    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)

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.

    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 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.

    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.

Partiendo de la información inédita recopilada en el archivo del Monasterio de La Victoria de Santiago, se analizan aspectos históricos y musicales tales como la imagen de la monja música en la historiografía tradicional y postmoderna; su estatus social en el período colonial; la evolución de las plantillas musicales (instrumentistas y cantoras, con sus correspondientes cambios estilísticos y la injerencia que tenían los músicos ajenos al monasterio. Por último, se cuestiona la supuesta independencia de género de las monjas y se plantea la hipótesis de que las repetidas censuras a sus prácticas artístico-musicales estuvieron motivadas no sólo por propósitos moralizantes, sino también por la necesidad del clero secular y la autoridad civil de limitar el crecimiento de las instituciones monásticas.This is the first study about the musical practice in convents of Colonial Chile on the basis of new data collected in the archive of the convent of La Victoria in Santiago. It considers historical and musical aspects such as the image of the nun musician in traditional and postmodern historiography, her social status during the colonial period, the evolution of music groups (instrumentalists and singers, the stylistic changes associated with them, and the role played by foreign mule musicians in the monastery. Finally, it questions the assumption that nun musicians enjoyed an independence from masculine gender. Furthermore, it puts forward as a hypothesis that the frequent prohibitions of their musical and artistic practices originated not only in moralistic purposes, but also in the need of the secular clergy and civic authorities of limiting the growth of monastic institutions.

  19. Development and application of a methodology for the classification of the operating conditions of power transformers; Desarrollo y aplicacion de una metodologia para la clasificacion del estado operativo de transformadores de potencia

    2004-05-15

    This thesis work shows the development of a classification model that allows the user to assess the operative condition of power transformers. 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 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 El documento que se presenta a continuación tiene como objetivo informar sobre el aporte que hizo la Compañía de Jesús a la educación en Chile colonial, se proporcionará información de sus colegios, universidades, planes y métodos de estudios. La idea con esta exposición es establecer que, con la llegada de los jesuitas al país y con el inicio de las labores educativas, se instala en Chile, por primera vez, un sistema de enseñanza. La metodología que hemos empleado para este trabajo consiste en la revisión y recopilación de datos provenientes de diversos textos que son considerados clásicos en la materia, así como también de historias de la propia orden en el país, de manera que se pueda reunir toda la información que se necesita para reconstruir el panorama general de la educación jesuita en Chile. Como este tema ha sido escasamente abordado por la historiografía contemporánea nacional, este trabajo pretende ser un aporte a la historia de la educación en Chile y en América Latina, en el sentido en que la experiencia educativa jesuita en Chile fue similar a la que se experimentó en otras naciones del continente.

    Full Text Available Este artículo analiza la monopolización de la violencia en el ciclo inicial de colonización de Patagonia austral para lo cual propone, primero, que la precariedad local de los Estados de Argentina y Chile descansó en la fuerza expansiva de la industria ganadera para la instalación de su sobe- ranía territorial; y segundo, que la clausura de la delimitación fronteriza solo se produjo en el verano de 1922, como resultado de la represión a la insurgencia obrera. A partir de una extensa investigación en fuentes oficiales y empresariales referidas a Santa Cruz, Magallanes y Tierra del Fuego, así como en la prensa local, se investiga y compara la presencia de la fuerza policial y militar en las subdivisiones administrativas del extremo sur; además se examinaron similitudes y diferencias en las estra- tegias de control social.

    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.

La adaptación del instrumento, denominado Tabla de Informaciones, ha solicitado métodos cualitativos y cuantitativos de investigación en el intuito de simular un proceso real de elección. La tabla se ha mostrado adecuada a los propósitos del estudio, posibilitando la identificación de dos predeterminados principales de adquisición de informaciones: el primero con base en los atributos; el segundo basado en opciones de producto/servicio. Los datos apuntan aún para la utilización de una combinación de esas estrategias, de modo que la predominancia de cada una es influenciada por los objetivos de consumo.With the advance of technology, the use of mental shortcuts, to facilitate the selection of complex products with increasing numbers of attributes, is becoming evident in scientific literature. Improvement of a method, that allowed perception of these shortcuts at the point of sale, was the subject of this study. Studies that analyzed the assumptions influencing the constructive process of choice were taken as a reference. The relationship between acquisition and processing of information as well as the number of attributes that made up a final consumer choice was investigated. Validity of this improved method was tested in the context of mobile phones. Improvement of this method, The Information Table, involved qualitative and quantitative research to simulate a realistic process of choice. The Table was considered suitable for this study and disclosed two major patterns for acquisition of information. The first was based on attributes and the second was related to options of the product or service. Results also suggested use of a combination of these strategies, so that the predominance of each is influenced by the objectives of consumption.

    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

    2004-08-01

    Full Text Available Este artigo apresenta reflexões sobre o que significa fazer ciência no âmbito dos métodos e técnicas qualitativos da sociologia. Tem como pressupostos uma compreensão de metodologia como o conhecimento crítico dos caminhos do processo científico, que indaga e questiona acerca de seus limites e possibilidades; e o reconhecimento de que todo conhecimento sociológico tem, como fundamento, um compromisso com valores. A pesquisa qualitativa é definida como aquela que privilegia a análise de microprocessos, através do estudo das ações sociais individuais e grupais, realizando um exame intensivo dos dados, e caracterizada pela heterodoxia no momento da análise. Enfatiza-se a necessidade do exercício da intuição e da imaginação pelo so-ciólogo, num tipo de trabalho artesanal, visto não só como condição para o aprofundamento da análise, mas também - o que é muito importante - para a liberdade do intelectual. Discutem-se as principais críticas feitas à pesquisa qualitativa, em especial as acusações de falta de representatividade e de possibilidades de generalização; de subjetividade, decorrente da proximidade entre pesquisador e pesquisados; e o caráter descritivo e narrativo de seus resultados. Neste contexto, reflete-se sobre os problemas éticos envolvidos nesse tipo de pesquisa, e retoma-se brevemente a história que culminou com o predomínio do enfoque quantitativo, especialmente na sociologia norte-americana do pós-guerra. Em conclusão, o texto propõe que hoje o mais importante é produzir um conhecimento que, além de útil, seja explicitamente orientado por um projeto ético visando a solidariedade, a harmonia e a criatividade.This article presents considerations about what it means to do science within the context of qualitative methods and techniques in sociology.

    This paper is a proposal for the systematization of the process of bioclimatic design, particularly in its analytical stage. 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 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.

    Full Text Available GIS methodology to assess landslide susceptibility: application to a river catchment of central ItalyThis paper illustrates a GIS supported methodology for the assessment of landslide susceptibility. The methodology involves four steps: survey, site analysis, macro-area analysis, and susceptibility analysis. Statiscal and GIS processing of basical large scale geological dataset leads to the recognition of discriminating parameters (land conditions necessary but not sufficient to trigger landslides and predisposing factors (conditions that worsen slope stability separately for each landslides types. The susceptibility function combines GIS data to draw landslide susceptibility maps. These results represent the preliminary step for the assessment of landslide hazard and risk.

    Full Text Available Métodos sensoriais descritivos são de grande importância na indústria de alimentos para definir a qualidade sensorial de um produto. A análise descritiva quantitativa (ADQ é um método muito usado para identificar e quantficar os atributos sensoriais de alimentos. As etapas para realização da ADQ são: recrutamento e pré-seleção dos candidatos à julgadores, levantamento e descrição dos atributos, treinamento e seleção final dos julgadores e avaliação dos produtos. Visto que a ADQ requer treinamento longo dos julgadores, uma nova metodologia descritiva por ordenação (ADO foi desenvolvida recentemente , na qual algumas etapas são semelhantes à ADQ, porém o treinamento e a seleção final dos julgadores não acontecem e a avaliação dos produtos é realizada por ordenação da intensidade dos atributos, sendo a ADO um método mais econômico e rápido. O presente trabalho comparou a nova metodologia descritiva (ADO com o método tradicionalmente utilizado, a ADQ, por meio da descrição sensorial de quatro marcas de requeijão cremoso. Os atributos que caracterizaram os produtos foram: cor, aroma e sabor característicos, gosto doce, gosto salgado, sabor de ranço, consistência e viscosidade. Observou-se correlação significativa (p<0,05 entre as metodologias para 62,5% dos atributos avaliados. Assim, quando o objetivo é identificar diferenças sensoriais mais acentuadas a ADO pode ser usada em substituição a ADQ.

    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.

    This project entailed studying the cellulose in paper, the ink, colorants, and other materials used to produce American colonial currency. The technique primarily used in this project was X-Ray Fluorescence Spectroscopy (XRF). XRF mapping was used to provide both elemental analysis of large-scale objects as well as microscopic examination of individual pigment particles in ink, in addition to the inorganic additives used to prepare paper. The combination of elemental mapping with Fourier Transform Infrared (FTIR) and Raman Spectroscopies permits an efficient analysis of the currency. These spectroscopic methods help identify the molecular composition of the pigments. This combination of atomic and molecular analytical techniques provided an in-depth characterization of the paper currency on the macro, micro, and molecular levels. We have identified several of pigments that were used in the preparation of inks and colorants. Also, different inorganic crystals, such as alumina-silicates, have been detected in different papers. The FTIR spectroscopy allowed us to determine the type of cellulose fiber used in the production of paper currency. Our future research will be directed toward revealing important historical relationships between currencies printed throughout the colonies. ISLA Da Vinci Grant.

  17. 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

    Zhu, Minhui; Martini, K. Michael; Kim, Neil H.; Sherer, Nicholas; Lee, Jia Gloria; Kuhlman, Thomas; Goldenfeld, Nigel

    Experiments on nutrient-limited E. coli colonies, growing on agar gel from single cells reveal a power-law distribution of sizes, both during the growth process and in the final stage when growth has ceased. We developed a Python simulation to study the growth mechanism of the bacterial population and thus understand the broad details of the experimental findings. The simulation takes into account nutrient uptake, metabolic function, growth and cell division. Bacteria are modeled in two dimensions as hard circle-capped cylinders with steric interactions and elastic stress dependent growth characteristics. Nutrient is able to diffuse within and between the colonies. The mechanism of microbial colony growth involves reproduction of cells within the colonies and the merging of different colonies. We report results on the dynamic scaling laws and final state size distribution, that capture in semi-quantitative detail the trends observed in experiment. Supported by NSF Grant 0822613.

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

    Science.gov (United States)

    Tarpy, David R.; vanEngelsdorp, Dennis; Pettis, Jeffrey S.

    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.

    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.

  7. 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.

    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.

    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

    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.

    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. PMID:17015336

  15. 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.

    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.

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.

    2016-03-01

    Artificial bee colony (ABC) optimisation algorithm is a recent, fast and easy-to-implement population-based meta heuristic for optimisation. ABC has been proved a rival algorithm with some popular swarm intelligence-based algorithms such as particle swarm optimisation, firefly algorithm and ant colony optimisation. The solution search equation of ABC is influenced by a random quantity which helps its search process in exploration at the cost of exploitation. In order to find a fast convergent behaviour of ABC while exploitation capability is maintained, in this paper basic ABC is modified in two ways. First, to improve exploitation capability, two local search strategies, namely classical unidimensional local search and levy flight random walk-based local search are incorporated with ABC. Furthermore, a new solution search strategy, namely stochastic diffusion scout search is proposed and incorporated into the scout bee phase to provide more chance to abandon solution to improve itself. Efficiency of the proposed algorithm is tested on 20 benchmark test functions of different complexities and characteristics. Results are very promising and they prove it to be a competitive algorithm in the field of swarm intelligence-based algorithms.

Mansilla. Encontramos, en los escritos de los tres, signos que nos permiten percibir una comprensión similar (aunque no la misma de lo que entienden por herencia colonial. En los tres casos, esa herencia es vista de forma peyorativa, es decir, como un rasgo que habría que poner de lado y finalmente erradicar. A partir de un análisis textual tratamos de comprender en qué consiste ese concepto o ese remanente colonial en estos tres autores. Una vez que logramos averiguar a qué se podrían referir estos autores cuando manejan la idea de una herencia colonial, analizamos y cuestionamos estas ideas a partir de la concepción que la teoría mimética tiene de conceptos similares. En otras palabras, buscamos traducir los conceptos de los pensadores bolivianos en términos de la teoría mimética, ya sea para comprenderlos mejor, ya sea para verificar si tienen una significación en el contexto de esa teoría.

    Full Text Available O presente artigo discute a existência de uma metodologia jurídica no Mercosul, um bloco econômico intergovernamental, tendo por base a elogiável experiência supranacional, desenvolvida na União Europeia. Explorado é o fato de acreditar-se ser adequado o Mercosul restringir-se, no presente momento e estágio da integração, ao seu modelo original. Para tanto, em um primeiro momento, observa-se qual é o direito que o Mercosul tem, depois, quais são as características do direito da União Europeia, bem como a existência de uma verdadeira metodologia jurídica europeia, tudo isso com o propósito de ser, ao seu final, proposta a construção de uma metodologia jurídica mercosulista. É necessário admitir que ainda muito dela não existe, mas isso não quer dizer que a europeia possa ou deva ser transferida para o Mercosul.

    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?”

Se puede atribuir este hecho a su difícil clasificación, así como también a la falta de ediciones críticas de ese corpus todavía incompleto de la narrativa colonial.1   Al mismo tiempo que se destáca la carencia de estudios críticos, debería manifestarse que con motivo del quinto centenario de la gesta del descubrimiento, el acercamiento a estos albores narrativos se ha convertido en tema obligado para seminarios, encuentros, congresos. Y, gracias a la celebración, ya se ha publicado un buen número de obras que tratan de explicar y profundizar en esta productividad textual que gira sobre un doble eje: a lo narrativo histórico con énfasis en la referencialidad y b lo narrativo literario enfocado hacia la producción de la ficcionalidad.

    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.

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......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...... 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...

    Full Text Available This essay explores connections between post-colonial theory and action research. Post-colonial theory is committed to addressing the plague of colonialism. Action research, at its core, promises to problematize uncontested ‘colonial’ hegemonies of any form. Both post-colonial theory and action research engage dialogic, critically reflective and collaborative values to offer a fuller range of human wisdom. The authors contend that post-colonialism theory calls for justice and seeks to speak to social and psychological suffering, exploitation, violence and enslavement done to the powerless victims of colonization around the world by challenging the superiority of dominant perspectives and seeking to re-position and empower the marginalized and subordinated. In similar ways, action research works to eradicate oppression, powerlessness and worthlessness by affirming solidarity with the oppressed, helping humans move from passive to active and by fundamentally reshaping power. Because both post-colonial theory and action research position the insider or oppressed in an ethic of efficacy, it values community, relationships, communication and equality, and is committed to reciprocity, reflexivity and reflection. Thus, both hold the potential to help reconstruct conditions for a more democratic and just society

    Directory of Open Access Journals (Sweden)

    Del Nero Ulisses

    2002-01-01

    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.

    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

  3. 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.

  4. Colony collapse disorder: a descriptive study.

    Full Text Available 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.

  9. Early Developmental Program Shapes Colony Morphology in Bacteria

    Directory of Open Access Journals (Sweden)

    Gideon Mamou

    2016-03-01

    Full Text Available When grown on a solid surface, bacteria form highly organized colonies, yet little is known about the earliest stages of colony establishment. Following Bacillus subtilis colony development from a single progenitor cell, a sequence of highly ordered spatiotemporal events was revealed. Colony was initiated by the formation of leading-cell chains, deriving from the colony center and extending in multiple directions, typically in a “Y-shaped” structure. By eradicating particular cells during these early stages, we could influence the shape of the resulting colony and demonstrate that Y-arm extension defines colony size. A mutant in ymdB encoding a phosphodiesterase displayed unordered developmental patterns, indicating a role in guiding these initial events. Finally, we provide evidence that intercellular nanotubes contribute to proper colony formation. In summary, we reveal a “construction plan” for building a colony and provide the initial molecular basis for this process.

    2016-01-01

    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.

  15. 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.

    The moral modality of colonial power is still with us when it comes to the recreation of sexual norms of traditional or feudal society. We can examine the emergent properties of colonial knowledge anew by exploring how the colonial regime's strategic attention of regulating brothels in India differed from the analytic of power Foucault described for sexuality in European society. It turns out that amongst other things, public anxieties about the failure of adaptation by South Asians are incapable of leaving sexuality aside as a key interpretive device for their culture. The British preoccupation with reproducing the dynamics of the bourgeois matrimonial market on foreign soil in the mid-nineteenth century similarly necessitated a sociological pretext for racial purity. However, the kind of knowledge a typical traveller and employee of the East India Company brought to the Victorian public from his own researches in the brothels and streets of colonial India, which revealed how popular prostitution was as a vice amongst the officer class, was also more than a welcome imaginary relief from Christian morality; it was an alternative vision of modernity. © London School of Economics and Political Science 2012.

    Bacterial colonies often exhibit complex spatio-temporal organization. This collective behavior is affected by a multitude of factors ranging from the properties of individual cells (shape, motility, membrane structure) to chemotaxis and other means of cell-cell communication. One of the important but often overlooked mechanisms of spatio-temporal organization is direct mechanical contact among cells in dense colonies such as biofilms. While in natural habitats all these different mechanisms and factors act in concert, one can use laboratory cell cultures to study certain mechanisms in isolation. Recent work demonstrated that growth and ensuing expansion flow of rod-like bacteria Escherichia coli in confined environments leads to orientation of cells along the flow direction and thus to ordering of cells. However, the cell orientational ordering remained imperfect. In this paper we study one mechanism responsible for the persistence of disorder in growing cell populations. We demonstrate experimentally that a growing colony of nematically ordered cells is prone to the buckling instability. Our theoretical analysis and discrete-element simulations suggest that the nature of this instability is related to the anisotropy of the stress tensor in the ordered cell colony.

    Summarizing his colonial nesting waterbird survey experiences along the northern coast of the Gulf of Mexico in a paper presented to the Colonial Waterbird Group of the Waterbird Society (Portnoy 1978), bird biologist John W. Portnoy stated, “This huge concentration of nesting waterbirds, restricted almost entirely to the wetlands and estuaries of southern Louisiana, is unmatched in all of North America; for example, a 1975 inventory of wading birds along the Atlantic Coast from Maine to Florida [Custer and Osborn, in press], tallied 250,000 breeding [waterbirds] of 14 species, in contrast with the 650,000 birds of 15 species just from Sabine Pass to Mobile Bay.” The “650,000 birds” to which Portnoy referred, were tallied by him in a 1976 survey of coastal Louisiana, Mississippi, and Alabama (see below, under “Major Surveys” section). According to the National Atlas of Coastal Waterbird Colonies in the Contiguous United States: 1976-82 (Spendelow and Patton 1988), the percentages of the total U.S. populations of Laughing Gull (11%), Forster's Tern (52%), Royal Tern (16%), Sandwich Tern (77%), and Black Skimmer (44%) which annually nest in Louisiana are significant – perhaps crucially so in the cases of Forster's Tern, Sandwich Tern, and Black Skimmer. Nearly three decades after Spendelow and Patton's determinations above, coastal Louisiana still stands out as the major center of colonial wading bird and seabird nesting in all of the United States.

    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.

  13. 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.

    2010-03-01

    Full Text Available This article reviews how colonial rule and African actions during the colonial period affected the resources and institutional settings for subsequent economic development south of the Sahara. The issue is seen from the perspective of the dynamics of development in what was in 1900 an overwhelmingly land-abundant region characterised by shortages of labour and capital, by perhaps surprisingly extensive indigenous market activities and by varying but often low levels of political centralisation. The differential impact of French and British rule is explored, but it is argued that a bigger determinant of the differential evolution of poverty, welfare and structural change was the contrast between “settler” and “peasant” economies.

  8. Teaching South Asia beyond Colonial Boundaries

    Brian Caton

    2014-06-01

    Full Text Available Because of the methodological innovations of Subaltern Studies in the 1980s and 1990s, most historians’ familiarity with South Asian history is limited to the colonial or modern period. While the subalternist view is undoubtedly useful, it does not provide much help in thinking about what came before or after the colonial period. This limited context may prove to be a problem for a non-specialist constructing a full course in South Asian history or adding South Asia content to a course that seeks to break down area studies or nation-state boundaries. This article provides a starting point for such an enterprise. It reviews the South Asian history textbooks available in the market and identifies some of the scholarship that would suit courses or units organized by theme or by a larger Asian geography. It also reviews some of the collections of primary sources that could be used in such coursework.

  9. Morphology offers no clues to asexual vs. sexual origin of small Acropora cervicornis (Scleractinia: Acroporidae colonies

    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.

  11. 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.

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.

  13. Colony stimulating factors and their clinical implication

    International Nuclear Information System (INIS)

    Asano, Shigetaka

    1989-01-01

    Granulocytes and macrophage are dependent for their production and/or functional activation in vitro on the presence of a family of glycoproteins. They are generally called colony-stimulating factors (CSFs) because of their capacity to stimulate colony formation in semi-solid cultures, and are currently classified into four distinct subtypes, that is, Multi-CSF, GM-CSF, G-CSF and M-CSF, according to the cell type of colonies formed under their stimulation or their target cell specificity. All of the murine and human CSF subtypes and the genes for them have become available in a purified form and in a large scale, and now allow us to investigate their interactions, the mechanisms for their actions, the cell-cell interactions leading to their production and secretion, and their actions in vivo. Furthermore, the preclinical and/or clinical studies which were carried out using the purified CSFs strongly indicate that human CSFs will be effective strategies for preventing and treating opportunistic bacterial and fungal infection as a major cause of death in granulocytopenic patients.

    Full Text Available Spain’s colonial problem on the eve of the Cuban War of Independence was a deeply debated subject at the time in the Athenaeum of Madrid, like in Parliament. The author's argument is that, rather than sponsoring a scientific debate on the matter, the Athenaeum wanted to influence Spain’s public opinion and political élite of its own ideas on colonial reform.

    El problema colonial fue un tema debatido en profundidad en el Ateneo de Madrid en los momentos previos a la definitiva Guerra de Independencia Cubana (1895-1898. La idea que se defiende es que más que tener lugar un debate científico sobre el problema colonial contemporáneo, se trataba de aprovechar la plataforma ateneísta para concienciar a la opinión pública y la élite política española de la necesidad de una reforma colonial que por las mismas fechas se discutía en el Parlamento.

    1996-08-01

    Morphological changes of colonies have been investigatedfor a bacterial strain of Proteus mirabilis, which is a famous speciesfor producing concentric-ring-like colonies. It was found that colony patterns can be classified into three types,i.e., cyclic spreading, diffusion-limited growth (DLA-like)and three-dimensional growth (inside the agar medium) patterns. Cyclic spreading patterns can further be classifiedinto three subgroups, i.e., concentric-ring, homogeneous and spatiotemporal patterns. These subgroups were classified by examining the development of colony structure after colonies spread all over petri-dishes. Comparison of the results with thoseof another bacterial species Bacillus subtilis is also discussed.

    Who needs to go to outer space to study alien beings when the oceans of our own planet abound with bizarre and unknown creatures? Many of them belong to sessile clonal and colonial groups, including sponges, hydroids, corals, octocorals, ascidians, bryozoans, and some polychaetes. Their life histories, in many ways unlike our own, are a challenge for biologists. Studying their ecology, behavior, and taxonomy means trying to “think like a colony” to understand the factors important in their lives. Until the 1980s, most marine ecologists ignored these difficult modular organisms. Plant ecologists showed them ways to deal with the two levels of asexually produced modules and genetic individuals, leading to a surge in research on the ecology of clonal and colonial marine invertebrates. Bryozoans make excellent model colonial animals. Their life histories range from ephemeral to perennial. Aspects of their lives such as growth, reproduction, partial mortality due to predation or fouling, and the behavior of both autozooids and polymorphs can be studied at the level of the colony, as well as that of the individual module, in living colonies and over time.

    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.

    Colony counting in many colony experiments is detected by manual method at present, therefore it is difficult for man to execute the method quickly and accurately .A new automatic colony counting system was developed. Making use of image-processing technology, a study was made on the feasibility of distinguishing objectively white bacterial colonies from clear plates according to the RGB color theory. An optimal chromatic value was obtained based upon a lot of experiments on the distribution of the chromatic value. It has been proved that the method greatly improves the accuracy and efficiency of the colony counting and the counting result is not affected by using inoculation, shape or size of the colony. It is revealed that automatic detection of colony quantity using image-processing technology could be an effective way.

    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...

  1. Pollen foraging in colonies of Melipona bicolor (Apidae, Meliponini): effects of season, colony size and queen number.

    Hilário, S D; Imperatriz-Fonseca, V L

    2009-01-01

    We evaluated the ratio between the number of pollen foragers and the total number of bees entering colonies of Melipona bicolor, a facultative polygynous species of stingless bees. The variables considered in our analysis were: seasonality, colony size and the number of physogastric queens in each colony. The pollen forager ratios varied significantly between seasons; the ratio was higher in winter than in summer. However, colony size and number of queens per colony had no significant effect. We conclude that seasonal differences in pollen harvest are related to the production of sexuals and to the number of individuals and their body size.

    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.

    Full Text Available Ciclistas tem dificuldade de carregar compras e objetos pessoais. A maioria dos modelos atuais de bicicleta não contemplam soluções satisfatórias. Além disso, percebe-se a proximidade entre indivíduos que praticam o ciclismo e hábitos voltados à sustentabilidade. Sendo assim, uma solução que contribua para o transporte de compras pelos ciclistas, bem como contemple características sustentáveis, se mostra conveniente e bem vinda por esse público. O objetivo deste estudo, portanto, foi pesquisar e desenvolver uma metodologia para o projeto de um produto adaptado aos modelos atuais de bicicleta que consiga transportar as compras de maneira segura e confortável, que atenda aos padrões estéticos e comportamentais dos usuários e, ainda, que seja orientado aos preceitos da sustentabilidade, sendo este fabricável em escala industrial. Para tanto, foi pesquisado características do público alvo, modelos existentes de objetos de transporte para bicicletas, soluções de encaixe, entre outros. Com intuito de alinhar o produto ao viés da sustentabilidade, foi utilizado um checklist de verificação (SDO, 2013. O resultado foi um produto leve, lavável, adaptável à bicicleta, impermeável e versátil.

  9. Islas de ida y vuelta. Canarias y El Caribe en contexto colonial

    2004-12-01

    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. El azúcar, la trata de esclavos, los cultivos de plátano, grana y tabaco son los ejemplos escogidos para este análisis comparado. 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

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

    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.

    Full Text Available Muitos pesquisadores do setor turístico têm utilizado a metodologia da capacidade de carga. 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. Many researchers in the tourism sector have used the methodology of carrying capacity. The basic principie is to establish a maximum number of visitors in some place in order to minimize the impact of tourism. However, this methodology is incomplete as it only relates the impacts of tourist activity to the number of visitors, without considering some of the subjective and qualitative aspects of the effects of tourism. This research demonstrates the unscientific nature of this methodology and stresses that limiting the number of visitors to a locality is only one method to control the impacts of tourism.

  17. Globalization in the post - colonial world

    Korobeynikova Larisa A.

    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.

    The incidence rate of mammary neoplasia in a large colony of beagles and its relationship to internal skeletal and/or liver radiation, age, relatively late ovariectomy (4 years and older), endometritis, parity status, and adrenal weight was examined. Of these various factors, age was the only condition that was clearly correlated with changes in the mammary tumor incidence. The rate became significant at approximately eight years of age and increased progressively throughout the successively older age classes. Within the female dogs, the incidence of mammary cancer was higher that that of any other form of spontaneous malignancy

    Full Text Available Foucault’s concept of pastoral power is envisioned as a technique of power developed from the medieval period and carried through into modern political rationalities. As such, it is an old power technique – which originated in Christian institutions – in a new political shape, which he coined governmentality. This article uses Foucault’s genealogy of pastoral power and governmentality to discuss the intersection of domination and technology of self in the Greenlandic colonial context and to bring out the central role of religion in Foucault’s conceptualisation of governmentality.

    A good edge plot should use continuous thin lines to describe the complete contour of the captured object. However, the detection of weak edges is a challenging task because of the associated low pixel intensities. Ant Colony Optimization (ACO) has been employed by many researchers to address this problem. The algorithm is a meta-heuristic method developed by mimicking the natural behaviour of ants. It uses iterative searches to find the optimal solution that cannot be found via traditional optimization approaches. In this work, ACO is employed to track and repair broken edges obtained via conventional Sobel edge detector to produced a result with more connected edges.

  3. CHRISTIANITY AND COLONIALISM IN SOME ENGLISH SHORT STORIES

    Directory of Open Access Journals (Sweden)

    Tatang Iskarna

    2017-04-01

    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”.

  4. Inbred or Outbred? Genetic Diversity in Laboratory Rodent Colonies

    2017-01-01

    Nonmodel rodents are widely used as subjects for both basic and applied biological research, but the genetic diversity of the study individuals is rarely quantified. University-housed colonies tend to be small and subject to founder effects and genetic drift; so they may be highly inbred or show substantial genetic divergence from other colonies, even those derived from the same source. Disregard for the levels of genetic diversity in an animal colony may result in a failure to replicate results if a different colony is used to repeat an experiment, as different colonies may have fixed alternative variants. Here we use high throughput sequencing to demonstrate genetic divergence in three isolated colonies of Mongolian gerbil (Meriones unguiculatus) even though they were all established recently from the same source. We also show that genetic diversity in allegedly “outbred” colonies of nonmodel rodents (gerbils, hamsters, house mice, deer mice, and rats) varies considerably from nearly no segregating diversity to very high levels of polymorphism. We conclude that genetic divergence in isolated colonies may play an important role in the “replication crisis.” In a more positive light, divergent rodent colonies represent an opportunity to leverage genetically distinct individuals in genetic crossing experiments. In sum, awareness of the genetic diversity of an animal colony is paramount as it allows researchers to properly replicate experiments and also to capitalize on other genetically distinct individuals to explore the genetic basis of a trait.

  6. 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.

    Swartz, Sally

    2010-05-01

    In this paper I outline a brief period in the history of the British Empire, during which colonial lunatic asylum policy began to be formulated. I begin with a scandal that erupted in Jamaica and suggest that this set in motion processes that led to critical changes in asylum administration. The first of these processes was an audit of hospitals and asylums in the colonies. The results of the audit and the policy that emerged from it marked the beginning of systematic regulation of lunatic asylum practice across the British Empire. It revealed a formulation of policy that was intended to cut across the self-governing regimes that had up to this point been allowed to evolve. Drawing on the work of Michel Foucault and Nikolas Rose, I argue that the policy and the practices associated with it contribute to an understanding of the emergence of the psy-sciences in colonial settings. They illustrate the establishment of a panoptic gaze on previously neglected insane spaces. Systematic surveillance constituted government at a distance and made colonial lunacy administration a governable discursive space. The regulation of the medical officers, lunatic attendants, and hospital boards began the process of creating a professional psychiatric workforce. I conclude with a discussion of the implications and the mixed impact of this policy change for the mentally ill across the empire, over the ensuing decades.

    The Jackson Laboratory Colony Management System (JCMS) is a software application for managing data and information related to research mouse colonies, associated biospecimens, and experimental protocols. JCMS runs directly on computers that run one of the PC Windows operating systems, but can be accessed via web browser interfaces from any computer running a Windows, Macintosh, or Linux operating system. JCMS can be configured for a single user or multiple users in small- to medium-size work groups. The target audience for JCMS includes laboratory technicians, animal colony managers, and principal investigators. The application provides operational support for colony management and experimental workflows, sample and data tracking through transaction-based data entry forms, and date-driven work reports. Flexible query forms allow researchers to retrieve database records based on user-defined criteria. Recent advances in handheld computers with integrated barcode readers, middleware technologies, web browsers, and wireless networks add to the utility of JCMS by allowing real-time access to the database from any networked computer.

  15. Fish skin bacteria: Colonial and cellular hydrophobicity.

    Science.gov (United States)

    Sar, N; Rosenberg, E

    1987-05-01

    Bacteria were desorbed from the skin of healthy, fast-swimming fish by several procedures, including brief exposure to sonic oscillation and treatment with nontoxic surface active agents. The surface properties of these bacteria were studied by measuring their adhesion to hexadecane, as well as by a newly developed, simple method for studying the hydrophobicity of bacterial lawns. This method, referred to as the "Direction of Spreading" (DOS) method, consists of recording the direction to which a water drop spreads when introduced at the border between bacterial lawns and other surfaces. Of the 13 fish skin isolates examined, two strains were as hydrophobic as polystyrene by the DOS method. Suspended cells of one of these strains adhered strongly to hexadecane (84%), whereas cells of the other strain adhered poorly (13%). Another strain which was almost as hydrophobic as polystyrene by the DOS method did not adhere to hexadecane at all. Similarly, lawns of three other strains were more hydrophobic than glass by the DOS method, but cell suspensions prepared from these colonies showed little or no adhesion to hexadecane. The high colonial but relatively low cellular hydrophobicity could be due to a hydrophobic slime that is removed during the suspension and washing procedures. The possibility that specific bacteria assist in fish locomotion by changing the surface properties of the fish skin and by producing drag-reducing polymers is discussed.

  16. First recorded loss of an emperor penguin colony in the recent period of Antarctic regional warming: implications for other colonies.

    Directory of Open Access Journals (Sweden)

    Philip N Trathan

    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.

  18. Coalescing colony model: Mean-field, scaling, and geometry

    Carra, Giulia; Mallick, Kirone; Barthelemy, Marc

    2017-12-01

    We analyze the coalescing model where a `primary' colony grows and randomly emits secondary colonies that spread and eventually coalesce with it. This model describes population proliferation in theoretical ecology, tumor growth, and is also of great interest for modeling urban sprawl. Assuming the primary colony to be always circular of radius r (t ) and the emission rate proportional to r (t) θ , where θ >0 , we derive the mean-field equations governing the dynamics of the primary colony, calculate the scaling exponents versus θ , and compare our results with numerical simulations. We then critically test the validity of the circular approximation for the colony shape and show that it is sound for a constant emission rate (θ =0 ). However, when the emission rate is proportional to the perimeter, the circular approximation breaks down and the roughness of the primary colony cannot be discarded, thus modifying the scaling exponents.

    Full Text Available A erva-mate (Ilex paraguariensis A. St. Hil. é uma espécie nativa brasileira de grande interesse econômico. Programas de melhoramento genético dessa espécie têm visado ao aumento da produtividade de biomassa e qualidade. A polinização controlada permite a combinação de características desejáveis da espécie. Para isso, técnicas adequadas de polinização controlada devem ser disponibilizadas. Este trabalho teve por objetivo definir uma metodologia para a polinização controlada de erva-mate. Para isso, utilizou-se um teste clonal de 15 anos de idade na Embrapa Florestas-Colombo-PR com nove tratamentos em flores de três árvores (repetições. As flores foram polinizadas em novembro de 2010 e os frutos, coletados em março de 2011. Os frutos e sementes produzidos foram quantificados e a viabilidade dos embriões, avaliada pelo teste de tetrazólio. Os dados foram analisados com base no procedimento GLM do programa R. Maior quantidade de frutos e sementes foi observada na polinização controlada comparativamente à polinização livre. Conclui-se que a polinização controlada após a antese dessa espécie deve ser realizada em dois dias consecutivos, para assegurar boa produção de sementes em erva-mate.

    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.

  3. Improved Ant Colony Clustering Algorithm and Its Performance Study

    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. PMID:26839533

  4. Neonicotinoid pesticides can reduce honeybee colony genetic diversity.

    Directory of Open Access Journals (Sweden)

    Nadège Forfert

    Full Text Available 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.

  5. Laser-induced speckle scatter patterns in Bacillus colonies

    2014-10-01

    Full Text Available Label-free bacterial colony phenotyping technology called BARDOT (BActerial Rapid Detection using Optical scattering Technology provided successful classification of several different bacteria at the genus, species, and serovar level. Recent experiments with colonies of Bacillus species provided strikingly different characteristics of elastic light scatter (ELS patterns, which were comprised of random speckles compared to other bacteria, which are dominated by concentric rings and spokes. Since this laser-based optical sensor interrogates the whole volume of the colony, 3-D information of micro- and macro-structures are all encoded in the far-field scatter patterns. Here, we present a theoretical model explaining the underlying mechanism of the speckle formation by the colonies from Bacillus species. Except for Bacillus polymyxa, all Bacillus spp. produced random bright spots on the imaging plane, which presumably dependent on the cellular and molecular organization and content within the colony. Our scatter model-based analysis revealed that colony spread resulting in variable surface roughness can modify the wavefront of the scatter field. As the center diameter of the Bacillus spp. colony grew from 500 μm to 900 μm, average speckles area decreased 2-fold and the number of small speckles increased 7-fold. In conclusion, as Bacillus colony grows, the average speckle size in the scatter pattern decreases and the number of smaller speckle increases due to the swarming growth characteristics of bacteria within the colony.

    Hemin was found to enhance the growth of murine erythroid colonies in culture. In the presence of 100 mU/ml erythropoietin (EPO), the addition of hemin (0.05-0.2 mM) resulted in the growth of twice as many colonies as were obtained with EPO alone. Hemin also significantly increased erythroid colony formation in culture in the absence of added EPO. Hemoblobin synthesis as measured by the incorporation of 59 Fe into cyclohexanone extractable heme was augmented in culture by hemin. Neither Δ-aminolevulinic acid, a hemin precursor, nor FeCl 3 increased colony number. (author)

    Full Text Available The following article should not be dismissed as yet another attempt to construct a renewed round ofrevisionism in history. On the contrary, it aims to explore the possibility of scaling down the dominant Eurocentric epistemology that served as a basis for a stereotypical frame of knowledge about Central Asia. The majority of researchers of the region do not deem the need to review the scale of contradictory clashes created by the notion of Eurocentrism. The latter is reflected in numerous articles about the frozen (and sadly deadlock dilemma on why and how were the lands of Tajiks, Uzbeks and Kazakhs divided. By publishing conventional analyses on the region's "clumsy separation", experts illustrate their subaltern, narrowly framed by the colonial world, knowledge and hence, remain as gravestones of the Eurocentric methodology. In the process of such explication, the most important role is allocated to the modern culture, which encouraged the formation of the paradox, represented to us via the paraphrased Soviet aphorism: modernity and coloniality are twin brothers. The initiation of the process of decolonizing the mind within the five republics of the region is possible. One of the solutions involves recognizing the integrity of the pluralist-cycled culture and philosophy of the region. The proposed act will allow shrinking the focus on the knowledge within the limited national units and frames (thus, lessening the degree of'fetishism of the national identity', and rather creating conditions for designing the "bridge", linking different cultures, ideologies and institutional spaces in Central Asia, as a transnational intellectual matrix. The aforementioned theory will provide a basis and structure for empirical facts, and, therefore, drive the researchers from merely constituting to critically thinking, and consequently, inspire to come upon new approaches and fields of study, connecting them with the existing, colonial experiences.

    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.

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.

  16. Optic disc detection using ant colony optimization

    Dias, Marcy A.; Monteiro, Fernando C.

    2012-09-01

    The retinal fundus images are used in the treatment and diagnosis of several eye diseases, such as diabetic retinopathy and glaucoma. This paper proposes a new method to detect the optic disc (OD) automatically, due to the fact that the knowledge of the OD location is essential to the automatic analysis of retinal images. Ant Colony Optimization (ACO) is an optimization algorithm inspired by the foraging behaviour of some ant species that has been applied in image processing for edge detection. Recently, the ACO was used in fundus images to detect edges, and therefore, to segment the OD and other anatomical retinal structures. We present an algorithm for the detection of OD in the retina which takes advantage of the Gabor wavelet transform, entropy and ACO algorithm. Forty images of the retina from DRIVE database were used to evaluate the performance of our method.

    We present a model which aims at describing the morphology of colonies of Proteus mirabilis and Bacillus subtilis. Our model is based on a cellular automaton which is obtained by the adequate discretisation of a diffusion-like equation, describing the migration of the bacteria, to which we have added rules simulating the consolidation process. Our basic assumption, following the findings of the group of Chuo University, is that the migration and consolidation processes are controlled by the local density of the bacteria. We show that it is possible within our model to reproduce the morphological diagrams of both bacteria species. Moreover, we model some detailed experiments done by the Chuo University group, obtaining a fine agreement.

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.

  5. Dynamics of the Presence of Israeli Acute Paralysis Virus in Honey Bee Colonies with Colony Collapse Disorder

    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 This articles aims to revise the traditional theory according to which the Mercurio Peruano newspaper was closed down by the Spanish colonial authorities in order to pre-empt the development of nationalist sentiment in Peru. Available primary sources not only reveal multiple inconsistencies in this theory, but clearly prove that the closure of this renowned newspaper could not have been the result of instructions received from metropolitan Spain, given that the authorities in Madrid were informed of its closure once it had already taken place.Este artículo tiene por objetivo revisar la visión tradicional de la clausura del Mercurio Peruano, que se venía atribuyendo a una Administración colonial deseosa de evitar el surgimiento de un protonacionalismo peruano. Contrastando la historiografía existente con las fuentes primarias disponibles, se evidencian las múltiples inconsistencias de dicha visión y se demuestra fehacientemente que el cierre del Mercurio Peruano no pudo ser el resultado de una decisión de las autoridades metropolitanas, que se enteraron de su cierre a posteriori.

    Full Text Available Rabbia, dolore, incredulità si mescolano in un turbinio di emozioni quando, dalle affissioni che quasi quotidianamente si danno il cambio, si legge il necrologio di un “qualcuno” che sappiamo ucciso dal cancro. E pensiamo che, ancora e forse per tanto tempo, potremmo essere più fortunati. E non c’è pace, non c’è consolazione per quei giorni di vita vissuta, strappata, stropicciata, rubata da un mostro che non sempre è possibile sconfiggere finché non subentra la stanchezza, la rassegnazione, la secchezza delle ghiandole lacrimali. Unico strumento per cercare di “cambiare le cose”, per quanto difficile possa sembrare farlo, è combattere, perché la lotta per un ambiente più vivibile sarà una conquista per noi e per i nostri figli, un’eredità che non ha prezzo. La voglia di “gridare” la sofferenza di chi vive la realtà di uno sviluppo insostenibile si è da tempo trasformata ad Augusta in una battaglia di sensibilizzazione alla ormai annosa problematica e nel profondo desiderio di raccontare, far conoscere, testimoniare emozioni, desideri, sogni di chi vive in prima persona o ha vissuto la malattia di un proprio caro perché tutto questo possa servire a spingere verso quel mutamento culturale, storico, ambientale a cui tutti noi agogniamo.

  12. Between Past and Present: The Sociopsychological Constructs of Colonialism, Coloniality and Postcolonialism.

    Science.gov (United States)

    Tomicic, Ana; Berardi, Filomena

    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

  13. Metodologia para el analisis de demanda laboral mediante datos de Internet: el caso colombiano

    Directory of Open Access Journals (Sweden)

    Jeisson Arley Cardenas Rubio

    2015-06-01

    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.

  1. Colony strength and queen replacement in Melipona marginata (Apidae: Meliponini

    Directory of Open Access Journals (Sweden)

    A. de M. P. Kleinert

    Full Text Available Physogastric queens of Melipona marginata were removed from their colonies in order to verify the acceptance of a new queen by workers. Colony strength was evaluated according to queen oviposition rate and comb diameters. Replacement was observed seven times. Its occurrence and speed related positively to colony strength, independently of queen's age. In weak colonies, queen replacement was observed only once, following colony population increase that occurred after introduction of combs from another colony. Worker oviposition after queen removal was observed three times: in a strong colony with virgin queens and males, and in two of the weak colonies. In the first two or three days of new queen oviposition, during which most of the eggs were eaten by the queen, worker oviposition preceded almost all provisioning and oviposition processes (POPs. After this period, worker oviposition decreased until it reached around 25% of the POPs. Daily oviposition rate of young queens decreased or was even interrupted by hatching of their first brood.

    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.

    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.

    2013-01-01

    This article posits that the hill station of Darjeeling was a unique form of colonial urbanism. It shifts historiographical interest from major urban centres in colonial India (such as Bombay or Calcutta) and instead attempts a greater understanding of smaller urban centres. In the process, it also interrogates the category of hill stations, which have been understood as exotic and scenic sites rather than as towns that were integral to the colonial economy. In arguing that hill stations, particularly Darjeeling, were not merely the scenic and healthy ‘other’ of the clamorous, dirty and diseased plains of India, it refutes suggestions that the ‘despoiling’ or overcrowding of Darjeeling was incremental to the purposes of its establishment. Instead, it suggests that Darjeeling was part of the colonial mainstream; its urbanization and inclusion into the greater colonial economy was effected from the time of its establishment. Therefore, a constant tension between its exotic and its functional elements persisted throughout. PMID:24273391

In arguing that hill stations, particularly Darjeeling, were not merely the scenic and healthy 'other' of the clamorous, dirty and diseased plains of India, it refutes suggestions that the 'despoiling' or overcrowding of Darjeeling was incremental to the purposes of its establishment. Instead, it suggests that Darjeeling was part of the colonial mainstream; its urbanization and inclusion into the greater colonial economy was effected from the time of its establishment. Therefore, a constant tension between its exotic and its functional elements persisted throughout.

    Full Text Available This research paper aims at providing some elements of analysis on the complex issue of the colonization of nature. 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.

    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. 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. 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 bee losses.

    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.

  4. Mem and Cookie: The Colonial Kitchen in Malaysia and Singapore

    Cecilia Leong-Salobir

    2015-09-01

    Full Text Available This paper examines the emergence of a distinctive colonial cuisine in the British colonies of Malaysia and Singapore beginning in the late nineteenth century. This colonial cuisine evolved over time and was a combination of culinary practices derived from European and Asian foodways, much of which came from colonial India. As in India, this acculturation developed through the reliance of colonizers on their domestic servants for food preparation. While domestic servants (as cooks, or known locally as “cookie” were generally represented as dirty, dishonest and lacking in intelligence according to colonial narratives, they were responsible for the preparation of food for the family. Asian cooks in the colonial home played a much more crucial role than the negative image painted of them by British colonizers and other historians. While the mem (short for memsahib, meaning mistress held the supervisory role of the household, it was the physical contribution of the domestic servants that enabled her to fulfill this function. The large number of servants employed enabled the mem to make the colonial home move seamlessly between the private domain of the home and the official venue for the empire’s tasks. The mem as the head of the household decided on the rituals and tasks that defined the colonial space as home, and as a bastion of white imperialism. In contrast, it was the cooks’ local knowledge that procured food. Most kitchens were fashioned according to the requirements of the servants and the cooks did all the cooking, usually preparing local dishes. The argument is that, had it not been for the servants’ input, the mems would have had to work harder. As it was, the work of the servants not only saved white labour, it helped shape colonial culture, despite the Britons’ best efforts to keep themselves socially distant. Colonial cuisine would not have developed with such distinctive features without the skills and local knowledge of

    The distribution of two colony forms of Bacillus pumilus E601 and the effect of neutron irradiation on the colony form were reported. The translucent and opaque colonies were cultured several generations to observe the proportion of two form colonies. The spores of opaque colony were irradiated at 80, 800 and 2000 Gy of fast neutron from CFBR-II pulse pile, and the survivors of opaque colony were irradiated again at the same doses. The results showed that: (1) Bacillus pumilus E601 observed two types of colony form: translucent and opaque colony; (2) the translucent colony could produce both translucent and opaque colonies in equal, while the opaque colony couldn't produce translucent colony generally; (3) neutron irradiation could affect the colony form distribution. The ratio of survival translucent colony was increased with the increase of the first neutron irradiation doses, and the second neutron irradiation also increased the ratio of translucent colony. It was concluded that the instability of translucent colony was the main reason to produce two colony forms of Bacillus pumilus E601. The strain of translucent colony had a stronger ability to resist neutron irradiation than the opaque colony. (authors)

  12. Loading pattern optimization using ant colony algorithm

    Electricite de France (EDF) operates 58 nuclear power plants (NPP), of the Pressurized Water Reactor type. The loading pattern optimization of these NPP is currently done by EDF expert engineers. Within this framework, EDF R and D has developed automatic optimization tools that assist the experts. LOOP is an industrial tool, developed by EDF R and D and based on a simulated annealing algorithm. In order to improve the results of such automatic tools, new optimization methods have to be tested. Ant Colony Optimization (ACO) algorithms are recent methods that have given very good results on combinatorial optimization problems. In order to evaluate the performance of such methods on loading pattern optimization, direct comparisons between LOOP and a mock-up based on the Max-Min Ant System algorithm (a particular variant of ACO algorithms) were made on realistic test-cases. It is shown that the results obtained by the ACO mock-up are very similar to those of LOOP. Future research will consist in improving these encouraging results by using parallelization and by hybridizing the ACO algorithm with local search procedures. (author)

    Evolutionary experiments with microbes are a powerful tool to study mutations and natural selection. These experiments, however, are often limited to the well-mixed environments of a test tube or a chemostat. Since spatial organization can significantly affect evolutionary dynamics, the need is growing for evolutionary experiments in spatially structured environments. The surface of a Petri dish provides such an environment, but a more detailed understanding of microbial growth on Petri dishes is necessary to interpret such experiments. We formulate a simple deterministic reaction–diffusion model, which successfully predicts the spatial patterns created by two competing species during colony expansion. We also derive the shape of these patterns analytically without relying on microscopic details of the model. In particular, we find that the relative fitness of two microbial strains can be estimated from the logarithmic spirals created by selective sweeps. The theory is tested with strains of the budding yeast Saccharomyces cerevisiae for spatial competitions with different initial conditions and for a range of relative fitnesses. The reaction–diffusion model also connects the microscopic parameters like growth rates and diffusion constants with macroscopic spatial patterns and predicts the relationship between fitness in liquid cultures and on Petri dishes, which we confirmed experimentally. Spatial sector patterns therefore provide an alternative fitness assay to the commonly used liquid culture fitness assays. (paper)

  14. Image steganalysis using Artificial Bee Colony algorithm

    Steganography is the science of secure communication where the presence of the communication cannot be detected while steganalysis is the art of discovering the existence of the secret communication. Processing a huge amount of information takes extensive execution time and computational sources most of the time. As a result, it is needed to employ a phase of preprocessing, which can moderate the execution time and computational sources. In this paper, we propose a new feature-based blind steganalysis method for detecting stego images from the cover (clean) images with JPEG format. In this regard, we present a feature selection technique based on an improved Artificial Bee Colony (ABC). ABC algorithm is inspired by honeybees' social behaviour in their search for perfect food sources. In the proposed method, classifier performance and the dimension of the selected feature vector depend on using wrapper-based methods. The experiments are performed using two large data-sets of JPEG images. Experimental results demonstrate the effectiveness of the proposed steganalysis technique compared to the other existing techniques.

    Healthcare professionals usually should make complex decisions with far reaching consequences and associated risks in health care fields. As it was demonstrated in other industries, the ability to drill down into pertinent data to explore knowledge behind the data can greatly facilitate superior, informed decisions to ensue the facts. Nature has always inspired researchers to develop models of solving the problems. Bee colony algorithm (BCA), based on the self-organized behavior of social insects is one of the most popular member of the family of population oriented, nature inspired meta-heuristic swarm intelligence method which has been proved its superiority over some other nature inspired algorithms. The objective of this model was to identify valid novel, potentially useful, and understandable correlations and patterns in existing data. This review employs a thematic analysis of online series of academic papers to outline BCA in medical hive, reducing the response and computational time and optimizing the problems. To illustrate the benefits of this model, the cases of disease diagnose system are presented.

    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.

    2007-06-01

    Clonogenic assay is a widely used experimental approach to test for the effects of drugs/genes on the growth and proliferative characteristics of cells in vitro. Accurate quantitation of treatment effects in clonogeneic assays depends on the ability to visualize and count cell colonies precisely. We report a novel method (referred as ETeB) for staining cell colonies grown on plastic and specially coated substrates like collagen. Using colon cancer cell lines grown on plastic and collagen, we compared the colony staining efficiencies of the widely used methylene blue, and Ethidium bromide (ETeB) stains. Results show that the ETeB protocol works well on plastic and is extremely effective for staining colonies on collagen when compared to methylene blue. The key features and advantages of ETeB technique are; (a) reduction in background for colonies grown on collagen and possibly other substrates, (b) the whole procedure takes less than a minute, (c) no post-stain washing step is required which eliminates colony losses for cell lines that are loosely adherent, (d) colony visualization and counting can be done immediately following the staining procedure using a standard UV illuminator and software, and (e) the method works across a wide variety of cell lines. The simplicity and robustness of this procedure should warrant its usage in both small and large-scale clonogenic experiments.

  20. The colonial context of Filipino American immigrants' psychological experiences.

    2013-07-01

    Because of the long colonial history of Filipinos and the highly Americanized climate of postcolonial Philippines, many scholars from various disciplines have speculated that colonialism and its legacies may play major roles in Filipino emigration to the United States. However, there are no known empirical studies in psychology that specifically investigate whether colonialism and its effects have influenced the psychological experiences of Filipino American immigrants prior to their arrival in the United States. Further, there is no existing empirical study that specifically investigates the extent to which colonialism and its legacies continue to influence Filipino American immigrants' mental health. Thus, using interviews (N = 6) and surveys (N = 219) with Filipino American immigrants, two studies found that colonialism and its consequences are important factors to consider when conceptualizing the psychological experiences of Filipino American immigrants. Specifically, the findings suggest that (a) Filipino American immigrants experienced ethnic and cultural denigration in the Philippines prior to their U.S. arrival, (b) ethnic and cultural denigration in the Philippines and in the United States may lead to the development of colonial mentality (CM), and (c) that CM may have negative mental health consequences among Filipino American immigrants. The two studies' findings suggest that the Filipino American immigration experience cannot be completely captured by the voluntary immigrant narrative, as they provide empirical support to the notion that the Filipino American immigration experience needs to be understood in the context of colonialism and its most insidious psychological legacy- CM.

    Full Text Available This article focuses on the women’s magazine Ellas, published in the mid-nineteenth century in Madrid, and discusses its relationship with other approximately contemporary magazines and newspapers in order to contribute to a reconstruction of the history of women’s publications in the Spanish press. The approach is based on an analysis of the text of each issue of the magazine and comparison with other publications, where applicable. Key features of the article include a reflection on the social rights of women, an attempt to analyse the main differences between women and men and defining features of sexual gender, the need for women’s education, etc. Studying the magazine’s content clearly reveals a continual tension between progressive and conservative ideas typical of the historical context in which gender studies emerged in Spain.Este artículo centra su atención en la revista para mujeres Ellas, publicada a mediados del siglo XIX en Madrid. Analiza, asimismo, la relación de esta publicación con algunas otras revistas y periódicos de su contexto histórico próximo, con el fin de contribuir a la reconstrucción de una Historia de las publicaciones para mujeres en la prensa española. Para ello se utiliza el análisis de textos que forman parte de los números que componen la revista, así como el análisis comparativo entre publicaciones, cuando es pertinente. Entre los aspectos de mayor interés que el artículo pone de relieve se encuentra la reflexión sobre los derechos sociales de las mujeres, el intento de análisis de las principales diferencias entre mujeres y hombres y de los rasgos definitorios de los géneros sexuales, la necesidad de educación de las mujeres, entre otros. El estudio del contenido de la publicación revela claramente una tensión contradictoria continua entre las ideas progresistas y las ideas conservadoras propias del momento histórico que dieron origen en España al nacimiento de los estudios de género.

    Lo "gnomone" di cui si parla in questo libro non è quello stilo, più o meno monumentale, la cui ombra indica l'ora solare, ma un semplice strumento matematico: una figura geometrica, piana o solida, che aggiunta a un'altra ne genera una simile. Si tratta quindi di una tecnica, ampiamente diffusa nell'antichità, atta a ingrandire o rimpicciolire una forma conservandone l'aspetto. Lo gnomone non aveva solo importanza geometrica. Dalla semplice operazione di correzione "gnomonica" di una figura sono dipesi infatti la stessa nozione di numero, la definizione di vari concetti dell'Analisi e alcuni tra i principali algoritmi numerici e algebrici della matematica.

    Thomas Hughes has shown the links which existed between politics and technological and economic changes. From this point of view, the relationship between colonialism and the development of nuclear systems is interesting. There is a significant continuity from the colonial Empires to the uranium supply networks. Americans and the British worked together to prospect and to exploit uranium deposits, in particular in South Africa. On their side, the French had similar activities in Madagascar, Gabon and Niger. In both cases, important post-colonial ties have been maintained based on techno-politics

    Full Text Available The article looks back at the films commissioned and produced by the Dutch governments about their colony in teh East-Indies between 1912 and 1962. The main focus is on the newsreels and documentaries about the colonial war between the Netherlands and Indonesia  from 1945 to 1949. The article reviews these films and the re-use of their footage in later television programs. The programs often look back at the colonial war in ways that go beyond the purpose of the original films and the article aims to show the methods that are used to do this.

    This research aims to describe portfolio optimization using clustering methods with ant colony approach. Two stock portfolios of LQ45 Indonesia is proposed based on the cluster results obtained from ant colony optimization (ACO). The first portfolio consists of assets with ant colony displacement opportunities beyond the defined probability limits of the researcher, where the weight of each asset is determined by mean-variance method. The second portfolio consists of two assets with the assumption that each asset is a cluster formed from ACO. The first portfolio has a better performance compared to the second portfolio seen from the Sharpe index.

    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.

    2017-06-01

    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.

    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.

    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.

  17. Honey Bee Colonies Remote Monitoring System

    2016-12-01

    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.

  18. Transits of Venus and Colonial India

    2012-09-01

    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.

    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 five 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. Sixty 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, 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.

  1. Revisiting the effect of colonial institutions on comparative economic development.

    Directory of Open Access Journals (Sweden)

    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.

  7. Energy Colonialism Powers the Ongoing Unnatural Disaster in Puerto Rico

    Directory of Open Access Journals (Sweden)

    Catalina M. de Onís

    2018-01-01

    Full Text Available On September 20, 2017, Hurricane María made landfall in Puerto Rico. Blasting the Caribbean archipelago with 155-mile/h winds, this, in many ways, unnatural disaster exposed the brutal consequences of energy colonialism and an extractivist economy, as well as ongoing and increasing advocacy for decentralized solar infrastructure by many local residents and other renewables supporters. This paper argues that acknowledging colonial power relations and their consequences is essential for studying the interplay of energy systems, environments, and actors. To support this claim, this essay outlines Puerto Rico’s history as a US colony by focusing on key policies and their implications; examines openings for and barriers to decentralized, community solar in Puerto Rico; and concludes by discussing future research directions on just energy transitions and the imperative of uprooting colonialism and agitating for community self-determination and energy justice in these transformations.

    2011-05-01

    Full Text Available A proposed broader or Indigenized social determinants of health framework includes "colonialism" along with other global processes. What does it mean to understand Canadian colonialism as a distal determinant of Indigenous health? This paper reviews pertinent discourses surrounding Indigenous mental health in Canada.With an emphasis on the notion of intergenerational trauma, there are real health effects of social, political, and economic marginalization embodied within individuals, which can collectively affect entire communities. Colonialism can also be enacted and reinforced within Indigenous mental health discourse, thus influencing scholarly and popular perceptions. Addressing this distal determinant through policy work necessitates that improving Indigenous health is inherently related to improving these relationships, i.e. eliminating colonial relations, and increasing self-determination.

    Because video data are complex and are comprised of many images, mining information from video material is difficult to do without the aid of computer software. Video bioinformatics is a powerful quantitative approach for extracting spatio-temporal data from video images using computer software to perform dating mining and analysis. In this article, we introduce a video bioinformatics method for quantifying the growth of human embryonic stem cells (hESC) by analyzing time-lapse videos collected in a Nikon BioStation CT incubator equipped with a camera for video imaging. In our experiments, hESC colonies that were attached to Matrigel were filmed for 48 hours in the BioStation CT. To determine the rate of growth of these colonies, recipes were developed using CL-Quant software which enables users to extract various types of data from video images. To accurately evaluate colony growth, three recipes were created. The first segmented the image into the colony and background, the second enhanced the image to define colonies throughout the video sequence accurately, and the third measured the number of pixels in the colony over time. The three recipes were run in sequence on video data collected in a BioStation CT to analyze the rate of growth of individual hESC colonies over 48 hours. To verify the truthfulness of the CL-Quant recipes, the same data were analyzed manually using Adobe Photoshop software. When the data obtained using the CL-Quant recipes and Photoshop were compared, results were virtually identical, indicating the CL-Quant recipes were truthful. The method described here could be applied to any video data to measure growth rates of hESC or other cells that grow in colonies. In addition, other video bioinformatics recipes can be developed in the future for other cell processes such as migration, apoptosis, and cell adhesion. PMID:20495527

El peor ejemplo lo refl eja la situación en la cual el 80% de las plantas de tratamiento de agua para consumo que existen en las 47 localidades urbanas del Departamento del Tolima (Colombia en las cuales se aplicó la metodología, una vez construidas nunca entraron en operación, además, la mayoría de las inversiones en acueductos se centran en ampliar la capacidad de captación de agua, cuando en la mayoría de los casos no se requiere.

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

    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.

    During breeding, king penguins do not build nests, however they show strong territorial behaviour and keep a pecking distance to neighbouring penguins. Penguin positions in breeding colonies are highly stable over weeks and appear regularly spaced, but thus far no quantitative analysis of the structural order inside a colony has been performed. In this study, we use the radial distribution function to analyse the spatial coordinates of penguin positions. Coordinates are obtained from aerial images of two colonies that were observed for several years. Our data demonstrate that the structural order in king penguin colonies resembles a 2D liquid of particles with a Lennard-Jones-type interaction potential. We verify this using a molecular dynamics simulation with thermally driven particles, whereby temperature corresponds to penguin movements, the energy well depth ɛ of the attractive potential corresponds to the strength of the colony-forming behaviour, and the repulsive zone corresponds to the pecking radius. We can recapitulate the liquid disorder of the colony, as measured by the radial distribution function, when the particles have a temperature of several (1.4–10) \

  3. No intracolonial nepotism during colony fissioning in honey bees

    Most species of social insects have singly mated queens, but in some species each queen mates with numerous males to create a colony whose workers belong to multiple patrilines. This colony genetic structure creates a potential for intracolonial nepotism. One context with great potential for such nepotism arises in species, like honey bees, whose colonies reproduce by fissioning. During fissioning, workers might nepotistically choose between serving a young (sister) queen or the old (mother) queen, preferring the former if she is a full-sister but the latter if the young queen is only a half-sister. We examined three honeybee colonies that swarmed, and performed paternity analyses on the young (immature) queens and samples of workers who either stayed with the young queens in the nest or left with the mother queen in the swarm. For each colony, we checked whether patrilines represented by immature queens had higher proportions of staying workers than patrilines not represented by immature queens. We found no evidence of this. The absence of intracolonial nepotism during colony fissioning could be because the workers cannot discriminate between full-sister and half-sister queens when they are immature, or because the costs of behaving nepotistically outweigh the benefits.

    1976-01-01

    Suspensions of human bone marrow cells were subjected to 137 Cs irradiation in vitro and then cultured in semisolid agar medium. Cultures of irradiated cells were stimulated with colony-stimulating activity (CSA) of different potencies, and it was found that the amount of stimulation applied to cultures influenced the apparent kill of colony-forming cells (CFC). It was also found that the effects of irradiation on colony formation were not confined to CFC kill since medium conditioned by cells during irradiation exhibited stimulatory and inhibitory properties after treatment by 600 and 1000 rads, respectively. Studies in which irradiated cells were pretreated with hydroxyurea indicated that CFC in the DNA synthetic phase of the cell cycle were particularly sensitive to low doses of irradiation. The proliferative capacity of CFC surviving 1000 rads was undiminished as judged by their ability to form large colonies. Estimates of CFC kill by hydroxyurea were also affected by the level of CSA

    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.

    Full Text Available Filamentous diazotrophic Cyanobacteria of the genus Trichodesmium, often found in colonial form, provide an important source of new nitrogen to tropical and subtropical marine ecosystems. Colonies are composed of several clades of Trichodesmium in association with a diverse community of bacterial and eukaryotic epibionts. We used high-throughput 16S rRNA and nifH gene sequencing, carbon (C and dinitrogen (N2 fixation assays, and metagenomics to describe the diversity and functional potential of the microbiome associated with Trichodesmium colonies collected from the North Pacific Subtropical Gyre (NPSG. The 16S rRNA and nifH gene sequences from hand-picked colonies were predominantly (>99% from Trichodesmium Clade I (i.e., T. thiebautii, which is phylogenetically and ecologically distinct from the Clade III IMS101 isolate used in most laboratory studies. The bacterial epibiont communities were dominated by Bacteroidetes, Alphaproteobacteria, and Gammaproteobacteria, including several taxa with a known preference for surface attachment, and were relatively depleted in the unicellular Cyanobacteria and small photoheterotrophic bacteria that dominate NPSG surface waters. Sequencing the nifH gene (encoding a subcomponent of the nitrogenase enzyme identified non-Trichodesmium diazotrophs that clustered predominantly among the Cluster III nifH sequence-types that includes putative anaerobic diazotrophs. Trichodesmium colonies may represent an important habitat for these Cluster III diazotrophs, which were relatively rare in the surrounding seawater. Sequence analyses of nifH gene transcripts revealed several cyanobacterial groups, including heterocystous Richelia, associated with the colonies. Both the 16S rRNA and nifH datasets indicated strong differences between Trichodesmium epibionts and picoplankton in the surrounding seawater, and also between the epibionts inhabiting Trichodesmium puff and tuft colony morphologies.

    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.

The goal is to recover some of his most important contributions to the understanding of colonial racism from his theory of alienation. Fanon presents alienation as a prior step to slavery and colonialism, necessary for the maintenance of economic exploitation and analyzes the identity conducts of self shame as a result of colonial domination.

    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.

    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.

    Coloniality in nesting birds represents an important life history strategy for maximizing reproductive success. Birds nesting near the edge of colonies tend to have lower reproductive success than individuals nesting near colony centers, and offspring of edge-nesting parents may be impaired relative to those of central-nesting parents. We used fecal corticosterone metabolites in California gull chicks (Larus californicus) to examine whether colony size or location within the colony influenced a chick's physiological condition. We found that chicks being raised near colony edges had higher fecal corticosterone metabolite concentrations than chicks raised near colony centers, but that colony size (ranging from 150 to 11,554 nests) had no influence on fecal corticosterone levels. Fecal corticosterone metabolite concentrations also increased with chick age. Our results suggest that similarly aged California gull chicks raised near colony edges may be more physiologically stressed, as indicated by corticosterone metabolites, than chicks raised near colony centers.

    Full Text Available Uno de los fundamentos de la economía colonial de la Nueva Granada fue la extracción de metales preciosos, particularmente de los placeres auríferos; lo cual, conjuntamente con la utilización de la mano de obra esclava, hicieron que la experiencia de la Colombia colonial fuera completamente distinta a los otros espacios controlados por la metrópoli española. Pero, además, se trata de una experiencia completamente marginal, pues no fue en nada comparable con el volumen y el valor de la producción de plata de la Nueva Castilla y de la Nueva España, como tampoco de la producción aurífera del Brasil colonial.

    Colonial buildings, including houses, have been considered as a representation of climate-responsive architecture. The design was thought to be a hybrid model of Dutch and tropical architecture. It was created by way of reinventing tropical and Dutch architecture design principles, and expressed in a new form, i.e. neither resembling Dutch nor tropical building. Aside from this new image, colonial house does show good climatic responses. Previous researches on colonial house generally focus on qualitative assessment of climate performance of the building. Yet this kind of study tends to concentrate on building elements, e.g. wall, window, etc. The present study is designed to give more complete picture of architecture design strategy of the house by exploring and analysing thermal performance of colonial buildings and their related architecture design strategies. Field measurements are conducted during the dry season in several colonial building in Surabaya. Air temperature and humidity are both taken, representing internal and external thermal conditions of the building. These data are then evaluated to determine thermal performance of the house. Finally, various design strategies are examined in order to reveal their significant contributions to its thermal performance. Results of the study in Surabaya confirm findings of the previous researches that are conducted in other locations, which stated that thermal performance of the house is generally good. Passive design strategies such as mass effect and ventilation play an important role in determining performance of the building.

    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.

    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.

    1985-08-01

    The Colonie site is a DOE Formerly Utilized Sites Remedial Action Program (FUSRAP) site located in the Town of Colonie, New York, and consisting of an interim storage site and several vicinity properties. The Colonie Interim Storage Site (CISS) is the former National Lead (NL) Industries plant located at 1130 Central Avenue. There are 11 vicinity properties that received remedial action in 1984: 7 located south of the site on Yardboro and Palmer Avenues just across the Colonie-Albany town limits in Albany, and 4 located northwest of the site along Central Avenue in Colonie. Of these properties, nine are residences and two are commercial properties. This document describes the engineering design, construction, and associated plans for remedial action on the vicinity properties and the interim storage site. These plans include both radiological and chemical work. Radiological work includes: excavating the above-guideline radioactive wastes on the vicinity properties; designing required facilities for the interim storage site; preparing the interim storage site to receive these contaminated materials; transporting the contaminated materials to the interim waste storage stockpile; and preparing necessary schedules for accomplishing the remedial actions. Chemical work involves: developing the Resource Conservation and Recovery Act (RCRA) closure plans; neutralizing chemical hazards associated with plating solutions; inventorying on-site chemicals; and disposal of chemicals and/or residues. 17 refs., 5 figs., 1 tab

    Alessandro Pandolfi

    2013-07-01

    Full Text Available The article critically analyses the late eighteenth century process of crisis and transformation of the concept of empire. By considering Raynal’s Histoire des deux Indes and the Enlightenment’s critique of the different imperial models, Pandolfi reconstructs the transit from classic colonialism – built around the relations between settlers, savages and slaves – to another phase characterized by the indirect exploitation of the labour force. The text underlines the ambivalence of Enlightenment towards the question of the empire by demonstrating how Raynal’s work reflects the constitutive tension of the second half of the 1700s. Therefore, through Diderot’s analysis, the author demonstrates how the moral advancement of humanity is the product of a constant interaction between the colonial rhetoric of commerce and those revolutions, which, – in different moments and places – have crossed the colonial space.

    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.

    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.

    This study presents an in-depth analysis of Alexander von Humboldt's descriptions and critical comments on the colonial society of the different regions he visited during his well-known expedition through the Americas (1799-1804). The criticisms of colonialism that he expressed, reflecting his personal convictions, have already been the focal point of many studies, but Humboldt also was able to offer a more differentiated assessment through comparisons of regional and local traditions and developments. This essay focuses on his personal diaries, which offer many interesting comments on colonial societies. These considerations and impressions made during the expedition are of particular scholarly value since they were not subject to censorship of any kind.

    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.

    Growing evidence for declines in bee populations has caused great concern because of the valuable ecosystem services they provide. Neonicotinoid insecticides have been implicated in these declines because they occur at trace levels in the nectar and pollen of crop plants. We exposed colonies of the bumble bee Bombus terrestris in the laboratory to field-realistic levels of the neonicotinoid imidacloprid, then allowed them to develop naturally under field conditions. Treated colonies had a significantly reduced growth rate and suffered an 85% reduction in production of new queens compared with control colonies. Given the scale of use of neonicotinoids, we suggest that they may be having a considerable negative impact on wild bumble bee populations across the developed world.

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

    Directory of Open Access Journals (Sweden)

    Balaji Prabhakar

    Full Text Available 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.

Mosso dall’interesse che il fenomeno della integrazione concettuale (blending suscita, il mio intervento propone una lettura del film La vita è bella di Roberto Benigni proprio in funzione del suo organizzarsi intorno a un blending che ne sostiene l’intero impianto ideativo. Il film è stato molto criticato, oltre che per un certo impaccio tecnico nella messa in scena, per il fatto di condurre un racconto di morte e sterminio attraverso un punto di vista comico. Attraverso l’applicazione del blending, insieme ad altri strumenti di analisi classica, cercherò di dimostrare come la strutturazione del racconto intorno alla duplice contaminazione di realtà e fantasia, comico e tragico, lo sottrae dal rischio di scivolare nel melodramma e nel patetismo, mantenendo alta l’empatia dello spettatore. La mia lettura sottolinea dunque come tutto il film sia costruito su un continuo blending, e ne evidenzia le modalità di realizzazione, dimostrando, attraverso un’opera ampiamente nota e di vasto consenso, come le scienze cognitive possano offrire validi strumenti di analisi che precisano pregresse intuizioni critiche e illuminano zone dell’opera d’arte rimaste in ombra o confinate alla valutazione estetica.

  7. 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

    Nuclear Power Plant is a highly complex structural system with high safety requirements. Fault location appears to be particularly important to enhance its safety. Ant Colony Optimization is a new type of optimization algorithm, which is used in the fault location and classification of nuclear power plants in this paper. Taking the main coolant system of the first loop as the study object, using VB6.0 programming technology, the NPP fault location system is designed, and is tested against the related data in the literature. Test results show that the ant colony optimization can be used in the accurate classification fault location in the nuclear power plants. (authors)

    In this work we have studied the dynamic speckle patterns of mucor fungi colonies, which were inoculated on different samples. We were interested in analyzing the development of fungi colonies in bones, since during the last two years, a series of infections by mucor fungi have been reported on patients from different hospitals in Argentina. Coincidentally, all of these infections appeared on patients that were subjected to a surgical intervention for implantation of a titanium prosthesis. Apparently, the reason of the infection was a deficient sterilization process in conjunction with an accidental contamination. We observed that fungi growth, activity and death can be distinguished by means of the dynamic speckle technique.

    López, Juan M.; Jensen, Henrik J.

    2002-02-01

    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.

    Marjan Kuchaki Rafsanjani

    2015-11-01

    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.

  12. Traditional vocations and modern professions among Tamil Brahmans in colonial and post-colonial south India.

    Fuller, C J; Narasimhan, Haripriya

    2010-01-01

    Since the nineteenth century, Tamil Brahmans have been very well represented in the educated professions, especially law and administration, medicine, engineering and nowadays, information technology. This is partly a continuation of the Brahmans' role as literate service people, owing to their traditions of education, learning and literacy, but the range of professions shows that any direct continuity is more apparent than real. Genealogical data are particularly used as evidence about changing patterns of employment, education and migration. Caste traditionalism was not a determining constraint, for Tamil Brahmans were predominant in medicine and engineering as well as law and administration in the colonial period, even though medicine is ritually polluting and engineering resembles low-status artisans' work. Crucially though, as modern, English-language, credential-based professions that are wellpaid and prestigious, law, medicine and engineering were and are all deemed eminently suitable for Tamil Brahmans, who typically regard their professional success as a sign of their caste superiority in the modern world. In reality, though, it is mainly a product of how their old social and cultural capital and their economic capital in land were transformed as they seized new educational and employment opportunities by flexibly deploying their traditional, inherited skills and advantages.

    1993-05-01

    This report describes the environmental surveillance program at the Colonie Interim Storage Site (CISS) and provides the results for 1992. The site is located in eastern New York State, approximately 6.4 km (4.0 mi) northwest of downtown Albany. From 1958 to 1984, National Lead (NL) Industries used the facility to manufacture various components from depleted and enriched uranium natural thorium. Environmental monitoring of CISS began in 1984 when Congress added, the site to the US Department of Energy's (DOE) Formerly Utilized Sites Remedial Action Program (FUSRAP). FUSRAP is a program established to identify and decontaminate or otherwise control sites where residual radioactive materials remain from the early years of the nation's atomic energy program or from commercial operations causing conditions that Congress has authorized DOE to remedy. The environmental surveillance program at CISS includes sampling networks for external gamma radiation exposure and for thorium-232 and total uranium concentrations in surface water, sediment, and groundwater. Several chemical parameters are also measured in groundwater, including total metals, volatile organics, and water quality parameters. This surveillance program assists in fulfilling the DOE policy of measuring and monitoring effluents from DOE activities and calculating hypothetical doses. Results are compared with applicable Environmental Protection Agency (EPA) and New York State Department of Environmental Conservation (NYSDEC) standards, DOE derived concentration guides (DCGs), dose limits, and other DOE requirements

Finalmente, relaciona-se esse aprofundamento à multiplicidade de propostas pedagógicas e de comunicação social que tem sido construídas pelas redes agroecológicas, o que amplia consideravelmente sobre a transformação da sociedade em sua relação com a natureza, por meio da Agroecologia como um conjunto de diretrizes para Desenvolvimento Rural Sustentável e da construção de uma Pedagogia do Alimento.

    Full Text Available A graduação em Farmácia requer o desenvolvimento de competências, habilidades e atitudes específicas a esta área. A escolha da metodologia adequada é fundamental para preparar os discentes às demandas dos serviços em saúde. Assim, o objetivo deste foi relatar a experiência da aplicação do arco de Maguerez junto aos discentes do curso de Farmácia. A prática realizou-se em maio de 2013, com sete alunos do curso de Farmácia de uma instituição privada em Quixadá, como atividade do módulo de Metodologias Ativas de Ensino Aprendizagem do Curso de Mestrado Profissional Ensino na Saúde da UECE. Consistiu na aplicação do Arco de Maguerez, seguindo as etapas de observação da realidade, elaboração dos pontos–chave, teorização, hipóteses de solução  e aplicação na realidade. O problema formulado pelos discentes foi: “ansiedade em relação às dificuldades profissionais que se pode enfrentar enquanto farmacêuticos recém-formados.” Para explicar o problema destacam-se os seguintes pontos chaves: falta de preparo para a prática profissional, ênfase em conteúdos em detrimento de uma aproximação com a realidade e novas responsabilidades exigidas pelo mercado. A teorização foi realizada através do relato de experiências das facilitadoras e a utilização de artigos científicos. Em seguida foram apontadas hipóteses de solução para o problema: reestruturação curricular e mudanças de posturas de docentes e discentes. O método finalizou com a aplicação na realidade que se deu através da elaboração de um plano de atividades a serem desenvolvidas no curso e os estudantes apresentaram entusiasmo e interesse na construção do arco.

  17. Workers' Extra-Nest Behavioral Changes During Colony Fission in Dinoponera quadriceps (Santschi).

    Medeiros, J; Araújo, A

    2014-04-01

    Ant colonies can reproduce by two strategies: independent foundation, wherein the queen starts a new colony alone, and dependent foundation, in which workers assist the queen. In the queenless species Dinoponera quadriceps (Santschi), the colony reproduces obligatorily by fission, a type of dependent foundation, but this process is not well understood. This study describes a colony fission event of D. quadriceps in the field and analyzes the influence of the fission process on workers' extra-nest behavior. Based on observations of workers outside the nest, five distinct stages were identified: monodomic stage, polydomic stage, split stage, conflict stage, and post-conflict stage. The colony was initially monodomic and then occupied a second nest before it split into two independent colonies, indicating a gradual and opportunistic dependent foundation. After the fission event, the daughter colony had aggressive conflicts with the parental colony, resulting in the latter's disappearance. Colony fission affected workers' extra-nest behavior by increasing the frequency of rubbing the gaster against the substrate (which probably has a chemical marking function) and by decreasing the frequency of foraging during the split stage. After the fission event, the number of foragers was halved and foragers remained nearer to the nest during extra-nest activity. The spatial closeness of the parental and daughter colonies led to competition that caused the extinction or migration of the parental colony. Intraspecific competition was indicated by foraging directionality at the colony level, whereby areas of neighbor colonies were avoided; this directionality was stronger while both colonies coexisted.

  18. Is there a Space for Post-Colonial Theory in the Socio-Psychological Research on Consequences of Colonial Past?

    Leone, Giovanna

    2018-04-26

    The focus of my commentary is two-fold. First, I discuss what appeared to me as the central theoretical focus of the article; the possibility to create a space, if at all, for integrating post-colonial theory into the broader research field of social and psychological studies of the consequences of colonial past. Second, I intend to show why, in my opinion, the methodological choices of the authors and the criteria adopted for corpus construction allowed for data that, although too thin to establishing the state of knowledge in the field of study on consequences of colonial past, is nevertheless very informative and thoughts-provoking. My conclusions suggest that this study is an innovative attempt at describing and grasping the results of a search guided by two among the more consolidated electronic datasets currently available for English-speaking scholars. However, this study may not easily understand which can be the space to integrate post-colonial theory in the field of research on consequences of colonial past. To better reach this aim, it is perhaps necessary to build another kind of corpus, open to other languages (starting from French) and focused also on other scientific products, as books or proceedings of congress. In addition, disciplinary boundaries have to be even more explored, starting from interdisciplinary studies on education and historical culture. In spite of these limitations, I am convinced that this innovative study by Tomicic and Berardi tackles issues of relevance to any serious effort towards reflecting on long-term consequences of colonial violence and opens up to valuable new research questions and methods, to be taken into serious account and further explored in future works.

    Full Text Available Dado que en la actualidad hay mayores posibilidades para practicar una lengua extranjera en su contexto natural con nativohablantes, es imprescindible poseer una cierta competencia intercultural a fin de que este diálogo pueda llevarse a cabo exitosamente. Sin embargo, los libros de texto convencionales editados en el país de origen de la lengua estudiada difícilmente pueden cubrir este requisito, puesto que las particularidades culturales de una sociedad sólo se vuelven interculturales al compararlas con la cultura de los alumnos. En el artículo presente se proponen varios ejercicios enfocados al aprendizaje intercultural en donde no sólo se aprenden las normas, reglas y actitudes de la cultura meta, en este caso de Alemania, Austria y Suiza, sino que también se estimula la reflexión sobre las de la cultura propia. Esta sensibilización cultural es indispensable para lograr una comunicación equitativa entre personas de diferentes culturas.

  16. PARAMETER ESTIMATION OF VALVE STICTION USING ANT COLONY OPTIMIZATION

    Directory of Open Access Journals (Sweden)

    S. Kalaivani

    2012-07-01

    Full Text Available In this paper, a procedure for quantifying valve stiction in control loops based on ant colony optimization has been proposed. Pneumatic control valves are widely used in the process industry. The control valve contains non-linearities such as stiction, backlash, and deadband that in turn cause oscillations in the process output. Stiction is one of the long-standing problems and it is the most severe problem in the control valves. Thus the measurement data from an oscillating control loop can be used as a possible diagnostic signal to provide an estimate of the stiction magnitude. Quantification of control valve stiction is still a challenging issue. Prior to doing stiction detection and quantification, it is necessary to choose a suitable model structure to describe control-valve stiction. To understand the stiction phenomenon, the Stenman model is used. Ant Colony Optimization (ACO, an intelligent swarm algorithm, proves effective in various fields. The ACO algorithm is inspired from the natural trail following behaviour of ants. The parameters of the Stenman model are estimated using ant colony optimization, from the input-output data by minimizing the error between the actual stiction model output and the simulated stiction model output. Using ant colony optimization, Stenman model with known nonlinear structure and unknown parameters can be estimated.

  19. Honeybee Colony Vibrational Measurements to Highlight the Brood Cycle.

    Directory of Open Access Journals (Sweden)

    Martin Bencsik

    Full Text Available Insect pollination is of great importance to crop production worldwide and honey bees are amongst its chief facilitators. Because of the decline of managed colonies, the use of sensor technology is growing in popularity and it is of interest to develop new methods which can more accurately and less invasively assess honey bee colony status. Our approach is to use accelerometers to measure vibrations in order to provide information on colony activity and development. The accelerometers provide amplitude and frequency information which is recorded every three minutes and analysed for night time only. Vibrational data were validated by comparison to visual inspection data, particularly the brood development. We show a strong correlation between vibrational amplitude data and the brood cycle in the vicinity of the sensor. We have further explored the minimum data that is required, when frequency information is also included, to accurately predict the current point in the brood cycle. Such a technique should enable beekeepers to reduce the frequency with which visual inspections are required, reducing the stress this places on the colony and saving the beekeeper time.

    Directory of Open Access Journals (Sweden)

    Munyaradzi Hwami

    2014-05-01

    Full Text Available This article utilizes internal colonial analyses to explore and understand the difficult educational conditions students from peasantry background experience in Zimbabwe’s universities. The article proposes that the subordinate position and related educational experiences of peasantry students since the year 2000 are exploitative and to the advantage of the elite to such an extent that peasants are an internal colony. The analysis is informed by critical anti-colonial perspectives that observe the hegemonic tendencies of global and local capital in collusion with dictatorial elite nationalists. By use of a critical interpretive case study of purposefully sampled students and other relevant members of the university community from one public university, disturbing student experiences were excavated. Student narratives and experiences were analyzed using the constant comparative method and led to the conclusion that there is internal colonialism in Zimbabwe where an alliance of the state and the local and global corporate world are colluding to maintain their economic and political dominance. The article challenges those in education and academics that there is need for the decolonization of education by first identifying contemporary hegemonic forces and recognizing students from the peasantry as victims of the emerging kleptocratic capitalism.

  10. Lessons in modularity: the evolutionary ecology of colonial invertebrates

    Directory of Open Access Journals (Sweden)

    Roger N. Hughes

    2005-06-01

    Full Text Available Benthic colonial invertebrates share with higher plants a modular construction and a sessile adult life. Both types of organism show parallel evolutionary responses to common selective forces, but in contrast to the long-established focus on plants, comparable study of colonial invertebrates has developed relatively recently, largely owing to the application of new techniques in image processing and molecular biology. Species whose life cycles are readily completed under laboratory conditions and whose colonies are easily propagated from cuttings provide powerful models for experimentally investigating fundamental evolutionary problems, including metabolic allometry, the manifestation of ageing and the origin of allorecognition systems. Free of the confounding influences of behavioural manipulation and costs of copulation, colonial invertebrates whose water-borne sperm fertilize retained eggs lend themselves well to the experimental study of cryptic female choice, sperm competition and sexual conflict. In these respects, it will be productive to adopt and extend theoretical frameworks developed for flowering plants to guide experimental investigation of modular animals. Since mate choice occurs at the cellular level in modular animals, reproductive isolation is uncorrelated with morphology and cryptic speciation is likely to be widespread.

    Full Text Available Resumo Atualmente, com o avanço da tecnologia de corte e solda, perfis de aço com aberturas sequenciais na forma circular, denominados perfis celulares, vêm sendo bastante utilizadas como vigas de edificações. A ABNT NBR 8800:2008 e as normas estrangeiras não abordam vigas de aço e vigas mistas de aço e concreto com perfil celular, o que contribui para que o seu uso seja limitado. Foi desenvolvido e aferido um programa computacional para o dimensionamento de vigas mistas de aço e concreto com perfil celular biapoiadas de acordo com duas metodologias distintas da literatura. Um estudo paramétrico abordando vigas mistas com perfis celulares obtidos de dois perfis I de aço laminados comerciais foi realizado. Nesse estudo, a influência dos parâmetros geométricos do perfil celular e do comprimento do vão da viga na resistência e na forma de colapso foi analisada. Foi possível concluir que em muitas situações o uso de vigas mistas com perfil celular é vantajoso em relação às vigas mistas de alma cheia.

Analisou-se uma amostra de 313 empresas listadas na Bovespa de 2000 a 2005. Os resultados indicam que unicamente as empresas de menor tamanho na amostra, de lucratividade negativa e baixo crescimento, apresentam aderência (fraca às previsões da POT. Assim, essa teoria não pode ser considerada uma teoria geral para explicar a estrutura de capital das empresas.

    The success of an ant colony depends on the simultaneous presence of reproducing queens and nonreproducing workers in a ratio that will maximize colony growth and reproduction. Despite its presumably crucial role, queen–worker caste ratios (the ratio of adult queens to workers) and the factors...... affecting this variable remain scarcely studied. Maintaining polygynous pharaoh ant (Monomorium pharaonis) colonies in the laboratory has provided us with the opportunity to experimentally manipulate colony size, one of the key factors that can be expected to affect colony level queen–worker caste ratios...... species with budding colonies may adaptively adjust caste ratios to ensure rapid growth....

    Diverse colony morphologies are a hallmark of Burkholderia pseudomallei recovered from infected patients. We observed that stresses that inhibit aerobic respiration shifted populations of B. pseudomallei from the canonical white colony morphotype toward two distinct, reversible, yet relatively stable yellow colony variants (YA and YB). As accumulating evidence supports the importance of B. pseudomallei enteric infection and gastric colonization, we tested the response of yellow variants to hypoxia, acidity, and stomach colonization. Yellow variants exhibited a competitive advantage under hypoxic and acidic conditions and alkalized culture media. The YB variant, although highly attenuated in acute virulence, was the only form capable of colonization and persistence in the murine stomach. The accumulation of extracellular DNA (eDNA) was a characteristic of YB as observed by 4',6-diamidino-2-phenylindole (DAPI) staining of gastric tissues, as well as in an in vitro stomach model where large amounts of eDNA were produced without cell lysis. Transposon mutagenesis identified a transcriptional regulator (BPSL1887, designated YelR) that when overexpressed produced the yellow phenotype. Deletion of yelR blocked a shift from white to the yellow forms. These data demonstrate that YB is a unique B. pseudomallei pathovariant controlled by YelR that is specifically adapted to the harsh gastric environment and necessary for persistent stomach colonization. Seemingly uniform populations of bacteria often contain subpopulations that are genetically identical but display unique characteristics which offer advantages when the population is faced with infrequent but predictable stresses. The pathogen Burkholderia pseudomallei is capable of forming several reversible colony types, and it interconverted between one white type and two yellow types under certain environmental stresses. The two yellow forms exhibited distinct advantages in low-oxygen and acidic environments. One yellow

    During June and July of 2009, sudden deaths, tremulous movements and population declines of adult honey bees were reported by the beekeepers in the region of Peloponnesus (Mt. Mainalo), Greece. A preliminary study was carried out to investigate these unexplained phenomena in this region. In total, 37 bee samples, two brood frames containing honey bee brood of various ages, eight sugar samples and four sugar patties were collected from the affected colonies. The samples were tested for a range of pests, pathogens and pesticides. Symptomatic adult honey bees tested positive for Varroa destructor, Nosema ceranae, Chronic bee paralysis virus (CBPV), Acute paralysis virus (ABPV), Deformed wing virus (DWV), Sacbrood virus (SBV) and Black queen cell virus (BQCV), but negative for Acarapis woodi. American Foulbrood was absent from the brood samples. Chemical analysis revealed that amitraz, thiametoxan, clothianidin and acetamiprid were all absent from symptomatic adult bees, sugar and sugar patty samples. However, some bee samples, were contaminated with imidacloprid in concentrations between 14 ng/g and 39 ng/g tissue. We present: the infection of Greek honey bees by multiple viruses; the presence of N. ceranae in Greek honey bees and the first record of imidacloprid (neonicotonoid) residues in Greek honey bee tissues. The presence of multiple pathogens and pesticides made it difficult to associate a single specific cause to the depopulation phenomena observed in Greece, although we believe that viruses and N. ceranae synergistically played the most important role. A follow-up in-depth survey across all Greek regions is required to provide context to these preliminary findings. Copyright © 2010 Elsevier Inc. All rights reserved.

    1992-09-01

    This document describes the environmental monitoring program at the Colonie Interim Storage Site (CISS) and surrounding area, implementation of the program, and monitoring results for 1991. Environmental monitoring at CISS began in 1984 when Congress added the site to the US Department of Energy's Formerly Utilized Sites Remedial Action Program. CISS property and surrounding areas were radioactively contaminated by operations conducted by National Lead Industries, which manufactured various components from uranium and thorium from 1958 to 1984. The environmental monitoring program at CISS includes sampling networks for external gamma radiation exposure and for radium-226, thorium-232, and total uranium concentrations in surface water, sediment, and groundwater. Additionally, several nonradiological parameters are measured in groundwater. In 1992 the program will also include sampling networks for radioactive and chemical contaminants in stormwater to meet permit application requirements under the Clean Water Act. Monitoring results are compared with applicable Environmental Protection Agency (EPA) standards, DOE derived concentration guides (DCGs), dose limits, and other requirements in DOE.orders. Environmental standards are established to protect public health and the environment. Results of environmental monitoring during 1991 indicate that average concentrations of radioactive contaminants of concern were well below applicable standards and DCGS. Concentrations of some chemical contaminants in groundwater were above-the New York State Department of Environmental Conservation (Class GA) and EPA guidelines for drinking water. The potential annual radiation exposure (excluding background) calculated for a hypothetical maximally exposed individual is 0.23 mrem (milliroentgen equivalent man), which is less than an individual would receive while traveling in an airplane at 12,000 meters (39,000 feet) for one hour

  20. FluG affects secretion in colonies of Aspergillus niger.

    Colonies of Aspergillus niger are characterized by zonal heterogeneity in growth, sporulation, gene expression and secretion. For instance, the glucoamylase gene glaA is more highly expressed at the periphery of colonies when compared to the center. As a consequence, its encoded protein GlaA is mainly secreted at the outer part of the colony. Here, multiple copies of amyR were introduced in A. niger. Most transformants over-expressing this regulatory gene of amylolytic genes still displayed heterogeneous glaA expression and GlaA secretion. However, heterogeneity was abolished in transformant UU-A001.13 by expressing glaA and secreting GlaA throughout the mycelium. Sequencing the genome of UU-A001.13 revealed that transformation had been accompanied by deletion of part of the fluG gene and disrupting its 3' end by integration of a transformation vector. Inactivation of fluG in the wild-type background of A. niger also resulted in breakdown of starch under the whole colony. Asexual development of the ∆fluG strain was not affected, unlike what was previously shown in Aspergillus nidulans. Genes encoding proteins with a signal sequence for secretion, including part of the amylolytic genes, were more often downregulated in the central zone of maltose-grown ∆fluG colonies and upregulated in the intermediate part and periphery when compared to the wild-type. Together, these data indicate that FluG of A. niger is a repressor of secretion.

  1. The global distribution of ammonia emissions from seabird colonies

    Seabird colonies represent a significant source of atmospheric ammonia (NH3) in remote maritime systems, producing a source of nitrogen that may encourage plant growth, alter terrestrial plant community composition and affect the surrounding marine ecosystem. To investigate seabird NH3 emissions on a global scale, we developed a contemporary seabird database including a total seabird population of 261 million breeding pairs. We used this in conjunction with a bioenergetics model to estimate the mass of nitrogen excreted by all seabirds at each breeding colony. The results combined with the findings of mid-latitude field studies of volatilization rates estimate the global distribution of NH3 emissions from seabird colonies on an annual basis. The largest uncertainty in our emission estimate concerns the potential temperature dependence of NH3 emission. To investigate this we calculated and compared temperature independent emission estimates with a maximum feasible temperature dependent emission, based on the thermodynamic dissociation and solubility equilibria. Using the temperature independent approach, we estimate global NH3 emissions from seabird colonies at 404 Gg NH3 per year. By comparison, since most seabirds are located in relatively cold circumpolar locations, the thermodynamically dependent estimate is 136 Gg NH3 per year. Actual global emissions are expected to be within these bounds, as other factors, such as non-linear interactions with water availability and surface infiltration, moderate the theoretical temperature response. Combining sources of error from temperature (±49%), seabird population estimates (±36%), variation in diet composition (±23%) and non-breeder attendance (±13%), gives a mid estimate with an overall uncertainty range of NH3 emission from seabird colonies of 270 [97-442] Gg NH3 per year. These emissions are environmentally relevant as they primarily occur as "hot-spots" in otherwise pristine environments with low anthropogenic

  2. Ant Larval Demand Reduces Aphid Colony Growth Rates in an Ant-Aphid Interaction

    Full Text Available Ants often form mutualistic interactions with aphids, soliciting honeydew in return for protective services. Under certain circumstances, however, ants will prey upon aphids. In addition, in the presence of ants aphids may increase the quantity or quality of honeydew produced, which is costly. Through these mechanisms, ant attendance can reduce aphid colony growth rates. However, it is unknown whether demand from within the ant colony can affect the ant-aphid interaction. In a factorial experiment, we tested whether the presence of larvae in Lasius niger ant colonies affected the growth rate of Aphis fabae colonies. Other explanatory variables tested were the origin of ant colonies (two separate colonies were used and previous diet (sugar only or sugar and protein. We found that the presence of larvae in the ant colony significantly reduced the growth rate of aphid colonies. Previous diet and colony origin did not affect aphid colony growth rates. Our results suggest that ant colonies balance the flow of two separate resources from aphid colonies- renewable sugars or a protein-rich meal, depending on demand from ant larvae within the nest. Aphid payoffs from the ant-aphid interaction may change on a seasonal basis, as the demand from larvae within the ant colony waxes and wanes.

    1996-05-01

    Residual radioactive material guidelines for uranium in soil were derived for the Colonie site located in Colonie, New York. This site has been designated for remedial action under the Formerly Utilized Sites Remedial Action Program (FUSRAP) of the U.S. Department of Energy (DOE). The site became contaminated with radioactive material as a result of operations conducted by National Lead (NL) Industries from 1958 to 1984; these activities included brass foundry operations, electroplating of metal products, machining of various components using depleted uranium, and limited work with small amounts of enriched uranium and thorium. The Colonie site comprises the former NL Industries property, now designated the Colonie Interim Storage Site (CISS), and 56 vicinity properties contaminated by fallout from airborne emissions; 53 of the vicinity properties were previously remediated between 1984 and 1988. In 1984, DOE accepted ownership of the CISS property from NL Industries. Residual radioactive material guidelines for individual radionuclides and total uranium were derived on the basis of the requirement that the 50-year committed effective dose equivalent to a hypothetical individual who lives or works in the immediate vicinity of the site should not exceed a dose of 30 mrem/yr following remedial action for the current use and likely future use scenarios or a dose of 100 mrem/yr for less likely future use scenarios. The DOE residual radioactive material guideline computer code, RESRAD, was used in this evaluation; RESRAD implements the methodology described in the DOE manual for establishing residual radioactive material guidelines

  11. Investigation of multimodal forward scatter phenotyping from bacterial colonies

    Kim, Huisung

    A rapid, label-free, and elastic light scattering (ELS) based bacterial colony phenotyping technology, bacterial rapid detection using optical scattering technology (BARDOT) provides a successful classification of several bacterial genus and species. For a thorough understanding of the phenomena and overcoming the limitations of the previous design, five additional modalities from a bacterial colony: 3D morphology, spatial optical density (OD) distribution, spectral forward scattering pattern, spectral OD, and surface backward reflection pattern are proposed to enhance the classification/identification ratio, and the feasibilities of each modality are verified. For the verification, three different instruments: integrated colony morphology analyzer (ICMA), multi-spectral BARDOT (MS-BARDOT) , and multi-modal BARDOT (MM-BARDOT) are proposed and developed. The ICMA can measure 3D morphology and spatial OD distribution of the colony simultaneously. A commercialized confocal displacement meter is used to measure the profiles of the bacterial colonies, together with a custom built optical density measurement unit to interrogate the biophysics behind the collective behavior of a bacterial colony. The system delivers essential information related to the quantitative growth dynamics (height, diameter, aspect ratio, optical density) of the bacterial colony, as well as, a relationship in between the morphological characteristics of the bacterial colony and its forward scattering pattern. Two different genera: Escherichia coli O157:H7 EDL933, and Staphylococcus aureus ATCC 25923 are selected for the analysis of the spatially resolved growth dynamics, while, Bacillus spp. such as B. subtilis ATCC 6633, B. cereus ATCC 14579, B. thuringiensis DUP6044, B. polymyxa B719W, and B. megaterium DSP 81319, are interrogated since some of the Bacillus spp. provides strikingly different characteristics of ELS patterns, and the origin of the speckle patterns are successfully correlated with

    Full Text Available El artículo sintetiza algunas conclusiones a las que han llegado movimientos sociales y académicos en las últimas dos décadas al reflexionar sobre la globalización y sus implicaciones; el modelo dominante, basado en las nociones de "desarrollo" y "modernidad", ha entrado en crisis. Por lo tanto, se hace necesario avanzar en una transición cultural que se pueda comprender como un cambio de época y no sólo como una época de cambios. Para llevar a cabo esta transformación, se deben resolver las con-tradicciones existentes entre el neodesarrollismo y el postdesarrollo, por supuesto, a favor de éste último.

  15. A child of the empire: British sociology and colonialism, 1940s-1960s.

    British sociology was established as an academic discipline between 1945 and 1965, just as the British Empire was gearing up for a new phase of developmental colonialism backed by the social and other sciences. Many parts of the emerging sociological discipline became entangled with colonialism. Key themes and methods in sociology and the staff of sociology departments emerged from this colonial context. Historians have tended to place postwar British sociology in the context of expanding higher education and the welfare state, and have overlooked this colonial constellation. The article reconstructs this forgotten moment of disciplinary founding and explores three of the factors that promoted colonial sociology: the Colonial Social Science Research Council, the so-called Asquith universities, and the social research institutes in the colonies; and the involvement of sociologists from the London School of Economics in training colonial officials. © 2013 Wiley Periodicals, Inc.

    Full Text Available The Spanish Second Republic set aside a big amount of resources, both human and economic, to survey the colonies. The consecutive republican governments kept a strong continuity on the schemes for colonial cartography, with no significant changes over the plans established in past periods. Cartographic work was focused in Morocco’s territory, and was carry out by a military unit named Comisión Geográfíca de Marruecos y Límites (Morocco’s Geographical Commission. This paper, built on primary sources, examines the institutional framework of Spanish colonial cartography during the republican period, identifies the leading mapmakers, and discusses the main cartographic surveys.

    La Segunda República dedicó cuantiosos recursos, económicos y humanos, a la cartografía de las posesiones coloniales. Los sucesivos gobiernos republicanos mantuvieron una fuerte continuidad, organizativa y funcional, en el ámbito de la cartografía colonial, sin que se detecte ningún cambio significativo respecto a los planes trazados en etapas anteriores. La actividad cartográfica continuó centrada en el territorio de Marruecos, y fue protagonizada por una unidad dependiente del Ministerio de la Guerra, la Comisión Geográfica de Marruecos y Límites. En este trabajo, que se apoya en fuentes primarias, se ofrece una descripción del marco institucional de la cartografía colonial durante el período republicano, se identifica a sus artífices, y se da cuenta de los levantamientos cartográficos realizados. [fr] La Deuxième République a consacré nombreux ressources, économiques et humains, à la cartographie des possessions coloniales. Les successifs gouvernements républicains ont tenu une forte continuité, d’organisation et fonctionnelle, dans le domaine de la cartographie coloniale, sans qu’on ne puisse détecter aucun changement significatif en relation aux plans tracés en étapes antérieures.

    Full Text Available El mundo del flamenco, tan acostumbrado a contemplar la historia del género como una sucesión de nombres distinguidos que, por su significación expresiva o por su carácter de maestría incontestable, simbolizan una época, olvida con frecuencia el universo en que esa constelación de estrellas irradia su luminosidad más intensa, esto es, relega a un rol de menor importancia el ámbito en que se desarrollaron unos talentos especiales que, a lapostre, describirían situaciones y formas que el tiempo estimaría de verdadera trascendencia. Sin ánimo de caer en un determinismo localista demasiado forzoso, justo es decir que uno de los más grandes milagros de la música flamenca, se llama Sevilla, su barrio de Triana y muchos pueblos de la provincia. Una unidad demográfica que ofrece en grado sumo el origen de la complacencia en los goces de los sentidos.

    Full Text Available Que la información de noticiero de radio y televisión oficiales en la mayoría de los países latinoamericanos, no brilla precisamente por su imparcialidad. Además los noticieros con información sobre actividades, políticas y criterios de entidades públicas difunden un punto de vista que no es necesariamente compartido por sectores políticos y económicos de la sociedad civil y que tampoco refleja necesariamente lo que ocurre en un país. Este es un hecho comprobado hasta la saciedad y constituye un problema que exigirá que las contribuciones al programa común se distingan por una excelente selección representativa del multifacético acontecer diario de una nación. Las estadísticas de otros sistemas como EUROVISION y ASIAVISION muestran que una noticia se difunde más si es oportuna - "caliente"-, objetiva y presentada con calidad.
