Capacity of Absorption and Removal of Heavy Metals from Scirpus californicus and Its Potential Use in the Remediation of Polluted Aquatic Environment  [PDF]
Walter Cuadrado, María Custodio, Ciro Espinoza, Carmela Vicua, Marilú Uribe
Open Journal of Marine Science (OJMS) , 2019, DOI: 10.4236/ojms.2019.92006
Abstract: The research aimed to evaluate the absorption and removal capacity of Cu, Pb, Fe and Zn from Scirpus californicus for potential use in the remediation of polluted aquatic environments. Initially, Scirpus californicus plants were conditioned in 1.5 liters of 10 ppm Cu solution at a pH of 2.3 as well as Pb, Fe and Zn. Subsequently, the concentration of heavy metals in the root-rhizome, submerged stem and aerial stem was determined; the solution and pH were also analyzed. The greatest capacity of absorption and accumulation occurred in the root-rhizome reaching values for Cu of 491.84, Pb of 739.43, Zn of 830.71 and Fe of 2624.72 mg/kg dry followed by the submerged stem and low values for the aerial stem. The removal efficiency of Cu from the solution was 52.10%, Pb 53.50%, Fe 48.00% and Zn 50.20%. It is concluded that the contact time has a significant effect on the absorption and removal capacity of the metals under study.
EL BESTIARIO DEL HISTORIADOR: LAS BIOGRAFíAS DE "MONSTRUOS" DE BENJAMíN VICU?A MACKENNA Y LA IDENTIDAD LIBERAL COMO UN BIEN EN DISPUTA
Vicua,Manuel;
Historia (Santiago) , 2008, DOI: 10.4067/S0717-71942008000100007
Abstract: this article identifies and analyzes a heterogeneous body of texts (books, press articles, pamphlets and personal diaries) authored by chilean historian benjamín vicu?a mackenna. these texts form part of a single constellation of meaning characterized by the effort of appropriation of a liberal identity, although they concern different subjects and were intended for diverse readerships. this identity was not defined based on the disputes with the catholic church or by the conservative party. instead identity was defined by taking into account the fight for electoral freedom and the democratizing effects of popular sovereignty. the article explores the works of vicu?a mackenna and various episodes of his life to contextualize the circumstances of the texts analyzed.
Las ciencias naturales colaboran con la teología
Vicua E.,Rafael;
Teología y vida , 2002, DOI: 10.4067/S0049-34492002000100006
Abstract: abstract a common misconception is that science and religion are destined to coexist in a state of permanent conflict. such divisions find sustenance in the extreme positions held by the scientific reductionist who sees in science the answer to all aspects of reality and the creationist who follows a literal, unfaltering interpretation of the holy scriptures. in another corner, there are those who feel that science and religion exist to answer unrelated questions, while others can see the common ground in which these two eternal bastions of our society can unite in a fruitful dialogue. this article emphasises that the pursuit of scientific knowledge represents an irreplaceable companion to theological reflection, a doctrine championed on countless occasions by his holiness john paul ii. the origin of life on earth and the biological evolution of man are discussed as examples of this fecund dialogue between science and religion
La protección de los derechos del individuo en el derecho internacional: Es la selectividad compatible con la universalidad?
Francisco Orrego Vicua
ACDI : Anuario Colombiano de Derecho Internacional , 2009,
Abstract: The international protection of human rights has been based onthe principle of universality that characterizes this concern of the international law, but the intervention of selectivity criteria has led a discrepancy in the results.Several factors have limited the effective protection: there is no clarity as compared to concepts of enforceability and binding instruments, norm of ius cogens and normative hierarchy; infl uence of the political conjuncture and the international relations between States; States delegate in the different international organizations, the fulfi llment of their obligations; States are selective by political contributors; Regional institutions stimulate the selectivity for having included in their decisions, not legal issuesTo face this, international law must restore the original values, on having returned to the origins of the international protection and to the purpose of providing direct access to the individuals before the international institutions that there guarantees both the democracy and the professional impartiality.And the institutional changes that could be justifi ed for theprotection sought to transform into a universal reality.
Las ciencias naturales colaboran con la teología

Teología y vida , 2002,
Abstract: RESUMEN Muchos piensan que ciencia y religión están destinados a convivir en un permanente conflicto. Esta creencia encuentra sustento en posiciones extremas representadas por científicos reduccionistas que pretenden encontrar en la ciencia las respuestas a todos los aspectos de la realidad y a corrientes creacionistas que interpretan literalmente las Sagradas Escrituras. Existen, por otra parte, quienes sostienen que ciencia y religión se ocupan de materias que no interfieren entre sí, mientras que también hay partidarios de que entre ciencia y religión se puede establecer un fructífero diálogo. En este artículo se enfatiza la idea de que la investigación científica representa un insustituible apoyo a la reflexión teológica, tesis sostenida en repetidas oportunidades por S.S. Juan Pablo II. A modo de ejemplo, se discuten las investigaciones sobre el origen de la vida en la tierra y la evolución biológica del hombre como instancias fecundas de diálogo entre ciencia y religión ABSTRACT A common misconception is that science and religion are destined to coexist in a state of permanent conflict.

Abstract: Este trabajo identifica y analiza una conjunto heterogéneo de textos (libros, artículos de prensa, folletos, diarios personales) del historiador Benjamín Vicu a Mackenna, los cuales, si bien aluden a temáticas muy diversas, conforman una constelación de sentido marcada por el esfuerzo de apropiación de la identidad liberal, definida no en función de las disputas ideológicas con la Iglesia Católica y el Partido Conservador, sino con relación a la lucha por la libertad electoral y el ensanchamiento de la base de ejercicio de la soberanía popular, cualquiera fuera el signo político del gobierno en ejercicio. Para ello, indaga en obras de distintos periodos del historiador, así como en variados episodios de su biografía, con el propósito de contextualizar las circunstancias de producción de los textos de interés para el análisis.
