    Full Text Available Abstract Toxoplasmosis is an infectious, zoonotic and parasitic disease, caused by Toxoplasma gondii. In this manucript, two cases of infection with T. gondii in captive animals from a zoological park in the central region of Chile are described. One case was a red kangaroo (Macropus rufus, which is highly susceptible to the infection, and the other was a Patagonian mara (Dolichotis patagonum, a rodent in which there is no previous report of the infection. Both animals had myocarditis, with the presence of intralesional tachizoites and cysts suggestive of infection with T. gondii. This infection was confirmed by immunohistochemistry in both animals. The origin of the infection is unknown, but it is likely that free ranging domestic felines were associated with the dissemination of the parasites. This highlights the importance of controlling the domestic animal populations in zoological parks. To the best of our knowledge, this is the first time that T. gondii infection is described in a Patagonian mara, adding a new host for this infectious agent.

    Full Text Available Histoplasma capsulatum was isolated from the spleen of a first infected mara (Dolichotis patagonum and from a second mara's liver and adrenal gland, both in the same colony at the Africam Safari, Puebla, Mexico. Studies of H. capsulatum isolates, using nested-PCR of a 100-kDa protein coding gene (Hcp100 fragment and a two-primer RAPDPCR method, suggest that these isolates were spreading in the environment of the maras' enclosure. By using a Dot- ELISA method, sera from mice inoculated with three homogenates of soil samples from the maras' enclosed space developed positive brown spot reactions to a purified H. capsulatum antigen, which identified the probable source of the maras' infection.Histoplasma capsulatum fue aislado del bazo de una primera mara (Dolichotis patagonum infectada y del hígado y la glándula suprarrenal de un segundo ejemplar, ambos de la misma colonia en el Africam Safari, Puebla, México. Los estudios de los aislamientos de H. capsulatum mediante PCR anidada para un fragmento del gen Hcp100 que codifica una proteína de 100 kDa y RAPD-PCR empleando doble iniciador sugieren que estos aislamientos estaban dispersos en el ambiente del refugio de las maras. Los sueros de ratones inoculados con tres homogenatos de muestras de suelo del refugio desarrollaron reacciones positivas a un antígeno purificado de H. capsulatum (manchas color castaño oscuro por el método de Dot-ELISA; con lo cual se identificó la probable fuente de infección de las maras.

    Full Text Available As a result of his consistent attitude as citizen and doctor and his “liberal spirit”, Marañón has gone down in the history of the twentieth century as an archetype. Marañón was, above all, a moralist in the Kantian sense, an autonomous person not governed by external criteria but by duty; a thinker convinced of the transforming role of the positive sciences, towards a happier and more just society through a deep intellectual reform. Marañón, like Fernando de los Rios, integrated Kraussism, neo-Kantianism and socialism and from this ideological platform sought the necessary moral change in the Spanish people.Marañón ha pasado a la historia del siglo XX como arquetipo, debido a su actitud coherente y a su “talante liberal”. Marañón fue, sobre todo, un moralista en el sentido kantiano. Una persona autónoma que no se rigió por criterios externos, sino por deber; un convencido del papel transformador de las ciencias positivas en pos de una sociedad más feliz y más justa gracias a una profunda reforma intelectual. Marañón, como Fernando de los Ríos, integró krausismo, neokantismo y socialismo y desde esa plataforma ideológica, propugnó el necesario cambio moral del pueblo español.

    The aim of this study is to offer a critical opinion of an important chapter in the bibliography of Gregorio Marańon, the key figure of Spanish Medicine in the period between the wars. The biography of the philosopher Amiel, of the emperor romano Tiberio and of the Castilian king Enrique IV are carefully studied. In the research the interpretative criteria offered by Medicine and Psychology have been used. His more important works rebuild the political labor of El Conde-Duque de Olivares, "valido" of Felipe IV, and of Antonio Pérez, registrar of Felipe II. In both works Marañón reconstruct, with exhaustive critical bibliography and documentary support, a historical period covering the last decades of the 16th century and the first half of the 17th. Through his works, Gregorio Marañón proves the efficient value of the use of medical and psychological knowledge in historical research.

    Canine distemper virus (CDV) has been implicated in some recent deaths of lions, which showed clinical signs of distemper, in the the Serengeti plain. Similar clinical findings have since been reported in lions of the Masai Mara. Fifty-five per cent of serum samples obtained from wild lions of the Masai Mara have been found to contain neutralising antibody to CDV, indicating that they had been exposed to the virus. Adult orphan lions kept in captivity, were vaccinated with the live attenuated Onderstepoort strain of CDV. The results indicated that the vaccine is both safe and immunogenic, and may be potentially useful for the prophylactic vaccination of lions at high risk.

    In the oil industry, the environmental impact assessment of an accident is both multi and interdisciplinary and goes through several approaches and depths. Due to the enormous complexity of the environmental analyses issues, mainly for being a science in development and not technological consensus, a macro methodology is presented for the purpose of identify areas that can be impacted by pipeline leakages and recommend improvements are applicable working as a table top response plan. The methodology of the Environmental Risk Mapping-MARA for pipelines rows, describes its concept and justifies the adoption of the environmental mapping during Risk Analyses studies, for PETROBRAS/TRANSPETRO new and existing pipelines. The development of this methodology is justified by the fact that it is a practical tool for identification, analysis and categorization of the more vulnerable environmental elements along a pipeline row and vicinities, during simulated occurrence of accidental spills of hydrocarbons in the environment. This methodology is a tool that allows Environmental Agencies and PETROBRAS a better way to manage in advance the Company emergencies. (author)

  10. Model of transcriptional activation by MarA in Escherichia coli.

    Wall, Michael E; Markowitz, David A; Rosner, Judah L; Martin, Robert G

    2009-12-01

    The AraC family transcription factor MarA activates approximately 40 genes (the marA/soxS/rob regulon) of the Escherichia coli chromosome resulting in different levels of resistance to a wide array of antibiotics and to superoxides. Activation of marA/soxS/rob regulon promoters occurs in a well-defined order with respect to the level of MarA; however, the order of activation does not parallel the strength of MarA binding to promoter sequences. To understand this lack of correspondence, we developed a computational model of transcriptional activation in which a transcription factor either increases or decreases RNA polymerase binding, and either accelerates or retards post-binding events associated with transcription initiation. We used the model to analyze data characterizing MarA regulation of promoter activity. The model clearly explains the lack of correspondence between the order of activation and the MarA-DNA affinity and indicates that the order of activation can only be predicted using information about the strength of the full MarA-polymerase-DNA interaction. The analysis further suggests that MarA can activate without increasing polymerase binding and that activation can even involve a decrease in polymerase binding, which is opposite to the textbook model of activation by recruitment. These findings are consistent with published chromatin immunoprecipitation assays of interactions between polymerase and the E. coli chromosome. We find that activation involving decreased polymerase binding yields lower latency in gene regulation and therefore might confer a competitive advantage to cells. Our model yields insights into requirements for predicting the order of activation of a regulon and enables us to suggest that activation might involve a decrease in polymerase binding which we expect to be an important theme of gene regulation in E. coli and beyond.

    A low-energy radioactive ion beam facility for the production and study of nuclei produced close to the proton drip line is under development at the Accelerator Laboratory of the University of Jyväskylä, Finland. The facility will take advantage of the mass selectivity of the recently commissioned MARA vacuum-mode mass separator. The ions selected by MARA will be stopped and thermalised in a small-volume gas cell prior to extraction and further mass separation. The gas cell design allows for resonance laser ionisation/spectroscopy both in-gas-cell and in-gas-jet. The facility will include experimental setups allowing ion counting, mass measurement and decay spectroscopy.

    Full Text Available Athough eugenic ideas were by no means alien to Spanish thought before the 20th century, it is only by the end of the 1920s and the beginning of the 1930s that the first steps towards an institutionalization of Eugenics in Spain were actually taken. In this period, Dr. Marañón produced a number of interesting writings, mostly of a minor or occasional nature, on Eugenic subjects. Marañón was by then one of the leading intellectuals of his generation. His great reputation as a physician and as a man of science was only equal to his wide acknowledgement as a writer on general social issues, which makes his contribution to Eugenics particularly significant. In spite of the attention always paid by Marañón to Eugenic issues, he never published a proper treatise on the subject. His views must therefore be gathered from very scattered sources. The aim of this paper is to accomplish such a task, and thus draw an outline of Marañón's eugenic program by emphasizing those aspects (biological, economic, political, educational and moral he mainly dealt with. It is there thereby sought to unearth a key contribution to the development of eugenic ideas in early 20th century.

    A finales de 1920 y comienzos de 1930 tiene lugar uno de los primeros intentos de institucionalización de la Eugenesia en España. Son éstos también los años en que Marañón, por entonces una de las figuras públicas de mayor relieve y prestigio de todo el país, escribe sobre el tema. Su gran reputación no sólo como médico y hombre de ciencia, sino también como escritor y conferenciante sobre asuntos de amplio alcance social, dotó a sus escritos de una eficacia divulgadora incomparable, lo que hace enormemente significativa su defensa del ideal eugénico. A pesar de la importancia que atribuyó siempre a la Eugenesia, Marañón no llegó a escribir nunca un tratado sobre el tema. Pero los escritos dispersos en que se ocupa de él contienen ideas que, a nuestro

    La violencia es uno de los grandes problemas sociales que afecta a la sociedad latinoamericana. En concreto, en El Salvador, requieren de especial atención las pandillas juveniles o maras al ser producto del fracaso de una sociedad voraz e injusta que crea las condiciones necesarias para empujar hacia ellas a los y las jóvenes. Éstos, a su vez, se destruyen socialmente a sí mismos y a sus comunidades. Por tanto, romper los círculos de la violencia demanda propuestas contrarias al modelo repre...

  19. Le Docteur Gregorio Marañón, ou la plume militante de l’endocrinologue

    Directory of Open Access Journals (Sweden)

    2010-07-01

    Full Text Available Jouissant dès le début des années vingt d’un grand prestige dû à ses travaux sur les glandes endocrines, le Docteur Gregorio Marañón (1887-1960 s’engagea de tout son poids dans le débat social, mettant son autorité de médecin reconnu au service de la lutte contre la misère. Dans cette même perspective, c’est en endocrinologue convaincu de « l’intelligence vitale » du système hormonal, qu’il prit position en faveur de la limitation des naissances et de la reconnaissance de lasexualité féminine, dans un contexte où cette question était au cœur des conflits idéologiques qui traversaient la société espagnole entre 1920 et 1936. Porté par un important courant de juristes, de médecins, d’écrivains libéraux qui militaient en faveur du birth control et d’une sexualité assumée, le prestigieux docteur Marañón apportait sa légitimité scientifique à la démarche. Or, les thèses de Marañón, promises à une longue et faussement paradoxale postérité sous le franquisme, reposent sur un double postulat qui affirme une certaine forme de déterminisme biologique des comportements humains, et qui affirme aussi, à l’instar des théories freudiennes, l’importance décisive de la sexualité dans ces comportements. On tentera de montrer comment les théories de l’endocrinologue libéral ont pu, dans les années 40, être instrumentalisées pour apporter leur caution scientifique à la morale sexuelle imposée par le franquisme. Les théories de Marañón ont en effet fourni aux intellectuels organiques du régime franquiste tant d’arguments pour sa politique nataliste et pour la relégation des femmes dans le domaine privé du foyer que ses écrits sont incontournables pour quiconque se penche sur cet aspect de l’histoire de la dictature.El Doctor Gregorio Marañón (1887-1960, que gozaba en los años veinte de un gran prestigio debido a sus trabajos sobre endocrinología, se comprometió sin reparos en el

    The objective of this study is to evaluate the effect of timing on Mandibular Anterior Repositioning Appliance (MARA) and fixed appliance treatment of Class II malocclusion in a prospective clinical trial. The treated sample consisted of 51 consecutively treated patients at prepubertal (n = 21), pubertal (n = 15), and postpubertal (n = 15) stages of development. Control groups for the three treated groups were generated from growth data of untreated Class II subjects. Lateral cephalograms were digitized and superimposed via cephalometric software at T1 (pre-treatment) and T2 (after comprehensive treatment). The T1-T2 changes in the treated groups were compared to those in their corresponding control groups with Mann-Whitney tests with Bonferroni correction. Mandibular elongation was greater at the pubertal stage (Co-Gn +2.6 mm, with respect to controls). Headgear effect on the maxilla was greater in the pre-peak sample (Co-A -1.9 mm, with respect to controls). Dentoalveolar compensations (proclination of lower incisors, extrusion and mesialization of lower molars, and reduction in the overbite) were significant in the pre-peak and post-peak groups. Optimal timing for Class II treatment with MARA appliance is at the pubertal growth spurt, with enhanced mandibular skeletal changes and minimal dentoalveolar compensations.

  1. Modelling nitrogen transformation and removal in mara river basin wetlands upstream of lake Victoria

    2018-06-01

    Lake Victoria, the largest lake in Africa, is a resource of social-economic potential in East Africa. This lake receives water from numerous tributaries including Mara River, which contributes about 4.8% of the total Lake water inflow. Unfortunately, Mara River basin faces environmental problems because of intensive settlement, agriculture, overgrazing in the basin and mining activities, which has lead to water pollution in the river, soil erosion and degradation, decreased soil fertility, loss of vegetation cover, decreased water infiltration capacity and increased sedimentation. One of the pollutants carried by the river includes nitrogen, which has contributed to ecological degradation of the Lake Victoria. Therefore this research work was intended to determine the effectiveness of Mara River wetland for removal of nitrogen and to establish nitrogen removal mechanisms in the wetland. To predict nitrogen removal in the wetland, the dynamics of nitrogen transformation was studied using a conceptual numerical model that takes into account of various processes in the system using STELLA II version 9.0®2006 software. Samples of model input from water, plants and sediments were taken for 45 days and were analyzed for pH, temperature, and DO in situ and chemical parameters such as NH3-N, Org-N, NO2-N, and NO3-N were analyzed in the laboratory in accordance with Standard methods. For plants, the density, dominance, biomass productivity and TN were determined and for sediments TN was analyzed. Inflow into the wetland was determined using stage-discharge relationship and was found to be 734,400 m3/day and the average wetland volume was 1,113,500 m3. Data collected by this study were used for model calibration of nitrogen transformation in this wetland while data from another wetland were used for model validation. It was found that about 37.8% of total nitrogen was removed by the wetland system largely through sedimentation (26.6%), plant uptake (6.6%) and

    To the best of our knowledge, no previous study regarding the serum telomerase levels in Maras powder users (MPUs) has been founded. The aim of the current study was to investigate serum telomerase levels in smokers and MPUs. The study was carried out with 98 patients (36 MPUs, 32 smokers and 30 non-smokers). Blood samples were collected, and after having measured the serum telomerase and malondialdehyde (MDA) levels of the patients, comparison were made between the groups. It has been observed that the serum telomerase and MDA levels of smokers (pnon-smoker control subjects. In addition, the levels of serum telomerase and MDA were observed to be higher in the MPU group compared to those of the smoker group (psmokers. In this context, it may be useful to further measure and assess telomerase activity in such patients in order to better determine the harmful effects associated with these habits.

  4. Marañón and historical social psychology: some theoretical questions.

    Directory of Open Access Journals (Sweden)

    Almagro González, Andrés

    2008-11-01

    Full Text Available If one takes a multidisciplinary, integrative perspective on historical social psychology, one sees that it is a vital thread not only in the theoretical weave of social psychology as such, but in any social science which studies the social being. The multidisciplinary character of historical social psychology is friendly to authors and ideas from other domains of knowledge. Marañón's insights suggest interesting ways of answering the main questions that arise in historical social psychology. The application of his method, as I shall try to show, can orient to us towards a social psychology concerned not only with the here and now of its object of study, but also with the way in which it has evolved through history.

    OmpW is a minor porin whose biological function has not been clearly defined. Evidence obtained in our laboratory indicates that in Salmonella enterica serovar Typhimurium the expression of OmpW is activated by SoxS upon exposure to paraquat and it is required for resistance. SoxS belongs to the AraC family of transcriptional regulators, like MarA and Rob. Due to their high structural similarity, the genes under their control have been grouped in the mar/sox/rob regulon, which presents a DNA-binding consensus sequence denominated the marsox box. In this work, we evaluated the role of the transcription factors MarA, SoxS and Rob of S. enterica serovar Typhimurium in regulating ompW expression in response to menadione. We determined the transcript and protein levels of OmpW in different genetic backgrounds; in the wild-type and Δrob strains ompW was upregulated in response to menadione, while in the ΔmarA and ΔsoxS strains the induction was abolished. In a double marA soxS mutant, ompW transcript levels were lowered after exposure to menadione, and only complementation in trans with both genes restored the positive regulation. Using transcriptional fusions and electrophoretic mobility shift assays with mutant versions of the promoter region we demonstrated that two of the predicted sites were functional. Additionally, we demonstrated that MarA increases the affinity of SoxS for the ompW promoter region. In conclusion, our study shows that ompW is upregulated in response to menadione in a cooperative manner by MarA and SoxS through a direct interaction with the promoter region.

    Full Text Available Marañón’s work, as a whole, is truly complex. After a preliminary, partial reading, the questions that arise are numerous and varied. The aim of this article is to analyse some of the wealth of the medical facets of these works by following some of the threads which are repeated in the literature on the author. His medical works, within the context of western medicine of the time, are still analysed from a perspective of a series of clichés. Actually from our point of view, his work is the result of a peculiar construction, based on both medical practice and personal theoretical principles which led to a model of medicine similar to that of the great reformers within the framework which Laín Entralgo has termed “present medicine”.La obra de Marañón, en su conjunto, es verdaderamente compleja. Después de una primera lectura parcial la cantidad de interrogantes que plantea son muchos y variados, pero siguiendo unos pocos hilos conductores, que se repiten, podemos analizar su riqueza. Este es el objetivo del presente trabajo limitándonos a su faceta de médico. Su obra médica, en el conjunto de la medicina occidental del momento, sigue valorándose partiendo de una serie de tópicos. A nuestro parecer, es el resultado de una elaboración peculiar desde la clínica, y partiendo de unos supuestos personales; dando lugar a un modelo de medicina coincidente, en gran medida, con el de los grandes reformistas de lo que Laín Entralgo ha llamado “medicina actual”.

    Full Text Available Maquiavelo aconsejaba a los príncipes que se reservaran para sí la disposición de las materias de gracia. Este principio nunca fue olvidado por los reyes castellanos que consideraron el derecho de perdonar como una regalía. A lo largo del Antiguo Régimen se concedieron perdones reales por motivos diversos: políticos, religiosos, acontecimientos cortesanos, triunfos militares de la monarquía, o merced especial que el soberano deseó hacer a algún subdito. Por el número de afectados pueden clasificarse en generales, si absuelven a un colectivo de reos, o particulares, cuando el agraciado es uno solo. Los generales se regulaban por cédula específica que el rey despachaba al efecto. Su cumplimiento era vigilado por comisiones formadas por miembros de la Cámara, y los aspirantes a sus beneficios no necesitaban presentar solicitud personal ante ningún consejo regio, sino que siendo el caso de los incluidos en la cédula, las justicias de la causa se encargaban de su ejecución. Por está razón este tipo de indultos no han dejado huella en los archivos centrales, salvo las cédulas de concesión. Por el contrario, los individuales eran despachados por la Cámara en nombre del rey después de estudiar los autos procesales y han dejado en los archivos de la corona miles de testimonios. Estos van a ser el objeto de nuestro estudio.

    Full Text Available A temperatura interna das câmaras e o teor de água das sementes podem influenciar os resultados obtidos no teste de envelhecimento acelerado (EA e, consequentemente, sua interpretação. O trabalho foi desenvolvido com o objetivo de avaliar o efeito de diferentes teores iniciais de água de sementes de feijão nos resultados do teste de envelhecimento acelerado e as condições de temperatura e umidade relativa do ar no interior de duas câmaras de envelhecimento e das caixas plásticas (câmaras internas, durante a condução do teste. Utilizaram-se amostras de quatro lotes de sementes de feijão, cujo teor de água inicial foi ajustado para 8, 10 e 12%. As sementes foram submetidas ao envelhecimento em câmaras "jaquetada" de água e de germinação tipo BOD. Durante a realização do teste, foram monitorados, com um registrador de dados, os valores da temperatura e da umidade relativa do ar no interior das câmaras e das caixas plásticas, avaliados a cada 10 minutos, por sensores de cobre-constantan com bulbos seco e úmido, instalados no interior das mesmas. Verificou-se pequena variação de temperatura e umidade relativa do ar nas duas câmaras, sendo, porém, menor na "jaquetada". Em função da umidade relativa do ar na câmara "jaquetada" ter sido mais elevada, as sementes envelhecidas nessa câmara, apresentaram teor de água mais alto do que aquelas envelhecidas na BOD. Ambas as câmaras podem ser utilizadas para a realização do teste de envelhecimento acelerado de sementes de feijão.

    Full Text Available Os implantes em olhos fácicos apresentam-se como uma opção para a correção de altas ametropias. De acordo com sua localização podem ser classificados como de câmara anterior ou posterior, sendo que os primeiros subdividem-se em fixação iriana ou de suporte angular. Além da correção da miopia, as lentes de fixação iriana apresentam modelos para hipermétropes e astigmatas. Várias modificações no desenho das lentes foram propostas nas últimas décadas com a finalidade de reduzir complicações tardias, como a perda endotelial progressiva. Cuidados no intraoperatório devem ser tomados de forma a diminuir a perda endotelial aguda relacionada ao trauma. Avanços nos métodos de triagem pré-operatória também melhoraram a segurança do procedimento. A estimativa do poder dióptrico é baseada nos cálculos de Van der Heijde, sendo dependente da profundidade de câmara anterior, do equivalente esférico da refração e da média ceratométrica. Resultados a longo prazo demonstram a eficácia, previsibilidade e segurança do procedimento. Dependendo do modelo, além da possibilidade de perda endotelial, outras possíveis complicações incluem: irite, dispersão pigmentar, atrofia de íris, ovalização pupilar, rotação, descentração ou deslocamento da lente, hipertensão ocular e bloqueio pupilar. Modelos dobráveis atualmente disponíveis vêm apresentado resultados bastante promissores com redução da taxa de complicações.

    Full Text Available The maras Salvatrucha and Barrio 18 are two youth violent gangs with widespread presence in Central America and the United States. These gangs are attracting the attention of the scientific community because of their growing transnational links and the unusual levels of violence deployed. This article posits that the transnational expansion of the maras Salvatrucha and Barrio 18 is largely explained by their ability to generate an attractive identity framework of reference that resounds positively with the cultural background of young men of the Central American area. The policy of deportations of the United States government, the use of “iron hand” measures by some governments of the region and themigratory movements facilitated the diffusion of these identities across Central America throughout the last decade.

    Full Text Available En el derecho internacional es muy conocida la controversia sobre la existencia de un ordenamiento jurídico regulador del comercio internacional, también denominada doctrina de la lex mercatoria. Los diferentes argumentos de la doctrina en debate se presentan como irreconciliables, sin embargo, todos ellos se basan en postulados comunes. Este artículo está dedicado a explicar el consenso que aparece en la disputa y confrontarlo con la práctica arbitral internacional para averiguar si dicho acuerdo alcanza para justificar la lex. Con ese propósito analizamos los laudos de la Cámara de Comercio Internacional relativos a la elección del derecho aplicable al fondo del litigio y en los cuales los árbitros no contaban con facultades para pronunciarse ex aequo et bono. El resultado principal del estudio es que la existencia de la lex mercatoria no puede ser demostrada por la práctica arbitral bajo las condiciones comunesde la doctrina. La única certeza en los laudos es la remisión a los usos del comercio internacional, y el reconocimiento de principios generales establecidos en instrumentos universalmente aceptados. En conclusión, la lex mercatoria necesita fundamento dogmático y fáctico. Es la filosofía del derecho quien debe indagar la legitimidad y estructura del derecho comercial internacional.

    Full Text Available In 1988, the California state legislature passed the California Street Terrorism Enforcement and Prevention Act (STEP, which allowed courts to “enhance” the sentences of offenders who have been proven to "promote, further, or assist in any criminal conduct by gang members." It bundled together criminality, policing, and incarceration in ways that drew upon the fears of the black/latino Others that were imminent in panics surrounding the “crack epidemic” and inner-city crime. Jumping to April 2016, the Salvadoran government has passed strikingly similar legislation, which centers on reclassifying gang-associated crimes as terroristic; in essence under their new laws gang affiliation is a terrorist. This, too, has been enacted in the midst of panic about gang violence and low-level warfare between gangs and the Salvadoran state. The adoption of US-style anti-gang approaches by the Salvadoran government is not new. In 2003, the right-wing government passed mano dura [“iron fist”] policies that sought to address increases in gang associate crime with zero-tolerance, tough-on-crime measures. Law enforcement received expanded leeway to target and arrest gang members, especially those from Mara Salvatrucha 13 (MS-13 and Barrio 18. Despite the lack of sustained reductions in violent crime, the mano durapolicies have remained and will only be exacerbated by the new legislation.

    Full Text Available Aquí se exploran las representaciones colectivas, el escenario familiar, cotidiano y afectivo de los estudiantes de mediados de 1960 en la Universidad Nacional (UN en Bogotá, y de los primeros años de 1970 en la Universidad de Antioquia (UdeA, en Medellín. El objetivo: acercarse a la historia transcurrida tras las cámaras de la historiografía político-social tradicionalmente encargada del sujeto en cuestión, la cual creo un acervo, pero también un objeto desde una mirada particular. Las fuentes: dos novelas, Compañeros de viaje (1991 de Luis Fayad y El dedo índice de Mao (1993 de Juan Diego Mejía. El ejercicio permitió aproximarse a la escena privada y domestica estudiantil, reflexionar sobre el vínculo de esta con la vida pública y social y sobre la injerencia de las razones afectivas en los motivos de la vinculación o la militancia, así como interpretar la manera como significaron y enfrentaron el mundo en que vivieron, a partir de indicios y datos tipificados encontrados en las novelas. Finalmente, el artículo es una forma de demostrar y corroborar la eficacia del uso de la novela como fuente, que parece depender más de las capacidades del investigador que de las cualidades del material.

    Full Text Available The Kenyan government sees ecotourism as having the potential of becoming a moderately useful tool for locally directed and participatory rural development based on a rational utilization of environmental and cultural resources on which tourism relays on. We therefore need a better understanding of ecotourism’s impacts, and how those impacts are affected by various development and management strategies. Furthermore, ecotourism not only provides revenue and employment, but also causes undesirable environmental and social change. Unfortunately, these costs of ecotourism development are rarely evaluated in detail. If ecotourism is indeed promoting a region’s welfare, it is vital that apart from the economic potential, environmental and social costs that also need to be identified, these costs enter into any decisions about ecotourism development. This paper contributes to a greater understanding of the linkages between ecotourism and the economy from the Kenyan perspective. Research was undertaken in communities adjacent to Masai Mara and Amboseli area in Kenya. The study examined the relationships between ecotourism and economy with a view to understanding how the benefits, if any, are utilized within the communities.

    La Academia Nacional de Medicina rinde homenaje hoy a un español universal, don Gregorio Marañón y Posadillo (1887-1960 en el primer centenario de su nacimiento. Se asocia a la admiración y al orgullo que este hombre despierta por su inteligencia, su sabiduría y su obra entre sus gentes de España, con el entrañable afecto que su nombre evoca entre nosotros los iberoamericanos que también, a nuestra manera, lo sentimos nuestro.

    Médico, historiador, escritor, humanista, sociólogo y maestro, su espíritu se ensoñoreó por los campos abiertos del saber, descollando con méritos señeros en cada una de estas disciplinas. Y si en el presente siglo su par en la medicina podría ser don Santiago Ramón y Cajal, en las letras don José Ortega y Gassety en las humanidades don Miguel de Unamuno, por su bucear en las aguas profundas y lustrales de la historia su nombre es parangonable con el de españoles eternos con los que equiparó su vida: un Séneca, por su austero interrogar al destino y por el doloroso regustar del destierro (“carere patria intolerabili est”. Un san Isidoro de Sevilla, por su ecumenismo. Un Garcilaso de la Vega, por su poético enamoramiento de Toledo. Un Maimónides, por las enseñanzas de su saber médico y por los discípulos dejados en las más diversas latitudes unido a su excepcional amplitud de criterio -rara flor en la patria de Ignacio de Loyolay de don Felipe 11-; ausencia de ese dogmatismo y fanatismo que el mismo “espejo de los caballeros” hubo de sublimar en las brumas de su locura para ser el arquetipo de lo español y de España. Y un Miguel Servet, en fin, por sus paralelas intuiciones científicas, las de éste en la circulación de la sangre pulmonar, las de don Gregario en la endocrinología, las hormonas y las muy sutiles investigaciones del hasta hace poco coto vedado de la sexología y los estados intersexuales.

    Full Text Available The aim of this article is to project the analysis made on the Trastámara´s Castile to the concrete example of the Military Order of Calatrava, one of the most important institutions of Castile in the Middle Ages which, up to now, has not still been studied from this point of view. In order to carry on our research, we have taken advantage both chronicles and literary sources and archivistic records. Therefore, the article analyzes the dominion acquired by the most renowned Calatrava's lineages (Padilla, Guzmán, Girón in the Trastámara's Castile, using the Order resources by means of the control of his highests hierarchs. This power was evidenced through a peculiar behaviour and it was exhibited by devices, iconographic figures and some masterpieces. Shortly, the Calatrava's nobility behaved similarly to the laic one, despite his belonging to a religious institution.

    El objetivo de este artículo es proyectar el análisis en la nobleza de la Castilla Trastámara al ejemplo concreto de la Orden militar de Calatrava, una de las instituciones más importantes de la Castilla medieval y que hasta el momento no había sido estudiada desde esta perspectiva. Para nuestra investigación hemos utilizado fuentes cronísticas y literarias combinadas con documentación archivística. El artículo analiza el poder adquirido por los principales linajes calatravos (Padilla, Guzmán y Girón en la Castilla Trastámara, utilizando para ello los recursos de la Orden de Calatrava mediante el control de sus más altas jerarquías. Este poder se concretó en un determinado comportamiento y se exhibió por medio de símbolos, singulares representaciones iconográficas y ciertas obras artísticas. En definitiva, la nobleza calatrava se comportó de manera muy similar a la laica, a pesar de los condicionantes propios de la pertenencia a una institución religiosa.

    Full Text Available Abstract Traditional plant use is of tremendous importance in many societies, including most rural African communities. This knowledge is however, rapidly dwindling due to changes towards a more Western lifestyle, and the influence of modern tourism. In case of the Sekenani Maasai, the recent change from a nomadic to a more sedentary lifestyle has not, thus far lead to a dramatic loss of traditional plant knowledge, when compared to other Maasai communities. However, in Sekenani, plants are used much less frequently for manufacturing tools, and for veterinary purposes, than in more remote areas. While the knowledge is still present, overgrazing and over-exploitation of plant resources have already led to a decline of the plant material available. This paper examines the plant use of the Maasai in the Sekenani Valley, North of the Masaai Mara National Reserve. The Maasai pastoralists of Kenya and Tanzania use a large part of the plants in their environment for many uses in daily life. The plant use and knowledge of the Sekenani Maasai is of particular interest, as their clan, the "Il-Purko", was moved from Central Kenya to this region by the British Colonial Administration in 1904. The results of this study indicate that despite their relocation 100 years ago, the local population has an extensive knowledge of the plants in their surroundings, and they ascribe uses to a large percentage of the plants found. One-hundred-fifty-five plant species were collected, identified and their Maa names and traditional uses recorded. Although fifty-one species were reported as of "no use", only eighteen of these had no Maasai name. Thirty-three were recognized by a distinctive Maa name. Thirty-nine species had a medicinal use, and 30 species served as fodder for livestock. Six species could not be identified. Of these plants five were addressed by the Maasai with distinct names. This exemplifies the Sekenani Maasai's in-depth knowledge of the plant resources

    Full Text Available We investigate the mass balance of the Cenozoic Andes-Amazon source to sink system using rock uplift proxies and solid sedimentation of the Marañón Basin in Peru. The evolution of sedimentation rates is calibrated with regional structural restored cross-section. The quantification of eroded sediments from reliefs to sedimentary basin is achieved with ×10 Myr resolution and compared to present day proxies from the HYBAM (HYdrologie et Biogéochimie du Bassin Amazonien Critical Zone Observatory. Erosion of the early Andean landforms started during the Upper Mesozoic period, but sediment rates significantly increase during the Neogene. This is in agreement with the calibrated increase of rock uplift in the Andean orogenic belt.

  19. Land use and climate change impacts on the hydrology of the upper Mara River Basin, Kenya: results of a modeling study to support better resource management

    2011-07-01

    Full Text Available Some of the most valued natural and cultural landscapes on Earth lie in river basins that are poorly gauged and have incomplete historical climate and runoff records. The Mara River Basin of East Africa is such a basin. It hosts the internationally renowned Mara-Serengeti landscape as well as a rich mixture of indigenous cultures. The Mara River is the sole source of surface water to the landscape during the dry season and periods of drought. During recent years, the flow of the Mara River has become increasingly erratic, especially in the upper reaches, and resource managers are hampered by a lack of understanding of the relative influence of different sources of flow alteration. Uncertainties about the impacts of future climate change compound the challenges. We applied the Soil Water Assessment Tool (SWAT to investigate the response of the headwater hydrology of the Mara River to scenarios of continued land use change and projected climate change. Under the data-scarce conditions of the basin, model performance was improved using satellite-based estimated rainfall data, which may also improve the usefulness of runoff models in other parts of East Africa. The results of the analysis indicate that any further conversion of forests to agriculture and grassland in the basin headwaters is likely to reduce dry season flows and increase peak flows, leading to greater water scarcity at critical times of the year and exacerbating erosion on hillslopes. Most climate change projections for the region call for modest and seasonally variable increases in precipitation (5–10 % accompanied by increases in temperature (2.5–3.5 °C. Simulated runoff responses to climate change scenarios were non-linear and suggest the basin is highly vulnerable under low (−3 % and high (+25 % extremes of projected precipitation changes, but under median projections (+7 % there is little impact on annual water yields or mean discharge. Modest increases in precipitation

    Directory of Open Access Journals (Sweden)

    Sérgio Leandro Alves da Silva

    Full Text Available Este trabalho apresenta uma proposta para a automatização do processo de calibração de câmaras usando a localização e medição de pontos em alvos codificados, com precisão subpixel, o que contribui para minimizar os erros de localização, independente da orientação da câmara e da escala da imagem. Para alcançar este objetivo foram analisados os alvos codificados mais relevantes na literatura, sendo escolhido o padrão ARUCO, devido à sua flexibilidade, capacidade para representar até 1.024 alvos diferentes e disponibilidade de código fonte, implementado com a biblioteca OpenCV, que garante simplicidade de implementação e alta confiabilidade. Após a geração dos alvos com o padrão ARUCO, foram criados os painéis usados para a aquisição das imagens empregadas na calibração da câmara. O programa desenvolvido foi usado para localizar os alvos nas imagens e extrair automaticamente as coordenadas dos quatro cantos, com precisão subpixel. Os experimentos realizados mostraram que a maioria dos alvos foi identificada corretamente. Os resultados do experimento com a calibração de uma câmara de baixo custo mostraram que o processo funciona e que a precisão das medidas dos cantos atinge o nível subpixel.

    Alice F. Hill

    2018-04-01

    Full Text Available We use remote sensing to enhance the interpretation of the first baseline dataset of hydrologic, isotopic and hydrochemical variables spanning 620 km of the upper Marañón River, in Andean Peru, from the steep alpine canyons to the lower lying jungle. Remote, data-scarce river systems are under increased hydropower development pressure to meet rising energy demands. The upstream-downstream river continuum, which serves as a conduit for resource exchange across ecosystems, is at risk, potentially endangering the people, environments, and economies that rely on river resources. The Marañón River, one of the final free-flowing headwater connections between the Andes and the Amazon, is the subject of myriad large-scale hydropower proposals. Due to challenging access, environmental data are scarce in the upper Marañón, limiting our ability to do system-wide river basin planning. We capture key processes and transitions in the context of hydropower development. Two hydrologic regimes control the Marañón dry-season flow: in the higher-elevation upper reaches, a substantial baseflow is fed by groundwater recharged from wet season rains, in contrast to the lower reaches where the mainstem discharge is controlled by rain-fed tributaries that receive rain from lowland Amazon moisture systems. Sustainability of the upper corridor’s dry-season baseflow appears to be more highly connected to the massive natural storage capacity of extensive wetlands in the puna (alpine grasslands than with cryospheric water inputs. The extent and conservation of puna ecosystems and glacier reservoirs may be interdependent, bringing to bear important conservation questions in the context of changing climate and land use in the region. More generally, this case study demonstrates an efficient combined remote sensing and field observation approach to address data scarcity across regional scales in mountain basins facing imminent rapid change.

    The aim of this study was to assess the impact of mist-chilling on high-grade strawberry post-harvest quality (Cultivars ''Gariguette'' and ''Mara des Bois''). Strawberries were chilled at 2 C using three processes: air blast chilling at 0.3 m s{sup -1} or 1 m s{sup -1} and mist-chilling at 1 m s{sup -1}. After chilling, fruits were submitted to different distribution chains characterised by different handling conditions and storage temperatures (2 C or 7 C) and by a 12 h retailing step at 20 C. Strawberry quality was assessed by measuring 7 parameters: weight loss, commercial loss, firmness, sugar content, acidity, colour and sensory quality. Compared to air-chilling, mist-chilling did not reduce chilling time but it reduced weight loss by 20-40%. Mist-chilling had no detrimental effect on commercial loss defined as the percentage of fruit more than 1/3 of surface affected. It did not induce any major changes on strawberry quality. Temperature fluctuations undergone during cold storage and retailing had a detrimental effect on weight loss. The beneficial effect of packaging on weight loss was confirmed. (author)

    Full Text Available Este artigo discute os desafios à representação política de mulheres na Câmara dos Deputados. Argumento que à demanda pela eleição de mais mulheres deve ser agregada a discussão sobre as regras e procedimentos que regulam sua atuação, uma vez que essas podem limitá-la ou torná-la mais efetiva do ponto de vista da representação de mulheres. Avaliando a distribuição de recursos legislativos (vagas em comissões legislativas e presidências de comissões e da Mesa Diretora entre legisladoras e legisladores, pode-se constatar que essa ocorre de forma desigual. Apesar disso, destaca-se positivamente a criação da Secretaria da Mulher, instância que pode potencializar a atuação das legisladoras, mitigando os efeitos decorrentes dessas constituírem uma “pequena minoria”. Por fim, argumento que o desafio de eleger mais mulheres deve se articular à necessidade de garantir que às mulheres já eleitas sejam assegurados recursos que potencializem mudanças que garantam maior presença de mulheres nos espaços de poder e decisão.

    The sanitary control of threatened wild animals is of pivotal interest for their conservation. This task, however, is highly complex in wildlife/livestock systems. In this paper we report findings from a 2-year cross-sectional study of the epidemiology and attempted control of a Sarcoptes mite infestation in the threatened cheetah population in Masai Mara (Kenya), and discuss its interaction with sympatric wild (lion, wildebeest and Thomson's gazelle) and domestic (dog, cattle and sheep) animals. Sarcoptes scabiei was isolated from cheetahs, Thomson's gazelles, wildebeests, lions, cattle, goats and dogs; Psoroptes ovis, on the other hand, was only isolated from sheep. The prevalence study revealed 12·77% infection rates in cheetahs, 4·7% in dogs, 0·8% in Thomson's gazelles, 0·8% in sheep, 0·09% in cattle, and 0·09% in goats, while it opportunistically affected lions and wildebeest. Our study revealed that prevalence of Sarcoptes mite in cheetah population was not associated with the studied geographical blocks, animal sex or the presence of affected domestic animals. Cheetah infection with S. scabiei was associated with the climatic conditions (dry more than wet season) and the balancing between the total number of Thomson's gazelles and the prevalence of infected individuals. Apparently the high prevalence of mangy gazelles has a negative effect on cheetah; this negative effect was reduced when the number of healthy gazelles was increased. Treatment with injectable ivermectin of the clinically affected wild and domestic animals during the first year of this study was associated with much lower incidence of sarcoptic mange during the second year.

    Full Text Available This article provides a preliminary list of alien plant species in the Serengeti-Mara ecosystem in East Africa. The list is based on broad-scale roadside surveys in the area and is supplemented by more detailed surveys of tourist facilities in the Masai-Mara National Reserve and adjoining conservancies. We encountered 245 alien plant species; significantly more than previous studies, of which 62 (25% were considered to have established self-perpetuating populations in areas away from human habitation. These included species which had either been intentionally or accidentally introduced. Of the 245 alien plants, 212 (including four species considered to be native to the region were intentionally introduced into gardens in the National Reserve and 51 (24% had established naturalised populations within the boundaries of these tourism facilities. Of the 51 naturalised species, 23 (11% of the 212 alien species were recorded as being invasive within the ecosystem, outside of lodges and away from other human habitation. Currently, the Serengeti-Mara ecosystem is relatively free of widespread and abundant invasive alien plants, with a few exceptions, but there are extensive populations outside of the ecosystem, particularly to the west, from where they could spread. We address the potential impacts of six species that we consider to pose the highest risks (Parthenium hysterophorus, Opuntia stricta, Tithonia diversifolia, Lantana camara, Chromolaena odorata and Prosopis juliflora. Although invasive alien plants pose substantial threats to the integrity of the ecosystem, this has not yet been widely recognised. We predict that in the absence of efforts to contain, or reverse the spread of invasive alien plants, the condition of rangelands will deteriorate, with severe negative impacts on migrating large mammals, especially wildebeest, zebra and gazelles. This will, in turn, have a substantial negative impact on tourism, which is a major economic activity

Dudley-Evans & St. John (1998, p.37 maintain that “their English tuition up to the tertiary level will generally have been in the area of General English, and is unlikely to have included specific preparation for study at university level…” Barker (2000, p.8, in his study on first year students’ perception of writing difficulties, found that the students “come to realise during first semester that they are not adequately prepared for the writing demands required at university”. Pecorari (as cited in Phakiti & Li, 2011 found that Asian ESL students had problems in academic writing; “the students begin their aca-demic writing from ‘copying’ which implies a lack of training in academic writing and arouses accusations of plagiarism in their writing” (p.232.

    Full Text Available The article aims to analyze the trajectory of Manuel Arruda da Câmara (1752-1810, a reference in Botany and Medicine in the late 18th century, highlighting his vision of Brazilian Nature. The most representative concepts of the Enlightenment, like the belief in the power of reason, the knowledge of nature, the ideas of happiness and progress were also evident in colonial Brazil. Natural History and its branches attracted the interest of scholars such as Manuel Arruda da Câmara, highlighting important studies about Botany and its relationship with other areas of knowledge like Medicine, Agriculture, and Chemistry. The impact of theories of inferiority and immaturity conferred to American Nature in the second half of the 18th century by European thinkers such as Buffon and De Pauw, was also critical in formulating this knowledge. These theories predicated upon the assertion of a close organic connection between living creatures and nature, in a deterministic way. Learned men sought to respond these statements making studies that refuted the negative characterization of American continent. Thus it was important emphasize the potential and virtues of local nature.

    Full Text Available Tropopause folds are one of the mechanisms of stratosphere–troposphere exchange, which can bring ozone rich stratospheric air to low altitudes in the extra-tropical regions. They have been widely studied at northern mid- or high latitudes, but so far almost no studies have been made at mid- or high southern latitudes. The Moveable Atmospheric Radar for Antarctica (MARA, a 54.5 MHz wind-profiler radar, has operated at the Swedish summer station Wasa, Antarctica (73° S, 13.5° W during austral summer seasons from 2007 to 2011 and has observed on several occasions signatures similar to those caused by tropopause folds at comparable Arctic latitudes. Here a case study is presented of one of these events when an ozonesonde successfully sampled the fold. Analysis from European Center for Medium Range Weather Forecasting (ECMWF is used to study the circumstances surrounding the event, and as boundary conditions for a mesoscale simulation using the Weather Research and Forecasting (WRF model. The fold is well resolved by the WRF simulation, and occurs on the poleward side of the polar jet stream. However, MARA resolves fine-scale layering associated with the fold better than the WRF simulation.

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

Después de 6 meses, los animales se perfundieron con una mezcla de glutaraldehído y paraformaldehído, y se evaluó el aspecto microscópico de los nervios regenerados en dos niveles dentro de la cámara (3 mm y nivel medio y 5 mm distal a ésta. Se contó el número de fibras mielínicas presentes en cada nivel y tratamiento, y se realizó una comparación entre ellos. Se encontró una importante desorganización del endoneurio a nivel medio de la cámara. Distalmente, los conteos de fibras mielínicas fueron muy bajos. No se observaron diferencias significativas entre los grupos con mallas de 10 y 60 pm. En conclusión, la presencia de poros de 10 o 60 pm no impide la entrada masiva de fibroblastos a la cámara, llevando a una marcada desorganización del nervio regenerado.

    Full Text Available Reproduction is described for four phyllodactylid geckos, Phyllopezus maranjonensis, Phyllodactylus delsolari, P. thompsoni and P. reissii from the upper Marañon Valley, Peru. Observations were made between March and May 2010 and voucher specimens, already housed in the Zoologisches Forschungsmuseum Alexander Koenig (ZFMK, were X-rayed to check for gravid females. Gravid female P. maranjonensis, P. delsolari and P. reissii contain two eggs, whereas P. thompsoni produces a single egg that is deposited in leaf litter or crevices of stone walls. It is likely that females of all of these species produce multiple clutches in one year; the reproductive period seems to be extended in at least two species. Furthermore, measurements of numerous specimens of all four species are presented herein, revealing that Phyllopezus maranjonensis is the largest species of New World geckos.

    Directory of Open Access Journals (Sweden)

    Paula Debiasi

    Full Text Available O conhecimento dos parâmetros que definem a geometria interna de uma câmara é fundamental em trabalhos fotogramétricos. Porém, é de suma importância que o processo de calibração da câmara seja realizado em condições técnicas e ambientais similares ao aerolevantamento. No georreferenciamento direto os parâmetros de orientação exterior da câmara podem ser determinados com base nas observações GPS e INS. A utilização destes parâmetros, em um processo de calibração com parâmetros adicionais, possibilita a atenuação de correlações entre parâmetros de orientação interior e exterior. Este artigo investiga o uso dos parâmetros de posição da câmara e diferentes configurações de pontos de apoio altimétrico na calibração em serviço de uma câmara digital Kodak DSC Pro SLR/c. O impacto do uso de faixas cruzadas na calibração em serviço foi avaliado pela análise da correlação estatística entre os parâmetros de orientação interior e exterior. Finalmente, as exatidões planialtimétricas obtidas nos experimentos de calibração em serviço, com diferentes configurações de pontos de apoio altimétrico e faixas de voo, foram comparadas através da análise das discrepâncias de pontos de verificação.

    Full Text Available O objetivo desta pesquisa foi avaliar o efeito sobre a densidade de base + véu de filmes radiográficos, decorrente do uso da luz filtrada pelo polímero acrílico utilizado nas câmaras portáteis para processamento radiográfico. Filmes Kodak Ultra-speed e Ektaspeed Plus foram colocados no interior de uma câmara desse tipo e submetidos durante cinco minutos às condições de iluminação natural e artificial em que elas são rotineiramente utilizadas. Depois disso, os filmes foram processados pelo método temperatura-tempo em câmara escura convencional, juntamente com filmes dos mesmos grupos de sensibilidade que serviram como controle. Os valores densitométricos obtidos das amostras dos filmes foram analisados pelo teste de Mann-Whitney que indicou ao nível de 1% de significância, que os filmes submetidos às condições da câmara portátil apresentaram densidades de base + véu maiores em relação aos grupos controle. Os resultados mostraram que o filme Ektaspeed Plus apresentou valores maiores de densidade de base + véu em comparação com o filme Ultra-speed e que, embora o acrílico filtre a luz de forma similar ao filtro Kodak GBX 2, a maior intensidade de luz no interior da câmara escura portátil ocasionou o aumento na densidade de base + véu.

    Full Text Available Abstract Background Recently, there have been attempts to understand the molecular epidemiology of Sarcoptes scabiei, to evaluate the gene flow between isolates of S. scabiei from different hosts and geographic regions. However, to our knowledge, a molecular study has not been carried out to assess the molecular diversity and gene flow of Sarcoptes mite in a predator/prey ecosystem. Results Our study revealed an absence of gene flow between the two herbivore (Thomson's gazelle and wildebeest- and between the two carnivore (lion and cheetah-derived Sarcoptes populations from Masai Mara (Kenya, which is in discrepancy with the host-taxon law described for wild animals in Europe. Lion- and wildebeest-derived Sarcoptes mite populations were similar yet different from the Thomson's gazelle-derived Sarcoptes population. This could be attributed to Sarcoptes cross-infestation from wildebeest ("favourite prey" of the lion, but not from Thomson's gazelle. The cheetah-derived Sarcoptes population had different subpopulations: one is cheetah-private, one similar to the wildebeest- and lion-derived Sarcoptes populations, and another similar to the Thomson's gazelle-derived Sarcoptes mite population, where both wildebeest and Thomson's gazelle are "favourite preys" for the cheetah. Conclusions In a predator/prey ecosystem, like Masai Mara in Kenya, it seems that Sarcoptes infestation in wild animals is prey-to-predator-wise, depending on the predator's "favourite prey". More studies on the lion and cheetah diet and behaviour could be of great help to clarify the addressed hypotheses. This study could have further ramification in the epidemiological studies and the monitoring protocols of the neglected Sarcoptes mite in predator/prey ecosystems.

    Full Text Available The city of Maraş has been located geographically at the intersection of East Anatolia, Southeast Anatolia and Middle Anatolia regions. The city functioned as the capital city of Gurgum Kingdom which was one of Late Hitit cities due to its location and became an important center for long years at the intersection of trade ways passing through the region. Native people mostly dealt with agriculture and ranching to keep on living. The city has benefited from the advantages of being located on a plain next to Ceyhan River. Through the years, it became a region in which plenty kinds of fruits and vegetables were harvested. At the same time the city was an important region because of native people’s arts and crafts. The city always attracted the attention of domestic as well as foreign people due to the growing rice and cotton which were really precious industrial plants. The city of Maraş which is the main topic of this article became a station of food supplies for the army during World War I because of all these features. Sometimes arguments had taken place between the native people and the army for rice and other kinds of supplies which the city had given to the army. The city’s socioeconomic visage was changed with loss of population due to epidemics of diseases as the consequence of wars and exiles from the neighboring regions during the wars. The wartorn city was destroyed and put into fire due to many attacks during the period of National Struggle. That’s why the city needed a long time period to repair itself.

Entretanto, como as câmaras são construídas? Para responder essa questão, nós hipotetizamos que o jardim de fungo atua como um molde para a construção das câmaras. Assim, foram utilizadas 20 colônias de 6 meses de idade, divididas em quatro séries experimentais: padrão (quantidade normal de jardim de fungo; metade de jardim de fungo; dobro de jardim de fungo e sem jardim de fungo (Testemunha. As variáveis estudadas foram: parâmetros morfológicos das estruturas (túneis e câmara formada; fluxo das atividades das operárias; volume de solo escavado. Como se esperava, o jardim de fungo atua como um molde para a construção das câmaras em formigas cortadeiras. Os resultados foram: o tratamento sem jardim de fungo não apresentou nenhuma câmara, apenas túneis, em contraposição às demais séries experimentais que apresentaram no mínimo 2 câmaras, com dimensões similares; o fluxo das operárias carregando pellet de solo por minuto durante as 72 horas diferiu estatisticamente entre as séries experimentais e, finalmente, o volume do solo escavado foi resultado da taxa de escavação das operárias, diferindo estatisticamente entre as séries experimentais. Os resultados corroboram a hipótese de que o jardim de fungo atua como um molde para a construção da câmara. A ausência de uma estrutura funcional como uma câmara, quando o jardim de fungo está ausente, comprova a hipótese.Adult nests of leaf cutting ants (genus Atta and Acromyrmex are composed of thousands of underground chambers, which harbor the fungus garden, garbage and their population.

    Full Text Available This article examines three works by Gregorio Marañón, published for the first time in 1926 under the epigraph Tres ensayos sobre la vida sexual [Three essays on sexual life]. These essays had a huge impact and they were republished several times. The aim of this paper is to help situate Marañon’s medical and scientific views, as expressed in these essays, in the political, scientific and socio-cultural context of 1920s Spain. Marañón’s theory of sexual differentiation and his defence of women’s maternal mission is discussed at a time when many feminists accepted a sexualised view of the world in which women’s identity was articulated around motherhood. The analysis of these essays is framed in the contemporary historiography on sexuality and women’s history.En este artículo se examinan tres trabajos de Gregorio Marañón, publicados por primera vez en 1926 y agrupados bajo el epígrafe de Tres ensayos sobre la vida sexual. Estos ensayos tuvieron una gran resonancia y fueron objeto de numerosas ediciones. El objetivo de este trabajo es contribuir a situar las posiciones científicas y médicas, expresadas por Marañón en estos ensayos, en el contexto socio-cultural, científico y político de la España de la década de 1920. Se discute la teoría de la diferenciación sexual de Marañón y su defensa de la misión maternal de las mujeres en una época en la que muchas feministas asumieron una visión sexualizada del mundo y en la que la identidad femenina se articulaba en torno a la maternidad. El análisis de estos ensayos es enmarcado en la historiografía contemporánea sobre la historia de la sexualidad y la historia de las mujeres.

    Full Text Available The medieval Alcázar (fortress of Madrid was transformed into the residential palace of the Austrian dynasty in Spain from the reign of Charles I through that of Charles II. On Christmas Eve 1734, during the reign of the Bourbon king Philip V, the palace suffered a devastating fire, resulting in the construction of a new Royal palace, already baroque, on the same site. This research reconstructs the history – until now fragmented – of this lost medieval castle, contributing new source materials concerning the successive interventions carried out on the building. Specifically, this investigation focuses on the improvements realized during the period of the Catholic Monarchs and the first works commissioned by Charles V, prior to the definitive royal bond of 1536. This document marks the beginning of a new chapter in the constructive history of the building, when the old castle was transformed definitively into a residential palace, while highlighting the symbolic value of the Sala Rica and the rooms of protocol constructed during the Trastámara period.El alcázar medieval de Madrid se convirtió en la gran residencia de los Austrias desde la llegada de Carlos I al reinado de Carlos II. En la Nochebuena de 1734, reinando ya Felipe V de Borbón, el palacio sufrió un devastador incendio, resultado del cual se inicia la construcción del nuevo Palacio Real, ya barroco, sobre su solar. En esta investigación nos ocupamos de reconstruir la historia –hasta ahora fragmentada– de ese castillo medieval, aportando nuevos datos documentales acerca de las sucesivas intervenciones sufridas en el edificio. Nos centramos de forma especial en las obras realizadas en el período de los Reyes Católicos y en las primeras encargadas por Carlos V, antes de la definitiva real cédula de 1536 que marca el comienzo de un nuevo capítulo en la historia constructiva del edificio al transformarse de manera definitiva el viejo castillo en un palacio residencial

    Fold-thrust belts along convergent margins around the world host major ore deposits. The origin of such ore deposits is commonly episodic and so are the temporal and spatial variations in deformation styles in these fold-thrust belts. Here we focus on the Marañón Fold-Thrust Belt (MFTB) of the Peruvian Andes, and demonstrate a link between the spatio-temporal distribution of ore deposits and thick-skinned tectonics. We present low-temperature thermochronology results from the MFTB that document the uplift/exhumation history and timing of thick-skinned tectonics and vergence reversal. Our results suggest that the thermal history of the MFTB involved two discrete intervals of opposed-vergence, large-scale crustal deformation since the Late Cretaceous. An early interval, at 80-20 Ma, was associated with folding and east-vergent thin-skinned tectonics, and was followed by west-vergent thick-skinned deformation at 20-0 Ma. Furthermore, our findings suggest that thick-skinned contraction was coincident with increased focusing of mineralising fluids and ore deposition in the MFTB during the early Miocene, and in the mid-Miocene both mineralisation and deformation were enhanced by subduction of the Nazca Ridge underneath the South American Plate.

Para superar estos limitantes, en esta investigación se acoplaron el uso de cámaras digitales (de un teléfono celular, una cámara web o una cámara digital semiprofesional y un software libre para análisis de imágenes (ImageJ, con el fin de determinar el área foliar en forma simple, precisa y a bajo costo. Para estimar la sensibilidad de este sistema, en la primera prueba se compararon las áreas generadas por un medidor de área foliar y por las fotografías tomadas con tres tipos de cámara digital, sobre cuadrados de papel verde de áreas conocidas. En la segunda prueba se correlacionaron los valores de área foliar obtenidos con el medidor de área foliar y los obtenidos a partir del análisis de fotografías de hojas tomadas con las tres cámaras digitales, en cinco especies vegetales, que variaban en morfología y color de hojas. Los resultados indicaron coeficientes de correlación mayores a 0,99 entre los valores de área real de las piezas de papel y los valores de área estimados por el medidor de área foliar o de las fotografías. En la segunda prueba, las mediciones de area foliar obtenidas con el medidor de area foliar y con las cámaras digitales presentaron coeficientes de correlación muy altos (r=1. Los coeficientes de líneas de regresión entre las áreas del medidor de área foliar y de las fotografías del teléfono celular estuvieron entre 0,98 y 1,02, indicando una desviación máxima de 2% comparado con las mediciones del medidor de área foliar. Estos resultados sugieren una gama amplia de posibilidades para este sistema como herramienta para la investigación agrícola y biológica, debido a la disponibilidad de estos equipos que son de bajo costo, fáciles de usar y portátiles.Abstract.

    Full Text Available Resumen: La percepción de profundidad se hace imprescindible en muchas tareas de manipulación, control visual y navegación de robots. Las cámaras de tiempo de vuelo (ToF: Time of Flight generan imágenes de rango que proporcionan medidas de profundidad en tiempo real. No obstante, el parámetro distancia que calculan estas cámaras es fuertemente dependiente del tiempo de integración que se configura en el sensor y de la frecuencia de modulación empleada por el sistema de iluminación que integran. En este artículo, se presenta una metodología para el ajuste adaptativo del tiempo de integración y un análisis experimental del comportamiento de una cámara ToF cuando se modifica la frecuencia de modulación. Este método ha sido probado con éxito en algoritmos de control visual con arquitectura ‘eye-in-hand’ donde el sistema sensorial está compuesto por una cámara ToF. Además, la misma metodología puede ser aplicada en otros escenarios de trabajo. Abstract: The depth perception is essential in many manipulation tasks, visual inspection and robot navigation. The cameras of Time of Flight (TOF generate range images which provide depth measurements in real time. However, the distance parameter computed from these cameras is strongly dependent on the integration time set for the sensor and the frequency of modulation used by the integrated lighting system. In this paper, a methodology for automatic setting of integration time and an experimental analysis of ToF camera behavior adjusting its modulation frequency is presented. This method has been successfully tested on visual servoing algorithms with architecture ‘eye-in-hand’ in which the sensory system consists of a ToF camera, in addition this methodology can be applied to other workspaces and scenarios.

    Full Text Available The main advantages of single-chamber solid oxide fuel cells (SOFCs respect to dual-chamber SOFCs, are to simplify the device design and to operate in mixtures of hydrocarbon (methane, propane… and air, with no separation between fuel and oxidant. However, this design requires the use of selective electrodes for the fuel oxidation and the oxidant reduction. In this work, electrolyte-supported SOFCs were fabricated using gadolinia doped ceria (GDC as the electrolyte, Ni + GDC as the anode and LSC(La0.5Sr0.5CoO3-δ-GDC-Ag2O as the cathode. The electrical properties of the cell were determined in mixtures of methane + air and propane + air. The influence of temperature, gas composition and total flow rate on the fuel cell performance was investigated. As a result, the power density was strongly increased with increasing temperature, total flow rate and hydrocarbon composition. Under optimized gas compositions and total flow conditions, power densities of 70 and 320 mW/cm2 operating on propane at a temperature of 600ºC and methane (795ºC were obtained, respectively.

    La principal ventaja de las pilas de combustible de óxido sólido (SOFCs de una sola cámara, frente a las bicamerales convencionales, es que permiten simplificar el diseño del dispositivo y operar con mezclas de hidrocarburos (metano, propano... y aire, sin necesidad de separar ambos gases, por medio del uso de electrodos selectivos a la oxidación del combustible y reducción del oxidante.

    The exploitation of mollusks by the first anatomically modern humans is a central question for archaeologists. This paper focuses on level 8 (dated around ∼ 100 ka BP) of El Harhoura 2 Cave, located along the coastline in the Rabat-Témara region (Morocco). The large quantity of Patella sp. shells found in this level highlights questions regarding their origin and preservation. This study presents an estimation of the preservation status of these shells. We focus here on the diagenetic evolution of both the microstructural patterns and organic components of crossed-foliated shell layers, in order to assess the viability of further investigations based on shell layer minor elements, isotopic or biochemical compositions. The results show that the shells seem to be well conserved, with microstructural patterns preserved down to sub-micrometric scales, and that some organic components are still present in situ. But faint taphonomic degradations affecting both mineral and organic components are nonetheless evidenced, such as the disappearance of organic envelopes surrounding crossed-foliated lamellae, combined with a partial recrystallization of the lamellae. Our results provide a solid case-study of the early stages of the diagenetic evolution of crossed-foliated shell layers. Moreover, they highlight the fact that extreme caution must be taken before using fossil shells for palaeoenvironmental or geochronological reconstructions. Without thorough investigation, the alteration patterns illustrated here would easily have gone unnoticed. However, these degradations are liable to bias any proxy based on the elemental, isotopic or biochemical composition of the shells. This study also provides significant data concerning human subsistence behavior: the presence of notches and the good preservation state of limpet shells (no dissolution/recrystallization, no bioerosion and no abrasion/fragmentation aspects) would attest that limpets were gathered alive with tools by

    Full Text Available This article presents the first half of a much more extensive investigation over Mara Salvatrucha’s social and territorial control in colonia San José del Pino and theSan Rafael community, both from the Santa Tecla municipality. In a case study conducted within the framework of a Master’s Degree in Latin American Studies at the University of Amsterdam, the effects of preventive public security policies in the area were mapped, with emphasis on the strategy known as “Santa Tecla, a Municipality free of Violence” (MLV. The article takes a closer look at the effects of the peace process which began in 2012 with the implementation of the community policing philosophy and the MLV strategy over the social fabric and local sustainability in the above mentioned communities. It also evaluates the recovery of local governance after decades of a lack of Government presence in the area. As a result of the new public security policy, crime rates have decrease, fear has decrease, local sustainability has improved and both values and social networks have been reestablished. However, it is necessary to create a public security police able to withstand on the medium and long term all demands and needs of the sector regardless who is governing the municipality; this effort cannot stop if the ultimate goal is achieving the best results.Revista Policía y Seguridad Pública 5(1 2015: 179-246

    Full Text Available Several studies have been conducted in recent years to elucidate the structure, function and significance of AcrB, MarA, SoxS and RamA in Salmonella enterica. In this study, the relative quantification of acrB, soxS, marA and ramA genes expression was evaluated in 14 strains of S. enterica, with or without accompanying mutations in the quinolone resistance-determining regions of the gyrA gene, that were exposed to ciprofloxacin during the exponential growth phase. The presence of ciprofloxacin during the log phase of bacterial growth activated the genes marA, soxS, ramA and acrB in all S. enterica strains analyzed in this study. The highest expression levels for acrB were observed in strains with gyrA mutation, and marA showed the highest expression in the strains without mutation. Considering only the strains with ciprofloxacin minimum inhibitory concentration values 0.125 [1]g/mL (low susceptibility, with and without mutations in gyrA, the most expressed gene was marA. In this study, we observed that strains resistant to nalidixic acid may express genes associated with the efflux pump and the expression of the AcrAB-TolC pump genes seems to occur independently of mutations in gyrA.

    Full Text Available Four different manufactured surface-coated silver nanoparticles (AgNPs with coating of citrate, tannic acid, polyethylene glycol, and branched polyethylenimine were used in this study. The toxicity of surface-coated AgNPs was evaluated by a luminous microbial array for toxicity risk assessment (LumiMARA using multi-species of luminescent bacteria. The salt stability of four different AgNPs was measured by UV absorbance at 400 nm wavelength, and different surface-charged AgNPs in combination with bacteria were observed using scanning electron microscopy (SEM. Both branched polyethylenimine (BPEI-AgNPs and polyethylene glycol (PEG-AgNPs were shown to be stable with 2% NaCl (non-aggregation, whereas both citrate (Cit-AgNPs and tannic acid (Tan-AgNPs rapidly aggregated in 2% NaCl solution. The values of the 50% effective concentration (EC50 for BPEI-AgNPs in marine bacteria strains (1.57 to 5.19 mg/L were lower than those for the other surface-coated AgNPs (i.e., Cit-AgNPs, Tan-AgNPs, and PEG-AgNPs. It appears that the toxicity of AgNPs could be activated by the interaction of positively charged AgNPs with the negatively charged bacterial cell wall from the results of LumiMARA. LumiMARA for toxicity screening has advantageous compared to a single-species bioassay and is applicable for environmental samples as displaying ranges of assessment results.

    Full Text Available Studies of control strategies for refrigeration systems observe, among other variables, the dynamic behavior of temperature and the consumption of electrical energy. Aiming to contribute to these studies, this work presents the proposal and validation of a mathematical model for the cooling system of a cold-storage unit. The model approximates the dynamics and interdependence of the variables, to first-order systems with time delay and the summation of effects. The input variables available are the frequency of compressor activation and the thermal load imposed on the unit, and as output variables, the air temperature both at the evaporator inlet and at the centre of the chamber, as well as the electrical power consumed by the compressor. The results obtained were satisfactory, with an error of less than 0.11 ºC for the air temperature at the evaporator inlet, of less than 0.09 ºC for the temperature at the centre of the chamber, and of less than 1% for the electrical energy consumed.Os estudos de estratégias de controle para sistemas de refrigeração observam, entre outras variáveis, o comportamento dinâmico da temperatura e da energia elétrica consumida.

O modelo aproxima a dinâmica e a interdependência das variáveis a sistemas de primeira ordem com tempo de atraso e somatória de efeitos. Como variáveis de entrada tem-se a frequência de acionamento do compressor e a carga térmica imposta à câmara e como variáveis de saída as temperaturas do ar na entrada do evaporador e no centro da câmara, bem como a potência elétrica consumida pelo compressor. Os resultados obtidos foram satisfatórios, com erro menor que 0,11 ºC para a temperatura do ar na entrada do evaporador, menor que 0,09 ºC para a temperatura do ar no centro da câmara e menor que 1

    The relationship between local and global climatic variations and the origin and dispersal of Homo sapiens in Africa is complex, and North Africa may have played a major role in these events. In Morocco, very few studies are specifically dedicated to small fossil vertebrates, and neither taphonomic nor palaeoecological studies have been undertaken on these taxa, particularly in archaeological contexts. The late Pleistocene to middle Holocene succession of El Harhoura 2 cave, situated in the region of Témara, yields an exceptionally rich small vertebrate assemblage. We present the results of a first systematic, taphonomic, and palaeoecological study of the small mammals from Levels 1 to 8 of El Harhoura 2. The absence of bone sorting and polishing, as well as the presence of significant traces of digestion indicate that the small mammal bones were accumulated in the cave by predators and that no water transport occurred. Other traces observed on the surface of bones consist mainly of root marks and black traces (micro-organisms or more probably manganese) which affected the majority of the material. The percentage of fragmentation is very high in all stratigraphic levels, and the post-depositional breakage (geologic and anthropogenic phenomena) obscure the original breakage patterns of bones by predators. According to the ecology of the different species present in the levels of El Harhoura 2, and by taking into account possible biases highlighted by the taphonomic analysis, we reconstruct the palaeoenvironmental evolution in the region. For quantitative reconstructions we used two indices: the Taxonomic Habitat Index (THI) and the Gerbillinae/Murinae ratio. Late Pleistocene accumulations were characterised by a succession of humid (Levels 3, 4a, 6, and 8) and arid (Levels 2?, 5, and 7) periods, with more or less open landscapes, ending in an ultimate humid and wooded period during the middle Holocene (Level 1). We discuss particular limits of our results and

    Full Text Available Camu camu es una fruta nativa de la Amazonía, que llama la atención por el alto contenido de vitamina C (6,116 mg/ 100 g de pulpa, está en proceso de domesticación, por lo cual se está investigando un método de propagación vegetativa que permita avanzar en el proceso de mejoramiento genético. El objetivo de este trabajo fue evaluar la capacidad rizogénica de plantas matrices promisorias de camu camu "Myrciaria dubia (Kunth McVaugh" según el aumento del número de hojas, mediante la técnica de estacas herbáceas en cámaras de subirrigación. El ensayo fue conducido mediante un Diseño de Bloques Completamente al Azar (DBCA con arreglo factorial 9Ax3B, con 3 repeticiones y 15 estacas por unidad experimental. El factor A, estuvo constituido por nueve plantas matrices y el factor B: pares de hojas con 3 niveles: 1; 2 y 3 pares. El enraizamiento fue evaluado después de 90 días. Se observó que existió interacción estadística significativa para las variables: porcentaje de enraizamiento, longitud y número de raíces. Para las variables porcentaje de callo y porcentaje de mortalidad se encontró efecto de la planta matriz y pares de hojas. Los resultados muestran que el porcentaje de enraizamiento estuvo influenciado por efectos intrínsecos adherentes a la variabilidad genotípica de las plantas matrices, presentando un alto grado de dispersión, que osciló entre 91,11 % y 0,00 %, mostrando una alta variabilidad y marcada influencia de la planta matriz sobre el proceso de rizogénesis, influyendo de manera altamente significativa en el enraizamiento. Con respecto al área foliar, estacas con 2 y 3 pares de hojas, independiente de la planta matriz, presentaron mayor capacidad de enraizamiento. Con base en estos resultados se concluye que el efecto de la variabilidad genotípica y el área foliar influyen de manera altamente significativa en el proceso de rizogénesis de estacas herbáceas de camu camu.

    Full Text Available Aparentemente, la llegada de las mujeres a la dirección cinematográfica es un fenómeno joven que no se remonta más allá de mediados del siglo XX. Por el contrario, la historiografía reciente está empezando a constatar que la presencia de las mujeres tras la cámara es un hecho desde los mismos orígenes del cine, a finales del siglo XIX. Sin embargo, en la literatura sobre el tema apenas se mencionan nombres femeninos, y cuando se hace es de una forma tangencial. El presente artículo tiene por objeto mostrar algunas de las figuras más significativas junto con sus realizaciones más destacadas, contextualizándolas en su marco geográfico, temporal e incluso social. Para ello, se ha empleado la escasa bibliografía existente al respecto, compuesta sobre todo de diccionarios de directoras, catálogos de festivales de cine y literatura crítica sobre feminismo. De ello se concluye que las realizadoras han existido a lo largo de toda la Historia del Cine, especialmente en los países occidentales, donde su acceso a los medios profesionales, aunque restringido, no ha estado vedado en ningún momento. El surgimiento de directoras en otros ámbitos (Asia, África y ciertas zonas de América Latina es un hecho más reciente, pero en imparable progreso.It seems that the presence of women in the film direction is a young phenomenon which does not run beyond the second half of the 20th century. Nevertheless, recent historiography is starting to confirm that the presence of women on the other side of the camera is a fact from the very beginning of the cinema, at the end of the 19th century. However, in the literature about this matter there are hardly female names and, when they exist, it is in a marginal way. The aim of the present article is to show some of the outstanding figures together with their principal productions, within their geographical, temporary and, even, social frame. For this it has been used the scarce bibliography existing on

    Full Text Available PURPOSE: To develop a project of hyperbaric chamber that allows its safe and reliable use in veterinary and animal experimentation. METHODS: Based on the technical specifications for the construction of hyperbaric chambers for human beings, it has been developed a design of a chamber with dimensions and characteristics for the use of a midsize animal, (dog or pig, as well as a multiple chamber for the use in small animals (mice, rats, hamsters, rabbits or cats. The technical specifications allowed that the chamber could be used both for veterinary use and for use in experiments on Health Sciences. RESULTS: A chamber with the following characteristics was built: ASTM A36 steel for the manufacture of the master cylinder and rear cover; front door built in 5052 aluminum; internal diameter of 50.5 cm and 83.0 cm in length; weight 160Kg and internal area of 150cm³; internal space to accommodate 2 acrylic baskets; 150mm high, 280mm wide and 690mm in length. It was capable of supporting a maximum of hydrostatic pressure test of 3.0 to 4.0 BAR ACT and maximum working pressure of 2.0 BAR or 3.0 ACT; equipped with security devices and valves that triggers with load of 2.2 BAR or 3.2 ACT. Tests for engineering and biological use on animals showed the effectiveness of the device. CONCLUSION: The development of the project enabled the construction of a hyperbaric chamber with security features and reliability comparable to those required by the legal and technical specifications of a hyperbaric chamber human use.OBJETIVO: Desenvolver um projeto de câmara hiperbárica que permita o seu uso seguro e confiável em veterinária e em animais de experimentação de pequeno e médio porte.

    Full Text Available The soil chamber technique is most commonly used for measuring gas exchange between soil surfaces and the atmosphere, to understand regulatory processes relevant to determine the greenhouse gas (GHG emissions from soils and to improve the emissions inventory of agricultural systems. The chambers are inserted into the soil to avoid the lateral diffusion of the gases. However, soil disturbance caused by chamber insertion causes in degassing and can result in erroneous flux data from measurements made immediately following chamber insertion. Here we assess the effect of soil disturbance associated with the insertion of the chambers on nitrous oxide (N2O and methane (CH4 fluxes with and without N fertilization, from a New Zealand pasture soil. We collected gas samples from the chambers at 0, 2, 4, 24, 96 and 168 h after chambers insertion. Our results show elevated levels of N2O inside the chambers (1.7 fold those of atmospheric concentrations outside the chambers and greater fluxes within the first 4 h of installation compared to the values observed at 24 h and later; and negative CH4 flux in the same time period, but near to zero after 24 h. Our results suggest that for accurate measurement of gas fluxes, measurements should be taken after 24 h of chambers installation to avoid the degassing effect.La técnica de la cámara es la más comúnmente usada para medir el intercambio de gases entre la superficie del suelo y la atmósfera, entender los procesos regulatorios relevantes para determinar las emisiones de gases de efecto invernadero (GHG desde los suelos, y mejorar los inventarios de emisiones de sistemas agrícolas. Las cámaras se insertan en el suelo para evitar la difusión lateral de los gases. Sin embargo, la alteración en el suelo causada por la inserción de las cámaras causa pérdida de gases y puede resultar en datos de flujos erróneos desde las mediciones realizadas inmediatamente posteriores a la inserción de las cámaras

    Full Text Available Cataratas polares anteriores piramidais são opacidades cônicas que se projetam para a câmara anterior a partir da cápsula anterior do cristalino. Na grande maioria dos pacientes a opacidade permanece aderida e estável durante toda a vida. O objetivo deste trabalho é documentar uma manifestação incomum desse tipo de catarata: a deiscência espontânea das pirâmides para a câmara anterior causando descompensação endotelial e edema corneal bilateral. Relatamos o caso de uma paciente feminina, de 66 anos, branca, que apresentava edema corneal localizado inferiormente no olho direito associado à lesão nodular branco-esclerótica compatível com a pirâmide anterior da catarata polar. O olho esquerdo apresentava edema corneal difuso intenso e presença de uma catarata polar anterior com a região piramidal deslocada para a câmara anterior. Sabe-se que a pirâmide anterior pode permanecer inabsorvida na câmara anterior por longo período, pois é composta de tecido colágeno denso. Isto causa perda endotelial progressiva e edema corneal e deve ser considerada indicação de remoção cirúrgica da catarata polar anterior e de seu fragmento. Ressalta-se, também, a importância do bom senso no julgamento das cataratas polares anteriores, considerando-se tamanho da opacidade, simetria das opacidades e componente cortical associado, na tentativa de se evitar ambliopia.Pyramidal anterior polar cataracts are conical opacities that project into the anterior chamber from the anterior capsule of the lens. In the vast majority of patients the opacity remains bound and stable throughout life. We report an unusual complication of this type of cataract: spontaneous dehiscence of the pyramids to the anterior chamber causing bilateral endothelial damage and corneal edema. 66-year-old white woman presented with inferior corneal edema in the right eye and diffuse corneal edema in the left eye.

    Full Text Available Os sistemas de rastreamento de toda a cadeia produtiva de animais estão cada vez mais presentes. Assim, todas as etapas do processo produtivo podem ser monitoradas por meio de sistemas inteligentes que auxiliam com precisão na tomada de decisão, maximizando todo o sistema. O objetivo deste trabalho foi avaliar o desempenho do sistema de identificação eletrônica por radio frequência (RFID do tipo tag passivo instalado em uma câmara de preferência ambiental (CPA quanto à detecção dos movimentos de frangos de corte, e foi realizado em duas partes: 1 Detecção do alcance das antenas utilizando um robô; 2 Rastreamento do movimento de frangos de corte entre os compartimentos da CPA. Observou-se que o sinal de RFID emitido pela etiqueta pode ser lido a aproximadamente 10 cm de distância da antena, identificando uma zona de não detecção. Portanto, o sistema RFID instalado na CPA não apresentou o desempenho esperado, e esta tecnologia deve ser replanejada ou substituída.

    Full Text Available Systems of measurement were fundamental to the development of peoples, so that the most diverse oriental and western cultures developed their own tools parallel to one another, bringing man to the creation of norms and rules of universal measurement. In Brazil, the 6th-grade math books of elementary school students bring them into formal contact with the metric system and their multiples and sub-multiples, but the students are not induced to think about other forms of measuring present in their daily lives. This paper shows, through narratives of the Kanamari indigenous people of Maraã-AM, how their ancestors measured length, distances, lands and even the height of the houses. These narratives were introduced into the classroom and presented to the 6th-grade students of the Indigneous Municipal School of Kanamari in order to teach the units of measurement with an ethnomathematical approach. Beyond rescuing a small part of their culture, this activity favored a reflection on the part of teachers about their pedagogical practices, since, community leaders, indigenous teachers and non-indigenous have noted that an institutionalized education allied to indigenous knowledge favors student learning of content, allowing for the perpetuation of Kanamari culture.

Los datos han sido extraídos de una serie de encuestas analíticas realizadas en las comunidades de San Jacinto y San Jorge, ambas beneficiarias del programa en cuestión y ubicadas en la cuenca baja del río Marañón, en el departamento y provincia de Loreto, en el distrito de Nauta. Los datos cuantitativos registrados, unidos a la observación de campo, permiten analizar de manera crítica el impacto del programa sobre las infraestructuras y la cultura tradicional amazónica. Se sustenta la hipótesis de que los cambios producidos por el programa “techo digno” han sido muy significativos, consolidando la idea de que el programa ha sido inadecuado y ajeno a la realidad cultural y ecológica de la Amazonía.

    Full Text Available RESUMEN: Durante el último tercio del V milenio a. de J.C. fueron erigidos en Asturias los primeros túmulos. En realidad, aquellos montículos artificiales responden, básicamente, al recubrimiento monumental de lugares ceremoniales, sellando plataformas de arcilla, pavimentos de piedra, pozos, hogueras o los restos de estructuras de madera incendiadas, vestigios diversos del locus dramatis de una imprecisa ritualidad funeraria. En su alta antigüedad y variedad formal, ausentes las cámaras mortuorias en sentido estricto, nos hablan estos túmulos herméticos tanto de su carácter autónomo en el contexto de las arquitecturas sepulcrales neolíticas, como de la inicial expresión de madurez de las sociedades agropecuarias radicadas en el N de la Península Ibérica.ABSTRACT: The first barrows were raised in Asturias during the last third of the 5th millennium B.C. Actually, these artificial mounds basically respond to the monumental covering of ceremonial sites, sealing clay platforms, stone paving, wells, bonfires or the remains of burned wooden structures; diverse vestiges of the locus dramatis of imprecise funerary rituals. The great antiquity and formal variety of these sealed barrows, lacking in funeral chambers in the strictest sense, speak to us both of their autonomous character within the context of Neolithic burial architecture, as well as the initial expression of the maturity of the farming societies established in the North of the Iberian Peninsula.

No Brasil esta realidade ganha destaque, sobretudo nas regiões Norte e Nordeste do País e é neste contexto que a Comunidade de Sombras Grandes e Milagres, no município de Caraúbas – RN esta inserida. Até cinco anos atrás as famílias viviam numa situação de pobreza extrema, que foi alterada pela intervenção integrada de ações e políticas públicas, através do Projeto Dom Helder Câmara – PDHC/Secretaria de Desenvolvimento Territorial - SDT/Ministério do Desenvolvimento Agrário - MDA/Fundo Internacional de Desenvolvimento Agrícola - FIDA/ Fundo Global para o Meio Ambiente - GEF – ONU, que dentre tantas atividades passou a substituir o trabalho com a agricultura convencional e a produção de carvão, pela agricultura sustentável com o cultivo de hortas agroecológicas, entre outros. O presente artigo tem como objetivo apresentar uma breve descrição das mudanças ocorridas na renda das famílias a partir da produção, cultivo e comercialização de hortaliças, o que permitiu saltar de uma renda de R$ 90 reais mensais, pouco mais de 1/3 do salário mínimo em 2005, e chegar a uma renda atual (março 2012 de quase 900 reais ao mês. Caracterizando também os benefícios e a relação das famílias com o meio ambiente a luz desta atividade.

    Full Text Available Quality control of fruits to satisfy increasingly competitive food markets requires the implementation of automatic servovisual systems in fruit processing operations to cope with market challenges. A new and fast method for identifying and classifying moving fruits by processing single color images from a static camera in real time was developed and tested. Two algorithms were combined to classify and track moving fruits on image plane using representative color features. The method allows classifying the fruit by color segmentation and estimating its position on the image plane, which provides a reliable algorithm to be implemented in robotic manipulation of fruits. To evaluate the methodology an experimental real time system simulating a conveyor belt and real fruit was used. Testing of the system indicates that with natural lighting conditions and proper calibration of the system a minimum error of 2% in classification of fruits is feasible. The methodology allows for very simple implementation, and although operational results are promising, even higher accuracy may be possible if structured illumination is used.El control de calidad en frutas y hortalizas para satisfacer mercados cada vez mas exigentes, requiere la implementación de sistemas automáticos servo visuales en operaciones de de procesamiento de frutas para responder a estos desafíos de mercado.

    Full Text Available O objetivo deste trabalho foi calibrar uma câmara prática e de baixo custo, para quantificar a amônia volatilizada do solo. A calibração da câmara foi realizada pela técnica do balanço do isótopo 15N. A amônia volatilizada foi capturada por uma câmara semiaberta livre estática (SALE, confeccionada a partir de garrafa de plástico transparente de politereftalato de etileno (PET de 2 L. O interior da câmara apresentava livre circulação de ar, e possuía uma lâmina de espuma de poliuretano, com 2,5 cm de largura e 25 cm de comprimento, pendurada verticalmente, com a extremidade inferior inserida em frasco com solução ácida, que mantinha a espuma saturada. A recuperação do 15N-NH3 no coletor aumentou de forma linear com o aumento da taxa de volatilização de NH3 do solo. Os testes de campo mostraram eficiência de 57% na recuperação do N-NH3 volatilizado do solo. O intervalo de coletas das espumas pode variar de um a seis dias, sem comprometer a eficiência do sistema. Para estudos de campo, com uso do método proposto, o fator de correção de 1,74 deve ser usado para estimar a real taxa de volatilização de amônia do solo.The objective of this work was to calibrate a practical and low-cost chamber for the quantification of ammonia volatilization from soil. The chamber was calibrated using the 15N isotope balance technique. The volatilized ammonia was captured by a semi-opened free static chamber built with a 2 L ethylene polyterephthalate (PET plastic bottle. The inner side of the chamber had free-air circulation and a stripe of polyurethane foam, with 2.5 cm wide and 25 cm long, hanged vertically with the lower end inserted in a bottle containing acid solution, which kept the foam moistened. The recovery of 15N-ammonia by the chamber increased linearly with the increase in the rate of soil ammonia volatilization. Field tests showed an efficiency of 57% in the volatilized ammonia recuperation. The sampling interval of

    Full Text Available Latin American legislatures have gone largely unstudied, with the functioning of the Argentine Chamber of Deputies prior to the 1980s being an entirely unexplored subject. This paper fills that gap by examining the organization of the Chamber, with particular focus on its standing committee system from 1946 to 2001. We assess the portability of two U.S.-based theoretical approaches to legislative organization by applying them to committee assignments. An original data set of Argentine deputies was constructed and a way of measuring political power in committees was devised for this study. Despite weak democratic governments, military interventions, and changes to the electoral system, we find that ruling parties have consistently influenced the committee system, shaping its structure and securing an over-proportion of their deputies in key committee positions. These results support the applicability of the U.S. originated Cartel Theory of legislative organization to understanding and studying legislatures outside that country.Las legislaturas latinoamericanas no han recibido debida atención. Un caso emblemático es la Cámara de Diputados Argentina, cuyo funcionamiento previo a los 1980’s ha sido inexplorado. Este artículo persigue llenar ese vacío examinando la organización de su sistema de comisiones permanentes desde 1946 hasta 2001. Para ello, evaluamos la aplicabilidad de dos teorías norteamericanas sobre organización legislativa para analizar la integración de comisiones, creamos una base de datos de diputados argentinos y diseñamos una forma de medir su poder político en las comisiones. A pesar de la inestabilidad institucional y los cambios de sistema electoral, los resultados demuestran que los partidos que controlaron la Cámara influenciaron en forma sistemática el sistema de comisiones, cambiando su estructura y asegurando la sobrerrepresentación de sus diputados en cargos clave.

Este trabalho teve como objetivo monitorar a vida de prateleira de quatro formulações de doces em massa de umbu verde e maduro à temperatura de 30 °C durante 120 dias. As alterações físico-químicas e microbiológicas foram avaliadas no referido tempo. Os resultados mostraram um decréscimo na atividade de água, um aumento nos sólidos solúveis e no açúcar redutor; pH e acidez mantiveram estáveis; e uma tendência à redução no conteúdo de açúcar não redutor em ambos os doces. Os produtos foram microbiologicamente estáveis. Recomenda-se o uso de pectina ao processo de formulações de umbu maduro e goma xantana ou xarope de glicose para produção de doces de umbu verde.The umbu (Spondias tuberosa Arr.

This work aimed to monitor the shelf life of four marmalade formulations made from green and ripe umbu, which were kept at 30 °C for 120 days. The physical, chemical, and microbiological alterations were evaluated during the time specified. The results showed a decrease in water activity; an increase in the soluble solids, and a reduction in sugar; pH and acidity remained stable; and there was a tendency to lower sucrose content in both jams. The products were microbiologically stable. The use of pectin is recommended to process the formulations made from ripe umbu, and either xanthan gum or glucose syrup to produce jam from the green umbu.

    Full Text Available Objetivo: Além da agressão química devido à penetração dos géis clareadores na polpa durante o clareamento de dentes com vitalidade pulpar, outro possível fator agressor pode ser o calor gerado pela reação de oxidação exotérmica do gel clareador, que pode também ser agravada pela fotoativação. Este estudo avaliou a variação da temperatura na câmara pulpar de dentes humanos, utilizando-se três diferentes géis clareadores, com ou sem fotoativação. Metodologia: Trinta pré-molares humanos foram cortados longitudinalmente para obtenção de duas metades: vestibular e lingual. Os 60 espécimes foram divididos em 3 grupos e os agentes clareadores utilizados variaram como segue: peróxido de hidrogênio 35% (WHP, peróxido de carbamida 37% (W e peróxido de hidrogênio 38% (OX. Metade dos espécimes foi submetida ao clareamento com fotoativação e, a outra metade, sem fotoativação. A fonte de luz utilizada foi o aparelho à base de diodo emissor de luz (LED, 3-Light, Clean Line e as temperaturas foram medidas por um termômetro digital. Os dados foram analisados por análise de variância e teste de Tukey (alfa=5%. Resultados: Os resultados de temperatura foram: sem fotoativação (WHP= 0. 68b; W= 0. 40b; OX= 0. 48b; com fotoativação (WHP= 2. 35a; W= 1. 60a; OX= 1. 80a. Conclusão: A fotoativação dos géis clareadores com LED contribuiu para um maior aumento de temperatura na câmara pulpar, mas não se atingiu a temperatura crítica de 5,5oC

    Full Text Available The leaf area index (LAI of a vineyard (Vitis vinifera L. cv. Cabernet Sauvignon located in the commune of Cauquenes, Maule Region in Chile, was estimated from digital images obtained with a commercial camera using two indirect methods: Leaf Area Gap and Brightness (LAGB and -Photogrammetric Leaf Area Quantification System (PLAQS. The latter requires deleafing of the grapevine. In a normalized difference vegetation index (NDVI map, three points of vine vigor were selected: high, medium, and low for which horizontal and vertical images were obtained. Images were filtered with the Arc View GIS 3.1 program to provide only leaf images and corresponding pixel numbers. Image area and square meters per linear meter were calculated. The best models were selected from  three linear regression adjustments: i LAI of LAGB vertical images of with LAI of PLAQS, ii LAI of PLAQS horizontal images with and, iii LAI of both types of images with PLAQS. The parameters in all models were significant. Adjustment between the LAGB and PLAQS vertical images provides greater simplicity and easy calculation since it requires only a vertical image to estimate LAI. Images thus obtained can accurately estimate LAI in this type of cultivar.En un viñedo (Vitis vinifera L. cv.

Um paciente foi submetido ao 2º tempo da operação, tunelizando a veia cava inferior (VCI para a APD, com sucesso. A avaliação do fluxo da derivação cavo-pulmonar bidirecional está sendo realizada pela ecodopplercardiografia e ressonância nuclear magnética e a perfusão pulmonar mediante cintilografia radioisotópica. A indicação do 2º tempo da operação obedece à própria evolução clínica e avaliação da saturação arterial durante a cicioergometria. A derivação cavo-pulmonar bidirecional permite uma adaptação progressiva do fluxo venoso para o pulmão, diminuindo a sobrecarga de volume do ventrículo, preparando o paciente para a derivação venosa total.From March 1990 to January 1994, 17

    Full Text Available O objetivo deste trabalho é analisar o processo de construção das instituições que regeram a política de comércio exterior no Brasil durante o governo Cardoso, tendo como foco as relações entre a mudança institucional e a dinâmica político burocrática interna ao Poder Executivo, com o qual avaliamos as condições nas quais o conflito burocrático é uma variável importante no processo de mudança institucional. Dado que o comércio exterior é uma atividade ampla, optamos por analisar as reformas realizadas sobre o seu quadro de coordenação: os processos de formação e reformas da Câmara de Comércio Exterior (CAMEX. Desenvolvemos na primeira parte do trabalho um arcabouço analítico a partir de uma avaliação breve e crítica do que já foi produzido sobre a influência e as implicações da participação da burocracia no jogo político, do qual derivamos as hipóteses de pesquisa. Em seguida, analisamos o papel exercido pelo conflito interno ao Poder Executivo entre as diferentes agências envolvidas com a política comercial e como foi a ação da Presidência. Propomos, finalmente, que o conflito e a disputa entre burocracias foi um fator determinante para a instabilidade institucional e para a consolidação de um formato subótimo, que encontra dificuldades no cumprimento das funções de coordenação do comércio exterior brasileiro. A partir da proposição de um novo arcabouço teórico que concatena diferentes debates a respeito da política burocrática, derivamos a proposição central da pesquisa que reside na expectativa de como as interações entre os atores políticos e burocráticos dentro do Poder Executivo afetam os resultados dos processos decisórios sobre mudança institucional.The aim of this paper is to analyze the institutional building process of the Brazilian foreign trade policy during the Cardoso government, focusing on the relationship between institutional change and the political

    realizado todavía en Chile. Este trabajo tiene como objetivo determinar los flujos de emisiones in situ de CO2 y N2O desde un suelo derivado de cenizas volcánicas bajo diferentes prácticas de manejo agronómico determinando su variación estacional. Las muestras gaseosas fueron obtenidas desde el espacio aéreo de cámaras cerradas no-fijas en una rotación anual de cultivos bajo sistema de cero labranza en un Andisol del Sur de Chile (36° S. Dos fuentes de N (NH4+ y NO3- y fertilización amoniacal más dos dosis de encalado (0.5 y 1 Mg ha-1 fueron considerados como tratamientos. Los flujos de CO2 y N2O fueron determinados periódicamente en un período de 1 año y variables de suelo tales como temperatura, contenido de agua, y N mineral fueron registrados. Los resultados muestran que los flujos de CO2 responden a patrones de estacionalidad. No fue evidenciado un efecto cuando fue considerada la práctica de manejo del cultivo, con un máximo de 53.2 ± 8.5 kg CO2-C ha-1 d-1 en la estación húmeda de otoño, y un mínimo de 9.7 ± 2.1 kg CO2-C ha-1 d-1 para verano, estación seca de otoño e invierno. El flujo de N2O fue altamente variable en el año y no muestra influencia de tratamientos o estacionalidad, con un promedio de 2.6 ± 0.6 g N2O-N ha-1 d-1. Variaciones de N mineral del suelo no están relacionadas a los flujos de GHG como una variable sola. Los resultados indican que un Andisol bajo sistema de cero labranza en el Sur de Chile tiene un bajo potencial de emisiones de N2O, y las mayores emisiones de CO2 son producidas principalmente en estaciones húmedas (otoño húmedo y/o primavera.

    Full Text Available In Charles Baudelaire’s «Tableaux parisiens» and Le Spleen de Paris, an eye-camera that takes pictures of reality operates in a latent way. This photographic metaphor allows the poet to capture the Parisian landscape to fix it in the positive of poetry. In this article we analyze Baudelairian poetics by an interdisciplinary perspective that combines the language of literature and photography. We will use as theoretical framework Philippe Hamon’s semiological approach and Walter Benjamin Marxist theory.

    Full Text Available Umbu pulp is an important product in the economy of the northeastern region of Brazil, and its preservation can be ensured by heat treatment. A complete factorial design with 2 factors (time and temperature and 3 central points was used to verify the effect of the HTST process on the physicochemical, chemical, physical, microbiological, and sensory qualities of umbu pulps. The results showed that the heat treatments applied resulted in products without significant alterations on the physicochemical, chemical, and microbiological characteristics. With respect to color, the parameters L and a* were altered by increases in temperature indicating by darkening of color. The sensory evaluation indicated that a treatment of 88 °C for 10 seconds was the best processing condition due to the greater similarity of the resulting product to the reference sample (blanched pulp.

    Cartwright, Elizabeth; Schow, Diana

    2016-01-01

    In this article, we anthropologically explore one part of the process of Community-Based Participatory Research (CBPR): participation. Participation in CBPR is usually conceptualized as whether, and the degree to which, community members are involved in the research process. Our focus regarding participation is less on quantity and more on quality of the interaction between community members and researchers; within this context, we elaborate the concept of "bridging" as it is understood in CBPR. Using data from our ongoing "Water Project" in the Peruvian Andes, we explore how interaction, as a participative act of the research interview, creates the space for participating and imagining. Out of this interaction come data that are elaborated, contextualized, and, ultimately, from a CBPR perspective, made useful for meaningful engagement and community action. © The Author(s) 2015.

    Gregorio Maranon born and dead in Madrid (1887-1960), was a Spanish physician, scientist, historian, philosopher, humanist, and writer, considered one of the most brilliant Spanish intellectuals of the 20th century. He was also a Republican and fought the Primo de Rivera dictatorship, though later expressed his disagreement with communism. Maranon participated closely with the process of exile of Alfonso XIII. From a very early age he learned several foreign languages and was an avid reader, hence he became in contact with the intellectual circles of the time and cultivated a close friendship with Perez Galdos, Menendez-Pelayo, Ortega y Gasset, Pio Baroja, Unamuno, Lerroux among several outstanding and eminent figures of the famous Generation of 14. In Medical School he had great teachers such as Santiago Ramon y Cajal, and later he specialized in endocrinology and became professor of the specialty in the Complutense University in Madrid, moreover he founded the Institute of Medical Pathology and the Department of Experimental Endocrinology, henceforth he contributed to establish the relationship between endocrinology and psychology. At the beginning of the instauration of the Republic, Maranon became a member of the constituent assembly and the parliament, but soon became disillusioned of communism and left Spain before the initiation of the Civil War, remaining in France until 1942 when he returned to Spain to reestablish his private practice, and soon the medical teaching at the hospital which now bears his name. Late work about history, poetry was elaborated at his Toledo Cigarral de Menores.

    2012-12-01

    Full Text Available El presente trabajo es parte de una investigación sobre formas de reestratificación desde la sociedad civil. Aquí se observan las estrategias institucionales para el tratamiento del fenómeno de las pandillas transnacionales llevadas a cabo en El Salvador. Se observa cómo estas estrategias producen mayor violencia, sin presentar opciones organizativas orientadas a mejorar la vida de los jóvenes pandilleros, sin buscar crear formas sociales productivas en el sentido de asegurar a los jóvenes marginales instancias de resistencia a los influjos del sistema capitalista que los excluye. En estos términos, se propone observar las estrategias gubernamentales y sus efectos en la transformación de las pandillas hacia formas más violentas y jerarquizadas, debido a la acción criminalizante de las instituciones del gobierno. Así pues, se propone la observación de la reestratificación institucional de las pandillas, mediante la criminalización y su asimilación al crimen organizado, como elemento que ha producido una tendencia a la jerarquización, la clandestinidad y el aumento de la violencia.

    2002-01-01

    Full Text Available In this work we apply quantitative methods to recover the individual preferences of Brazilian representatives, as expressed in their nominal votes in the 49th and 50th legislatures. The method assumes both the rational choice and spatial theories of voting. Empirical analyses show that Brazilian representatives can be accurately positioned in a single ideological continuum that reflects, in part, the consensus of Brazilian politics observers: members of the Partido dos Trabalhadores (PT - Workers? Party are positioned at the extreme left and those of the Frente Liberal (PFL - Liberal Front at the opposite end. The Partido da Social Democracia Brasileira (PSDB - Party of the Brazilian Social Democracy, in turn, moved from a center-left position in the 49th legislature to the right, in the 50th. Additional dimensions contribute very little to the explanatory capacity of the model. The spatial positioning of representatives of a same party vary significantly, and the paramount quality of the statistical model used is its capacity to provide us with a spatial interpretation of this variation. The first dimension is rather stable in both legislatures. Circumstantial evidence is raised to support the hypothesis that these dimensions reflect the relationship between the Executive and the Legislative branches of government. During this period, the Presidents of the Republic were located at the extreme right of the political space.

    It is now recognized that current testing and maintenance requirements invoke too many inadvertent reactor trips and that operating staff must devote significant amount of time and effort to comply with the requirements. With this recognition, the value and the impact of the proposed changes in the allowed outage time (AOT) and surveillance test interval(STI) are evaluated for the alternating system. Because of the testing and AOT requirements, the alternating system exhibits semi-Markovian characteristics which change states in accordance with a Markov chain but take a nonexponentially distributed amount of time between changes. It is observed from the results that there is an optimal point that gives lowest core damage probability and that the optimal point depends on input parameters. With these results, we can conclude that the methodology developed in this study can be applied to the existing alternating systems to evaluate accurately the various alternatives in the technical specifications

    Full Text Available The Day Care Institutions for children are forms of organized protection for improvement of the psycho-physical, emotional and social development of children. In this period, the growth and development are in their most intensive phase when the outside influence plays an extraordinary role both in a positive and in negative a direction. Directed and well-organized protection is of a great importance. By inclusion of children with developmental disorders in the group and with special, individual treatment of each child by adequate specialized staff, their socialization and stimulus for developmental acceleration is achieved.Many years ago, by recommendation of the Advisory Institution for Development, the doctors from the Advisory Institution for small children, the public-health nurses or by the parents initiative, the kindergartens accept children with Down syndrome, children with limited and lower level backwardness, with disharmonious development, with lower level forms of cerebral paralysis and with speech disorders.Children at the earliest age of one month are resided at the Advisory Institu­­tion for Development and receive treatment until they are categorized and are ready to start school, but certain children are sent to the kindergartens at the age of 3.In the previous years, out of five children with Down syndrome treated in the Advisory Institution for Development, four were sent to the kindergarten. Now, one of these children attends the fifth grade and two attend the first grade in a regular elementary school and one attends the special school. Three children with Spastic dyplegia, four children with lower level of retardation, two with surdomutitas and four with disharmonious development are still in the kindergarten.

    Directory of Open Access Journals (Sweden)

    Marta CENDÓN FERNÁNDEZ

    2007-01-01

    Full Text Available Au cours du Moyen Âge, les évêques représentent un double pouvoir. Tout d’abord, ils occupent avec les nobles le sommet de l’échelle sociale, et, en même temps, ils exercent leur autorité — spirituelle et temporelle — au sein de l’Église. Dans le domaine artistique, leur domination trouve une première expression dans la construction de forteresses, de palais et de cathédrales, dans le mécénat dans le cadre de leur diocèse, qu’il s’agisse de mobilier, d’habits liturgiques, d’images de dévotion, de pièces d’orfèvrerie ou de livres destinés soit au culte soit à la formation du clergé. Cependant, c’est surtout à travers les chapelles funéraires que les prélats entendent affirmer et conforter leur pouvoir. Les gisants des sépulcres commandés par les évêques arborent pour cela les symboles de leur autorité : la crosse, la mitre et, parfois, certains éléments du costume épiscopal qu’ils revêtent lors de la cérémonie de consécration.A lo largo de la Edad Media, los obispos ocupan una doble posición preponderante: están en la cumbre tanto de la sociedad, junto con la nobleza laica, como de la jerarquía eclesiástica, cuyo poder se despliega sobre aspectos temporales y espirituales. En relación con el arte, esta dominación quedará patente en sus fortalezas o palacios, en la promoción de obras en sus catedrales, teniendo en cuenta el enriquecimiento de su sede con mobiliario e indumentaria litúrgica, imágenes de devoción, obras de orfebrería o libros destinados tanto al culto como a la formación. Sin embargo, la mejor expresión del poder episcopal se halla en sus capillas funerarias y de modo particular en sus conjuntos sepulcrales donde se harán representar con sus principales símbolos de poder: báculo y mitra, así como los restantes elementos de la indumentaria episcopal cuyo simbolismo queda recogido en la ceremonia de consagración.

    Full Text Available This contribution to the recent debate on political parties in Brazil focuses on party migration by members of Brazil?s Lower House from 1985 to 1998. The assumption is that shifts in party membership tell us something about the ties between parties and their members. Data reveal an apparent paradox in this regard. As the literature has made clear, although members of Brazilian political parties indeed follow the vote of their party leader in session, parties tend to display little cohesion in the Chamber, with members rarely remaining in the same party through which they were elected. The article explains the apparent paradox by showing how the rules by which everyone plays in the Lower House make loyal voting in session and party migration compatible and even fitting behaviors.

    Full Text Available Os deputados federais brasileiros têm cinco escolhas principais de carreira política: retirar-se do jogo político (aposentar-se; concorrer a um cargo legislativo estadual (ambição regressiva; concorrer à reeleição (ambição estática; e concorrer a cargos mais altos (ambição progressiva. Este artigo monta um modelo para explicar as características das escolhas dos deputados com respeito a suas decisões de carreira na eleição de 1998. Sustentamos que não é a "natureza" da ambição política que determina a escolha, mas a avaliação dos riscos e custos contidos na decisão. Usou-se um modelo de regressão logit hierárquico para estimar o impacto das distintas estratégias políticas utilizadas pelos deputados em seus mandatos e suas campanhas eleitorais. Os principais resultados sugerem que os deputados com diferentes escolhas de carreira apresentam distintas estratégias durante seus mandatos, o que influencia decisivamente suas preferências do que fazem para sobreviver politicamente.The Brazilian incumbent legislators have five major choices of political career: to withdraw from the elected political game (to retire; to run for local legislative position (regressive ambition; to run for re-election (static ambition; and to run for higher offices (progressive ambition. This paper built a model to explaining the features of incumbent legislators choices regarding their career's decisions in 1998's Brazilian election. We argue that it is not the "nature" of political ambition that determines legislators' choice, but the evaluation of the risks and costs entailed in the decision. The main findings suggest that incumbents with different career's choices present distinct strategies during their mandates, which have decisive influences on their preferences of what they do in order to survive politically.

    Full Text Available Mammalian cancer as well as the Rous chicken sarcoma has been successfully transplanted into the anterior chamber of the eyes of guinea pigs. It was of interest, therefore, to see if the infectious myxomatosis of rabbits, another representative of the infectious tumors, could be grown in the anterior chamber of the guinea pig eye, and, if growth occurred, to compare the tumor's behaviour with that of growths of the above mentioned etiology. Forty-three full-grown guinea pigs from mixed stocks were used throughout, and seventy-eight heterologous transplantation experiments were performed. The grafts measuring less than 2 mm. in diameter were cut from the subcutaneous tissue in skin lesions of rabbits with infectious myxomatosis recently killed. The transfer to the anterior chamber was performed after the usual technique. Some degree of partial survival was found in 23,8% of the grafts, in which typical myxoma cells could be demonstrated fifteen days after the transplantation. The transplant apparently does not increase in size, differing in that respect from that of the Rous chicken sarcoma, which increases in size by 2 or 3 diameters in 2 weeks (Shrigley, Greene & Duran-Reynals, 1945. The virus was still alive in 26% of the grafts 21 days after transplantation, and was able to induce a typical disease when injected to normal rabbits. No alteration in the properties of the virus after growth in the guinea pig was noticed, and this also is different from what happens with the Rous chicken sarcoma.

    Generally, ecological research has considered the aboveground and belowground components of ecosystems separately. Consequently, frameworks for integrating the two components are not well developed. Integrating the microbial components into ecosystem ecology requires different approaches from those offered by plant ecology, partly because of the scales at which microbial processes operate and partly because of measurement constraints. Studies have begun to relate microbial community structure to ecosystem function. results suggest that excluding people and livestock from the MMNR, or preventing heavier livestock from grazing around settlements, may not change the general structure of the ecosystem (soils, plant structure), but can change the numbers and diversity of wildlife, nematodes and microbes in this ecosystem in subtle ways.

Emphasis is placed on the historiographical debate of which this research is part, and the specific meaning of the term “adesão” developed in the links between municipal government, localities, and the Vintista Cortes in Lisbon, and the court in Rio de Janeiro. This research thus recovers social memory and memories of the empire, of local social, ethnic and political tensions, and ways of celebrating the “adesão” political pact that simultaneously linked the foundation of independent Brazil and constitutional monarchic rule.

    Full Text Available Academic institutions in the country are at present re-examining their business philosophy and trying to deliver quality education to remain attractive. Pressed by globalization, liberalization and accelerating competition, the education industry is facing up to these challenges by becoming more innovative in its transformation. Getting the ISO 9000 certification is quite a trendy phenomenon nowadays. But how do the academics react to this management system innovation? This paper tests a model of innovation acceptance (ISO 9000 certification that conceptualizes interest, knowledge, involvement and perceived value as independent variables and implementation strategy as the moderator. One hundred and fifty structured questionnaires were distributed to the academic staff of the Faculty of Business Management where ISO initiatives were underway. The study shows that there is a significant correlation between perceived value with interest, knowledge, acceptance of innovation and implementation. Hierarchical multiple regression analysis indicates that the implementation strategy (participative strategy enhances the relationship between interest and innovation acceptance. Interest can be cultivated, knowledge disseminated and involvement maximized through an implementation strategy that co-opts the staff from the inception of the change initiative.

    Full Text Available The recent history of Italian cinema includes several women directors who have contributed to the diversity and variety indispensable in any artistic discipline. However, these directors have received relatively little public recognition and the distribution of their films has been limited. The fact that production by women remains relatively unknown implies that there is only partial knowledge of contemporary Italian cinema. Therefore, this article attempts to highlight this lesser known part of this industry through the analysis of the main Italian women filmmakers of the last two decades, their common universe and individual peculiarities. An interview with director Costanza Quatriglio is also included as an epilogue. She sets out the keys to her work and offers a previously unpublished reflection on the current state of Italian film and the role of women directors in it.

    La historia reciente de la cinematografía italiana cuenta con numerosas mujeres que, a pesar del escaso reconocimiento y la poca difusión de sus trabajos, han contribuido a la conformación de la diversidad y la heterogeneidad imprescindibles en cualquier disciplina artística. El desconocimiento de sus producciones da lugar a un conocimiento parcial del cine italiano contemporáneo. Así pues, este estudio pretende mostrar esa parte menos prodigada del cine a través del análisis de las principales cineastas italianas de las últimas décadas, su universo común y sus particularidades individuales. A modo de epílogo, se presenta una entrevista a la directora Costanza Quatriglio que, además de revelar las claves de su obra, nos ofrece una reflexión inédita sobre el estado actual del cine italiano y el papel de la mujer en éste.

Even though it’s significant socioeconomic and environmental importance, there is a lack of studies aimed at establishing a seedlings production model of this kind of plant. The purpose of this study was to evaluate the production of seedlings Spondias tuberosa using different substrates and size of bags. The experiment was conducted in the nursery of the Plant Ecology Laboratory (LEV from the Agrarian Sciences Center (CCA of the Federal University of Paraiba (UFPB, Areia/ PB. The experimental design was a randomized block in factorial 2 x 7 and subdivided blocks containers plots and subplots substrates. It were used substrates formulated from the starting mixture of subsoil land (37.5-100%, sand (12.5-25% and tanned cattle manure (10-50%. The containers used were black polyethylene bags with a volume of 1900 cm 3 (15 x 27 cm and 5000 cm 3 (25 x 26 cm. To obtain seedlings of Spondias tuberosa seeds were sown in seed masonry until the transplant (90 days after sowing. At 78 days after transplanting the seedlings were evaluated for height, root collar diameter, relationship shoot/root collar diameter, xylopodium diameter, root length, dry weigh of shoot and root. The datas were subjected to analysis of variance and F test, measured and compared by Tukey test at 5% probability, using the software SISVAR ® . The substrates with cattle manure provided higher values for height and root length. For the seedlings production of Spondias tuberosa , is recommended substrate subsoil land (45% + sand (15% + cattle manure (40%.

    Full Text Available Willingness to Pay for Biopesticides: A Survey of Vegetables Producers in the South Coast of Togo. The actual study assessed the willingness to pay for biopesticides by vegetables producers in coastal Togo as more sustainable alternatives than chemical pesticides. Through contingent valuation, it appeared that for purchasing biopesticides, producers are willing to pay a premium of 18-20% base on the price of Decis, the chemical pesticides among the most expensive and the most used in coastal vegetable production in Togo. The Tobit model revealed that among factors affecting vegetables producers' decision making process, information and the farm size play a crucial role. Given the low level of the premium that vegetables producers are willing to pay and the current characteristics of the farm, the introduction of biopesticides within their cropping system, could lead to mitigated success in the absence of an appropriate incentive framework.

    Full Text Available Tres grandes terremotos con Mw7 ocurrieron en la costa Pacífica de Centroamérica, durante un periodo de 72 días. El 27 de agosto del 2012, ocurrió el primer terremoto (T1 en la costa Suroeste de El Salvador (Mw=7.3. El segundo terremoto (T2 golpeó 9 días después en la costa Noroeste de Costa Rica (Mw=7.6 y el tercero el 7 de noviembre del 2012 (T3, al Noroeste de Guatemala (Mw=7,4. Cuando sucedían estos sismos, la primera pregunta para los vulcanólogos fue: ¿Pueden estos terremotos disparar algún malestar volcánico?. En este artículo se analizó la actividad volcánica durante y después de esta crisis sísmica, siguiendo: a nombre del volcán con algún cambio, b tiempo que duró este volcán en mostrar el malestar, c la distancia en kilómetros entre el volcán y el epicentro y d tipo de cambios en el volcán, los cuales se dividieron en tres: 1 incremento en la actividad sísmica, 2 combinación del incremento en la actividad sísmica, temperatura y desgasificación y/o ocurrencia de erupciones freáticas, 3 grandes erupciones con caída de ceniza. A partir de esto, se encontró que trece volcanes de Centroamérica tuvieron algún tipo de malestar, de los cuales, seis volcanes tuvieron cambios tipo 1, cuatro volcanes cambios tipo 2 y tres volcanes con cambios tipo 3. Basado en lo anterior, se estableció una aparente correlación de como los terremotos tectónicos pueden provocar cambios en los volcanes y con ello se podría entender futuras crisis sísmicas y repercusiones en los sistemas volcánicos Three large earthquakes with Mw7, occurred in the Central America Pacific coast during a period of only 72 days. On 27 August 2012, the first earthquake (T1 occurred on the Southwest coast of El Salvador (Mw=7.3. The second earthquake (T2 struck 9 days after on the Northwest coast of Costa Rica (Mw= 7.6 and the third earthquake (T3, on the Northwest coast of Guatemala (Mw=7.4. When these earthquakes happened, the first question for the volcanologist was: could these earthquakes trigger some volcanic unrest? In this manuscript analyze the volcanic activity before and after this seismic crisis by recording a the name of the volcano in unrest after the earthquakes, b time lapsed in days between and the onset of the volcanic unrest, c the distance in kilometers between the volcano and the epicenters, d the type of change of the unrest of the volcano, which were divided into three: 1 increase in seismic activity, 2 combination of increased seismic activity, temperature and degassing and/or the occurrence of phreatic eruptions, 3 large eruptions with ash fall. From this, found that thirteen volcanoes of Central America were some volcanic unrest. Of those, six volcanoes showed changes of type 1, four volcanoes with changes of type 2 and three volcanoes with changes of type 3. Based on those facts, establish an apparent correlation as tectonic earthquakes can cause changes in the volcanoes and thus could understand future seismic crisis and aftermath in the volcanic systems

    Full Text Available An automatic dispenser based on a flow-injection system used to introduce sample and analytical solution into an inductively coupled plasma mass spectrometer through a spray chamber is proposed. Analytical curves were constructed after the injection of 20 to 750 µL aliquots of a multielement standard solution (20.0 µg L-1 in Li, Be, Al, V, Cr, Mn, Ni, Co, Cu, Zn, As, Se, Sr, Ag, Cd, Ba, Tl, Pb and the acquisition of the integrated transient signals. The linear concentration range could be extended to ca. five decades. The performance of the system was checked by analyzing a NIST 1643d reference material. Accuracy could be improved by the proper selection of the injected volume. Besides good precision (r.s.d. < 2%, the results obtained with the proposed procedure were closer to the certified values of the reference material than those obtained by direct aspiration or by injecting 125 µL of several analytical solutions and samples.

    Full Text Available Pre-germination treatments such as scarification and the use of growth regulators can provide the dormancy breaking in seeds and enhance the emergence and development of seedlings. The aim of this study was to determine appropriate treatments to overcome seed dormancy and enhance the initial growth of seedlings of Spondias tuberosa. We used a randomized design in factorial 2 x 4, with the following factors: seeds scarified or not scarified and then soaked in water or aqueous solutions of gibberellin, cytokinin and ethylene, with 4 replicates and 15 seeds. There was no significant interaction between scarification treatments and use of growth regulators. Mechanical scarification and soaking seeds in solutions containing umbuzeiro growth regulators does not increase the percentage of seedling emergence, however soaking in a solution of Ethrel at 100 ppm provides higher speed of emergence and root development. Tratamentos pré-germinativos, como a escarificação e o uso de reguladores de crescimento, podem proporcionar a superação de dormência em sementes e incrementar a emergência e o desenvolvimento de plântulas. O objetivo da presente pesquisa foi determinar tratamentos adequados para a superação da dormência de sementes e potencialização do crescimento inicial de plântulas de umbuzeiro. Utilizou-se o delineamento inteiramente casualizado, em fatorial 2 x 4, sendo os fatores: sementes escarificadas ou não escarificadas e, posteriormente, imersas em água ou soluções aquosas de giberelina, citocinina ou etileno, com 4 repetições de 15 sementes. Não houve interação significativa entre os tratamentos escarificação e uso de reguladores de crescimento. A escarificação mecânica e a embebição de sementes de umbuzeiro em soluções contendo reguladores de crescimento não aumenta a percentagem de emergência de plântulas, entretanto a embebição em solução de Ethrel a 100 ppm proporciona maior velocidade de emergência e desenvolvimento do sistema radicular.

    We herein describe a new colorful species of Polychrus with a conspicuous sexual dimorphism from the dry forest of the northern portion of Región de La Libertad, Peru. The new species differs from all other Polychrus species, in that this species has very small dorsal scales and thus a higher number of scales around midbody and in the middorsal line from behind the occipital scales to the level of the posterior edge of the thigh. Furthermore, we redescribe Polychrus peruvianus whose original description is short and lacks information on intraspecific variation and sexual dimorphism. Also, we add some information on intraspecific variation and ecology of Polychrus gutturosus. Finally, we synonymize Polychrus spurrelli Boulenger with Polychrus gutturosus.

    Full Text Available Low Power Mechanisation and Small-scale Vegetable Production in the Tunisian Sahel Region. Part 2: On the Field Evaluation of Performances and of Soil Preparation Costs. In this study, it was investigated to what extent low power mechanisation could be introduced in vegetable production in the Tunisian Sahel region by evaluating its performance (labour input and field efficiency by means of field experiments in which different traction equipment was used for carrying out several cultivation operations. Furthermore, costs per unit area for soil preparation in both sandy clay and clayish sand were calculated for four different power classes and for small fields. The results showed that two wheel tractors had a real labour input for scuffling between plant rows ranging from 11.3 h/ha to 18.7 h/ha. These inputs ranged from 5.5 h/ha to 6.7 h/ha for tied crops. For mowing, the two wheel tractor had labour inputs of 17.3 and 14.2 h/ha for the first and the second cut, respectively, while for potato digging, the first and the second passage of secondary tillage these values were 11.5, 14.3 and 10.4 h/ha, respectively. Superficial soil preparation by means of a four wheel tractor gave rise to values between 2.7 and 3.5 h/ha. With respect to the cost estimation for soil preparation, the lowest costs were obtained by means of the low power mechanisation. Similar conclusions were drawn for the field efficiencies for the operations investigated. In general, these efficiencies were above 70%.

    MarA47(Yp) from Yersinia pestis, showing 47% identity to Escherichia coli MarA in its N terminus, caused resistance to antibiotics and to organic solvents when expressed in both E. coli and Y. pestis. Resistance was linked to increased expression of the AcrAB multidrug efflux pump. In four of five spontaneous multidrug-resistant mutants of Y. pestis independently selected by growth on tetracycline, the marA47(Yp) gene was overexpressed. The findings suggest that marA47(Yp) is a marA ortholog in Y. pestis.

    Full Text Available A simple, rapid analytical method for determining traces of Cd, Cr, Cu, Mn and Pb in in various types of vegetable oils is proposed. Samples are digested in a microwave oven and then analyzed by atomic absorption spectroscopy with electrothermal atomization. The proposed method exhibits good linearity and sensitivity to the five metals, which it can determine with detection limits over the range 0.06-2.15 Ìg/kg. Its precision, as relative standard deviation, ranges from 2.6 to 4.2%. Its accuracy was assessed by using it to analyze a reference material consisting of Used Oil HU-1, which contains certified metal concentrations, and was found to be quite acceptable. The proposed method was applied to the determination of the five metals in virgin olive, olive, sunflower, maize and pomace olive oils from Spain and Morocco. Based on the results, the metal contents varied among oil types and, for olive oil, also with the country of origin; the oil samples from Morocco contained especially high levels of lead.En el presente trabajo se propone un método simple y rápido de análisis para la determinación de trazas metálicas (Cd, Cr, Cu, Mn, y Pb en diferentes tipos de aceites vegetales.

El método ofrece una buena linealidad y sensibilidad para los cinco metales determinados, con límites de detección comprendidos entre 0,06- 2,15 μg/kg. La precisión del método expresada como desviación estándar relativa oscila entre 2,6 y 4,2 %. Para el estudio de la exactitud se analizó un aceite de referencia (Used Oil HU-1 con las concentraciones de metales certificadas, obteniéndose unos resultados satisfactorios.

    Ionization chambers are widely used in diagnostic radiology dosimetry. In this work, a special pencil-type ionization chamber, with different dimensions, configuration and materials in relation to commercial ones, was studied computationally. For this, the MCNP-4C Monte Carlo code and different radiation spectra were used to determine the influence of its components on its response. It was possible to observe that the highest influence was for the PVC wall. (author)

    Full Text Available This paper describes an efficient implementation of multiple-target multiple-view tracking in video-surveillance sequences. It takes advantage of the capabilities of multiple core Central Processing Units (CPUs and of graphical processing units under the Compute Unifie Device Arquitecture (CUDA framework. The principle of our algorithm is 1 in each video sequence, to perform tracking on all persons to track by independent particle filters and 2 to fuse the tracking results of all sequences. Particle filters belong to the category of recursive Bayesian filters. They update a Monte-Carlo representation of the posterior distribution over the target position and velocity. For this purpose, they combine a probabilistic motion model, i.e. prior knowledge about how targets move (e.g. constant velocity and a likelihood model associated to the observations on targets. At this first level of single video sequences, the multi-threading library Threading Buildings Blocks (TBB has been used to parallelize the processing of the per-target independent particle filters. Afterwards at the higher level, we rely on General Purpose Programming on Graphical Processing Units (generally termed as GPGPU through CUDA in order to fuse target-tracking data collected on multiple video sequences, by solving the data association problem. Tracking results are presented on various challenging tracking datasets.Este artículo describe una implementación eficiente de un algoritmo de seguimiento de múlti­ples objetivos en múltiples vistas en secuencias de video vigilancia. Aprovecha las capacidades de las Unidades Centrales de Procesamiento (CPUs, por sus siglas en inglés de múltiples núcleos y de las unidades de procesamiento gráfico, bajo el entorno de desarrollo de Arquitec­tura Unificada de Dispositivos de Cómputo (CUDA, por sus siglas en inglés. El principio de nuestro algoritmo es: 1 aplicar el seguimiento visual en cada secuencia de video sobre todas las personas a seguir con filtros de partículas independientes y 2 fusionar los resultados de se­guimiento de todas las secuencias. Los filtros de partículas pertenecen a la categoría de filtros Bayesianos recursivos. Actualizan una representación Monte-Carlo de la distribución posterior sobre la posición y la velocidad de los objetivos. Para este fin, combinan un modelo probabi­lístico de movimiento, es decir un conocimiento a priori de como se mueven los objetivos (por ej. velocidad constante y un modelo de verosimilitud asociado con las observaciones de los objetivos. En este primer nivel de procesamiento de las secuencias de video simples, la librería multi-hilo (TBB, por sus siglas en inglés es utilizada para paralelizar el procesamiento de los filtros de partículas asociados a cada objetivo. Luego, al nivel superior, utilizamos Programa­ción de Propósito General con Unidades de Procesamiento Gráficas (conocido por su acrónimo en inglés GPGPU a través de CUDA con el fin de fusionar los datos del seguimiento de objetivos colectados entre las diferentes secuencias de video, al resolver el problema de asociación de datos. Los resultados del seguimiento son presentados en algunas bases de datos desafiantes.

    Brazil has a growing demand for nuclear medicine services (NMS), and radiopharmaceuticals supplied by the National Nuclear Energy Commission (CNEN) provide approximately two million nuclear medicine (NM) procedures per year. Among these radiopharmaceuticals, one of the most used is {sup 99m}Tc. The manipulation of unsealed radioactive sources presents a risk of incorporation. Workers who handle radiopharmaceuticals in NM procedures should be subject to an internal individual monitoring program to optimize their practices as well as to ensure that dose limits are not exceeded. This program may require measuring the activity of incorporated radionuclides, done in a whole body counter. This measurement may prove impracticable due to the absence of dedicated systems, available to all workers in a country. One solution to this problem would be to perform the measurement of the incorporated activity using the Gamma camera of the NMS in which the occupationally exposed individual (IOE) works. The objective of this work is to simulate with the Monte Carlo method a Gamma camera, with the code Gate, validating the results for the {sup 99m}Tc through measurements performed in an NMS. Measurements of counts were taken around the 140 keV main peak, with and without the collimator, that were correlated with the source activity. The validation shows good agreement between the simulation and the experimental data, with a difference of about 3% for the simulation without the collimator and about 2% for the simulation with the collimator.

    Full Text Available Gaseous mercury sampling conditions were optimized and a dynamic flux chamber was used to measure the air/surface exchange of mercury in some areas of the Negro river basin with different vegetal coverings. At the two forest sites (flooding and non-flooding, low mercury fluxes were observed: maximum of 3 pmol m-2 h-1 - day and minimum of -1 pmol m-2 h-1 - night. At the deforested site, the mercury fluxes were higher and always positive: maximum of 26 pmol m-2 h-1 - day and 17 pmol m-2 h-1 - night. Our results showed that deforestation could be responsible for significantly increasing soil Hg emissions, mainly because of the high soil temperatures reached at deforested sites.

    Calorimetry Hadronic with semidigital reading based on camera of resistive planes of glass for experiments on collision linear e + e-. Electron-positron linear colliders have been proposed as next generation particle colliders to complement and extend the physics programme of the LHC (Large Hadron Collider) at CERN. Currently, two projects, ILC (International Linear Collider) and CLIC (Compact LInear Collider), have been suggested by the international community to reach this purpose. The requirements for a detector for both linear colliders are defined by the precision needed to fully exploit the physics potential of these colliders. In particular, one of the most important requirements is an excellent jet energy resolution. This can be achieved with the particle-flow concept in which the overall detector performance for jet reconstruction is optimised by reconstructing each particle individually. For this reason, the calorimeter system has to have unprecedented granularity fulfilling the task of shower separation and providing excellent jet energy resolution and background separation.

    Full Text Available O golpe de Estado no Chile teve um grande impacto fora das fronteiras nacionais, podendo ser caracterizado como um “evento-mundo”. No caso das televisões e dos cineastas estrangeiros, o 11 de setembro de 1973 motivou a realização de reportagens e filmes que denunciassem a repressão no país sul-americano, visando a desconstruir a imagem de um cotidiano “normalizado” que os militares procuravam vender para o exterior. Na segunda metade dos anos 1970, indo mais além da denúncia, essa produção audiovisual estrangeira se dedicou a compreender os processos de recomposição da vida social e de criação de uma nova ideologia nos grupos sociais (especialmente por meio do fortalecimento do gremialismo, fatores que permitiam uma longa duração para o regime de segurança nacional. Diante desse cenário, este artigo analisa fontes audiovisuais filmadas no Chile por diretores estrangeiros logo após o golpe e o posterior documentário feito pela TV suíça Chili: ordre, travail, obéissance (1977, com o objetivo de compreender as representações que esses materiais fazem da cotidianidade durante a ditadura de Pinochet nesses dois momentos. Rodadas sob a vigia da Junta Militar, essas fontes se valeram de muitas cenas da vida cotidiana chilena, já que muitas vezes essas eram as imagens possíveis de serem registradas no contexto da repressão. Porém, montadas no exterior do país, essas cenas foram usadas em filmes e reportagens para contrapor o discurso da “normalização” que os militares desejavam passar para a opinião pública internacional

    A Tandem system consists of the use of different energy dependent dosimeters, where the ratio of the responses of the calibration curves to energy provides the effective energy of the beam. The efficiency of this system is related to the uncertainties inherent in the dosimeter used and the degree of energy dependence of each set. The greater the slope of the Tandem curve the better will be the identification of values close to HVL making the system useful. In this work, the Tandem system consists of ionization chamber of the pencil type and cylindrical absorber layers of materials with different energetic dependencies, for application in computed tomography.

    Full Text Available Minilivestock, village development and the role of BEDIM.Minilivestock encompasses all animals of small site, and little-known in terras of production but usable as food, feed or revenues if not eaten. Sustainable breeding becomes possible, and should progressively replace uncontrolled gathering in the wild. Amongst vertebrates, an important meat supply is based on edible rodents like Thryonomys, Cricetomys, Xerus, Atherurus, Tenrec; Hydrochoerus, Dasyprocta, Myocastor, Capromys, Dolichotis, Agouti, etc. The saine applies to the guinea-pig Cavia porcellus and to frogs. Invertebrates farming is also practised through breeding of maggots, termites, butterflies (pupae and adults for consumption or sale; giant snails are also highly appreciated in many African countries. Minilivestock development is usually a back-yard activity, hence its interest as it relies on local species, substrates and raw materials for infrastructure. The demand for minilivestock product is high but there is still reluctance often from the official authorities, unfortunately. However minilivestock is not an utopia, and a country like Papua-New-Guinea, which bas officially adopted minilivestock production as a tool to help to develop remote villages, is an excellent example of success

    The ecological function of animal seed dispersal depends on species interactions and can be affected by drivers such as the management interventions applied to protected areas. This study was conducted in two protected areas in the Monte Desert: a fenced reserve with grazing exclusion and absence of large native mammals (the Man and Biosphere Ñacuñán Reserve; FR) and an unfenced reserve with low densities of large native and domestic animals (Ischigualasto Park; UFR). The study focuses on Prosopis flexuosa seed removal by different functional mammal groups: “seed predators”, “scatter-hoarders”, and “opportunistic frugivores”. Under both interventions, the relative contribution to seed removal by different functional mammal groups was assessed, as well as how these groups respond to habitat heterogeneity (i.e. vegetation structure) at different spatial scales. Camera traps were used to identify mammal species removing P. flexuosa seeds and to quantify seed removal; remote sensing data helped analyze habitat heterogeneity. In the FR, the major fruit removers were a seed predator (Graomys griseoflavus) and a scatter-hoarder (Microcavia asutralis). In the UFR, the main seed removers were the opportunistic frugivores (Lycalopex griseus and Dolichotis patagonum), who removed more seeds than the seed predator in the FR. The FR shows higher habitat homogeneity than the UFR, and functional groups respond differently to habitat heterogeneity at different spatial scales. In the FR, because large herbivores are locally extinct (e.g. Lama guanicoe) and domestic herbivores are excluded, important functions of large herbivores are missing, such as the maintenance of habitat heterogeneity, which provides habitats for medium-sized opportunistic frugivores with consequent improvement of quality and quantity of seed dispersal services. In the UFR, with low densities of large herbivores, probably one important ecosystem function this group performs is to increase

    Leptospirosis is a growing public and veterinary health concern caused by pathogenic species of Leptospira. Rapid and reliable laboratory tests for the direct detection of leptospiral infections in animals are in high demand not only to improve diagnosis but also for understanding the epidemiology of the disease. In this work we describe a novel and simple TaqMan-based multi-gene targeted real-time PCR approach able to detect and differentiate Leptospira interrogans, L. kirschneri, L. borgpeteresenii and L. noguchii, which constitute the veterinary most relevant pathogenic species of Leptospira. The method uses sets of species-specific probes, and respective flanking primers, designed from ompL1 and secY gene sequences. To monitor the presence of inhibitors, a duplex amplification assay targeting both the mammal β-actin and the leptospiral lipL32 genes was implemented. The analytical sensitivity of all primer and probe sets was estimated to be <10 genome equivalents (GE) in the reaction mixture. Application of the amplification reactions on genomic DNA from a variety of pathogenic and non-pathogenic Leptospira strains and other non-related bacteria revealed a 100% analytical specificity. Additionally, pathogenic leptospires were successfully detected in five out of 29 tissue samples from animals (Mus spp., Rattus spp., Dolichotis patagonum and Sus domesticus). Two samples were infected with L. borgpetersenii, two with L. interrogans and one with L. kirschneri. The possibility to detect and identify these pathogenic agents to the species level in domestic and wildlife animals reinforces the diagnostic information and will enhance our understanding of the epidemiology of leptopirosis.

  7. Simulation of a hypothetical core disruptive accident in the mars test-facility

    International Nuclear Information System (INIS)

    Robbe, M.F.; Lepareux, M.

    2001-01-01

    In France, a large experimental programme MARA/MARS was undertaken in the 80's to estimate the mechanical consequences of an HCDA (Hypothetical Core Disruptive Accident) and to validate the SIRIUS computer code used at that time for the numerical simulations. At the end of the 80's, it was preferred to add a HCDA sodium-bubble-argon tri-component constitutive law to the general ALE fast dynamics finite element CASTEM-PLEXUS code rather than going on developing and using the specialized SIRIUS code. The experimental results of the MARA programme were used in the 90's to validate and qualify the CASTEM-PLEXUS code. A first series of computations of the tests MARA 8, MARA 10 and MARS was realised. The simulations showed a rather good agreement between the experimental and computed results for the MARA 8 and MARA 10 tests - even if there were some discrepancies - but the prediction of the MARS structure displacements and strains was overestimated. This conservatism was supposed to come from the fact that several MARS non axisymmetric structures like core elements, pumps and heat exchangers were not represented in the CASTEM-PLEXUS model. These structures, acting as porous barriers, had a protective effect on the mock-up containment by absorbing energy and slowing down the fluid impacting the containment. For these reasons, we developed in CASTEM-PLEXUS a new HCDA constitutive law taking into account the presence of the internal structures (without meshing them) by means of an equivalent porosity method. In other respects, the process used for dealing with the fluid-structure coupling in CASTEM-PLEXUS was improved. Thus a second series of simulations of the tests MARA8 and MARA10 was realised. A simulation of the test MARS was carried out too with the same simplified representation of the peripheral structures as in order to estimate the improvement provided by the new fluid-structure coupling. This paper presents a third numerical simulation of the MARS test with the

    Full Text Available OBJETIVO: A fim de simplificar a utilização das tabelas correspondentes aos fatores de qualidade no TRS-398 da International Atomic Energy Agency na calibração cruzada da câmara de placas paralelas por comparação com uma câmara cilíndrica calibrada em um feixe de elétrons de qualidade Qcross, é introduzida uma energia intermediária e arbitrária Qint na qual a câmara de placas paralelas deverá ser calibrada. O objetivo deste trabalho consiste em avaliar a escolha desta energia intermediária. MATERIAIS E MÉTODOS: Uma câmara de placas paralelas da Scanditronix, modelo NACP-02, e uma câmara PTW Markus foram calibradas em dois aceleradores lineares da Varian, Clinac 2100C e Clinac 23EX, nas energias de 16 e 20 MeV, respectivamente. Como câmara de referência foi utilizada uma câmara da Nuclear Enterprises, modelo 2571, previamente calibrada em termos de Dw no Instituto de Pesquisas Energéticas e Nucleares, para um feixe de 60Co. RESULTADOS: Os fatores de calibração N D,w assim obtidos apresentam uma variação de 0,07%, o que pode ser considerado desprezível. Os valores de dose absorvida na água determinados no Clinac 2100C para uma Qint de 16 MeV apresentam uma variação de 0,04% para a menor energia (4 MeV e de 2,6% para a maior energia (16 MeV, em relação ao protocolo TRS-381. Já para uma Qint de 20 MeV, as variações observadas são de 1,3% e 3,5%. Por outro lado, as doses determinadas no Clinac 23EX para as Qint de 16 MeV e de 20 MeV são de 1,9% e 2,0% e de 2,8% e 3,0%, respectivamente. CONCLUSÃO: A escolha de Qint não é tão crítica assim, principalmente quando não de dispõem de feixes de elétrons que tenham na prática um valor de R50 exatamente igual a 7,5 g.cm-2.

  3. Rapid evolution of ritual architecture in central Polynesia indicated by precise 230Th/U coral dating.

    Science.gov (United States)

    Sharp, Warren D; Kahn, Jennifer G; Polito, Christina M; Kirch, Patrick V

    2010-07-27

    In Polynesia, the complex Society Islands chiefdoms constructed elaborate temples (marae), some of which reached monumental proportions and were associated with human sacrifice in the 'Oro cult. We investigated the development of temples on Mo'orea Island by 230Th/U dating of corals used as architectural elements (facing veneers, cut-and-dressed blocks, and offerings). The three largest coastal marae (associated with the highest-ranked chiefly lineages) and 19 marae in the inland 'Opunohu Valley containing coral architectural elements were dated. Fifteen corals from the coastal temples meet geochemical criteria for accurate 230Th/U dating, yield reproducible ages for each marae, and have a mean uncertainty of 9 y (2sigma). Of 41 corals from wetter inland sites, 12 show some diagenesis and may yield unreliable ages; however, the majority (32) of inland dates are considered accurate. We also obtained six 14C dates on charcoal from four marae. The dates indicate that temple architecture on Mo'orea Island developed rapidly over a period of approximately 140 y (ca. AD 1620-1760), with the largest coastal temples constructed immediately before initial European contact (AD 1767). The result of a seriation of architectural features corresponds closely with this chronology. Acropora coral veneers were superceded by cut-and-dressed Porites coral blocks on altar platforms, followed by development of multitier stepped altar platforms and use of pecked basalt stones associated with the late 'Oro cult. This example demonstrates that elaboration of ritual architecture in complex societies may be surprisingly rapid.

    Full Text Available Durante o armazenamento, vários fungos podem permanecer associados às sementes de milho, causando deterioração ou se mantendo viáveis, infectando posteriormente a plântula. Objetivou-se neste trabalho verificar a sobrevivência de fungos associados às sementes de milho durante 12 meses de armazenamento, em câmara fria (14ºC; 40% UR e em ambiente não controlado. Observaram-se com maior freqüência os fungos de campo Alternaria alternata, Bipolaris maydis, Cephalosporium acremonium, Cladosporium herbarum, Fusarium moniliforme e Rhizoctonia solani, além de Rhizopus spp. e Trichoderma spp., cuja sobrevivência decresceu ao longo do armazenamento, de modo muito mais acentuado em condição de ambiente não controlado, em comparação à câmara fria. Aspergillus e Penicillium tiveram suas incidências aumentadas ao longo do período, principalmente em ambiente não controlado. Nessa condição, a sobrevivência de Fusarium moniliforme foi reduzida gradativamente até o final dos doze meses; comparativamente, em câmara fria, a viabilidade do fungo foi menos afetada. Bipolaris maydis manteve-se viável na maioria dos lotes, durante todo o armazenamento em câmara fria; em ambiente não controlado, o fungo sobreviveu durante quatro a dez meses, dependendo do lote avaliado. O armazenamento em ambiente não controlado, embora tenha provocado a redução do inóculo de F. moniliforme e outros fungos importantes, poderia acelerar o processo de deterioração das sementes. Em câmara fria, por outro lado, a viabilidade dos fungos é favorecida, comprometendo a qualidade sanitária das sementes.

    Alexsandro Santana Vieira

    2007-12-01

    Full Text Available Para descrever o padrão de construção e ocupação dos ninhos de Ectatomma vizottoi, foram escavados oito ninhos durante o período de novembro de 2004 a agosto de 2006, em Dourados-MS. Os orifícios de entrada ou saída dos ninhos desta espécie possuem formato elipsóide, com acesso a um túnel alargado, similar a uma antecâmara, a qual é conectada a câmaras mais profundas do ninho. Os ninhos podem alcançar até 360,0 cm de profundidade, e apresentam de três a dez câmaras. São construídos independentemente de raízes de plantas, e o solo de seus túneis e câmaras é compactado, apresentando compartimentos específicos para depósitos de detritos da colônia. O aumento da densidade de formigas conduz a um aumento do número de câmaras, bem como da profundidade do ninho, mantendo, entretanto, um volume médio para o mesmo, evidenciando um padrão para o tamanho das câmaras dos ninhos.The construction pattern and occupancy of Ectatomma vizottoi was described, during November 2004-August 2006 period, in Dourados, state of Mato Grosso do Sul by excavation of eight nests. The entrance openings, or exit, have an ellipsoid shape and lead to a wide tunnel, similar to a hall, which is connected to other deeper chambers in the nest. The nests reach up to 360 cm deep and contain three to ten chambers. Nests are constructed independently of plants and roots presence, and the soil of the tunnels and chambers are compacted, with specific compartments for colony deposit of detritus. The increase of the ant density led to an increase in nest depth and number of chambers, maintaining an average nest volume, which indicates a standard size for nest chambers.

Son los integrantes, en casi su totalidad, alumnos avanzados del conservatorio, pero cuando actúan, como nos consta, lo hacen en un nivel mucho más elevado, comparable, por cierto, al de los grandes y tradicionales conjuntos que más pesan en el arte de la música de cámara.

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

    Dry forest bird communities in South America are often fragmented by intervening mountains and rainforests, generating high local endemism. The historical assembly of dry forest communities likely results from dynamic processes linked to numerous population histories among codistributed species. Nevertheless, species may diversify in the same way through time if landscape and environmental features, or species ecologies, similarly structure populations. Here we tested whether six co-distributed taxon pairs that occur in the dry forests of the Tumbes and Marañón Valley of northwestern South America show concordant patterns and modes of diversification. We employed a genome reduction technique, double-digest restriction site-associated DNA sequencing, and obtained 4407-7186 genomewide SNPs. We estimated demographic history in each taxon pair and inferred that all pairs had the same best-fit demographic model: isolation with asymmetric gene flow from the Tumbes into the Marañón Valley, suggesting a common diversification mode. Overall, we also observed congruence in effective population size (N e ) patterns where ancestral N e were 2.9-11.0× larger than present-day Marañón Valley populations and 0.3-2.0× larger than Tumbesian populations. Present-day Marañón Valley N e was smaller than Tumbes. In contrast, we found simultaneous population isolation due to a single event to be unlikely as taxon pairs diverged over an extended period of time (0.1-2.9 Ma) with multiple nonoverlapping divergence periods. Our results show that even when populations of codistributed species asynchronously diverge, the mode of their differentiation can remain conserved over millions of years. Divergence by allopatric isolation due to barrier formation does not explain the mode of differentiation between these two bird assemblages; rather, migration of individuals occurred before and after geographic isolation. © 2017 John Wiley & Sons Ltd.

    Full Text Available O município de Rio Grande (RS foi considerado “área de segurança nacional” durante o regime civil-militar (1964-1985, o que, entre outras implicações, fazia com que o prefeito fosse nomeado e só ocorressem eleições diretas para a Câmara de Vereadores. No período de redemocratização (1983-1985, PMDB e PDT, os partidos de oposição à ditadura e ao chefe do executivo municipal, tinham maioria das cadeiras e realizavam o enfrentamento ao PDS, legenda do prefeito e de apoio ao golpe de 1964. A pesquisa tem como objetivo analisar os embates ocorridos na Câmara de Vereadores de Rio Grande entre essas forças políticas, no contexto do término da ditadura. Utiliza como fontes a análise das atas da Câmara Municipal, nas quais foram encontrados elementos que resgatam a história do período e demonstram que a oposição denunciava as condições nas quais se encontrava o município e o país, além de alimentar um sentimento de união entre os partidos que lutavam pelo retorno da democracia no Brasil, enquanto os vereadores governistas evitavam ingressar nesse debate.

    Directory of Open Access Journals (Sweden)

    Heather R. Cunningham

    2012-01-01

    Full Text Available Declines of amphibian and reptile populations are well documented. Yet a lack of understanding of their distribution may hinder conservation planning for these species. The Maryland Amphibian and Reptile Atlas project (MARA was launched in 2010. This five-year, citizen science project will document the distribution of the 93 amphibian and reptile species in Maryland. During the 2010 and 2011 field seasons, 488 registered MARA volunteers collected 13,919 occurrence records that document 85 of Maryland's amphibian and reptile species, including 19 frog, 20 salamander, five lizard, 25 snake, and 16 turtle species. Thirteen of these species are of conservation concern in Maryland. The MARA will establish a baseline by which future changes in the distribution of populations of native herpetofauna can be assessed as well as provide information for immediate management actions for rare and threatened species. As a citizen science project it has the added benefit of educating citizens about native amphibian and reptile diversity and its ecological benefits—an important step in creating an informed society that actively participates in the long-term conservation of Maryland's nature heritage.

    Glossina swynnertoni is a savannah tsetse that is largely confined to the Serengeti-Mara [a very small part of East Africa covering northern Tanzania (Arusha and Manyara regions and parts of Shinyanga and Mara regions) extending Maasai Mara ecosystem in southwestern Kenya]. Nevertheless, it is of great concern to human and animal health and is one of the top target tsetse species for eradication. To achieve this eradication objective, it is important to know about its behaviour so that the appropriate tools/measures especially the right traps can be applied against it. In this paper G. swynnertoni is reviewed in terms of its behaviour, and development of traps for its survey and control. Glossina swynnertoni control is of paramount importance in Tanzania tourism industry and country's income. Since, G. swynnertoni is also distributed in national parks, control is vital as it might reduce tourists excursion/movement, by transmitting the African trypanosomiasis among travelers. Different literature search engines such as Google Scholar and PubMed were deployed for literature search. It was found that the behaviour of G. swynnertoni is relatively similar but unique from other tsetse flies. Its feeding cycle is 2½-3 days as opposed to 3-4 days observed in other tsetse species. The flight activity pattern varied between sex, with male having their peak at 1100-1200 hrs and females 1400-1600 hrs. The activity in both sexes decline rapidly towards the dusk (1700-1800 hrs). It was further that host odours, relatively smaller and vertically oriented devices, as well as host movement are the main attractive factors to this tsetse species, which can be exploited to design efficient artificial devices for control of G. swynnertoni . Therefore, due to its restricted distribution and threat it poses on tourism industry, deliberate efforts need to be made against G. swynnertoni as a next candidate to be eradicated using artificial bait technology.

    Full Text Available O objetivo do presente trabalho foi avaliar a influência da secagem e do armazenamento de sementes de pinhão-manso na qualidade do óleo produzido. O experimento de secagem foi realizado com 5 variações de temperatura: 30, 40, 50, 60 e 70 °C, até a umidade de 9,3 ± 1,1% de base seca. O experimento de armazenamento foi realizado variando-se a condição e armazenamento: Ambiente do Laboratório (26 ± 3 °C; 55 ± 12% UR, Câmara Refrigerada do tipo B.O.D. (5 ± 1 °C; 79 ± 5% UR e Câmara Climatizada com aparelho de ar condicionado (18 ± 1 °C; 53 ± 7% UR; e o tempo de armazenamento: 2 e 4 meses. Os óleos foram avalizados em teor de óleo e os índices de acidez, peróxido e iodo. A secagem das sementes proporcionou elevação considerável no potencial de rancificação em temperaturas maiores ou iguais a 30 °C, revelando que secagens à temperaturas menores recomendável. Os armazenamentos das sementes nas câmaras climatizadas e refrigeradas apresentaram perdas na qualidade do óleo, com alto potencial de rancificação e de hidrólise dos óleos, respectivamente, revelando que o armazenamento em condições naturais é a mais indicada na manutenção da qualidade do óleo de pinhão-manso.

    Full Text Available Evidências significativas sugerem a inter-relação existente entre a região de furca de dentes multirradiculados com o desenvolvimento de lesões endo-periodontais, principalmente, quando da presença do canal cavo-inter-radicular. Com o objetivo de compreender os mecanismos envolvidos na etiopatogenia de tais doenças periodontais, assim como propiciar o diagnóstico e o tratamento precoces, buscou-se melhor caracterizar essa região dando ênfase à morfologia do assoalho da câmara pulpar. Para este estudo foram selecionados 42 molares humanos extraídos, sendo 21 superiores e 21 inferiores. Após realizadas as aberturas coronárias e localizadas as entradas dos canais radiculares, os dentes tiveram parte das porções coronária e radicular cortada perpendicularmente ao longo do seu eixo, com o auxílio de disco de carburundum. Depois de uma criteriosa limpeza dos espécimes, esses foram secos em câmara de ponto crítico, sendo, a seguir, preparados para análise em microscópio eletrônico de varredura (Philips®, modelo XL30, Holanda. Os dados foram analisados através do Teste U de Mann- Whitney e do teste Qui-quadrado. Com base nos resultados obtidos e de acordo com a literatura pertinente, pôde-se verificar que: 1. o diâmetro e o número de túbulos dentinários encontrados por mm2 assim como a presença de foraminas no assoalho da câmara pulpar sugerem a permeabilidade dessa região; 2. o diâmetro maior de algumas foraminas identifica a presença do canal cavo-inter-radicular

  8. Estimation of the mechanical effects of a core disruptive accident on a LMFBR

    In case of a Hypothetical Core Disruptive Accident (HCDA) in a Liquid Metal Reactor, the interaction between fuel and liquid sodium creates a high pressure gas bubble in the core. The violent expansion of this bubble loads the vessel and the internal structures, whose deformation is important. In order to demonstrate the CASTEM-PLEXUS capability to predict the behaviour of real reactors], axisymmetric computations of the MARA series were confronted with the experimental results. The computations performed at the beginning of the years 90 showed a rather good agreement between the experimental and computed results for the MARA 8 and MARA 10 tests even if there were some discrepancies which might be eliminated by increasing the fineness of the mesh. On the contrary, the prediction of the MARS structure displacements and strains was overestimated. This conservatism was supposed to come from the fact that several MARS non axisymmetric structures like core elements, pumps and heat exchangers were not represented in the CASTEM-PLEXUS model. These structures, acting as porous barriers, had a protective effect on the containment by absorbing energy and slowing down the fluid impacting the containment. For these reasons, we developed in CASTEM-PLEXUS a new HCDA constitutive law taking into account the presence of the internal structures (without meshing them) by means of an equivalent porosity method and we simulated the MARS test another time with the new HCDA constitutive law. This paper presents the numerical results relative to the structure behaviour during the accident. The results are described through the evolution of several variables versus time: deformed shape of the structures and the mesh, displacements, stresses and plastic strains. (author)

    Patients as Experts: Determining Benefit by Using Assessments of Ability (ICIDH)When health economy and quality mangement are dealing with the cost-benefit relationship, to this day description, calculation, and assessment of the benefit are missing to a great extent. Deliberations in terms of cause and effect do not go beyond the model of pathogenesis (etiology - pathology - manifestation) and descriptions on the organ level (ICD). Only the international classification of impairments, disabilities, and handicaps (ICIDH) as a separate estimation of the resulting manifestations of illness on the levels of organ, individual, and society is capable to elucidate this benefit. It is the patient who is the expert to decide what he needs, what he wants, and what he can do, thus, evaluating on an individual level his loss of capability. The ICIDH is regarded as the key for the management of chronic diseases. The characteristics of being chronically ill require the integration of salutogenesis and the consideration of the hierarchy of needs. The specially developed MARA model serves as pragmatic basis for the description of the benefits of carried out and omitted interventions as changes of abilities by using the MARA curve (mean age-related ability) as ethical guideline. In quality circles the MARA model, which is based on ICIDH, hierarchy of needs and salutogenesis, can offer apatient-oriented basis of discussion for benefit assessments, and, in a pragmatical way, it can facilitate the introduction of evidence-based medicine. By the change of view from the organ level with multifactorial aspects to the individual level, in which the abilities can be understood as a monofactor, a high consensus potential between several participants of discussion in health service is possible.

    Intrinsic mechanisms leading to carbapenem-induced membrane impermeability and multidrug resistance are poorly understood in clinical isolates of Enterobacteriaceae. In this study, molecular behaviours during the establishment of membrane impermeability in members of the Enterobacteriaceae family under imipenem selective pressure were investigated. Clinical isolates (n = 22) exhibiting susceptibility to multiple antibiotics or characterised as extended-spectrum β-lactamase (ESBL)- or AmpC-producers were submitted to progressive passages on Mueller-Hinton agar plates containing subclinical concentrations of imipenem [0.5 × the minimum inhibitory concentration (MIC)]. Changes in outer membrane permeability were evaluated by determination of antimicrobial MICs, sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE), and gene expression analysis related to membrane permeability (i.e. omp35-like, omp36-like and acrA) and regulatory mechanisms (i.e. marA and ompR) by quantitative reverse transcription PCR. Following imipenem induction, 73% of isolates showed increased carbapenem MICs by ≥2 doubling dilutions. At an early stage of treatment, imipenem modulated the expression of porins and efflux pump genes, represented by a reduction of 78% in omp36-like and a two-fold increase in acrA expression. Transcriptional factors marA and ompR were also affected by imipenem induction, increasing mRNA expression by 14- and 4-fold, respectively. High marA expression levels were associated with higher values of acrA expression. These results suggest that imipenem is an important factor in the development of an adaptive response to carbapenems by regulating key genes involved in the control of efflux pumps and porins, which could lead to a multidrug-resistant profile in clinical isolates, contributing to possible treatment failure.

    Sánchez, A.

    2010-12-01

    Full Text Available This report analyses the influence of the use of an inert gas welding chamber with a totally inert atmosphere on the microstructure and mechanical properties of austenitic AISI 316L stainless steel TIG welds, using AISI ER316L, AISI 308L and Inconel 625 as filler metals. When compared with the typical TIG process, the use of the inert gas chamber induced changes in the microstructure, mainly an increase in the presence of vermicular ferrite and ferrite stringers, what resulted in higher yield strengths and lower values of hardness. Its effect on other characteristics of the joins, such as tensile strength, depended on the filler metal. The best combination of mechanical characteristics was obtained when welding in the inert gas chamber using Inconel 625 as filler metal.

    En este estudio se analiza la influencia que el uso de una cámara de soldadura de gas inerte tiene sobre la microestructura y las propiedades mecánicas de las soldaduras TIG en el acero inoxidable austenítico AISI-316L cuando se emplean AISI ER316L, AISI 308L e Inconel 625 como materiales de aporte. Cuando se compara con el típico proceso de TIG, el uso de una cámara de gas inerte induce cambios en la microestructura, incrementando la presencia de ferrita vermicular y de laminillas de ferrita, resultando en un aumento del límite elástico y una pérdida de dureza. Su influencia sobre otras características de las soldaduras como la carga de rotura depende de la composición del material de aporte. La mejor combinación de propiedades mecánicas se obtuvo usando el Inconel 625 como material de aporte y soldando en la cámara de gas inerte.

    The Mars Exploration Rover Opportunity has been exploring the western rim of the 22 km diameter Endeavour crater since August, 2011. Recently, Opportunity has reached a break in the Endeavour rim that the rover team has named Mara-thon Valley. This is the site where orbital observations from the MRO CRISM imaging spectrometer indicated the presence of iron smectites. On the outer western portion of Marathon Valley, Opportunity explored the crater-form feature dubbed Spirit of St. Louis (SoSL) crater. This presentation describes the 430 to 1009 nm (VNIR) reflectance, measured by the rover's Pancam, of rock units present both at Spirit of St. Louis and within Marathon Valley.
