Por una historia receptiva del intelectual y sus textos en contexto
Authors: Zapata de la Cruz Jenny
Published: October 2024

El escrito parte de una revisión historiográfica sobre la historia intelectual impulsada desde la Argentina (matizándola con algunas propuestas de historiadores en México), la cual ha imperado en el continente en las dos últimas décadas del siglo XXI. El estudio que aquí se expone muestra los rumbos elegidos por los historiadores después del giro lingüístico y la necesidad de diferenciar la historia intelectual de la historia de las ideas; de allí se han derivado dos propósitos, el primero, reflexionar las categorías conceptuales: intelectual, texto y contexto. En este sentido, me permití exponer posibles usos de estos dos últimos conceptos para la pesquisa archivística y la elección del tipo de fuentes para la comprensión del intelectual y sus textos. El segundo objetivo consistió en plantear la naturaleza y características del intelectual, mostrando las contradicciones del discurso en el texto.
El artículo cierra con las preocupaciones de cómo aprehender a los intelectuales por medio de su contexto público e íntimo (personal), que involucran sus acciones sociales, políticas y culturales, mostrando la importancia de la interdisciplinaridad de la cual se reviste la historia intelectual hoy.
El exilio brasileño y el 68 mexicano
Authors: Morales Muñoz Daniela
Published: October 2024

En el presente artículo se exponen dos casos en los que integrantes de la comunidad de exiliados brasileños en México fueron afectados por la represión estatal que se ejerció  en torno al movimiento estudiantil y popular de 1968. Se trata de proponer una mirada hacia dichos acontecimientos represivos que no sólo se interrogue por las consecuencias de la represión en términos cuantitativos sino que, además, se proponga indagar en aspectos cualitativos que puedan ayudar a develar otros aspectos en torno a ella, como podía ser, develar la identidad de muchas victimas que hasta ahora han permanecido sin rostro.
actualidad de la filosofía como filosofía social
Authors: Kozlarek Oliver
Published: October 2024

El artículo aboga a favor de una filosofía que se entiende a sí misma principalmente como filosofía social. Se trata de una filosofía que se caracteriza por un compromiso con la sociedad en dos sentidos: por un lado, se trata de un compromiso con un concepto normativo de sociedad, que representa un contrapoder frente al Estado. Por otro lado, es un concepto de sociedad que siempre es también un lugar de crisis. En este contexto, filosofía como filosofía social debe entenderse como administradora de crisis. El artículo pretende mostrar que esta comprensión se expresa sobre todo en la tradición de la Teoría Crítica, pero también que las versiones actuales de esta tradición carecen de un concepto normativamente sustantivo de la sociedad.

Authors: Acuña Neave Claudia
Published: October 2024

El uso de dispositivos móviles es de suma importancia en el día a día, de tal forma que parecieran incluso estar adheridos a nuestro cuerpo, pues nos ayudan a comunicarnos con quienes no están presentes de forma física frente a nosotros, pero a su vez fomentan que nuestra atención se centre en una situación ajena al momento. Por ello, las repercusiones en las personas que padecen TDAH, pueden estar relacionadas al tiempo excesivo a la exposición a pantallas digitales, influyendo en acciones de su vida cotidiana de manera negativa o en el ámbito cognitivo, conductual y emocional tanto a nivel personal y social, de ahí que sea importante saber cuánto es favorable para las personas utilizar las pantallas electrónicas, así como el contenido multimedia (videos, audios, videojuegos, programas de televisión, etc.) a los que accede.

Published: October 2024

La evolución de las tecnologías de la información y comunicación y su uso ha cambiado la forma como las personas interactuamos y como nos desenvolvemos en diversos aspectos de nuestras vidas, tales como los negocios, la publicidad, educación, así como también en áreas de nuestra salud física y mental.  Lamentablemente como en muchos otros casos, estas nuevas herramientas que inicialmente suenan beneficiosas y que generan cambios positivos, se comienzan a distorsionar por el uso excesivo o por el uso inadecuado de los estudiantes universitarios y por consiguiente conllevan a afectaciones que van desde lo mental como el estrés, ansiedad, acoso a lo físico con los trastorno de la imagen, bulimia, anorexia, accidentes y en los extremos más indeseables hasta la perdida de la vida de algunos usuarios dado que hay sitios que facilitan y favorecen la ideación suicida dentro de sus contenidos. Por tal motivo es evidente que los países, las empresas e inclusive usuarios generen políticas adecuadas para el uso, supervisión e inclusive una programación de los tiempos que se destinarán para interacción con estas plataformas y las cuales propicien un uso más saludable de las mismas.
Comunicar la ciencia: ¿difundir o divulgar?
Authors: Herrera-López Gabriel
Published: October 2024

La comunicación de la ciencia tiene varios matices, dos de los más más grandes son los que se definen alrededor de los conceptos difundir y divulgar. Es común que creemos que hacemos divulgación cuando en verdad estamos haciendo difusión. Las diferencias radican en el público al que se dirige el mensaje y la forma en que se diseña el discurso. Mientras que la difusión es un proceso de comunicación de la ciencia entre pares, la divulgación se dirige hacia un público inexperto evitando el uso de términos especializados y aprovechando recursos literarios como la narrativa. Es necesario conocer las características propias de la divulgación para generar un producto que cuente con impacto social.

Authors: L Sowmiya , S M Ramesh , Shadrach S Finney Daniel , A Arul
Published: October 2024

Adders play a critical role as primary modules in circuit design, supporting error-tolerant applications such as machine learning, digital image processing, and signal processing. Therefore, the development of adders with low power consumption and energy efficiency is of utmost importance. Approximate adders outperform exact adders in VLSI chips. Among approximate adders, the hybridization of Single Exact and Single Approximation (SESA) and Single Exact and Dual Approximation (SEDA) techniques has emerged as a promising solution. These hybrid adders offer superior power and energy savings relative to other accurate and approximate adder designs. In this scheme, we propose the integration of hybrid radix-4 adders with approximation adders to achieve enhanced performance and pave the way for future hybrid approximate adder circuits. Extensive simulations validated the efficacy of the proposed approach. Furthermore, practical applications demonstrated the versatility and potential of hybrid adders in real-world scenarios. The proposed methodology ensures cost-effectiveness and facilitates seamless future updates and extensions. Overall, this research contributes to the advancement of efficient and low-power adder designs, addressing the evolving requirements of modern digital systems.

Infectious diseases of bees and their impact on the vital activity and honey productivity of honey bee colonies in Ukraine
Authors: Sumakova N. V. , Sanin Yu. K. , Keleberda M. I. , Rudenko Ye. V. , Nikiforova O. V.
Published: October 2024

The article presents the results of the study of the mass mortality of honey bee colonies in different apiaries from different regions of Ukraine. The epizootic status of 102 honey bee colonies was studied and 607 samples of pathological material were analyzed in 2021–2023. According to the results of the monitoring of the epizootic situation in Ukrainian beekeeping it was found that the share of parasitic diseases (54.4%, 74.0%, 69.3%) constantly prevails over infectious diseases. It was noted that the incidence of varroosis in honey bees (34.4%, 71.4%, 41.47%) remains the highest among other diseases. Against the background of severe damage to honey bee colonies by the Varroa mite, infectious diseases began to appear in an atypical form, which significantly complicates their differential diagnosis. A probable increase in the incidence of nosemosis in adult bees and the detection of Nosema cysts in the intestines of bees, both in spring and summer, and the detection of cysts in honey indicate the spread of another pathogen, Nosema cerana, which causes nosemosis in the summer season. The reason for the periodic mass death of bees in Ukraine is the combination of a high number of parasitic Varroa mites in the honey bee colony with the presence of bee infection with microsporidia Nosema spp. These pathogens negatively affect the immunity of the honey bee colony, and cause exacerbation of latent infections in bees, which leads to a decrease in the number of honey bee colonies, weakening their viability and reducing the quality of honey products

The study aimed to evaluate the epizootic status of livestock in Ukraine concerning the prevalence of bovine immunodeficiency virus and bovine foamy virus infections. A literature review was conducted to analyze the epizootic status of livestock farming in various countries regarding bovine immunodeficiency and spumavirus infections. To investigate this issue in Ukrainian livestock, blood samples were collected from 10–15 cows with further DNA extraction and studies via PCR, according to the developers’ recommendations. The biological characteristics of bovine foamy virus and bovine immunodeficiency virus were studied by infecting bovine fetal lung (LEK) and calf coronary vessels (KST) cell cultures, with each passage being visually monitored and examined through light microscopy. PCR was performed on the third and fifth passages to detect the genetic material. The genetic material of bovine leukemia virus, bovine immunodeficiency virus, and bovine foamy virus was confirmed in 12 farms across 8 regions of Ukraine. It was demonstrated that bovine immunodeficiency virus and bovine foamy virus can integrate into homologous cell cultures derived from cattle. The immunosuppressive effects of bovine foamy virus and its capability to inhibit components of the non-specific immune system were established on laboratory animal models. Emphasis is placed on the necessity to develop domestic tools for the retrospective diagnosis of bovine immunodeficiency and spumavirus infections and to implement a national anti-epizootic program

The article provides a brief historical background of equine influenza, the spread of this disease worldwide, and the current epizootic situation. The results of serological monitoring by ELISA of wild and domestic ungulates from different farms and regions of Ukraine for the presence of antibodies to influenza A viruses are presented. Blood serum samples from 372 domestic horses and 32 wild ungulates were tested. Samples from animals collected in 2023 and 2024 and archival blood serum samples from 2021 were used and tested according to the manufacturer’s instructions using ELISA test systems manufactured by IDEXX, INGEZIM, and IDVet. The data obtained indicate a fairly active circulation of influenza A viruses in populations of unvaccinated domestic horses. The circulation was established not only in recent years (2023–2024, seroprevalence from 10% to 100%), but was observed earlier, as evidenced by the detection of 60.9% of positive samples in samples collected in 2021. In addition, two out of three positive samples were found in wild horses from Kherson Region, which indicates the circulation of influenza A virus among wild animals and requires further investigation. The results correlate with the worsening of the epidemiological situation regarding influenza in animals in Europe. The subsequent phase of the research is serotyping, which involves determining the presence of antibodies to specific virus subtypes by hemagglutinin

Published: October 2024

The shortage of raw materials in the automobile industry has had a significant impact on the manufacturing process, leading to disruptions at multiple levels. With key materials such as semiconductors, steel, and aluminum in short supply, manufacturers have faced delays in production schedules, increased costs, and inefficiencies in supply chain management. This shortage has also forced many companies to adjust their production strategies, often by scaling down output or prioritizing certain models, which can lead to bottlenecks in delivering products to the market. Moreover, the scarcity of raw materials drives up procurement costs, further squeezing profit margins for automobile manufacturers. The long-term effects of this shortage may include shifts towards more sustainable and alternative materials, as well as greater investment in localized supply chains to reduce dependency on global sources. Ultimately, the raw material shortage poses a challenge to both the operational efficiency and the competitive edge of the automobile industry.

Authors: - Akshat Bhutiani
Published: October 2024

This paper proposes an optimal approach for real-time defect detection in industrial assembly lines using Convolutional Neural Networks (CNN’s) implemented on ARM Cortex – M microcontrollers. Although CNNs are very accurate when detecting visual defects, their computational complexity makes them difficult to implement on devices with limited resources. To address this issue, techniques such as model pruning, quantization and memory optimizations tailored to the ARM Cortex -M microcontroller will be used. This results in an average inference time of 80-100 ms per image and the system achieves 92% accuracy which makes it suitable for industrial applications.

Published: October 2024

This research was about facilitating students’ pronunciations on plosive consonant sounds through Sephonics software. It was done at 3rd semester students of ELT Department of Walisongo State Institute for Islamic Studies in the academic year of 2011/2012. The background of this research was the difficulty in learning pronunciation. This research was aimed to responding the following questions; (1) How was the implementation of using sephonics software for teaching pronunciation (plosive consonant sounds) at third semester students of ELT Department, State Islamic Institute of Walisongo, Semarang? (2) Was there any improvement of students’ pronunciation of plosive consonant sounds after being taught using sephonics software? The participant of this research was the 3rd semester students of ELT Department of Education Faculty, Walisongo State Institute for Islamic Studies, Semarang that consisted of 28 students. It was a classroom action research that had two cycles. They were pre-cycle, cycle 1, and cycle 2. The use of sephonics software was used in cycle 1 and cycle 2. The methods of data collection were test and observation in all cycles. The test form was reading aloud that asked students to pronounce some words that contained plosive consonant sounds. Then, the result of test scores was analyzed by using mean to determine whether there was an improvement in each cycle.
This study showed that: (1) the first thing that the teacher needed to do to use this software as a teaching aid was that he or she must conduct the class in a language laboratory. If it was not possible, the teacher could conduct the class in a regular classroom by providing several computers or laptops. Then, the students must be grouped based on the number of the computers. The second thing was that this was CALL learning based; the teacher might explain how to use the software in order that the students could practice by themselves outside of class schedule. (2) After collecting data, the result was found that the average (mean) of pre cycle test was 69. Then, it had very significant improvement in cycle 1 and cycle 2. It became 98.7 from cycle 1 test and 99.6 from cycle 2 test. It meant that the research was successful to improve the students’ pronunciation abilities. In conclusion, Sephonics software was successful to facilitate students’ pronunciations on plosive consonant sounds.

Objective: Emergency departments (ED) are critical to the United States healthcare system. However, they are known to be inefficient environments to deliver definitive care including management of dental emergencies. ED’s may also serve as an inadvertent, but important, stop gap for individuals who lack dental coverage. The nation’s healthcare system continues to struggle with inadequate resources to provide dental care for vulnerable patients who disproportionately suffer from dental-related conditions. Method: This study is an analysis on dental-related ED utilization in the state of Michigan. The authors collaborated with the Michigan Health & Hospital Association who provided data from the Michigan Inpatient and Outpatient Database for dental-related hospital emergency department (ED) visits in Michigan hospitals during 2018-2019. University of Michigan Medical School’s committee on human subjects’ research reviewed the protocol and provided IRB exemption (HUM00192629). Results: State funded Medicaid (33%) and federally funded Medicare (33%) were the most common payer types for patients with dental-related conditions who reported to Michigan ED’s from 2018 to 2019. Charges per ED encounter was the highest for Medicare, $2,900-$3,200, and lowest for other payers, $1,300-$1,500. Charges for ED-inpatient per encounter were the highest for Medicare ($22,000-$24,000). The age range for which patients most frequently presented to the emergency department (ED) was 25-64. However, expenses per encounter for patients 65 and older were roughly two to three times higher than for patients in other age ranges. Conclusion: The study revealed a disproportionately higher percentage of patients who identified as Black presented to Michigan emergency departments (30%) with a dental-related emergency.

Aim: The purpose of this study was to digitally quantify the consistency and variation of printed resin crown patterns produced by different 3D printers, aiming to evaluate their clinical relevance and accuracy. This was accomplished by evaluating patterns manufactured using three different 3D printers and resin materials, assessing their fit and adaptation through digital scanning and analysis. The objective was to determine the internal and marginal variations of printed crown resin patterns and to identify the printer and material combinations that produce the most consistent and clinically acceptable results. Methods: A prefabricated typodont tooth was prepared for a crown and scanned using an intraoral scanner. From this scan, a crown was designed and the resulting STL file was exported. This 3D file was manufactured using resins indicated for castable patterns on 3 different printers: FotoDent® Cast with the Carbon M2 printer, Form 3 Castable with the Form 2 printer, and Siraya Tech Cast with the ELEGOO Mars 2 Pro 3D printer. Finally, the crown resin patterns were scanned using an intraoral digital scanner (3Shape TRIOS 3) scanner, and crown adaptation was digitally quantified in GeoMagic software. Clinically relevant significance was determined (marginal gap < 50 µm) between resin patterns printed on different printers. Results: Form 3 Castable/Form 2 printer had the lowest mean internal variation at all measurement areas, 21.07 μm at the occlusal, 104.23 μm at the margin, and 37.98 μm at the axial. FotoDent® Cast/Carbon M2 had the largest marginal variation while Siraya Tech Cast/ELEGOO Mars 2 Pro had the largest occlusal variation. Within each material, the largest internal variation was at the marginal area while the lowest value was in the occlusal area.
Conclusions: All printed crowns displayed clinically acceptable ranges, but there was a statistically significant difference in the fit between all printers.
Hepatitis B virus: modes of transmission, immune pathogenesis, and research progress on therapeutic vaccines
Authors: Li Chunzheng , Wei Chenyu , Yang Xianguang
Published: October 2024

Hepatitis B virus (HBV) infection affects 262 million people worldwide, leading to over 820,000 deaths annually. The reason HBV has been a persistent issue for decades is that it is a non-cytopathic, liver-specific virus with the ability for persistent infection, which cannot be completely eliminated by drugs, eventually progressing to cirrhosis and hepatocellular carcinoma (HCC). Although HBV seems to induce little innate immune activation, adaptive immune responses can mediate viral clearance and liver disease. Here, we review the epidemiology, natural history, lifecycle, and modes of transmission of HBV. We also pay particular attention to the adaptive and innate immune responses to HBV and the research progress on therapeutic vaccines, which may provide new insights for targeted HBV treatment.

Published: October 2024

This research seeks to evaluate how effectively seizures can be predicted and managed in epilepsy using a specialized deep learning model based on Long Short-Term Memory (LSTM) neural networks. The model leverages non-invasive scalp electroencephalography (EEG) recordings for predicting seizures. To develop and assess the proposed LSTM neural network model, a comprehensive dataset was gathered. The model emphasizes achieving high sensitivity and reducing false alarms to improve its real-time applicability. The evaluation involved various metrics to measure accuracy, sensitivity, and rates of false positives and false negatives. The effectiveness of the proposed LSTM neural network model was outstanding, with accuracy rates ranging from 99.07% to 99.95%. Notably, the sensitivity score of 1 confirmed precise prediction for all seizure cases. The model demonstrated minimal false positive and false negative rates, highlighting its reliability in predicting seizures. This study emphasizes the promising potential of the proposed LSTM neural network model in providing advanced warning for seizures. The high accuracy and sensitivity rates suggest its usefulness in enabling timely preventive measures for patients, ultimately reducing the occurrence of seizures. This innovative approach holds significance in enhancing the overall management and quality of life for individuals dealing with epilepsy.

The article presents the results of the study and use of modified zeolite-containing catalysts (ZSM-5) and natural alumosilicates (halloisite) in the process of alkylation of distillate fraction with catalytic cracking gases. Based on thermogravimetric analysis, it was determined that modification of halloisite with the Al+CCl4 system leads to the appearance of peaks indicating exo- and endo processes under the influence of temperature. When the oil fraction was alkylated at a temperature of 50 oC on Al+CCl4+halloisite catalyst with catalytic cracking gases containing olefins of 43.47 % the viscosity index was increased from 32 to 84. Based on NMR spectra, it was determined that alkylates differ from the original oil fraction by increased values isoparaffin index, the number of protons in aromatic structures and those furthes from the aromatic nucleus. These data confirm the improvement in the viscosity temperature characteristics of the oil fraction. Alkylation of an oil fraction with a viscosity index of 49.9 on ZSM-5 and ZSM-5-ZrO2 catalysts made it possible to obtain oils with a viscosity index of 80.7 and 137, respectively. Based on X-ray diffraction studies using rentgenographic method, it was shown that Zr is contained in the structure of ZSM-5 zeolite in the form of ZrO2. The introduction of Zr into the crystaline structure of the zeolite helps to increase the activity of the modified catalyst ZSM-5-ZrO2. Research has shown that the phase composition of samples of the modified ZSM-5-ZrO2 zeolite changes depending on the calcination temperature. An increase in temperature from 200 to 550 oC leads to the transition of the amorphous phase to the crystalline phase, and at a given calcination temperature a phase belonging to ZrO2 appears. The introduction of Zr into the catalyst composition leads to a change in the ratio of the Lewis and Brensted acid sites of the ZSM-5 catalyst. Namely, there is an increased Lewis and a decreased Brensted acid sites. Based on this it can be assumed that both Brensted and Lewis acid sites take part in the alkylation process.

Currently, sucker-rod pumping (SRP) units are widely used in oil wells, due to two important factors: costs and ease of use. To optimize production using sucker rod pumps, well Rod Pump Controllers (RPC) have been used for more than 20 years. Today the main method of controlling the sucker-rod pumping unit is the analysis of dynagraph card (determination of the state and mode of operation of the pump based on the dependence of the rod’s load on its position). The qualitative analysis of a dynagraph (DMG) comes down to diagnostics, which detects and identifies signs of possible malfunctions of the pump and the well as a whole. The task of determining malfunctions by a dynagraph is considered difficult for a computer analysis and involves the evaluation of a dynagraph card by a qualified technologist. This article discusses methods and algorithms for determining malfunctions from obtained RPC dynagraphs, implemented directly on base of the well controller. These methods can be divided into analytical and neural network methods. Analytical algorithms describe the DMG defect in the form of formulas or logical dependencies. Neural network methods approach the problem of defect recognition as recognizing a set of unrelated data. This helps to work with a system with a large number of parameters, such as a (SRP). The Naftamatika took into account the pros and cons of previous approaches and developed its own neural network model. The development consisted of selecting the type of network, the number of its layers, creating a spatial structure of neurons, creating conditions for training the network and selecting an adequate training sample. To train the controller, a program was used in which thousands of dynamograms with various defects and conditions were loaded. This network model is implemented in a Wellsim pump controller, which provides sufficient performance, the algorithm successfully detects insufficient filling, gas factor and other faults with an accuracy of 96 %.
