos and NE Alxa blocks, as well as evidence of thinning of the lithosphere beneath the southwestern Alxa and Qilian blocks, indicating that the Alxa block is not subducting beneath NE Tibet.

  10. Carbon fixation in sediments of Sino-Pacific seas-differential contributions of bacterial and archaeal domains

    Oceanic stretches experiencing perpetual darkness and extreme limitation of utilizable organic matter often rely on chemosynthetic carbon (C)-fixation. However, C-fixation is not limited to carbon-deplete environments alone but might also occur in varying degrees in carbon-replete locales depending on the nature and concentration of utilizable carbon, electron donors and acceptors. Quantification of microbial C-fixation and relative contribution of domains bacteria and archaea are therefore crucial. The present experiment estimates the differential rates of C-fixation by archaea and bacteria along with the effects of different electron donors. Four Sino-Pacific marine sediments from Bashi strait (Western Pacific Warm Pool), East China Sea, South China Sea and Okinawa Trough were examined. Total microbial C-uptake was estimated by doping of aqueous NaH14CO3. Total bacterial C-uptake was measured by blocking archaeal metabolism using inhibitor GC7. Archaeal contribution was estimated by subtracting total bacterial from total microbial C-uptake. Effect of electron donor addition was analyzed by spiking with ammonium, sulfide, and reduced metals. Results suggested that C-fixation in marine sediments was not the function of archaea alone, which was in contrast to results from several recent publications. C-fixing bacteria are also equally active. Often in spite of great effort of one domain to fix carbon, the system does not become net C-fixing due to equal and opposite C-releasing activity of the other domain. Thus a C-releasing bacterial or archaeal community can become C-fixing with the change of nature and concentration of electron donors.

  12. Algo sobre la autoestima. Qué es y cómo se expresa

    Full Text Available RESUMEN: La autoestima es uno de los conceptos psicológicos más complejos y uno de los más difíciles de precisar, a pesar de ser un factor que siempre ha estado presente en cualquier intento de explicación del comportamiento humano normal y patológico. Describir adecuadamente qué es la autoestima, requiere abordar previamente algunos aspectos que han influido en la falta de precisión de este concepto. En este sentido es necesario puntualizar que autoconcepto y autoestima no son términos intercambiables aunque ambos se impliquen, que la autoestima no es un factor unitario sino multidimensional, que la autoestima no sólo incluye los aspectos positivos y más valorables del sujeto, sino también aspectos menos valorables o las limitaciones y por último, que la autoestima no es autoafirmación incondicional ante los demás, sino autoafirmación respetando la individualidad de los otros. Se puede definir la autoestima como «la valoración positiva o negativa que el sujeto hace de su autoconcepto, valoración que se acompaña de sentimientos de valía personal y auto aceptación». La autoestima, así entendida, influye y se expresa a través del comportamiento del sujeto en todas sus dimensiones y manifestaciones, tales como autoaceptación, afrontamiento, aceptación de los demás e interacciones sociales, entre otras.ABSTRACT: Self-esteem is one of the most complex psychological concepts an one of the most difficult ones to define, despite the fact that it is a factor that has always been present in any attempt to explain the normal and pathological human behavior. In order to describe adequately what self-esteem is we need to first look at some of the aspects that have contributed to the lack of precision of this concept. We need to make clear that self-concept and self-esteem are not interchangeable terms even though they are both in some way related, that self-esteem not a unitary factor but multidimensional, that self-esteem not

    Enormous mountainous forests in Sino-Himalayans and Siberia harbor important avian biodiversity in the Northern Hemisphere. Numerous studies in last two decades have been contributed to systematics and taxonomy of passerines birds in these regions and have revealed various and complex phylogeographic patterns. A passerine species Red-flanked Bluetail Tarsiger cyanurus provided a good system to manifest such evolutionary complexity. The subspecies T. c. cyanurus and T. c. rufilatus (or/and T. c. pallidior), divergent in morphology, acoustics, and migratory strategies are allopatric in Siberia and Sino-Himalayan forests, respectively. The two taxa most likely deserve full species status but rigorous genetic analysis is missing. In this study, multilocus phylogeography based on mitochondrial DNA and Z-linked DNA reveals that T. c. cyanurus and T. c. rufilatus are reciprocally monophyletic with significant statistical support and differ with a large number of diagnostic nucleotide sites resulting substantial genetic divergence. Our finding supports the proposed split of Tarsiger cyanurus s.l. that T. cyanurus and T. rufilatus should be treated as two full species. Whether “pallidior” is a subspecies or geographical form of T. rufilatus is still uncertain. Additionally, these two forest passerine species may have diverged 1.88 (3.25–1.30) Mya, which might be shaped by geographical vicariance due to grassland and desert steppe on the central Loess Plateau during the Pliocene. Taken together, this study and further suggests another independent example of North Palearctic–Sino-Himalayan phylogeographic pattern in Palearctic birds. PMID:24772276

No sólo hablamos de un replanteamiento y adaptación a las nuevas tecnologías, sino una “nueva forma” de pensar las marcas y su repercusión e imagen en la mente de los consumidores. Tal es el caso de las aplicaciones para los smartphones, que se han desarrollado con una virulencia impresionante, aproximadamente 200.000 actualmente, y el número continúa creciendo. Este estudio pretende ser una primera aproximación a la aparición de las marcas en las aplicaciones para móviles, específicamente en las aplicaciones destinadas a iPhone.Gracias esta investigación sabemos que es indispensable tener en cuenta tres criterios básicos en el desarrollo de aplicaciones; el primero y más importante es que los anunciantes deben centrarse en el análisis de las necesidades de los usuarios, determinar sus objetivos, elaborar planes de integración y sobre todo preparar los medios de comunicación multicanal y de apoyo a la comercialización. Si la aplicación es correcta pero no funciona adecuadamente, deteriora la imagen de la marca de cara al cliente. En segundo lugar, la experiencia del usuario en las aplicaciones móviles debe ser complementaria y coherente con su experiencia a través de otros canales, es decir, debe mantenerse fiel a la marca y a la identidad de la empresa. Y el tercer criterio, es importante para la marca ir adaptándose a las nuevas tecnologías, pues una incorporación precaria y mal desarrollada puede ser más perjudicial que no el

    The picturesque limestone karsts across the Sino-Vietnamese border are renowned biodiversity hotspot, distinguished for extremely high endemism of calciphilous plants restricted to caves and cave-like microhabitats that have functioned as biological refugia on the otherwise harsh habitats. To understand evolutionary mechanisms underlying the splendid limestone flora, dated phylogeny is reconstructed for Asian Begonia, a species-rich genus on limestone substrates represented by no less than 60 species in southern China, using DNA sequences of nrITS and chloroplast rpL16 intron. The sampling includes 94 Begonia species encompassing most major Asian clades with a special emphasized on Chinese species. Except for two tuberous deciduous species and a species with upright stems, a majority of Sino-Vietnamese limestone Begonia (SVLB), including sect. Coelocentrum (19 species sampled) and five species of sect. Diploclinium, Leprosae, and Petermannia, are rhizomatous and grouped in a strongly supported and yet internally poorly resolved clade (Clade SVLB), suggesting a single evolutionary origin of the adaptation to limestone substrates by rhizomatous species, subsequent species radiation, and a strong tendency to retain their ancestral niche. Divergence-time estimates indicate a late Miocene diversification of Clade SVLB, coinciding with the onset of the East Asian monsoon and the period of extensive karstification in the area. Based on our phylogenetic study, Begonia sect. Coelocentrum is recircumscribed and expanded to include other members of the Clade SVLB (sect. Diploclinium: B. cavaleriei, B. pulvinifera, and B. wangii; sect. Leprosae: B. cylindrica and B. leprosa; sect. Petermannia: B. sinofloribunda). Because species of Clade SVLB have strong niche conservatism to retain in their ancestral habitats in cave-like microhabitats and Begonia are generally poor dispersers prone to diversify allopatrically, we propose that extensive and continuous karstification of the

    The Earth System Documentation (ES-DOC) project is an international effort aiming to deliver a robust earth system model inter-comparison project documentation infrastructure. Such infrastructure both simplifies & standardizes the process of documenting (in detail) projects, experiments, models, forcings & simulations. In support of CMIP6, ES-DOC has upgraded its eco-system of tools, web-services & web-sites. The upgrade consolidates the existing infrastructure (built for CMIP5) and extends it with the introduction of new capabilities. The strategic focus of the upgrade is improvements in the documentation experience and broadening the range of scientific use-cases that the archived documentation may help deliver. Whether it is highlighting dataset errors, exploring experimental protocols, comparing forcings across ensemble runs, understanding sub-mip objectives, reviewing citations, exploring component properties of configured models, visualizing inter-model relationships, scientists involved in CMIP6 will find the ES-DOC infrastructure helpful. During this PICO session scientists will be walked through demonstrations of various aspcects of the ES-DOC eco-system. Documentation will be created & published, viewed and compared. Following the walk-throughs scientitists will realize that documenting their work has been greatly simplified and provides concrete benefits.

    1999-08-01

    This occasional paper identifies applicable cooperative monitoring techniques and develops models for possible application in the context of the border between China and India. The 1993 and 1996 Sino-Indian agreements on maintaining peace and tranquility along the Line of Actual Control (LAC) and establishing certain confidence building measures (CBMs), including force reductions and limitation on military exercises along their common border, are used to examine the application of technically based cooperative monitoring in both strengthening the existing terms of the agreements and also enhancing trust. The paper also aims to further the understanding of how and under what conditions technology-based tools can assist in implementing existing agreements on arms control and confidence building. The authors explore how cooperative monitoring techniques can facilitate effective implementation of arms control agreements and CBMS between states and contribute to greater security and stability in bilateral, regional, and global contexts.

    The Sinos River is one of the most polluted rivers in Brazil. The purpose of this work was to monitor the presence of some pesticides and hydrocarbons as well as the genotoxic and cytotoxic potential on HEp-2 cells from water samples collected at seven sites in the Sinos River Basin (SRB), southern Brazil. Nine samples were taken from the three main rivers in the SRB and used as a solution to dilute the HEp-2 cell culture medium after microfiltration. Twenty-four pesticides and 19 hydrocarbons were measured. Cytotoxicity was assessed by methyl thiazolyl tetrazolium (MTT) and neutral red (NR) assays, in which cells were exposed to different concentrations of the water samples for 24 h. Genotoxicity of the microfiltrated raw water samples was assessed by comet assay after 6 and 24 h of exposure. Among the chemicals analyzed, only the 2,4-D, dichloromethane, tetrachloroethene, chloroform, bromodichloromethane, styrene, and toluene were detected, but they were all lower than the limit established by Brazilian regulations. Twenty samples from a total of 60 had a cytotoxic effect in the MTT assay and 30 in the NR assay. The comet assay indicated the presence of genotoxic substances in the water at the seven locations monitored. Temporal and spatial variation was observed in the cytotoxicity and genotoxicity assays. Results indicated that the water in all stretches of the SRB is contaminated and it can cause harmful effects to humans and to the aquatic biota. This HEp-2 cell-line approach can be an additional tool for environmental monitoring.

    Full Text Available Abstract The present study evaluated the genotoxic effects of the atmospheric air on Tradescantia pallida var. purpurea in urban areas with different intensities of vehicular traffic and in riparian forest fragments in the Sinos River Basin (Rio Grande do Sul, Brazil, considering the influence of climatic conditions prevailing in these environments. Bimonthly, from May 2012 to March 2013, cuttings with flower buds were exposed for 8 h in urban and riparian forest environments in the municipalities of Caraá, Taquara and Campo Bom in the upper, middle and lower sections, respectively, of the Sinos River Basin. Simultaneously, negative controls were made and climatic data were recorded. Micronuclei (MCN frequencies were determined in young tetrads of pollen mother cells and expressed as MCN/100 tetrads. Significantly higher MCN frequencies were observed in buds exposed in urban and riparian forest environments in Taquara (up to 7.23 and 4.80, respectively and Campo Bom (up to 4.90 and 4.23, respectively than in buds exposed in Caraá (up to 2.90 and 2.50, respectively, in the majority of samplings, and in relation to the negative control (up to 1.93 in all months. Over the course of the period monitored, there were significant variations in MCN frequencies at all sampling points, with the exception of the urban environment in Caraá. For the urban environments, relation between the MCN frequency, vehicular traffic and mean temperature was observed. For the riparian forest fragments, there was no association between MCN frequency and climatic factors. Tradescantia pallida var. purpurea can be considered a useful tool to point out areas with increased atmospheric pollution, since the exposure of plants under severe climatic conditions is avoided to minimize their negative influence on the formation of micronuclei.

    Full Text Available La represión de la oferta de drogas ilícitas es anlizada en un contexto de equilibrio general. Los riesgos de la actividad productora de drogas son explícitamente considerados y las drogas son pensadas como bienes básicos. El modelo estático arroja que la represión de la oferta de drogas amplifica la ofera incrementando su rentabilidad. Adicionalmente, en un contexto de economía abierta la mayor demanda del mercado mundial induce una mayor especialización del país productor de drotas. Finalmente, una versión dinámica del modelo arroja que la represión de la oferta de drogas disminuye la tasa de crecimiento económico tanto en el corto como en el largo plazo. Por consiguiente, estos modelos predicen que la represión de la oferta de drogas ilícitas no es sólo inútil sino también contraproducente.

  1. The Epigenetic Paradox of Pluripotent ES Cells.

    Science.gov (United States)

    Festuccia, Nicola; Gonzalez, Inma; Navarro, Pablo

    2017-05-19

    The propagation and maintenance of gene expression programs are at the foundation of the preservation of cell identity. A large and complex set of epigenetic mechanisms enables the long-term stability and inheritance of transcription states. A key property of authentic epigenetic regulation is being independent from the instructive signals used for its establishment. This makes epigenetic regulation, particularly epigenetic silencing, extremely robust and powerful to lock regulatory states and stabilise cell identity. In line with this, the establishment of epigenetic silencing during development restricts cell potency and maintains the cell fate choices made by transcription factors (TFs). However, how more immature cells that have not yet established their definitive fate maintain their transitory identity without compromising their responsiveness to signalling cues remains unclear. A paradigmatic example is provided by pluripotent embryonic stem (ES) cells derived from a transient population of cells of the blastocyst. Here, we argue that ES cells represent an interesting "epigenetic paradox": even though they are captured in a self-renewing state characterised by extremely efficient maintenance of their identity, which is a typical manifestation of robust epigenetic regulation, they seem not to heavily rely on classical epigenetic mechanisms. Indeed, self-renewal strictly depends on the TFs that previously instructed their undifferentiated identity and relies on a particular signalling-dependent chromatin state where repressive chromatin marks play minor roles. Although this "epigenetic paradox" may underlie their exquisite responsiveness to developmental cues, it suggests that alternative mechanisms to faithfully propagate gene regulatory states might be prevalent in ES cells.

    The aim of this study was to analyze the associations between occupational stress, burnout and turnover intention and explore their associated factors among managerial staff in Guangzhou, China. This cross-sectional study recruited 288 managerial employees from a Sino-Japanese joint venture automobile manufacturing enterprise in Guangzhou. The questionnaire included questions about sociodemographic characteristics, smoking, drinking and physical activity and the Chinese versio ns of the Occupational Stress Indicator (OSI), Maslach Burnout Inventory (MBI), Eysenck Personality Questionnaire (EPQ), Simplified Coping Style Questionnaire (SCSQ) and Social Support Rating Scale (SSRS). The response rate was 57.6%. Stepwise regression analysis was performed to examine the associations between burnout and occupational stress and turnover intention and related factors. The respondents had a high level burnout on the personal accomplishment subscale and had a high prevalence of turnover intention. Neuroticism, psychoticism, job satisfaction, occupational stress and social support were strong predictors of emotional exhaustion. Psychoticism, passive coping, occupational stress, objective support, utilization of support, male gender and job satisfaction were strong predictors of depersonalization. Active and passive coping and job satisfaction were strong predictors of personal accomplishment. Job dissatisfaction and emotional exhaustion were strong predictors of turnover intention. High occupational stress and low job satisfaction were associated with high burnout, particularly in the emotional exhaustion and depersonalization dimensions. Low job satisfaction and high emotional exhaustion were associated with high turnover intention among employees. Personality traits, social support and coping style were also found to be associated with burnout.

    To assess and compare the predictive ability of three risk evaluation systems (SinoSCORE, EuroSCORE II and the STS risk evaluation system) in patients aged ≥70, and who underwent coronary artery bypass grafting (CABG) in East China. Three risk evaluation systems were applied to 1,946 consecutive patients who underwent isolated CABG from January 2004 to September 2016 in two hospitals. Patients were divided into two subsets according to their age: elderly group (age ≥70) with a younger group (age evaluation system were 0.78(0.64)%, 1.43(1.14)% and 0.78(0.77)%, respectively. SinoSCORE achieved the best discrimination (the area under the receiver operating characteristic curve (AUC) = 0.829), followed by the STS risk evaluation system (AUC = 0.790) and EuroSCORE II (AUC = 0.769) in the entire cohort. In the elderly group, the observed mortality rate was 4.82% while it was 1.38% in the younger group. SinoSCORE (AUC = .829) also achieved the best discrimination in the elderly group, followed by the STS risk evaluation system (AUC = .730) and EuroSCORE II (AUC = 0.640) while all three risk evaluation systems all had good performances in the younger group. SinoSCORE, EuroSCORE II and the STS risk evaluation system all achieved positive calibrations in the entire cohort and subsets. The performance of the three risk evaluation systems was not ideal in the entire cohort. In the elderly group, SinoSCORE appeared to achieve better predictive efficiency than EuroSCORE II and the STS risk evaluation system.

    In XVIIIth century on Encyclopaedists influence, the study of Sciences arouse a real passion. Many courses are proposed. Two private institutions are opened which are called "Lycées": "Lycée de la rue de Valois" and "Lycée des Arts". Fourcroy and Lavoisier have been influential members of these two. Problems come to "Lycée de la rue de Valois", lead to the "purge ballot" and to Lavoisier's eviction. In France, it is the "Terror" and Lavoisier few months after was guillotined as "Fermier general". The historic events exonerate Fourcroy, member of the Convention, to the accusation that he has no made steps to save Lavoisier. This important historic event is a part of this study. As we show in this study "Lycées" are been small universities and have contributed to maintenance bonds between French scientists at the Revolution. The "Musée de Paris" and the "Société Philomathique de Paris" are also evoked.

    Full Text Available The sense or meaning of a word resides in thought and only manifests itself when the word is used. Yet the sense conveyed can be equivocal if the word is taken out of its context, spatial as well as temporal. Considering the present time then, we are dealing with the determination of a space, with exploring around the contextual area. The study that resulted in this paper involves geography, but is no geographical research; at most research on human geography. Although it involves speech, its direct object is not language. Neither it is, in strictness, ethnography nor cultural anthropology. But it concerns all of these fields and, therefore, cannot stay away from any of them. Only one concept, perhaps, overrides the whole undertaking and meets the double condition of being simple and complex at the same time: the concept of elementary area. This concept rests upon the seminal idea of taking the sense and meaning of something (in this case, a name or a noun as the use given to such something (such name or noun in a particular space: a here and a now. One word or signifier, one single meaning; that is all there is. Yet it is this extreme simplification that which allows freedom of speculation, clear and refined.

Pero la información que conlleva la misma es equívoca si hacemos abstracción de un lugar y de un tiempo. Sea el tiempo actual.

Concierne al habla, pero su objeto directo no es la lengua. No es tampoco, en sentido estricto, etnografía ni antropología cultural. Pero siendo un poco todo ello, no puede prescindir de nada. Sólo uno de sus conceptos, quizá, presida todo el conjunto y reúna la doble condición de ser complejo y a la vez simple:

    PHOEBE (PHysics Of Eclipsing BinariEs) is a modeling package for eclipsing binary stars, built on top of the widely used WD program (Wilson & Devinney 1971). This introductory paper overviews most important scientific extensions (incorporating observational spectra of eclipsing binaries into the solution-seeking process, extracting individual temperatures from observed color indices, main-sequence constraining and proper treatment of the reddening), numerical innovations (suggested improvements to WD's Differential Corrections method, the new Nelder & Mead's downhill Simplex method) and technical aspects (back-end scripter structure, graphical user interface). While PHOEBE retains 100% WD compatibility, its add-ons are a powerful way to enhance WD by encompassing even more physics and solution reliability.

    Full Text Available Climate change is a threat to the attainment of the Sustainable Development Goals (SDGs in sub-Saharan Africa as its impacts can lead to increased incidences of poverty and inequality which can subsequently lead to a 12% decline in the Human Development Index (HDI for sub-Saharan Africa. Emerging countries such as China have the potential to support Africa to achieve the SDGs by pioneering South–South Climate Finance (SSCF modalities. In order to increase knowledge on climate informed development and the role of China in global climate governance, the paper examined various research articles, case studies, policy briefs and project reports. Sino-African aid, investments and trade were noted as essential in mitigating Africa's climate change vulnerabilities which induce poverty traps and inequality. Some African countries were noted to have a comparative advantage in environmental standards over China but lacked the initiative to use this comparative advantage to enhance the Forum on China–Africa Cooperation (FOCAC and assist China to have a sustainable growth trajectory. The paper concludes that SSCF modalities can enhance climate risk management in Africa if they focus on improving financial inclusion and improving climate finance flows towards climate change adaptation activities in Africa. Additionally, to increase the effectiveness and impact of Chinese climate finance support to Africa, African policymakers should not allow political and market forces to decide how climate related support from China should be allocated as decisions based on political and market forces could potentially promote an inequitable distribution of funds and ignore the most vulnerable countries and regions.

    This research aimed to evaluate the air quality, by determining the concentrations of PM2.5-10, PM2.5 and the metallic elements Al, Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn and Hg in the leaf part of ryegrass (Lolium multiflorum) in an area close to Schmidt Stream, at the lower section of Sinos River Basin (SRB), in a research campaign of six months, from October 2013 to March 2014. The particles collected in the PM sampling were analyzed by Scanning Electron Microscopy (SEM) combined with Energy Dispersive X-ray Spectrometry (EDS), in order to study their morphology and chemical composition. The mean concentration of PM2.5-10 was 9.1 µg m(-3), with a range of 2.2 µg m(-3) to 15.4 µg m(-3) and the mean concentration of PM2.5 was 4.7 µg m(-3), with a range of 1.9 µg m(-3) to 8.2 µg m(-3). Concentrations of metallic elements, especially Pb, Cr and Zn, were classified as Class 4 (very high pollution levels), according to the classification proposed by Klumpp et al. (2004). Chemical and morphological analysis of PM revealed the presence of particles of biological origin, soot (Cr, Fe, Ni, Zn, Cd, Hg and Pb), salts (KCl) and soil resuspension (Al and Si). The integrated study methodology, employing environmental variables, such as PM and ryegrass, can be of help in the preparation of wide-ranging environmental diagnoses, in addition providing information needed to develop precautionary measures designed to minimize the effects of atmospheric pollution that takes into consideration the environment's supportive capacity and environmental quality.

Siguiendo las ideas del matemático y físico teórico Freeman Dyson2, quien afirma que no puede haber visión científica única cono no puede haber una visión poética única, quisiera recordar que la ciencia se puede entender como el resultado de una serie de visiones conflictivas y parciales, donde lo común de ésta se encontraría en la rebelión de las restricciones impuestas por cualquier cultura prevaleciente.Asumir un conocimiento como verdad definitiva sólo sirve para estrechar el pensamiento, “aquellos a quienes ni siquiera se les ocurre que es posible estar equivocado no pueden aprender otra cosa que habilidades practicas” (Bateson, p23. Lo importante de una medición entonces, radica en observar el entorno guiado de manera fundamental por las diferencias, las cuales deberán desde ahora ser un bien atesorable, mas que algo donde la psicología puede contribuir a normalizar. De este modo, si la psicología aspira a ser considerada una ciencia, debería serlo en su completo y real campo semántico y no sólo buscando autoridad o validación social. Por otro lado, no debería renegar la noción de “arte” en la praxis psicológica, pues el término no refiere sólo a la creación artística, sino que además designa el saber técnico encaminado a un fin practico - individual (trabajo del artesano.

    Full Text Available El dolor es una experiencia cognitiva como resultado de la activación de nociceptores o descritas en esos términos. El estímulo nociceptivo desencadena la activación de redes neuronales que procesan la información en forma paralela y distribuida, con un componente discriminativo en el tálamo y corteza primaria contra lateral y otro afectivo en la corteza del cíngulo anterior y prefrontal dorsolateral. El dolor como experiencia psíquica solo puede ser objetivado en sus aspectos de activación de las áreas de la así llamada matriz de dolor, mediante la técnica de resonancia magnética funcional. Con el registro de la actividad de nociceptores en sujetos despiertos y en pacientes con dolor neuropático mediante microneurografía se puede relacionar la actividad anormal en estos receptores con la sensación evocada.

    Full Text Available O linfossarcoma é uma neoplasia linfóide que se origina em órgão sólido e que, em cães, não tem ainda uma etiologia determinada. O diagnóstico dessa neoplasia pode ser feito tanto por citologia como por histopatologia, embora, muitas vezes, sua diferenciação de leucemia linfóide seja difícil. Vários sinais clínicos são associados com o linfossarcoma canino, a maioria deles relacionada ao órgão na qual o tumor se localiza. Uma manifestação comum é a linfadenopatia generalizada que deve ser diferenciada de outras enfermidades que causam aumento de volume dos linfonodos. Algumas síndromes paraneoplásicas complicam casos de linfossarcoma e, muitas vezes, são responsáveis pela morte do animal. Neste trabalho, são revisados os aspectos clínicos, laboratoriais, as alterações de necropsia e histopatologia do linfossarcoma canino.

    Full Text Available Introducción: Cualquier practicante de ciencia está frecuentemente expuesto al discurso público (DP: conferencias, congresos, simposios, seminarios, entrevistas, talleres, etc. Por ello, es imprescindible saber comunicar las ideas con claridad y contundencia en una presentación oral. Usualmente, profesionistas y estudiantes enfrentan estas situaciones utilizando el sentido común, asumiendo que las habilidades para dar una buena presentación oral se adquieren con la práctica. Sin embargo es común ver profesionistas que a pesar de tener años de experiencia en foros de DP, siguen haciendo presentaciones orales muy deficientes. La hipótesis de este trabajo es que la práctica, por sí misma, puede no ser la única forma de adquirir dichas habilidades, sino que es posible mejorar el desempeño en las presentaciones orales mediante la enseñanza de las bases científicas del DP. Método: Tras una presentación oral individual de 10 minutos, se aplicó una prueba de desempeño en el DP (prueba Rapee a un grupo de 15 alumnos de posgrado en ciencias marinas antes y después de tomar un curso de DP. En el curso se enseñó la ciencia que existe detrás del DP, los protocolos del DP en la ciencia y la aplicación de los principios del diseño gráfico en el material de apoyo visual de una presentación oral.

    2016-01-01

    This paper explores advanced electrode modeling in the context of separate and parallel transcranial electrical stimulation (tES) and electroencephalography (EEG) measurements. We focus on boundary condition based approaches that do not necessitate adding auxiliary elements, e.g. sponges, to the computational domain. In particular, we investigate the complete electrode model (CEM) which incorporates a detailed description of the skin-electrode interface including its contact surface, impedance and normal current distribution. The CEM can be applied for both tES and EEG electrodes which is advantageous when a parallel system is used. In comparison to the CEM, we test two important reduced approaches: the gap model (GAP) and the point electrode model (PEM). We aim to find out the differences of these approaches for a realistic numerical setting based on the stimulation of the auditory cortex. The results obtained suggest, among other things, that GAP and GAP/PEM are sufficiently accurate for the practical appli...

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available China faces a number of impressive challenges in dealing with climate change: rising energy use, growing emission levels of greenhouse gases, dangerous levels of air pollution over cities and low resilience against flood and drought. Sustainable urbanization has been adopted as a keyword in handling these challenges. The Chinese central government has undertaken a variety of measures, including the launch of large Sino-European programs to learn from ‘developed nations’. In the wake of these partnerships, a great variety of cross-national and cross-city agreements were signed. Sino-European cooperation does not often run as smoothly as initially hoped because of diverging interests, cultural misunderstandings and practical limitations. In the background, a mismatch in normative conceptions Chinese and European participants have of ‘good governance’ plays a role. In this contribution, insights taken from Montesquieu’s ‘The Spirit of Laws’ regarding checks and balances and trias politica (updated to ‘sextas politica’ for the 21st century are used to comprehend how the exertion of power is distributed and expected to be distributed differently in Chinese than in European administrative traditions. The article will end with conclusions on how European misconceptions of Chinese governance complicate Sino-European collaboration in sustainable urbanization policies.

    Full Text Available Marisol Calambás Soscué presenta su recorrido creativo como una búsqueda de nuevas técnicas y formas plásticas para expresar la memoria ancestral del pueblo Nasa al que pertenece. Es necesario escapar del estancamiento artificial impuesto por el mercado turístico que etiqueta las obras indígenas como ‘artesanías’ y exige la repetición de patrones supuestamente ancestrales. La creatividad de los artistas contemporáneos indígenas, muestra Marisol, fluye transformando constantemente los canales de comunicación de la memoria. Es necesario, por tanto, educar la mirada del público para que aprenda a ver dichas transformaciones. 

  10. Aprender a trabajar en equipo es desarrollar más de una competencia

    Full Text Available La cooperación entre el profesorado no suele ser habitual, y cuando se lleva a cabo es en periodos de tiempo breves y asociados a tareas de ámbito institucional. Se plantea la cooperación como una realidad que depende de la situación en la que se ejerce el trabajo cooperativo, quedando determinado su ejercicio por el hecho de aprender a cooperar en la formación inicial, a fin de perder el miedo a la falta de habilidad para su ejercicio, aunque ello no garantiza una cooperación efectiva sino que, además, es necesario el entrenamiento. Aprender haciendo constituye uno de los recursos vitales para su desar rollo, ya que proporciona la posibilidad d e ejercitar lo conceptualizado. Se abordan tres grandes núcleos en el artículo, a saber: competencias de las que depende el funcionamiento o la desaparición de un equipo de trabajo; competencias sobre las que se co nstituye la base del funcionamiento del equipo pedagógico y las “herramientas” de enseñanza de las que se dispone para desarrollar estas habilidades. Respecto a este tercer aspecto, se aborda la necesidad de analizar las tareas a desarrollar para ejercita r las competencias que favorecen el trabajo en equipo: Espaciar la formación en fases para aprender a trabajar en equipo, evitando procesos formativos intensivos, que resultan ser estériles; definir las pautas de trabajo en función de las tarea ideadas; ej ercitar la reflexión sobre la naturaleza y orientación del trabajo a desarrollar y analizar desde distintas perspectivas qué sucede cuando se trabaja en equipo - acciones cognitivas - , valorando en cada momento sobre qué se debate y qué está en juego o asumi endo cada miembro del equipo, en cada momento , el papel previamente asignado.

    Full Text Available El termino calidad de vida es usualmente empleado de manera vaga y sin ninguna definición clara. En México la calidad de vida se a estudiado en pacientes enfermos, por eso nuestra inquietud de investigar sobre esta en estudiantes que no presentan ninguna enfermedad , limitación física, económica, social o mental Se encuestaron a 500 estudiantes universitarios de  la Universidad Autónoma de Puebla, Universidad de las Américas, Instituto Culinario de Puebla y U. De Guadalajara, a los cuales se les aplico uno de los diferentes 9 cuestionariosautoaplicables basados en estructura de escala global y a los parámetros clinimétricos de pregunta directa. El objetivo fue determinar lo que los estudiantes incluyen en calidad de vida  dependiendo en la calificación que otorguen a esta. Nos damos cuenta que para los estudiantes que considera que su calidad de vida muy agradable, se basan en que estén bien socioeconomicamente y estabilidad familiar; los que calificaron de totalmente agradable o agradable refieren tener todo sin especificar, buena los que ya mencionan aspectos negativos de su vida ,mientras para los que la calificaron como muy desagradable fue por falta de  éxito y superación personal, Sin mencionar el ambiente familiar, nadie califico su calidad de vida como totalmente desagradable. Para la mayoría de los profesionales  en la salud la calidad de vida se basa en el estado de salud del paciente (físico o mental sin tomar en cuenta aspectos tan importantes como son estabilidad familiar, económica, social y cultural En base a los resultados obtenidos se observo que para la mayoría de los estudiantes su calidad de vida no se basa en el estado de salud, sino en sus relaciones familiares, nivel socioeconómico y realización personal. Por lo que es necesario que en México se investigue mas sobre lo parámetros que se toman en cuanta para calificar la calidad de vida del paciente.

En otras palabras, la pobreza, la falta de oportunidades educativas y laborales, la carencia de servicios y de derechos sociales, etc., están repartidas no sólo con base en la condición social en que se encuentran los individuos, sino que se acentúan con la pertenencia o no pertenencia a un determinado grupo étnico. En este sentido, el propósito del artículo es exponer diversos indicadores sociodemográficos de la población otomí del Estado de México, para demostrar las condiciones de desventaja frente a la población no indígena a pesar de pertenecer a los mismos municipios y etnorregión.

    Trish, Erin; Dimos, John; Eggan, Kevin

    2006-11-09

    Here we demonstrate how our lab begins a HuES human embryonic stem cell line culture from a frozen stock. First, a one to two day old ten cm plate of approximately one (to two) million irradiated mouse embryonic fibroblast feeder cells is rinsed with HuES media to remove residual serum and cell debris, and then HuES media added and left to equilibrate in the cell culture incubator. A frozen vial of cells from long term liquid nitrogen storage or a -80 C freezer is sourced and quickly submerged in a 37 C water bath for quick thawing. Cells in freezing media are then removed from the vial and placed in a large volume of HuES media. The large volume of HuES media facilitates removal of excess serum and DMSO, which can cause HuES human embryonic stem cells to differentiate. Cells are gently spun out of suspension, and then re-suspended in a small volume of fresh HuES media that is then used to seed the MEF plate. It is considered important to seed the MEF plate by gently adding the HuES cells in a drop wise fashion to evenly disperse them throughout the plate. The newly established HuES culture plate is returned to the incubator for 48 hrs before media is replaced, then is fed every 24 hours thereafter.

    2012-01-01

    Full Text Available El análisis de la metrópoli de Barcelona nos ayuda a tomar el tema de la financiarización de la producción del espacio que ha venido ocurriendo en los últimos años en varios países, incluso en Brasil. Este proceso se presenta en el mundo con distintos ritmos e intensidades, ya que cuenta con diferentes mediaciones históricas, políticas, institucionales, económicas, ideológicas y sociales entre los países de economías avanzadas y aquellos llamados en desarrollo. En este sentido, es importante considerar el modo como ocurre este proceso en un país como España, que sustentó su gran crecimiento económico de la última década en las bases de la producción inmobiliaria del espacio bajo un capitalismo financiarizado. Es posible identificar en este país las contradicciones acerca de la realización de los negocias inmobiliarios - lo incremento del valor del suelo urbano y los conflictos planteados por la apropiación del espacio urbano para la vida de la gente, lo que revela la lucha contra la expropiación financiera y inmobiliaria de los hogares más pobres o sobreendeudados. Este camino nos puede ayudar en la interpretación de la producción globalizada del espacio, en el caso aquí planteada a través de la expansión metropolitana y periférica de la producción de la vivienda en Barcelona, lo que nos pone frente a una crisis no sólo económica sino más bien una gran crisis social.

    Full Text Available Por su poder diferenciador, y su débil contingencia a la moda el turismo cultural se ha convertido en un reto para los destinos. No solo dinamiza zonas de interior sino que es una manera para algunos destinos de salvar su patrimonio y crear empleos. Sin embargo, el concepto de turismo cultural es complejo y su delimitación y medición difíciles. En una primera parte teórica, este trabajo realiza una revisión conceptual del turismo cultural enfocando la dialéctica existente entre experiencia y autenticidad, y destacando después la diversidad de tipologías de turismo y de turista cultural. En la parte empírica, después de abordar la dificultad de medición, se presenta un estudio con series temporales de datos seleccionados de fuentes públicas analizadas mediante regresiones lineales con el objetivo de estudiar el efecto del turismo cultural sobre el gasto en turismo en España.

    Full Text Available Las cámaras de videovigilancia llevan años proliferando en casi todo el mundo. Sin embargo, ni las evaluaciones existentes dan motivos que justifiquen este entusiasmo por las cámaras en la lucha contra la delincuencia, ni las imágenes grabadas han servido de forma determinante en la prevención o resolución de grandes delitos recientes. La pregunta que emerge, pues, es: ¿cómo es posible que la videovigilancia haya conseguido no solo imponerse sino seguir una trayectoria de expansión, mantener cifras de apoyo popular considerables y generar un consenso favorable inquebrantable entre los responsables políticos, las autoridades policiales y la población en general? A través del repaso a las propuestas académicas realizadas hasta ahora que vinculan la videovigilancia con procesos económicos, sociológicos y políticos más amplios, y con base en los trabajos existentes sobre la evolución de la proliferación de la videovigilancia en España, este artículo pone sobre la mesa, desde una perspectiva sociológica y politológica, la pregunta que nadie parece tener deseos de plantear: ¿por qué la videovigilancia?

El enfoque metodológico es cualitativo, de tipo descriptivo y explorato- rio. Participaron 18 enfermeros que actúan en el prenatal de la ESF, en Natal / RN. Los datos fueron recolectados en julio del 2008, mediante un plan de entrevista semi-estructurada. Fue usada la técnica de análisis de contenido, en la modalidad de análisis temático. Como resultados, informes describen las dificultades referidas al trabajo del enfermero en el prenatal para prevenir la DPP, no en relación a la propia ESF, sino a la forma en que se llevan a cabo las consultas prenatales, dificultando un planteo integral de la gestante. Se concluye que las intervenciones de Enfermería realizadas durante el prenatal pueden promover el bienestar general de la mujer, del niño que va a nacer y de la familia, contribuyendo en la prevención de la DPP.

    2011-12-01

    Full Text Available The article seeks to explore three strands of Peruvian republicanism between 1821 and 1834. One of these was the «patria científica» [scientific homeland] which flourished within the heart of the Sociedad Patriótica de Lima. This was represented by a group of scientific men, headed by Hipólito Unanue and among whom José Gregorio Paredes played a leading role. The second strand was of a legal-philosophical character due to its emphasis on concepts like freedom and sovereignty, and was forged in discussions over the possibility of either a constitutional monarchy or a strictly republican regime whose main spokesman was the Trujillo lawyer José Faustino Sánchez Carrión. Militarized republicanism, the third category of thought discussed in this article, arose as a response to the problem of the war against the Spanish empire and was the brainchild of soldiers of the Republic like Domingo Nieto.

    El artículo se propone explorar tres de las vertientes del republicanismo peruano entre 1821 y 1834. La primera, la «patria científica» que floreció en el seno de la Sociedad Patriótica de Lima y está representada por un grupo de hombres de ciencia liderados por Hipólito Unanue, entre los que destacó José Gregorio Paredes. La segunda vertiente, de corte jurídico- filosófico por su énfasis en conceptos como los de libertad y soberanía, se irá gestando en la discusión entre la opción de una monarquía constitucional y otra de carácter estrictamente republicano, siendo su vocero el abogado trujillano José Faustino Sánchez Carrión. El republicanismo militarizado, que es la última categoría que se discute en este trabajo, surge como una respuesta al problema de la guerra contra el imperio español y es construida por «soldados de la República» como Domingo Nieto.

    ón Familiar, en Colombia se calculan más de 400.000 abortos al año lo que arroja un promedio de más de 1.000 abortos diarios, y en América Latina se registra una cifra de 5 millones de abortos anuales que da como promedio que de cada 1.000 embarazos abortan 300 mujeres.

    La situación se torna más alarmante al pensar que el 53% de la población mundial vive en países que permiten el aborto, lo que arroja una relación de 4 abortos por cada 10 nacimientos, el 38% vive en naciones cuya permisividad está condicionada a circunstancias especiales y sólo en e19% de las naciones está prohibida esta práctica, entre los cuales se encuentra nuestro país, lo anterior nos da una magnitud de la gravedad de esta situación. Pues bien; a este gravísimo problema social se le ha venido mirando desde varias perspectivas: la médica, la religiosa, la socio económica, la cultural, la educativa, la sociológica y la antropológica.

    La Iglesia como abanderada de la protección de la vida ha considerado el aborto como un procedimiento ilícito, no porque desea imponer una moral particular a una sociedad entera, como dice el escritor y filósofo español Julián Manas sino porque se trata de exterminar la vida de un ser humano en desarrollo si no lo matamos, de aquí la posición clara de la Iglesia en defensa de la vida y lo que atañe a la profesión médica a la que más se le ha involucrado en su estudio y tratamiento, y en particular a la especialidad de la Gineco-Obstetricia que es la rama de la medicina con más conocimientos científicos al respecto y es a sus profesionales a quienes se responsabiliza y obliga a dar protección y asistencia a la vida, antes y después de nacer.

    Por tales razones ha predominado siempre el concepto de darle una solución médica de fácil definición a un problema profundamente socioeconómico, cultural y antropológico. Es como si quisiéramos considerar el delito de homicidio como un problema especialmente de los abogados. Es

    Full Text Available Nicaragua es un país con un nivel de escolarización relativamente bajo y el contexto material y social en las escuelas hace que la enseñanza de la lengua materna esté dominada por métodos de memorización y ejercicios de gramática del tipo “rellenar espacios”. Las formas de tratamiento escritas que se utilizan en contextos pedagógicos son únicamente el tú y el usted, a pesar de ser Nicaragua una zona voseante. El presente artículo pretenderá mostrar, a través de referencias a estudios sobre las formas de tratamiento en Nicaragua, análisis del uso de los tratamientos en la escritura, ejemplos de entrevistas de actitudes lingüísticas y de análisis de documentos pedagógicos, que hay una discrepancia entre la norma escrita y la norma hablada en cuanto a las formas de tratamiento tú y vos en Nicaragua. Esta discrepancia se puede explicar con las creencias en torno a las diferentes formas de tratamiento, pero también al revés: el uso contradictorio de parte de las autoridades educativas influirá en las creencias del pueblo en general acerca de las formas de tratamiento y así crece un clima de inseguridad de la corrección de su propia habla. En última instancia tal contradicción puede ser un obstáculo para la enseñanza de la lengua materna y el prestigio lingüístico del habla local.

    In this paper, we present timing variations detected for the TrES-5b exoplanet. To obtain necessary photometric data for this exoplanet, we have organized an international campaign for exoplanet searching based on the Transit Timing Variation (TTV) method. We managed to collect N light curves for TrEs-5b. On the basis of the obtained data, we detected timing variations with the period P ≍ 100 days. We carried out the N-body modelling by means of the three-body problem. We detected a perturbation of TrES-5b which can be caused by a second exoplanet in the TrES-5 system. We calculated possible masses and resonances of the objects: M ˜ 0.24 Mjup on the 1:2 Resonance and M ˜ 3.15 Mjup on the 1:3 Resonance.

    Full Text Available OBJETIVO: Analizar los factores sociales asociados al estado de salud de hombres mayores de 60 años que viven en contextos de pobreza en áreas rurales de México. MATERIAL Y MÉTODOS: De febrero a octubre de 2002 se llevó a cabo un estudio transversal, descriptivo, con una muestra intencional de 392 adultos mayores residentes de zonas rurales de los estados de Guerrero, Morelos y Jalisco, utilizando un cuestionario especialmente diseñado y piloteado con anterioridad. Las variables de estudio incluyeron características sociodemográficas, bienestar generalizado, problemas de salud, consumo de algunos alimentos y algunos indicadores de salud mental, fuerza personal y apoyo social. Utilizando el paquete estadístico SPSS v. II.I se llevaron a cabo pruebas de Ji cuadrada de Pearson para variables categóricas; para analizar el consumo diferencial de alimentos se hicieron pruebas de ANOVA de una vía. RESULTADOS: Los ancianos de este estudio eran casados o viudos y tenían un promedio de seis hijos. Los ancianos de Morelos informaron haber padecido un mayor número de enfermedades y haber tenido un consumo más alto de bebidas alcohólicas, en comparación con los ancianos de los otros dos estados. De la muestra total, 60% notificaron el uso tanto de remedios caseros como de medicamentos para aliviar sus malestares de salud. Más de la mitad no recibía apoyo familiar adecuado. CONCLUSIONES: Los resultados de este estudio sugieren que el proceso de envejecimiento entre los hombres participantes es percibido como una carga, fundamentalmente debido al contexto de pobreza en que viven. La falta de ingresos suficientes y acceso a servicios de salud a través de planes de pensión y jubilación adecuados para los ancianos que viven en pobreza, es un problema que requiere de atención inmediata.OBJECTIVE: To analyze the social factors associated with the health status of elderly men, 60 years and older, who live in poverty in the rural areas of Mexico

En primer lugar se analiza el proceso de construcción social del propio concepto de “infancia y adolescencia en dificultad”, a la luz de los cambios que se han producido, especialmente a lo largo del último siglo, en las ciencias sociales y su repercusión en la formación de una idea de infancia en el imaginario colectivo. En segundo término, se aborda la condición de ser niño o adolescente en la llamada “sociedad del riesgo”, caracterizada, entre otras cosas, por la incertidumbre y los deseos de alcanzar un cierto control sobre los peligros percibidos como potenciales. La percepción de los riesgos para la infancia en la sociedad tiene dos caras: por un lado los peligros a los que están expuestos y por otro aquellos que causan, esto es, lo que nos amenaza. Para conjurar estos riesgos se exige mayor control por parte de las instituciones que regulan la vida de los niños (la familia, la escuela o el sistema de protección. El resultado es una restricción de la autonomía de los niños, niñas y adolescentes, que contrasta con las expectativas de que, como “hijos de la modernidad”, sean capaces de elegir sus propios caminos de autorrealización.-------------------------------------------------------------------This article tries to be an invitation to a journey in which the shared safeties taken for granted on the reality of the children and today teenagers, are being put in question, looking for other alternative explanations, which enable us to approach the study of the lives of the

    Malaria is highly endemic in Yunnan Province, China, with the incidence of malaria being highest along the Sino-Burmese border. The aim of our study was to determine whether genetic polymorphisms are associated with the prevalence of malaria among Chinese residents of the Sino-Burmese border region. Fourteen otherwise healthy people with glucose-6-phosphate dehydrogenase (G6PD) deficiency, 50 malaria patients, and 67 healthy control subjects were included in our cross-sectional study. We analyzed the frequency of the G3093T and T520C single-nucleotide polymorphisms (SNPs) of CR1. Logistic regression was used to calculate the prevalence odds ratio (POR) and 95% confidence interval (CI) of malaria for the T520C SNP of CR1 and SNPs of G6PD, IL-4, IL-4R, IL-1A, NOS, CD40LG, TNF, and LUC7L. The frequency of the 3093T/3093T genotype of CR1 in the malaria group (0.16) was significantly higher than that in the control group (0.045, P G6PD deficiency group (0.43, P G6PD-deficiency group (0.36, P G6PD did not significantly influence the prevalence malaria (P > 0.05). A GTGTGTC haplotype consisting of IL-1A (rs17561), IL-4 (rs2243250), TNF (rs1800750), IL-4R (rs1805015), NOS (rs8078340), CD40LG (rs1126535), and LUC7L (rs1211375) was significantly associated with the prevalence of malaria (POR: 1.822, 95% CI: 0.998-3.324). The 3093G/3093G and 520T/520T genotypes are the predominant genetic variants of CR1 among Chinese residents near the Sino-Burmese border, and the T allele of T520C is associated with the prevalence of malaria in this region. Although G6PD deficiency does not protect against malaria, it may diminish the association between malaria and the CR1 polymorphisms in this population. The GTGTGTC haplotype is also associated with the prevalence of malaria in this region.

    Earth System Documentation (ES-DOC) is an international project supplying high-quality tools & services in support of earth system documentation creation, analysis and dissemination. It is nurturing a sustainable standards based documentation eco-system that aims to become an integral part of the next generation of exa-scale dataset archives. ES-DOC leverages open source software, and applies a software development methodology that places end-user narratives at the heart of all it does. ES-DOC has initially focused upon nurturing the Earth System Model (ESM) documentation eco-system and currently supporting the following projects: * Coupled Model Inter-comparison Project Phase 5 (CMIP5); * Dynamical Core Model Inter-comparison Project (DCMIP); * National Climate Predictions and Projections Platforms Quantitative Evaluation of Downscaling Workshop. This talk will demonstrate that ES-DOC implements a relatively mature software development process. Taking a pragmatic Agile process as inspiration, ES-DOC: * Iteratively develops and releases working software; * Captures user requirements via a narrative based approach; * Uses online collaboration tools (e.g. Earth System CoG) to manage progress; * Prototypes applications to validate their feasibility; * Leverages meta-programming techniques where appropriate; * Automates testing whenever sensibly feasible; * Streamlines complex deployments to a single command; * Extensively leverages GitHub and Pivotal Tracker; * Enforces strict separation of the UI from underlying API's; * Conducts code reviews.

  7. Transcriptome analysis of chicken ES, blastodermal and germ cells reveals that chick ES cells are equivalent to mouse ES cells rather than EpiSC

    Full Text Available Pluripotent Embryonic Stem cell (ESC lines can be derived from a variety of sources. Mouse lines derived from the early blastocyst and from primordial germ cells (PGCs can contribute to all somatic lineages and to the germ line, whereas cells from slightly later embryos (EpiSC no longer contribute to the germ line. In chick, pluripotent ESCs can be obtained from PGCs and from early blastoderms. Established PGC lines and freshly isolated blastodermal cells (cBC can contribute to both germinal and somatic lineages but established lines from the former (cESC can only produce somatic cell types. For this reason, cESCs are often considered to be equivalent to mouse EpiSC. To define these cell types more rigorously, we have performed comparative microarray analysis to describe a transcriptomic profile specific for each cell type. This is validated by real time RT-PCR and in situ hybridisation. We find that both cES and cBC cells express classic pluripotency-related genes (including cPOUV/OCT4, NANOG, SOX2/3, KLF2 and SALL4, whereas expression of DAZL, DND1, DDX4 and PIWIL1 defines a molecular signature for germ cells. Surprisingly, contrary to the prevailing view, our results also suggest that cES cells resemble mouse ES cells more closely than mouse EpiSC.

    Full Text Available I- LA TRANSCULTURACIÓN A mayor edad, menos acuerdo me asiste con esta forma de crítica para la cual el desenvolvimiento de nuestra literatura, en el tiempo, fue y es, una especie de idilio. Tengo para mí que la literatura colombiana nació del resplandor de una gran lucha, habida cuenta de que cronistas y poetas contribuyeron, como conquistadores también, a la destrucción de las civilizaciones indianas, y con estas, de su cultura. A la sombra del nuevo idioma y los modos nuevos, que surgen del alumbramiento de las fundaciones, lo indiano acaba por ser solo un recuerdo. Y cuando el aborigen canta, es para dolerse de los símbolos europeos de la invasión. Los testimomos escasean. Pero, ¿no es suficiente acaso con esta cuarteta?

    2009-03-01

    The mind-blindness theory of autism spectrum conditions has been successful in explaining the social and communication difficulties that characterize these conditions but cannot explain the nonsocial features (the narrow interests, need for sameness, and attention to detail). A new theory, the empathizing-systemizing (E-S) theory, is summarized, which argues two factors are needed to explain the social and nonsocial features of the condition. This is related to other cognitive theories such as the weak central coherence theory and the executive dysfunction theory. The E-S theory is also extended to the extreme male brain theory as a way of understanding the biased sex ratio in autism. Etiological predictions are discussed, as are the clinical applications arising from the E-S theory.

  10. Mouse ES cell culture system as a model of development.

    2010-04-01

    Mouse embryonic stem (mES) cells are pluripotent stem cells derived from pre-implantation embryos. They are regarded as an essential tool for studying mouse development, as they provide a means for generating knock-out mouse lines. This, however, is not the sole utility of the mES cell system. They undergo differentiation in culture, mimicking the morphological differentiation of peri-implantation embryos from epiblast to egg-cylinder stage. Moreover, they retain the capacity to respond to triggers of differentiation toward trophectoderm and primitive endoderm by forced activation. For these reasons, mES cells can be regarded as a useful tool for analyzing molecular mechanisms underlying early mouse development.

La contestación a la pregunta sobre si la asistencia sexual es un derecho puede variar dependiendo del marco en el que nos desenvolvamos. Así, podemos estar hablando desde un marco estrictamente jurídico, desde un marco ético, o desde un marco a caballo entre ambos como es el de los derechos humanos. A partir de aquí, la pregunta sobre si la asistencia sexual es un derecho dependerá de la pregunta sobre qué es la asistencia sexual. La justificación de la asistencia sexual en relación con personas que no pueden realizar actividad sexual sobre su propio cuerpo puede encontrar una justificación ética de la mano de la teoría de las necesidades o de la mano de las Actividades Básicas de la Vida Diaria, e igualmente puede formar parte de los derechos sexuales o del derecho a elegir una forma de vida.

  19. Early specification of dopaminergic phenotype during ES cell differentiation

    2007-07-01

    Full Text Available Abstract Background Understanding how lineage choices are made during embryonic stem (ES cell differentiation is critical for harnessing strategies for controlled production of therapeutic somatic cell types for cell transplantation and pharmaceutical drug screens. The in vitro generation of dopaminergic neurons, the type of cells lost in Parkinson's disease patients' brains, requires the inductive molecules sonic hedgehog and FGF8, or an unknown stromal cell derived inducing activity (SDIA. However, the exact identity of the responding cells and the timing of inductive activity that specify a dopaminergic fate in neural stem/progenitors still remain elusive. Results Using ES cells carrying a neuroepithelial cell specific vital reporter (Sox1-GFP and FACS purification of Sox1-GFP neural progenitors, we have investigated the temporal aspect of SDIA mediated dopaminergic neuron specification during ES cell differentiation. Our results establish that SDIA induces a dopaminergic neuron fate in nascent neural stem or progenitor cells at, or prior to, Sox1 expression and does not appear to have further instructive role or neurotrophic activity during late neuronal differentiation of neural precursors. Furthermore, we show that dopaminergic neurons could be produced efficiently in a monolayer differentiation paradigm independent of SDIA activity or exogenous signalling molecules. In this case, the competence for dopaminergic neuron differentiation is also established at the level of Sox1 expression. Conclusion Dopaminergic neurons are specified early during mouse ES cell differentiation. The subtype specification seems to be tightly linked with the acquisition of a pan neuroectoderm fate.

    We present the development of a parallel Markov Chain Monte Carlo (MCMC) method called SAChES, Scalable Adaptive Chain-Ensemble Sampling. This capability is targed to Bayesian calibration of com- putationally expensive simulation models. SAChES involves a hybrid of two methods: Differential Evo- lution Monte Carlo followed by Adaptive Metropolis. Both methods involve parallel chains. Differential evolution allows one to explore high-dimensional parameter spaces using loosely coupled (i.e., largely asynchronous) chains. Loose coupling allows the use of large chain ensembles, with far more chains than the number of parameters to explore. This reduces per-chain sampling burden, enables high-dimensional inversions and the use of computationally expensive forward models. The large number of chains can also ameliorate the impact of silent-errors, which may affect only a few chains. The chain ensemble can also be sampled to provide an initial condition when an aberrant chain is re-spawned. Adaptive Metropolis takes the best points from the differential evolution and efficiently hones in on the poste- rior density. The multitude of chains in SAChES is leveraged to (1) enable efficient exploration of the parameter space; and (2) ensure robustness to silent errors which may be unavoidable in extreme-scale computational platforms of the future. This report outlines SAChES, describes four papers that are the result of the project, and discusses some additional results.

    In this work, the purification and characterization of an extracellular elicitor protein, designated AsES, produced by an avirulent isolate of the strawberry pathogen Acremonium strictum, are reported. The defense eliciting activity present in culture filtrates was recovered and purified by ultrafiltration (cutoff, 30 kDa), anionic exchange (Q-Sepharose, pH 7.5), and hydrophobic interaction (phenyl-Sepharose) chromatographies. Two-dimensional SDS-PAGE of the purified active fraction revealed a single spot of 34 kDa and pI 8.8. HPLC (C2/C18) and MS/MS analysis confirmed purification to homogeneity. Foliar spray with AsES provided a total systemic protection against anthracnose disease in strawberry, accompanied by the expression of defense-related genes (i.e. PR1 and Chi2-1). Accumulation of reactive oxygen species (e.g. H2O2 and O2˙̄) and callose was also observed in Arabidopsis. By using degenerate primers designed from the partial amino acid sequences and rapid amplification reactions of cDNA ends, the complete AsES-coding cDNA of 1167 nucleotides was obtained. The deduced amino acid sequence showed significant identity with fungal serine proteinases of the subtilisin family, indicating that AsES is synthesized as a larger precursor containing a 15-residue secretory signal peptide and a 90-residue peptidase inhibitor I9 domain in addition to the 283-residue mature protein. AsES exhibited proteolytic activity in vitro, and its resistance eliciting activity was eliminated when inhibited with PMSF, suggesting that its proteolytic activity is required to induce the defense response. This is, to our knowledge, the first report of a fungal subtilisin that shows eliciting activity in plants. This finding could contribute to develop disease biocontrol strategies in plants by activating its innate immunity. PMID:23530047

    Full Text Available Este trabajo se propone analizar el papel del útil (Zeug y su diferencia con la obra de arte en “El origen de la obra de arte” a la luz de lo desarrollado en Ser y tiempo. Mientras que “lo a la mano” se constituye por su estructura remisional que inaugura del Dasein, el arte “abre mundo”, es decir, abre una nueva red de significados, independientemente del sentido que le quiso dar el artista. Que el arte “muestra el ser del útil” no quiere decir que meramente muestra “la esencia de una bota”, sino la estructura remisional de “lo a mano”. El cuadro de las botas de Van Gogh funcionará como ejemplo para mostrar las diferencias entre la obra y el útil. A la luz de esta interpretación, analizaremos las críticas de Schapiro y Schaeffer a la lectura heideggeriana del cuadro del pintor holandés.

    Full Text Available En el espacio multiétnico y pluricultural del Paraguay colonial, cobraron un papel relevante ciertos individuos que actuaron como intermediarios entre las distintas tradiciones culturales y los intereses de los diferentes actores en juego. En el contexto de las reducciones, donde se generaron disputas por las presiones suscitadas a causa de las obligaciones y demandas coloniales, diversos actores apelaron a estrategias de acción en defensa de los indígenas, así como en beneficio propio. Entre estos se encontraban los líderes guaraníes, quienes por la posición que ocuparon, desempeñaron el papel no solo de puentes culturales sino también el de agentes políticos y económicos. Estos sujetos, por sus prácticas cotidianas, contribuyeron a conectar elementos de universos diferentes, desdibujando así la rigidez de los límites que el Estado colonial intentaba aplicar en algunos casos entre grupos de diverso origen socioétnico.

    Full Text Available Los estudios empíricos en economía suelen ser realizados mediante el uso de técnicas econométricas. Estas se componen de diversos elementos entre los que destacan la economía matemática, la probabilidad y la estadística así como el análisis de bases de datos económicas. El análisis econométrico apareció por primera vez a finales del siglo XIX. No obstante, no fue sino hasta la década de los 30 que su origen suele establecerse oficialmente. Desde entonces a la fecha, esta disciplina ha sufrido un sinfín de revoluciones, algunas de ellas muy dramáticas. Los objetivos, empero, siguen siendo los mismos: proveer del herramental adecuado al economista para que éste pueda llevar a cabo estudios económicos con base en datos estadísticos. El presente artículo propone una breve síntesis de la historia de la econometría así como una explicación de su utilidad en estudios sociales.Empirical Economics research is usually carried out using econometric techniques. The origins of econometrics are quite diverse. Roughly speaking the ingredients of this melting potare mathematical economics, probability and statistics and economic data. Econometrics studies appeared at the end of the XIX century although its official start can be placed in the 30s. Over these years, the discipline has undergone a number of silent –and not so silent revolutions. Its main purpose remains unchanged: provide economists with tools so they can study economic phenomena thru statistical data. This paper makes a brief review of the history of econometrics and provides an explanation of its usefulness in social studies.

    The scope of this work is to conduct the cross-cultural adaptation from Spanish to European Portuguese of a questionnaire to measure the degree of "Patient Knowledge about their Medications" (CPM-ES-ES). A method based on six steps was applied: 1. Translation into Portuguese, 2. Elaboration of the first consensus version in Portuguese; 3.Back-translation into Spanish; 4. Elaboration of the second consensus version (cultural equivalency); 5. Conducting the pre-test; 6. Evaluation of the overall results. A cross-culturally adapted questionnaire in European Portuguese that measures the degree of "Patient Knowledge about their Medications" is proposed. The pre-test confirmation obtained 100% agreement with the corrected version of the second consensus version after pre-testing. The methodology selected made it possible to cross-culturally adapt the Spanish version of the CPM-ES-ES questionnaire to the Portuguese version. Further studies should demonstrate the equivalence of the psychometric properties of the cross-cultural translation into Portuguese with the original version.

    We have been able to develop a stable nuclear transfer (NT) method in the mouse, in which donor nuclei are directly injected into the oocyte using a piezo-actuated micromanipulator. Although the piezo unit is a complex tool, once mastered it is of great help not only in NT experiments, but also in almost all other forms of micromanipulation. Using this technique, embryonic stem (ntES) cell lines established from somatic cell nuclei can be generated relatively easily from a variety of mouse genotypes and cell types. Such ntES cells can be used not only for experimental models of human therapeutic cloning but also as a means of preserving mouse genomes instead of preserving germ cells. Here, we describe our most recent protocols for mouse cloning.

    ES-DAF unit was introduced and studied in this paper. Without a costly air saturator, ES-DAF consists of an ejector and a static mixer between the pressure side and suction side of the recycle rotary pump. The bubble size distribution in this novel unit was studied by using a CCD imagination through a microscope. The bubble size decreased with the increase of cycle ratio or the decrease of superficial air-water ratio. These results suggest that smaller bubbles would be formed when the initial number of nucleation sites increase by enhancing the turbulence intensity in the saturation system. The bubble size distribution became lower and wider with the increase of saturation pressure because of more frequent bubble collision and coalescence.

    Full Text Available In this text, which comes from Chapter 3 of his book, Jacques Le Mouel completes the philosophical reflection about the entrepreneurial myth of effectiveness founded in the sophism: "What is effective is true. What is true is faie. Therefore, what is effective is fair". The fact that management is elevated to the category of paradigm for the economic model of Western society and the collapse of the economies of the East has led to neglect that, now, we ourselves are the modelo His analysis of the supposed neutrality of science and of the differences between ethics and morality, in the framework of the firm and its relations with society, lead him to conclude that it is not true that what is effective is fair, and that the firm cannot serve as a model for contemporary society, since the end does not justify the means.En este texto, que corresponde al capitulo 3 de su libro, Jaques Le Mouël completa la reflexión filosófica sobre el mito empresarial de la eficacia funadado en el sofisma: "Lo eficaz es verdadero. Lo verdadero es justo. Luego, lo eficaz es justo". El hecho de elevar la administración a la categoría de paradigma del modelo económico de la sociedad occidental y el hundimiento de las economías del Este han llevado a ignorar que, ahora, el modelo somos nosotros mismos. Su análisis de la pretendida neutralidad de la ciencia y las diferencias entre ética y moral, en el marco de la empresa y en sus relaciones con la sociedad, lo lleva a concluir que no es cierto que lo eficaz sea justo y que la empresa no puede servir de modelo a la sociedad contemporánea, pues el fin no justifica los medios.

    This paper describes the concept for augmenting the SEGIS Program (an industry-led effort to greatly enhance the utility of distributed PV systems) with energy storage in residential and small commercial applications (SEGIS-ES). The goal of SEGIS-ES is to develop electrical energy storage components and systems specifically designed and optimized for grid-tied PV applications. This report describes the scope of the proposed SEGIS-ES Program and why it will be necessary to integrate energy storage with PV systems as PV-generated energy becomes more prevalent on the nation's utility grid. It also discusses the applications for which energy storage is most suited and for which it will provide the greatest economic and operational benefits to customers and utilities. Included is a detailed summary of the various storage technologies available, comparisons of their relative costs and development status, and a summary of key R&D needs for PV-storage systems. The report concludes with highlights of areas where further PV-specific R&D is needed and offers recommendations about how to proceed with their development.

    Static suspension procedures stabilize and support paralyzed facial muscles and enhance facial symmetry, appearance, mastication, and speech production in patients with facial palsy. A variety of autografts and allografts have been used for static facial suspension, but each has its limitations, and few studies document the efficacy or benefit of one substance over another. Xenograft tissue scaffoldings potentially offer both the compatibility of autografts and the convenience of allografts. Pilot study to evaluate efficacy of Surgisis ES (Enhanced Strength) static facial suspension in a series of six patients with facial paralysis. Retrospective chart review, illustrative case series, and review of the literature. Six patients with facial paralysis were treated with the Surgisis ES facial sling procedure. Four patients achieved satisfactory results after the initial procedure. One patient was displeased with the esthetic outcome and required a revision procedure to increase the tautness of the implant. In the initial four cases, the sling was tunneled subcutaneously and sutured to the muscle. In two cases, the sling was tunneled subcutaneously and subperiosteally, thereby suspending all the soft tissue in the midface. Static facial suspension with Surgisis ES improved cosmesis and function in this limited pilot study. In particular, a two-plane dissection technique provided excellent results. Further studies need to be conducted to evaluate the ongoing benefit over time.

    2013-12-01

    Founded in 1801 at the Hôpital Saint-Louis, Paris, under Jean-Louis Alibert, the French School of Dermatology was initially structured around the French Society of Dermatology (1889) and the organization of two world congresses (Paris 1889, 1900). After World War I, the creation of dermatological societies in the provinces infused French dermatology with new energy. In 1922, the first congress of the French-speaking dermatologists further contributed to the public profile of dermatologists in France. The "Journées de Mars" were initiated in 1961 at the Hôpital Saint-Louis, and in 1975 they went on to become the "Journées dermatologiques de Paris". Pr. Jean Civatte played a key role in their creation and in their organization for 30 years. After 1979, since actual patients could no longer be presented, the organizers of the congress had to change the content of the meeting from clinical presentations to post-graduate teaching and clinical research. From its origins in the form of meetings of French dermatologists in an intimate setting at the Hôpital Saint-Louis, the "Journées dermatologiques de Paris" grew within the ensuing decades into a major scientific event of the French-speaking dermatological community, bringing together more than 4000 participants in December each year.

    Full Text Available La Clasificación Internacional de las Enfermedades (CIE de la Organización Mundial de Salud (OMS es muy poco conocida en el ámbito de la psicología en España, y existe la falsa percepción de que su importancia es escasa en el campo de la salud mental. El propósito de este artículo es familiarizar a los psicólogos y otros profesionales en salud mental con el sistema de clasificación CIE, algo especialmente relevante al encontrarse actualmente en proceso de revisión. La OMS está haciendo un gran esfuerzo para crear una clasificación de trastornos mentales global, multicultural y multidisciplinar, centrándose en mejorar su utilidad clínica. Además, en la actual revisión de la CIE, la OMS ha adoptado el español como segunda lengua de trabajo, lo que da una gran oportunidad a los profesionales de la salud mental de España y otros países hispanohablantes de implicarse activamente en el desarrollo de la próxima versión de la clasificación. Es importante que los psicólogos de países hispanohablantes conozcan la CIE y entiendan los grandes beneficios que pueden aportarles su conocimiento y utilización para integrarse plenamente como profesión sanitaria oficial, así como para equipararse en la práctica de la psicología al resto de Europa y de todo el mundo en términos de diagnóstico y clasificación de los trastornos mentales.

    Full Text Available Una retrospectiva lingüística permite afirmar que la acción de tutela del Derecho público constitucional tiene raíces en el Derecho privado romano. El término tutela proviene del latín tutelae, expresión usada en Derecho romano para hablar de la relación entre pupilo y tutor. Tal origen se soporta no sólo en la similitud textual de las dos instituciones, sino en el origen remoto del juicio de amparo mexicano en el Derecho romano, juicio que inspiró la tutela colombiana. El origen de la actual tutela tiene repercusiones en la forma como en Colombia se percibe la relación entre individuos y Estado. En efecto, desde 1991, estando la tutela en el corazón de la Constitución, se puede construir la siguiente comparación: Estado es a individuo como tutor es a pupilo. Con base en esta comparación, al Estado le corresponde la diligente administración de los bienes de los individuos en interés de éstos. No obstante esta consecuencia positiva, tal administración se da en virtud de que los individuos se estiman incapaces de tal tarea, situación diferente a la de los individuos dentro de un contrato social. Por tanto, la opción de una democracia participativa parece inalcanzable.

Méthodes Neuf professionnels de la santé (4 médecins de famille, 2 internistes, 1 infirmière praticienne, 1 infirmière autorisée et 1 pharmacienne) et 1 membre non votant (pharmacienne gestionnaire de projet) formaient le comité principal appelé le Lipid Pathway Committee (le comité). La sélection des membres s’est fondée sur la profession, le milieu de pratique et son emplacement. Les membres ont divulgué tous leurs conflits d’intérêts potentiels ou réels. Le processus d’élaboration des lignes directrices était itératif et s’appuyait sur des affichages en ligne, une révision détaillée des données probantes, des réunions par téléphone et en ligne. Le comité a cerné 12 questions prioritaires à répondre. Le groupe de révision des données probantes a répondu à ces questions. À la suite d’un examen des réponses, les principales recommandations ont été formulées par consensus du comité. Nous avons produit une ébauche des lignes directrices qui a ensuite été peaufinée, distribuée à un groupe de cliniciens (médecins de famille, autres spécialistes, pharmaciens, infirmières et infirmières praticiennes) et à des patients pour obtenir de la rétroaction, la réviser en conséquence et le comité l’a ensuite finalisée.

    In this article, we compare optical light curves of two SN2002es-like Type Ia supernovae (SNe), iPTF14atg and iPTF14dpk, from the intermediate Palomar Transient Factory. Although the two light curves resemble each other around and after maximum, they show distinct early-phase rise behavior in the r-band. On the one hand, iPTF14atg revealed a slow and steady rise that lasted for 22 days with a mean rise rate of 0.2-0.3 mag day-1, before it reached the R-band peak (-18.05 mag). On the other hand, iPTF14dpk rose rapidly to -17 mag within a day of discovery with a rise rate \\gt 1.8 {{mag}} {{{day}}}-1, and then rose slowly to its peak (-18.19 mag) with a rise rate similar to iPTF14atg. The apparent total rise time of iPTF14dpk is therefore only 16 days. We show that emission from iPTF14atg before -17 days with respect to its maximum can be entirely attributed to radiation produced by collision between the SN and its companion star. Such emission is absent from iPTF14dpk probably because of an unfavored viewing angle, provided that SN2002es-like events arise from the same progenitor channel. We further show that an SN2002es-like SN may experience a dark phase after the explosion but before its radioactively powered light curve becomes visible. This dark phase may be lit by radiation from supernova-companion interaction.

    Children acquire /-z/ syllabic plurals (e.g., bus es) later than /-s, -z/ segmental plurals (e.g., cat s, dog s). In this study, the authors explored whether increased syllable number or segmental factors best explains poorer performance with syllabic plurals. An elicited imitation experiment was conducted with 14 two-year-olds involving 8 familiar disyllabic target plural nouns, half with syllabic plurals (e.g., bus → bus es) and half with segmental plurals (e.g., letter → letter s). Children saw pictures of the target items on a computer and repeated prerecorded 3-word-utterances with the target word in utterance-medial position (e.g., "The buses come") and utterance-final position (e.g., "Hear the buses"). Acoustic analysis determined the presence or absence of the plural morpheme and its duration. Children had more trouble producing syllabic plurals compared with segmental plurals. Errors were especially evident in the utterance-medial position, where there was less time for the child to perceive/produce the word in the absence of phrase-final lengthening and where planning for the following word was still required. The results suggested that articulatory difficulties-rather than a word length effect-explain later acquisition of syllabic plurals relative to segmental plurals. These findings have implications for the nature of syllabic plural acquisition in children with hearing impairments and specific language impairment.

    Full Text Available Diversos estudos têm demonstrado que, nas últimas décadas, mudanças nos hábitos alimentares vêm ocorrendo e que a proliferação de alimentos com diferentes finalidades passou a exigir do consumidor um alto nível de informação. Este artigo tem por objetivo principal investigar os fatores que influenciam a compra de alimentos infantis, observando especialmente os significados atribuídos por mães às informações nutricionais. Foram entrevistadas mães de diferentes níveis de escolaridade, renda, profissão e bairro de residência na cidade do Rio de Janeiro. O tratamento dos dados coletados ocorreu por meio da análise de conteúdo e, ao longo das entrevistas, foram questionados, por exemplo, quais fatores as mães entrevistadas consideravam importantes ao comprar alimentos para seus filhos e se tinham o costume de consultar as tabelas nutricionais dos alimentos no supermercado quando os estavam comprando. Adicionalmente, buscamos compreender o que, na perspectiva das mães, significam “alimentos pouco saudáveis” e qual conceito tinham sobre alimentos “nutritivos” e “saudáveis” - investigando se seriam sinônimos ou não. A partir de tais procedimentos, os resultados mostram que os três principais fatores que influenciam a compra de alimentos para os filhos são: i preço; ii marca; e iii a influência dos filhos. As interpretações a respeito das informações nutricionais puderam ser agrupadas em cinco categorias, quais sejam: 1 comprando besteira; 2 nutritivo versus saudável; 3 comer bem; 4 fatores importantes ao comprar alimentos para os filhos; e 5 informações nutricionais na intenção de compra.

Diante da possibilidade de diferenças na sensibilidade e na reprodutibilidade das medidas obtidas nos traçados, o presente estudo teve como objetivo comparar os parâmetros eletrocardiográficos de cães, obtidos por dois sistemas. Foram avaliados dois diferentes softwares computadorizados, o Wincardio Micromed® (WIN e o modelo TEB ECGPC® (TEB. Quarenta e dois cães hígidos, de diferentes raças (Cocker Spaniel, Daschund, Labrador, Pinscher, Pit Bull Terrier Poodle, Schnauzer, Shit Tzu, Yorkshire e sem raça definida, machos e fêmeas e com idade entre 4 meses e 16 anos foram agrupados segundo o peso e examinados pelos dois sistemas. As medidas eletrocardiográficas dos diferentes traçados foram analisadas na derivação DII. Os resultados indicaram que o sistema TEB apresentou maior sensibilidade na obtenção das medidas de duração da onda P e do complexo QRS, enquanto o sistema WIN foi mais sensível para determinar as medidas de amplitude dos mesmos parâmetros. Os animais de maior porte (26-37kg apresentaram maior variância nas medidas de duração e amplitude de onda P e duração do complexo QRS em comparação aos cães de médio (14-25kg e pequeno (1-13kg porte. O achado de diferenças entre os sistemas testados deve ser levado em consideração ao se empregar os diversos equipamentos para diagnóstico por meio de ECG-C na rotina clínica, de modo a evitarem-se divergências na interpretação dos exames entre diferentes prestadores de serviços veterinários.

    Full Text Available Taiwan media reflects the diversity and chaos of Ideology after the political reform from the end of 1980’s when the leader of Taiwan Chiang Ching-kuo announced the lifting of martial law on July 15, 1987. The democracy promoted the exchanging situation between Taiwan and Mainland China. The importance of Taiwan’s geopolitical position is disappearing by time. To integrate into the broadened AsianPacific region in the era of China’s uprising and Taiwan’s closed economic cooperation with Mainland China under its military threat is a new trend for Taiwan’s foreign policy. With the returning back of Putin to the presidency of Russia and his Asian cooperation strategy, Taiwan could understand the role of Russia appropriately to think about how to participate in this regional cooperation and consolidate the national security in the cross-strait region. The attitude of Russia toward the SCO should be paid attention to from the side of Taiwan authority. The author found that in the bigger geopolitical pattern in Asian-Pacific region that Russia plays more and more stable and positive role in the regional security under the competition with USA. The competition between USA and Russia is the new world geopolitical pattern for both Taiwan and Mainland China. This paper is divided into two parts from the aspect of Taiwan political and geopolitical changes to examine the problems of the cross-strait relations and SinoRussian relations under the theme of SCO in East Asia. The author assumes that Russia’s Asian Strategy will strengthen Russia’s influence on the cross-strait relations deeply and Russia will play the more and more important role in regional security and economic cooperation in East Asia.

    2008-12-01

    Full Text Available El uso generalizado de la expresión “justicia global” indica un cambio en la estructura del discurso moral. Tradicionalmente, las relaciones internacionales se consideraban como algo distinto de la justicia nacional. Antes se centraban en las interacciones entre los Estados, y luego se consideró el diseño del orden institucional nacional a la luz de sus efectos sobre los ciudadanos. Ese análisis moral institucional se empieza a aplicar a los arreglos institucionales supranacionales, hoy más influyentes e importantes en la vida de las personas. La perspectiva tradicional sugería acuerdos justos entre los Estados. La nueva perspectiva muestra que el orden institucional global es injusto pues enriquece a las élites de los países ricos y pobres, y perpetúa la opresión y el empobrecimiento de las mayorías.

    Environmental, Safety and Health (ES&H) issues became an important design consideration during the development of the W89 warhead for the SRAM 11 (Short-Range Attack Missile) missile. An action plan was developed to handle these issues at all the production agencies and at both the system and the component level. The main thrust was in the area of solvent substitution, in particular for solder flux removal. The cleaner d-limonene followed by an isopropyl alcohol rinse was selected for applications were the traditional cleaners were 1,1,1 trichloroethane or trichloroethylene. Compatibility testing rather than efficacy testing dominated the development effort. In addition to other solvent substitution applications, organic materials that were free of toluene diisocynate (TDI), and methylene dianiline (MDA) were explored for use in the W89.

    Full Text Available A cross-sectional survey of agricultural areas, combined with routinely monitored mosquito larval information, was conducted in urban Dar es Salaam, Tanzania, to investigate how agricultural and geographical features may influence the presence of Anopheles larvae. Data were integrated into a geographical information systems framework, and predictors of the presence of Anopheles larvae in farming areas were assessed using multivariate logistic regression with independent random effects. It was found that more than 5% of the study area (total size 16.8 km2 was used for farming in backyard gardens and larger open spaces. The proportion of habitats containing Anopheles larvae was 1.7 times higher in agricultural areas compared to other areas (95% confidence interval = 1.56-1.92. Significant geographic predictors of the presence of Anopheles larvae in gardens included location in lowland areas, proximity to river, and relatively impermeable soils. Agriculture-related predictors comprised specific seedbed types, mid-sized gardens, irrigation by wells, as well as cultivation of sugar cane or leafy vegetables. Negative predictors included small garden size, irrigation by tap water, rainfed production and cultivation of leguminous crops or fruit trees. Although there was an increased chance of finding Anopheles larvae in agricultural sites, it was found that breeding sites originated by urban agriculture account for less than a fifth of all breeding sites of malaria vectors in Dar es Salaam. It is suggested that strategies comprising an integrated malaria control effort in malaria-endemic African cities include participatory involvement of farmers by planting shade trees near larval habitats.

    2004-12-01

    Full Text Available This article discusses some women' s movements in Morocco. It intends to demonstrate that the usual model that is used to explain women' s movements in the Arab World is not valid This model considers two kinds of women's movements: on the one hand, Western feminist movements, occidentalists, and on the other, Islamist movements, which are theoretically more authentic but also more repressive. Through the analysis of the positions adopted by Islamist and Feminist groups toward juridical changes of Mudawana, as well as the constructions of "womanhood" in these groups, the article shows how this dichotomous model oversimplifies the explanation of these processes. Furthermore, the use of this model in the research is not neutral. It has political consequences, such as the primitivization of the other. Ethnography makes possible other approaches to the topic and allows us to build a more nuanced interpretation.

    El presente artículo analiza los movimientos de mujeres en Marruecos, confrontándolos a lo que viene siendo el esquema habitual de tratamiento: movimientos feministas, de tipo occidental, frente a movimientos islamistas, más "auténticos", pero de carácter represivo. A través de un análisis de los cambios jurídicos en Marruecos, así como de los modelos de "mujer" que defiende cada movimiento, el artículo muestra que el esquema explicativo de la dicotomía de islamismo frente a feminismo para explicar la cuestión no es válido. Su uso no es neutro, y en ocasiones puede tener consecuencias perversas, que primitivizan al "otro". En cambio, el estudio de estos movimientos en el contexto social y político marroquí, puede arrojar luz sobre un problema que estimula, en ocasiones, y bloquea, en otras, el cambio en Marruecos.

    Full Text Available OBJETIVO: Estudar os efeitos da associação do adesivo cirúrgico de fibrina à técnica operatória da invaginação submucosa, em anastomoses esofagianas. MÉTODO: Trinta e dois cães submetidos à anastomose esôfago-esofágica foram alocados em dois grupos: I com sutura em doze pontos e II com sutura em quatro pontos e vedação com adesivo de fibrina. Os animais foram avaliados no sétimo e décimo-quarto dias de pós-operatório. Foram analisados: a evolução ponderal, o índice de estenose, a incidência de deiscências e fístulas, a presença de secreções na tela subcutânea, a presença de líquido intersticial, matriz protêica, celularidade, fibroblastos, fibras de colágeno e concentração de hidroxiprolina. RESULTADOS: O índice de estenose foi menor para os animais do grupo I no sétimo dia de observação. Nos animais do grupo II a incidência de deiscências, secreção serosa e purulenta foram signitivamente maiores aos sete e quatorze dias, enquanto a presença de fístulas foi maior no sétimo dia. Quanto à concentração tecidual de hidroxiprolina não houve diferença estatística entre os grupos. Os fibroblastos e fibras de colágeno tiveram presença mais acentuada no grupo II no décimo-quarto dia. Ocorreram quatro óbitos em animais do grupo II. CONCLUSÕES: A anastomose por invaginação submucosa-mucosa com vedação com adesivo de fibrina apresentou piores resultados que a anastomose convencional de doze pontos circunferenciais.

Adota-se uma abordagem histórico-cultural, associada à discussão sobre participação política em partidos políticos. Trata-se de um estudo de caso baseado na epistemologia qualitativa de Gonzalez Rey (2003a. Os dados foram obtidos entre abril/2011 e março/2013, por meio de questionário, redação, observação participante, conversações grupais e individuais com dirigentes do PSDB/ES. Os resultados revelam configurações subjetivas da participação política singulares, construídas em torno de aspectos como: o constrangimento em assumir a participação política; sentir-se e não sentir-se dirigente; admirar ou criticar os quadros do partido; decepções com o sistema partidário brasileiro; desejo de adequações na gestão do partido e da política no Brasil. Conclui-se que motivações, barreiras e constrangimentos dos dirigentes geram ambiguidades, levando-os ao dilema entre participar (de maneiras distintas ou não da política.

    Purpose: The aim of this study is to assess the effectiveness and safety of the use of Vasoseal ES collagen plug in heavenly anti coagulated patients with risk of complications at the vascular access site who had undergone vascular radiological intervention. Materials and methods: Between January 2002 and March 2003 180 consecutive transfemoral arterial accesses in 169 patients subjected to vascular radiological procedures were performed (bilateral access was performed in 11 patients): 140 percutaneous transluminal angioplasties and 40 transarterial chemoembolisations. All the patients who underwent angioplasty were given 3,000 IU of sodic heparin intravenously during the procedure and later a prolonged antiaggregant therapy was undertaken (ticlopidine 500 mg/day and aspirin 150 mg/day). The sheaths were removed at the end of the surgical manoeuvre and two cartridges of collagen were positioned on the external surface of the artery. The mean values of platelets and partial thromboplastin time were 42,000/ml and 170 s, respectively, in cirrhotic patients against 250,000/ml and 200 s in patients with peripheral arteriopathy. The next day a colour Doppler examination was performed at the puncture site. Results: The technique proved successful in 89.4% of cases (161/180). In 19/180 vascular accesses placement of the haemostatic cartridges was not possible owing to the inability to compress the common femoral artery proximal to the release site (4/19), owing to a pre-existing haematoma (5/19) and owing to the limited presence of subcutoma (5/19) and owing to the limited presence of subcutaneous tissue (10/19). The mean time required for the placement of Vasoseal ES was 4 min. The mean time to haemostasis was 6 min. The mean time to mobilisation was 4 hr. Only in two patients was there an onset of a pseudoaneurysm of the right common femoral artery-, the lesions were treated with ultrasonography-guided compression. In addition, 16 small local haematomas were recorded. In

  12. Advances in SELEX ES infrared detectors for space and astronomy

    2017-11-01

    Selex ES produces a wide range of infrared detectors from mercury cadmium telluride (MCT) and triglycine sulfate (TGS), and has supplied both materials into space programmes spanning a period of over 40 years. Current development activities that underpin potential future space missions include large format arrays for near- and short-wave infrared (NIR and SWIR) incorporating radiation-hard designs and suppression of glow. Improved heterostructures are aimed at the reduction of dark currents and avalanche photodiodes (APDs), and parallel studies have been undertaken for low-stress MCT array mounts. Much of this development work has been supported by ESA, UK Space, and ESO, and some has been performed in collaboration with the UK Astronomy Technology Centre and E2V. This paper focuses on MCT heterostructure developments and novel design elements in silicon read-out chips (ROICs). The 2048 x 2048 element, 17um pitch ROIC for ESA's SWIR array development forms the basis for the largest cooled infrared detector manufactured in Europe. Selex ES MCT is grown by metal organic vapour phase epitaxy (MOVPE), currently on 75mm diameter GaAs substrates. The MCT die size of the SWIR array is 35mm square and only a single array can be printed on the 75mm diameter wafer, utilising only 28% of the wafer area. The situation for 100mm substrates is little better, allowing only 2 arrays and 31% utilisation. However, low cost GaAs substrates are readily available in 150mm diameter and the MCT growth is scalable to this size, offering the real possibility of 6 arrays per wafer with 42% utilisation. A similar 2k x 2k ROIC is the goal of ESA's NIR programme, which is currently in phase 2 with a 1k x 1k demonstrator, and a smaller 320 x 256 ROIC (SAPHIRA) has been designed for ESO for the adaptive optics application in the VLT Gravity instrument. All 3 chips have low noise source-follower architecture and are enabled for MCT APD arrays, which have been demonstrated by ESO to be capable of

    Full Text Available Las ciencias sociales y las ciencias de la evolución elaboraron nociones de la cultura, cuyas particularidades respectivas estimularon uno de los debates mas controvertidos de la antropología. Vista por las ciencias sociales, la noción de cultura estuvo en un principio inspirada por la noción de progreso y por la doctrina de la evolución, antes que la naturaleza biológica del hombre llegue a estar disociada de sus realizaciones culturales. Sin embargo permanecen los universales, esas marcas permanentes que transcienden los particularismos culturales que los antropólogos buscan desde los años treinta y que los reencuentra la antropología cognitiva actual bajo otras formas. Ellos no dejan de evocar las sujeciones que implica la tesis de una base genética de los comportamientos. L'etologia constituida como disciplina alrededor de los años 30, habiendo analizado el mecanismo de los comportamientos de comunicación codificados, lanzo las bases de una genética de los "instintos" y se dedico a reconstruir su filigénesis y su ontogénesis. De estas investigaciones nacieron los fundamentos de una teoría de la cultura que toma prestado los mecanismos evolutivos del neo-darwinismo. Esta teoría, la sociobióloga, luego de amplias investigaciones en el dominio de los comportamientos sociales animales, extrapola esos principios y sus teoremas al caso de la evolución humana e interroga a los antropólogos sobre aquello que para ellos es lo mas especifico: los comportamientos culturales humanos. Podemos extrapolar los comportamientos animales a los comportamientos humanos? Investigaciones mas profundas sobre ciertos comportamientos de base como los comportamientos reproductivos, parecen indicar respuestas que varían según las culturas y según los estratos sociales. En todo caso, revocan la noción de comportamientos universales y si no invalidan que existe una especie de "raíz" animal a numerosos comportamientos elementales, estas indican

    Full Text Available La ciencia está en el origen del trabajo social. En efecto, el objetivo que perseguía Mary Richmond al conceptualizar la disciplina de trabajo social consistía en reemplazar las creencias religiosas por un enfoque racional. Así pues, el conocimiento científico se inscribe en el corazón del trabajo social desde el principio. Dicho esto, las grandes teorías son menos útiles en la práctica de una profesión cuya finalidad es ayudar a las personas que viven las situaciones más diversas. Esta es la razón por la cual el trabajo social se construye a partir de una base ecléctica: el trabajador social eficaz toma de un vasto conjunto de nociones, en apariencia dispares, aquellas que mejor se adaptan a la situación. Ahora bien, ¿cómo enseñar este conocimiento práctico a los estudiantes de trabajo social? Este artículo trata de estas cuestiones y propone algunas pistas de reflexión. Science is closely related to social work, from its very origin. In fact, with the conceptualization of social work, Mary Richmond’s objective was to replace religious beliefs by a more rational approach. Thus, right from its beginning, the scientific knowledge was at the core of social work. This being said, grand theories are less appropriate to the practice of social work because this profession deals with persons living in particular situations. That is why social work is built upon an eclectic basis : social worker has to draw from a vast array of notions and theories to borrow bits and pieces which will help to explain and attenuate problem experienced by persons. Now, this practical knowledge can be taught to students in social work? This article deals with these questions and proposes some reflections.

    Full Text Available La cuestión de la eficacia del terrorismo es de gran relevancia política para los perpetradores, las víctimas y la sociedad en general. Evaluar la eficacia de la violencia política requiere analizar con detalle la gama de objetivos de los grupos terroristas y distinguir entre los niveles estratégicos y tácticos. Si bien la mayoría de las organizaciones clandestinas no logra alcanzar sus objetivos a largo plazo, sí consigue algunos éxitos durante el proceso. La capacidad del terrorismo para producir los efectos deseados dependerá también de otras variables y parámetros contextuales. El éxito táctico y estratégico de una campaña violenta depende de: 1 la capacidad y la fuerza de los perpetradores; 2 el tipo de objetivos, y 3la capacidad y la resistencia de la sociedad objetivo.

Consideramos, en cambio, que este conflicto no debe pensarse como un episodio aislado, sino como parte de un contexto más amplio conformado por la problemática aborigen en el periodo de consolidación del Estado nacional. Entendemos la noción de "rebelión" como un proceso complejo en el que se ponen en juego aspectos políticos, económicos, sociales y religiosos, vinculándose tanto a una protesta contra las imposiciones del Estado como a un movimiento de tipo milenarista. Analizaremos dicha rebelión a partir de la prensa de la época, en la cual identificamos diferentes interpretaciones sobre la misma, así como diversas concepciones sobre la cuestión indígena que se planteaban entre distintos sectores de la sociedad mayor.In this article we reconstruct the rebellion of the mocovi people from San Javier in 1904, which was conceived at that time as an invasion of a group of savages, whose intentions were only to loot and destruct the town. On the contrary, we consider that this was not an isolated confrontation, but part of the context of conflicts between aboriginal people and the national State during its consolidation period. We understand the concept of "rebellion" as a process that articulates political, economical, social and religious aspects, in a way that allow us to think of this protest as a resistance against the impositions of the State and also as a millenarist movement. We will analyse this rebellion based on the information available on the contemporary press, where we identified diverse interpretations of the aboriginal conflicts within different sectors of the wider society.

    Full Text Available RAC3 fue caracterizado originalmente como un coactivador de receptores nucleares que se encuentra en cantidades limitantes en células normales, aunque sobreexpresado en tumores y es además coactivador de NF-?B. Si bien se desconocen los mecanismos involucrados en el aumento de su expresión, se sabe que induce resistencia a apoptosis. En este trabajo se investigó si RAC3 podría contribuir al desarrollo tumoral por otros mecanismos y si la citoquina TNF-a, que se encuentra en alto título en pacientes con cáncer, podría favorecer el aumento en la expresión de RAC3. Se observó que el aumento en la expresión del coactivador por transfección de células no tumorales de riñón embrionario humano HEK293 no solo aumenta significativamente la proliferación en presencia de suero, sino además en ausencia de factores de crecimiento. También se indujo la transformación celular dando un fenotipo con crecimiento independiente de anclaje similar a lo observado para células tumorales. El tratamiento de las células HEK293 en cultivo con TNF-a indujo un aumento en los niveles proteicos de RAC3 respecto de las células sin estímulo y este efecto fue inhibido por pretratamiento con un inhibidor específico de la activación de NF-?B, indicando que la activación de este factor de transcripción está involucrada en la acción de la citoquina. Se concluye que RAC3, además de su acción anti-apoptótica, es un factor transformante que promueve la proliferación y el crecimiento independiente de anclaje, cuyos niveles podrían ser aumentados en la tumorigénesis, probablemente vía las citoquinas inflamatorias involucradas en la respuesta anti-tumoral.

Para entender las diferentes posiciones, se analizan, además, los conceptos de profesionalismo y profesionalización, y se destaca la importancia de la formación como un proceso de desarrollo personal y profesional. Por último se tratan aspectos relacionados con la salud laboral y las enfermedades profesionales.ABSTRACT: This article proposes to rethink some of the key issues of the recent debate about the teaching profession, through the analysis of three specific aspects: What is a profession? What are its distinctive features? To what extent can we say that teachers are satisfying the demands of the profession? Although there is a general agreement about the need to improve the professional quality of teaching, there doesn't seen to be a way to achieve it. In order to understand the different points of view, there will also be an analysis of the notions of professionalism and professionalization, with an emphasis on the importance of formation as professional and personal development process. To conclude, the issues of laboral health and professional illnesses will be dealt with.

  9. ¿Qué es una emoción?

    Full Text Available Gregorio Marañón wrote relatively little about emotion. Nevertheless, he considered emotion to be “one of the most interesting problems of human life.” This article describes the basic brain processes of emotion that motivates living beings to follow patterns of behaviour whose ultimate meaning is the survival of the individual and the species. A description is given here of the emotional processing of sensory information. It is noted that any process of conscious learning and memory is always emotionally coloured. Finally, one of the main conclusions of this article is that there is no rational thought without a previous emotional process in the brain. There is no reason without emotion. This is a conclusion that would probably have amazed Professor Marañón.El Dr. Gregorio Marañón no escribió mucho sobre la emoción. Pero sí es cierto que consideró que se trataba de “uno de los problemas más interesantes de la vida humana”. En este artículo se describen los procesos cerebrales básicos de la emoción que nos alertan y motivan hacia la realización de conductas en cuyo significado último se encuentra la supervivencia del individuo y de la especie. Se describe el procesamiento emocional de la información sensorial. Se señala que todo proceso de aprendizaje y memoria consciente siempre viene coloreado emocionalmente. Y se destaca que el profesor Marañón posiblemente mostraría asombro ante una de las principales conclusiones de este artículo en las que se indica que no hay pensamiento sin una emoción previa que lo alimente. Que no hay razón sin emoción.

    Full Text Available Hay quienes piensan que el objetivo principal de la mercadotecnia es vender más, o bien, colocar productos y distribuirlos, o que es una herramienta para atraer a los clientes o inclusive para manipularlos. El objetivo del presente ensayo es reflexionar sobre el objetivo principal de esta disciplina, la cual es realmente una filosofía de vida empresarial. Se concluye que dicho objetivo es fomentar el intercambio voluntario entre dos o más partes que tienen algo que interesa a unos y a otros entre sí. El resultado de dicho intercambio, el cual es la clave en el proceso de la mercadotecnia, es lograr más ventas a través de satisfacer a los clientes y conseguir su lealtad mediante la identificación de sus necesidades y deseos, conjuntándolos con productos y servicios de calidad. Otra conclusión es que la satisfacción del cliente y las ventas, que para la empresa son objetivos, para la mercadotecnia son resultados del correcto fomento del intercambio voluntario en la gestión de negocios, el cual es su objetivo como disciplina en sí. Por otra parte, tampoco puede decirse que el mercadólogo sea un creador de necesidades ya que su papel es detectarlas y proponer los satisfactores para las mismas.

    Full Text Available Transcurridos los primeros dieciséis años del siglo veintiuno observamos que las producciones de sentido y los modos de ejercer, distribuir, moldear y almacenar los bienes simbólicos se transforman vertiginosamente. El contexto digital impone velocidad, plasticidad, inmediatez y visibilidad a las narraciones. Los relatos circulan por diversos soportes, mutando sentidos, provocando que el conocimiento, el arte, las informaciones sean apropiadas y resignificadas. Mientras tanto hay resistencias, instituciones que sostienen que las formas tradicionales deben continuar dada su validez comprobada. Así se da una yuxtaposición de intereses y tensiones entre prácticas y sentidos. Observaremos esta tensión para comprenderla, para ver y definir eso que culmina mientras algo nuevo, que aún no tiene una estructura precisa, comienza a surgir ¿Será que estas innovadoras alternativas tecnológicas facilitan la democratización del conocimiento, entendiendo que el uso de las tecnologías responde a fundamentos políticos y pedagógicos? A partir de una perspectiva comunicacional analizaremos la complejidad de la producción social de conocimiento, el uso de las tecnologías, los vínculos entre los sujetos partícipes en estos procesos y las múltiples disputas en juego. Detallar las coordenadas de espacio y tiempo permiten situar la producción y garantiza la comprensión del proceso. Una de las primeras cosas que aprendemos en las aulas de la universidad pública es que el conocimiento se sitúa históricamente. Desde la primera pregunta que se antepone a cualquier investigación comprendemos que las hipótesis son producto de un pensamiento crítico referido a constricciones económicas, políticas y socioculturales de la propia sociedad en la que se vive y se formulan dichas hipótesis. Las innovaciones en formatos y soportes de comunicación exigen resituar y adecuar las estrategias.

  14. Challenges in diagnosing paediatric malaria in Dar es Salaam, Tanzania.

    Malaria is a major cause of paediatric morbidity and mortality. As no clinical features clearly differentiate malaria from other febrile illnesses, and malaria diagnosis is challenged by often lacking laboratory equipment and expertise, overdiagnosis and overtreatment is common. Children admitted with fever at the general paediatric wards at Muhimbili National Hospital (MNH), Dar es Salaam, Tanzania from January to June 2009 were recruited consecutively and prospectively. Demographic and clinical features were registered. Routine thick blood smear microscopy at MNH was compared to results of subsequent thin blood smear microscopy, and rapid diagnostics tests (RDTs). Genus-specific PCR of Plasmodium mitochondrial DNA was performed on DNA extracted from whole blood and species-specific PCR was done on positive samples. Among 304 included children, 62.6% had received anti-malarials during the last four weeks prior to admission and 65.1% during the hospital stay. Routine thick blood smears, research blood smears, PCR and RDT detected malaria in 13.2%, 6.6%, 25.0% and 13.5%, respectively. Positive routine microscopy was confirmed in only 43% (17/40), 45% (18/40) and 53% (21/40), by research microscopy, RDTs and PCR, respectively. Eighteen percent (56/304) had positive PCR but negative research microscopy. Reported low parasitaemia on routine microscopy was associated with negative research blood slide and PCR. RDT-positive cases were associated with signs of severe malaria. Palmar pallor, low haemoglobin and low platelet count were significantly associated with positive PCR, research microscopy and RDT. The true morbidity attributable to malaria in the study population remains uncertain due to the discrepancies in results among the diagnostic methods. The current routine microscopy appears to result in overdiagnosis of malaria and, consequently, overuse of anti-malarials. Conversely, children with a false positive malaria diagnosis may die because they do not receive

    The majority of women with rheumatoid arthritis (RA) experience disease amelioration during pregnancy for unclear reasons. One possible explanation pursued and described here is whether the placenta produces a protein similar to the immunomodulating protein, ES-62, excreted by filarial nematodes. This protein has also been shown to reduce disease activity in animal models of RA. Eleven human placentas were prepared and a polyclonal anti-ES-62 antiserum was used to identify if any ES-62-like m...

    Full Text Available Foi realizado um estudo quantitativo e qualitativo dos plexos de Auerbach e Meissner do esôfago de quatro cães chagásicos sacrificados na fase aguda da infecção. As ganglionites e periganglionites do plexo de Auerbach variaram de discretas a moderadas, induzindo lesões neuronais significativas, principalmente em dois animais. Os gânglios do plexo de Meissner foram observados em pequeno número, impossibilitando qualquer análise. Miosite discreta ou moderada foi observada principalmente no terço inferior do esôfago, raramente associada a ninhos de amastigotas. A contagem de gânglios e neurônios não demonstrou desnervação. Apesar de em nenhum dos cães ter sido induzida a formação de megaesôfago, relatamos lesões do plexo de Auerbach e de miocélulas do esôfago de animais na fase aguda da infecção chagásica.

    Full Text Available Electroporation is used to induce homologous recombination in the genome of the murine ES (embryonic stem cells. Routinelly subconfluent ES cells are recommended to be used in such experiments. Electroporation of immunoglobulin specific targeting vectors with different length of homology leads to reduced number of selected colonies. The enrichment of double selected colonies is high and thus the amount of HM-1 ES cell colonies for the analysis is very low. Here we show that the electroporation of confluent HM-1 ES cells leads to an increased amount of simple and double selected colonies.

El deterioro cognitivo y los trastornos neuropsiquiátricos asociados a este síndrome no sólo tienen un impacto evidente sobre el paciente y sus allegados, sino que además demandan una atención sociosanitaria especializada que, habitualmente, se prolonga durante varios años. Tales circunstancias, sumadas al envejecimiento poblacional y al subsecuente aumento de la incidencia de demencia, hacen necesaria la implantación de terapias que, si bien actualmente no son capaces de curar o detener la dolencia, en muchos casos consiguen ralentizar su progresión y mejorar la calidad de vida de las personas afectadas.

    Science.gov (United States)

    Shiraki, Nobuaki; Kume, Shoen

    2015-05-01

    Embryonic stem (ES) and induced pluripotent stem (iPS) cells are pluripotent and can give rise to all cell types. ES/iPS cells have a unique transcriptional circuit that sustains the pluripotent state. These cells also possess a characteristically high rate of proliferation as well as an abbreviated G1 phase. These unique molecular properties distinguish ES and iPS cells from somatic cells. Mouse ES/iPS cells are in a high-flux metabolic state, with a high dependence on threonine catabolism. However, little is known about amino acid metabolism in human ES/iPS cells. Recently, we reported that human ES/iPS cells require high amounts of methionine (Met) and express high levels of Met metabolism enzymes (Shriaki N, et al: Cell Metabolism, 2014). Met deprivation results in a rapid decrease in intracellular S-adenosyl-methionine (SAM), triggering the activation of p53 signaling, reducing pluripotent marker gene NANOG expression, and poising human ES/iPS cells for differentiation, follow by potentiated differentiation into all three germ layers. However, when exposed to prolonged Met deprivation, the cells went to apoptosis. In this review, we explain the importance of SAM in Met metabolism and its relationship with pluripotency, cell survival, and differentiation of human ES/iPS cells.

    AsES (Acremonium strictum Elicitor and Subtilisin) is a novel extracellular elicitor protein produced by the avirulent isolate SS71 of the opportunist strawberry fungal pathogen A. strictum. Here we describe the activity of AsES in the plant-pathogen system Arabidopsis thaliana-Botrytis cinerea. We show that AsES renders A. thaliana plants resistant to the necrotrophic pathogen B. cinerea, both locally and systemically and the defense response observed is dose-dependent. Systemic, but not local resistance is dependent on the length of exposure to AsES. The germination of the spores in vitro was not inhibited by AsES, implying that protection to B. cinerea is due to the induction of the plant defenses. These results were further supported by the findings that AsES differentially affects mutants impaired in the response to salicylic acid, jasmonic acid and ethylene, suggesting that AsES triggers the defense response through these three signaling pathways.

  5. Zfp322a Regulates mouse ES cell pluripotency and enhances reprogramming efficiency.

    Full Text Available Embryonic stem (ES cells derived from the inner cell mass (ICM of blastocysts are characterised by their ability to self-renew and their potential to differentiate into many different cell types. Recent studies have shown that zinc finger proteins are crucial for maintaining pluripotent ES cells. Mouse zinc finger protein 322a (Zfp322a is expressed in the ICM of early mouse embryos. However, little is known regarding the role of Zfp322a in the pluripotency maintenance of mouse ES cells. Here, we report that Zfp322a is required for mES cell identity since depletion of Zfp322a directs mES cells towards differentiation. Chromatin immunoprecipitation (ChIP and dual-luciferase reporter assays revealed that Zfp322a binds to Pou5f1 and Nanog promoters and regulates their transcription. These data along with the results obtained from our ChIP-seq experiment showed that Zfp322a is an essential component of mES cell transcription regulatory network. Targets which are directly regulated by Zfp322a were identified by correlating the gene expression profile of Zfp322a RNAi-treated mES cells with the ChIP-seq results. These experiments revealed that Zfp322a inhibits mES cell differentiation by suppressing MAPK pathway. Additionally, Zfp322a is found to be a novel reprogramming factor that can replace Sox2 in the classical Yamanaka's factors (OSKM. It can be even used in combination with Yamanaka's factors and that addition leads to a higher reprogramming efficiency and to acceleration of the onset of the reprogramming process. Together, our results demonstrate that Zfp322a is a novel essential component of the transcription factor network which maintains the identity of mouse ES cells.

    be identified among Nazi members of the Parliament. The combination of these factors with war experience can give a more thorough and realistic picture. Therefore NSDAP had not the monopoly of war experience, but the one of youth and war experience. The Nazi MP’s were ten years younger than the other fractions of the Parliament. Moreover, a higher part of them were career soldiers, and soldiers’sons. They were also more attached to the countryside, by birth, profession their fathers’professions or the subjects they decided to study. All these criteria lead to question the usual excessive focus on War experience. Much more complex was the Nazi political commitment.¿Cuál fue el factor decisivo en el compromiso político de los nazis? En la literatura sobre este tema, la participación en la Primera Guerra Mundial se presenta frecuentemente como un factor esencial: esta participación habría sido creadora de una «cultura de guerra» que explicaría en gran parte la afiliación de los diputados nazis. El análisis del grupo nacional-socialista del parlamento alemán entre 1919 y 1933 parece confirmar esta hipótesis: se componía en un 80% de excombatientes. No obstante, esta explicación es insuficiente cuando se considera que los demás partidos también contaban entre sus filas con una proporción significativa de veteranos de guerra. Se puede sin embargo identificar atributos específicos de los parlamentarios nazis que, considerados en su conjunto y tomando en cuenta el impacto de la guerra y su herencia, dan una visión más compleja: si el grupo de diputados del NSDAP tenía un monopolio, éste no era el de la experiencia de guerra, sino mas bien el de su juventud. Sus diputados tenían diez años menos que el resto de los parlamentarios. Por otro lado, contaban con una proporción más elevada de militares de carrera, o de hijos de militares, así como con un número importante de hombres vinculados al mundo rural, ya sea por su lugar de nacimiento

    Full Text Available Qur'ānic verses on Paradise (especially Qur'ān, 55: 46-78, as well as the Kitāb waṣf al-firdaws by 'Abd al-Malik b. Ḥabīb, allow us to give specific meanings to the interpretation of Madinat al-Zahrā' as Paradise and to support it over other possible interpretations (although without necessarily eliminating the latter. On this basis, the variety and asymmetry of the wall decorations in the Hall of 'Abd al-Raḥmān III are explained, as well as how certain narratives on Madīnat al-Zahrā' came into being. The «green and manganese» decoration of the pottery produced in the town is given a new meaning and some considerations are offered on the name given to the town. A relationship can be established between Madīnat al-Zahrā' as Paradise and one of the doctrines attributed to Mundhir b. Sa'īd al-Ballūṭī, judge of Abd al-Raḥmān III from 339/950 until the death of the caliph. The silence of the Arab sources about this Paradisiac symbolism could be linked to the anecdote on how Mundhir b. Sa'īd censured 'Abd al-Raḥmān Ill's building activity. Finally, Madīnat al-Zahrā' has to be studied within the context of the political and religious struggle with the Fatimids, and more specifically taking into account the situation after the defeat of the «Man of the Donkey», who was presented as an eschatological figure by the Fatimids.

    Las aleyas coránicas sobre el Paraíso (y en especial Corán, 55: 46-78, así como el Kitāb waṣfal-firdaws de 'Abd al-Malik b. Habīb, nos permiten precisar mejor la interpretación «paradisíaca» de Madīnat al-Zahrā' y dotarla de sentidos concretos, mostrando sus ventajas sobre otras posibles (aunque no desechables. Se explica así no sólo la variedad, sino también la asimetría, de las decoraciones parietales del Salón de 'Abd al-Raḥmān III, se da sentido a cómo pudieron surgir una serie de relatos en tomo a Madīnat al-Zahrā', se puede plantear una nueva

    Destructive testing of an ES-3100 Shipping Container was completed by the Packaging Technology and Pressurized Systems organization within the Savannah River National Laboratory in order to qualify the ES-3100 as a candidate storage and transport package for applications at various facilities at the Savannah River Site. The testing consisted of the detonation of three explosive charges at separate locations on a single ES-3100. The locations for the placement were chosen based the design of the ES-3100 as well as the most likely places for the package to incur damage as a result of the detonation. The testing was completed at an offsite location, which raised challenges as well as allowed for development of new partnerships for this testing and for potential future testing. The results of the testing, the methods used to complete the testing, and similar, potential future work will be discussed.

  3. Sox7 is dispensable for primitive endoderm differentiation from mouse ES cells.

    Science.gov (United States)

    Kinoshita, Masaki; Shimosato, Daisuke; Yamane, Mariko; Niwa, Hitoshi

    2015-10-16

    Primitive endoderm is a cell lineage segregated from the epiblast in the blastocyst and gives rise to parietal and visceral endoderm. Sox7 is a member of the SoxF gene family that is specifically expressed in primitive endoderm in the late blastocyst, although its function in this cell lineage remains unclear. Here we characterize the function of Sox7 in primitive endoderm differentiation using mouse embryonic stem (ES) cells as a model system. We show that ectopic expression of Sox7 in ES cells has a marginal effect on triggering differentiation into primitive endoderm-like cells. We also show that targeted disruption of Sox7 in ES cells does not affect differentiation into primitive endoderm cells in embryoid body formation as well as by forced expression of Gata6. These data indicate that Sox7 function is supplementary and not essential for this differentiation from ES cells.

    Pluripotent stem cells, i.e., embryonic stem (ES) and induced pluripotent stem (iPS) cells, can indefinitely proliferate without commitment and differentiate into all cell lineages. ES cells are derived from the inner cell mass of the preimplantation blastocyst, whereas iPS cells are generated from somatic cells by overexpression of a few transcription factors. Many studies have demonstrated that mouse and human iPS cells are highly similar but not identical to their respective ES cell counterparts. The potential to generate basically any differentiated cell types from these cells offers the possibility to establish new models of mammalian development and to create new sources of cells for regenerative medicine. ES cells and iPS cells also provide useful models to study connexin expression and gap-junctional intercellular communication (GJIC) during cell differentiation and reprogramming. In 1996, we reported connexin expression and GJIC in mouse ES cells. Because a substantial number of papers on these subjects have been published since our report, this Mini Review summarizes currently available data on connexin expression and GJIC in ES cells and iPS cells during undifferentiated state, differentiation, and reprogramming.

  6. Regulation of Pax6 by CTCF during induction of mouse ES cell differentiation.

    Directory of Open Access Journals (Sweden)

    Jie Gao

    Full Text Available Pax6 plays an important role in embryonic cell (ES differentiation during embryonic development. Expression of Pax6 undergoes from a low level to high levels following ES cell differentiation to neural stem cells, and then fades away in most of the differentiated cell types. There is a limited knowledge concerning how Pax6 is regulated in ES cell differentiation. We report that Pax6 expression in mouse ES cells was controlled by CCCTC binding factor (CTCF through a promoter repression mechanism. Pax6 expression was significantly enhanced while CTCF activity was kept in the constant during ES cell differentiation to radial glial cells. Instead, the interaction of CTCF with Pax6 gene was regulated by decreased CTCF occupancy in its binding motifs upstream from Pax6 P0 promoter following the course of ES cell differentiation. Reduced occupancy of CTCF in the binding motif region upstream from the P0 promoter was due to increased DNA methylations in the CpG sites identified in the region. Furthermore, changes in DNA methylation levels in vitro and in vivo effectively altered methylation status of these identified CpG sites, which affected ability of CTCF to interact with the P0 promoter, resulting in increases in Pax6 expression. We conclude that there is an epigenetic mechanism involving regulations of Pax6 gene during ES cell differentiation to neural stem cells, which is through increases or decreases in methylation levels of Pax6 gene to effectively alter the ability of CTCF in control of Pax6 expression, respectively.

  7. AR Variant ARv567es Induces Carcinogenesis in a Novel Transgenic Mouse Model of Prostate Cancer

    2013-09-01

    Full Text Available Androgen deprivation therapy remains the primary treatment modality for patients with metastatic prostate cancer but is uniformly marked by progression to castration-resistant prostate cancer (CRPC after a period of regression. Continued activation of androgen receptor (AR signaling is attributed as one of the most important mechanisms underlying failure of therapy. Recently, the discovery of constitutively active AR splice variants (AR-Vs adds more credence to this idea. Expression of AR-Vs in metastases portends a rapid progression of the tumor. However, the precise role of the AR-Vs in CRPC still remains unknown. ARv567es is one of the two AR variants frequently found in human CRPC xenografts and metastases. Herein, we developed a probasin (Pb promoter-driven ARv567es transgenic mouse, Pb-ARv567es, to evaluate the role of ARv567es in both autonomous prostate growth and progression to CRPC. We found that expression of ARv567es in the prostate results in epithelial hyperplasia by 16 weeks and invasive adenocarcinoma is evident by 1 year of age. The underlying genetic cellular events involved a cell cycle-related transcriptome and differential expression of a spectrum of genes that are critical for tumor initiation and progression. These findings indicate that ARv567es could induce tumorigenesis de novo and signifies the critical role of AR-Vs in CRPC. Thus, the Pb-ARv567es mouse could provide a novel model in which the role of AR variants in prostate cancer progression can be examined.

    We observed nine primary transits of the hot Jpiter TrES-3b in several optical and near-UV photometric bands from 2009 June to 2012 April in an attempt to detect its magnetic field. Vidotto, Jardine and Helling suggest that the magnetic field of TrES-3b can be constrained if its near-UV light curve shows an early ingress compared to its optical light curve, while its egress remains unaffected. Predicted magnetic field strengths of Jpiter-like planets should range between 8 G and 30 G. Using these magnetic field values and an assumed B* of 100 G, the Vidotto et al. method predicts a timing difference of 5-11 min. We did not detect an early ingress in our three nights of near-UV observations, despite an average cadence of 68 s and an average photometric precision of 3.7 mmag. However, we determined an upper limit of TrES-3b's magnetic field strength to range between 0.013 and 1.3 G (for a 1-100 G magnetic field strength range for the host star, TrES-3) using a timing difference of 138 s derived from the Nyquist-Shannon sampling theorem. To verify our results of an abnormally small magnetic field strength for TrES-3b and to further constrain the techniques of Vidotto et al., we propose future observations of TrES-3b with other platforms capable of achieving a shorter near-UV cadence. We also present a refinement of the physical parameters of TrES-3b, an updated ephemeris and its first published near-UV light curve. We find that the near-UV planetary radius of Rp = 1.386+ 0.248- 0.144 RJup is consistent with the planet's optical radius.

    Full Text Available Resumen: La pregunta por la logicidad busca los criterios que hacen que cierto objeto se pueda considerar un objeto lógico. Los diferentes criterios de logicidad posibles marcarán no solo las distintas formas de concebir la lógica como disciplina académica, sino también distintos modos de entender, en el lenguaje ordinario o en otras disciplinas, qué quiere decir que algo es o no lógico. Mostramos que las aportaciones de las lógicas no clásicas y la pragmática, así como del estudio de otras formas de inferencia distintas de la deducción, enriquecen la caracterización intuitiva de la lógica, lo cual resulta de un interés especial cuando se trata de aplicar la lógica al entrenamiento y evaluación del razonamiento humano.Abstract: The question of logicality searches for criteria that make that a given object can be considered a logical object. Different criteria of logicality establish not only the different possible ways of conceiving logic as an academic discipline, but also the different ways of understanding, in natural language or in other disciplines, what means that something is logical or not. We show that the contribution of non-classical logics and pragmatics, and the study of other kinds of inference different to deduction, enrich the intuitive characterization of logic, which is of particular interest when trying to apply the logic for training and evaluating human reasoning.

  14. Mast Cell Subsets and Their Functional Modulation by the Acanthocheilonema viteae Product ES-62

    Full Text Available ES-62, an immunomodulator secreted by filarial nematodes, exhibits therapeutic potential in mouse models of allergic inflammation, at least in part by inducing the desensitisation of FcεRI-mediated mast cell responses. However, in addition to their pathogenic roles in allergic and autoimmune diseases, mast cells are important in fighting infection, wound healing, and resolving inflammation, reflecting that mast cells exhibit a phenotypic and functional plasticity. We have therefore characterised the differential functional responses to antigen (via FcεRI and LPS and their modulation by ES-62 of the mature peritoneal-derived mast cells (PDMC; serosal and those of the connective tissue-like mast cells (CTMC and the mucosal-like mast cells derived from bone marrow progenitors (BMMC as a first step to produce disease tissue-targeted therapeutics based on ES-62 action. All three mast cell populations were rendered hyporesponsive by ES-62 and whilst the mechanisms underlying such desensitisation have not been fully delineated, they reflect a downregulation of calcium and PKCα signalling. ES-62 also downregulated MyD88 and PKCδ in mucosal-type BMMC but not PDMC, the additional signals targeted in mucosal-type BMMC likely reflecting that these cells respond to antigen and LPS by degranulation and cytokine secretion whereas PDMC predominantly respond in a degranulation-based manner.

  15. Searching for a placental derived ES-62-like molecule to explain rheumatoid arthritis amelioration in pregnancy

    Craig D. Scoville

    2014-11-01

    Full Text Available The majority of women with rheumatoid arthritis (RA experience disease amelioration during pregnancy for unclear reasons. One possible explanation pursued and described here is whether the placenta produces a protein similar to the immunomodulating protein, ES-62, excreted by filarial nematodes. This protein has also been shown to reduce disease activity in animal models of RA. Eleven human placentas were prepared and a polyclonal anti-ES-62 antiserum was used to identify if any ES-62-like molecule exists from human placental tissues. Any bands identified were then excised from the gel and sent for mass spectrometry and protein identification. The anti-serum showed consistent cross reactivity with the heavy chain from immunoglobulin G (IgG from the eleven human placentas by mass spectrometry. No primary sequence homology between the heavy chain of IgG and ES-62 was identified. The placenta does not produce an ES-62-like molecule. However the binding of the antiserum to the Fc region of IgG suggests that this may be a possible mechanism for rheumatoid factor production in some patients with chronic filarial infections.

    2013-01-01

    Full Text Available This paper based on a fast implemented multiphase screen method using DFT puts forward an ionospheric Es layer clutter model and uses the newly developed dimensionality reduction space-time adaptive processing- (STAP- JDL algorithm to suppress Es layer clutter, which proves the validity of the proposed model. Firstly, the multiphase screen method was analyzed, and a fast algorithm using DFT was proposed. Then, based on the multiphase screen method and thorough simulation, we reached a conclusion of the high-frequency radio wave propagation’s fluctuation characteristics in the ionosphere. According to the results of the analysis, a new Es layer ionospheric clutter model was established and was compared with the measured data and verification was made. Finally, based on the built clutter model, JDL algorithm was applied to the high-frequency surface wave radar ionospheric clutter suppression, using the measured data to verify the validity of the model and algorithm. The simulation results showed that the built model can show the characteristics of the ionospheric Es layer clutter and that the JDL algorithm can suppress ionospheric Es layer clutter quite effectively.

    Inflammatory bowel disease (IBD) in developed countries is linked with elevated hygienic standards. One of the several factors involved in this question may be reduced exposure to the immunomodulatory effects of parasitic helminths. Several investigations on treatment of mice and humans with helminth-derived substances have supported this notion, but underlying mechanisms remain unclear. This study therefore dissects to what extent a series of immune-related genes are modulated in zebrafish with experimentally induced colitis following exposure to excretory-secretory (ES) products isolated from larval Anisakis, a widely distributed fish nematode. Adult zebrafish intrarectally exposed to the colitis-inducing agent TNBS developed severe colitis leading to 80% severe morbidity, but if co-injected (ip) with Anisakis ES products, the morbidity rate was 50% at the end of the experiment (48 hours post-exposure). Gene expression studies of TNBS-treated zebrafish showed clear upregulation of a range of genes encoding inflammatory cytokines and effector molecules and some induction of genes related to the adaptive response. A distinct innate-driven immune response was seen in both TNBS and TNBS + ES groups, but expression values were significantly depressed for several important pro-inflammatory genes in the TNBS + ES group, indicating protective mechanisms of Anisakis ES compounds on intestinal immunopathology in zebrafish. © 2017 John Wiley & Sons Ltd.

    Full Text Available Chaperonin GroEL (Cpn60 requires cofactor GroES (Cpn10 for protein refolding in bacteria that possess single groEL and groES genes in a bicistronic groESL operon. Among 4,861 completely-sequenced prokaryotic genomes, 884 possess duplicate groEL genes and 770 possess groEL genes with no neighboring groES. It is unclear whether stand-alone groEL requires groES in order to function and, if required, how duplicate groEL genes and unequal groES genes balance their expressions. In Myxococcus xanthus DK1622, we determined that, while duplicate groELs were alternatively deletable, the single groES that clusters with groEL1 was essential for cell survival. Either GroEL1 or GroEL2 required interactions with GroES for in vitro and in vivo functions. Deletion of groEL1 or groEL2 resulted in decreased expressions of both groEL and groES; and ectopic complementation of groEL recovered not only the groEL but also groES expressions. The addition of an extra groES gene upstream groEL2 to form a bicistronic operon had almost no influence on groES expression and the cell survival rate, whereas over-expression of groES using a self-replicating plasmid simultaneously increased the groEL expressions. The results indicated that M. xanthus DK1622 cells coordinate expressions of the duplicate groEL and single groES genes for synergistic functions of GroELs and GroES. We proposed a potential regulation mechanism for the expression coordination.

    Curved DNA structures with a left-handed superhelical conformation can activate eukaryotic transcription. However, their potency in transgene activation in embryonic stem (ES) cells has not been examined. T20 is an artificial curved DNA of 180 bp that serves as a transcriptional activator. We investigated the effect of T20 on transcription in mouse ES cell lines or hepatocytes differentiated from them. We established 10 sets of cell lines each harboring a single copy of the reporter construct. Each set comprised a T20-harboring cell line and a T20-less control cell line. Analyses showed that in ES cells and in hepatocytes originating from these cells, T20 both activated and repressed transcription in a manner that was dependent on the locus of reporter. The present and previous studies strongly suggest that in cells that have a strict gene regulation system, transcriptional activation by T20 occurs only in a transcriptionally active locus in the genome.

    In order to further promote integrated optimization operation of distributed new energy/ energy storage/ active load, this paper studies the integrated photovoltaic-energy storage (PV-ES) system which is connected with the distribution network, and analyzes typical structure and configuration selection for integrated PV-ES generation system. By combining practical grid- connected characteristics requirements and technology standard specification of photovoltaic generation system, this paper takes full account of energy storage system, and then proposes several new grid-connected performance indexes such as paralleled current sharing characteristic, parallel response consistency, adjusting characteristic, virtual moment of inertia characteristic, on- grid/off-grid switch characteristic, and so on. A comprehensive and feasible grid-connected performance index system is then established to support grid-connected performance testing on integrated PV-ES system.

    Full Text Available This study aims at using spatial data to investigate and analyze the temporal spatial growth of the city of Dar es Salaam in Tanzania and quantify its relationship to transportation growth. The study will focus on the period from 1945 to 2012 and will use population and economic growth as parameters. The findings of this study show that there is a mutual relationship between Dar es Salaam’s urban growth, population, economy, and transportation. It found that transportation demand and infrastructure growth coincided with population growth; however, Dar es Salaam’s urban spatial expansion and residential area growth have been affected by transportation demand and infrastructure growth. It also found that enormous spatial expansion has caused dramatic changes in the daily share of travel modes and that these disparities have occurred in relation to urban growth and transport. Development initiatives and policies over time have not successfully solved this problem.

    Glutamate synthase (GOGAT) is a key enzyme for nitrogen metabolism and ammonium assimilation in plants. In this study, an early senescence 7 (es7) mutant was identified and characterized. The leaves of the es7 mutant begin to senesce at the tillering stage about 60day after sowing, and become increasingly senescent as the plants develop at the heading stage. When es7 plants are grown under photorespiration-suppressed conditions (high CO2), the senescence phenotype and chlorophyll content are rescued. qRT-PCR analysis showed that senescence- associated genes were up-regulated significantly in es7. A map-based cloning strategy was used to identify ES7, which encodes a ferredoxin-dependent glutamate synthase (Fd-GOGAT). ES7 was expressed constitutively, and the ES7 protein was localized in chloroplast. qRT-PCR analysis indicated that several genes related to nitrogen metabolism were differentially expressed in es7. Further, we also demonstrated that chlorophyll synthesis-associated genes were significantly down-regulated in es7. In addition, when seedlings are grown under increasing nitrogen concentrations (NH4NO3) for 15days, the contents of chlorophyll a, chlorophyll b and total chlorophyll were significantly lower in es7. Our results demonstrated that ES7 is involved in nitrogen metabolism, effects chlorophyll synthesis, and may also associated with photorespiration, impacting leaf senescence in rice.

    Full Text Available BACKGROUND: Gene targeting (GT provides a powerful tool for the generation of precise genetic alterations in embryonic stem (ES cells to elucidate gene function and create animal models for human diseases. This technology has, however, been limited to mouse and rat. We have previously established ES cell lines and procedures for gene transfer and selection for homologous recombination (HR events in the fish medaka (Oryzias latipes. METHODOLOGY AND PRINCIPAL FINDINGS: Here we report HR-mediated GT in this organism. We designed a GT vector to disrupt the tumor suppressor gene p53 (also known as tp53. We show that all the three medaka ES cell lines, MES1∼MES3, are highly proficient for HR, as they produced detectable HR without drug selection. Furthermore, the positive-negative selection (PNS procedure enhanced HR by ∼12 folds. Out of 39 PNS-resistant colonies analyzed, 19 (48.7% were positive for GT by PCR genotyping. When 11 of the PCR-positive colonies were further analyzed, 6 (54.5% were found to be bona fide homologous recombinants by Southern blot analysis, sequencing and fluorescent in situ hybridization. This produces a high efficiency of up to 26.6% for p53 GT under PNS conditions. We show that p53 disruption and long-term propagation under drug selection conditions do not compromise the pluripotency, as p53-targeted ES cells retained stable growth, undifferentiated phenotype, pluripotency gene expression profile and differentiation potential in vitro and in vivo. CONCLUSIONS: Our results demonstrate that medaka ES cells are proficient for HR-mediated GT, offering a first model organism of lower vertebrates towards the development of full ES cell-based GT technology.

    ¿Cuándo es eficaz el terrorismo? El debate sobre la eficacia del terrorismo se ha centrado casi exclusivamente en los cambios que este fenómeno produce en la política estatal; no obstante, ello rara vez es el principal objetivo o el impacto más significativo de esta táctica. Este artículo presenta un marco analítico multinivel para examinar la eficacia del terrorismo, el cual incluye los tres tipos de efectividad que forman parte explícita de su definición: el uso de la violencia y la ...

    L'utilisation des eaux usées en pisciculture nécessite un traitement minimum indispensable (lagunage, épuration classique, prédilution, dilution simultanée). Une deuxième condition, non moins importante, est la sélection exclusive des eaux usées domestiques et rurales afin d'éviter la présence de métaux lourds et autres substances toxiques des rejets industriels. Dans un tel milieu enrichi, la production piscicole peut être doublée et même triplée sans nourriture additionnelle. Cependant, mêm...

    Analizo dos maneras de concebir la relación entre emociones y moral. La primera concibe el sentido moral como expresión de sentimientos morales. La segunda enfatiza que las convicciones morales pueden controlar nuestras emociones, y que es posible justificar estados emocionales. Aunque la motivación moral no tiene que ser racional, es posible la elección moral fundada en la coherencia interna de nuestras conviccionjes sobre la clase de persona que queremos ser y de las motivaciones adecuadas....

    Un genero centenario ya en otras tradiciones lexicográficas pero de corta vida en el ámbito hispánico es el de la lexicografía monolingüe para usuarios extranjeros. Tan breve es nuestra historia que a mí mismo me cupo la misíon de poner en evidencia Ia notable laguna existente y exponer el modelo del que se suponia debía de ser ese diccionario tan ausente como demandado. Aunque se habían publicado algunas obras que sin ser propiamente diccionarios para estudiantes extranjeros se anunciaban co...
