Las Aboliciones de la Esclavitud en Iberoamérica: El Caso Peruano (1812-1854)
Authors: De Vinatea María Julia 
Published: August 2021

La globalidad del tema de las aboliciones de la esclavitud en Iberoamérica y el largoperiodo que las embarca hacen menester la metodología comparativa. En efecto, laerosión del sistema esclavista arrancó en el espacio iberoamericano a principios delsiglo con Santo Domingo, en 1801, para acabar con la abolición en Cuba en 1886,“joya de las Antillas” del Imperio Español. Otro fuerte del método comparativo esel de aprehender toda la complejidad del espacio ibérico que no sólo correspondea un territorio dado, sino a una cosmovisión dentro de una historia colonial comúncompartida con España. Este método permite plantearnos este espacio tal comolos contemporáneos del siglo XIX se lo imaginaban, es decir, en una continuidadcultural y lingüística heredadas de la colonia y, al mismo tiempo, en una ruptura deafirmación y de consolidación de la construcción nacional.Asimismo, no se ha repetido lo suficiente, pero la Iberoamérica del siglo XIX era yaun espacio mundializado donde transitaban tanto mercancías, extranjeros, esclavos,traducciones de libros como Uncle Tom’s Cabin (EE.UU.: 1851), así como ideasrevolucionarias europeas y propias de América, como por ejemplo: la revoluciónen Haití. Por otra parte, el tema abolicionista es sumamente complejo y global. Para empezar, la palabra apareció de manera tardía en el vocabulario periodístico inglés, a principios del siglo XIX, es decir, posteriormente a la abolición decretada por la Convención francesa y la revolución haitiana. Además, hay el peligro de que se lleve el tema de manera muy restrictiva y se haga caso omiso de la vivencia y las luchas de los propios esclavos. Cierto es que las voces esclavas resultan escasas para el historiador, puesto que la lógica de la dominación las ha silenciado durante varios siglos: ¿hasta qué punto las violencias del siglo XIX en Iberoamérica alientan la intricada modernización del pensar? ¿Cuál es el grado de relación entre el discurso caudillista y el establecimiento de medidas abolicionistas?De ahí, la urgencia de aplicar un método histórico a la altura de la complejidadde las temáticas, para establecer puentes, relacionar o oponer países y conceptos,entrecruzar y dar cuenta de la hibridación iberoamericana. En efecto, salta casi a losojos la interacción de nociones como: “independencia”, “libertad”, “imperio”, “tratanegrera”, “esclavitud”, “negros, pardos y libertos”, “abolición gradual e inmediata”,etc., estallidos de una concepción del mundo en plena efervescencia, reordenacióny transición.

Published: August 2021

En el presente artículo se desarrolla un modelo matemático para la planeación y el control del inventario de glóbulos rojos en el banco de sangre de un centro hospitalario de nivel III ubicado en la ciudad de Santiago de Cali, este modelo es un soporte para la toma de decisiones, que permite brindar un nivel adecuado de servicio a los usuarios, reduciendo los costos de operación incurridos en el vencimiento de las unidades sanguíneas y en la adquisición a proveedores externos, contribuyendo a solucionar la problemática presente en el Valle del Cauca y algunas regiones de Colombia, donde los bancos de sangre se encuentran desabastecidos de unidades sanguíneas. Inicialmente se caracteriza el comportamiento de la demanda de los glóbulos rojos; posteriormente, se realiza la construcción del modelo matemático, basado en programación lineal por metas donde se utilizan variables aleatorias para considerar la caducidad y sustitución por compatibilidad de las unidades sanguíneas y se da un tratamiento de restricciones flexibles a los objetivos, donde cada uno de estos tiene una penalización para agotados, obsoletos y adquisiciones externas de unidades sanguíneas. Se logra correr el modelo de 8087 variables a través de modelado algebraico AMPL, obteniendo resultados específicos para cada grupo sanguíneo. La operatividad y resultados del modelo fueron verificados con alto grado de confiabilidada través de la simulación discreta donde se recrearon varios escenarios. En conclusión, este modelo se constituye como una herramienta formal y estructurada para la planeación y control de la cadena de abastecimiento de sangre de otros centros hospitalarios.

El presente artículo tiene por objetivo desarrollar un sistema de control de calidad de bebidas embotelladas para la em-presa Cartavio Rum Company mediante el software Visual Studio 2017, empleando el algoritmo transformado de houghy canny para los bordes y aplicación de filtros morfológicos (erode). Este sistema consta de una banda transportadoraque genera el movimiento de las botellas, hasta ser detectadas por la cámara, la cual obtiene las imágenes que son pro-cesadas. Para ello se tiene un sistema para el ingreso de las botellas hacia la faja transportadora que serán llevadas hasta el lugar de captura de las imágenes realizada mediante un software que se encarga de identificar del nivel de llenado del producto, evaluar la alineación y el correcto color de las etiquetas de la botella, también verificar el control de sedimentos o pequeños cuerpos extraños en el contenido de las botellas, para luego realizar el pre procesamiento de las mismas. Al finalizar el pre-procesamiento y determinar las características finales del producto mediante parámetros preestablecidos en bebidas embotelladas de ron, mediante el uso de visión artificial, las botellas que pasen el control continúan hacia un proceso de ubicación en las cajas donde serán despachadas y aquellas que no cumplen son rechazadas y reprocesadas. Se realizaron diversas pruebas que concluyen que el sistema de visión artificial muestra una eficiencia del 95% comparado al de la inspección visual del ojo humano con 55%, corroborando la efectividad de la visión artificial en el proceso de calidad en la empresa.

Published: August 2021

El presente artículo muestra la estructuración y método de una herramienta de medición y recorrido del trabajo realizado en la bodega de reactivos y la bodega de muestras en custodia de una empresa de Oil y Gas en Colombia. Esta herramienta tiene dos propósitos: el primero, es el de describir las tareas realizadas y el segundo, proporcionar un esquema para el desarrollo y mejoramiento de los procesos en el Centro de recepción de muestras de un Centro de Investigación y desarrollo del sector de Oil y Gas, en adelante CEMIM. La medición del trabajo es un método de investigación basado en la aplicación de diversas técnicas para determinar las actividades y el contenido de un trabajo definido, fijando el tiempo que tarda un trabajador calificado en realizar la tarea de acuerdo con un rendimiento estandarizado preestablecido. Con base en lo anterior, se realizó un estudio del trabajo en las bodegas del CEMIM de acuerdo con el número de estanterías, y el recorrido realizado en estas. Los resultados muestran que, al considerar explícitamente los patrones de recorrido realizados por el operario, el análisis de la herramienta estructurada proporciona ventajas relacionadas con la descripción de las tareas y el desarrollo de métodos para el mejoramiento de los procesos.
Writing from the Self: Reflecting on the Role of Creative Writing in the Academic Writing Classroom
Authors: Peñaloza Anna Carolina , Salamanca Laura Camila 
Published: August 2021

As academic writing teachers, we are often faced with the challenge of teaching writing as a system or emancipating from its structures. In this reflective paper, we begin by examining our own experiences with writing for academic and creative purposes using co/autoethnography as a method of self-reflection. In addition, we invited three modern language students at a public university in Tunja, Colombia to share their reflections about their writing processes and the role creative writing could play in the academic writing classroom. Our reflections were a first step in rethinking our classroom from a critical sociocultural model, which revealed that students’ individual writing processes, motivation, feedback, and creative writing could help boost students’ self-confidence when writing for academic purposes.
Decolonial thinking as an alternative to “reverse racism” in soccer
Authors: Nogueira Otávio , Steffen João Alberto , Ferreira da Silva Gilberto 
Published: August 2021

This article addresses the issue of reverse racism in soccer, considered as another subjugation mechanism of the elite of white people, and the criticism of this prejudice. The main objective is to propose an alternative “other” to fight “reverse racism” in soccer, beyond academic criticism. This is a descriptive and bibliographic study, with reflections based on theoretical contributions of thinkers, mainly Latin American. As an alternative “other”, an intercultural project is proposed for the discipline of soccer in Physical Education, with emphasis on decolonial thinking, both in college and in school. It is understood that, in order to respond to the competency dimensions required for an alternative “other”, the physical education teacher must know the theoretical body that supports his field of knowledge and its connection with other areas, as well as the popular knowledge as part of thinking and doing science. We bet on the physical education professional to break the dichotomy where the place for the physical is outside the classroom and the place for the intellect is inside, and to rethink school sports as a social practice of collective participation.
Mg zonation and heterogeneity in low-Mg calcite microcrystals of a depositional chalk
Authors: Rinderknecht Chanse J. , Hasiuk Franek J. , Oborny Stephan C. 
Published: August 2021

ABSTRACTDiagenetic low-magnesium calcite (LMC) microcrystals constitute the framework that hosts most micropores in limestone reservoirs and therefore create the storage capacity for hydrocarbons, water, and anthropogenic CO2. Limestones dominated by LMC microcrystals are also commonly used for paleoclimate reconstructions and chemostratigraphic correlations. LMC microcrystals are well known to exhibit a range of textures (e.g., granular, fitted, clustered), but there exists uncertainty with regard to how these textures form. One hypothesis is that during crystal growth, Mg is incorporated into diagenetic overgrowths (cement), where the chemical zonation and microtexture may reflect diagenetic processes. To evaluate small-scale geochemical zonation in LMC microcrystals, this study uses scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) to measure the Mg/Ca ratio across the interiors of LMC granular microcrystals from a Late Cretaceous marine chalk from the Tor Fm. (Norwegian North Sea).Mg/Ca zonation was identified in all LMC microcrystals with a diameter &gt; 5 μm. Generally, the cores of large crystals have lower Mg/Ca (≈ 5.9 mmol/mol) and the rims have elevated Mg/Ca (≈ 13 mmol/mol). Smaller microcrystals (&lt; 5 μm) show no resolvable zonation, but do exhibit a wide range in Mg/Ca content from 2.9 to 32.2 mmol/mol. Measured Mg/Ca values are arbitrarily divided into three populations: low Mg (average ≈ 5.9 mmol/mol), intermediate Mg (average ≈ 13.3 mmol/mol), and high Mg (average ≈ 20 mmol/mol). The observed zonation and Mg enrichment within LMC microcrystals is interpreted to reflect depositional as well as multiple diagenetic signals, such as constructive precipitation through recrystallization and pore-filling cementation.Although chalk from the Tor Fm. is dominated by granular euhedral LMC microcrystals, using SEM-EDS to find Mg/Ca heterogeneity in other LMC microcrystal textures may provide insight into the diagenetic processes that create textural variations in micropore-dominated limestones. The Mg data also more broadly suggest that there is useful, measurable diagenetic information in material that is otherwise considered homogeneous. Distinguishing between possible primary compositions and secondary cementation has implications for studies that rely on the primary chemistry of fine-grained carbonate deposits (e.g., micrite), such as paleoclimatology, Mg paleothermometry, and chemostratigraphy.

Yogurt was a functional drink that was high in nutritional value but had a relatively short shelf life. Roselle extract had a high content of bioactive compounds, namely anthocyanin, polypHenol, and vitamin C. The integration of yogurt with roselle extract was expected to improve product performance both from the properties of health and sensory. This study aimed to determine the effect of roselle extract addition and fermentation time on the characteristics of roselle-based yogurt products. The research method used was an experimental method with a completely randomized design with Duncan's further test with treatments (1) the addition of rosella extract consisted of 3 levels, namely 0.5, 1.5, and 2.5 %. (2) Fermentation time: 8, 12, and 16 hours. The observed variables included chemical (pH, total titrated acid/TTA, anthocyanins), microbiology (lactic acid bacteria/LAB), and sensory. The fermentation time affects the pH value and TAT. The 12 hours of fermentation time gave pH and TTA values, respectively: 3.77 and 1.23%. The variation in the addition of roselle extract significantly affected the anthocyanin, TTA, and LAB values. The addition of the extract as much as 1.5% gave the anthocyanins, TTA, and LAB value respectively 0.871 mg/mL, 1.31%, 561.11x 107CFU/mL. The best treatment was yogurt with a roselle extract concentration of 1.5% and 20 hours of fermentation. This yogurt had characteristic as follows: pH 3.7, TAT 1.33%, anthocyanins 0.8751 mg/mL, LAB 560 x 107 CFU/mL, reddish-yellow (4), distinctive aroma (4), Sour taste (4), fine texture (4), and liking (4).

The white shrimp (Penaeus merguensis)is abundant in Indonesia which could be made the jerky product to increase its shelflife. This study was aimed to determine the quality and shelflife of vacuum and non- vacuum packed white shrimp jerky stored at room temperature. And, the packed of white shrimp jerky was stored at room temperature for 0, 3, 6 and 9 days. The data obtained were analyzed using paired sample t-test. The condition of packaging had affected the quality and storage times for this jerky. The average water content value was 23,01% (dry basis,db) for all the treatments. For 9 days, the TVB-N (total volatile based- nitrogen) and TPC (total plate count) were 22,41% mgN/100g and 3,27 log CFU/g (vacuum packed), then 26,52 mgN/100g and 6.12 log CFU/g (non-vacuum packed), respectively. During storage, total yeast and fungi, as well as aw (activity water), have increased. The vacuum- packaged white shrimp jerky was the best option for storing this product, and it has a shelflife of up to 9.
Detecting Global Influence of Transcription Factor Interactions on Gene Expression in Lymphoblastoid Cells Using Neural Network Models.
Authors: Patel Neel , Bush William S. 
Published: August 2021

Abstract
Background Transcription factor(TF) interactions are known to regulate gene expression in eukaryotes via TF regulatory modules(TRMs). Such interactions can be formed due to co-localizing TFs binding proximally to each other in the DNA sequence or between distally binding TFs via long distance chromatin looping. While the former type of interaction has been characterized extensively, long distance TF interactions are still largely understudied. Furthermore, most prior approaches have focused on characterizing physical TF interactions without accounting for their effects on gene expression regulation. Understanding how TRMs influence gene expression regulation could aid in identifying diseases caused by disruptions to these mechanisms. In this paper, we present a novel neural network based approach to detect TRM in the GM12878 immortalized lymphoblastoid cell line. Results We estimated main effects of 149 individual TFs and interaction effects of 48 distinct combinations of TFs for their influence on gene expression based on the neural networks trained to predict gene expression using multi-omics TF regulatory features. We identified several well-known TF interactions and discovered multiple previously uncharacterized TF interactions within our detected set of TRMs. We further characterized the pairwise TF interactions using long distance chromatin looping and motif co-occurrence data. We found that nearly all the TFs constituting TRMs detected by our approach interacted via chromatin looping, and that these TFs further interact with promoters to influence gene expression through one of four possible regulatory configurations.Conclusion We have detected TRMs using neural network models based on regulatory features. We have also described these TRMs based on their regulatory potential along with presenting evidence for the possibility of TF interactions forming the TRMs occurring via chromatin looping.

Abstract
Background: Tracheostomy is one of the more commonly performed procedures in critically ill patients. Postoperative scarring is one of the bothersome sequelae of tracheostomies. Scars distorted the physical appearance, especially when found on the head and neck, which could cause a negative impact on quality of life. The aim of this study was to evaluate and assess the impact on quality of life of post-tracheostomy`s scars, depending on the method of tracheostomy.Methods: The prospective, single-center observational case-control study was conducted. One hundred and fifty-six persons with more than four months of post-tracheostomy surgical scars presence were observed using the Patient and Observer Scar Assessment Scale and Dermatology Life Quality index questionnaire. Persons were divided on two groups depending on method of performed tracheostomy, and duration of cannulated period was considered in both groups. Statistical analyses were performed by using SPSS ver. 16.0 (SPSS Inc., Chicago, IL, USA) and p-values of <0.05 were considered significant.Results: The patients who had a tracheostomic tube cannulation period of less than 15 days had better cosmetic results than those who had tracheostomic tubes for more than 15 days, regardless of the method of tracheostomy 6.64± 0.082 vs. 16.15± 0.096 (p<0.001) in surgical tracheostomy group and 7.26± 0.211 vs.14.17± 0.379 (p<0.05) in percutaneous dilatational group. The Dermatology Life Quality index scores have shown a mean value of 0.6 ±0.01, which means that post-tracheostomy scarring in the presented study, had no effect on the person's quality of life.Conclusions: Aesthetic outcomes of post-tracheostomy`s scars after the open surgical tracheostomy technique, performed using a minimally invasive approach, did not statistically differ from those of the percutaneous dilatational technique. Persons with a long duration of tracheostomic tube ventilation showed worse aesthetic outcomes compared with short-term tracheostomic cannulation, not dependent on the tracheostomy performing technique.The Dermatology Life Quality index have shown that post-tracheostomy`s scarring in the presented study had no effect on the person's quality of life.Trial registration: ISRCTN24668317 (IRB no.YSMU №7/18-19).

Published: August 2021

Abstract
Enydra fluctuans DC. (Asteraceae) is an edible semi-aquatic floating or trailing herbaceous plant widely distributed in tropical Africa, South and South East Asia, and Australia. Its leaves, which are consumed as a vegetable, are also used in traditional medicine to treat several diseases. The efficacy of this plant in removal of copper and lead from aqueous medium was tested in the present study. Accumulation of both Cu and Pb was significantly higher in root than that in leaf and stem. Though all the bioconcentration factor (BCF) values were greater than unity, none of the translocation factor (TF) values was greater than unity, indicating that this plant could not be considered a hyperaccumulator of these metals. Nevertheless, E. fluctuans could remove Cu from aqueous medium at rates ranging from 98.8–99.7 %, with a mean reduction of 99.2 % after 96 h exposure at various concentrations. The removal of Pb ranged from 97.1–99.1 %, with a mean reduction of 98.2 %. Thus, E. fluctuans showed high potential in removal of Cu and Pb from aqueous medium, and has the prospect of being used in phytoremediation of these metals.
