Extracción de polifenoles: una comparación a partir de cáscara de cacao húmeda vs cáscara de cacao secada
Authors: Muvdi Nova Carlos Jesús , López Giraldo Luis Javier , Cáceres-Roa Sergio Alejandro
Published: July 2023

La cáscara de cacao es un residuo agrícola que puede ser valorizado gracias a la presencia de compuestos bioactivos tales como los polifenoles; la importancia de éstos últimos radica en que se ha probado que tienen un efecto positivo para la salud por sus propiedades antioxidantes y antirradicalarias. Para el procesamiento, la cáscara de cacao es normalmente llevada a una etapa de secado antes de la extracción; sin embargo, a escala industrial la implementación de esta etapa podría resultar costosa (costos de inversión y funcionamiento). Por lo cual, es útil determinar si es posible realizar el proceso de extracción sin afectar esta etapa. El presente trabajo evaluó la extracción de polifenoles utilizando cáscara de cacao húmeda, analizando el efecto que tienen diferentes condiciones de extracción (relación etanol:agua, relación soluto:solvente, temperatura de extracción) sobre el rendimiento y la cinética de la misma. Los resultados mostraron que, bajo condiciones óptimas de extracción en húmedo, el contenido de polifenoles totales estuvo alrededor del 85 % de lo obtenido en seco (54.75±1.49 mgEAG/g, para cáscara seca) y la capacidad antioxidante disminuyó alrededor de un 10 % con respecto a la cáscara secada (1002.59±110.21 y 417.12±11.35 mgET/g, por ORAC y DPPH, respectivamente). El tiempo máximo del proceso fue de 60 min y el modelo que mejor describió la cinética de extracción fue el Peleg Modificado (R2 = 0.9598). Esto evidencia la posibilidad de extraer una cantidad considerable de polifenoles con respecto a lo extraído en seco, aspecto importante al considerar su aplicación a mayor escala.

El objetivo de este estudio fue evaluar la sustitución parcial de la harina de trigo por harina de quinua de Cundinamarca Colombia, su efecto sobre las propiedades tecnofuncionales, fisicoquímicas, texturales y sensoriales de las mezclas de harinas y la elaboración de las galletas con la muestra control. Se evalúan tres formulaciones con diferentes niveles de inclusión de harina de quinua, mezcla 1 (T0):control, mezcla 2 (T1): 10% y mezcla 3 (T2): 20%. La incorporación de harina de quinua afecta las propiedades tecnofuncionales al disminuir la capacidad de absorción de agua (CAA) para T1 y T2, mientras la capacidad de absorción de aceite (CAAc) aumenta para T3, el contenido de humedad presentó diferencias significativas para la muestra control T0 . En las galletas se encontró diferencias en el contenido de humedad entre los tratamientos T0, T1 frente a T2, mientras en la actividad de agua se evidencia diferencias significativas para todos los tratamientos, en la relación de extensión no se evidencia diferencias, respecto a textura se encuentra que afecta la dureza de todos los tratamientos a excepción de fracturabilidad que no afectó a los productos. En la parte superior de las galletas se encuentra diferencias significativas de los parámetros L* (luminosidad) y a*(de verde a rojo) en los tratamientos T1 y T2, al obtener una galleta de color dorado, en la parte inferior se encontró diferencias en todos los tratamientos. Sin embargo, el producto aceptado fue T1 con 10% de sustitución de harina de quinua. Al analizar el contenido nutricional, se encuentra un alto contenido proteico en comparación con otros productos similares desarrollados en otras investigaciones y los resultados microbiológicos cumplen de manera satisfactoria con la normatividad vigente.
Effect of the maturity stage, genotype, and geographical location on the physicochemical characteristics of the cocoa bean during fermentation
Authors: López-Hernández Martha del Pilar , Melo-Martinez Sandra Esperanza , Criollo-Núñez Jenifer
Published: July 2023

An essential aspect of competing in the world market is the quality of the cocoa bean, which is influenced by different factors ranging from genetics to post-harvest processes. The aim of this research was to determine the effect of the maturity stage (2, 3, and 4), genotype (CCN51, ICS95, and TSH565), and geographical location (Algeciras and Garzón, Colombia) of cocoa on the pH and titratable acidity of the pulp and bean, and the fermentation index of the bean during days 0, 3 and 7 of fermentation. The response variables were analyzed through an analysis of variance (ANOVA), and multiple comparisons (pairwise) were made using Tukey's test with a significance level of α = 0.05. Additionally, a longitudinal analysis was carried out as there are measurements over time, and autocorrelation of individuals over time can occur, allowing contrasting the results through another analysis. The results showed that the factor with the strongest influence on the physicochemical characteristics evaluated was the genotype, affecting the bean and pulp pH and the fermentation index. Likewise, it was possible to show that, of the three genotypes evaluated, CCN51 stood out for presenting less bean acidity and higher bean pH and fermentation index. The genotype is the factor with the strongest effect during cocoa fermentation. This solves bean quality heterogeneity, the main international marketing problem.

Published: July 2023

Cocoa agrosystems can provide available habitats for wildlife species, due to the structure and diversity of established shade trees in plantations. The objective of this research is to calculate the index of importance and forest value of shade trees used in cocoa agrosystems in the region of Comalcalco, Tabasco, Mexico. Field sampling was carried out to collect data on breast height diameter, canopy diameter and canopy height, these variables were used to estimate the importance value index and the forest value index. The trees with the best indexes of importance and forest value are Erythrina americana (IVI = 62.34 and FVI = 50.94), Bursera simaruba (IVI = 62.53 and FVI = 66.99) and Samanea saman (IVI = 56, 85 and FVI = 42.93). The dynamic of shade trees in cocoa agrosystems is important since it could be used as an input variable to evaluate and predict, through an ecological niche model, the quality of the available habitat for the conservation of wildlife such as birds, reptiles and arboreal mammals.

Debido al conflicto armado y el tráfico de drogas, la Sociedad Colombiana debe afrontar el serio problema de los cultivos ilícitos. El número de hectáreas de éstos se ha incrementado dramáticamente en el último año, cuya erradicación debe ser manual. Dado que la fuerza pública es la responsable de esta actividad complicada y riesgosa es importante proveerla de herramientas que faciliten su tarea. Este trabajo presenta una aplicación denominada SIREG versión móvil. Esta es parte de un concepto más amplio de un sistema software de administración de información de la erradicación de cultivos ilícitos denominada SIREG. Este trabajo se enfoca en la versión móvil cuyo propósito es el permitir capturar y enviar información relevante del proceso de erradicación, la cual es normalmente recolectada de manera manual y transmitida por voz conllevando errores en los reportes de dicha información. Para esto, se identificaron los principales componentes del proceso tales como características de los cultivos, información de las patrullas ejecutoras, registro fotográfico e información georreferenciada de las áreas erradicadas. Estos componentes fueron utilizados para definir la funcionalidad de la aplicación a través de módulos asociados a cada componente. La implementación se realizó en un Trimble TDC100 el cual es un dispositivo Android que tiene características técnicas adecuadas para condiciones difíciles en terreno. Adicionalmente a la implementación de la funcionalidad de la aplicación, el dispositivo presento un error de georreferenciación del 0.3% en espacios abiertos. La aplicación permite reportar la información de manera transparente, permitiendo tener trazabilidad del proceso y monitoreo, siendo esto de gran importancia para los tomadores de decisiones como lo son personal militar de alto rango o autoridades. Adicionalmente, esta información digitalizada permitiría tener una información confiable de áreas que pueden estar afectadas por los cultivos ilícitos como lo son las zonas expuestas a deforestación o áreas naturales protegidas.

Authors: Sujathan P. K. , M.G Prasad
Published: July 2023

This paper analyses the impact and implications of the traditional multiseed farming technique (MSFT) among tribes on their food security in the Attappady block of Kerala State. Using the definition of food security by the United States Department of Agriculture, the study corroborated that the problem of ‘Very Low Food Security’ is persistent among such tribes not engaged in MSFT. The paper makes a strong pitch for the government to overhaul the extant schemes and play the role of a facilitator to enable all tribes to engage in MSFT which is a panacea towards accomplishing food security among them.
O Coro e o Povo na Oresteia, de Ésquilo: o coro de Agamêmnon
Authors: Irigaray Tiago
Published: July 2023

O coro de Agamêmnon, constituído por anciãos, homens livres que circulam livremente no espaço público e estão às voltas com os acontecimentos políticos de Argos, aproxima-se do modo de viver dos cidadãos atenienses. O coro inclusive profere ferrenhas críticas a Agamêmnon, embora de forma velada. Detentor de um destino coletivo e de uma ligação indireta com os deuses e também agindo como interlocutor do presente democrático ateniense com seu glorioso passado mítico aristocrático, há uma inegável aproximação do coro com o povo. O povo, contudo, não é uma coletividade coesa como o coro, é muito diverso e a relação entre o coro e o povo é indireta e parcial. Dito isso, Agamêmnon é uma das tragédias nas quais o coro mais se aproxima do povo ateniense em suas críticas, seu zelo pela cidade, sua insubordinação contra tiranos, e demais ações.
Medeias Propercianas: uma recolha
Authors: Panisset Letícia Rodrigues Ferreira , Martins Paulo
Published: July 2023

A Mitografia, isto é, o escrever sobre os mitos, aparenta ter sido escrita comum entre os antigos. Esse gênero, no entanto, parece apresentar duas vertentes: uma que coleta e outra que interpreta as narrativas míticas. No primeiro grupo, destacam-se autores como Higino e Pseudo-Apolodoro. Por outro lado, entre os poetas, também se utilizou dessas narrativas, no que se destaca a poesia de Propércio, poeta augustano. Em sua produção, pode-se salientar a presença das histórias de Medeia, que são, segundo a tradição, várias e variadas, desde sua vida na Cólquida – passando pela tragédia em Corinto – até a fuga para Atenas. Na elegia properciana, por sua vez, vê-se o poeta utilizar os diferentes episódios desse mito na construção de seu discurso.
Uma Medeia afro-brasileira “rainha, preta e orixá”: recepção da antiguidade na peça Além do Rio de Agostinho Olavo
Authors: Dagios Mateus
Published: July 2023

Partindo do objetivo de rastrear recepções do mito grego que não as privilegiadas pelo eurocentrismo, o artigo desenvolve uma investigação sobre a recepção da antiguidade no texto Além do Rio (1961) de Agostinho Olavo. A peça é uma recriação de Medeia de Eurípides a partir da proposta do Teatro Experimental do Negro (TEN), grupo fundado por intelectuais negros como Abdias do Nascimento que desejavam propor uma discussão sobre o lugar do negro na sociedade brasileira. O artigo analisa como temas do mito grego de Medeia foram revisitados para problematizar situações de tensão racial, mostrando a trajetória da heroína Jinga, que se transforma em Medeia, do apagamento à redescoberta das próprias raízes africanas. A peça problematiza temas da identidade e da exclusão dos negros na sociedade brasileira. O mito de Medeia e seu trágico desfecho é um ponto de reflexão para abordar temas como a ilusão da democracia racial, o problema da integração social, o preconceito e o apagamento da escravidão como experiência originária das tensões sociais no país.

Authors:   Korea International Law Review, Jang Hyewon
Published: July 2023

The purpose of this study is to examine the responsibility for marine discharge of radioactive contaminated water under international law, and to examine the significance of marine discharge of contaminated water from Fukushima nuclear power plant, which is expected in 2023. The contents and legal structure of the actual laws and regulations. To this end, we analyzed marine environmental pollution and under the contents and legal structure of the actual laws and regulations to clarify the phenomena and definitions. We tried to examine examples of practical applications based on the Fukushima nuclear accident. The Fukushima nuclear accident is not just a nuclear accident, but shows the dangers of a society when relying on nuclear energy. This discussion could be an approach to environmental issues beyond mankind marine pollution and its impact.
Therefore, in this paper, analysis was conducted focusing on international agreements for research. Conventions that have become the center of research are the 1972 London Convention, the 1996 London Protocol, two international conventions.
This study is based on the analysis of marine environmental pollution and nuclear power plant accident liability analysis revealed through the previous discussion, the problem of ocean discharge of contaminated water from the Fukushima nuclear power plant, scheduled for 2023, was considered. In particular, after reviewing the overview including the background of the discharge of polluted water to the sea, I reviewed the current status of countermeasures for the discharge of polluted water and the related future tasks. In addition, analyzed the pros and cons of the discharge of polluted water according to the rationale. Also, examined Contaminated marine emissions discussed at the Conference of Parties to the London Convention and Protocol and significance of environmental impact assessment that can act as a precautionary measure such as environmental assessment of the release of radioactive contaminated water into the ocean.
In conclusion, it should be possible to emphasize the meaning of information disclosure and cooperation as a national activity and development of guidelines for the London Convention and Protocol to effectively regulate the release of radioactive contaminated water to the sea. In addition, in accordance with diverse attempts under international law to prevent this in advance, it is necessary to take a lead towards Japan’s release of radioactive contaminated water through cooperative and systematic research between countries in the Pacific.

Authors: Link Caroline , D`Haese Thomas Markus , Frigieri Gustavo , Brasil Sérgio , Vellosa José Carlos Rebuglio , Welling Leonardo
Published: July 2023

Background:

Cerebral edema (CE) and intracranial hypertension (IHT) are complications of numerous neurological pathologies. However, the study of CE and noninvasive methods to predict IHT remains rudimentary. This study aims to identify in traumatic brain injury (TBI) patients the relationship between the volume of the lateral ventricles and the parameters of the noninvasive intracranial pressure waveform (nICPW).

Methods:

This is an analytical, descriptive, and cross-sectional study with nonsurgical TBI patients. The monitoring of nICPW was performed with a mechanical strain gauge, and the volumetry of the lateral ventricles was calculated using the free 3D Slicer software, both during the acute phase of the injury. The linear model of fixed and random mixed effects with Gamma was used to calculate the influence of nICPW parameters (P2/P1 and time-to-peak [TTP]) values on volumetry.

Results:

Considering only the fixed effects of the sample, there was P = 0.727 (95% CI [−0.653; 0.364]) for the relationship between P2/P1 and volumetry and 0.727 (95% CI [−1.657; 1.305]) for TTP and volumetry. Considering the fixed and random effects, there was P = 8.5e-10 (95% CI [−0.759; 0.355]) for the relationship between P2/P1 and volumetry and 8.5e-10 (95% CI [−2.001; 0.274]) for TTP and volumetry.

Conclusion:

The present study with TBI patients found association between nICPW parameters and the volume of the lateral ventricles in the 1st days after injury.

Published: July 2023

Die digitale Entwicklung und die stärkere Verbreitung von sozialen Medien mit u. a. speziellen wissenschaftlichen Kanälen führt zu einem Wandel der Erwartungshaltung der Studierenden an das Thema Lehre. Gleichzeitig wandeln sich die Anforderungen an die Absolventen hin zu einem fachübergreifenden Wissen. Ziel des umzusetzenden Lernprojektes ist es, die bisherigen Einzelformate mit der Anwendung einer Art Planspiels zu kombinieren, um auf diese Weise die Interaktion sowie die Präsenzteilnahme zu stärken. Dies ermöglicht, die theoretischen Erkenntnisse direkt mit praktischen Komponenten zu koppeln und somit energietechnische Fragstellungen aus verschiedenen Standpunkten zu beleuchten. Durch Elemente der Gamification wird hierbei für die Studierenden eine motivierende Lernsituation hergestellt, welche eine hohe Interaktion fördert. Die erste Umsetzung erfolgt im Rahmen der Vorlesung „Analyseverfahren von komplexen Energiesystemen“, indem ein Gebäudemodell erstellt und die Heizungsanlage ausgelegt werden soll.

Published: July 2023

A variety of rotary molecular motors powered by light, chemical energy or tunnelling electrons have been synthesized and their operation in solution, in gels or on surfaces has been demonstrated. However, the single-molecule mechanics of such machines remain scarcely studied and very little data regarding their quantified performances have been disclosed. Here, we report on the synthesis of a series of molecules incorporating a five-arm rotor subunit and the direct quantitative measurement of the work generated by its rotation around the central ruthenium atom. We have used single-molecule force spectroscopy (SMFS) to detect the autonomous oscillations. We demonstrate that a mechanical load does not prevent rotation and show that the chemical nature of the arms influences the energy barrier, causing differences in the work that the motor can generate. Our results illustrate that SMFS, which is now widely used to probe processes at the scale of a few tens of nanometers in biomacromolecules, can detect motions around a single atom in a tiny synthetic molecule.

IOT BASED SOIL MOISTURE MONITORING AND SOIL MOISTURE PREDICTION USING LINEAR REGRESSION (CASE STUDY OF VINCA PLANTS)
Authors: Iriyanta Kuindra , Putranto Bambang Purnomosidi Dwi , Andriyani Widyastuti
Published: July 2023

Soil moisture is something that becomes important. Indonesia as an agricultural country, most of the population has a profession as a farmer. In agriculture, one of the important parts is the water composition in the soil or soil moisture. One attempt to maintain soil moisture is to provide sufficient water intake to the soil. However, in practice, it is sometimes complicated for farmers to do proper irrigation of their agricultural land. This humidity condition will ultimately determine the success of vinca plant cultivators. The accuracy of giving water both in terms of time management and volume are two things which are an important focus of vinca crop growing. This system is designed using a humidity sensor which is used to measure the moisture composition contained in the soil, and an air temperature sensor. The NodeMCU ESP2866 microcontroller acts as a link between Google spreadsheet sensors. NodeMCU ESP2866 will send humidity and temperature sensor reading data to Google spreadsheets using a RESTfull API which can connect one application to another. The sensor data is then saved to Google spreadsheet and processed using the linear regression method. The processing results will be displayed on the Google Data Studio dashboard. The output of this process is to provide information about soil moisture conditions, notification of soil moisture conditions if it is too dry or damp, thus the prevention of the death of vinca plants can be carried out. The benefit for users is that they can carry out periodic and real-time monitoring by simply using the Telegram instant messaging application, which is expected to reduce the risk of plant death due to drought or excessive watering

"¡No es sequía, es saqueo!" Propaganda y movimiento social durante la crisis hídrica en Monterrey, México, desde el sentido común de Gramsci.
Authors: Martinez-Canales Luis Alejandro
Published: July 2023

Se propone el sentido común (senso comune) de Antonio Gramsci para aproximarse a las «certezas» en las informaciones sobre la emergencia hídrica en Monterrey, México, durante 2022. El senso comune  se presenta como un cúmulo de conocimientos que proporciona una certidumbre paradójica frente a sucesos que descomponen la rutina urbana. El cuestionamiento guía es si la coyuntura noticiosa del déficit de agua daría pie, en el largo plazo, a un movimiento social que suponga un sentido común diferente al gubernamental hegemónico.

Se analiza la información aparecida principalmente en medios masivos, ofrecida por autoridades, y la originada en redes sociales y actos públicos del “Frente de Organizaciones Ciudadanas por la Defensa del Agua NL”. Se describe el escenario de incertidumbre metropolitano como una circunstancia que acogería colectivos de mayor convocatoria para fraguar un pensamiento y acciones frente a fenómenos que como el desabasto de agua, ponen en riesgo la gobernabilidad de la población.

El texto abreva en fuentes documentales y literatura especializada en el tema y caracteriza a la población en condiciones de refugio en nuestro país.
La otra resistencia cultural: el gusto como constructor de identidad territorial. Los tamales en la ZMM.
Authors: García Alejandro
Published: July 2023

En este trabajo se realiza un breve análisis desde la antropología de la alimentación acerca de una forma de resistencia cultural de un patrimonio intangible, la permanencia de los tamales en nuestra dieta a pesar de las hibridaciones producto de la invasión europea hace más de 500 años así como de otros fenómenos que han influido en nuestra historia culinaria y cultural como país.
Se intenta exponer la forma en la que un alimento detona la configuración de ciertas relaciones interpersonales y espaciales y ocupa por tanto un lugar de fundamental importancia en el conjunto de expresiones de las culturas y sus cosmovisiones. Es fundamental de sacar la importancia de estas herencias que están internalizadas y que van con nosotros aún al sitio más remoto, configuraciones expresivas poco abordadas desde las humanidades y que representan otra forma esencial de ser y habitar en nuestro país y en el caso concreto del noreste mexicano.
Ruling Ideology and Discourse in Kim Jong-un's Regime: A Critical Discourse Analysis
Authors:   The Korean Association Of Area Studies, Jung Wonhee
Published: July 2023

This study aims to examine the ruling ideology of Kim Jong-un in North Korea, specifically focusing on the element of “manipulation” within his ruling discourse. To achieve this goal, the study employs Critical Discourse Analysis (CDA), a theoretical trend that highlights the importance of language use in shaping social reality. The study operates on the premise that the North Korean regime is characterized by totalitarianism, with power centralized around Supreme Leader Kim Jong-un. As a result, the governing ideology is produced and distributed uniformly through propaganda.
The analysis concentrates on the ruling discourse during the Kim Jong-un period, and uses editorials and articles published in the Rodong Sinmun from January 2021 to April 2023 as primary data sources. The content of these articles is classified into macroscopic and microscopic aspects, with an emphasis on identifying the expression methods and manipulation techniques used to control public thinking and attitudes.
The results of the discourse analysis reveal that the ruling ideology during the Kim Jong-un period in North Korea is characterized by leader absolutism, collectivism centered on the leader, patriotism, and a utopian vision of equality, welfare, and human rights. However, with the faster spread of marketization, individualism and capitalist thinking have become prevalent in North Korea, making it challenging to control the public's thoughts with outdated governance discourse.
The ruling discourse during the Kim Jong-un period elevates the people to a higher position while imposing more political, economic, and social duties and roles to induce loyalty. The development of this discourse appears to be a phenomenon that emerged as part of a system stabilization strategy, rather than a new change in the North Korean system. Ultimately, the ruling discourse during the Kim Jong-un period is a manipulated message of power that controls the thoughts of the people, legitimizes Kim Jong-un's authority and policies, and contributes to the maintenance and stability of the system.

In architecture and design, new materials can be used to create more durable, sustainable, and aesthetically pleasing products that are lighter and stronger. Through biomimetics, this study analyzed 4 tropical fruit structures - orange, passion fruit, cocoa and pomegranate - to generate a new structure with damping and energy dissipation properties with the aid of scanning electron microscopy (SEM), micro-computed tomography (Micro-CT) and three-dimensional computerized reconstruction. As a result a bio-inspired structure was developed based on the cell wall arrangements found in the mesocarp (albedo) of the orange - Citrus sinensis. Through this developed structure it was possible to make computational tests and its prototyping in resin through digital fabrication. Thus, the development of bio-inspired materials for better impact absorption and damping is important because it can help improve the safety and effectiveness of a wide variety of products, from sports equipment to medical equipment, in addition to contributing to sustainability and energy efficiency, points of great interest for various areas of knowledge and contribution to the exploration of new materials.

Throughout the world, there is a growing interest in the proper use and consumption of sustainable raw materials that are based on the recycling and reuse of petroleum-derived polymers and other recycled materials, such as sheets from collaminates. These "sustainable alternatives" appear to be an attractive solution to environmental problems, however it is important to consider the potential environmental and public health impacts that may result from their use. Therefore, the objective of our research project is to analyze the VOC emissions of "sustainable" polymeric materials such boards and colaminateds. To this end, a prototype chamber for measuring organic compounds has been designed and manufactured by coupling a series of sensors for VOCs. The results have shown the presence of gases such as CO, NO2, NH3 and particulate matter, some of which are above the permitted limits of human exposure, concluding that the emissions of some VOCs may represent a potential risk for both environmental and human health. It is essential to continue researching to find sustainable alternatives that do not compromise the health and well-being of people and the environment.
