Effect of formaldehyde-based additive against African swine fever virus in complete swine feed
Authors: Ly V. D. , Hoang T. V. , Dang A. K. , Aupanun S. , Wongpukdee C.
Published: August 2022

African swine fever (ASF) is currently considered the serious contagious disease of the swine in-dustry worldwide. The feed and feed ingredients have been recognized as a potential risk factor for Af-rican swine fever virus (ASFV) transmission. No commercial vaccines and effective drugs against ASFV are available to date. This study aimed to examine the antimicrobial SALTEC™ 512, a formal-dehyde-based additive, at an application rate of 1.0; 2.0; and 3.0 kg/t feed against ASFV in complete swine feed. The effect of SALTEC™ 512 was evaluated by a contaminated ASFV feed assay. Our study reveals that SALTEC™ 512 inactivated ASF/VN/Pig/Hue/1270 strain in complete swine feed at an inclusion rate of 1.0 kg/t feed on Day 1 post inoculation. The most effective action was noticed at an inclusion level of 3.0 kg/t feed on Day 7 post inoculation. The antiviral activity of SALTEC™ 512 against ASF/VN/Pig/Hue/1270 was dose and time-dependent. Overall, SALTEC™ 512 may be a po-tential additive to reduce the risk of ASFV transmission via feed contamination.
Morfologías y patrones urbanos en conjunto de vivienda palafítica. Vivienda vernácula en el corregimiento de El Morro (Nueva Venecia), en el municipio de Sitionuevo, Magdalena, Colombia
Authors: Medina-Garzón Harold , Arteaga-Botero Gustavo Adolfo , López-Pérez Cecilia
Published: August 2022

Los patrones de agrupación presentes en un conjunto urbano de pequeña escala en la costa norte de Colombia son el objeto de estudio. Al iniciar las observaciones, la vivienda local mostró las particularidades constructivas generadas por la necesidad de edificarla sobre el agua. Este atributo especial dentro de las arquitecturas vernáculas en Colombia señaló una condición por desarrollar. Analizar el contexto de estas arquitecturas y enmarcar las configuraciones del conjunto fueron las dos partes del desarrollo de la investigación. Con los resultados se contrastaron las características del conjunto y los patrones o los atributos que describen las lógicas de este proceso particular, se desarrolló una metodología para abordar cómo combinar dos aspectos: por una parte, las lógicas constructivas usadas para las viviendas de la zona (los materiales, los sistemas y las lógicas constructivas); por otra, cómo pasan a otra lógica: una de agrupación o de conjunto. En este último aspecto, las morfologías y las tipologías particulares son algo por referenciar con detalle en Colombia, en marco de lo vernáculo o las arquitecturas rurales.
Incidencias del arte urbano en la configuración de la ciudad. El caso de Medellín, Colombia
Authors: Gaviria-Puerta Nino
Published: August 2022

Las implicaciones que los procesos sociales tienen sobre las intervenciones gráficas, pictóricas o tipográficas reflejadas en el espacio público en la ciudad de Medellín, conforman estrategias que contribuyen a su configuración física y simbólica; complementariamente, se encuentra la pregunta por la imagen resultante del espacio público, la cual, moldeada a partir de dichas intervenciones, posibilita la emergencia de un paisaje urbano vivo y vibrante, en el que la proliferación de imágenes de todo tipo abunda en sus muros, sus calles, sus barrios y sus comunas. Metodológicamente, el tema de las intervenciones gráficas en el espacio público implica la recolección de información y los análisis posteriores se vienen realizando a través del mapeo de los lugares en los que éstas se presentan, las técnicas empleadas, los autores, las estrategias y los programas. Se combinan observaciones y descripciones de espacios públicos con levantamientos fotográficos de los mismos; también se emplean las entrevistas con los autores de las obras en el espacio público, con promotores y curadores de arte urbano, para ir dilucidando las motivaciones que dan cabida a este tipo de actuaciones. Finalmente, el trabajo de campo se complementa con búsquedas bibliográficas en diversas fuentes acerca de fenómenos como el grafiti, el arte urbano, la fenomenología de la percepción, el espacio público y el paisaje urbano en la ciudad contemporánea.
An Intercultural Experience in European Art and Decorative Design by Chinese Students in Italy
Authors: Ha Sha
Published: August 2022

The paper describes the encounter with Italian fine arts and decorative design by a group of 17 Chinese Junior High School, art loving students, during their 2019 summer vacations. According to a ‘cooperative learning’ strategy, the students had been subdivided into four groups, under the guidance of four Chinese teachers, each one responsible for a single group, and the assistance of an Italian artist and an expert teacher herself. During the period of two weeks the students visited historical buildings and museums in the art cities of Venice, Padua, Florence and Rome. In the evening, in the presence of their teachers, they took part to collective discussions on the meaning and impact on them of the most significant art works they encountered during the day. They also took part, in Padua, in an animated ‘active learning’ session in Jewelry Design. That intercultural experience turned out to be very stimulating for those students: part of them included the study of classical art/decorative design in their high school curricula.
A People’s Criminologist in An Age of Trumpian Populism: On the Praxis of Newsmaking and Monetizing
Authors: Barak Gregg
Published: August 2022

This self-ethnography is about a radical or people’s criminologist in an age of Trumpian populism. It offers a case study on the theory and practice of newsmaking criminology and of monetization of the Trump book industry. After establishing what newsmaking criminology is as the originator of the concept and providing an overview of 35 years of newsmaking, I pivot to an examination of three elements—commentaries, publicity, and digital content—that are associated with “socially mediated newsmaking” and the monetizing of Trump, criminology, and criminologists. This is followed by a discussion and evaluation of the merits of newsmaking criminology in general and of this newsmaking excursion into social media. Finally, I call for more criminologists to become newsmakers to take on the “crimes of omission” by the 4th Estate.
Uczeń z doświadczeniem migracji na lekcji języka angielskiego: wyzwania i rozwiązania
Authors: Rokita-Jaśkow Joanna
Published: August 2022

The increasing number of migrant learners in Polish schools poses a new challenge not only for teachers of the language of school education, i.e. Polish, but also for teachers of other subjects, including English. Depending on the migrant learner’s country of origin, English may be his/her foreign, third (or additional) or even first language. This situation increases the heterogeneity of the language group and raises new challenges, which according to Ruiz’s (1984) conceptualization could be approached by the teacher either as a threat to the monolingual policy in the classroom, or as a resource that has the potential to enrich foreign language lessons by developing plurilingual and intercultural competences. On the basis of available research (Rokita-Jaśkow, 2019, 2021), the article presents the challenges teachers face along with suggestions for teaching solutions.
Przygotowanie uczniów do międzynarodowych certyfikatów językowych Fit in Deutsch 1 i 2 jako sposób na wykorzystanie potencjału ucznia zdolnego w rozwijaniu kompetencji językowej na poziomie A1/A2
Authors: Gierzyńska Marta
Published: August 2022

This article is devoted to the issue of special educational needs in the context of working with a gifted learner, with particular linguistic abilities. Satisfying the needs of such children and providing them with opportunities for integral development of linguistic competence demands a different educational approach – similar to the situation when working with students with some limitations in their learning processes. The approach taken reflects the concepts and definitions of abilities presented in this article. The analysis of those elements suggests ways of identifying gifted learners and, as the next step, also offers certain educational solutions which can easily be applied in teaching. One such way can be preparing children and teenagers for international language certificates in German – Fit in Deutsch 1 and 2 as a form of extra-curricular activities. These certificates are at the A1/A2 level of language skills according to the Common European Framework of Reference for Languages (CEFR). As they are aimed at young people aged 10–16, it is possible to include primary school students in preparation for them, which in turn allows the learners to develop language skills and linguistic interests at the second stage of education. This article serves as a general overview and should not be taken as an empirical research.
In vitro thrombogenicity evaluation of rotary blood pumps by thromboelastometry
Authors: Klein Mario , Tack Jana Christine , Mager Ilona , Maas Judith , Schmitz-Rode Thomas , Arens Jutta , Steinseifer Ulrich , Clauser Johanna Charlotte
Published: August 2022

In vitro thrombogenicity tests for rotary blood pumps (RBPs) could benefit from assessing coagulation kinematics, as RBP design improves. In this feasibility study, we investigated if the method of thromboelastometry (TEM) is able to assess coagulation kinematics under the in vitro conditions of RBP tests. We conducted in vitro thrombogenicity tests (n=4) by placing Deltastream® DP3 pumps into test loops that were filled with 150 mL of slightly anti-coagulated porcine blood, adjusted to an activated clotting time (ACT) well below clinically recommended levels. Blood samples were taken at certain time points during the experiment until a continuous decrease in pump flow indicated major thrombus formation. Blood samples were analyzed for ACT, platelet count (PLT), and several TEM parameters. While visible thrombus formation was observed in three pumps, ACT indicated an ongoing activation of coagulation, PLT might have indicated platelet consumption. Unexpectedly, most TEM results gave no clear indications. Nonetheless, TEM clotting time obtained by non-anticoagulated and chemically non-activated whole blood (HEPNATEM-CT) appeared to be more sensitive for the activation of coagulation in vitro than ACT, which might be of interest for future pump tests. However, more research regarding standardization of thrombogenicity pump tests is urgently required.
Micro Data on Robots from the IAB Establishment Panel
Authors: Plümpe Verena , Stegmaier Jens
Published: August 2022

Micro-data on robots have been very sparse in Germany so far. Consequently, a dedicated section has been introduced in the IAB Establishment Panel 2019 that includes questions on the number and type of robots used. This article describes the background and development of the survey questions, provides information on the quality of the data, possible checks and steps of data preparation. The resulting data is aggregated on industry level and compared with the frequently used robot data by the International Federation of Robotics (IFR) which contains robot supplier information on aggregate robot stocks and deliveries.
Pre-field phobia – About formal and meaning-related prohibitions on starting a German V2 clause
Authors: Meinunger André
Published: August 2022

German is a V2 language, i.e., a declarative clause has the finite verb in the position immediately after the first constituent. Traditionally, this order is derived by raising the verb to C and putting a single constituent into the so-called pre-field. Arguably, there are three options to fill the first position: (i) topicalization (A’-movement), (ii) formal movement, which raises the highest constituent in the ongoing derivation (A-movement), or (iii) merging a constituent which is only legitimate there (base-generation). Theoretically, any major constituent can occupy the pre-field. However, it has been observed that certain expressions cannot appear there. In its narrower focus, the paper argues that there are more pre-field-phobic expressions than standardly assumed, and that these expressions, although at first glance heterogeneous, fall into two classes. One can be defined structurally and is considered in the second part of this paper; the other class can be captured in terms of meaning and comprises a specific type of expressive adverbial (discussed in the first and main part). The paper’s message in a broader sense is that syntax restricts the occurrence of expressive expressions. It is shown that the sentence-initial position in German does not allow material which is exclusively use-conditional in the sense of expressive meaning.

Diabetic ketoacidosis after the treatment of anaphylaxis
Authors: Brenner Daniel S , Kleinman Keith , Manzo Amy , Bembea Melania M , Cooke David W
Published: August 2022

Anaphylaxis is a rapidly progressive potentially lethal condition, and epinephrine is the most crucial medication in its treatment. In this study, we present a case of diabetic ketoacidosis in a young woman that was precipitated by the administration of epinephrine to treat anaphylaxis. This patient had diabetes mellitus and poor glycemic control and developed ketoacidosis despite having evidence of ongoing endogenous insulin production and having been treated with exogenous long-acting insulin less than 24 h prior to the event. This is a rare, serious, adverse side effect of life-saving medication. This report demonstrates that the risk of diabetic ketoacidosis should be considered when administering epinephrine to patients with diabetes, even in the absence of complete insulin deficiency.

Learning points

Epinephrine directly suppresses insulin secretion, stimulates lipolysis, and causes ketone body generation.

High-dose catecholamine administration can cause unexpected diabetic ketoacidosis in patients with risk factors.

Early administration of insulin may not protect patients from developing ketoacidosis in the setting of high-dose catecholamine administration.
Oro chocoano: semiótica discursiva de los líderes sociales en Río Quito, Quibdó (Colombia)
Authors: Buitrago Rojas Andrea , Mendoza Torres Johan Andrés , Chavarro Ospina Sharon Gabriela
Published: August 2022

Esta investigación muestra la relación entre la explotación del oro, el conflicto armado en Colombia, el racismo estructural y el impacto ambiental, a partir del caso de las comunidades negras que habitan en Río Quito, Quibdó, Chocó. Se implementó la etnosemiótica estructural de Greimas, para analizar las entrevistas a líderes sociales y comunitarios de la región, y se identificaron los tres niveles semióticos: (1) semiótica de la acción, el desarrollo de la extracción minera por las comunidades negras; (2) semiótica cognitiva, la anomia y antinomia estatal en la regulación de la explotación del oro; y (3) semiótica de las pasiones, que correspondió al miedo como creencia y la identidad étnica como conocimiento ancestral sobre el territorio y el río. La tesis se enmarca desde la autonomía y la autodeterminación de la identidad que han asumido y resistido las comunidades negras; la antítesis se registra en la inseguridad que presupone el miedo respecto a las dinámicas entre los diversos actores del conflicto armado, bajo el contexto de la explotación minera; y la síntesis es el discurso de la paz como expectativa. Finalmente, se perfila el río como la relación estructural de la totalidad de las variables de estudio.
Patrimonio cultural: entre el producto y el proceso. Concepto, categorías y discursos
Authors: Del Huerto Revaz María , Curia Cristina Alejandra , Yuln Melina
Published: August 2022

Durante las últimas décadas, la ampliación del concepto, las categorías de análisis y los discursos sobre el patrimonio cultural han planteado cambios significativos y complejos. Con el propósito de indagar estos recorridos, se consideran perspectivas de análisis que incorporan diversas categorías sociales en la construcción de los relatos sobre el patrimonio cultural. Para este estudio, se ha empleado la teoría social de los discursos de Eliseo Verón, a modo de recurso analítico, cuya metodología de abordaje permite indagar el patrimonio como repertorio de manifestaciones socialmente reconocidas y configuraciones históricas. Se espera que el recorrido propuesto contribuya a la discusión y revisión de miradas y perspectivas en el análisis del patrimonio cultural, en el marco de una construcción social imbricada en cambios constantes.
Los fines de la educación superior en Latinoamérica
Authors: Martínez Gómez María Celia , Letor Mena Dominique
Published: August 2022

La Universidad es una comunidad de personas en la que se elaboran y transmiten conocimientos. Autores del siglo XX determinan que su misión original es la búsqueda de la verdad, acompañada de sus fines: la formación de la persona, la formación de profesionales y la investigación. En el siglo XXI, la realidad es otra: las universidades latinoamericanas están dirigidas a la contribución del desarrollo de la responsabilidad social universitaria, que ha sido denominada en la actualidad como una de sus principales misiones, lejos de sus fines originales. La razón de tal situación radica en que las instituciones de educación superior buscan responder a las demandas del mercado, adoptando características como la relación Universidad-empresa, la calidad académica, los sistemas de acreditación y los rankings. Ante tan apremiante situación, es emergente que las universidades latinoamericanas dirijan su quehacer hacia el cumplimiento de su misión original y busquen un equilibrio entre las demandas del mercado, del Estado, de la sociedad, sus misiones y sus fines, sin inclinarse hacia el paradigma del producto, y manteniéndose en el paradigma de la verdad que busca la formación integral.
Educación intercultural crítica: una alternativa para la construcción del posconflicto colombiano
Authors: Oses Gil Alejandro , Cabeza Herrera Oscar Javier , Flórez Pabón Campo Elías , Botero Urquijo Diego Alejandro
Published: August 2022

Introducción. La educación intercultural crítica es una propuesta viable y necesaria para hacer realidad los acuerdos de paz y la construcción del posconflicto. Así, es preciso conocer las causas y las consecuancias del conflicto y la relación con la problemática de una educación intercultural funcional al Estado. Metodología. Es una revisión descriptiva. Se analizaron fuentes directas e indirectas conexas al propósito del estudio, desde una visión integradora. Las fuentes primarias y secundarias se obtuvieron de distintas bases de datos como Redalyc, Latindex, Clacso, Sciencedirect, Scopus, Cepal, así como de referencias de libros de texto. Resultados. Se trabajaron seis tópicos en la revisión: (1) focalización del conflicto histórico en Colombia, (2) asimetría y discriminación sociocultural, (3) la interculturalidad: el camino hacia el reconocimiento del otro, (4) la experiencia de educación intercultural en Colombia, (5) educación intercultural crítica: aprendizajes inter-epistémicos, y (6) educación intercultural crítica y posconflicto. Estos tópicos permiten plasmar la necesidad de una aproximación al sentido sociopolítico de la educación intercultural crítica en Colombia, como mecanismo para promover los acuerdos de paz. Conclusión. Colombia es un país diverso socioculturalmente, pero no basta con enunciarlo, hay que realizarlo con la educación intercultural. Este tipo de educación crítica valora los saberes locales no cientificistas, restituye y reivindica la autonomía de sus experiencias epistémicas y legitima el derecho intracultural e intercultural de los pueblos.
El estudio de los movimientos sociales en tiempos de crisis en América Latina. ¿Dónde estamos? ¿Hacia dónde vamos?
Authors: Paredes P. Juan Pablo , Urra Canales Miguel , Uribe Mendoza Cristhian
Published: August 2022

Han pasado cuatro décadas desde que, en 1983, el sociólogo boliviano Fernando Calderón publicó su estudio inaugural sobre la “política en las calles” para referirse a una forma de política por fuera de lo institucional y que implicaba la acción colectiva de actores sociales considerados tradicionalmente “no políticos” (Calderón, 1983) —como el campesinado y el mundo indígena— en la ciudad de Cochabamba durante dos décadas (1950-1970). Cuatro años después, el mismo Calderón publicó, al alero de Clacso, su hoy clásico libro compilado Movimientos sociales ante la crisis (Calderón, 1986), en el que se constata la relevancia de los movimientos sociales en periodos de inestabilidad social y autoritarismo político. Algunos años antes, en Europa, Alain Touraine, junto a un equipo de investigadores asociados al Centro de Análisis y de Intervención Sociológicos (CADIS) en Francia, estudiaron la presencia de los movimientos sociales como actores que producen y disputan la configuración de la sociedad. Allí, Touraine desarrolló una teoría de la acción social que tenía en su centro a lo que después se denominó “nuevos movimientos sociales”, con lo cual se abre a estudiar no solo las clases sociales, sino también las luchas urbanas, estudiantiles, y de mujeres, entre otras.
The effects of using different adhesive on the thickness swelling ratio of LVL produced from scotch pine
Authors: Esen Rasit , Likos Erkan , Zengin Gözde
Published: August 2022

Most wood properties are affected by changes in moisture content below the wood fiber saturation point. In this study, the thickness swelling ratios of laminated veneer lumber (LVL) produced from Scotch pine (Pinus sylvestris L.) bonded by using polyvinyl acetate (PVAc), polymeric diphenyl methane diisocyanate (pMDI), and a mixture of them were evaluated. Thickness swelling of the samples was calculated after different waiting times under water. While the lowest thickness swelling ratio (1.65%) was determined from bonding with PVAc 92%- pMDI 8%, for 2 hours, the highest thickness swelling ratio (6.35%) was observed from bonding with PVAc 98%- pMDI 2% adhesive for 96 hours. As a result, adding pMDI to the PVAc adhesive reduced the rate of swelling of the test specimens. For this reason, the material can be used potentially in wet or humid places.
Preparation and characterization of textile-grade long cellulose fibers and their yarns from windmill palm
Authors: Chen Changjie , Xu Pengfei , Wang Zhong , Shi Jingjing , Wang Guohe , Wang Xinhou
Published: August 2022

Windmill palm fiber (WPF) is an abundant source of cellulose fiber that can be used in textile manufacturing. In this study, acid-alkali palm fiber and acid-alkali-enzyme palm fiber were prepared to create blended yarns. The morphology, chemical composition, physical structural parameters, and tensile properties of the WPF samples and yarns were studied. The results indicated that both the acid-alkali and acid-alkali-enzyme treatments can be used as degumming methods to prepare windmill palm textile-grade long fibers with spinning ability. After chemical treatment, the cellulose content of WPF increased to more than 60%, up from 34%. However, the line densities of the acid-alkali and acid-alkali-enzyme textile-grade long fibers decreased to 5.29 ± 1.00 tex and 4.52 ± 0.82 tex, respectively. For the enzyme-treated fiber, a stratification phenomenon of the fiber cell walls and a decrease in the modulus were observed. The palm/cotton yarn had a high tensile strength and strip uniformity.
Study on the relaxation behavior of bamboo fiber as a function of temperature and moisture content
Authors: Shih Zong-Ting , Young Wen-Bin
Published: August 2022

The tensile relaxation behavior of bamboo fiber was evaluated. Bamboo fibers were extracted via a mechanical method and treated in alkaline solutions of sodium hydroxide. The relaxation tests of bamboo fibers were conducted by applying a constant strain at one end of a single bamboo fiber while the other end was fixed. The reaction force in the bamboo fiber was measured at the same time. The relaxation tests of the bamboo fibers were conducted under different temperature and moisture contents. The results showed that in the wet and/or high temperature conditions, the relaxation rate was faster than that in the dry and/or room temperature conditions. For a low strain, the bamboo fiber can be totally relaxed within 10 min under a high temperature. A nonlinear viscoelastic constitutive model was proposed to fit the relaxation curves, which could model the stress relaxation behavior of a bamboo fiber under different temperature or moisture content conditions. Compared with the experimental data, the model gave reasonable values for the relaxation behavior of the bamboo fiber.
Transfer of the interlaminar shear test to veneer layer-based composites for qualitative evaluation of layer adhesion
Authors: Siegel Carolin , Buchelt Beate , Wagenführ André
Published: August 2022

This study aimed to investigate the suitability of the interlaminar shear (ILS) testing method for veneer-based composites. The ILS testing method is an established method for composite materials as a qualitative evaluation of the adhesion within the composite. The applicability of this method to veneer based composites enables a simple qualitative statement on the adhesion of the individual layers. The ILS method complements existing wood-based material tests that focus on bonding, using significantly smaller material dimensions.
Defectos óseos glenohumerales: Un recorrido por los avances diagnósticos y terapéuticos durante los últimos 20 años
Authors: Mejía-Grueso Alejandro , Gutiérrez-Zúñiga Daniela , Visbal-Otero Nicolle , Valbuena-Bernal Felipe
Published: August 2022

Introducción: El abordaje y el tratamiento de los defectos óseos glenohumerales han evolucionado con la intención de brindar un manejo más individualizado para los pacientes. Sin embargo, hasta la fecha, no existen artículos que recopilen dichos avances históricos.

Objetivo: Describir la bibliografía más relevante sobre el análisis diagnóstico y las opciones terapéuticas de los defectos óseos glenohumerales en los últimos 20 años.

Materiales y Métodos: Se realizó una búsqueda en la base de datos PubMed con los términos “Glenoid defect”, “Humeral defect”, “Shoulder instability” y “Glenoid track”, filtrada por año desde 2000 hasta2021. Se incluyeron estudios publicados en inglés y español, de pacientes adultos.

Resultados: En la búsqueda, se revisaron 56 artículos según los criterios planteados. Se llevó a cabo una revisión narrativa cronológica sobre el abordaje de los defectos óseos glenohumerales en inestabilidad anterior.

Conclusiones: Los avances tecnológicos han permitido desarrollar algoritmos de evaluación y manejo dirigidos a lograr los mejores desenlaces según las características de cada paciente. La bibliografía actual recomienda el tratamiento quirúrgico basado en la medición objetiva de los defectos óseos glenohumerales, para lo cual la artroscopia y la tomografía con reconstrucción 3D ofrecen la cuantificación más acertada.

Dislocación y decisión. Hacia una teoría deconstructiva del sujeto político en el trabajo de Ernesto Laclau
Authors: Guille Gustavo Patricio
Published: August 2022

La cuestión de la constitución del sujeto político ha sido uno de los ejes centrales del pensamiento de Ernesto Laclau. En el presente trabajo nos centramos en un período específico de su reflexión teórica en torno a esta problemática: entre los años posteriores a la publicación de Hegemonía y estrategia socialista (1985) y la aparición de La razón populista (2005). Consideramos que esta etapa de su pensamiento puede ser interpretada como el intento por elaborar una teoría deconstructiva del sujeto político, la cual se sostiene sobre dos nociones que cobran vital importancia en este período: la decisión (tomada siempre en un terreno indecidible) y la dislocación.
Hiperpolítica. Una reflexión sobre el pensamiento esferológico de Peter Sloterdijk
Authors: Maureira Marco
Published: August 2022

El presente artículo tiene por objetivo realizar una breve reflexión sobre la propuesta filosófica de Peter Sloterdijk a partir del concepto de “hiperpolítica”. Para tal fin, comenzaremos por analizar su esquema de tres etapas históricas (horda primitiva, sociedad agrícola y sociedad industrial) y sus correspondientes modelos políticos de referencia (paleopolítica, política tradicional e hiperpolítica). A partir de lo anterior, problematizaremos qué quiere decir concretamente el prefijo hiper-, lo cual nos conducirá a la emergencia de un nuevo prefijo rector de lo político que aparece en su obra posterior: a saber, lo antro-político y el protagonismo de la antropo-técnica, como prisma comprensivo y alternativa de acción para las actuales sociedades posindustriales y postmetafísicas.
Renovación y autonomía. Justificación epistémica y responsabilidad ética en la filosofía de Edmund Husserl
Authors: Ainbinder Bernardo
Published: August 2022

El artículo sostiene que la concepción fenomenológica de la justificación epistémica y su modo de elucidar la objetividad depende de la vigencia de un cierto ideal de racionalidad como ideal ético que orienta nuestras acciones. Se trata de lo que Husserl denomina el ideal de renovación, que cumple una doble función: a) da cuenta de la tendencia normativa a la corrección sobre la que se asienta la comprensión husserliana de la objetividad, y b) da cuenta de la motivación sobre la que se asienta la adopción de una actitud peculiar, la actitud fenomenológica o trascendental, que caracteriza al quehacer filosófico.
Cultura y tecnificación en los primeros filósofos colombianos de la normalización
Authors: López Carlos Arturo
Published: August 2022

La novedad de las prácticas filosóficas asociadas a la fundación del Instituto de Filosofía de la Universidad Nacional y a la revista Ideas y valores, proyecto intelectual conocido a posteriori como la “normalización” de la filosofía, no depende de una inusitada inserción de la actividad filosófica en la cultura nacional. Más bien, lo nuevo en los trabajos filosóficos de los primeros normalizadores fue concebir la actividad filosófica universitaria, por un lado, como un producto cultural y, por otro, como una práctica profesional urgida de un desarrollo técnico conforme a estándares internacionales. En este artículo se muestra que, en el proceso de asimilación de esta novedad, la actividad filosófica se fue distanciando de su dimensión cultural.
Silenciamientos, enfoques y escrituras de la filosofía en Colombia. Para una relectura de Ideas… y Valores (1951-1954)
Authors: Betancur Gómez Juan Camilo
Published: August 2022

El presente trabajo discute el relato de la “normalidad filosófica”, tal como se decantó en algunas versiones posteriores a 1980, con varios elementos de la producción textual de la filosofía en Colombia, entre 1940-1950. A partir de la exposición de distintos enfoques textuales en la escritura de 1940-1950, se dará cuenta del programa o las aspiraciones que algunos escritores depositaron en la filosofía, para poner esto como trasfondo de la revista Ideas y Valores y proponer así una mirada más completa a los textos de los primeros años.
El melancólico ensimismamiento. ¿Un problema consigo mismo o una aporía en el sí mismo?
Authors: Johnson Felipe
Published: August 2022

Este artículo se propone pensar el ensimismamiento característico de la melancolía en vistas a comprender su particular endon. Siguiendo las discusiones que ha mantenido la psiquiatría fenomenológica con las tesis heideggerianas sobre el miedo y la angustia, intentaremos mostrar que la melancolía, pese a poder ser entendida como un retraimiento del mundo y como una relación consigo mismo de autorreproche, puede ser pensada también como una condición vital que radicaría en un movimiento de autoanulación albergado en la propia relación del existir consigo, mientras se despliega en el mundo. Así, se esbozará una reflexión en la que la melancolía pueda ser entendida como una aporía a partir de las consideraciones kierkegaardianas sobre la desesperación en cuanto enfermedad mortal.
Crítica y resistencia en Martin Heidegger y Theodor Adorno
Authors: Verano Leonardo
Published: August 2022

El diálogo propuesto entre Heidegger y Adorno, específicamente en lo que concierne a las ideas de crítica y de resistencia, no desconoce la importancia que adquiere para el último la crítica extensa que él mismo dirige a la ontología de Heidegger, ni para este su cuestionamiento de la filosofía dialéctica. El artículo busca mostrar que, en ambos autores, la idea de crítica y de resistencia se resuelve como indagación del sentido negativo de la experiencia. Se concluye que, destacando semejanzas y diferencias en sus planteamientos, la reivindicación del carácter negativo de la experiencia equivale reivindicar el poder crítico de la filosofía y del arte.

Se distinguen operaciones categoriales inmanentes a la formación de conceptos a partir del despliegue del acto fundamental de la objetivación, identificable con la tematización y con las direcciones en que esta se ejecuta. Se aclara cuál es el Grundhaltung de la filosofía para mostrar que este se caracteriza por un Gegenbewegung o Gegenzug.
La diosa Deméter. Maternidad beligerante, ecofeminismo y ética del cuidado en la mitología griega
Authors: Fernández Guerrero Olaya
Published: August 2022

En el contexto griego clásico, Deméter era venerada como diosa de la agricultura y protectora de la fertilidad. Asimismo, la relación entre esta deidad y su hija Koré-Perséfone representaba la fortaleza del vínculo maternal. Este artículo explora las dimensiones simbólicas de esta figura mitológica, poniendo de relieve sus conexiones con un modelo ético de maternidad asociado al cuidado y a la resistencia frente a las injusticias. Además, se aborda una lectura de este mito desde la perspectiva de la teoría feminista contemporánea, mostrando su cercanía con los planteamientos del ecofeminismo.

Published: August 2022

This project investigated the effect of compacting pressure and sintering temperature on supports’ physical and mechanical properties. The supports were prepared by axial compacting of a Al2O3 powders using pseudoboehmita and silica gel as binder. Hydrated magnesium oxide was used as sintering helper. the prepared agglutinants were characterized by x-ray sedigraphy. The supports were synthesized by SEM and their compression strength and porosity were evaluated and characterized by EDX sweeping electron microscope (SEM). These binders and the helper were prepared by the sol-gel process.
The effect on lactic fermentation of concentrating inert material with immobilized cells in a calcium alginate biocatalyser
Authors: Serrato Juan Carlos , Caicedo Mesa Luis A
Published: August 2022

Colombia is one of the world’s main sugarcane cultivating countries but it has not diversified its fermentation industry; a few fermentation industries produce alcohol and yeasts. Lactic acid and its derivatives then become alternatives providing added value to the sugar produced, thus benefiting the regions producing the sugar. This work evaluated the kinetics of lactic acid production using immobilized cells in calcium alginate at different concentrations of inert material. Lactobacillus delbrueckii was the microorganism used and fermentation broth mainly consisted of sucrose and yeast exact. CSTR reactors were used without pH control. The results suggested that 2% to 3% inert material in the biocatalyst increased cellular retention and diffusiveness, leading to improved conversion and reaction rate.

Managing salinity in water associated with petrol industry production
Authors: Guerrero Fajardo Carlos Alberto , Escobar C Sandra , Ramírez N Diego
Published: August 2022

This article describes a conceptual design for handling an oilfield’s industrial wastewater; its objective was to use type-I fractioned crystallisation within a feasible environmental and technical framework for obtaining the highest percentage of salt. La Gloria, La Gloria Norte and Morichal (all belonging to the Casanare department association) stations were used for planning and analysing this handling alternative as they produce high salt-containing industrial effluent. This alternative was focused on treating 30% of the total volume of the associated water so produced. This volume is expected to be 1239 m3/d in 2000 in the oilfields being studied here. The process allows 92% retrieval from present NaCl (0.918 Ton/h), having 97% purity. Evaporation and aeration systems should be set prior to the crystallisation stage as a means of guaranteeing final product quality and making good use of the field’s facilities.

Published: August 2022

This work studied the liquid phase of acetic acid and butyl alcohol esterification reaction (Patm = 560 mmHg), using an ion exchange resin (Lewatit K-2431) as catalyst. A set of assays were carried out for determining the effect of catalyst load, temperature and molar ratio (acid/alcohol) on chemical equilibrium constant. Components' selective sorption on the resin matrix was noticed; its effect on equilibrium conditions was verified, by using different acid/alcohol starting ratios. A non-ideal model (UNIQUAC) was used for calculating component activities. Standard free energy and enthalpy of esterification were calculated (∆G° = -1.874 Kcal/mol, ∆H° = -5.335 Kcal/ mol), corresponding to reported data from previous work. An expression for calculating apparent equilibrium constant was obtained, considering thermal effects and those associated with liquid-polymer phase equilibrium. Such expression had good agreement with experimental and reported data.
Geotechnical information as an important element when planning and designing civil engineering work Bogota
Authors: Cangrejo Aljure Denisse , Gustavo Infante Carlos
Published: August 2022

The city of Bogota provides a dynamic scenario re civil construction work; it is thereby essential to have relevant information available for the suitable planning and evaluation of engineering work from both the structural and budgetary points of view. The moisture content of soil has become a most important variable, given its great impact on placing structures in Bogota. This is why this work on city zoning aimed at orientating planning and designing civil engineering work has been done according to the percentage of moisture in soil. Information from 43,000 initial samples was used for geostatistical analysis to predict soil moisture content through the whole area.
Four ranges of depth were used for establishing this variable's correlation with other physical variables. Factors were identified which led to understanding results regarding soil moisture content and its behavior in the area being studied. Areas were found having high percentages of moisture content in soil in the northeast of Bogotá and less moist areas in the soil towards the southeast and the east of Bogotá (Bogota’s eastern heights). Different behavior was found for moisture content at depths greater than 6 meters.

Published: August 2022

Reactive system (acetic acid-n-butanol-butyl acetate-water, in liquid phase, 0.76 Bar pressure) adsorption on a cationic exchange resin (Bayer Lewatit K-2431) was studied in this work. Solid particle size distribution was verified and low dispersion was noticed with 86% of total mass between 20 and 30 mesh. The dried solid showed a binodal distribution with 40% above 25 mesh and 45% between 25 and 45 mesh. Resin swelling assays were carried out on pure components and non-reactive binary mixtures and increased matrix volume was observed (2.2 to 3 times higher). Selective adsorption on the reactive system was observed in the sequence: water > n-butanol acid > acetate. Both ideal and non-ideal models were tested for calculating adsorption using a composite isotherm, demonstrating these models’ weakness in representing adsorption on ionic polymer matrices. Calorimetric characterisation assays were carried out on swelled catalyst and a change in solid structure caused by thermal treatment was recognised using infrared scanning.

This article intends to introduce features of MATLAB (version 6.1 onwards) which lets data be transferred through a serial port for reading it or writing it directly from Matlab. This can be done for supporting several commercial instrumentation interfaces or driving PC COM ports. This work is based on a micro-controlled system designed in such a way that the shape of an object can be recognised by ultrasonic echoes.
Predictive control applied to an evaporator mathematical model
Authors: Giraldo Giraldo Daniel Alonso , Santos Barbosa Dolly , Cotrino Badillo Carlos
Published: August 2022

This paper outlines designing a predictive control model (PCM) applied to a mathematical model of a falling film evaporator with mechanical steam compression like those used in the dairy industry. The controller was designed using the Connoisseur H software package and data gathered from the simulation of a non-linear mathematical model. A Control law was obtained from minimising a cost function subject to dynamic system constraints, using a quadratic programmed (QP) algorithm. A linear programming (LP) algorithm was used for finding a sub-optimal operation point for the process in stationary state.
A methodology for determining radiation form factors applied to particular plane-sphere configuration
Authors: Durán Peralta Héctor Armando , Caicedo Mesa Luis A
Published: August 2022

The form factor must be calculated when designing ovens and mechanisms heating or cooling systems by radiation, leading to determining heat transfer by radiation between surfaces which are at different temperatures. Heat transfer texts generally deduce and show the equation for obtaining the form factor between two surfaces which exchange heat by radiation for very simple configurations, but do not show how slightly more complex geometries and configurations are calculated. Many students who have studied heat transfer have the impression that form factors are calculated without any difficulty. Other students ask why the texts do not show how to calculate the form factor for slightly more complex configurations or for those which are more real. This document tries to answer these disquietudes as well as presenting a calculation strategy for purely pedagogical ends which can be applied to more complex configurations.
Using an infrared probe for in situ monitoring of esterifying reactions
Authors: Sánchez Castellanos Francisco José , Cesteros Carlos , Katime Issa A
Published: August 2022

A batch reactor was employed having pH meter, IR probe and continuous operation detectors so that it could work as a CSTR reactor. As esterification advanced, then IR bands corresponding to the carboxyl acid COOH group and the alcohol C-OH group decreased whilst a parallel increase was presented in the ester -COOR group band which was forming. Reaction progress could be observed by continuous IR spectrum registration. The IR band for HOH (water) could not be studied because it needed a completely anhydrous medium for doing so. Standard solutions could be prepared for quantifying IR band peak intensity, according to a component's composition in the mixture. However, when phase changes occurred in the reaction mixture, this method could not be employed for following the course of a particular reaction because random variation was detected in band intensity.
Rapid casting and new technologies in investment casting
Authors: Sánchez R Claudia Marcela , Cortés Rodríguez Carlos Julio
Published: August 2022

Rapid prototyping is a manufacturing process which is different to traditional methods as material is not removed or formed but added to obtain the designed pieces. It is not just used for manufacturing finished products but in manufacturing tooling for speeding up other manufacturing processes. This paper introduces rapid prototyping as a support technique for the lost wax process (investment casting). It gives a brief description of the different techniques implemented to date and materials used for making articles as part of the lost wax process.
