Published: August 2024

Resumen Los herpesvirus han sido considerados una de las familias virales más complejas no solo por su tamaño y estricto control de la replicación sino por su singular capacidad de establecerse en forma latente y reactivarse con o sin signos clínicos. En el presente artículo se revisan aspectos de la estructura molecular del HVB-1, su replicación y algunos de los mecanismos implicados en la latencia y reactivación de la infección viral.   Summary The herpesviruses have been considered among the most complex viral families due not only to their size and their strict replication control but also because of their singular capacity for establishing latency and reactivation with or without clinical signs. The present article reviews some aspects of the molecular structure of HVB-1, its replication and some of the mechanisms implicated in latency and reactivation of viral infection.

Resumen Con el propósito de ampliar la aplicabilidad de la técnica ELISA para el control de las enfermedades infecciosas, en el contexto de la ganadería nacional y específicamente para contribuir al conocimiento y al control de la Rinotraqueitis Infecciosa Bovina, se estandarizo una prueba ELISA en leche entera y se exploró la posibilidad de determinar un animal positivo en una mezcla de leches de varios animales negativos. Para el efecto se seleccionaron 127 animales que mediante pruebas previas de Neutralización y ELISA en suero sanguíneo, habían dado resultados concordantes. De estos animales se tomaron muestras individuales de leche y se estableció un punto de corte con base en los promedios de absorbancia de las muestras positivas y negativas. El análisis se hizo con el programa estadístico Medcalc, utilizando las curvas de respuesta operativa (ROC), e punto de corte resulto ser de 0.09 con un intervalo de confianza del 95% y una sensibilidad y especificidad del 94%. En cuanto a la posibilidad de probar mezclas de varios individuos, se determinó que una muestra de leche de un animal positivo, con una delta de absorbancia alto (> 0.20) se puede detectar hasta en 4-6 muestras negativas mientras que una muestra positiva, con una delta de absorbancia cercana al punto de corte (> 0.14), solo puede detectarse mezclada en una muestra negativa. Este estudio representa un aporte adicional al armamentario técnico para la investigación y el control o erradicación de la RIB.   Summary With the purpose of extending the applicability of the ELISA technique for the control of infectious diseases, in the context of national livestock and specifically to contribute to the knowledge and control of Infectious Bovine Rhinotracheitis (IBR), an ELISA technique was standardized in whole milk and the possibility of determining a positive animal in a mixture of samples from various negative animals was explored. For this purpose 127 animals were selected by previous testing of IBR antibodies by NT and serum ELISA. All these animals gave concordant results by both techniques. From these animals single samples of milk were taken and cut-off point was established. The analysis was done by Medcalc estadistical program, using responsive operative curves (ROC), the cut-off point was found at 0.09 and both, the specificity and sensibility were 94%. Also it was found that a single milk sample from one positive animal, with a high delta of absorbance (> 0.20) could be detected in mixture with 4-6 negative samples, while those positive but with a delta value near the cut-off point (> 0.14) could be mixed only with one negative sample to maintain its positivity. This study represents an additional contribution to the technical armamentarium for research and control or eradication of RIB.

Lymphocyte immunotherapy performed is pregnant gilts and sows did not affect preweaning mortality in the corresponding litters.
Authors: Maldonado J G , González M S , Otero A M
Published: August 2024

Summary This study was designed to test if lymphocyte immunotherapy (LI) of pregnant gilts and sows could improve preweaning mortality rates. In a commercial farm, Gilts (n = 61) first (n = 57) or second parity sows (n = 42) were selected and random assigned to treatment with saline (control group) or LI with lymphocytes obtained from multiparous sows, Boar, or growth-fattening pigs donors (alloimmunized groups). Treatments were performed at day 85 of pregnancy. Litter size and weight were evaluated by multifactor analysis of variance, whereas farrowing and preweaning mortality rates were analyzed by Mann-Whitney test. All traits evaluated at farrowing and at weaning did not significantly differ between groups (p > 0.05); when data from all immunized groups were altogether compared with control group (p > 0.5). Enteritis tended to be the most common cause of morbidity (p = 0.53). Mortality rate tended to increase in piglets from alloimmunized females (p = 0.12). The results suggest that LI of pregnant cross-bred gilts, first or second-parity sows did not affect preweaning mortality in piglets from subsequent lactation. Keywords: farrowing, litter size, litter weight, mortality, swine, weaning.      Resumen El presente estudio se diseñó para evaluar si la terapia con linfocitos alogénicos (LI) aplicada en cerdas gestantes podía reducir las tasas de mortalidad en lactancia de sus respectivas camadas. En una granja porcícola comercial se seleccionaron cerdas gestantes (80-90 días) de primera (n = 61), segunda (n = 42) gestación, y se asignaron al azar al tratamiento con 1) linfocitos alogénicos (grupos inmunizados) obtenidos de cerdas gestantes, machos reproductores o cerdos de engorde; o 2) con solución salina (grupo control). Los datos del tamaño y el peso de la camada al nacer y al destete se registraron y evaluaron por análisis de varianza multifactorial mientras que la mortalidad al nacer y en la lactancia se evaluaron por prueba de Mann-Whitney. Ninguno de los parámetros evaluados de la camada al nacer y al destete, presentaron diferencias estadísticamente significativas entre los grupos aloinmunizados y el grupo control (p > 0,05). La enteritis mostro tendencia a ser mayor causa de mortalidad en lactancia (p = 0,053). La mortalidad presento tendencia a ser mayor en los lechones de las cerdas aloinmunizadas (p = 0,12). Los resultados sugieren que la terapia con linfocitos alogénicos, administrada en cerdas gestante de primera, segunda o tercera gestación, no afecta la mortalidad predestete de la subsecuente camada.

Resumen En este trabajo, se estudiaron 506 lechones de una granja núcleo colombiana, con el objeto de determinar el efecto sobre el peso a los siete días de vida, de un tratamiento con un derivado comercial de calostro bovino, suministrado al primer día del nacimiento. La condición de bajo peso al nacer (BPN) afecto el peso a los siete días de vida de los lechones, los cuales pesaron significativamente menos que los lechones normales (p < 0,01). El tratamiento con el derivado comercial de calostro bovino, tuvo un fuerte efecto a los 7 días en los pesos de los animales tratados (p < 0,05). Se observó asociación entre la condición BPN y una mayor mortalidad en la primera semana de vida (p < 0,01). El suministro del derivado calostral a los lechones al primer día de vida, incremento el peso a los 7 días de los animales tratados (p < 0,05). Palabras clave: calostro, lechones, mortalidad, peso, tratamiento.  Summary 506 piglets of a Colombian nucleus farm were studied to determine the effect of an oral treatment at birth with 3cc of bovine commercial colostrum, on their weight at seven days of age. The low birth weight piglets-LBWP, had significantly less weight, tan normal weight piglets at 7 days of age (p < 0.01). The treatment had a strong effect by increasing weight at seven days of age (p < 0.05). It was found that there is association between low birth weight condition and higher mortality at the first week of life (p < 0.01). The treatment with a bovine commercial colostrum was effective, specially on the LBWP at seven days of age (p < 0.05). Keywords: colostrum, mortality, piglets, treatment, weight.
Un enfoque genético de la mortalidad prenatal en porcinos
Authors: Henao Francisco , Hernández Aureliano
Published: August 2024

Resumen El cerdo aporta 40% de la carne producida en el mundo y 5,4% del producto interno bruto pecuario colombiano (PIBP; casi US$ 500.000,000). El tamaño de camada al nacimiento (TCN) afecta considerablemente el rendimiento de la empresa porcina, dado que su mejoramiento puede reducir más los costos de producción que el de tasa de crecimiento, edad a la pubertad o relación carne-grasa. El TCN tiene heredabilidad relativamente baja, es afectado drásticamente por la endocría y se mejora mediante exocría. La investigación en esta área ha indagado sobre ventajas comparativas evidenciadas por genotipos como el Meishan y se ha establecido que su superioridad en TCN está en buena parte determinada por una menor mortalidad prenatal. El ambiente uterino Meishan induce menor producción de 17 b-estradiol de origen trofoblástico, mayor vascularización y menor desarrollo placentario, en tanto que el desarrollo del conceptus es afectado significativamente por la interacción entre su genotipo y el ambiente uterino. Palabras clave: cerdo, mortalidad prenatal, Meishan. Summary Pigs generate 40% of meat produced worldwide and represent 5.4% of the Colombian GNP (almost US$ 500.000.000). Litter size at birth (LSB) substantially influences profitability in the swine industry because its improvement reduces production costs more than the improvement of growth rate, age at puberty and lean-fat ratio. The LSB has a relatively low heredability but is affected drastically by inbreeding and is improved through crossbreeding. Research in this field has investigated the comparative advantages shown by breeds such as the Meishan. It has been established that Meishan superiority in LSB is due to a large extent to a lower prenatal mortality. The Meishan uterine environment induces lower 17 b- estradiol production from the trophoblast and the production of a smaller highly vascularized placenta while the conceptus development is highly influenced by the genotype-uterine environment interaction. Keywords: Meishan, pigs, pretantal mortality.
Factores fisiológicos que modifican la acción de los fármacos en medicina veterinaria
Authors: Ruiz B. Jhon D.
Published: August 2024

Resumen Son numerosos los aspectos que se deben tener en cuenta al momento de prescribir medicamentos, más aún en Medicina Veterinaria, debido a las diferencias entre especies y, por lo tanto, a los diferentes mecanismos fisiológicos que esto implica. La mayoría de las diferencias entre las especies pueden ser explicadas en un buen número por diferencias farmacocinéticas (absorción, metabolismo, distribución y excreción del medicamento) y unas pocas, solo por fenómenos farmacodinámicos; las diferencias entre razas son menos frecuentes, y aunque no todas han sido explicadas satisfactoriamente, la farmacocinética explica muchas de estas. Las diferencias entre individuos, sexo, hábitos dietéticos, peso y condición corporal son más conocidos por los clínicos y explicados de manera similar en la medicina humana. Todo este panorama exige que se deba conocer la farmacología de los medicamentos en cada especie, ya que las posibles extrapolaciones de una especie a otra son irracionales y llevan a correr riesgos innecesarios. Palabras clave: edad, especie, farmacocinética, farmacología, fisiología, medicamentos, raza, sexo. Summary There are many topics should be consider to prescribe medicaments, even though, in the practice of veterinary medicine, issue of the species differences and then, the differents physiological mechanisms. Majority differences can be explain by pharmacokinetics differences (absorption, metabolism, distribution and excretion of medicaments) and a few, by pharmacodinamics phenomens; the differences between breeds, are less frequent, although all of them have not been explain satisfactory, the pharmacokinetic explain mostly of them. The differences between individuals, sex, nutritional habits, weight and corporal condition are more familiar by practitioner veterinary and they are explain in a similar way to the human medicine. This situation demands of medicaments pharmacology a complete knowledge, for each specie, because possible extrapolation from one specie to another one is irrational and could be risky.

Resumen El ganado Blanco Orejinegro descendiente del ganado traído por Colón durante su segundo viaje, ha sobrevivido durante casi 500 años en las áreas tropicales colombianas productoras de café. Además de su capacidad adaptativa este ganado ha mostrado otras características como: docilidad, habilidad para aprovechar forrajes de mala calidad, gran habilidad materna, mayor precocidad sexual, alta fertilidad, mayor productividad en cruces F1 (carne y leche) y marcada resistencia a ectoparásitos. Estas características, en conjunto con hallazgos moleculares recientes que sugieren alta variabilidad genética y resistencia a patógenos bacterianos y vírales demuestran que esta raza, que en la actualidad se encuentra en vía de extinción, es portadora de información genética importante que la convierte en una alternativa para la producción en las condiciones tropicales. El objetivo de esta revisión es hacer una recopilación de trabajos realizados con ganado BON; además, mostrar las perspectivas de investigación, basados en los trabajos actualmente llevados a cabo en la Universidad de Antioquia, con el fin de demostrar el potencial genético de esta raza, que quizás no ha podido ser expresado debido a las condiciones de manejo a que esta raza ha sido sometida. Palabras Clave: ganado criollo, Blanco Orejinegro (BON ). Summary BON cattle derived from the domestic animals brought by Christopher Columbus on his second trip have gone through 500 years of adaptation to the tropical coffee producing areas of Colombia. This breed posseses several important characteristics such as: tameness, maternal ability, longevity, high fertility, increased productivity in F1 crosses, and ability to take advantage of rough relatively poor pastures. These qualities together with recent molecular findings suggesting high genetic variability and resistance to viral and bacterial infections make of this breed, now classified as "at risk" of extinction, an invaluable genetic resource from which a national cattle industry adapted to our tropical conditions could be established. The aim of this review it is to compile information about this breed and indicate some research perspectives to the light of advances made at University of Antioquia demonstrating the genetic potential of this breed, that maybe has not been expressed before due to the husbandry conditions to which it has been subjected throughout the five centuries. Key words: Black-ear White cattle, native cattle.

Static and dynamic influence of forces on a being threshed corncob
Authors: Poghosyan Vladimir M. , Poluektov Alexander A.
Published: August 2024

BACKGROUND: With the use of high-speed shooting, it was found that the corncob, getting into the gap of the threshing unit, generally, takes a position parallel to the drum axis. Let us accept that the plane of operation of the working body of the threshing drum – the beater – coincides with the generatrix of a cob. The cob changes the motion mode because of the impact of the threshing machine beater on the cob. The impact can take place in the moment when the cob even does not hit the deck cleats, so the cob gets a flying kick.
AIM: Deriving the static and dynamic influence of forces on the being threshed corncob. Defining the necessary force of corn seeds breaking-off from the cob in dependence on the friction coefficient.
METHODS: The value of mechanical impact of working bodies of the orienting-metering loading device and the threshing-separating device on a corn seed is limited not only by strength properties of the protecting corn cover, but by the link strength between a seed and a cob in the nose, middle and root areas. Knowledge of this mechanical-technological property helps to increase the level of variability of force impact in corncobs from the side of working bodies of the used machinery. It helps to transport the corncobs without husk, to orient them in space, to supply in small increments for the proper processing and, in addition, to thresh without causing any macro- and microdamages to the seeds.
RESULTS: The seed moisture change and, consequently, the seed-to-seed friction coefficient change also influences on the ratio between the applied force P and the reacting force N. With the same load P applied to the dry and the moisty cobs, the pressure N on the dry seed is higher than on the moisty one, and seed threshing from the dry cobs is conducted with lower external forces P at free direct impact.
CONCLUSION: The process of the flying kick threshing becomes more difficult with the increase of corncobs moisture due to increase of seed-to-seed friction. The flying kick threshing of corncobs stops at the seed moisture which corresponds to the friction coefficient f = 0.22. The obtained theoretical principles are confirmed experimentally.

How viruses spread across space and time: forecasting pandemic progression by modelling geographico-temporal interactions
Authors: Chang HaoRan , Grasse Lukas , Kaushik Yagika , Sade Sally
Published: August 2024

The COVID-19 pandemic has revealed severe flaws in the global healthcare systems ability to respond to unexpected health catastrophes. Much of the confusion and mishandling of the situation could be attributed to the failure in accurately predicting the spread of the virus across geographical locations. A global resource shortage in essential medical supplies and equipment, such as personal protective equipment (PPE) and ventilators, led to a compromised global supply chain. As a result, resources could not be allocated as needed to curb the spread of the pathogen in the most efficacious way. Although forecast models and machine learning algorithms have served as invaluable tools in devising effective response strategies, a large majority of these models were limited by their ability to describe the intricate interactions that underlie the spatio-temporal dynamics of viral proliferation. To address this issue, we employed a vector autoregression model to help capture the evolution of the disease across both the spatial and the temporal axes. Unlike traditional autoregression models, the present model is able to account for statistical regularities that exist both within a given region, and between geographical locations. Our results demonstrate that this approach accurately described the relationships across domestic and international localities throughout the evolution of the disease.
Natural Language Processing for Automated Customer Service in Banking
Authors: Mohammed Manzoor Anwar
Published: August 2024

NLP integration into automated banking customer care systems is examined for its effects on customer experience and operational efficiency. The main goals are to assess NLP's effects on customer happiness, reaction times, and accuracy and identify its limits. Secondary data compares satisfaction levels, response times, and mistake rates before and after NLP's implementation. NLP enhances customer satisfaction and operational efficiency, particularly for routine queries and transactions. Complex problems and technical aid need human intervention, making management challenging. Privacy and data security are also important. Policy implications advise strong data security and a balanced strategy combining automated and human help to answer complex inquiries. NLP can improve banking customer service. However, the research suggests more development and deliberate policy implementation.

CONECTIVOS INTUICIONISTAS SOBRE ESPACIOS TOPOLOGICOS
Authors: Caicedo Xavier
Published: August 2024

El clasificador de subobjetos de un topos constituye su "objeto de valores de verdad" y sus morfismos determinan los conectivos proposicionales de su lógica interna. Continuando trabajo anterior para modelos de Kripke, estudiamos dichos conectivos para la lógica de los haces sobre espacios topológicos, caso en el cual están totalmente determinados por ciertas operaciones en conjuntos abiertos. Los conectivos monádicos junto con los de Heyting forman una familia "funcionalmente" completa en cualquier topos espacial; en particular, un solo conectivo adicional genera los implícitos en la lógica trivalente de Heyting. Damos una axiomatización completa para la lógica intermedia modal que resulta en este último caso. Analizamos también los conectivos invariantes bajo homeomorfismos locales, y la escogencia global y uniforme de conectivos en distintos espacios. Los resultados principales se pueden generalizar inmediatamente a los topos de haces sobre álgebras de Heyting completas.

Modelaciones hidrológicas e hidráulicas se realizaron simultáneamente en Iber planteando diversos escenarios hidrológicos para tres alternativas de gestión natural de inundaciones a saber: (1a) dar espacio al cauce eliminando las contracciones y limitaciones generadas por estructuras tipo puentes, (2a) cambiar la cobertura vegetal de la parte alta de la cuenca, aumentando la rugosidad e infiltración del suelo y (3a) reconectar el cauce con sus llanuras de inundación permitiendo que allí disipe flujos y energía. Aplicar dichas estrategias, las simulaciones resultaron en la disminución de caudales punta y retraso en los tiempos pico en los hidrogramas, por lo que se puede concluir que, a partir este tipo de soluciones de rehabilitación del cuerpo hídrico, es posible mitigar el riesgo por inundaciones logrando un beneficio a largo plazo.

Objetivo: analizar los cambios en la dinámica de la inflación de Argentina entre los años 2004 y 2020. Metodología: se utiliza el filtro de Kalman con el objeto de estimar la relación entre las variables bajo estudio identificando a través de la evolución en el tiempo de los coeficientes estimados, cuáles de ellas permiten explicar el comportamiento de los procesos inflacionarios de Argentina. Resultados: los coeficientes estimados presentan fluctuaciones a través del tiempo. El tipo de cambio y la inercia inflacionaria son las variables con mayor incidencia. Limitaciones: el filtro de Kalman soluciona un problema en la estimación de parámetros no estables en el tiempo, pero no es posible hablar estrictamente de determinantes de la inflación sino de cambios en la dinámica inflacionaria. Originalidad: en línea con algunos estudios contemporáneos, se comprueba que la inflación argentina puede ser explicada por diversas variables. Conclusiones: el estudio permite conocer la influencia de distintas variables en los recurrentes procesos inflacionarios de Argentina, identificando la importancia de cada una de ellas en la explicación del fenómeno.

Literacy skills are a manifestation of an individual’s ability or quality of being literate, encompassing the ability to read and write, both physically, tactically, and technically, within a unit to carry out a mission or task. In this case, the mission is to enhance the reading interest of elementary school students in the Cilengkrang District, Bandung Regency. In line with Cope and Kalantzis (2000), multiliteracy pedagogy has evolved to encompass multilingual and multimodal dimensions of literacy[1]. This has implications for schools and communities that need to develop practices and skills in using various ways to express and comprehend ideas and information through conventional text forms as well as innovative text forms, symbols, and multimedia [2]. Literacy skills can be enhanced by adapting current learning media to be digitally based to attract the literacy interest of students. Through engaging learning media, the literacy movement can be successful. The method used is digitizing conventional learning media and introducing innovative new learning media to enhance reading interest in students. Based on these considerations, training on creating digital-based learning media is necessary as an innovative effort in preparing effective learning media with the goal of improving the literacy skills of elementary school students. The training, followed by mentoring, will be conducted over a three-month period, from February to April 2023, involving 36 teacher participants. The outcomes of this training and mentoring, students interest in elementary schools in Cilengkrang District has increased because learning media is no longer conventional and digital based. This increase was achieved after teachers attended training and were able to create and apply digital-based learning media in the classroom.

Published: August 2024

This research aims to identify Neleng Neng Kung nursery rhyme from the perspective of a child’s well being. Child well-being is currently facing threats due to several factors, mainly the crisis of dominant values from modernization (identically to the westernization). Adding to the factor is the change in the current Western dominance in science and knowledge. In the child well-being context, each ethnic group has childcare traditions, specifically for nursery rhymes. Various studies have touched on this subject, but none of them relate to child well-being. Therefore, this study aims to cover the relation of Neleng Neng Kung as a nursery rhyme with child well being. This research uses the Norman Fairclough model of Critical Discourse Analysis, which includes three steps: description, interpretation, and explanation, and the UNICEF framework for child well being. The conclusion shows that the local wisdom covers a part of the child well-being framework and centers well-being to social relations. Physical and intellectual aspects must be guided by social ones.

Mother plays an important figure in a child’s life. Children can learn various things from their mothers, so, naturally, mothers have a bigger role in introducing Islamic values into children’s lives. This research aims to find the right way to foster Al-Quran literacy in children’s mothers. This research uses a quantitative approach with a quasi-experimental method. The research participants were mothers who had primary education and young children. The research results proved that the experimental class gain was 0.522 or was in the medium category, higher than the control group. This explains that continuous training can improve the understanding and skills of mothers with basic education.
