Removing ions Pb (II) was investigated from aqueous solutions using biomass corn cob chemically modified with a 0,2 M NaOH solution, using a batch system, achieving 40% increase in adsorption capacity compared to similar unmodified (ZM). The corncob modified (MZM) was characterized by infrared spectroscopy Fourier transform (FTIR) determining presence of functional groups such as OH and carboxylic groups which would favor biosorption process, the surface area was determined to be the equal to 2,2 m2 /g. Likewise, adsorption capacity versus time MZM contact biosorbent dose, pH and initial concentration of Pb (II) solution were evaluated. The optimal conditions for the removal of Pb (II) were 4g/L MZM, stirring time 60 minutes and pH equal to 5,0. The kinetic data were fitted to the model of Pseudo Second Order, experimental equilibrium data were better adjusted to the Langmuir model, whic...

Revalorar alimentos andinos de gran valor nutritivo es una tarea pendiente en el país. Es el caso de la arracacha, raíz también llamada “zanahoria andina” es rica en almidón y de fácil digestibilidad. El estudio evaluó el impacto del tiempo de acetilación (0,5-6 horas) del almidón de arracacha (Arracacia xanthorrhiza) con anhídrido acético a 120 °C sobre sus propiedades fisicoquímicas. Se observó que el grado de sustitución (GS) aumentó con el tiempo, alcanzando un valor máximo de 2,91 tras 6 horas. La viscosidad aparente también incrementó, alcanzando 25 483 cP al final del proceso. El índice de absorción de agua fue mayor en la primera hora (25,3 %), permaneciendo estable posteriormente. En contraste, la solubilidad aumentó progresivamente hasta alcanzar un 16,4 % a las 6 horas. El poder de hinchamiento del almidón acetilado superó al crudo, con un pico del 3...

El obispo de Trujillo dejó un testimonio gráfico de su visita pastoral a las provincias serranas del norte del virreinato peruano en el llamado Códice Martínez Compañón (1782-1785). Las partituras contenidas en ese documento son una fuente primaria indispensable para aquellos interesados en las músicas vernáculas del mundo andino. De hecho, algunas tonadas y bailes del Códice son, para muchos, evidencia de una historia de mestizaje cultural y de supervivencia de músicas prehispánicas. Otros añaden que la hibridez estilística de esa música podría interpretarse como un espacio de resistencia o contracultura indígena. En este trabajo se argumenta que las posturas anteriores pecan de miopía y se ofrece un tercer derrotero menos frecuentado. La tesis central es que la música del Códice pudo haberse originado como una expresión de orgullo local o patriota que fue avalada po...

The objective of this research was to evaluate two modified methods to determine sulfur dioxide (SO2). The sampling was carried out in five representative zones of the city of Tingo Maria through the sampling train and Palmes tubes, the analyses were carried out in the environments of the Laboratory of the Biotechnological Research Center of the Amazon at the National Agrarian University of the Jungle, in the District of Rupa Rupa, Department of Huanuco. The results indicate that the method proved to be linear (r2 = 0.996), accurate (CV < 11 %), sensitive (LOD = 0.028 ug or 0.933 ug/m3 and LC = 0.93 ug or 3.100 ug/m3) and robust (P-value > 0.05). According to the results of the method performance, the proposal of method FIF-19029417 was elaborated to determine SO2 by visible spectrophotometry according to NTP - ISO/IEC 1725 (2006). In the determination of SO2 it was observed that, ...

Os produtos defensivos tem sido utilizados em grande escala para garantir a produtividade de diversas culturas. O uso indiscriminado destes produtos tem resultado em impactos negativos ao ambiente, principalmente com resíduos tóxicos na água, solo, ar, plantas e animais. O fipronil é um inseticida que pertence ao grupo dos fenilpirazois utilizado amplamente na cultura de cana-de-açúcar, que por lixiviação ou encorreamento aumenta as possibilidades de atingir o ecosistema aquático. O presente estudo objetivou avaliar o risco ambiental ecotoxicológico a partir da concentração letal 50 durante 96 h (CL 50 96h) para Poecilia reticulata, em ausência e presença de sedimento, valor que foi estimado em 0,08 ± 0,01 mg/L para o primeiro e 0,09 ± 0,01 mg/L para o segundo.

The so-called Genetically Modified Organisms (GMOs) constitute a true revolution of biotechnology. The nutritional improvements at the genetic level represent the main objective for the production of “transgenic foods”. However, despite the benefits of using these techniques derived from research in cellular and molecular biology, this has not prevented taking into account safety issues related, mainly, to the packaging. Therefore, the present work raises some reflections on the new challenges facing the law before these new foods, specifically, in terms of labeling, based on what is established by international instruments and the experience given in developed countries, to finally provide a legislative initiative able to safeguard the fundamental rights of consumers.

This research paper addresses the situation of the Guaná language in Paraguay, one of the indigenous peoples of the Maskoy linguistic family, highlighting the challenges and opportunities for its revitalization through artificial intelligence. Among the main justifications is that the Guaná language faces a serious threat of extinction, with only three elderly native speakers, which requires comprehensive measures for its preservation. The objective of the paper is to analyze the proposal for the integration of artificial intelligence in an educational curriculum for the revitalization of the Guaná language. The methodology was based on a literature review and comparative case studies of language revitalization in similar contexts. As for the results, effective strategies for language documentation and teaching were identified, including the use of digital tools and the creation of ...
