Description
An account of the resource
Muchos son los posibles contagios entre el pensamiento de Deleuze y el campo de la educación. Y más aún si asimilamos la dimensión del aprendizaje en tanto implicación y complicación inherente al ejercicio de pensar, como la invención de relaciones no dadas entre heterogéneos. Es decir, si hay pensamiento no solo hay movimiento, pero sobre todo, apre(he)nder inmanente que doblemente es expresión. Es así como podríamos hablar con Deleuze de 'pensar por el medio' como pedagogía radical y en acto. El texto a seguir fue compuesto a modo de performance filosófica, no solo como gesto de pedagogía radical al querer instaurarse como un plano de experiencia en devenir para el pensamiento, sino que esencialmente como contra-pedagogía en acto ante la forma-academia. A medio camino entre delirio como metodología y fabulación especulativa como fuerza creadora, que he nombrado 'Azul profundo', el texto a modo de critica inmanente se propone a experimentar otros modos de habitar la economía y ecología académica como gesto expresivo y de re-existencia.

Description
An account of the resource
As moscas-das-frutas são consideradas as p1incipais pragas da fruticultura no Brasil. Estes insetos reduzem a produção dos pomares e a qualidade das frntas, dificultando ou impedindo a expmtaçào de frutas in. natura. A flutuação populacional destas moscas foi acompanhada no período de outubro de 1999 a setembro de 2001, em dois pomares de laranjeiras da cultivar Valência situados nos municípios de Águas de Chapecó e Chapecó, SC. Para tanto, foram utilizados frascos 'caça-moscas' com vinagre de vinho tinto a 25% como atrativo alimentar. As amostras foram coletadas semanalmente e transportadas para o Laboratório de Fitossanidadc do Centro de Pesquisa para Agricultura Familiar - Cepaf - da Epagri, para identificação e contagem dos insetos. A captura de moscas totalizou 5.914 espécimes, sendo 5.706 do gênero Anastrepha (99% A fraterculus) e 208 indivíduos de Ceratitís capitata, com picos popuh!cionais ocorrendo no final do verão e no inverno. Os resultados das análises estatísticas de correlação e regressão polinomial entre as médias mensais de moscas capturadas e os dados médios mensais de temperatw·a, insolação, precipitação pluviométrica, umidade relativa do ar e velocidade dos ventos não foram satisfatórios para explicar as variações populacionais destes insetos. O manejo das moscas-das-frutas preconiza o seu monitoramento populacional e a adoção de práticas integradas capazes de manter baixas suas populações.

Con un volumen anual compuesto por dos números (enero-junio y julio-diciembre) está siendo editada, tanto en formato impreso como virtual, la revista científica SAGASTEGUIANA (ISSN: 2309-5644) desde el 2013. Esta revista que fue creada entusiastamente por docentes de las Cátedras de Investigación Científica del Departamento de Ciencias Biológicas y del Herbarium Truxillense (HUT) de la Universidad Nacional de Trujillo (UNT), para perennizar con justa razón en mérito a su dedicación a la ciencia botánica la imagen de nuestro querido profesor, Dr. Abundio Sagástegui Alva (1932 - 2012), tiene como objetivo difundir los resultados de investigaciones originales ejecutadas por alumnos, profesionales y docentes de la Facultad de Ciencias Biológicas en el campo de las ciencias naturales y de sus aplicaciones tecnológicas: zoología, botánica, ecología, evolución, genética, biotecnología, etc. Como sucede con varias revistas de la UNT, dentro de ellas REBIOL y REBIOLEST de la Facultad de Ciencias Biológicas, Sagasteguiana puede ubicarse en el portal de nuestra Casa de Estudios, en la sección Revistas formando parte del Repositorio, pues se halla integrada al Open Journal Systems (OJS) y, al juzgar la regurosidad científica con que están presentados los artículos, que incluye una cuidadosa selección de autores, se puede comprender que el futuro de esta revista es promisoria. Un aspecto de gran importancia que ha incorporado esta revista, a diferencia de la mayoría, es una sección “pedagógica”, es decir, temas de interés general que no necesriamente significan nuevos conocimientos, sino explicación de fenómenos que ya forman parte del conocimiento estado pero que requieren de un análisis profundo por profesionales experimentados. Esperamos que esta joven revista científica crezca como debería; para ello, por un lado debe aumentar su frecuencia de dos a cuatro números por volumen, y por otro, aumentar el ámbito hacia la internacionalidad sometiendo los artículos al arbitraje por pares y publicando un porcentaje apreciable de artículos de autores de instituciones distintas a la UNT. Estos dos aspectos contituyen requisitos ineludibles para procurar la indización en Scielo, que sería la organización más accesible dentro de otras entidades indizadoras aceptadas a nivel internacional. No dudamos que esto ocurrirá, si tenemos en cuenta la calidad de profesionales que están conduciendo la edición de Sagasteguiana.

En el texto se reivindica la figura de Otto Neurath como economista que, defendiendo la inconmensurabilidad de valores en el debate sobre el cálculo económico en una economía socialista de los años 1920-30 del pasado siglo XX, frente a Hayek o von Mises, estaba ya muy cerca de una perspectiva económico-ecológica (concretamente de una contabilidad energética y de materiales) con su concepto de Naturalrechnung.

Description
An account of the resource
Se ha propuesto que los ambientes de alta montaña son especialmente vulnerables al calentamiento global. La interacción de variables como déficit hídrico y las condiciones de temperatura ambiental puede restringir el intercambio gaseoso en zonas de alta-montaña. Debido a las distintas limitaciones abióticas que se encuentran en un gradiente altitudinal, se propone que el aumento de la temperatura afectará positivamente la fotosíntesis de la planta alto-andina Phacelia secunda en elevadas altitudes y negativamente a las plantas de bajas altitudes. En el presente estudio se evaluó el efecto del aumento de la temperatura ambiental sobre el intercambio gaseoso de P. secunda en dos altitudes: 2900 m y 3600 m. En cada altitud se expusieron seis individuos de P. secunda a un sistema de calentamiento pasivo denominado 'Open Top Chamber' (OTC) que aumenta la temperatura del aire en ca. 3°C. Adicionalmente, en cada altitud se seleccionaron otros seis individuos en espacios abiertos para utilizarlos como control y que se encontraban a 2 m de la OTC más cercana. En cada individuo se midió el intercambio gaseoso y el potencial hídrico xilemático. La temperatura ambiental fue en promedio 3,5°C mayor dentro de las OTC en ambas altitudes. En contraste, el potencial hídrico del suelo y de las plantas se redujo un 28% al interior de las OTC, pero sólo a 2900 m. En esta altitud, las tasas de fotosíntesis al interior de las OTC se redujeron un 40,7%, mientras que a 3600 m las tasas aumentaron un 24,4%. Los efectos diferenciales en las tasas de fotosíntesis debido a la temperatura fueron acompañados con cambios en la conductancia estomática. Esto sugiere que los efectos del calentamiento global sobre la fotosíntesis de P. secunda son contrastantes entre ambas altitudes debido a los efectos secundarios que éste tiene sobre la disponibilidad hídrica en cada altitud.High-alpine environments have been proposed as particularly vulnerable to global warming. The interaction of variables such as water deficit and temperature conditions may restrict gas exchange in high-alpine areas. Due to different abiotic constraints that occur at different elevations in the Andes of central Chile we hypothesize that the temperature increases will positively affect the photosynthesis of the high-Andean plant Phacelia secunda at high elevation but it will be negatively affected by warming at lower elevations. In this study we evaluated the effect of increased environmental temperature on the gas exchange of P. secunda at two contrasting elevations: 2900 m and 3600 m a.s.l. At each elevation we exposed six individuals of P. secunda to a passive warming system with 'Open Top Chamber' (OTC) that increased air temperature on ca. 3°C. Other six individuals we selected in open areas and maintained as control on each elevation. At both elevations, on each selected individual (i.e. within and outside OTCs) we measured gas exchange and xylem water potential. At both elevations air temperature was on average 3.5°C higher inside the OTC. In contrast, OTC reduced 28% the soil and xylem water potential only at 2900 m. The increased temperature inside the OTC reduced 40.7% gas exchange rates at 2900 m, but increased it 24.4% at 3600 m. These differential effects of warming on photosynthetic rates were accompanied by changes in stomatal conductance. This suggests that the effects of global warming on the photosynthesis of P. secunda at two contrasting altitudes are related with the concomitant changes on drought at each elevation.

Mediante RD N° 184-2011-Fac.CC.BB. se aprobó las Líneas de Investigación de la Facultad de Ciencias Biológicas, que habían sido previamente propuestas, discutidas, aprobadas y codificadas en un plenario en concordancia con lo propuesto en el Plan Nacional de Desarrollo. Las Líneas concordadas fueron: (i) Conservación y caracterización de germoplasma para el desarrollo de variedades mejoradas en calidad y producción, (ii) Caracterización y control integrado de las principales plagas y enfermedades, (iii) Cultivos andinos, frutales y plantas medicinales y (iv) Fermentaciones industriales, en el Sector Agricultura, Agroindustria y Agro-exportación; (i) Uso de tecnología para el uso sostenible de pastos y recursos hídricos y (ii) Prevención, control y erradicación de enfermedades endémicas, en el Sector Pecuario; (i) Mejoramiento de tecnologías de transformación y procesamiento de especies marinas para consumo humano directo y (ii) Aplicación de tecnologías en la calidad de moluscos bivalvos, en el Sector Acuicultura y Pesca; (i) Epidemiología y prevención de problemas de salud de mayor impacto y (ii) Nutrición y seguridad alimentaria, en el Sector Salud y Nutrición; (i) Conservación de la biodiversidad biológica; (ii) Biorremediación de suelos, agua y ambiente contaminados y (iii) Desarrollar y transferir tecnologías para la producción más limpia y la ecoeficiencia, en el Sector Biodiversidad y Calidad Ambiental; y (i) Inventario y evaluación de recursos hídricos convencionales y de fuentes hídricas no convencionales y (ii) Desarrollo de sistemas de gestión técnica para la asignación en el Sector Recursos Hídricos. Sin embargo, la investigación ejecutada por docentes y alumnos de la Facultad no tuvo en cuenta el total de Líneas propuestas y, en algunos casos, ninguna de ellas. Consideramos, entonces, que la presente gestión debería ratificar o modificar las mencionadas Líneas puesto que formalmente siguen vigentes, hacer conocer su existencia a través del Sistema de Información y Comunicaciones y, en lo posible, establecer la concordancia con las investigaciones propuestas a comienzo de año por docentes y en su oportunidad por alumnos en los proyectos de Tesis, a fin de resolver lo que se ha venido siendo un prolongado reclamo: solucionar mediante la investigación los problemas de la sociedad.

Description
An account of the resource
Microbacterium esteraromaticum es un microorganismo que se aísla con frecuencia de Jandfarming o procesos de biorremediación de hidrocarburos en la meseta de la Patagonia central (Argentina) y se halla sometido a variaciones de temperatura y a cambios de salinidad que se producen naturalmente. Su adaptabilidad a esos cambios climáticos indujo al estudio de las modificaciones que se producen en su membrana celular para resistirlos. En este trabajo se estudió el efecto conjunto de la temperatura y la concentración de cloruro de sodio sobre la composición de los ácidos grasos de membrana en la cepa de Microbacterium esteraromaticum GNP-5b. M. esteraromaticum utiliza, frente al incremento de la temperatura, la estrategia es aumentar la longitud de sus ácidos grasos de cadenas ramificada impar (17 átomos de carbono) con disminución de 15:0 anteiso, así como el porcentaje de ácidos grasos 15:0 iso (de mayor punto de fusión) a partir del respectivo anteiso. El aumento de la salinidad modifica la composición de ácidos grasos siguiendo patrones diferentes según sea la temperatura de incubación. A 14 Y28 oc incrementa los 15:0 iso y 17:0 iso en detrimento de sus homólogos anteiso. A 37 'C este grupo de ácidos grasos no sigue los mismos patrones anteriores. La longitud de cadena, expresada como el índice C15jC17, es errática con el aumento de la salinidad.

São apresentadas as informações obtidas no inquérito triatomíneo levado a efeito na região nordeste do Brasil. As características biogeográficas incluem a presença de áreas semi-áridas da caatinga e amplas faixas transicionais com outras feições paisagísticas. Entre estas foram incluídas as da floresta tropical atlântica e as inclusões florestadas mais extensas. No período de 1975 a 1980 foram examinados 15.342 triotomíneos coletados no ambiente domiciliar, visando detectar as presenças de sangue ingerido e de infecção natural por Trypanosoma tipo cruzi. O conteúdo intestinal foi submetido a reações com antisoros para homem, cão, gato, roedor (Kattus), marsupial (Didelphis) e ave (Gallus). Por ordem de freqüência, as espécies encontradas foram Triatoma pseudomaculada (40,6%), Panstrongylus megistus (19,7%), Triatoma brasiliensis e T. sordida (ambos com 14,3%), Rhodnius nasutus (6,1%) e Triatoma infestans (1,1%); além de em algumas outras raras. A presença de sangue foi detectada em 42,4% e a infecção em 3,4% desse total de espécimens examinados. Observou-se elevada mobilidade alimentar, com coeficientes gerais de 54,8% para ave e 30,0% para homem. Em nível específico pôde determinar apreciável grau de antropofilia em P. megistus e, em menor intensidade, em T. brasiliensis. Por sua vez, T. infestans mostrou-se altamente antropófilo. Observou-se apreciável ornitofilia em T. pseudomaculata e T. sordida, com elevada intensidade em R. nasutus. Por outro lado, a presença de sangue humano em espécimens capturados no peridomicílio indicou a ocorrência de freqüente mobilidade espacial, com exceção de T. infestans que não mostrou evidências de abandonar o domicílio. A tendência à domiciliação, além desta, revelou-se apreciável em P. megistus, moderada em T. brasiliensi, T. pseudomaculata, T. sordida e praticamente nula em R. nasutus. A distribuição geográfica confirmou o caráter autóctone de T. brasiliensis, T. pseudomaculata e R. nasutus em relação à caatinga, e do P. megistus em relação às regiões florestais atlânticas e de inclusão. Este último revelou caráter invasivo no que concerne à caatinga, enquanto T. infestans e T. sordida mostraram o mesmo aspecto quanto à região nordeste como um todo. Os resultados permitem concluir que, na transmissão regional epidemiologicamente significante da tripanossomíase americana, desempenha papel relevante o P. megistus, em primeiro lugar, e o T. brasiliensis, em segundo. Dependendo de fatores vários, provavelmente da densidade, poderão atuar secundariamente nesse sentido o T. pseudomaculata e o T. sordida. Quanto à T. infestans, a sua presença, em número reduzido, representa, no momento, risco apenas potencial. O controle rotineiro, mediante a desinsetização domiciliar, deverá fornecer bons resultados no que concerne à interrupção da transmissão. Todavia a reinfestação, pelo menos do peridomicílio, deverá provavelmente continuar. E isso em virtude de focos extradomiciliares que fornecem espécimens com tendência à colonização no ambiente humano. É de se prever que ela se fará a custa do P. megistus nas áreas florestais atlânticas e de inclusão e de T. brasiliensis, T. pseudomaculata e R. nasutus nas áreas da caatinga. A vigilância epidemiológica deverá pois levar em conta esses aspectos e tender a aumentar sua eficiência pela continuidade das pesquisas.This is the presentation of data obtained by a study carried out in the Northeast of Brazil, where the biogeographical characteristics include the 'caatinga' (a semi-arid) savanna and ample transitional strips with other features. Among them are the Atlantic tropical forest and the larger forest inclusions. From 1975 to 1980, a total of 15,342 bugs collected in domiciliar environment were examined to discover the blood feeding habits of and natural infection by Trypanosoma of the cruzi type. Intestinal content was submitted to reactions to antiserums for humans, dogs, cats, rodents (Rattus), opossums (Didelphis), and birds (Gallus). By order of frequency, the species found were: Triatoma pseudomaculata (40.6%). Panstrongylus magistus (19.7%), Triatoma brasiliensis and T. sordida (14.3% each), Rhodnius nasutus (6.1%) and Triatoma infestans (1.1%), and some other rare ones. Blood was detected in 42.4% and the infection rate was 3.4% of the total of the specimens examined. High feeding mobility was observed, and the general blood containing rates were 54.8% for birds and 30.0% for humans. P. megistus showed considerable anthropophily and was followed, at a lower degree, by Triatoma brasiliensis. Ornitophily was detected at high level among T. pseudomaculata and T. sordida, while R. nasutus fed almost exclusively on this host. On the other hand, the presence of human blood in specimens collected in peridomiciliar dwelling places indicates frequent spacial mobility, which occurs after the bugs have had their blood meals. This was quite evident among all the species except T. infestans which thus showed no tedency for displacement from this environment. Domiciliarity was also evident among P. megistus and, to a lower degree, among T. brasiliensis, T. pseudomaculata and T. sordida. However, domiciliarity was not characteristics of R. nasutus. Information on geographical distribution confirms the autochthonous quality of T. brasiliensis, T. pseudomaculata and R. nasutus populations in the 'caatinga'. The same autochthonous feature was evident in the P. megistus with relation to the Atlantic and inclusion forest environments. Nevertheless, it seems that this last triatominae bug becomes invasive in the 'caatinga'; moreover similar patterns were evident for T. infestans and T. sordida in all the Northeast region studied. Results permit the conclusion that, in the regional epidemiological transmission of South American trypanosomiasis, P. megistus play an important role, followed, in this particular aspect, by T. brasiliensis. Depending on several factors, probably colonization density, T. pseudomaculata and T. sordida may come in second in this aspect. For the present, T. infestans low density in the region presents only potential risk. Routine control through the application of domiciliary chemicals will break transmission. However, at least in the peridomiciliary environment, reinfections by P. megistus will continue to occur in the forest regions, and T. brasiliensis, T. pseudomaculada and R. nasutus in the savanna 'caatinga'. Probably this will be due to natural foci that will supply the human environment. Therefore, epidemiological surveillance must to take these several aspects into account and to increase its efficiency by research development.

Com este trabalho, objetivou-se monitorar a fertirrigação com biofertilizante, comparando-a com a fertirrigação química convencional, na cultura do melão variedade 'Orange Flesh', cultivado em ambiente protegido. O experimento foi instalado no Campo Experimental da Universidade de Uberaba, num dos módulos de estufa plástica de 768 m², onde foram aplicados os tratamentos: fertirrigação convencional química e com biofertilizante. Também foram estudadas, dentro dos dois tratamentos, duas freqüências de fertirrigação: diária e semanal. As melhores produtividades foram obtidas com a aplicação diária de fertilizantes, com superioridade para os produtos organominerais, com produção total de 45,5 t ha-1 de frutos, superior estatisticamente às 42,4 t ha-1 obtidas com os produtos minerais. A fertirrigação semanal resultou em produtividades inferiores às decorrentes das aplicações diárias, sendo que os produtos organominerais superaram os químicos nesse tipo de aplicação, em 2,0 t ha-1, em média. Observou-se, também, que os produtos organominerais retardaram, em cerca de 8 d, o ciclo do melão, em comparação com os químicos. Apesar desse alongamento do ciclo da cultura, conclui-se que os produtos organominerais são extremamente eficientes na nutrição do melão, com produtividades similares e até superiores às dos produtos minerais utilizados.The experiment was installed in the Experimental Farm of the Uberaba University, in one of the modules of plastic greenhouse of 768 m². Treatments consisted of two types of fertigation: conventional chemical fertigation and with biofertilizers. Also, two fertigation frequencies were studied for each type: at intervals of one and seven days. The best yields were obtained with the daily fertilizer application, with superiority for the biofertilizers, with production of 45.5 t ha-1 of fruits. This was better than mineral products, which produced 42.4 t ha-1. The weekly fertigation had lower productivities, and in this case, the biofertilizers also surpassed the chemical, on an average by 2.0 t ha-1. It was also observed that the biofertilizers delayed the crop cycle by about 8 days, compared to chemical fertigation. In spite of prolongation of crop cycle, it can be concluded that biofertilizers are efficient in nutrition of melon, with similar or even higher yields in comparison to those obtained by mineral products.
