Title A name given to the resource Eficiencia de solubilización de fósforo de aislados nativos guatemaltecos de Pseudomonas fluorescens Creator An entity primarily responsible for making the resource Jose A. Ruiz-Chutan, Julio E. Berdúo-Sandoval, Anibal Sacbajá, Marie Kalousová, Bohdan Lojka, Eloy Fernandez, Jana Žiarovská, Amilcar Sanchez-Perez Description An account of the resource El fósforo (P) es un elemento esencial en la producción agrícola, pero debido a su compleja dinámica en el suelo, solo una pequeña cantidad es aprovechable para las plantas, ya que la mayoría del P se encuentra en formas insolubles, especialmente, en suelos Andisoles de origen volcánico. Los microorganismos con capacidad solubilizadora de fósforo (MSF) son una alternativa para transformar el P a formas solubles y aprovechables por las plantas; además de brindar múltiples beneficios ambientales. Este trabajo identificó y evaluó in vitro, aislados nativos de Pseudomonas fluorescens Mingula, obtenidos de regiones guatemaltecas con suelos Andisoles que limitan la producción agrícola por la alta fijación de P. Se realizaron cultivos in vitro de la bacteria en medio National Botanical Research Institute's phosphate growth (NBRIP), con fosfato tricálcico Ca3(PO4)2 como fuente de P insoluble y se midió el índice de solubilización de fósforo (ISF). Un total de 35 aislados de P. fluorescens fueron identificados y confirmados por PCR específico. El análisis de relaciones genéticas con el marcador AFLP, mostró dos grupos: el grupo A incluyó a los aislados con ISF mayores a 1.75, mientras el grupo B incluyó a aquellos con ISF menor a 1.75. La comparación de ISF entre los aislados y departamentos, demostró diferencia estadísticamente significativa (p < .001), con el aislado Pf_33 como más eficiente. Debido al potencial de solubilización de los aislados nativos del grupo genético A (ISF > 1.75), estos se recomiendan para futuras investigaciones que determinen su respuesta a condiciones de campo y estrategias para el desarrollo de biofertilizantes.

Title A name given to the resource TIPOLOGIA DOS SISTEMAS DE PRODUÇÃO DOS ASSENTAMENTOS ESPONTÂNEOS E INDUZIDOS NO ESTADO DO AMAPÁ Creator An entity primarily responsible for making the resource José Adriano Marini Description An account of the resource O objetivo geral deste estudo foi construir uma escala de medidas para estimar os estágios de modernização da agricultura, tendo como metodologia a forma participativa de levantamento e diálogo de informações. Baseando-se na origem e formação dos assentamentos no estado do Amapá, delimitou-se os mesmos em dois tipo: espontâneos e induzidos. Buscou-se caracterizar os sistemas de produção familiares em tipologias que agrupassem estes sistemas em similaridades e permitissem delinear as práticas que melhor favorecessem o desenvolvimento das propriedades. Através da Metodologia participativa, realizou-se, junto aos agricultores, um diagnóstico rápido e dialogado que posteriormente foi tratado e em seguida devolvido aos mesmos por meio de reuniões de restituição. Foram identificados quatro Tipos distintos de sistemas de produção, sendo o mais desenvolvido aquele que integrava as atividades de produção de farinha de mandioca com outras culturas para consumo e comercialização e a criação de pequenos animais, porém o sistema que mais permitia retornos financeiros anuais aos agricultores familiares foram aqueles cuja produção agrícola era exclusiva para a produção de farinha de mandioca aliada aos recebimentos de benefícios sociais (aposentadorias e bolsas sociais). Este foi observado exclusivamente entre os agricultores de assentamentos espontâneos, onde as práticas agrícolas já vêm sendo propagada entre gerações há mais de 300 anos, e favorecia não apenas à obtenção de altos rendimentos na conversão da mandioca em farinha, mas também a venda por maiores valores da farinha nos mercados devido as suas melhores características organolépticas.

Title A name given to the resource Ancient cynicism as a therapy for the crisis of global capitalism Creator An entity primarily responsible for making the resource José Alberto CUESTA MARTÍNEZ Description An account of the resource Although a temporal distance of more than two thousands of years, Hellenism and contemporary society show analogous “spirits of time” (zeitgeist); with characteristics such as cultural malaise, loss of the old political and social frameworks, cultural syncretism, or recovery of nature and regulatory framework. Hellenistic ethics emerged as therapeutics that would guide the individual in this crisis of the Greek world. In this paper examines the possibility of using the critical tools of the old cynicism, to apply them therapeutically on the global ecological crisis, created by industrial capitalism. The principles of ancient cynicism can be recycled for a project of degrowth society Date A point or period of time associated with an event in the lifecycle of the resource 2016 Subject The topic of the resource Biomimesis, Decrecimiento, Malestar Cultural, cinismo, cosmopolitismo, crisis ecológica, helenismo, parrésia Source A related resource from which the described resource is derived Azafea: Revista de Filosofía Publisher An entity responsible for making the resource available Ediciones Universidad de Salamanca Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Philosophy (General) Relation A related resource <a href="http://revistas.usal.es/index.php/0213-3563/article/view/12951" target="_blank" rel="noreferrer noopener">http://revistas.usal.es/index.php/0213-3563/article/view/12951</a> https://www.socictopen.socict.org/files/original/a28d91cc2a2d74e3122a5d441c6fa136.pdf a2029833d893a65f83d01abe35b488d0 Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

La investigación fue mixta: “Aplicada” en la primera parte, luego “explicativa”, “longitudinal” y finalmente “cuantitativa” y “correlacionada”, de acuerdo a la finalidad de la misma. Los resultados hallados fueron: de los datos estadísticos aportado por los Gobiernos Autónomos Descentralizados (GAD) Municipales de los cantones de la provincia de El Oro, presentados en forma global, los gastos ejecutados fueron mayores a los ingresos obtenidos por la tasa de recolección de basura, lo que generó un subsidio del presupuesto general del estado por 10 031 893,38 USD, es decir, se mantuvo un déficit presupuestario en el manejo de los desechos sólidos en un promedio del 41%, conforme lo demuestra la gráfica No. 5. En conclusión, se sustenta que es admisible bajar el riesgo del impacto ambiental negativo de la provincia, y que su impacto se convierta en positivo para el buen vivir.

Title A name given to the resource Pigmentos fotosintéticos de Stevia rebaudiana Bert en condiciones diferenciales de luz solar y fertilización nitrogenada en invernadero Creator An entity primarily responsible for making the resource José Alejandro Cleves Leguízamo, Carina Cecilia Cordero-Cordero, ALFREDO DE JESUS JARMA-OROZCO Description An account of the resource Contextualización: El área de siembra del cultivo de estevia ha venido creciendo de manera significativa, debido a las nuevas tendencias de consumo de alimentos naturales, bajos en calorías. Los efectos de las altas radiaciones, debidas al cambio climático global, han evidenciado la necesidad de desarrollar nuevos estudios sobre el comportamiento fisiológico de los pigmentos fotosintéticos de las especies agrícolas.    Vacío de conocimiento: El desconocimiento del comportamiento de los cultivos de estevia frente a los cambios actuales y futuros del ambiente (principalmente ante aumentos  de los niveles de radiación solar) hace que los agricultores y productores no obtengan los rendimientos esperados.    Propósito del estudio: El objetivo de este estudio fue analizar el efecto de diferentes niveles de radiación solar y de fertilización nitrogenada,  en condiciones controladas,  en la producción de pigmentos fotosintéticos  de Stevia rebaudiana Bert.    Metodología: El ensayo se estableció mediante un diseño estadístico completamente al azar (DCA), bajo un arreglo factorial 2 x 6, y 16 repeticiones por tratamiento; el factor A correspondió a dos niveles de radiación solar incidente (300 y 1500 μmol de fotones. m-2 s-1 correspondientes al 20 % y 100 % de radiación respectivamente) y el factor B a seis dosis de nitrógeno (0, 60, 120, 180, 240 y 300 kg ha-1). Se evaluó el contenido de clorofilas a, b y total en hojas jóvenes y sanas a los ocho meses después del trasplante.    Resultados y conclusiones: Los resultados evidenciaron que los contenidos de clorofilas a, b y total fueron afectados significativamente por la radiación solar, pero no por los niveles de nitrógeno. En ambos ambientes de radiación, los contenidos de clorofila a fueron superiores a los de clorofila b. En el ambiente de menor radiación solar se presentaron los máximos contenidos de los pigmentos fotosintéticos. En el ambiente de 1500 µmol de fotones m-2 s-1, los contenidos de clorofilas a, b y total fueron menores en las plantas que no se fertilizaron.   Date A point or period of time associated with an event in the lifecycle of the resource 2021 Subject The topic of the resource clorofila a, clorofila b, clorofila total, nitrógeno, radiación solar Identifier An unambiguous reference to the resource within a given context 10.22490/21456453.4528 Source A related resource from which the described resource is derived Revista de Investigación Agraria y Ambiental Publisher An entity responsible for making the resource available UNAD Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Agriculture, Environmental sciences Relation A related resource <a href="https://hemeroteca.unad.edu.co/index.php/riaa/article/view/4528" target="_blank" rel="noreferrer noopener">https://hemeroteca.unad.edu.co/index.php/riaa/article/view/4528</a>
