    In this work the AZCATL-PBC system based on a technique of ants colonies for the search of control rods patterns of those reactors of the Nuclear Power station of Laguna Verde (CNLV) is presented. The technique was applied to a transition cycle and one of balance. For both cycles they were compared the k{sub ef} values obtained with a Haling calculation and the control rods pattern proposed by AZCATL-PBC for a burnt one fixed. It was found that the methodology is able to extend the length of the cycle with respect to the Haling prediction, maintaining sure to the reactor. (Author)

  10. Una herencia conflictiva: El imaginario religioso colonial y la construcción de identidades nacionales

    Directory of Open Access Journals (Sweden)

    Alejandra Cebrelli

    2000-01-01

    Full Text Available Estos apuntes, elaborados desde los estudios literarios y culturales latinoamericanistas, proponen una reflexión sobre la formación de las identidades nacionales en Argentina y en Perú. Con tal fin, se realiza una lectura sociocrítica y contrastiva de dos comentarios del proceso por herejía al fue sometida Angela Carranza por el Santo Oficio de Lima a finales del siglo XVII, escritos casi dos centurias más tarde por Juan María Gutiérrez y por Ricardo Palma, respectivamente. La perspectiva metodológica elegida posibilita la aprehensión de algunos de los mecanismos mediante los cuales cada sociedad reelabora su pasado colonial y funda un patrimonio nacional con rasgos distintivos. Asimismo, pone en evidencia que la nación resulta un artificio geopolítico construido sobre regiones ?vividas? que la exceden desde el punto de vista temporal y que, más allá de los modelos culturales en boga, las memorias locales constituyen un anclaje identitario imposible de eludir.

    servizi prestati e degli investimenti effettuati, fossero inadeguati. E che, quindi, in questo ambito si operasse prestando scarsa attenzione a una valutazione costi/benefici degli investimenti sostenuti, che pure si andavano facendo di dimensioni rilevanti. Un ruolo importante e crescente viene oggi affidato alla pianificazione dei sistemi informativi che annualmente la P.A. deve effettuare. Quando si parla di piano per i sistemi informativi ci si riferisce a un piano di medio-lungo termine, in riferimento e in coerenza al quale possano essere orientate, effettuate e controllate, nel corso del tempo, le scelte delle singole Amministrazioni o Enti Pubblici. Nel lavoro che segue si e` partiti dall`analisi della situazione italiana, che prevede l`utilizzo di una specifica metodologia prodotta dall`AIPA per la pianificazione dei sistemi informativi nella Pubblica Amministrazione. la parte innovativa e sperimentale della tesi e` volta all`adeguamento di tale metodologia ad una realta` quale e` l`ENEA, diversa ad esempio da quella di un Ministero (per la quale la proposta AIPA e` ottimale), sia perche` cambiano i fini istituzionali e le conseguenti modalita` di gestione, sia perche` l`Ente e` caratterizzato da un forte decentramento e sia soprattutto perche e` mancata un`indagine conoscitiva dei vari processi di servizio, preliminare all`applicazione della proposta AIPA.

    In the frame of the experimental infrastructure development of the Reservoirs Laboratory of the Geothermal Department of the Instituto de Investigaciones Electricas (IIE), a methodology that allows the simultaneous determination of the thermal conductivity, thermal diffusivity and specific heat in rock samples and other solid materials of low and medium conductivity, was implemented. The methodology is based in the theoretical solution of temperature distribution around an ideal linear heat source immersed in an infinite medium. The three properties are derived from one relatively simple experiment, that essentially consists in recording the temporary temperature variation in a given point of the specimen during a short heating period. This methodology has special application in the geothermal area, as well as in other areas related to the development and exploitation of underground energy and mineral resources. [Espanol] En el marco de las actividades de desarrollo de infraestructura experimental del Laboratorio de Yacimientos del Departamento de Geotermia del Instituto de Investigaciones Electricas (IIE), se implemento una metodologia que permite determinar simultaneamente la conductividad termica, la difusividad termica y el calor especifico en muestras de rocas y otros materiales solidos de conductividad baja e intermedia. La metodologia se basa en la solucion teorica de la distribucion de temperatura alrededor de una fuente lineal ideal de calor inmersa en un medio infinito. Las tres propiedades se derivan de un solo experimento relativamente simple, que consiste esencialmente en registrar la variacion temporal de la temperatura en un punto dado del especimen durante un corto periodo de calentamiento. Esta metodologia tiene especial aplicacion en el ambito de la geotermia, asi como en otras areas relacionadas con el desarrollo y aprovechamiento de los recursos energeticos y minerales del subsuelo.

    2010-01-01

    Full Text Available La carne vacuna en diversas ciudades de Hispanoamérica colonial formaba parte de la dieta básica de la población. Y desde la conformación de los primeros núcleos poblacionales, su provisión se encontraba mediada por el estanco, sistema de abastecimiento monopólico, cuyo principal objetivo era asegurar el eficiente suministro de alimentos a la ciudad. En el presente escrito procuraremos mostrar que el estanco no funcionaba aún desde sus inicios, de manera totalmente eficiente, sino que presentaba fisuras, las que desembocarán, de facto primero y luego, ya formalmente, desde mediados del XVIII, en el sistema de libre competencia. Precisamente, el mercado de abasto era parte de una estructura económica mayor que, sin duda, influía y se veía influida por él. Es por eso que consideramos la importancia de abordar, en este caso desde el ámbito institucional, las características de este mercado en una coyuntura histórica específica. Las fuentes con las que se trabajará serán fundamentalmente las Actas del Cabildo referidas al abasto colonial.

    Full Text Available Hacia 1760, la intensificación de la circulación mercantil en el sur de los dominios hispánicos en América, la instalación de nuevos grupos araucanos y las políticas defensivas desarrolladas por los funcionarios borbónicos condujeron a la articulación de la frontera sur del imperio, enlazando diversos territorios coloniales e indígenas desde el Atlántico al Pacífico. Es en este escenario que nos proponemos, a partir de una historia de vida, demostrar las oportunidades que se generaron para el desarrollo de estrategias de construcción de poder y ascenso social desde la frontera. Para ello, analizaremos las prácticas políticas y los mecanismos económicos que sustentaron la trayectoria social del español Diego Trillo, quien hacia fines de la década de 1750 se asentó en el norte de la jurisdicción del Cabildo porteño, fue pulpero y hacendado, Sargento Mayor de milicias y Alcalde de la Hermandad y logró una importante acumulación económica. En particular, nos interesa identificar las mutuas relaciones establecidas entre su estrategia y proceso de acumulación económica, ciertas formas de representación e identificación y el desempeño de funciones estatales en un contexto de frontera. Argumentaremos que su trayectoria social respondió tanto a cuestiones y estrategias individuales como a cambios y continuidades en las condiciones políticas, económicas y culturales presentes en el Río de la Plata del último período colonial.

    Full Text Available Nella ricostruzione post-sisma di Messina un compito che coinvolse immediatamente amministratori, professionisti e maestranze fu la ricerca di un tipo edilizio antisismico. Meno stringenti si ritennero, alla luce di una cultura termotecnica in fieri, i problemi di benessere ambientale che concezioni strutturali a telaio, con murature "armate o animate" a chiudere le maglie, avrebbero potuto produrre. Riportando quelle esperienze alla contemporaneità, governata da una crisi eco-sistemica, si è avviato un confronto fra valori storico-testimoniali e qualità energetico-ambientale riferito a un esempio emblematico,attraverso la conoscenza della storia della sua costruzione, un monitoraggio strumentale dei parametri fisico tecnici e un accertamento della percezione soggettiva dei fruitori degli ambienti oggetto dell’indagine.

    Full Text Available En el ámbito de los estudios de mercado, los precios constituyen los principales indicadores del comportamiento de la economía, aun los de Antiguo Régimen. El objetivo del presente trabajo es abordar el análisis de los precios de la carne vacuna de la ciudad de Buenos Aires colonial partiendo de la idea de que este mercado, al igual que los de las distintas ciudades hispanoamericanas, presentó a lo largo de la etapa colonial una regularidad predominante. Y aun cuando estuvo atravesado por situaciones críticas de escasez, estos factores no lograron modificar sustancialmente, desde una mirada de largo plazo, las características del mismo.

    Full Text Available Polistes ferreri Saussure, 1853 is a Neotropical paper wasp often found in anthropic environments. However, there is little information available on biological, ecological and behavioral interactions of this species under these environmental conditions. This study investigated the colony cycle, foundation strategy and nesting biology of this species. From March of 2000 to February of 2004, several colonies were studied in the municipal district of Juiz de Fora, in southeastern Brazil. The colony cycle events of P. ferreri are concentrated in specific periods of the year. The colonies are established principally by association of females, the latter is the foundation strategy that confers the greatest success. Nidification on manmade substrates seems common for the species. The peduncle of the nest is increased in width to support the weight of colony members. Likewise, cells are increased in height, in accordance with the size of the layers of meconium, allowing accommodation of the immature. It is suggested that, at least for post-emergent colonies of P. ferreri, the cost of nest construction is not a factor limiting the development of the colonies. Finally, the results also support the idea that the reuse of cells is an advantageous strategy because it saves costs related to the construction of new cells.Polistes ferreri Saussure, 1853 es una avispa de papel neotropical encontrada a menudo en ambientes antrópicos.

    Ignacio Almada Bay

    2007-01-01

    Full Text Available Proponemos una nueva interpretación del régimen colonial en la provincia de Sonora y en el norte de la de Sinaloa -entre los ríos Gila y Fuerte-, basados en el proceso de descomposición registrado por las misiones desde 1681, manifiesto en una sucesión de rebeliones interétnicas y en una acentuada movilidad espacial de su población. Estos procesos conducen a considerar que el énfasis puesto en la expulsión de los misioneros en 1767 es más bien una estrategia de victimización; también se arguye, que la coerción física y simbólica empleada por ellos es intrínseca a la naturaleza del régimen misional establecido en la región. Además, la capacidad de respuesta política de las sociedades indígenas es más compleja de lo que conceden los textos de los misioneros, recuperada luego de la caída demográfica y fortalecida a lo largo del siglo XVIII. Por su parte, la población civil y presidial en este espacio tenía una dinámica propia, no subordinada a los misioneros.

    1996-12-01

    Full Text Available Neste artigo, o método científico de Jean-Baptiste Lamarck é estudado sob o ponto de vista de seu discurso metodológico, bem como sob o ponto de vista de sua prática científica. Essa metodologia é comparada à preconizada por Condillac, assim como à dos "ideólogos" (idéologues grupo no qual se costuma incluir o próprio Lamarck. Mostra-se que o discurso metodológico de Lamarck assemelha-se ao dos ideólogos; no entanto, sua prática científica não se coaduna com esse enfoque. Em vez de seguir uma abordagem empirista, a obra de Lamarck se fundamenta em princípios metafísicos gerais sobre a natureza. Sob o ponto de vista dos ideólogos, seu trabalho deveria ser rejeitado - o que de fato ocorreu - como um mero sistema (système metafísico - no sentido pejorativo utilizado pelos seguidores de Condillac. No entanto, o presente artigo argumenta que esse é justamente um importante e inovador aspecto da obra de Lamarck, que permitiu a eclosão do evolucionismo moderno.

Pero en el ámbito universitario y en la administración de justicia se formó una amalgama de alto valor teórico compuesta por ideas de la Escuela de Salamanca y del Derecho Indiano. El núcleo de estas doctrinas proclamaba la igualdad de todos los seres humanos ante Dios y su participación en derechos similares, por un lado, y la legitimidad de la conquista del Nuevo Mundo de parte de los españoles, por otro. En la praxis estas creaciones teóricas no tuvieron efecto sobre el terrible trabajo forzado impuesto a los indígenas.

    Determination of electrical losses is one of the most important tasks for any enterprise dedicated to generation, transmission, transformation and/or distribution of electric energy. Any enterprise dedicated to these activities does continuously energy balances in order to estimate whole electrical losses of specific processes. However, it is necessary to classify the whole electrical losses into technical and non-technical losses. This paper presents a proposal for estimating technical and non-technical losses in an electrical power system. [Spanish] La determinacion de las perdidas de energia electrica es una de las labores mas importantes en cualquier empresa dedicada a la generacion, transmision, transformacion y/o distribucion de energia electrica. Es indudable que toda empresa dedicada a cualquiera de las actividades mencionadas anteriormente realiza periodicamente balances de energia que permiten estimar el valor de las perdidas totales de energia del proceso considerado. No obstante, para poder realizar un mejor analisis de la problematica de las perdidas de energia, es necesario separar el valor total de perdidas obtenido mediante un balance de energia, en perdidas tecnicas y perdidas no tecnicas. El presente trabajo presenta una propuesta para la estimacion de perdidas tecnicas y no tecnicas en un sistema electrico de potencia.

The proposed model includes the following steps: Relative weights assignation for each IEEE-62-1995 required test. Those relative weights are obtained from test results and standardized and experience based limits obtained by Comision Federal de Electricidad (CFE). Once the relative weights have been assigned, three states, green, yellow and red were defined. Each state was then ranked with a weight number (1, 2 or 3). Specific weights were assigned for each test included in the model. Test score assignation takes into account the product of the relative value and the specific weight of each test. Transformer risk assessment uses the total score obtained from the sum of the tests partial scores. Transformer risk assessment was then classified in three categories. Total score causes the system to issue maintenance or substitution recommendations. The described model will improve maintenance scheduling according the transformer risk assessment and it is fully applicable to the complete CFE power transformer population. Further, smart investment and substitution plans, can be easily obtained from the model, preventing catastrophic failures that may cause logistic and economical problems to the Mexican Power System operation. As an example, the results obtained from the model application to two transformer banks installed in a CFE hydroelectric power plant were discussed and analyzed.

    Full Text Available En este artículo se analiza la trayectoria secular de una gran estancia rioplatense entre el fin del orden colonial y el inicio de la década de 1870, intentando comprender los cambios en la gestión, sus motivaciones y su racionalidad, así como los distintos factores que restringieron o ampliaron las opciones de inversión. El resultado muestra una empresa racionalmente orientada y dirigida, que sin embargo, debió enfrentar desafíos muy fuertes para mantener su competitividad durante la compleja y larga construcción del capitalismo rural.This article aims to analyze the secular way of a great River Plate cattle ranch, between late colonial period and the beginnings of the 1870's, trying to understand management changes, their motivations and rationality, as well as the different factors which narrowed or enlarged investment options. Results show a rationally-oriented and managed company; which, anyway, faced strong challenges to enhance his competitiveness during a complex rural capitalism construction process.

    Full Text Available Este trabajo de carácter exploratorio constituye una primera aproximación al análisis de las experiencias y los sentidos del tiempo implicados en las representaciones del orden social, según lo han vivido y significado los vecinos y los funcionarios de gobierno en Indias durante el período colonial. Nos proponemos desarrollar un estudio comparativo de las  instituciones del cabildo y los juicios de residencia, basado en el examen de un conjunto de documentos  de gobierno y justicia relativos a la gobernación del Tucumán durante los siglos XVII y XVIII y organizado a partir de dos interrogantes centrales. Por un lado, interesa abordar cómo se configuraban  y articulaban dos experiencias del tiempo diversas -un tiempo local y cotidiano y, otro tiempo que denominamos regio y ritual-; y por otro lado, exploramos de qué manera el carácter tradicional y formalizado de las prácticas que los cabildantes y los participantes del juicio de residencia desarrollaban en los contextos institucionales, contribuía a construir una representación del orden social figurado de gran estabilidad y anclado en un tiempo de larga duración.Palabras clave: tiempo; ritual; cabildos; juicio de residencia; Tucumán colonialAbstractThis exploratory work constitutes an approach to the analysis of time experiences y meanings that were implies in social order representation according to the lives and perspectives of  the vecinos and government functionaries in Indias during the colonial period.

    Full Text Available Las hermandades y cofradías con fines religiosos fueron corporaciones que sirvieron como instrumento y vehículo para la consolidación del cristianismo y representaron un orden social vigente. Algunas de ellas se especializaron en el culto a la Virgen Madre de Dios. Las cofradías han tenido un rol social polivalente dentro del cual es posible vislumbrar dos grandes vías: una material (la construcción de un patrimonio cofradial y su administración y otra de un fuerte contenido espiritual (circulación de discursos y prácticas religiosas. También constituyeron espacios de sociabilidad, alianzas, definición de identidades grupales, apoyo material y solidaridad entre sus miembros. Para esta exposición hemos decidido analizar dos casos diversos de esas cofradías marianas coloniales: una establecida en un área rural (la Cofradía de Nuestra Señora del Santísimo Rosario, sita en la iglesia parroquial de la villa de Luján y otra urbana (la Hermandad de Nuestra Señora de los Dolores y Benditas Ánimas del Purgatorio, que funcionó en la iglesia catedral de la ciudad de Buenos Aires.

    Full Text Available The following article will aim at reconstructing an intellectual network of people interested in both astrology and cosmography in seventeenth-century New Spain. This study will trace a particular means of transmission and dissemination of knowledge, namely the exchange of books on astrology, in order to identify a network of astrologers and cosmographers who shared a similar educational background and who had similar motivations to get interested in the so-called occult sciences. By doing so, this research will reflect on the problem of disciplinary boundaries during the early modern-period, and on the question of transmission of knowledge in the Iberian World.//El presente artículo tiene como objeto de estudio dos campos del conocimiento que estuvieron estrechamente relacionados durante el período moderno: la astrología y la cosmografía. Al estudiar algunos casos inquisitoriales contra ciertos cosmógrafos en Filipinas, acusados de practicar astrología juidiciaria, pretende reconstruir una red intelectual de estudiosos que compartían una tradición educativa y perseguían intereses profesionales similares. En su intento por rastrear esta microcomunidad intelectual, el presente estudio subraya la importancia de la transmisión y circulación del conocimiento, tanto a un nivel abstracto como material, no sólo entre el reino español y sus colonias en el Nuevo Mundo, sino también al interior de las colonias mismas.

    Full Text Available Cet article a pour objectif de considérer la dimension transhistorique des discours qui entourent la discrimination positive en France afin de mettre l’accent sur les origines et continuités du phénomène. Il s’agira premièrement d’évoquer le rapport dialectique et contradictoire que cette pratique différentialiste entretient avec les principes universalistes et républicains de la France. Je montrerai par la suite que le colonialisme et l’esclavage constituent certains des fondements historiques de cette politique, pourtant relativement récente dans l’Hexagone. En dernière instance, cette problématique sera envisagée au prisme du concept de « reconnaissance » — dans son acception fanonienne — afin de proposer l’analyse selon laquelle la discrimination positive s’inscrit dans une dynamique — nullement anachronique — qui renforce et perpétue insidieusement l’hégémonie culturelle et sociale des élites traditionnelles.El propósito de este artículo consiste en considerar la dimensión transhistórica de los discursos acerca de la discriminación positiva en Francia con vistas a enfatizar los orígenes y continuidades del fenómeno. En primer lugar, aludiré a la relación dialéctica y contradictoria que dicha práctica diferencialista mantiene con los principios universalistas y republicanos de Francia. Luego mostraré que el colonialismo y la esclavitud constituyen algunos de los fundamentos históricos de esta política, relativamente reciente en este país. En última instancia, contemplaré esta cuestión a través del prisma del concepto de “reconocimiento” — en su acepción fanoniana — con el fin de proponer el análisis según el cual la discriminación positiva se inscribe en una dinámica — de ningún modo anacrónica — que refuerza y perpetúa insidiosamente la hegemonía cultural y social de las élites tradicionales.

    Espera-se que o educando ao final da educação básica, adquira uma compreensão atualizada das hipóteses, modelos e formas de investigação sobre a origem e evolução do Universo em que vive. O presente trabalho tem como principal objetivo compreender dentre três práticas pedagógicas adotadas no Ensino de Astronomia, na terceira série do Ensino Médio, da Escola Estadual Colônia dos Pescadores, qual melhor cumpre o papel de formação e aprendizagem para vida. A pesquisa preliminar foi através de um questionário onde o intuito foi diagnosticar o conhecimento já existente acerca do tema em questão. O questionário é composto de vinte questões dissertativas e objetivas, onde os educandos das três turmas envolvidas o responderam. Este trabalho utiliza as seguintes metodologias: a tradicional, onde o professor é um repassador de informações, fazendo uso exclusivo de lousa e giz; a segunda também de forma tradicional, porém com auxílio de multimídia para desenvolvimento das aulas e aterceira sob forma de seminários, elaborados e apresentados pelos educandos, no qual o educador faz apenas as intervenções necessárias. Ao final do trabalho os alunos responderão novamente o questionário inicial para diagnosticar dentre as três metodologias utilizadas qual apresentou melhor resultado. Os resultados preliminares obtidos, já podem ser observados e, dos 119 alunos entrevistados, as respostas obtidas são as mais diversas e evidenciam que a grande maioria nunca teve em sua vida escolar o tema Astronomia. Ao serem questionados se já haviam estudado Astronomia as respostas foram: turma A: sim 43%; turma B: sim: 21%; turma C: sim: 24%. Porém quando questionados a respeito do significado de Astronomia observou-se que: turma A: 100% de acertos; turma B: 64% acertos; turma C: 84% de acertos, demonstrando claramente a aprendizagem em diferentes esferas, não dependendo unicamente da escola. Até o presente momento, verificou-se que há interesse em

    Este trabajo de investigacion supone un modelo teorico de caracter aplicado, que proporciona la oportunidad de evaluar la produccion cientifica de los investigadores. Se encuadra dentro de la tradiccion de la estadistica aplicada y la sociologia del conocimiento. Atiende especialmente a dos conjuntos de temas de interes, por una parte, las caracteristicas principales que determinan el nivel y tipo de produccion academica producida por las unidades de investigacion y por los propios investigadores; por otra, la utilizacion que se hace de los metodos y tecnicas de investigacion puesto que de ello tambien depende el modo de produccion cientifica. Los puntos novedosos de esta tesis son: la medicion cuantitativa del objeto de estudio, la suma de los productos y las condiciones externas a la produccion del conocimiento mas otros elementos internos como las caracteristicas de los investigadores y la metodologia utilizada para desarrollar sus trabajos; y, finalmente, el uso de las nuevas tecnologias. El aprovechamiento de los recursos estadisticos y las fuentes de informacion secundarias se complementan con el diseno propio de una encuesta donde se implementa las caracteristicas descritas en un capitulo anterior sobre los metodos cientificos mas idoneos descritos en los principales manuales y articulos cientificos desde distintas disciplinas de conocimiento. Dicha encuesta ha sido desarrollada como un programa propio y en base a los mas innovadores usos de la tecnologia en la metodologia de encuestas.

    Full Text Available Este trabajo aporta una mirada alterna sobre la modificación cefálica artificial entre los mayas, concretamente utilizando las observaciones de los cronistas que aún la vieron en la época Colonial. Sin querer, ellas nos comunican motivaciones íntimamente vinculadas con el rol que una vez tuvo la costumbre cefálica dentro de la cosmovisión y la ritualidad cotidiana de los mayas prehispánicos; así, estos testimonios constituyen puntos de partida invaluables para comprender los motivos culturales profundos que el modelado cefálico satisfacía originalmente. Por último, contrastamos y discutimos la información de las fuentes conjuntamente con el registro craneológico en siete series coloniales del territorio cultural maya. Los resultados confirman que el modelado cefálico pronto pierde vigencia en los centros urbanos con mayor presencia europea al mismo tiempo que se observa su pervivencia en los espacios rurales y selváticos más aislados, como los paraderos remotos de la selva lacandona.This paper contributes an alternative view on artificial head shaping practices among the Maya, which we examine through the lens of those European chroniclers who still witnessed it as a living practice during the colonial era. Unwillingly, these sources testify longstanding cultural motivations for the ancient tradition of modifying infants' vaults, which appear intimately tied to prehispanic Maya worldviews and daily ritual practices. The recognition of these motives provides a valuable point of departure for understanding the deeply embedded cultural roles this head practice once played. The last part of the paper compares and discusses the information provided by the colonial sources jointly with the results obtained from a study of seven colonial skeletal series from the Maya area. Our results confirm that Maya head modeling quickly dwindled within the urban spheres, where the European dominion was most immediate, while surviving over the

This leaves foreign workers in an integration dilemma, as they are expected to suppress home-country values and identities in order to become accepted, while...... at the same time they always are bound to fail to become ‘Swedish’ because of the same foreign origins. Although Swedish culture – partly by distancing itself from having a colonial past – has successfully built up an image of openness, we argue that without acknowledging and confronting the role...... that European colonial history has played in the shaping of national identity, Swedish organizations (and organizations in other western countries not assumed to have a colonial history) will not be able to integrate their foreign employees successfully....

It is based on the proposals of the classic researchers such as: Olgyay, Givoni and Szokolay, but also in new contributions like those of Yeang. Nevertheless, it is about a methodology adapted to the specific requirements of teaching and research that are carried out in the Bioclimatic Design Laboratory of the Universidad Autonoma Metropolitana, Azcapotzalco Unit. What is presented here is a part of a very ample research project that intends to develop or to structure a design methodology that incorporates the environmental variables related to man and architecture: of course, with the objective of facilitating the designer work so that the final architectonic product has a more harmonic response to the environment, offers conditions of integral well- being to its occupants and be is efficient in the handling of the resources. It also looks for the definition of the necessary analysis, design and evaluation tools, necessary in order that the application of the methodology is clear, simple and can be carried out by any designer, even if he does not have a wide knowledge of bioclimatic design.

    Full Text Available ABSTRACT Pheromones are chemicals produced as liquids by specialised cells or glands and transmitted into the environment as liquids or gases. In contrary to hormones, which are excreted in organism and have effect exclusively on organism that produced them, pheromones are excreted outside organism and effect on different individuals of the same species. Pheromones mediate nearly all aspects of honeybee colony life including social defence, brood care, mating, orientation, foraging and reproduction. Pheromone investigation has high economic importance. With use of pheromones it is possible to manipulate with pest insects on crops or to direct honeybees during pollination on target plants.

    Full Text Available Projects are crucial for the success of the organizations. The projects produce products, services, environment, processes and new or improved organizations. Furthermore, the projects increase sales, improve the satisfaction level of the clients, reduce the costs, and better the hob environment and so forth. Through this research paper the benefits of adopting a methodology that serves as a guide for Project management is discussed in detail. The most relevant benefit for the organization would be to deliver the product based upon the client necessities and requirements. The most important issues are as follows. 1. The methodology for project management imlies a change in attitude. 2. The time dedicated for the implementation and training for this kind of work constitutes the key factor for the success or failure of the project. 3. To homogenize the terminology, the organizations will declare indicators for each job leader. 4. The communication among the organizational members are truly important.

  18. Food and Coloniality

    Directory of Open Access Journals (Sweden)

    Adolfo Albán Achinte

    2011-05-01

    Full Text Available The author tackles the alimentary dimension of life, as something that goes beyond the simple act of ingesting food to acquire nutrients, to concentrate on the cultural implications of eating. To eat is more than to feed oneself, for eating is never by itself a wholly innocent act; that is, eating is never completely stripped from the social relationships of those gathered around a table.From this perspective, the article examines coloniality in all its forms (of power, of knowledge and of being, and shows their function as mechanisms of both alimentary enunciation and classification, that are responsible of the gastronomic supplantation of produce and food from the New World with the goods and customs that were so dear to European settlers (not forgetting that the influx of products and seasonings went also in the other direction. The colonizing project included thus, besides its religious, political and administrative pretenses, a gastronomical element, to be found in the eagerness of the colonizers to reproduce the alimentary imprint of their homeland in the new found territories, at least as far as the circumstances and the climate allowed it. Among all the facets the production of knowledge can acquire, gastronomy has been poorly studied —not to say completely silenced— in its role as a token of cultural divides, in which a coloniality of flavors and palates has been carried out.

  19. Colony Dimorphism in Bradyrhizobium Strains

    Sylvester-Bradley, Rosemary; Thornton, Philip; Jones, Peter

    1988-01-01

    Ten isolates of Bradyrhizobium spp. which form two colony types were studied; the isolates originated from a range of legume species. The two colony types differed in the amount of gum formed or size or both, depending on the strain. Whole 7-day-old colonies of each type were subcultured to determine the proportion of cells which had changed to the other type. An iterative computerized procedure was used to determine the rate of switching per generation between the two types and to predict proportions reached at equilibrium for each strain. The predicted proportions of the wetter (more gummy) or larger colony type at equilibrium differed significantly between strains, ranging from 0.9999 (strain CIAT 2383) to 0.0216 (strain CIAT 2469), because some strains switched faster from dry to wet (or small to large) and others switched faster from wet to dry (or large to small). Predicted equilibrium was reached after about 140 generations in strain USDA 76. In all but one strain (CIAT 3030) the growth rate of the wetter colony type was greater than or similar to that of the drier type. The mean difference in generation time between the two colony types was 0.37 h. Doubling times calculated for either colony type after 7 days of growth on the agar surface ranged from 6.0 to 7.3 h. The formation of two persistent colony types by one strain (clonal or colony dimorphism) may be a common phenomenon among Bradyrhizobium strains. Images PMID:16347599

Primeiramente, são delineados os pressupostos básicos da ciência moderna e sua evolução para a concepção atual de ciência pós-moderna.

A Psicologia Analítica de C. G.Jung é apresentada a partir do conceito atual de paradigma, que compreende três elementos fundamentais &– ontologia, epistemologia e metodologia &–, articulados de forma consistente e coerente. Assim, o método é necessariamente resultante da ontologia e da epistemologia. Dessa forma, a partir das noções de totalidade, consciente e inconsciente coletivo e pessoal, o conhecimento decorre da possibilidade de acesso ao inconsciente pela via do símbolo. O método de investigação psicológica se dá pela apreensão dos símbolos e sua compreensão, que resulta do processamento simbólico realizado pelo pesquisador.

  9. Genetic diversity affects colony survivorship in commercial honey bee colonies

    2013-08-01

    Honey bee ( Apis mellifera) queens mate with unusually high numbers of males (average of approximately 12 drones), although there is much variation among queens. One main consequence of such extreme polyandry is an increased diversity of worker genotypes within a colony, which has been shown empirically to confer significant adaptive advantages that result in higher colony productivity and survival. Moreover, honey bees are the primary insect pollinators used in modern commercial production agriculture, and their populations have been in decline worldwide. Here, we compare the mating frequencies of queens, and therefore, intracolony genetic diversity, in three commercial beekeeping operations to determine how they correlate with various measures of colony health and productivity, particularly the likelihood of queen supersedure and colony survival in functional, intensively managed beehives. We found the average effective paternity frequency ( m e ) of this population of honey bee queens to be 13.6 ± 6.76, which was not significantly different between colonies that superseded their queen and those that did not. However, colonies that were less genetically diverse (headed by queens with m e ≤ 7.0) were 2.86 times more likely to die by the end of the study when compared to colonies that were more genetically diverse (headed by queens with m e > 7.0). The stark contrast in colony survival based on increased genetic diversity suggests that there are important tangible benefits of increased queen mating number in managed honey bees, although the exact mechanism(s) that govern these benefits have not been fully elucidated.

  11. Colonial Figures: Memories of Street Traders in the Colonial and Early Post-colonial Periods

    Directory of Open Access Journals (Sweden)

    Sheri Lynn Gibbings

    2012-12-01

    Full Text Available This article explores post-colonial memories about street traders among individuals who lived in the former colony of the Dutch East Indies. It argues that these narratives romanticize the relationship between Europeans and indigenous peoples. Street vendors are also used to differentiate between periods within colonial and post-colonial history. The nostalgic representation of interracial contact between Europeans and traders is contrasted with representations of other figures such as the Japanese and the nationalist. A recurring feature of these representations is the ability of Europeans to speak with street traders and imagine what they wanted and needed. The traders are remembered as a social type that transgressed politics and represented the neutrality of the economic sphere as a place for shared communication. The article concludes that the figure of the street vendor contributes to the nostalgic reinvention of the colony but is also used in narratives to differentiate between and mark changes across the colonial and post-colonial periods.

    The present work proposes a methodology for evaluating grounding systems in electrical substations from medium and high voltage, in order to diagnose the state of the elements of the grounding system and the corresponding electrical variables. The assessment methodology developed includes a visual inspection phase to the elements of the substation. Then, by performing measurements and data analysis, the electrical continuity between the components of the substation and the mesh ground is verified, the soil resistivity and resistance of the mesh. Also included in the methodology the calculation of the step and touch voltage of the substation, based on the criteria of the International IEEE standards. We study the case of the 115 kV Pirital Substation belonging to PDVSA Oriente Transmission Network. [Spanish] En el presente trabajo se plantea una metodologia para la evaluacion de sistemas de puesta a tierra en subestaciones electricas de media y alta tension, con la finalidad de diagnosticar el estado de los elementos que conforman dicho sistema y las variables electricas correspondientes.

  15. Psicologia Comunitária: teoria e metodologia

    Directory of Open Access Journals (Sweden)

    Arendt Ronald J. J.

    1997-01-01

    Full Text Available Este texto pretende analisar o caminho percorrido pelos psicólogos comunitários desde a emergência da "crise" da Psicologia Social. Naquele momento, a crítica incidia sobre o psicólogo social experimental empírico-analítico, em contraste com o psicólogo comunitário, atento às metodologias qualitativas. Se o primeiro estava convicto do objeto de sua disciplina, o segundo, sensível aos aspectos sociais, históricos, antropológicos e políticos do contexto, não tem clareza quanto a seu objeto de estudo. Dos pressupostos teóricos e metodológicos imbuídos nestas práticas sugerir-se-á um retorno a questões psicológicas, enriquecidas com os referenciais das ciências sociais, numa tentativa de melhor precisar o "olhar" do psicólogo.

  2. Qual metodologia para uma criminologia crítica?

    2017-11-01

    Full Text Available Este ensaio propõe uma abordagem teórico-metodológica que visa fornecer elementos para pensar uma metodologia possível para a criminologia crítica. Sem realizar a polarização « macro-micro » à qual participa a criminologia crítica, pretende-se observar e analisar duas posturas diferentes de pesquisa que utilizam a entrevista com juízes como método de coleta de dados: uma, que pretende arrancar a verdade dos atores, abordados em um processo de cunho investigativo, e, outra, que visa conhecer, numa perspectiva de cunho empático-indutivo, o ponto de vista desses atores diante de uma necessidade eventual de desvendamento de suas práticas. Realiza-se uma crítica ao que podemos chamar de “sociologia do descompasso” e seu projeto correcionalista. Desta maneira, mais do que simplesmente medir e corrigir os descompassos de uma atividade observada, situamos o pesquisador como alguém que pretende compreender o descompasso e entender como os atores lidam com as normas que orientam as suas ações, e, como esses atores as justificam. Destacam-se neste ensaio: o modo como se observa a intersubjetividade na entrevista, o tipo de relação que se pretende ter em um processo de pesquisa, e a própria capacidade reflexiva da sociologia (de observar a si mesma neste processo.

  7. Colonial and post-colonial aspects of Australian identity.

    Tranter, Bruce; Donoghue, Jed

    2007-06-01

    Since the 1988 Bicentennial and the 2001 centenary of federation celebrations colonial images have flourished in Australia, highlighting the roles of convicts and free settlers during early colonization. Old sites, such as Port Arthur have been re-invigorated, and in 2004 Tasmanians celebrated the bicentenary of 'white' settlement. However, social scientists have given little attention to the role of colonial and post-colonial figures and myths as aspects of Australian national identity. We seek to address this issue by examining how convicts, free settlers, bushrangers and ANZACs are associated with contemporary identity in Australia. We examine evidence from the 2003 Australian Survey of Social Attitudes and find that historical figures such as the ANZACs and post-World War II immigrants comprise important aspects of national identity. A substantial majority of Australians judged ANZACs to be important, countering recent claims of the 'demise of the digger'. Sporting heroes are also at the core of Australian identity. Colonial figures appear to be far less important, although views on national identity vary according to social location. In particular, left-wing, university educated, younger, postmaterialist Australians view convicts and bushrangers as relatively important, indicating the salience of the larrikin in Australian identity.

    Full Text Available RESUMOO objetivo do artigo é discutir as metodologias de pesquisas sobre redes de negócios que são utilizadas por autores brasileiros, a partir de uma amostra da produção científica do Congresso EnAnpad. A proposição orientadora, criada a partir de reflexões prévias, é que os pesquisadores brasileiros utilizam predominantemente metodologias clássicas de disjunção e redução do fenômeno, buscando relações causais estritas, com objetos de estudo que são os atores e que tal abordagem é um dos motivos de existirem poucos avanços teóricos nesse campo. Para atingir o objetivo, foi necessário buscar na literatura internacional sobre redes as convergências de afirmativas, que servem de base para as discussões. Entre elas destacam-se os fluxos como objeto de estudo e a dinâmica constante das redes, o que dificulta estabelecerem-se relações causais estritas. As convergências revelaram dois paradigmas; o paradigma racional econômico, com teorias sobre os custos de transação e estratégias de redes, e o paradigma social, com teorias sobre a sociedade em rede e as relações sociais determinando os processos e controles das relações técnicas da rede. Aceitando e tendo como base as premissas desses paradigmas, analisaram-se os artigos publicados no Congresso EnAnpad nos últimos dez anos e concluiu-se que a afirmativa se sustenta. Há dominância do paradigma racional econômico, com o uso de métodos clássicos de coleta e análise, com questionários e entrevistas sobre atitudes e percepções, buscando relações causais estritas e não se encontram benefícios, ou avanços teóricos. Entendemos que é possível trilhar outro caminho metodológico, que consideramos mais competente para captar o fenômeno de redes, a partir da teoria da sociedade em rede; dos princípios epistemológicos da teoria da complexidade, principalmente o princípio da não-disjunção, e com o uso dos métodos e técnicas decorrentes da abordagem

  17. Queen promiscuity lowers disease within honeybee colonies.

    Science.gov (United States)

    Seeley, Thomas D; Tarpy, David R

    2007-01-07

    Most species of social insects have singly mated queens, but in some species each queen mates with numerous males to create a colony with a genetically diverse worker force. The adaptive significance of polyandry by social insect queens remains an evolutionary puzzle. Using the honeybee (Apis mellifera), we tested the hypothesis that polyandry improves a colony's resistance to disease. We established colonies headed by queens that had been artificially inseminated by either one or 10 drones. Later, we inoculated these colonies with spores of Paenibacillus larvae, the bacterium that causes a highly virulent disease of honeybee larvae (American foulbrood). We found that, on average, colonies headed by multiple-drone inseminated queens had markedly lower disease intensity and higher colony strength at the end of the summer relative to colonies headed by single-drone inseminated queens. These findings support the hypothesis that polyandry by social insect queens is an adaptation to counter disease within their colonies.

    tareas mas afectada por esta situacion es la operacion de los sistemas electricos frente a la presencia de fallas, donde la primera labor a realizar por parte del personal de operacion de la red es la pronta ubicacion del lugar de falla dentro del sistema. En el presente trabajo se aborda el problema del diagnostico de ubicacion de fallas electricas en sistemas de potencia, desde la perspectiva de los operadores de los centros de control de energia de una empresa electrica. El objetivo de este trabajo de tesis es describir una metodologia de analisis de operacion de protecciones como base para el desarrollo de un sistema de diagnostico de ubicacion de fallas, que permita estimar los posibles lugares de falla dentro del sistema asi como una justificacion de la operacion de las protecciones ante un disturbio como apoyo a los operadores de los Centros de Control de Energia. La metodologia esta disenada para utilizar distintos tipos de informacion, discreta, continua y controles. Sin embargo, en el desarrollo de la presente etapa de la metodologia propuesta se hace uso exclusivamente de la informacion de tipo discreta de los estados de interruptores y operacion de relevadores, asi como de la conectividad de los elementos de la red. La metodologia de analisis consiste en determinar el grupo de elementos donde pudo haber ocurrido la falla, utilizando las zonas de cobertura de las protecciones asociadas a los interruptores operados. Posteriormente, estas alternativas de falla se ordenan en forma descendentes de posibilidad utilizando indices de clasificacion y analisis basados en logica difusa.

  4. Honeybee immunity and colony losses

    Directory of Open Access Journals (Sweden)

    F. Nazzi

    2014-10-01

    Full Text Available The decline of honeybee colonies and their eventual collapse is a widespread phenomenon in the Northern hemisphere of the globe, which severely limits the beekeeping industry. This dramatic event is associated with an enhanced impact of parasites and pathogens on honeybees, which is indicative of reduced immunocompetence. The parasitic mite Varroa destructor and the vectored viral pathogens appear to play a key-role in the induction of this complex syndrome. In particular, the Deformed Wing Virus (DWV is widespread and is now considered, along with Varroa, one of the major causes of bee colony losses. Several lines of evidence indicate that this mite/DWV association severely affects the immune system of honeybees and makes them more sensitive to the action of other stress factors. The molecular mechanisms underpinning these complex interactions are currently being investigated and the emerging information has allowed the development of a new functional model, describing how different stress factors may synergistically concur in the induction of bee immune alteration and health decline. This provides a new logical framework in which to interpret the proposed multifactorial origin of bee colony losses and sets the stage for a more comprehensive and integrated analysis of the effect that multiple stress agents may have on honeybees.

    Full Text Available This article looks at the contesting articulations of gender, family, and religion in colonial South India. The article discusses the encounter between matrilineal customs and the Anglo-Muhammadan law in the site of Mappila Muslim matrilineal practices in colonial Malabar, of the Madras Presidency during c. 1910-1928. Young male members of the joint family used the language that matriliny is un-Islamic, and passed laws in the Legislative Assembly to demand that joint family property requires to be inherited in the patrilineal line. Three legislations were passed during the period of 1910-1940 to bring Muslim families in accordance with the ideal notions of familial organization existed in that period. The ideal notions were set up by the precepts of the Anglo-Muhammadan law, the orientalist knowledge of Islam, ideologies of colonial modernity, and dreams of caste and religious reform movements among the people of Malabar, and other neighboring states, Cochin and Travancore. In response to that, there was a re-articulation of customs and familial practices by using legal provisions available in the Islamic law, and an effort for justifying the practices to avoid the ruin of matriliny. Subsequently, the matrilineal Mappilas of Malabar retained matrilineal customs rather intact, though the gender relations and religious practices were re-articulated in the idioms of patriarchy and textuality.

  7. Deadly competition between sibling bacterial colonies

    2011-03-01

    As a result of stress due to nutrient limitation or antibiotics, competing individual bacteria within a single colony may lyse sibling cells to release nutrients (cannibalism) or DNA (fratricide). However, we have recently shown that competition is not limited to individuals, but can occur at the colony level [A. Be'er et al., PNAS 106, 428 (2009); A. Be'er et al., PNAS 107, 6258 (2010).] In response to the presence of an encroaching sibling colony, Paenibacillus dendritiformis bacteria secrete a lethal protein, lysing cells at the interface between the colonies. Analysis of the proteins secreted by these competing sibling colonies, combined with a mathematical model, shows how colonies maintain their growth by self-regulating the secretion of two proteins: subtilisin (a well-known growth promoter), and Slf (a previously unknown protein, which is lethal). The results also explain why a single colony is not inhibited by its own secretions.

    A methodology to carry out Reliability Centered Maintenance (RCM) studies for hydroelectric power plants is presented. The methodology is an implantation/extension of the guidelines proposed by the Engineering Society for Advanced Mobility Land, Sea and Space in the SAE-JA1012 standard. With the purpose of answering the first five questions, that are set out in that standard, the use of standard ISO14224 is strongly recommended. This approach standardizes failure mechanisms and homogenizes RCM studies with the process of collecting failure and maintenance data. The use of risk matrixes to rank the importance of each failure based on a risk criteria is also proposed. [Spanish] Se presenta una metodologia para realizar estudios de mantenimiento Basado en Confiabilidad (RCM) aplicados a la industria hidroelectrica. La metodologia es una implantacion/ extension realizada por los autores de este trabajo, de los lineamientos propuestos por la Engineering Society for Advanced Mobility Land, Sea and Space en el estandar SAE-JA1012. Para contestar las primeras cinco preguntas del estandar se propone tomar como base los modos y mecanismos de fallas de componentes documentados en la guia para recopilar datos de falla en el estandar ISO-14224. Este enfoque permite estandarizar la descripcion de mecanismos de fallas de los equipos, tanto en el estudio RCM como en el proceso de recopilacion de datos de falla y de mantenimiento, lo que permite retroalimentar el ciclo de mejora continua de los procesos RCM. Tambien se propone el uso de matrices de riesgo para jerarquizar la importancia de los mecanismos de falla con base en el nivel de riesgo.

We explore affective politics and the role heritage can play in the landscape of body politics. We aim...... to shed light over why statues still matter and we argue that affective politics – defined as politics that engage bodies immediately – is due to site-specific actions capable of going viral but likewise to non-photogenic scenes with indexical power.

Strategies have included foregrounding the plurality of history to disrupt linear progress; positing non-Western centers of modernity in, say, Moscow or Shanghai; and tracing anticolonial circuits connecting Asia to Africa to Latin America. The two recent books under review here add colonial-era Korea to such far-reaching discussions by situating the country across national boundaries. Interestingly, one connecting thread here is the alternative world system provided by the interwar, Soviet-oriented Left. The result is an unsettling of binaries that subsequently became entrenched during the Cold War: for example, north-south, socialist-nationalist, and, for literature, realist-modernist. But more broadly, pervading both books is the sense that history could have turned out differently—that revisiting northeast Asia’s porous borders in the early twentieth century reveals the Korean peninsula’s lost, internationalist potential...

    Most species of social insects have singly mated queens, but in some species each queen mates with numerous males to create a colony with a genetically diverse worker force. The adaptive significance of polyandry by social insect queens remains an evolutionary puzzle. Using the honeybee (Apis mellifera), we tested the hypothesis that polyandry improves a colony's resistance to disease. We established colonies headed by queens that had been artificially inseminated by either one or 10 drones. ...

The project aims to evaluate the spatial distribution of basic primary services (such as pharmacies, doctors' offices and shops that sell all the basic necessities concerning people with reduced mobility, in order to provide cognitive tools in support of a land-use planning (managed by local authorities, which meets the needs of the resident population. We decided to consider the village of Tivoli. The city shows some service management issues, mainly due to the presence of two portions with reduced intermobility. As regards the analysis of population, starting from the sections of ISTAT data, we evaluated the distribution of the population characterized by reduced mobility in the different parts, related to the onset of chronic diseases in age groups above 60 years. This study aims to suggest local authorities to optimize the redistribution of the above-written services and to improve the accessibility for people with reduced mobility.

    Full Text Available Across the Northern hemisphere, managed honey bee colonies, Apis mellifera, are currently affected by abrupt depopulation during winter and many factors are suspected to be involved, either alone or in combination. Parasites and pathogens are considered as principal actors, in particular the ectoparasitic mite Varroa destructor, associated viruses and the microsporidian Nosema ceranae. Here we used long term monitoring of colonies and screening for eleven disease agents and genes involved in bee immunity and physiology to identify predictive markers of honeybee colony losses during winter. The data show that DWV, Nosema ceranae, Varroa destructor and Vitellogenin can be predictive markers for winter colony losses, but their predictive power strongly depends on the season. In particular, the data support that V. destructor is a key player for losses, arguably in line with its specific impact on the health of individual bees and colonies.

  17. Form and metabolic scaling in colonial animals.

    Science.gov (United States)

    Hartikainen, Hanna; Humphries, Stuart; Okamura, Beth

    2014-03-01

    Benthic colonial organisms exhibit a wide variation in size and shape and provide excellent model systems for testing the predictions of models that describe the scaling of metabolic rate with organism size. We tested the hypothesis that colony form will influence metabolic scaling and its derivatives by characterising metabolic and propagule production rates in three species of freshwater bryozoans that vary in morphology and module organisation and which demonstrate two- and three-dimensional growth forms. The results were evaluated with respect to predictions from two models for metabolic scaling. Isometric metabolic scaling in two-dimensional colonies supported predictions of a model based on dynamic energy budget theory (DEB) and not those of a model based on fractally branching supply networks. This metabolic isometry appears to be achieved by equivalent energy budgets of edge and central modules, in one species (Cristatella mucedo) via linear growth and in a second species (Lophopus crystallinus) by colony fission. Allometric scaling characterised colonies of a three-dimensional species (Fredericella sultana), also providing support for the DEB model. Isometric scaling of propagule production rates for C. mucedo and F. sultana suggests that the number of propagules produced in colonies increases in direct proportion with the number of modules within colonies. Feeding currents generated by bryozoans function in both food capture and respiration, thus linking metabolic scaling with dynamics of self-shading and resource capture. Metabolic rates fundamentally dictate organismal performance (e.g. growth, reproduction) and, as we show here, are linked with colony form. Metabolic profiles and associated variation in colony form should therefore influence the outcome of biotic interactions in habitats dominated by colonial animals and may drive patterns of macroevolution.

  18. Growth of bacteria in 3-d colonies.

    2017-07-01

    The dynamics of growth of bacterial populations has been extensively studied for planktonic cells in well-agitated liquid culture, in which all cells have equal access to nutrients. In the real world, bacteria are more likely to live in physically structured habitats as colonies, within which individual cells vary in their access to nutrients. The dynamics of bacterial growth in such conditions is poorly understood, and, unlike that for liquid culture, there is not a standard broadly used mathematical model for bacterial populations growing in colonies in three dimensions (3-d). By extending the classic Monod model of resource-limited population growth to allow for spatial heterogeneity in the bacterial access to nutrients, we develop a 3-d model of colonies, in which bacteria consume diffusing nutrients in their vicinity. By following the changes in density of E. coli in liquid and embedded in glucose-limited soft agar, we evaluate the fit of this model to experimental data. The model accounts for the experimentally observed presence of a sub-exponential, diffusion-limited growth regime in colonies, which is absent in liquid cultures. The model predicts and our experiments confirm that, as a consequence of inter-colony competition for the diffusing nutrients and of cell death, there is a non-monotonic relationship between total number of colonies within the habitat and the total number of individual cells in all of these colonies. This combined theoretical-experimental study reveals that, within 3-d colonies, E. coli cells are loosely packed, and colonies produce about 2.5 times as many cells as the liquid culture from the same amount of nutrients. We verify that this is because cells in liquid culture are larger than in colonies. Our model provides a baseline description of bacterial growth in 3-d, deviations from which can be used to identify phenotypic heterogeneities and inter-cellular interactions that further contribute to the structure of bacterial

This combined theoretical-experimental study reveals that, within 3-d colonies, E. coli cells are loosely packed, and colonies produce about 2.5 times as many cells as the liquid culture from the same amount of nutrients. We verify that this is because cells in liquid culture are larger than in colonies. Our model provides a baseline description of bacterial growth in 3-d, deviations from which can be used to identify phenotypic heterogeneities and inter-cellular interactions that further contribute to the structure of

    Swarming is a widespread phenomenon observed in both biological and non-biological systems. Large mammal herds, fish schools, and bird flocks are among the most spectacular examples. Many theoretical and numerical efforts have been made to unveil the general principles of the phenomenon, but systematic experimental studies have been very limited. We determine the characteristic velocity, length, and time scales for bacterial motion in swarming colonies of Paenibacillus dendritiformis growing on semi-solid agar substrates. The bacteria swim within a thin fluid layer, and they form long-lived jets and vortices. These coherent structures lead to anisotropy in velocity spatial correlations and to a two-step relaxation in velocity temporal correlations. The mean squared displacement of passive tracers exhibits a short-time regime with nearly ballistic transport and a diffusive long-time regime. We find that various definitions of the correlation length all lead to length scales that are, surprisingly, essentially independent of the mean bacterial speed, while the correlation time is linearly proportional to the ratio of the correlation length to the mean speed.

  1. Colony Foundation in an Oceanic Seabird

    Seabirds are colonial vertebrates that despite their great potential for long-range dispersal and colonization are reluctant to establish in novel locations, often recruiting close to their natal colony. The foundation of colonies is therefore a rare event in most seabird species and little is known about the colonization process in this group. The Cory’s shearwater (Calonectris diomedea) is a pelagic seabird that has recently established three new colonies in Galicia (NE Atlantic) thus expanding its distribution range 500 km northwards. This study aimed to describe the establishment and early progress of the new Galician populations and to determine the genetic and morphometric characteristics of the individuals participating in these foundation events. Using 10 microsatellite loci, we tested the predictions supported by different seabird colonization models. Possibly three groups of non-breeders, adding up to around 200 birds, started visiting the Galician colonies in the mid 2000’s and some of them eventually laid eggs and reproduced, thus establishing new breeding colonies. The Galician populations showed a high genetic diversity and a frequency of private alleles similar to or even higher than some of the large historical populations. Most individuals were assigned to several Atlantic populations and a few (if any) to Mediterranean colonies. Our study suggests that a large and admixed population is settling in Galicia, in agreement with predictions from island metapopulation models of colonization. Multiple source colonies imply that some birds colonizing Galicia were dispersing from very distant colonies (> 1500 km). Long-distance colonizations undertaken by relatively large and admixed groups of colonizers can help to explain the low levels of genetic structure over vast areas that are characteristic of most oceanic seabird species.

  2. Evolutional Ant Colony Method Using PSO

    Science.gov (United States)

    Morii, Nobuto; Aiyoshi, Eitarou

    The ant colony method is one of heuristic methods capable of solving the traveling salesman problem (TSP), in which a good tour is generated by the artificial ant's probabilistic behavior. However, the generated tour length depends on the parameter describing the ant's behavior, and the best parameters corresponding to the problem to be solved is unknown. In this technical note, the evolutional strategy is presented to find the best parameter of the ant colony by using Particle Swarm Optimization (PSO) in the parameter space. Numerical simulations for benchmarks demonstrate effectiveness of the evolutional ant colony method.

    la ocupación colonial. El trabajo explora cómo el lenguaje feudal en Dinesen extiende el género de lo pastoral europeo hacia el ámbito colonial para ponerlo en función de la búsqueda de un discurso de legitimidad. Sostengo que esta es una preocupación constante de la literatura colonial. Analizo en detalle la lógica reflexiva mediante la cual la narradora se enfrenta a África como un espacio que a una vez mima y rechaza el narcisismo psicopolítico del colono. Las memorias de Dinesen ponen en evidencia un sinnúmero de maquinaciones de carácter narcisista mediante las cuales la narradora intenta manejar el tándem enredado de la pregunta “¿Qué significa África para ti y tu qué eres para África?”

    In the gradual unravelling of Greenland’s colonial relationship to Denmark, an essentialist conceptualization of Greenlandic identity has played a significant role. However, both our scholarly understanding of post-colonial Greenlandic identity and the process towards independence for Greenland...... could be furthered by bringing politics back in. Based on a discourse analysis of the Greenlandic debate on language, this paper makes three claims: First, the identity projects promoted in Greenland are based on an essentialist conception of identity. Secondly, Greenlandic identity discourse combines...... elements of traditional Inuit culture and elements of colonial modernity. Thirdly, monolingual Greenlanders are those with the most to gain from abandoning the dichotomy of essentialist identities. Strategically, the paper suggests a post-post-colonial Greenlandic identity as a means of avoiding...

    Recent losses in honey bee colonies are unusual in their severity, geographical distribution, and, in some cases, failure to present recognized characteristics of known disease. Domesticated honey bees face numerous pests and pathogens, tempting hypotheses that colony collapses arise from exposure to new or resurgent pathogens. Here we explore the incidence and abundance of currently known honey bee pathogens in colonies suffering from Colony Collapse Disorder (CCD), otherwise weak colonies, and strong colonies from across the United States. Although pathogen identities differed between the eastern and western United States, there was a greater incidence and abundance of pathogens in CCD colonies. Pathogen loads were highly covariant in CCD but not control hives, suggesting that CCD colonies rapidly become susceptible to a diverse set of pathogens, or that co-infections can act synergistically to produce the rapid depletion of workers that characterizes the disorder. We also tested workers from a CCD-free apiary to confirm that significant positive correlations among pathogen loads can develop at the level of individual bees and not merely as a secondary effect of CCD. This observation and other recent data highlight pathogen interactions as important components of bee disease. Finally, we used deep RNA sequencing to further characterize microbial diversity in CCD and non-CCD hives. We identified novel strains of the recently described Lake Sinai viruses (LSV) and found evidence of a shift in gut bacterial composition that may be a biomarker of CCD. The results are discussed with respect to host-parasite interactions and other environmental stressors of honey bees. PMID:22927991

    Full Text Available OBJETIVO: comparar duas metodologias para o cálculo do volume placentário em gestações normais de termo: a do princípio de Arquimedes e a do volume do cilindro, para estimar a densidade absoluta da placenta. Definir a metodologia mais adequada para o cálculo do volume e densidade placentários, que se relacione com o peso e classificação do recém-nascido. MÉTODOS: foram estudadas 50 placentas provenientes de gestações de termo sem complicações e calculados o volume e a densidade absoluta placentários: a pelo princípio de Arquimedes e b na suposição de que a placenta seria uma secção de cilindro com duas alturas diferentes do bolo placentário: com a altura média e com a altura da média aritmética do centro e extremidades. As densidades absolutas placentárias foram calculadas pelo quociente entre o peso ao ar da placenta e os diferentes volumes. RESULTADOS: a maioria das gestantes eram multíparas, idade média de 25,4 anos, volume placentário médio entre 547,8 e 610 cmsuperscript three e densidade média entre 0,94 e 1,14 g/cmsuperscript three, dependendo da metodologia empregada. CONCLUSÕES: a metodologia mais adequada para estimar o volume placentário no termo foi a do princípio de Arquimedes, pela melhor correlação com o peso dos recém-nascidos, o índice placentário e a classificação do peso dos recém-nascidos em relação à idade gestacional.

El impacto de la conquista y colonización del Nuevo Mundo se encuentra estrechamente imbricado a la conformación de los sectores de convergencia que coadyuvaron a la transformación del espacio territorial y sociocultural, cuyas implicaciones son palpables a través de un dilatado transcurso del tiempo que incluso desemboca en los movimientos emancipadores y la conformación de los Estadosnacionales. El establecimiento de las instituciones hispanas en América fue una estrategia que la Corona implementó para cristalizar la sujeción de los territorios del Nuevo Mundo y darle cause a su política de utilidad económica. Pero más allá de los primeros contactos, el eje fundamental del sistema colonial giró en torno a la explotación minera, el trabajo compulsivo implementado en las repúblicas de indios y el producto de la mano de obra esclava. El contacto entre los componentes heterogéneos que intervinieron en dicho proceso, tanto de los sectores sociales dominantes compuestos por colonizadores y representantes de las instituciones hispanas, como también, de los grupos subalternos conformados por la población indígena y afrodescendiente, generó una serie de cambios en el entorno cultural que gradualmente fueron cobrando vigencia en el transcurso de los siglos. La colonización abrió un nuevo modelo de sujeción a través de pactos e instituciones que tenían la finalidad de mantener vigentes los mecanismos compulsivos inherentes a la condición de vasallaje que adquirieron las poblaciones originarias, como también, de establecer y preservar el nuevo ordenamiento sociopolítico implantado por los conquistadores.

  20. ColonyArea: an ImageJ plugin to automatically quantify colony formation in clonogenic assays.

    Directory of Open Access Journals (Sweden)

    Camilo Guzmán

    Full Text Available The clonogenic or colony formation assay is a widely used method to study the number and size of cancer cell colonies that remain after irradiation or cytotoxic agent administration and serves as a measure for the anti-proliferative effect of these treatments. Alternatively, this assay is used to quantitate the transforming potential of cancer associated genes and chemical agents. Therefore, there is a need for a simplified and standardized analysis of colony formation assays for both routine laboratory use and for parallelized automated analysis. Here we describe the freely available ImageJ-plugin "ColonyArea", which is optimized for rapid and quantitative analysis of focus formation assays conducted in 6- to 24-well dishes. ColonyArea processes image data of multi-well dishes, by separating, concentrically cropping and background correcting well images individually, before colony formation is quantitated. Instead of counting the number of colonies, ColonyArea determines the percentage of area covered by crystal violet stained cell colonies, also taking the intensity of the staining and therefore cell density into account. We demonstrate that these parameters alone or in combination allow for robust quantification of IC50 values of the cytotoxic effect of two staurosporines, UCN-01 and staurosporine (STS on human glioblastoma cells (T98G. The relation between the potencies of the two compounds compared very well with that obtained from an absorbance based method to quantify colony growth and to published data. The ColonyArea ImageJ plugin provides a simple and efficient analysis routine to quantitate assay data of one of the most commonly used cellular assays. The bundle is freely available for download as supporting information. We expect that ColonyArea will be of broad utility for cancer biologists, as well as clinical radiation scientists.

    Full Text Available Administrative corruption in Cuba during the nineteenth century was a serious problem addressed both by Spanish authorities and the critics of the colonial system in Cuba. In the long run the fiscal, financial, institutional, and ideological costs of corruption undermined Spanish colonial control in Cuba. While the state and Cuban taxpayers had to pay for the increased costs of corruption, corrupt public officials and private contractors and financiers benefited. This study uses both archival manuscript administrative sources and published sources to assess the impact of corruption and its institutional bases during the final phase of Spanish colonialism in Cuba and the early period of post-colonial transition.

    La corrupción administrativa en Cuba durante el siglo XIX constituyó un problema reconocido como muy grave tanto por las autoridades españolas como por los críticos del sistema colonial cubano. Los costos fiscales, institucionales, e ideológicos de la corrupción contribuían a la erosión del dominio español en Cuba. A causa de la corrupción el Estado percibía menos ingresos y los contribuyentes cubanos se veían forzados a llevar a cuestas una creciente deuda pública. Los funcionarios corruptos y los contratistas y financistas privilegiados por el rígido sistema colonial, por el contrario, percibían los beneficios informales a que se creían acreedores por defender el dominio territorial español en Cuba. Utilizando fuentes administrativas manuscritas de archivos cubanos y españoles, así como fuentes públicas impresas, este trabajo evalúa el impacto de la corrupción y sus particulares bases institucionales en la fase final del colonialismo español en la isla y la transición post-colonial temprana.

    One of the potential areas for energy saving in Central Electric Power Plants are the auxiliaries system, so as to based in a preliminary energy diagnosis and considering that energy saving measures would be taken, going from the instrumentation, operational changes in equipment, as well as in using velocity variators in motors, it turns out to be that the energy consumption of auxiliaries at 75% load in a 150 MW thermal power plant varies from 3% to 4% and for the case of a 350 MW power plant the energy consumption of the auxiliaries represents 2 to 3.5%. Nowadays this consumption are above 6%. Considering that the country has 40 units with capacities varying from 150 to 350 MW, the economical and the fuel saving would be substantial. This paper will present a summary of the methodology to be used to carry out this type of projects.

Hoy en dia dichos consumos estan por encima del 6%. Si consideramos que el pais cuenta con 40 unidades que varian desde 150 MW hasta 350 MW, entonces los ahorros economicos y de combustible serian impactantes.

  14. Colony formation in the cyanobacterium Microcystis.

    Xiao, Man; Li, Ming; Reynolds, Colin S

    2018-02-22

    Morphological evolution from a unicellular to multicellular state provides greater opportunities for organisms to attain larger and more complex living forms. As the most common freshwater cyanobacterial genus, Microcystis is a unicellular microorganism, with high phenotypic plasticity, which forms colonies and blooms in lakes and reservoirs worldwide. We conducted a systematic review of field studies from the 1990s to 2017 where Microcystis was dominant. Microcystis was detected as the dominant genus in waterbodies from temperate to subtropical and tropical zones. Unicellular Microcystis spp. can be induced to form colonies by adjusting biotic and abiotic factors in laboratory. Colony formation by cell division has been induced by zooplankton filtrate, high Pb 2+ concentration, the presence of another cyanobacterium (Cylindrospermopsis raciborskii), heterotrophic bacteria, and by low temperature and light intensity. Colony formation by cell adhesion can be induced by zooplankton grazing, high Ca 2+ concentration, and microcystins. We hypothesise that single cells of all Microcystis morphospecies initially form colonies with a similar morphology to those found in the early spring. These colonies gradually change their morphology to that of M. ichthyoblabe, M. wesenbergii and M. aeruginosa with changing environmental conditions. Colony formation provides Microcystis with many ecological advantages, including adaption to varying light, sustained growth under poor nutrient supply, protection from chemical stressors and protection from grazing. These benefits represent passive tactics responding to environmental stress. Microcystis colonies form at the cost of decreased specific growth rates compared with a unicellular habit. Large colony size allows Microcystis to attain rapid floating velocities (maximum recorded for a single colony, ∼ 10.08 m h -1 ) that enable them to develop and maintain a large biomass near the surface of eutrophic lakes, where they may shade

    Background Over the last two winters, there have been large-scale, unexplained losses of managed honey bee (Apis mellifera L.) colonies in the United States. In the absence of a known cause, this syndrome was named Colony Collapse Disorder (CCD) because the main trait was a rapid loss of adult worker bees. We initiated a descriptive epizootiological study in order to better characterize CCD and compare risk factor exposure between populations afflicted by and not afflicted by CCD. Methods and Principal Findings Of 61 quantified variables (including adult bee physiology, pathogen loads, and pesticide levels), no single measure emerged as a most-likely cause of CCD. Bees in CCD colonies had higher pathogen loads and were co-infected with a greater number of pathogens than control populations, suggesting either an increased exposure to pathogens or a reduced resistance of bees toward pathogens. Levels of the synthetic acaricide coumaphos (used by beekeepers to control the parasitic mite Varroa destructor) were higher in control colonies than CCD-affected colonies. Conclusions/Significance This is the first comprehensive survey of CCD-affected bee populations that suggests CCD involves an interaction between pathogens and other stress factors. We present evidence that this condition is contagious or the result of exposure to a common risk factor. Potentially important areas for future hypothesis-driven research, including the possible legacy effect of mite parasitism and the role of honey bee resistance to pesticides, are highlighted.

  19. Synthetic quorum sensing in model microcapsule colonies

    Shum, Henry; Balazs, Anna C.

    2017-08-01

    Biological quorum sensing refers to the ability of cells to gauge their population density and collectively initiate a new behavior once a critical density is reached. Designing synthetic materials systems that exhibit quorum sensing-like behavior could enable the fabrication of devices with both self-recognition and self-regulating functionality. Herein, we develop models for a colony of synthetic microcapsules that communicate by producing and releasing signaling molecules. Production of the chemicals is regulated by a biomimetic negative feedback loop, the “repressilator” network. Through theory and simulation, we show that the chemical behavior of such capsules is sensitive to both the density and number of capsules in the colony. For example, decreasing the spacing between a fixed number of capsules can trigger a transition in chemical activity from the steady, repressed state to large-amplitude oscillations in chemical production. Alternatively, for a fixed density, an increase in the number of capsules in the colony can also promote a transition into the oscillatory state. This configuration-dependent behavior of the capsule colony exemplifies quorum-sensing behavior. Using our theoretical model, we predict the transitions from the steady state to oscillatory behavior as a function of the colony size and capsule density.

    Ant colony optimization algorithm for continuous domains is a major research direction for ant colony optimization algorithm. In this paper, we propose a distribution model of ant colony foraging, through analysis of the relationship between the position distribution and food source in the process of ant colony foraging. We design a continuous domain optimization algorithm based on the model and give the form of solution for the algorithm, the distribution model of pheromone, the update rules of ant colony position, and the processing method of constraint condition. Algorithm performance against a set of test trials was unconstrained optimization test functions and a set of optimization test functions, and test results of other algorithms are compared and analyzed to verify the correctness and effectiveness of the proposed algorithm.

    The optimum solution of the production scheduling problem for manufacturing processes at an enterprise is crucial as it allows one to obtain the required amount of production within a specified time frame. Optimum production schedule can be found using a variety of optimization algorithms or scheduling algorithms. Ant colony optimization is one of well-known techniques to solve the global multi-objective optimization problem. In the article, the authors present a solution of the production scheduling problem by means of an ant colony optimization algorithm. A case study of the algorithm efficiency estimated against some others production scheduling algorithms is presented. Advantages of the ant colony optimization algorithm and its beneficial effect on the manufacturing process are provided.

    Full Text Available Nos últimos anos um número relativamente grande de sistemas especialistas têm sido produzidos, tanto pela indústria quanto em centros de pesquisa. Algumas destas aplicações têm sido empregadas para resolver problemas práticos, mas a maior parte delas não foi além do estágio de protótipo. Estes sistemas são normalmente desenvolvidos através de um processo relativamente informal e empírico, o qual envolve a implementação de um protótipo simplificado já nos estágios iniciais de aquisição do conhecimento. Esta abordagem tem sido bastante criticada pelas dificuldades de re-implementaçâo do conhecimento. Mais recentemente, algumas metodologias formais para a produção de sistemas especialistas têm sido propostas. Embora tais metodologias prescrevam diversas recomendações úteis, que podem ser seguidas em inúmeros casos práticos, nenhuma delas provou ainda ser aplicável de forma integral em uma ampla gama de situações. A primeira parte deste artigo consiste em uma rápida revisão das principais metodologias propostas. A segunda parte descreve o procedimento adotado durante o desenvolvimento de um sistema especialista para o planejamento de conjuntos habitacionais, denominado House Planner.Several knowledege based systems have been produced in the last decade, both in the industry and in research institutes. Some of these applications have been used in practical situations, but most of them have not been developed beyond the prototype stage. Such systems are usually desingned through an informal and empiric process which involves the implementation of a simple prototype of the system in the early phases of knowledge acquisition. This approach has beem widely criticized because it can make both the re-implementation and updating of knowledege bases cubersome, and seriously distort the way knowledge is represented. For this reason, a number of more formal methodologies for developing knowledge based systems have been

    Full Text Available Colony Collapse Disorder (CCD has become a global problem for beekeepers and for the crops that depend on bee pollination. While many factors are known to increase the risk of colony collapse, the ectoparasitic mite Varroa destructor is considered to be the most serious one. Although this mite is unlikely to cause the collapse of hives itself, it is the vector for many viral diseases which are among the likely causes for Colony Collapse Disorder. The effects of V. destructor infestation differ from one part of the world to another, with greater morbidity and higher colony losses in European honey bees (EHB in Europe, Asia and North America. Although this mite has been present in Brazil for many years, there have been no reports of colony losses amongst Africanized Honey Bees (AHB. Studies carried out in Mexico have highlighted different behavioral responses by the AHB to the presence of the mite, notably as far as grooming and hygienic behavior are concerned. Could these explain why the AHB are less susceptible to Colony Collapse Disorder? In order to answer this question, we have developed a mathematical model of the infestation dynamics to analyze the role of resistance behavior by bees in the overall health of the colony, and as a consequence, its ability to face epidemiological challenges.

    Regeneration is widely distributed among the metazoans. However, clear differences exist as to the degree of regenerative capacity: some phyla can only replace missing body parts, whereas others can generate entirely new individuals. Ascidians are animals that possess a remarkable regenerative plasticity and exhibit a great diversity of mechanisms for asexual propagation and survival. They are marine invertebrate members of the subphylum Tunicata and represent modern-day descendants of the chordate ancestor; in their tadpole stage they exhibit a chordate body plan that is resorbed during metamorphosis. Solitary species grow into an adult that can reach several centimeters in length, whereas colonial species grow by asexual propagation, creating a colony of genetically identical individuals. In this review, we present an overview of the biology of colonial ascidians as a paradigm for study in stem cell and regenerative biology. Focusing on botryllid ascidians, we introduce the potential roles played by multipotent epithelia and multipotent/pluripotent stem cells as source of asexual propagation and regenerative plasticity in the different budding mechanisms, and consider the putative mechanism of body repatterning in a non-embryonic scenario. We also discuss the involvement of intra-colony homeostatic processes in regulating budding potential, and the functional link between allorecognition, chimerism, and regenerative potential.

  4. Order and instabilities in dense bacterial colonies

    2012-02-01

    The structure of cell colonies is governed by the interplay of many physical and biological factors, ranging from properties of surrounding media to cell-cell communication and gene expression in individual cells. The biomechanical interactions arising from the growth and division of individual cells in confined environments are ubiquitous, yet little work has focused on this fundamental aspect of colony formation. By combining experimental observations of growing monolayers of non-motile strain of bacteria Escherichia coli in a shallow microfluidic chemostat with discrete-element simulations and continuous theory, we demonstrate that expansion of a dense colony leads to rapid orientational alignment of rod-like cells. However, in larger colonies, anisotropic compression may lead to buckling instability which breaks perfect nematic order. Furthermore, we found that in shallow cavities feedback between cell growth and mobility in a confined environment leads to a novel cell streaming instability. Joint work with W. Mather, D. Volfson, O. Mondrag'on-Palomino, T. Danino, S. Cookson, and J. Hasty (UCSD) and D. Boyer, S. Orozco-Fuentes (UNAM, Mexico).

  5. Latin America: Essays Interpretating Colonial Legacy

    Directory of Open Access Journals (Sweden)

    María Pia López

    2013-12-01

    Full Text Available A large part of the Latin–American literature of the 19th and 20th century tried to deal with the national question intertwining different dimensions: the weight of colonial legacy, the cultural peculiarity of the nation and the inner relations between social classes and ethnic groups. Thinking the nation implied, in any case, to think the difference and the conflict with others, as well as the inner conflict and the logic of local colonialism. Analyzing some of these essays that played a central role in such process of recasting the origin of the nation, the author moves around three main axes: the formulation of dualist writings (colonial/national; white /indigenous; civilization/wilderness, the issue of language (the language inherited from the colonial experience versus the multilingual nature of indigenous Latin American societies, and the hypothesis about the birth of the nation – appointed to different groups – and its normal functioning as legitimization of the order sprung from independences.

A área de estudo pertence à Bacia Hidrográfica do Rio Mogi-Guaçu. Os dados de superfície que foram empregados na calibração e validação do Rn, foram obtidos de duas torres micrometeorológicas instaladas em áreas de cerrado e de cana-de-açúcar. Foram utilizadas imagens do sensor MODIS e as metodologias empregadas foram SEBAL, METRIC e o modelo proposto por Bisht et al. O Rn no cerrado se mostrou sempre maior que o da cana-de-açúcar evidenciando que, nessas áreas nativas, há, portanto, uma maior quantidade de energia a ser convertida em calor sensível e latente. As metodologias empregadas mostraram-se bastante satisfatórias, havendo um melhor desempenho da metodologia METRIC. O fato da metodologia de Bisht et al. não necessitar de dados de superfície mostra-se bastante útil, já que na falta de medições de superfície tem-se a opção prática e sem custo para o usuário de fazer as estimativas do saldo de radiação.

    Termites of the genus Reticulitermes are widespread invaders, particularly in urban habitats. Their cryptic and subterranean lifestyle makes them difficult to detect, and we know little about their colony dynamics over time. In this study we examined the persistence of Reticulitermes flavipes (Kollar) colonies in the city of Paris over a period of 15 years. The aim was (1) to define the boundaries of colonies sampled within the same four areas over two sampling periods, (2) to determine whether the colonies identified during the first sampling period persisted to the second sampling period, and (3) to compare the results obtained when colonies were delineated using a standard population genetic approach versus a Bayesian clustering method that combined both spatial and genetic information. Herein, colony delineations were inferred from genetic differences at nine microsatellite loci and one mitochondrial locus. Four of the 18 identified colonies did not show significant differences in their genotype distributions between the two sampling periods. While allelic richness was low, making it hard to reliably distinguish colony family type, most colonies appeared to retain the same breeding structure over time. These large and expansive colonies showed an important ability to fuse (39% were mixed-family colonies), contained hundreds of reproductives and displayed evidence of isolation-by-distance, suggesting budding dispersal. These traits, which favor colony persistence over time, present a challenge for pest control efforts, which apply treatment locally. The other colonies showed significant differences, but we cannot exclude the possibility that their genotype distributions simply changed over time.

  12. Ireland – a test case of Post-colonialism / Post colonialism

    Directory of Open Access Journals (Sweden)

    2006-05-01

    Full Text Available Contextualisation This review attempts to set the stage for post-colonial theorising, in the light of alternative representations of ‘whiteness’, on issues of gender, race and language within the discourse of equality. In this paper Ireland and the Irish provide a backdrop against which the nature and impact of colonialism on the colonised and the coloniser are explored. Many challenging questions emerge about the ideological basis of post colonial theory, not least when traditional paradigms of racism, as conveyed by the black / white dichotomy, are examined: Ireland presents a context, it is argued, where subjugation is of white on white. Linked to this is the language of the coloniser, a powerful hegemonic force which, in some situations, has been nurtured by the colonised and later developed into a text which is unique, producing a new literature which, it is asserted, truly invokes the ‘post colonial’. Abstract: Post-colonialism – essentially a critique of colonialism, is characterised by a process of disengagement from the colonial epoch and has taken many forms. In this article a set of phenomena are examined that have become inscribed in the cultures of the colonised with a view to identifying alternative cultural origins and dispositions recovered in this post-colonial era. Ireland and the Irish provide the background context of this exploration into perspectives generated by the peripheral or post-colonial nations. Globalisation, too, has had a role to play in the increasing de-territorialisation of communities as a result of cross-frontier mobility, increased intra-community mobility and new communication technologies. A critical reflection on the process of disengagement leads the author to conclude that we must come to recognise new cultural forms which are accepting of a heterogeneous and inclusive society: one which is not characterised by difference.

  14. Influence of feeding bee colonies on colony strenght and honey authenticity

    Directory of Open Access Journals (Sweden)

    Andreja KANDOLF BOROVŠAK

    2015-12-01

    Full Text Available For the natural development of bee colonies, there is the need for appropriate nutrition. Lack of natural honey flow must be supplemented by feeding bee colonies with sugar syrups or candy paste. This supplementary feeding encourages brood breeding and forage activity, whereby stronger colonies collect more honey. Sugar syrups can cause honey adulteration, which is more frequent with the reversing of the brood combs with the bee food, with the combs moved from the brood chamber to the upper chamber. Authentication of honey from the standpoint of the presence of sugar syrup is very complex, because there is no single method by which honey adulteration can be reliably confirmed. Feeding the colonies in spring should result in stronger colonies and hence the collection of more honey in the brood chambers. The objective of the present study was to determine whether this has effects also on honey authenticity, and to discover a simple method for detection of honey adulteration. The colonies were fed with candy paste that had added yeast and blue dye, to provide markers for detection of honey adulteration. The strength of the colonies and quantity of honey in the brood chambers were monitored. The results of the analysis of stable isotope and activity of foreign enzymes were compared with the results of yeast quantity and colour of the honey (absorbance, L*, a*, b* parameters. Detection of yeast in the honey samples and presence of colour as a consequence of added dye appear to be appropriate methods to follow honey adulteration, and further studies are ongoing.

Nossas hipóteses partem da convicção de que tais constructos dão conta dessas especificidades, potencializando o conhecer como um ser-agir em convivência. Procuramos demonstrar essa perspectiva, nesse texto, procedendo à descrição do funcionamento do Grupo de Ações e Investigações Autopoiéticas - GAIA, colocando-nos como sujeitos das ações de pesquisa, como observadores implicados no ato mesmo de observar, o que vincula este estudo às abordagens autopoiéticas e metacognitivas. O desafio é possibilitar, a partir de vivências dialógicas em ambientes complexos como as redes presenciais e virtuais de aprendizagens, novas compreensões acerca da inseparabilidade do conhecer-viver como fluxo passível de aplicação na educação. Articulando pesquisas de diferentes áreas do conhecimento, os pesquisadores envolvidos com o GAIA tendem a convergir na defesa de uma educação que se tece junto; que faz emergir o respeito mútuo, a amorosidade e também a morosidade necessária ao ser-agir na consciência de que cada organismo conspira para a vida com seu próprio ritmo e implicações cósmicas. Nossas conclusões apontam para vínculos significativos entre os recortes teóricos apresentados e a compreensão do observar-agir com um modo de pesquisar e de aprender, tendo como veículos as narrativas do grupo em convergências diversas, processo que nominamos como ontoepistemogênese.

Cambridge, MA: Harvard University Press, 2011. 500 pp. $50 (cloth.In South Korea, more so than in most other postcolonial countries, the issue of sovereignty and the colonial past remains a central feature of politics. Most recently, during a televised presidential debate on December 4, 2012, Lee Jung-hee of the Unified Progressive Party said something that likely had never been said on South Korean television: “Takaki Masao signed an oath of loyalty [to the Emperor of Japan], in his own blood, to become an officer in the Japanese [Imperial] Army. You know who he is. His Korean name is Park Chung Hee.” Lee Jung-hee then made the connection between that colonial past and the willingness to sell out the nation’s sovereignty in the present. The conservative candidate Park Geun-hye, the daughter of the late President Park Chung Hee who ruled South Korea from 1961 through 1979, and members of Park’s Saenuri Party, remain true to their “roots”: these “descendants of pro-Japanese collaborators and dictators” (again sold out South Korea’s sovereignty (on November 22, 2011 when they rammed the US-ROK Free Trade Agreement through the National Assembly.

    The determinants of Colony Collapse Disorder (CCD), a particular case of collapse of honey bee colonies, are still unresolved. Viruses including the Israeli acute paralysis virus (IAPV) were associated with CCD. We found an apiary with colonies showing typical CCD characteristics that bore high loads of IAPV, recovered some colonies from collapse and tested the hypothesis if IAPV was actively replicating in them and infectious to healthy bees. We found that IAPV was the dominant pathogen and ...

    Many complex factors have been linked to the recent marked increase in honey bee colony failure, including pests and pathogens, agrochemicals, and nutritional stressors. It remains unclear, however, why colonies frequently react to stressors by losing almost their entire adult bee population in a short time, resulting in a colony population collapse. Here we examine the social dynamics underlying such dramatic colony failure. Bees respond to many stressors by foraging earlier in life. We manipulated the demography of experimental colonies to induce precocious foraging in bees and used radio tag tracking to examine the consequences of precocious foraging for their performance. Precocious foragers completed far fewer foraging trips in their life, and had a higher risk of death in their first flights. We constructed a demographic model to explore how this individual reaction of bees to stress might impact colony performance. In the model, when forager death rates were chronically elevated, an increasingly younger forager force caused a positive feedback that dramatically accelerated terminal population decline in the colony. This resulted in a breakdown in division of labor and loss of the adult population, leaving only brood, food, and few adults in the hive. This study explains the social processes that drive rapid depopulation of a colony, and we explore possible strategies to prevent colony failure. Understanding the process of colony failure helps identify the most effective strategies to improve colony resilience. PMID:25675508

    2016-06-01

    Full Text Available Official and/or public archives were a byproduct of colonial rule in Africa. (Archives are a byproduct of administrative governance everywhere. Given the density and diversity of colonial archival records, historians have tended to rely on them for the study of the colonial period. Publications on the use of archives have not captured the perspective of end-users, who often face peculiar challenges in the use of colonial and metropolitan archives. This paper provides an end-user perspective on colonial archives in Nigeria and the United Kingdom. It highlights the challenges of data collection and prospects of optimal use of archival source material. The discussion is of general application to users of colonial archives especially in the former British colonies in Africa.

    Full Text Available Sexual recruitment of the staghorn coral, Acropora cervicornis, is accepted to be very rare. Instead, these branching corals proliferate through fragmentation leading to dense mono-specific and possibly monoclonal stands. For acroporid corals, which have suffered drastic population declines, dominance of asexual reproduction results in low levels of genotypic diversity and limited ability to re-colonize extirpated areas. Small colonies with a single encrusting, symmetrical base, and few incipient branches are frequently presumed to be the result of a settled planula (i.e. sexual reproduction. Here, we show that colonies fitting this description (i.e., presumed sexual recruits can result from asexual fragmentation. Acropora cervicornis colonies (~20 cm diameter were tagged and observed over eighteen months. In several cases, colony offshoots fused with the adjacent substrate forming secondary disc-like attachment points. Following natural fragmentation, these discs of tissue became separated from the original colony, and were observed to heal and give rise to smaller colonies with striking similarity to the expected morphology of a sexual recruit. Thus, presuming a colony is a sexual recruit based on appearance is unreliable and may lead to inflated expectations of genetic diversity among populations. The accurate assessment of recruitment and genetic diversity is crucial to predicting the recovery potential of these imperiled and ecologically irreplaceable reef corals. Rev. Biol. Trop. 54 (Suppl. 3: 145-151. Epub 2007 Jan. 15.Se ha aceptado que el reclutamiento sexual del coral asta de venado, Acropora cervicornis, es muy raro.

En la colonia portuguesa, la identidad negra ha sido transfigurada y la formación de una conciencia colonial surge en discursos que se instalan en la memoria social. En su texto, el padre Antonil elabora determinados valores que transforman su obra en un discurso "barroco-apologético" en torno al universo colonial: "Brasil es infierno de negros, purgatorio de blancos y paraíso de mulatos y mulatas".The narrative Cultura e Opulencia do Brasil por sus Drogas e Minas by Father André João Antonil, describes the processes ofthe colonial Portuguese production in América. The text, published in Lisbon in 1711, contains both objective andpractical information, transformed and influenced by 'literary baroque'. The narrator wanders from realistic transcription to baroque subjectivity, and we may perceive a playful character in his morality sermons, as he sometimes uses extreme metaphors belonging to the sugar mili scene. In the Portuguese colony, the black identity has been transfigured and the formation of a colonial conscience arises in speeches that have taken roots in a collective memory. Father Antonil elaborates those valúes which help to transform his work into a 'baroque-apologetic' speech about the colonial world: "Brazil is the hell of blacks, the purgatory of whites and the paradise of mulatto men and w ornen ".

A idéia básica é estabelecer um número máximo de visitantes em uma determinada localidade, com o objetivo de minimizar os impactos provocados pela visitação. Entretanto, esta metodologia está incompleta ao atrelar os impactos da visitação apenas ao número de visitantes, deixando de considerar aspectos subjetivos e qualitativos relacionados ao turismo. Esta pesquisa demonstra a falta de cientificidade desta metodologia e salienta que limitar o número de visitantes é apenas um dos métodos de controle dos impactos provocados pelo turismo.

  18. Intraspecific Variation among Social Insect Colonies: Persistent Regional and Colony-Level Differences in Fire Ant Foraging Behavior.

    Directory of Open Access Journals (Sweden)

    Alison A Bockoven

    Full Text Available Individuals vary within a species in many ecologically important ways, but the causes and consequences of such variation are often poorly understood. Foraging behavior is among the most profitable and risky activities in which organisms engage and is expected to be under strong selection. Among social insects there is evidence that within-colony variation in traits such as foraging behavior can increase colony fitness, but variation between colonies and the potential consequences of such variation are poorly documented. In this study, we tested natural populations of the red imported fire ant, Solenopsis invicta, for the existence of colony and regional variation in foraging behavior and tested the persistence of this variation over time and across foraging habitats. We also reared single-lineage colonies in standardized environments to explore the contribution of colony lineage. Fire ants from natural populations exhibited significant and persistent colony and regional-level variation in foraging behaviors such as extra-nest activity, exploration, and discovery of and recruitment to resources. Moreover, colony-level variation in extra-nest activity was significantly correlated with colony growth, suggesting that this variation has fitness consequences. Lineage of the colony had a significant effect on extra-nest activity and exploratory activity and explained approximately half of the variation observed in foraging behaviors, suggesting a heritable component to colony-level variation in behavior.

  19. Globalization in the post - colonial world

    2016-01-01

    Full Text Available The paper presents a new interpretation of globalization within the boundaries of the author’s concept of soft globalization, which exploits a normatively attractive alternative to the concept of the Empire. It is argued here that the conditions of development of contemporary post - colonial world communities do not require any unification in the form of the Empire, but instead the creation of a non repressive mechanism of social regulation - the implementation of a form of soft globalization, a globalization with a mental form are expedient here. Historically, globalization occurred in a strict material(i.e. economical and military form that prompted the conditions for the evolution of civilization as the Empire: a case in which the development of the world occurs under the power of a single dominating state. Imperialistic politics leads to colonial politics formation. The history of the phenomena of civilization shows many instances of Empire globalization. Globalization in the Empire form was already observed at the time of the Roman Empire. At this time processes of development inside the Empire were manifestations of globalization in its highest cultural shape. But ancient Rome was also a social and political experiment that acquired the attributes of a purely material globalization in the end, and historically brought about the irreversible crash of the Roman Empire itself. Contemporary fluctuations referring to the process of globalization can be registered in the US’s attempts of material domination inside this or that existing case of civilization, which causes colonialism appearance. The main idea stressed in the paper is that only a mental globalization could succeed in the end.

    Full Text Available El barroco latinoamericano se concibe generalmente como una época en la que una sociedad heterogénea se reunía en tomo a rituales públicos que manifestaban las ideologías políticas y religiosas de un monarca distante. La dimensión pública se impone de manera tan nítida en las crónicas del siglo XVII y principios del XVIII que nos lleva a pensar que, tal como Philippe Aries observó para la Edad Media en Europa, lo público y lo privado no siempre se distinguían en las ciudades coloniales. Allí, el individuo estaba inserto en solidaridades colectivas, y si bien la casa colonial no era un lugar accesible a cualquiera, distaba mucho de ser un refugio de la mirada de los demás.

    This report summarizes progress in the second year of this project. The objective is to develop methods and software to predict the spatial configuration, properties and temporal evolution of microbial colonies in the subsurface. To accomplish this, we integrate models of intracellular processes, cell-host medium exchange and reaction-transport dynamics on the colony scale. At the conclusion of the project, we aim to have the foundations of a predictive mathematical model and software that captures the three scales of these systems – the intracellular, pore, and colony wide spatial scales. In the second year of the project, we refined our transcriptional regulatory network discovery (TRND) approach that utilizes gene expression data along with phylogenic similarity and gene ontology analyses and applied it successfully to E.coli, human B cells, and Geobacter sulfurreducens. We have developed a new Web interface, GeoGen, which is tailored to the reconstruction of microbial TRNs and solely focuses on Geobacter as one of DOE’s high priority microbes. Our developments are designed such that the frameworks for the TRND and GeoGen can readily be used for other microbes of interest to the DOE. In the context of modeling a single bacterium, we are actively pursuing both steady-state and kinetic approaches. The steady-state approach is based on a flux balance that uses maximizing biomass growth rate as its objective, subjected to various biochemical constraints, for the optimal values of reaction rates and uptake/release of metabolites. For the kinetic approach, we use Karyote, a rigorous cell model developed by us for an earlier DOE grant and the DARPA BioSPICE Project. We are also investigating the interplay between bacterial colonies and environment at both pore and macroscopic scales. The pore scale models use detailed representations for realistic porous media accounting for the distribution of grain size whereas the macroscopic models employ the Darcy-type flow

    It is well established that the haptophyte Phaeocystis antarctica is a dominant member of the Ross Sea phytoplankton, contributing more than half of the annual production. Its broad spatial distribution has been documented by ship sampling, but its mesoscale variations are poorly known. In the PRISM (Processes Regulating Iron Supply at the Mesoscale) project in 2011, we deployed a Video Plankton Recorder (VPR) for 24 h between selected locations that had been identified by satellite images to have eddy-like features. As P. antarctica colonies are far larger than the VPR's camera resolution (2 mm vs. 40 µm), we were able to quantify colonial contributions to total fluorescence and particulate organic carbon, resolving distances of a few kms and depths of ca. 1 m. Within these surveys, we found unusual forms of colonies, which we subsequently deemed "ghost colonies"; that is, colonies that have largely lost their cells and have collapsed. While ghost colonies generally were located deeper in the water column than intact colonies, not all surface Phaeocystis blooms were associated with ghost colonies. For example, in one survey ghost colonies and intact colonial forms were present throughout the water column, but with distributions separated by depth; while in another survey, their distributions appeared to be spatially distinct in the horizontal. We hypothesize that ghost colonies are formed upon extreme micronutrient stress, which causes colonies to sink and cells to be liberated from colonies. Considerable mesoscale variability was noted in P. antarctica distributions and was related to oceanographic features. The mesoscale variations in both P. antarctica and its ghost colonies potentially have significant impacts on vertical fluxes and biogeochemical cycles in the Ross Sea.

    This paper focus on establishing an optimization methodology for maximizing the draft tube performance as a function of the inlet velocity profile. The overall work is defined by four steps: the inlet velocity profile parametrization, the numerical optimization set-up, the numerical computational fluid dynamics (CFD) draft tube model and the objective function definition. However as the inlet velocity profile is a new challenge, each step of the parametrization must be properly validated. In the first step, a suitable parametrization with an appropriate number of variables is chosen to approximate an experimental draft tube inlet velocity profile. The second step considers the reduction of the actual numerical model to develop the CFD calculations. In the third step, the optimization algorithm set-up is specified. Finally, the objective function is evaluated. As each step is properly validated, it is considered this proved methodology will help to find an inlet velocity profile shape which will be able to suppress or mitigate the undesirable draft tube flow characteristics.

    The present document raises a methodology for the elaboration of the Energy Balance of the Metropolitan Zone of the Valley of Mexico (ZMVM), in order to unify criteria and to facilitate the work of entities and investigators, mainly of those that require the entailment of energy and environment. The applied methodology, the consolidated format and the caloric unity facilitates the insertion of the Energy Balance of the ZMVM within the National Balance of Energy. The regional balances of energy have the intention of knowing the energy consumption patterns in the ZMVM and the indexes of energy intensity by sector. They establish the relationship of the indexes of energy intensity with the local and global air quality of the region, performing studies of incidence with the main polluting agents and with the greenhouse effect gases. [Spanish] El presente documento plantea una metodologia para la elaboracion del Balance de Energia de la Zona Metropolitana del Valle de Mexico (ZMVM), con el proposito de unificar criterios y facilitar el trabajo de organismos e investigadores, sobre todo de aquellos que requieren vincular energia y medio ambiente.

Los balances regionales de energia tienen el proposito de conocer los patrones de consumo de energia en la ZMVM y los indices de intensidad energetica por sector. Establecen la relacion de los indices de intensidad energetica con la calidad del aire local y global de la region, realizando estudios de incidencia con los principales contaminantes y con los gases de efecto invernadero.

  11. CHRISTIANITY AND COLONIALISM IN SOME ENGLISH SHORT STORIES

    Full Text Available Colonial and postcolonial studies are often linked to the power domination of the West upon the East in the way that the East economically, politically, and socially oppressed. Colonialism is often associated with three elements, the explorers dealing with geographical information, missionaries approaching the local people culturally, and the colonial administrators ruling the colony. Gold, glory, and gospel are the European’s concern. However, in representing the relation between Christianity and colonialism there is critical dialectic amongst historians, anthropologists, Christian missions, or cultural critics. Some propose that Christianity is considered to be the religious arm of colonialism. Others state that Christianity is spread without any secular interest as it is a great commandment of Jesus Christ. A few believe that Christianity give critical resistance against colonialism. The relation between Christianity and colonialism cannot be simplified as being neutral, in complicity, or in opposition. So, it is worth-discussing to understand how European writers construct the relation between Christianity and colonialism in their literary work. How Christianity is constructed and how Christianity is related to colonialism will be discussed in this paper. Using postcolonial paradigm, two English short stories will be analyzed in that way. They are Rudyard Kipling’s “Lispeth” and Doris Lessing’s “No Witchcraft for Sale”.

  12. Colony age, neighborhood density and reproductive potential in harvester ants.

    At about age 5 years, colonies of the harvester ant, Pogonomyrmex barbatus, begin to produce winged, sexual forms (alates) that mate in large annual aggregations. We examined how colony age and neighborhood density affect the numbers, body mass, and body fat of alates produced by 172 colonies ranging in age from 4 to 17 years. Over one-third (36%) of all colonies produced no alates. Failure to reproduce was independent of colony age. Of those colonies that did produce alates, older colonies produced more alates than younger colonies. Older colonies produced lighter female alates (in dry mass), but the total biomass of additional alates produced by older colonies far outweighed the reduced allocation to female alate body mass. Body fat content was much higher in female alates (36.0% on average) than in males (3.7% on average). Alate body fat content was not related to colony age. The fitness of female alates may be related to their fresh body mass; that of females captured after mating and reared in the laboratory was positively correlated with egg-laying rate, although not with the total number of eggs in the first brood. Neighborhood density was not related to alate number, mass, or fat content, in contrast to the results of a 1995 study at the site, in which alate numbers were negatively related to neighborhood density. Thus the influence of crowding on reproductive output appears to vary from year to year, perhaps in response to variation in rainfall and food supply. Alate output by individual colonies was correlated among years. These results suggest that a few, older colonies dominate the pool of reproductives year after year.

  13. Effect of fluid motion on colony formation in Microcystis aeruginosa

    Full Text Available Microcystis aeruginosa, generally occurring in large colonies under natural conditions, mainly exists as single cells in laboratory cultures. The mechanisms involved in colony formation in Microcystis aeruginosa and their roles in algal blooms remain unknown. In this study, based on previous research findings that fluid motion may stimulate the colony formation in green algae, culture experiments were conducted under axenic conditions in a circular water chamber where the flow rate, temperature, light, and nutrients were controlled. The number of cells of Microcystis aeruginosa, the number of cells per colony, and the colonial characteristics in various growth phases were observed and measured. The results indicated that the colony formation in Microcystis aeruginosa, which was not observed under stagnant conditions, was evident when there was fluid motion, with the number of cells per largest colony reaching 120 and the proportion of the number of cells in colonial form to the total number of cells and the mean number of cells per colony reaching their peak values at a flow rate of 35 cm/s. Based on the analysis of colony formation process, fluid motion stimulates the colony formation in Microcystis aeruginosa in the lag growth phase, while flushes and disaggregates the colonies in the exponential growth phase. The stimulation effect in the lag growth phase may be attributable to the involvement of fluid motion in a series of physiological processes, including the uptake of trace elements and the synthesis and secretion of polysaccharides. In addition, the experimental groups exhibiting typical colonial characteristics in the lag growth phase were found to have higher cell biomass in the later phase.

    Full Text Available On the presupposition that the conquest of the Canary Islands set the colonial stage for the later Spanish enterprises in the Americas, the author discusses a number of elements of identity shared by the islands of both the eastern Atlantic and the Caribbean. Sugar, the slave trade and the raising of bananas, cochineal and tobacco are the instances chosen for this comparative analysis. In addition, the author makes a reference to the legends of the apparition of the Virgin of Charity at El Cobre, in Cuba, and of Candlemas in Tenerife.

    Partiendo de la idea de que la conquista de las Islas Canarias fue el primer ensayo colonial de lo que luego desarrollarían los españoles en América, se examinan algunos elementos de identidad entre el mundo isleño atlántico y caribeño, producidos precisamente por esa situación inicial de dominio colonial.

Finalmente se hace una referencia comparativa de las leyendas de la aparición de la Virgen de la Caridad del Cobre en Cuba y de la Virgen de Candelaria en Tenerife

  17. O ESTUDO DE CASOS NA PERSPECTIVA DA METODOLOGIA JURÍDICO-FILOSÓFICA

    2009-12-01

    Full Text Available Durante o predomínio do Idealismo iluminista e na época do Positivismo exegético e jurídico dos séc. XIX e XX, pode-se afirmar que o método de estudo de casos no Direito foi deixado em segundo plano. Atualmente, esse método apresenta uma importância inegável, correspondendo a uma resposta ao dogmatismo anterior. Entretanto, é possível apontar que o estudo de casos também representa um retorno a padrões de percepção do fenômeno jurídico que sempre estiveram presentes na tradição jurídica ocidental, de uma forma ou de outra. É o que se nota quando se faz alusão à metodologia das ciências práticas que advém da tradição filosófica grega de Platão e Aristóteles e que se aperfeiçoa com o Direito romano e com os estudos medievais. Com isso, busca-se provar que o estudo de casos no Direito não é fruto somente de uma pretensa influência do Common Law, como vários autores afirmam ao vincular a uma visão empirista tipicamente desse sistema; há sim, por outro lado, raízes na própria experiência jurídica do sistema romano-germânico que levam a tal valorização do caso, principalmente a partir da construção romana.

    2010-07-13

    Using computational modeling, we design colonies of biomimetic microcapsules that exploit chemical mechanisms to communicate and alter their local environment. As a result, these synthetic objects can self-organize into various autonomously moving structures and exhibit ant-like tracking behavior. In the simulations, signaling microcapsules release agonist particles, whereas target microcapsules release antagonist particles and the permeabilities of both capsule types depend on the local particle concentration in the surrounding solution. Additionally, the released nanoscopic particles can bind to the underlying substrate and thereby create adhesion gradients that propel the microcapsules to move. Hydrodynamic interactions and the feedback mechanism provided by the dissolved particles are both necessary to achieve the collective dynamics exhibited by these colonies. Our model provides a platform for integrating both the spatial and temporal behavior of assemblies of "artificial cells," and allows us to design a rich variety of structures capable of exhibiting complex, cooperative behavior. Due to the cell-like attributes of polymeric microcapsules and polymersomes, material systems are available for realizing our predictions.

    Full Text Available The period of British rule from 1757 to 1900 is marked by major sociopolitical changes and scientific breakthroughs that impacted medical systems, institutions, and practitioners in India. In addition, historians have debated whether the colonial regime used Western medicine as a tool to expand and legitimize its rule. This paper reviews the secondary literature on this subject with emphasis on the individual physicians. During this period, the practice of "Doctory" or Western medicine gained momentum in India, buoyed with the support of the British as well as Western-educated Indians. Many Indians were trained in Western medicine and employed by the administration as "native doctors" in the subordinate medical service, and the superior medical service by and large comprised Europeans. The colonial regime gradually withdrew most of its patronage to the indigenous systems of medicine. The practitioners of these systems, the vaidyas and the hakims, suffered significant loss of prestige against Western medicine′s claims of being a more rational "superior" system of medicine. Some of them became purists and defended and promoted their systems, while others adopted the methods and ideas of Western medicine into their education and practice. European doctors now rarely interacted with practitioners of Indian systems, but seriously pursued research into medicinal plants and tropical diseases. There is no mention of specialist physicians in this period, and all physicians and surgeons were generalists. Folk practitioners continued to be popular among the masses.

    Full Text Available In 1948, a small colony of emperor penguins Aptenodytes forsteri was discovered breeding on Emperor Island (67° 51' 52″ S, 68° 42' 20″ W, in the Dion Islands, close to the West Antarctic Peninsula (Stonehouse 1952. When discovered, the colony comprised approximately 150 breeding pairs; these numbers were maintained until 1970, after which time the colony showed a continuous decline. By 1999 there were fewer than 20 pairs, and in 2009 high-resolution aerial photography revealed no remaining trace of the colony. Here we relate the decline and loss of the Emperor Island colony to a well-documented rise in local mean annual air temperature and coincident decline in seasonal sea ice duration. The loss of this colony provides empirical support for recent studies (Barbraud & Weimerskirch 2001; Jenouvrier et al 2005, 2009; Ainley et al 2010; Barber-Meyer et al 2005 that have highlighted the vulnerability of emperor penguins to changes in sea ice duration and distribution. These studies suggest that continued climate change is likely to impact upon future breeding success and colony viability for this species. Furthermore, a recent circumpolar study by Fretwell & Trathan (2009 highlighted those Antarctic coastal regions where colonies appear most vulnerable to such changes. Here we examine which other colonies might be at risk, discussing various ecological factors, some previously unexplored, that may also contribute to future declines. The implications of this are important for future modelling work and for understanding which colonies actually are most vulnerable.

  10. Colony patterning and collective hyphal growth of filamentous fungi

    Science.gov (United States)

    Matsuura, Shu

    2002-11-01

    Colony morphology of wild and mutant strains of Aspergillus nidulans at various nutrient and agar levels was investigated. Two types of colony patterning were found for these strains. One type produced uniform colonies at all nutrient and agar levels tested, and the other exhibited morphological change into disordered ramified colonies at low nutrient levels. Both types showed highly condensed compact colonies at high nutrient levels on low agar media that was highly diffusive. Disordered colonies were found to develop with low hyphal extension rates at low nutrient levels. To understand basic pattern selection rules, a colony model with three parameters, i.e., the initial nutrient level and the step length of nutrient random walk as the external parameters, and the frequency of nutrient uptake as an internal parameter, was constructed. At low nutrient levels, with decreasing nutrient uptake frequency under diffusive conditions, the model colony exhibited onsets of disordered ramification. Further, in the growth process of A. nidulans, reduction of hyphal extension rate due to a population effect of hyphae was found when hyphae form three-dimensional dense colonies, as compared to the case in which hyphal growth was restricted into two-dimensional space. A hyphal population effect was introduced in the colony model. Thickening of colony periphery due to the population effect became distinctive as the nutrient diffusion effect was raised at high nutrient levels with low hyphal growth rate. It was considered that colony patterning and onset of disorder were strongly governed by the combination of nutrient diffusion and hyphal growth rate.

    Neonicotinoid insecticides can cause a variety of adverse sub-lethal effects in bees. In social species such as the honeybee, Apis mellifera, queens are essential for reproduction and colony functioning. Therefore, any negative effect of these agricultural chemicals on the mating success of queens may have serious consequences for the fitness of the entire colony. Queens were exposed to the common neonicotinoid pesticides thiamethoxam and clothianidin during their developmental stage. After mating, their spermathecae were dissected to count the number of stored spermatozoa. Furthermore, their worker offspring were genotyped with DNA microsatellites to determine the number of matings and the genotypic composition of the colony. Colonies providing the male mating partners were also inferred. Both neonicotinoid and control queens mated with drones originating from the same drone source colonies, and stored similar number of spermatozoa. However, queens reared in colonies exposed to both neonicotinoids experienced fewer matings. This resulted in a reduction of the genetic diversity in their colonies (i.e. higher intracolonial relatedness). As decreased genetic diversity among worker bees is known to negatively affect colony vitality, neonicotinoids may have a cryptic effect on colony health by reducing the mating frequency of queens.

    Full Text Available Clustering analysis is used in many disciplines and applications; it is an important tool that descriptively identifies homogeneous groups of objects based on attribute values. The ant colony clustering algorithm is a swarm-intelligent method used for clustering problems that is inspired by the behavior of ant colonies that cluster their corpses and sort their larvae. A new abstraction ant colony clustering algorithm using a data combination mechanism is proposed to improve the computational efficiency and accuracy of the ant colony clustering algorithm. The abstraction ant colony clustering algorithm is used to cluster benchmark problems, and its performance is compared with the ant colony clustering algorithm and other methods used in existing literature. Based on similar computational difficulties and complexities, the results show that the abstraction ant colony clustering algorithm produces results that are not only more accurate but also more efficiently determined than the ant colony clustering algorithm and the other methods. Thus, the abstraction ant colony clustering algorithm can be used for efficient multivariate data clustering.

    Full Text Available Varroa mites and viruses are the currently the high-profile suspects in collapsing bee colonies. Therefore, seasonal variation in varroa load and viruses (Acute-Kashmir-Israeli complex (AKI and Deformed Wing Virus (DWV were monitored in a year-long study. We investigated the viral titres in honey bees and varroa mites from 23 colonies (15 apiaries under three treatment conditions: Organic acids (11 colonies, pyrethroid (9 colonies and untreated (3 colonies. Approximately 200 bees were sampled every month from April 2011 to October 2011, and April 2012. The 200 bees were split to 10 subsamples of 20 bees and analysed separately, which allows us to determine the prevalence of virus-infected bees. The treatment efficacy was often low for both treatments. In colonies where varroa treatment reduced the mite load, colonies overwintered successfully, allowing the mites and viruses to be carried over with the bees into the next season. In general, AKI and DWV titres did not show any notable response to the treatment and steadily increased over the season from April to October. In the untreated control group, titres increased most dramatically. Viral copies were correlated to number of varroa mites. Most colonies that collapsed over the winter had significantly higher AKI and DWV titres in October compared to survivors. Only treated colonies survived the winter. We discuss our results in relation to the varroa-virus model developed by Stephen Martin.

    2015-01-01

    Ant- and ant-colony-inspired ALife art is characterized by the artistic exploration of the emerging collective behavior of computational agents, developed using ants as a metaphor. We present a chronology that documents the emergence and history of such visual art, contextualize ant- and ant-colony-inspired art within generative art practices, and consider how it relates to other ALife art. We survey many of the algorithms that artists have used in this genre, address some of their aims, and explore the relationships between ant- and ant-colony-inspired art and research on ant and ant colony behavior.

Para tanto, foram simulados valores fenotípicos com distribuição simétrica e com distribuição assimétrica à direita e à esquerda, com ou sem a presença de "outliers". A metodologia proposta foi aplicada a um conjunto de dados provenientes de um experimento com 92 genótipos de alfafa (Medicago sativa, avaliados em 20 ambientes, e comparada às metodologias de Eberhart & Russell e de regressão não paramétrica. A metodologia da RQ proporcionou resultados iguais ou superiores aos obtidos com as metodologias alternativas avaliadas. No entanto, a ocorrência de resultados discordantes entre as metodologias evidencia a importância de se avaliar a simetria na distribuição dos valores fenotípicos. Para distribuições simétricas, na presença de "outliers", deve-se utilizar a RQ com valor de quantil estimado (τ em 0,50; na ausência de "outliers", pode-se utilizar tanto a metodologia de Eberhart & Russell quanto a RQ (τ = 0,50. Para distribuições assimétricas, indica-se o uso da RQ com τ = 0,25, para assimetria à direita, e com τ = 0,75, para assimetria à esquerda, independentemente da presença de "outliers".

    A model of a lunar domestic economy is presented which consists of 12 sectors, trading 21 goods and services. Material flow for operations and investments are balanced to minimize shortages and surpluses. Prices are formed by targeting a 15-35% return on assets for industry and a 15% after expenses income for labour. From this data, accounting statements, a 14 × 14 cash flow input/output matrix (consisting of 11 industrial sectors, labour, foreign trade and finance), and macroeconomic analyses are prepared which illuminate the most important links in the lunar economy. From this model conclusions are drawn regarding the matter of how best to lay the basis for sustainable colony growth and prosperity.

    Full Text Available This is a first approach to the application of virtual reconstruction techniques of a colonial house. In Argentina it is still uncommon to perform 3D modeling of archaeological sites and especially in historical archeology. As a first step, we used the Google SketchUp to model the country house located on the banks of the Río de la Plata (Buenos Aires. It has historical significance because it belonged to a Spanish councilman, housed hundreds of slaves and was the place where stayed the troops that carried out the Second British Invasion of Buenos Aires. In this case, the 3D modeling was useful for evaluating the future excavationa and activities of preservation of cultural heritage.

    Full Text Available 10.12957/cadest.2013.15770A metodologia usada atualmente na Embrapa para avaliar os impactos sociais e ambientais das tecnologias geradas pelos seus centros de pesquisa é composta por indicadores ponderados que são dependentes de critérios subjetivos, não permitindo avaliar a influência de cada indicador sobre os demais e nem sobre os índices finais gerados. Desse modo, a proposta deste artigo é definir novos pesos na construção desses índices. O diferencial da metodologia proposta é o uso de métodos estatísticos de análise multivariada na construção dos pesos, oferecendo uma alternativa ao método usado atualmente pelos seus centros de pesquisa. A abordagem metodológica aqui utilizada padroniza todas as variáveis, com o intuito de eliminar a influência de localização e escala. Todas as análises são feitas após o ranqueamento das variáveis, gerando grandezas adimensionais e robustas nas componentes dos índices de impactos social e ambiental. Nota-se que esses índices são analisados separadamente. Ao final da análise conclui-se que a metodologia proposta diminui o grau de subjetividade na escolha dos pesos dos indicadores e ajuda a identificar com mais clareza qual deles exerce maior influência nos índices de impactos das tecnologias analisadas

    Full Text Available The determinants of Colony Collapse Disorder (CCD, a particular case of collapse of honey bee colonies, are still unresolved. Viruses including the Israeli acute paralysis virus (IAPV were associated with CCD. We found an apiary with colonies showing typical CCD characteristics that bore high loads of IAPV, recovered some colonies from collapse and tested the hypothesis if IAPV was actively replicating in them and infectious to healthy bees. We found that IAPV was the dominant pathogen and it replicated actively in the colonies: viral titers decreased from April to September and increased from September to December. IAPV extracted from infected bees was highly infectious to healthy pupae: they showed several-fold amplification of the viral genome and synthesis of the virion protein VP3. The health of recovered colonies was seriously compromised. Interestingly, a rise of IAPV genomic copies in two colonies coincided with their subsequent collapse. Our results do not imply IAPV as the cause of CCD but indicate that once acquired and induced to replication it acts as an infectious factor that affects the health of the colonies and may determine their survival. This is the first follow up outside the US of CCD-colonies bearing IAPV under natural conditions.

    Full Text Available RESUMO: A toracoscopia assume cada vez mais um papel importante no diagnóstico e terapêutica de muitos doentes com derrames pleurais recidivantes. É um método simples e bern tolerado, com elevado valor diagnóstico, permitindo uma intervenção mais precoce. Além do diagnóstico permite controlar derrames pleurais recidivantes e malignos, o que poderá complementarmente ter importância de ordem clínica no tratamento e melboria da qualidade de vida do doente. Apesar do número de complicações reduzido e da sua pequena importância, pensamos que se trata de uma técnica a indicar em base individual, tendo em conta o risco/beneficio. Os autores abordam a técnica e metodologia utilizada na toracoscopia, suas contra-indicações, complicações e indicações, fazendo uma revisão teórica dos resultados descritos na literatura e realçando a modalidade anestésica que utilizam: a anestesia local com ajuda de pré-medicação. SUMMARY: Diagnostic thoracoscopy and sometimes therapeutic, assumes an important role in the etiology and symptoms relief of many patients with recurrent pleural effusions. It's a simple and well tolerable method, with high diagnostic yield, that contributes to an earlier intervention. It can control malignant and recurrent pleural effusions, which will have an important role in the treatment and quality of the patient's life. In spite of the number of complications being small and of lack of importance, we think that the use of thoracoscopy is to be decided in an Individual basis, weighting risks and benefits. The authors summarise the technique and methodology, their contraindications, complications and indications, reviewing some published results, emphasising the anaesthesia method and some information supporting local anaesthesia with pré-medication.

  6. Ant Colonies Do Not Trade-Off Reproduction against Maintenance.

    Directory of Open Access Journals (Sweden)

    Boris H Kramer

    Full Text Available The question on how individuals allocate resources into maintenance and reproduction is one of the central questions in life history theory. Yet, resource allocation into maintenance on the organismic level can only be measured indirectly. This is different in a social insect colony, a "superorganism" where workers represent the soma and the queen the germ line of the colony. Here, we investigate whether trade-offs exist between maintenance and reproduction on two levels of biological organization, queens and colonies, by following single-queen colonies of the ant Cardiocondyla obscurior throughout the entire lifespan of the queen. Our results show that maintenance and reproduction are positively correlated on the colony level, and we confirm results of an earlier study that found no trade-off on the individual (queen level. We attribute this unexpected outcome to the existence of a positive feedback loop where investment into maintenance (workers increases the rate of resource acquisition under laboratory conditions. Even though food was provided ad libitum, variation in productivity among the colonies suggests that resources can only be utilized and invested into additional maintenance and reproduction by the colony if enough workers are available. The resulting relationship between per-capita and colony productivity in our study fits well with other studies conducted in the field, where decreasing per-capita productivity and the leveling off of colony productivity have been linked to density dependent effects due to competition among colonies. This suggests that the absence of trade-offs in our laboratory study might also be prevalent under natural conditions, leading to a positive association of maintenance, (= growth and reproduction. In this respect, insect colonies resemble indeterminate growing organisms.

    2018-03-01

    If one of the major aspirations of postcolonial theory is to re-establish a balance in the relationship between the (former) colonizer and the colonized by engaging the voices of the "subaltern", and on the other hand to illuminate how power relations of the present are embedded in history (Mills 2007), we argue that important theoretical insights might inform research by anchoring post-colonial theory within a sociopsychological framework. While there is a growing corpus of sociopsychological research articles focusing on how major geopolitical events and historical processes bear on people's lives, we aim to investigate the theoretical potential of postcolonial theory within the disciplines aiming at a sociopsychological approach. By focusing on the social dynamics of power imbalances, post-colonial theory finds its operational meaning: the feelings stemming from actions committed in the past are indeed crucial in determining reparatory attitudes and policies towards members of former colonized groups. Firstly, drawing from the sociopsychological scientific production related to consequences of colonial past, seen in recent years as a growing research interest in the field, we will explore patterns and trends through a thematic analysis of literature. Social Psychology as well as adjacent disciplines can greatly benefit from this theoretical fertilization, especially in the way post-colonial ideologies relate to the symbolic promotion versus exclusion of indigenous culture (Sengupta et al., International Journal of Intercultural Relations, 36(4), 506-517, 2012). Furthermore, by comparing and contrasting the ideological cosmologies relating to this particular topic, this study aims to establish the state of knowledge in the field, to identify how research methods and thematic fields are paired, to find "gaps" and create spaces for research that become integrative of postcolonial theory. While focusing on academic production, we also hope to contribute to develop

    Full Text Available La coyuntura laboral reciente del desempleo en Colombia muestra que su componente cíclico se ha reducido a su mínima expresión y que, por ende, la mayor parte del desempleo actual hace referencia a las tipologías friccional y estructural del desempleo, y puede ser explicado en gran parte por el “mismatch” existente entre la demanda y la oferta de trabajo. La carencia de información sobre las necesidades y requerimientos del sector productivo ahondan y mantiene, aún más, las brechas existentes entre ambos componentes del mercado laboral. Dada esta situación, este trabajo propone una solución a la falta de información sobre los requerimientos cuantitativos y cualitativos de la demanda de trabajo, desde una metodología de big data, es decir, la aglomeración y sistematización de grandes cantidades de información, teniendo como fuente de información la utilizada por las bolsas de empleo colombianas en sus actividades de colocación. Procesada esta información, y luego comparada con la información de oferta laboral disponible en encuestas de hogares, puede concluirse que una base de vacantes construida a partir de big data en Colombia, es una excelente herramienta para conocer la demanda que, por distintas habilidades, tiene el sector productivo y, por ende, la formulación de políticas públicas integrales de educación y formación, sumamente requeridas en el país. Este artículo documenta el esfuerzo pionero desarrollado al respecto.

    Full Text Available The encomienda in Colonial Latin America was the initial grant that provided a conquistador the opportunity to reach economic success and social status. At the same time it contributed to economic diversification and integration of both businesses and investments. Behind a wealthy encomendero there was a family, that incorporated in a kindred, entailed a set of relationships among a number of persons, businesses and local institutions that helped to increase his economic activities and maintain social status. This study addresses a family of Peruvian conquistadors, looking at the influence of kinship, Iberian regional links, patronage, and clientelism to acquire wealth and status.

    La encomienda de indios fue, en Hispanoamérica colonial, la merced que posibilitó a un conquistador la oportunidad de alcanzar éxito económico y ascenso social, a la vez que contribuyó a la diversificación e integración de sus inversiones y empresas. Detrás de un encomendero acaudalado se movía una estructura familiar que, integrada en una parentela y vinculada en una cadena informal de relaciones personales, ligaba a los individuos, sus negocios e instituciones contribuyendo a incrementar las oportunidades económicas y mantener el status social. Este estudio ejemplifica el rol multifacético de los primeros conquistadores peruanos, observando la influencia que en la adquisición de su patrimonio y ascenso social tuvieron factores tales como el parentesco, regionalismo, patronazgo y cientelismo.

  8. The Sociocultural Significance of Court Institutions in Colonial Virginia

    Directory of Open Access Journals (Sweden)

    Pavel V. Vostrikov

    2017-09-01

    Full Text Available In this article the author examines the sociocultural significance of courts in colonial Virginia. Virginia was agrarian “tobacco” colony, where the settlements of urban type did not get proper development. In this connection, court days were very important occasions for social gatherings, when colonists not only might participate in court hearings, but became involved in various social interactions such as news exchange, business transactions, cockfighting, horse racing and attending taverns. If not found in rare towns court buildings weresituated at road junctions and other convenient places to be more easily accessible for inhabitants of the colony. The author also provides a glimpse into the issues of law and order, crime and punishment as well as the general state of the colonial system of justice. During the colonial period the differences between judicial, executive and legislative branches of government were not distinct yet and the institution of the county court had immense importance as it combined all the three types of power on a local level. The court of oyer and terminer dealt with criminal offences. The General court in Williamsburg, the colonial capital, was the main court in Virginia which considered the most crucial cases. The colonial legal system was initially based on English traditions and precedents but it was constantly modified largely due to the singularities of the colony such as abundance of free land and chattel slavery.

  11. The Colonial Situation: Complicities and Distinctions from the Surrealist Image

    Directory of Open Access Journals (Sweden)

    Pedro Pablo Gómez

    2011-05-01

    Full Text Available In this work, taking as baseline the thought of Aimé Césaire and Franz Fanon —keeping in mind the closeness of the Negritude movement with surrealism—, we propose to approach the modernity/coloniality problem, appealing to the denominated surrealist image of beauty. In the first part the colonial situation is approached, in the second the colonial situation from the logic of surrealist image, and in the third the possibility of a decolonial universal or pluriversal is raised. In general terms, exploring the existent link between the “surrealist image” and the colonial structure of modernity —that generates the denominated colonial situation—, we aspire to approach what could be a decolonial aesthetic that, as general problem, will be tackled in later works.

  12. Iridovirus and microsporidian linked to honey bee colony decline.

    Directory of Open Access Journals (Sweden)

    Jerry J Bromenshenk

    Full Text Available BACKGROUND: In 2010 Colony Collapse Disorder (CCD, again devastated honey bee colonies in the USA, indicating that the problem is neither diminishing nor has it been resolved. Many CCD investigations, using sensitive genome-based methods, have found small RNA bee viruses and the microsporidia, Nosema apis and N. ceranae in healthy and collapsing colonies alike with no single pathogen firmly linked to honey bee losses. METHODOLOGY/PRINCIPAL FINDINGS: We used Mass spectrometry-based proteomics (MSP to identify and quantify thousands of proteins from healthy and collapsing bee colonies. MSP revealed two unreported RNA viruses in North American honey bees, Varroa destructor-1 virus and Kakugo virus, and identified an invertebrate iridescent virus (IIV (Iridoviridae associated with CCD colonies. Prevalence of IIV significantly discriminated among strong, failing, and collapsed colonies. In addition, bees in failing colonies contained not only IIV, but also Nosema. Co-occurrence of these microbes consistently marked CCD in (1 bees from commercial apiaries sampled across the U.S. in 2006-2007, (2 bees sequentially sampled as the disorder progressed in an observation hive colony in 2008, and (3 bees from a recurrence of CCD in Florida in 2009. The pathogen pairing was not observed in samples from colonies with no history of CCD, namely bees from Australia and a large, non-migratory beekeeping business in Montana. Laboratory cage trials with a strain of IIV type 6 and Nosema ceranae confirmed that co-infection with these two pathogens was more lethal to bees than either pathogen alone. CONCLUSIONS/SIGNIFICANCE: These findings implicate co-infection by IIV and Nosema with honey bee colony decline, giving credence to older research pointing to IIV, interacting with Nosema and mites, as probable cause of bee losses in the USA, Europe, and Asia. We next need to characterize the IIV and Nosema that we detected and develop management practices to reduce honey

    In this work the development of a methodology is studied to evaluate the uncertainty in the results of CFD codes and is compatible with the VV-20 standard Standard for Verification and Validation in CFD and Heat Transfer {sup ,} developed by the Association of Mechanical Engineers ASME . Similarly, the alternatives are studied for obtaining existing uncertainty in the results to see which is the best choice from the point of view of implementation and time. We have developed two methods for calculating uncertainty of the results of a CFD code, the first method based on the use of techniques of Monte-Carlo for the propagation of uncertainty in this first method we think it is preferable to use the statistics of the order to determine the number of cases to execute the code, because this way we can always determine the confidence interval desired level of output quantities. The second type of method we have developed is based on non-intrusive polynomial chaos. (Author)

The concentrations calculation of {sup 75}As, {sup 202}Hg, {sup 208}Pb and {sup 60}Ni allowed to validate the reliability of the proposed methodology when comparing the concentrations obtained with the application of the same and the concentrations of the same elements reported for the Certified Reference Material (CRM) of particulate atmospheric material of an urban area (Nist 1648-a), the comparison showed that the proposed methodology is feasible for the determination of not only radionuclides, but also for these trace elements. Detection and quantification limits of the order of microns of ng L{sup -1} were reached, corroborating with this the acceptance of the proposed methodology. Concentrations of the radionuclides of interest for CRM could be calculated. The concentrations of the radionuclides found in white samples and of the reagents used in the processing of the aerosol filters indicated that the calculations found belong to or correspond to the calculations that are reflected in the background measurement. Concentrations of {sup 232}Th, {sup 234}U, {sup 235}U and {sup 238}U in aerosols of the Cuernavaca City, Morelos (Mexico) showed higher values than those established by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), however the concentration of the radioisotopes per unit volume are within the typical values reported for the northern hemisphere; the value of isotopic ratios greater than unity point to the influence of anthropogenic activities or environmental factors such as the direction of the wind or the imbalance of these radionuclides in the atmosphere.

  20. [Japan's Oriental medicine policy in colonial Korea].

    Science.gov (United States)

    Park, Yunjae

    2008-06-01

    During its colonization of Korea, the Japanese Empire used the Western medicine as a tool for advertising its advanced culture. However, the medical workforce available in Korea was insufficient. The Rule for Uisaeng (Oriental medicine practitioner) was an ordinance decreed in 1913 with a purpose of supplementing the medical workforce. As the Oriental medicine practitioners became official medical workforce, the Japanese Empire could mobilize them in a hygienic administration such as prevention of epidemics. The Uisaengs also tried to adapt themselves to the colonial environment by studying Western medicines. However, the distrust of the Japanese Empire in Oriental medicine continued until 1920s. Manchurian Incident in 1931 brought a change. As the relationship with China aggravated, the provision of medical herb became unstable and the Japanese Empire began to encourage using Oriental medical herb following the Movement for Improving Rural Region Economy. An attempt of the Japanese Empire to utilize the medical herb resulted in a plan to make the Oriental medical herb officinal. The goal was to organize and standardize the Oriental medical herb through a research by the Medical Herb Investigation Committee. However, the medical herb on the table was the one verified by the Western medicine. That is, it was not a traditional medical herb that uses the original theory of Oriental medicine. There was a minority opinion arguing that they should study the Oriental medicine itself. However, that argument was also based on the theory and principles of the Western medicine. Even though an attempt to make full use of Uisaengs expanded as the war continued, the major medical workforce that the Japanese Empire relied on was those trained in Western medicine. In other words, the Japanese Empire did not give a full credit to the Oriental medicine during the colonial era. During the colonization, Japanese Empire used Oriental medicine under the nominal reason of lack of medical

  3. Collective Memories of Portuguese Colonial Action in Africa: Representations of the Colonial Past among Mozambicans and Portuguese Youths

    Directory of Open Access Journals (Sweden)

    João Feijó

    2010-05-01

    Full Text Available Social representations of the colonization and decolonization processes among young people from a former European colonial power (Portugal and from an African ex-colony (Mozambique were investigated through surveys using open- and closed-ended questions about national history, focusing on the identity functions of collective memories. Hegemonic and contested representations were found of the most prominent events related to Portuguese colonization of Mozambique, arousing a range of collective emotions. A central place is occupied by memories of the Colonial War, which ended with the Carnation Revolution in Portugal and the subsequent independence of the Portuguese African colonies. Overall, the depiction of colonialism was more negative for Mozambican than for Portuguese participants. The violent effects of colonial action were very salient in Mozambican memories, which stressed the most oppressive aspects of the colonial period, associated with slave trade and brutal repression. On the Portuguese side, the idealization of the voyages of discovery persisted, obscuring the most violent effects of colonial expansion. However, collective memories of colonization of former colonizer and former colonized do not simply stand opposed. Both Mozambican and Portuguese participants reported ambivalent feelings towards the colonization process.

    Full Text Available Bat colonies were sampled in the city of Rosario to increase the understanding of bat ecology in urban areas of the southern cone of South America. Seven species were recorded, of which three are new records for Rosario. One representative colony was chosen for intensive ecological study. Approximately 64 000 Tadarida brasiliensis formed a maternity colony in the attic of an old building. Most of the bats were pregnant or lactating females and their young.. Adults arrive in the colony in mid-September and leave in February, no bats were present at this site from the beginning of March to mid-September. Births occur between mid-November and mid-December. Pups roosted in compact clusters in the nursery areas, spatially segregated from adults. Densities of these aggregations were 643 + 76 bats/m2 (p Con el objetivo de incrementar el conocimiento de la ecología de los murciélagos en áreas urbanas, se muestrearon colonias en la ciudad de Rosario.

    Swarm intelligence is a research area that models the population of the swarm based on natural computation. Artificial bee colony (ABC) algorithm is a swarm based metaheuristic algorithm introduced by Karaboga to optimize numerical problem. Pattern-SAT is a pattern reconstruction paradigm that utilized 2SAT logical rule in representing the behavior of the desired pattern. The information of the desired pattern in terms of 2SAT logic is embedded to Hopfield neural network (HNN-P2SAT) and the desired pattern is reconstructed during the retrieval phase. Since the performance of HNN-P2SAT in Pattern-SAT deteriorates when the number of 2SAT clause increased, newly improved ABC is used to reduce the computation burden during the learning phase of HNN-P2SAT (HNN-P2SATABC). The aim of this study is to investigate the performance of Pattern-SAT produced by ABC incorporated with HNN-P2SAT and compare it with conventional standalone HNN. The comparison is examined by using Microsoft Visual Basic C++ 2013 software. The detailed comparison in doing Pattern-SAT is discussed based on global Pattern-SAT, ratio of activated clauses and computation time. The result obtained from computer simulation indicates the beneficial features of HNN-P2SATABC in doing Pattern-SAT. This finding is expected to result in a significant implication on the choice of searching method used to do Pattern-SAT.

    Full Text Available The main objective of a production scheduling system is to assign tasks (orders or jobs to resources and sequence them as efficiently and economically (optimised as possible. Achieving this goal is a difficult task in complex environment where capacity is usually limited. In these scenarios, finding an optimal solution—if possible—demands a large amount of computer time. For this reason, in many cases, a good solution that is quickly found is preferred. In such situations, the use of metaheuristics is an appropriate strategy. In these last two decades, some out-of-the-shelf systems have been developed using such techniques. This paper presents and analyses the development of a shop-floor scheduling system that uses ant colony optimisation (ACO in a backward scheduling problem in a manufacturing scenario with single-stage processing, parallel resources, and flexible routings. This scenario was found in a large food industry where the corresponding author worked as consultant for more than a year. This work demonstrates the applicability of this artificial intelligence technique. In fact, ACO proved to be as efficient as branch-and-bound, however, executing much faster.

  10. Was Fundamental Education Another Form Of Colonialism?

    2007-01-01

    A description of the work of Pedro Tamesis Orata provides an opportunity to investigate the conflicts that can occur when educators seek to reduce poverty while trying to respect indigenous cultures. A native of the Philippines, Orata completed his doctoral studies at the Ohio State University in 1927. During US President Franklin Roosevelt's New Deal, he accepted the position of school principal for the US Bureau of Indian Affairs. After World War II, he directed the spread of fundamental education through the United Nations Educational, Scientific and Cultural Organization (UNESCO). In his final years, he returned to the Philippines where he began a movement to spread what were called self-help high schools. In these activities, Orata taught people to follow John Dewey's five steps of thinking while working to improve their standards of living. In the 1970s, educators, such as Paulo Freire, complained that problem-solving methods, similar to those Orata favored, reinforced the oppressive aspects of formerly colonial societies. While Freire may have been overly critical, conflicts among cultural orientations appear to be unavoidable. The hope behind this investigation is that the difficulties can be reduced when people understand the different forces that persist.

  16. Ecological conditions favoring budding in colonial organisms under environmental disturbance.

    Directory of Open Access Journals (Sweden)

    Mayuko Nakamaru

    Full Text Available Dispersal is a topic of great interest in ecology. Many organisms adopt one of two distinct dispersal tactics at reproduction: the production of small offspring that can disperse over long distances (such as seeds and spawned eggs, or budding. The latter is observed in some colonial organisms, such as clonal plants, corals and ants, in which (superorganisms split their body into components of relatively large size that disperse to a short distance. Contrary to the common dispersal viewpoint, short-dispersal colonial organisms often flourish even in environments with frequent disturbances. In this paper, we investigate the conditions that favor budding over long-distance dispersal of small offspring, focusing on the life history of the colony growth and the colony division ratio. These conditions are the relatively high mortality of very small colonies, logistic growth, the ability of dispersers to peacefully seek and settle unoccupied spaces, and small spatial scale of environmental disturbance. If these conditions hold, budding is advantageous even when environmental disturbance is frequent. These results suggest that the demography or life history of the colony underlies the behaviors of the colonial organisms.

  17. Morphodynamics of a growing microbial colony driven by cell death

    2017-11-01

    Bacterial cells can often self-organize into multicellular structures with complex spatiotemporal morphology. In this work, we study the spatiotemporal dynamics of a growing microbial colony in the presence of cell death. We present an individual-based model of nonmotile bacterial cells which grow and proliferate by consuming diffusing nutrients on a semisolid two-dimensional surface. The colony spreads by growth forces and sliding motility of cells and undergoes cell death followed by subsequent disintegration of the dead cells in the medium. We model cell death by considering two possible situations: In one of the cases, cell death occurs in response to the limitation of local nutrients, while the other case corresponds to an active death process, known as apoptotic or programmed cell death. We demonstrate how the colony morphology is influenced by the presence of cell death. Our results show that cell death facilitates transitions from roughly circular to highly branched structures at the periphery of an expanding colony. Interestingly, our results also reveal that for the colonies which are growing in higher initial nutrient concentrations, cell death occurs much earlier compared to the colonies which are growing in lower initial nutrient concentrations. This work provides new insights into the branched patterning of growing bacterial colonies as a consequence of complex interplay among the biochemical and mechanical effects.

    1972-01-01

    Concepts for expanding a 12-man lunar surface base to a more permanent colony of about 180 persons are studied. Guidelines for the colony design are that the colony must perform a useful function, and that design should maximize use of lunar materials and minimize requirements of resupply from the earth. The first use of lunar materials should be for oxygen production, to achieve which large electrical or thermal power inputs are necessary. Some of the efforts which should be directed toward food and plant growth are considered, and those factors from life support and waste control which bear further study are examined. Aspects of power generation, mining, and construction are discussed.

    Zhang, Bin; Jiang, Yi; Minsu Kim Collaboration

    Proteus Mirabilis colony exhibits striking spatiotemporal regularity, with concentric ring patterns with alternative high and low bacteria density in space, and periodicity for repetition process of growth and swarm in time. We present a simple mathematical model to explain the spatiotemporal regularity of P. Mirabilis colonies. We study a one-dimensional system. Using a reaction-diffusion model with thresholds in cell density and nutrient concentration, we recreated periodic growth and spread patterns, suggesting that the nutrient constraint and cell density regulation might be sufficient to explain the spatiotemporal periodicity in P. Mirabilis colonies. We further verify this result using a cell based model.

    Full Text Available Honey bees face numerous biotic threats from viruses to bacteria, fungi, protists, and mites. Here we describe a thorough analysis of microbes harbored by worker honey bees collected from field colonies in geographically distinct regions of Turkey. Turkey is one of the World’s most important centers of apiculture, harboring 5 subspecies of Apis mellifera L., approximately 20% of the honey bee subspecies in the world. We use deep ILLUMINA-based RNA sequencing to capture RNA species for the honey bee and a sampling of all non-endogenous species carried by bees. After trimming and mapping these reads to the honey bee genome, approximately 10% of the sequences (9-10 million reads per library remained. These were then mapped to a curated set of public sequences containing ca. 60 megabase-pairs of sequence representing known microbial species associated with honey bees. Levels of key honey bee pathogens were confirmed using quantitative PCR screens. We contrast microbial matches across different sites in Turkey, showing new country recordings of Lake Sinai virus, two Spiroplasma bacterium species, symbionts Candidatus Schmidhempelia bombi, Frischella perrara, Snodgrassella alvi, Gilliamella apicola, Lactobacillus spp., neogregarines, and a trypanosome species. By using metagenomic analysis, this study also reveals deep molecular evidence for the presence of bacterial pathogens (Melissococcus plutonius, Paenibacillus larvae, Varroa destructor-1 virus, Sacbrood virus, Apis filamentous virus and fungi. Despite this effort we did not detect KBV, SBPV, Tobacco ringspot virus, VdMLV (Varroa Macula like virus, Acarapis spp., Tropilaeleps spp. and Apocephalus (phorid fly. We discuss possible impacts of management practices and honey bee subspecies on microbial retinues. The described workflow and curated microbial database will be generally useful for microbial surveys of healthy and declining honey bees.

    Full Text Available Bees are very important for terrestrial ecosystems and, above all, for the subsistence of many crops, due to their ability to pollinate flowers. Currently, the honey bee populations are decreasing due to colony collapse disorder (CCD. The reasons for CCD are not fully known, and as a result, it is essential to obtain all possible information on the environmental conditions surrounding the beehives. On the other hand, it is important to carry out such information gathering as non-intrusively as possible to avoid modifying the bees’ work conditions and to obtain more reliable data. We designed a wireless-sensor networks meet these requirements. We designed a remote monitoring system (called WBee based on a hierarchical three-level model formed by the wireless node, a local data server, and a cloud data server. WBee is a low-cost, fully scalable, easily deployable system with regard to the number and types of sensors and the number of hives and their geographical distribution. WBee saves the data in each of the levels if there are failures in communication. In addition, the nodes include a backup battery, which allows for further data acquisition and storage in the event of a power outage. Unlike other systems that monitor a single point of a hive, the system we present monitors and stores the temperature and relative humidity of the beehive in three different spots. Additionally, the hive is continuously weighed on a weighing scale. Real-time weight measurement is an innovation in wireless beehive—monitoring systems. We designed an adaptation board to facilitate the connection of the sensors to the node. Through the Internet, researchers and beekeepers can access the cloud data server to find out the condition of their hives in real time.

    Full Text Available THE granulocyte colony-stimulating factor (G-CSF plays an important role in normal granulopoiesis. Its functions are mediated by specific receptors on the surface of responsive cells and, upon ligand binding, several cytoplasmic tyrosine kinases are activated. The cytoplasmic region proximal to the membrane of the G-CSF receptor (G-CSF-R transduces proliferative and survival signals, whereas the distal carboxy-terminal region transduces maturation signals and suppresses the receptor's proliferative signals. Mutations in the G-CSF-R gene resulting in truncation of the carboxy-terminal region have been detected in a subset of patients with severe congenital neutropenia who developed acute myelogenous leukemia (AML. In addition, the AML1-ETO fusion protein, expressed in leukemic cells harboring the t(8;21, disrupt the physiological function of transcription factors such as C/EBPα and C/EBPε, which in turn deregulate G-CSF-R expression. The resulting high levels of G-CSF-R and G-CSF-dependent cell proliferation may be associated with pathogenesis of AML with t(8;21. Moreover, in vitro and in vivo studies demonstrated that G-CSF may act as a co-stimulus augmenting the response of PML-RARα acute promyelocytic leukemia cells to all-trans-retinoic acid treatment. Finally, in the PLZF-RARα acute promyelocytic leukemia transgenic model, G-CSF deficiency suppressed leukemia development. Altogether, these data suggest that the G-CSF signaling pathway may play a role in leukemogenesis.

  7. Eutectic colony formation: A stability analysis

    Experiments have widely shown that a steady-state lamellar eutectic solidification front is destabilized on a scale much larger than the lamellar spacing by the rejection of a dilute ternary impurity and forms two-phase cells commonly referred to as ''eutectic colonies.'' We extend the stability analysis of Datye and Langer [V. Datye and J. S. Langer, Phys. Rev. B 24, 4155 (1981)] for a binary eutectic to include the effect of a ternary impurity. We find that the expressions for the critical onset velocity and morphological instability wavelength are analogous to those for the classic Mullins-Sekerka instability of a monophase planar interface, albeit with an effective surface tension that depends on the geometry of the lamellar interface and, nontrivially, on interlamellar diffusion. A qualitatively new aspect of this instability is the occurrence of oscillatory modes due to the interplay between the destabilizing effect of the ternary impurity and the dynamical feedback of the local change in lamellar spacing on the front motion. In a transient regime, these modes lead to the formation of large scale oscillatory microstructures for which there is recent experimental evidence in a transparent organic system. Moreover, it is shown that the eutectic front dynamics on a scale larger than the lamellar spacing can be formulated as an effective monophase interface free boundary problem with a modified Gibbs-Thomson condition that is coupled to a slow evolution equation for the lamellar spacing. This formulation provides additional physical insights into the nature of the instability and a simple means to calculate an approximate stability spectrum. Finally, we investigate the influence of the ternary impurity on a short wavelength oscillatory instability that is already present at off-eutectic compositions in binary eutectics.

  8. Transits of Venus and Colonial India

    Astronomical expeditions during the colonial period had a political and national significance also. Measuring the earth and mapping the sky were activities worthy of powerful and power- seeking nations. Such was the sanctity of global astronomical activity that many other agendas could be hidden under it. An early astronomy-related expedition turned out to be extremely beneficial, to botany. The expedition sent by the French Government in 1735 to South America under the leadership of Charles Marie de la Condamine (1701--1774) ostensibly for the measurement of an arc of the meridian at Quito in Ecuador surreptitiously collected data that enabled Linnaeus to describe the genus cinchona in 1742. When the pair of transits of Venus occurred in 1761 and 1769, France and England were engaged in a bitter rivalry for control of India. The observation of the transits became a part of the rivalry. A telescope presented by the British to a South Indian King as a decorative toy was borrowed back for actual use. Scientifically the transit observations were a wash out, but the exercise introduced Europe to details of living Indian tradition of eclipse calculations. More significantly, it led to the institutionalization of modern astronomy in India under the auspices of the English East India Company (1787). The transits of Venus of 1874 and 1882 were important not so much for the study of the events as for initiating systematic photography of the Sun. By this, Britain owned most of the world's sunshine, and was expected to help European solar physicists get data from its vast Empire on a regular basis. This and the then genuinely held belief that a study of the sun would help predict failure of monsoons led to the institutionalization of solar physics studies in India (1899). Of course, when the solar physicists learnt that solar activity did not quite determine rainfall in India, they forgot to inform the Government.

    Full Text Available Public health in twenty-first century Ghana is mired with several issues ranging from the inadequacy of public health facilities, improper settlement planning, insanitary conditions, and the inadequacy of laws and their implementation. This situation compared to the colonial era is a direct contradiction. Development in the pre-colonial era to the colonial era sought to make the prevention of diseases a priority in the colonial administration. This was begun with the establishment of the health branch in 1909 as a response to the bubonic plague that was fast spreading in the colony. From here public health policies and strategies were enacted to help the diseases prevention cause. Various public health boards, the medical research institute or the laboratory branch, the waste management department, the use of preventive medicine and maintenance of good settlement planning and sanitation were public health measures in the colonial era. This research seeks to analyse the public health system in the colonial era so as to draw basic lessons for twenty-first century Ghana. Archival data and other secondary sources are reviewed and analysed to help draw these lessons. Richard Rose’s lesson-drawing approach was used to draw the lessons.

    Full Text Available 10.12957/cadest.2009.15748Recentemente, a ABNT publicou um conjunto de normas nacionais a serem utilizadas na avaliação do desempenho de edificações de até cinco pavimentos ABNT NBR 15755. Dentre os vários critérios de avaliação, está o desempenho acústico das edificações, que deve atender a requisitos mínimos, considerando uma série de tópicos, entre eles: isolamento de ruídos aéreo. A partir do momento que essas normas entrarem em vigor, profissionais deverão estar capacitados para realizar medições nas edificações e surgirá uma nova discussão: Como os consumidores, potenciais proprietários de um imóvel, poderão comparar os resultados do desempenho de diferentes edificações fornecidos por diferentes profissionais? Quais são as incertezas destas medições? Esse artigo tem como objetivo estabelecer critérios para calcular, avaliar e comparar os valores de incerteza do resultado de medição do parâmetro de isolamento sonoro aéreo, Diferença padronizada de nível (DnT, obtidos através das metodologias propostas no Guia para Expressão da Incerteza de Medição (ISO/IEC GUIDE 98 . Precedendo a estimativa da incerteza de medição, foi estabelecida uma metodologia de validação do conjunto de medições, a fim de evidenciar sua confiabilidade metrológica. Esta metodologia de medição é composta por testes estatísticos, objetivando avaliar a homogeneidade entre médias e entre desvios padrão dos conjuntos de repetições das medições que originaram o resultado da medição.

    Full Text Available Resumo: Metodologias tradicionais para gerenciamento de projetos já não dão conta de projetos onde fatores como complexidade, riscos, restrições de recursos, prioridade de prazo, geração de valor para o negócio, alinhamento estratégico constituem-se em partes intrínsecas do problema gerencial. A ITIL surge como uma estrutura de referencial para a padronização tecnológica inteligente da área de tecnologia da informação. Grandes empresas globais e muitas empresas nos países emergentes estão adotando a ITIL para efetuar as mudanças em tecnologia da informação numa tentativa de colocar a área de tecnologia da informação a serviço negócio, estrategicamente alinha às diretrizes e prioridades de crescimento corporativo. Muitas empresas têm implantado a ITIL através dos pressupostos, ferramentas e técnicas da metodologia PRINCE2 para gerenciamento de projetos com sucesso. Este fato deve-se em muitos casos ao foco da estrutura conceitual PRINCE2 no alinhamento estratégico de TI aos objetivos do negócio e este fato coincide com um dos principais objetivos da ITIL e desta forma implantar a ITIL através do PRINCE2 tem sido uma estratégia assertiva e de sucesso. Demonstrar este vínculo dinâmico entre ambas as estruturas de conhecimento é um dos principais objetivos deste artigo.DOI:10.5585/gep.v4i2.143

  12. Hindu Responses to Darwinism: Assimilation and Rejection in a Colonial and Post-Colonial Context

    2010-06-01

    Hindu responses to Darwinism, like Christian, have run the gamut from outright rejection to fairly robust but limited accommodations of the Darwinian perspective. Despite certain features of Hindu thought such as the enormous time-scales of traditional cosmogonies that may suggest considerable affinity with modern notions of organic evolution, more often than not traditional assumptions have worked against deep engagement with Darwinism, allowing only for superficial assimilation at best. Three fundamental factors have affected Hindu responses to Darwinism: the great diversity within the tradition spanning evolutionist and creationist perspectives, the encounter with Darwinism in the late nineteenth century as part of an alien culture, and the fact that this encounter occurred within a colonial context. This essay explores the complex interactions of these three factors, beginning with the diversity within the ancient and classical cosmological traditions, followed by consideration of colonial developments and the emergence of four representative Hindu approaches to Darwinism: Modern Vedic Evolutionism, Anthropic Vedic Evolutionism, Reactionary Vedic Evolutionism, and Modern Vedic Creationism. The essay concludes by discussing various epistemological issues in the attempts of modern Hindu apologists to legitimize Vedic world views. These issues include the appeal to modern science to confirm traditional ideals and values, while simultaneously subordinating scientific method to spiritual means of knowledge, or rejecting scientific methodology with its inbuilt skepticism entirely.

    Full Text Available Indian forest based culture has a long history. Until the British colonial rule (1757 -1947, Indian forest has been controlled and used by several monarchies. The features of forest based livelihoods were also quite different from one period to another. Before Muslim period, Indian forest used to be considered as an important source of resource, but exploitation was quite less compared to total forest cover. People used to admire native forest for the role it used to play. However, during Muslim and early British period (East India Company period, 1757 – 1857 forest was considered only as the source of timber. To produce farmland a considerable amount of forest cover was also destroyed. After the handover of the colonial power (1857, the British government realised the importance of forests for revenue generation and implemented several rules and regulations to control the ‘illicit’ timber felling. This forest management strategy was followed even after independence (1947 until the JFM system was implemented.

    Full Text Available Durante la última década restauradores, artistas e investiga - dores en varias áreas de las ciencias sociales han trabajado co - lectivamente en la reconstrucción de los espacios de exhibición del Museo Colonial de Bogotá, y han convertido este lugar en una suerte de laboratorio de indagación sobre la cultura y la sociedad colonial en la Nueva Granada y en América. Cuando se recorren las diferentes salas del museo que fueron abiertas al público entre 2005 y 2012, es evidente cómo diferentes perspec - tivas historiográficas han influenciado la labor curatorial trans - formando la manera como las piezas se clasifican y exhiben. Así, es posible hacer un recorrido que va desde la iconografía hasta la antropología de la imagen, o también rastrear las tensiones que existen entre la historia social, la historia cultural y los es - tudios poscoloniales. Estos contrastes producen un interesante fenómeno: transformar el espacio de exhibición en un espacio de pensamiento. Partiendo de tal afirmación, esta conferencia tiene dos propósitos: el primero, consiste en presentar las diferentes perspectivas historiográficas que han influenciado la curaduría del museo durante los últimos años. El segundo, busca caracte - rizar la labor curatorial como un medio eficaz para criticar los diferentes tipos de discursos sobre el arte y la cultura colonial escritos en Colombia durante las últimas décadas.

    We investigate the role of deeply-rooted pre-colonial ethnic institutions in shaping comparative regional development within African countries. We combine information on the spatial distribution of ethnicities before colonization with regional variation in contemporary economic performance, as proxied by satellite images of light density at night. We document a strong association between pre-colonial ethnic political centralization and regional development. This pattern is not driven by differences in local geographic features or by other observable ethnic-specific cultural and economic variables. The strong positive association between pre-colonial political complexity and contemporary development obtains also within pairs of adjacent ethnic homelands with different legacies of pre-colonial political institutions.

    Valentina A Assenova

    Full Text Available European settler mortality has been proposed as an instrument to predict the causal effect of colonial institutions on differences in economic development. We examine the relationship between mortality, temperature, and economic development in former European colonies in Asia, Africa, and the Americas. We find that (i European settler mortality rates increased with regional temperatures and (ii economic output decreased with regional temperatures. Conditioning on the continent of settlement and accounting for colonies that were not independent as of 1900 undermines the causal effect of colonial institutions on comparative economic development. Our findings run counter to the institutions hypothesis of economic development, showing instead that geography affected both historic mortality rates and present-day economic output.

    Full Text Available A partir do final da década de 90, houve uma grande popularização do modelo de empresa conhecido como startup. As startups se diferenciaram por buscarem desenvolver produtos e serviços inovadores, mas contam com alto risco de falhar ao tentar atingir esse objetivo. Visto que os modelos tradicionais de administração não são considerados compatíveis com esse tipo de empresa, a metodologia Lean Startup propõe uma nova abordagem de trabalho para as startups alcançarem seu sucesso. Apesar de ser bastante difundida no meio empreendedor, esta metodologia é ainda pouco explorada academicamente. Portanto, o objetivo deste artigo é analisar a utilização do Lean Startup através de um estudo de caso no Superplayer, startup do ramo da tecnologia que usa a metodologia desde sua concepção. Como resultado do estudo foi possível descrever a utilização do Lean Startup e apontar vantagens e barreiras desta metodologia, gerando diretrizes que poderão auxiliar gestores e empreendedores que visam empregar a mesma em suas empresas.

    The deregulation and restructuring undergone by the electrical industry, as well as the tendency at world-wide level of reorganization in generation, transmission and distribution units has brought about, as a consequence, drastic changes in the operation of the electric power systems. The difficulties to construct new transmission power lines and the continuous increase in the electricity consumption are forcing more and more to operate the electric power systems every time nearer their safety limits. Nevertheless, to assure the system reliability without mattering what so plaintiff is the operating condition is a requirement that the electrical companies must satisfy. This panorama has motivated and impelled the use of new technologies for the critical indicators the monitoring that allow the electrical companies to guarantee the system safe operation. In this paper a methodology for the location of Fasorial Measurement Units, better known as FMU for the monitoring of the critical oscillation modes in the electric power systems is presented.

  20. Factors of honeybee colony performances on sunflower at apiary scale

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available An observatory of honeybee colonies (Apis mellifera, consisting of at least 200 colonies, divided into 10 apiaries of 20 colonies, was monitored for three years on sunflower honeyflow (2015–2017. The purpose of this observatory is to understand which factors control colony performance during sunflower honeyflow in south-western France. From the temporal dynamics of weight gain, statistical analysis reveals a hierarchy of factors. First, variability in apiary scale performance is an image of the effect of resource variability. But, in addition to this primordial factor, two other factors contribute very significantly to performance. On the one hand, the amount of capped brood and the number of bees at the time of the installation of the apiary: these two elements testify to the vitality of the colony. The second remarkable factor is the Varroa load, which strongly penalizes performance beyond a certain threshold. The negative effect of the Varroa load on the colony performance is minimized in case of abondant sunflower honey flow.

  1. Communication, Regulation and Control during Complex Patterning of Bacterial Colonies

    Science.gov (United States)

    Ben-Jacob, Eshel; Shochet, Ofer; Tenenbaum, Adam; Cohen, Inon; Czirók, Andras; Vicsek, Tamás.

    We present a study of interfacial pattern formation during growth of bacterial colonies. Growth of bacterial colony bears similarities to but presents an inherent additional level of complexity compared to non-living systems. In the former case, the building blocks themselves are living systems each with its own autonomous self-interest and internal degrees of freedom. At the same time, efficient adaptation of the colony to adverse growth conditions requires self-organization on all levels — which can be achieved only via cooperative behavior of the bacteria. To do so, the bacteria have developed sophisticated communication channels on all levels. Here we present a non-local communicating walkers model to study the effect of local bacterium-bacterium interaction and communication via chemotaxis signaling. We demonstrate how communication enables the colony to develop complex patterns in response to adverse growth conditions. Efficient response of the colony requires self-organization on all levels, which can be achieved only via cooperative behavior of the bacteria. It can be viewed as the action of an interplay between the micro-level (the individual bacterium) and the o-level (the colony) in the determination of the emerging pattern. Some qualitative features of the complex morphologies can be accounted for by invoking ideas from pattern formation in non-living systems together with a simplified model of chemotactic "feedback."

    Full Text Available Esse estudo questiona a suficiência dos aportes teóricos vinculados ao paradigma da complexidade para a emergência de uma metodologia complexa da aprendizagem e demais afazeres do campo da educação. Nossas hipóteses partem da convicção de que tais constructos dão conta dessas especificidades, potencializando o conhecer como um ser-agir em convivência. Procuramos demonstrar essa perspectiva, nesse texto, procedendo à descrição do funcionamento do Grupo de Ações e Investigações Autopoiéticas - GAIA, colocando-nos como sujeitos das ações de pesquisa, como observadores implicados no ato mesmo de observar, o que vincula este estudo às abordagensautopoiéticas e metacognitivas. O desafio é possibilitar, a partir de vivências dialógicas em ambientes complexos como as redes presenciais e virtuais de aprendizagens, novas compreensões acerca da inseparabilidade do conhecer-viver como fluxo passível de aplicação na educação. Articulando pesquisas de diferentes áreas do conhecimento, os pesquisadores envolvidos com o GAIA tendem a convergir na defesa de uma educação que se tece junto; que faz emergir o respeito mútuo, a amorosidade e também a morosidade necessária ao ser-agir na consciência de que cada organismo conspira para a vida com seu próprio ritmo e implicações cósmicas.

    O objetivo deste trabalho foi determinar o perfil físico-químico da aguardente de cana-de-açúcar produzida por diferentes metodologias de dupla destilação em alambique simples. Mosto fermentado de caldo de cana-deaçúcar foi destilado em alambique simples seguindo três metodologias de dupla destilação: a empregada para a produção de conhaque, a empregada na produção de uísque e a metodologia da proporção porcentual 10-80-10, referente aos volumes das frações “cabeça”, “coração” e “cauda” do destilado da segunda destilação. Para comparação, também foi produzida uma aguardente de cana-de-açúcar monodestilada. Os destilados foram analisados quimicamente quanto às concentrações de etanol, cobre, acidez volátil, furfural e hidroximetilfurfural, aldeídos, ésteres, metanol e álcoois superiores. As aguardentes de cana-de-açúcar foram também avaliadas sensorialmente quanto aos atributos de aroma, sabor e preferência. Comparada com a monodestilação, a dupla destilação melhorou a qualidade química das aguardentes, pois proporcionou redução das concentrações de cobre, de acidez volátil, de aldeídos, de ésteres, de metanol, de álcoois superiores e, consequentemente, do coeficiente de congêneres das aguardentes. As metodologias de dupla destilação baseadas na produção de conhaque e de uísque proporcionaram maior redução na concentração dos componentes secundários das aguardentes que a metodologia baseada na proporção 10-80-10. A dupla destilação melhorou também a qualidade sensorial das aguardentes, pois, independentemente da metodologia empregada, as aguardentes produzidas por dupla destilação obtiveram maior aceitação sensorial que a aguardente monodestilada. Dentre as aguardentes duplamente destiladas, a produzida segundo a metodologia do uísque obteve as maiores notas dos provadores quanto aos parâmetros de aroma e sabor e também foi a mais preferida.

  4. Multiple queens in founding colonies of the neotropical ant Pachycondyla striata Smith (Formicidae: Ponerinae).

    In social insects, the typical mode of colony foundation occurs when a single queen is inseminated by a male and establishes a new colony, although we can find interspecific and intraspecific variations in queen number and queen-mating frequencies in a single colony. This study aimed to verify the queen number in Pachycondyla striata (Smith) colonies and to evaluate the level of aggressiveness among workers. We collected 14 colonies of P. striata. The behaviors of individuals from five multiple-queen colonies maintained in laboratory were studied by the method of scan sampling. In order to evaluate aggressiveness, dyadic encounters among heterocolonial and homocolonial workers were performed. The results showed that colonies of P. striata can have two or more mated queens (polygynous colonies) besides to monogynous ones (colony containing one queen). Because in polygynous colonies the number of workers was relatively low, such colonies could represent colonies in the foundation phase that characterize a pleometrosis state. In fact, ovarian development analysis from queens showed that the number of queens in the colonies seemed to be unstable. Despite a few cases of oophagy (egg cannibalism), social hierarchy among queens is unclear in comparison to other Pachycondyla species. In addition, aggressiveness increased with distance among nests. Nearby colonies (less than 1 m apart) showed a low level of aggressiveness, suggesting the presence of polydomy, that is, a unique colony can occupy multiple nests. Polygyny associated to polydomy in founding colonies may confer benefits on growth and dispersion of colonies in the studied environments.

    Full Text Available Resumen La vida cotidiana en las haciendas coloniales implicó la introducción de una forma de administración de poblaciones impuesta sobre la sociedad indígena y regulada por las Leyes de Indias. En la zona norte de los Andes, el concertaje de indios y la abundancia de trabajos en la agricultura y en los obrajes fueron factores de atracción que generaron la tendencia a un crecimiento poblacional de larga duración. Más allá del debate inconcluso sobre la catástrofe demográfica en las Indias, este estudio investiga los perfiles y la incidencia de la mortalidad ordinaria y catastrófica como factor de regulación del crecimiento de la población en una parroquia de hacienda en la etapa final de los tiempos coloniales. La investigación se fundamenta en el vaciado nominal completo de libros de entierros incluidos en series de registros parroquiales. Los datos de la mortalidad analizados se extienden desde pocos años después de la fundación de la parroquia hasta 1857, momento de la supresión del tributo indígena, que se considera como año final de observación a pesar de la continuidad del registro. Las evidencias muestran una realidad marcada por una mortalidad de ciclo demográfico antiguo, dominada por el peso de las condiciones de vida adversas y el trabajo en la hacienda. Además, los datos permiten adentrarse en el universo de las rígidas clasificaciones sociales del mundo colonial.

El objetivo de este trabajo es obtener, a partir de unas necesidades básicas de financiación, su composición óptima para cada una de las CCAA de régimen común y para el gobierno central. La optimalidad de esta cesta se obtiene a partir de la minimización de la varianza de la cesta dado un determinado rendimiento impositivo (Markowitz, 1952 y garantizando, a la vez, la suficiencia financiera en el año base. Los resultados que obtenemos al aplicar tal metodología para el período 2002-07 muestran una relativa heterogeneidad entre las CCAA en la composición de la cesta óptima. Cuando del binomio rentabilidad-riesgo financiero se valoran ambos componentes, los impuestos preferidos son el impuesto sobre hidrocarburos, el impuesto sobre el alcohol y el impuesto sobre el tabaco. Dado que estos impuestos especiales no garantizan la suficiencia financiera, éstos se complementan con participaciones en el IVA y en el IRPF. En los casos extremos en que sólo se valora o bien el componente de riesgo o bien el de rentabilidad, respecto de tales participaciones complementarias, las CCAA prefieren el IVA y el IRPF, respectivamente.

    Endosymbiotic dinoflagellates in the genus Symbiodinium are fundamentally important to the biology of scleractinian corals, as well as to a variety of other marine organisms. The genus Symbiodinium is genetically and functionally diverse and the taxonomic nature of the union between Symbiodinium and corals is implicated as a key trait determining the environmental tolerance of the symbiosis. Surprisingly, the question of how Symbiodinium diversity partitions within a species across spatial scales of meters to kilometers has received little attention, but is important to understanding the intrinsic biological scope of a given coral population and adaptations to the local environment. Here we address this gap by describing the Symbiodinium ITS2 sequence assemblages recovered from colonies of the reef building coral Montipora capitata sampled across Kāne'ohe Bay, Hawai'i. A total of 52 corals were sampled in a nested design of Coral Colony(Site(Region)) reflecting spatial scales of meters to kilometers. A diversity of Symbiodinium ITS2 sequences was recovered with the majority of variance partitioning at the level of the Coral Colony. To confirm this result, the Symbiodinium ITS2 sequence diversity in six M. capitata colonies were analyzed in much greater depth with 35 to 55 clones per colony. The ITS2 sequences and quantitative composition recovered from these colonies varied significantly, indicating that each coral hosted a different assemblage of Symbiodinium. The diversity of Symbiodinium ITS2 sequence assemblages retrieved from individual colonies of M. capitata here highlights the problems inherent in interpreting multi-copy and intra-genomically variable molecular markers, and serves as a context for discussing the utility and biological relevance of assigning species names based on Symbiodinium ITS2 genotyping.

    Sylvatic plague (Yersinia pestis) is an exotic pathogen that is highly virulent in black-tailed prairie dogs (Cynomys ludovicianus) and causes widespread colony losses and individual mortality rates >95%. We investigated colony spatial characteristics that may influence inter-colony transmission of plague at 3 prairie dog colony complexes in the Great Plains. The 4 spatial characteristics we considered include: colony size, Euclidean distance to nearest neighboring colony, colony proximity index, and distance to nearest drainage (dispersal) corridor. We used multi-state mark-recapture models to determine the relationship between these colony characteristics and probability of plague transmission among prairie dog colonies. Annual mapping of colonies and mark-recapture analyses of disease dynamics in natural colonies led to 4 main results: 1) plague outbreaks exhibited high spatial and temporal variation, 2) the site of initiation of epizootic plague may have substantially influenced the subsequent inter-colony spread of plague, 3) the long-term effect of plague on individual colonies differed among sites because of how individuals and colonies were distributed, and 4) colony spatial characteristics were related to the probability of infection at all sites although the relative importance and direction of relationships varied among sites. Our findings suggest that conventional prairie dog conservation management strategies, including promoting large, highly connected colonies, may need to be altered in the presence of plague. ?? 2011 The Wildlife Society.

    Full Text Available Resumen A partir de la lectura de Piel negra, máscaras blancas, propongo en este artículo reflexionar sobre las ideas de Frantz Fanon a cerca de la enajenación del negro y del blanco en el sistema colonial. El objetivo es recuperar algunos de los principales aportes de Fanon para la comprensión del racismo colonial desde su teoría de la enajenación. Fanon presenta la enajenación como un paso previo a la esclavitud y al colonialismo, necesario para el mantenimiento de la explotación económica y analiza las conductas identitarias de "vergüenza de sí" como el resultado de la dominación colonial. Él describe con precisión el impacto del racismo y del colonialismo y sus efectos destructivos mostrando cómo los mecanismos de enajenación determinan la relación entre el blanco y el negro y cómo se reproducen las jerarquías que rigen estas relaciones. Retomar el pensamiento de Fanon y reconocer la pertinencia y actualidad de sus contribuciones es esencial para poder reubicar la lucha contra todas las formas de dominación en la continuación de la lucha contra el colonialismo en una época en que la identidad racial y el racismo han más que probado su capacidad de persistir en el tiempo y el espacio.

In it a descriptive argument is carried out based on theoretical findings on the relationships between extractivism, which is a proper practice of the colonial device, and what is here called colonization of nature. The article initially presents an assessment of the impact on the configuration of the ancestral vision and appropriation of the territory and its cultural contents, as a result of the imposition of a new semantics, in reference to the device of the colonial powers. Then, the relationship between extractivism and the process of colonization of nature is analyzed; to finally sketch a brief reflection, by linking contemporary issues and contexts. Este artículo de investigación pretende brindar elementos de análisis sobre el complejo tema de la colonización de la naturaleza. En él se hace una argumentación descriptiva basada hallazgos teóricos sobre las relaciones entre el extractivismo, una práctica propia del dispositivo colonial, y lo que aquí denominamos colonización de la naturaleza. El artículo presenta inicialmente un balance del impacto en la configuración de la visión-apropiación ancestral del territorio y su contenido cultural, a raíz de la imposición de una nueva semántica, en referencia al dispositivo de poder colonial. Luego, se analiza la relación del extractivismo con el proceso de colonización de la naturaleza, para finalmente esbozar una reflexión breve vinculando contextos y problemas contemporáneos.

    Full Text Available En 1979, tras una década de dictaduras militares, se inició la fase constitucional más larga en la historia del Ecuador. Ésta se levantó sobre las herencias del pasado y se caracterizó, de manera fundamental, por el tránsito desde un modelo estatal-desarrollista hacia uno de tipo empresarial, por el aparecimiento de nuevos agentes sociales, el multipartidismo político, la regionalización nacional, la presencia multicultural y la inserción del país en nuevas relaciones internacionales. Pero esos procesos trajeron como consecuencias centrales: la edificación de una economía inequitativa, una sociedad tensionada, la desestructuración institucional, la precarización del trabajo y la debilidad con la que la nación ha enfrentado el nuevo mundo unipolar. Todo ello ha configurado un cuadro de riesgos para la incipiente democracia. El Ecuador contemporáneo tiene, por tanto, una serie de desafíos económicos, sociales y políticos para escapar a la inestabilidad que ha acompañado a la construcción de su modernización democrática.___________________ABSTRACT:In 1979, after one decade of military dictatorships, the longest constitutional phase in the history of Ecuador was initiated. It was built upon the inheritance of the past and can be fundamentally characterized by the transition from a model that focused on the state as developing the economy (State-model to a model that focused on private business (enterprise-model. The appearance of new social agents, a multiparty system, national regionalization, multicultural presence and the country´s new international relationships are processes which show some important consequences: the establishment of an unequal economy, a society under tension, the breakdown of institutional structures, the vulnerability of working conditions and the weakness with which the nation faced the new polarized world. All this might put into danger this incipient democracy. And this is why Ecuador in these

    Full Text Available Como investigadores nos vemos enfrentados a una serie de dilemas que, si bien se relacionan con nuestro tema de estudio, nos colocan frente a situaciones conflictivas. Por un lado, el rápido desarrollo tecnológico que nos permite obtener información cada vez más específica y novedosa, a la vez que la difusión de nuestros resultados es más fácilmente accesible por colegas en diferentes partes del mundo a través de la digitalización y la informática. Así toda investigación, propia o foránea, está al alcance de un "click de mouse". Por otro, la concientización de que la muestra que trabajamos hoy es pasible de transformarse mañana en una nueva fuente de datos, no sólo nos alerta para su adecuado manejo si no también para su correcta conservación a fin de preservarla convenientemente para que en el futuro se puedan obtener nuevos datos. Esto es también un reto para nosotros como investigadores, aún cuando puedan llegar a contradecir nuestros resultados. Además, el hecho de la existencia de derechos -que a primera instancia parecerían contrapuestos- entre las diferentes partes que intervienen directa o indirectamente en una investigación antropológica, nos enfrenta a desafíos que exceden la meta científica. A esto se le suma la-por el momento-casi ausencia de protocolos que establezcan las pertinentes relaciones y responsabilidades entre nosotros-con derechos como investigadores-y las instituciones a las que pertenecemos. Así no encontramos en una encrucijada en la que se hace imperioso compatibilizar y ecualizar los derechos de las diferentes partes, sin descontar nuestra responsabilidad académica y científica a futuro.

  14. Food preparation in colonial America. A Bicentennial study.

    1976-07-01

    Both regional and national influences have pervaded America's culinary arts from colonial times until the present. In the South, for instance, indigenous foods, such as sweet potatoes--as well as an abundance of fruits and fowl--were commonly served. In the North, maple sirup was a New England product, as was codfish. Throughout the colonies, corn was easily grown and became a staple. Immigrants from the Old World brought their recipes to meld or adapt to conditions they met here. Recounted also is the unfolding of an American cuisine, especially in the southern colonies as it evolved from European food preparation practices. Cooking was done in great fireplaces, with equipment designed to fit. Meat was generally boiled or stewed in pots hung in the fireplace, although it might be slow-roasted on a hand-turned spit. Hot breads, the hallmark of southern cooking, date from colonial days. In the Noth, the Dutch farmer's wife developed real skill in using flour from home-grown wheat and rye, creating pancakes, waffles, doughnuts, crullers, and so on. After the first hard winter, food in New England became more plentiful. Boston brown bread was made from corn, wheat, or rye and probably sweetened with maple sirup. Imports of coffee, tea, and spices from the Orient and fruit from the tropics were later added to the cuisine. Colonial Americans understood well the art of food preparation and appreciated the taste of well prepared, well seasoned dishes.

    Full Text Available Creating Central Sulawesi: Mission Intervention, Colonialism and ‘Multiculturality’Central Sulawesi provides an example of how, under colonialism, non-state bodies contributed to the creation of new political identities in the Indonesian archipelago, and how the modern Indonesian state came to be based on these. Arguably, at the beginning of the twentieth century, the region was poised to be incorporated into the structure of one or other of the existing powerful Central and Southern Sulawesi political entities. As such, as just another ‘region’ in the sprawling archipelagic colony subjected to standard colonial policy, it should have been readily incorporated into the Indonesian state, albeit through the ‘Sulawesi Permesta’. Instead, in seeking to establish what one writer has described as a ‘volkskerk’ [people’s church], the ‘Poso mission’ established with colonial support by the Nederlandsche Zendinggenootschap [Netherlands Missionary Society] in 1892, was instrumental in defining new religious, cultural and linguistic boundaries. These acted to effectively isolate the Pamona people from adjacent Christian communities established by other missionary endeavours; from their Islamic neighbours and, arguably, from the ‘nation’. As elsewhere in the archipelago, the subsequent process of this region’s reintegration has formed part of the difficult postcolonial legacy inherited by the Indonesian nation.

    Full Text Available Mite mortality in two apiaries, one with 32 and the other with 15 honeybee (Apis mellifera carnica colonies, was recorded prior to and after flumethrin or fluvalinate treatments and after a control, oxalic-acid application. During the 42- and 51-day pre-treatment periods, the average daily natural mite drop was 0.04 (± 0.04 and 2.82 (± 2.19, respectively, which represents 1.09% (± 1.06 and 3.84% (± 3.04 of the total number of mites found during the experiment. The flumethrin or fluvalinate applications resulted in an average mite mortality at the two apiaries of 214.46 (± 260.02 and 4,098.64 (± 2,508.31. The treatments resulted in a 19.11% (± 14.62 and a 39.28% (± 10.47 reduction in the number of mites in slightly infested colonies and 94.30% (± 4.26 and 96.24% (± 3.14 in highly infested colonies. The difference in treatment efficacy between both apiaries was significant (P < 0.001 and indicates that fluvalinate and flumethrin are highly efficacious in dealing with highly infested honeybee colonies with sealed brood. The importance of effective mite control in colonies with a high level of natural mite mortality is discussed in this study.

    Full Text Available Mexican historiography concerning the presence of Africans and their descendents in Mexico has emphasized slaves and free-persons, but there has been little writing on analyzing the relationships between the owners of slaves and the slaves in everyday life. In the essay that follows, I discuss the relationship between the slave owners and the relationships that developed between slave owners and their slaves. My study will give emphasis to the formation of families, the interaction between the countryside and the city, conflicts and participation in the economy (fishing, mining and commercial ventures. Essentially, this is a family study, based on serial records from the local notary archives and other judicial sources. Although originally my analysis focuses on the relationships of the Busto family, I will only use this group as the analytical framework and as a unifying group of a wide region that includes the Altos de Jalisco, the Bajio of Guanajuato and Queretaro.//La historiografía mexicana relacionada con la presencia de africanos y sus descendientes en México ha puesto énfasis en los esclavos y en las personas libres pero ha dejado de lado el estudio de las relaciones entre los dueños y sus esclavos en la vida cotidiana.

Este estudio se concentrará en la formación de familias, en la interacción entre las ciudades y el campo, en los conflictos y la participación de la economía (pesca, minería y comercio. Esencialmente este es un estudio de la familia, basado en registros notariales. Aunque el análisis se centra en las relaciones de la familia Busto, este grupo se empleará sólo como un marco analítico y como unificador de una gran región que incluye los Altos de Jalisco, el Bajío de Guanajuato y Querétaro.

Neste trabalho, uma metodologia analítica para a determinação de cianeto em amostras de tiquira é proposta, empregando voltametria no modo pulso diferencial, após destilação da amostra em presença de ácido nítrico 0,1 mol.L-1. A metodologia desenvolvida foi comparada (teste t com um método padrão para a determinação de cianeto. Os resultados indicam que os métodos são equivalentes do ponto de vista estatístico, confirmando a viabilidade da metodologia proposta. As condições estabelecidas (volume da solução absorvedora = 100 mL; pH = 10; faixa de potencial = -0,5 a -0,1 V e velocidade de varredura = 20 mV.s-1 mostraram resultados reprodutíveis e permitiram a construção de curvas analíticas com valores de R da ordem de 0,999. O valor médio de cianeto encontrado em tiquira foi 2,8 x 10-5 mol.L-1 ± 2,4 x 10-6 mol.L-1, para n = 5, cerca de 150 vezes maior que o valor permitido para águas potáveis.Tiquira is an alcoholic beverage made of fermented and distilled manioc root (Manihot esculenta. The presence of toxic species such as carbamates, methanol, heavy metals and cyanide in this beverage is considered crucial to the quality of this important product of northern Brazil. This article proposes an analytical procedure involving the use of voltammetry in the differential mode after the sample is distilled in the presence of 0.1 mol.L-1 of nitric acid. The new methodology was compared (test T with a standard method for determining cyanide, indicating that the methods are equivalent from thee standpoint of statistics and thus confirming the viability of the proposed methodology.

  2. Parachemistries: Colonial chemopolitics in a zone of contest.

    Science.gov (United States)

    Mukharji, Projit Bihari

    2016-12-01

    The globalization of modern chemistry through European colonialism resulted, by the end of the nineteenth century, in the emergence of a number of parachemical knowledges. Parachemistries were bodies of non-European knowledge which came to be related to modern chemistry within particular historical milieux. Their relationship with modern chemistry was not necessarily epistemic and structural, but historical and performative. Actual historically located intellectuals posited their relationship. Such relationships were not merely abstract intellectual exercises; at a time when the practical uses of modern chemistry in statecraft were growing, the existence of these rival, competing parachemical knowledges challenged modern chemistry's regulatory deployments. Colonial locations emerged then not as mere 'contact zones', but as 'zones of conflict' where colonial chemopolitics was interrupted by the continued legitimacy and practice of parachemistries such as rasayana, kimiya, and neidan.

    Full Text Available This paper treats a tuning of PID controllers method using multiobjective ant colony optimization. The design objective was to apply the ant colony algorithm in the aim of tuning the optimum solution of the PID controllers (Kp, Ki, and Kd by minimizing the multiobjective function. The potential of using multiobjective ant algorithms is to identify the Pareto optimal solution. The other methods are applied to make comparisons between a classic approach based on the “Ziegler-Nichols” method and a metaheuristic approach based on the genetic algorithms. Simulation results demonstrate that the new tuning method using multiobjective ant colony optimization has a better control system performance compared with the classic approach and the genetic algorithms.

    Full Text Available Trichuris trichiura is a soil-transmitted helminth which is prevalent in warm, moist, tropical and subtropical regions of the world with poor sanitation. Heavy whipworm can result either in Trichuris dysenteric syndrome - especially in children - or in a chronic colitis. In heavy infections, worms can spread proximally and may cause ileitis. Here we provide first microscopic evidence for a T. trichiura adult worm embedded in the rectum of a post-Colonial Brazilian adult mummy. During Colonial and post-Colonial times, many European chroniclers described a parasitic disease named Maculo whose symptomatology coincides with heavy helminthiasis. Based on our findings and on comparison of ancient textual evidence with modern description of heavy whipworm, we feel confident in considering that the two syndromes are expressions of the same pathological condition.

    2016-06-01

    Full Text Available Examining J.H. Prynne’s 'Acrylic Tips' through a series of analogous readings, this paper identifies the location, characters, and themes of the poem. By examining the poem and the contiguities with 'Her Weasel’s Wild Returning', 'Acrylic Tips' is positioned against the historical decree of terra nullius over the sovereign land of Australia. The poem is read against and situated in the colonial and linguistic history of Australia. Read as a pastoral elegy, the poem depicts a hierarchy of human dominance over nature, which finds its ends in the colonial shearing shed, as well as the genetic laboratory. These positions are ultimately argued to be socio-political by-products of the colonial dominance of Indigenous culture and nature.

    2013-01-01

    Artificial neural networks, genetic algorithms and the ant colony optimization algorithm have become a highly effective tool for solving hard optimization problems. As their popularity has increased, applications of these algorithms have grown in more than equal measure. While many of the books available on these subjects only provide a cursory discussion of theory, the present book gives special emphasis to the theoretical background that is behind these algorithms and their applications. Moreover, this book introduces a novel real time control algorithm, that uses genetic algorithm and ant colony optimization algorithms for optimizing PID controller parameters. In general, the present book represents a solid survey on artificial neural networks, genetic algorithms and the ant colony optimization algorithm and introduces novel practical elements related to the application of these methods to  process system control.

    Full Text Available One of the actual elementary biologic principles of the introduction of queen is that the recipient co­lo­ny has to be queenless. We accidentally found that a queen can be accepted also in queenright co­lo­ny with using of the queen excluder. Therefore, we conducted two experiments with the introduction of queen in queenright colony.Under defined conditions of the experiment and with application of the queen excluder as a separator of queens we successfully introduced queen in the queenright colony. This result is discussed in relation to the general principle that a queen should be introduced only in a queenless colony. It is possible that there are some exceptions advert to the existence of some unknown biologic patterns in the honey bee biology and pheromones.

  13. The regulation of ant colony foraging activity without spatial information.

    Prabhakar, Balaji; Dektar, Katherine N; Gordon, Deborah M

    2012-01-01

    Many dynamical networks, such as the ones that produce the collective behavior of social insects, operate without any central control, instead arising from local interactions among individuals. A well-studied example is the formation of recruitment trails in ant colonies, but many ant species do not use pheromone trails. We present a model of the regulation of foraging by harvester ant (Pogonomyrmex barbatus) colonies. This species forages for scattered seeds that one ant can retrieve on its own, so there is no need for spatial information such as pheromone trails that lead ants to specific locations. Previous work shows that colony foraging activity, the rate at which ants go out to search individually for seeds, is regulated in response to current food availability throughout the colony's foraging area. Ants use the rate of brief antennal contacts inside the nest between foragers returning with food and outgoing foragers available to leave the nest on the next foraging trip. Here we present a feedback-based algorithm that captures the main features of data from field experiments in which the rate of returning foragers was manipulated. The algorithm draws on our finding that the distribution of intervals between successive ants returning to the nest is a Poisson process. We fitted the parameter that estimates the effect of each returning forager on the rate at which outgoing foragers leave the nest. We found that correlations between observed rates of returning foragers and simulated rates of outgoing foragers, using our model, were similar to those in the data. Our simple stochastic model shows how the regulation of ant colony foraging can operate without spatial information, describing a process at the level of individual ants that predicts the overall foraging activity of the colony.

In particular with the contemporary discourse in the Nordic countries on migrancy there is a tendency to see it as a phenomenon unfolding in a largely ahistorical space as a process of coming to terms...... with a new reality of multicultural society, as if there is no multicultural historical precedence in the Nordic countries, internally as well as externally through the Nordic countries participation in the project of colonialism....

  18. Redox signaling in the growth and development of colonial hydroids.

    Science.gov (United States)

    Blackstone, Neil W

    2003-02-01

    Redox signaling provides a quick and efficient mechanism for clonal or colonial organisms to adapt their growth and development to aspects of the environment, e.g. the food supply. A 'signature' of mitochondrial redox signaling, particularly as mediated by reactive oxygen species (ROS), can be elucidated by experimental manipulation of the electron transport chain. The major sites of ROS formation are found at NADH dehydrogenase of complex I and at the interface between coenzyme Q and complex III. Inhibitors of complex III should thus upregulate ROS from both sites; inhibitors of complex I should upregulate ROS from the first but not the second site, while uncouplers of oxidative phosphorylation should downregulate ROS from both sites. To investigate the possibility of such redox signaling, perturbations of colony growth and development were carried out using the hydroid Podocoryna carnea. Oxygen uptake of colonies was measured to determine comparable physiological doses of antimycin A(1) (an inhibitor of complex III), rotenone (an inhibitor of complex I) and carbonyl cyanide m-chlorophenylhydrazone (CCCP; an uncoupler of oxidative phosphorylation). Using these doses, clear effects on colony growth and development were obtained. Treatment with antimycin A(1) results in 'runner-like' colony growth, with widely spaced polyps and stolon branches, while treatment with CCCP results in 'sheet-like' growth, with closely spaced polyps and stolon branches. Parallel results have been obtained previously with azide, an inhibitor of complex IV, and dinitrophenol, another uncoupler of oxidative phosphorylation. Perhaps surprisingly, rotenone produced effects on colony development similar to those of CCCP. Assays of peroxides using 2',7'-dichlorofluorescin diacetate and fluorescent microscopy suggest a moderate difference in ROS formation between the antimycin and rotenone treatments. The second site of ROS formation (the interface between coenzyme Q and complex III) may thus

    Full Text Available Ant Colony Optimization (ACO is an optimization algorithm inspired by the behavior of real ant colonies to approximate the solutions of difficult optimization problems. In this paper, ACO is introduced to tackle the image edge detection problem. The proposed approach is based on the distribution of ants on an image; ants try to find possible edges by using a state transition function. Experimental results show that the proposed method compared to standard edge detectors is less sensitive to Gaussian noise and gives finer details and thinner edges when compared to earlier ant-based approaches.

    Fungal colonies are able to exhibit different morphologies depending on the environmental conditions. This allows them to cope with and adapt to external changes. When grown in solid or semisolid media the bulk of the colony is compact and several morphological transitions have been reported to occur as the external conditions are varied. Here we show how a unified simple mathematical model, which includes the effect of the accumulation of toxic metabolites, can account for the morphological changes observed. Our numerical results are in excellent agreement with experiments carried out with the fungus Aspergillus oryzae on solid agar.
