Critical discourse analysis of a film about marriage which is motivated by the concept of primogeniture becomes an interesting discourse to be studied. This study aims to analyze the concept of marriage from the point of view of the female character in the film Pride and Prejudice (2005) by using the critical discourse analysis method according to Norman Fairclough. This research is an explanatory research with a qualitative approach. The analysis was carried out through three stages, namely microstructural, mesostructural, and macrostructural analysis. From the research it was found that the perspective of each female character regarding marriage in the film Pride and Prejudice (2005) is influenced by two main things, namely the character's personal character and the character's living conditions according to the storyline. Jane Austen has the power to convey her ideology regarding primogeniture issues that occurred in society in her time to convey to readers through her novel Pride and Prejudice which director Joe Wright turned it into a film in 2005. Based on the results of the study, it can be concluded that marriage is influenced by Personal characters and living conditions in such a way shape the views and/or motives for the marriage of the female character in the film Pride and Prejudice (2005). Primogeniture is a factor of living conditions that most influence the perception of marriage in female characters in the film Pride and Prejudice (2005). The main problem in this storyline is related to the marriage of female characters, namely pride and prejudice.

Authors: Salsabila Cynthia Yanda , Sajarwa Sajarwa
Published: July 2024

One of the salient problems in translation arises when it comes to translation of cultural words or terms as each language may have its own set of terms. Therefore, this research deals with the orientation in translating culture-specific items from the source language to the target language. The research approach employed in this paper is descriptive qualitative. The data on culture-specific items are obtained based on Newmark’s (1988) categories and translation procedures. The obtained results indicate that the most frequently found CSI category in the data is material culture. Then, the prevailing translation procedures used to render cultural words in Ronggeng Dukuh Paruk’s novel were transference, functional equivalent, descriptive equivalent, recognized translation, componential analysis, reduction, couplets, notes and glosses. From the translation procedures conducted by translator, the orientation can be implied. The theory of translation orientation proposed by Venuti (1995) was followed. The analysis has revealed that the functional equivalent descriptive equivalent, cultural equivalent, component analysis, recognized translation, reduction, and glossary procedures are the most commonly used procedures. Thus, it implies that the translation of Indonesian CSIs in RDP into the target text orientates toward TL or domestication.

Published: July 2024

This study aims to obtain an overview of the errors in the use of ~hazu and ~beki modalities that occur in intermediate Japanese learners. This research is motivated by the similarity of the meanings of these two modalities if they are changed into Indonesian. This is what makes it difficult for students to use these two modalities. The method used in this study is a qualitative descriptive method supported by quantitative data. The instruments used were tests and questionnaires. Then, through the results of data analysis, it is known that the ~beki modality is the modality that has more errors than the ~hazu modality. It is also known that the meaning of the ~beki modality which expresses regret is the meaning of the ~beki modality which is the most prone to errors. As for the ~hazu modality, the meaning of the ~hazu modality which states a logical conclusion is the meaning of the ~hazu modality which is the most prone to errors. Furthermore, the type of alternating form error is the most common type of error that occurs in this study. This makes there is a tendency that the mistakes that occur in this middle-level learner are errors due to the respondent's competency factor.

This article analyzes the characters and characterization in the novel "Women at Zero Point" by Nawal El Saadawi using a feminist approach. This novel depicts women's struggle in facing oppression, violence and gender injustice in a patriarchal society. A feminist approach is used to analyze how the female characters in this novel face these problems and struggle to find freedom. This analysis uses a literature review method by referring to the novel "Perempuan di Titik Zero" and relevant feminist literature studies. Focus is given to the main character, Firdaus, as well as other female characters in this novel. The results of the analysis show that the female characters in this novel face oppression and violence carried out by the patriarchal system. Firdaus, as the main character, faces various forms of sexual exploitation, domestic violence, and objectification by the surrounding community. However, this novel also highlights women's solidarity as a source of strength and support in their struggle against gender injustice. A feminist approach helps in seeing how the author criticizes patriarchal norms that limit women. Firdaus and other female characters challenge narrow social expectations and attempt to shape their identities outside these constraints. In conclusion, This analysis confirms that the novel "Women at Point Zero" is a reflection of women's struggle to seek freedom and overcome gender injustice in a patriarchal society. Women's solidarity and criticism of patriarchal norms are important themes in this novel, inviting readers to consider the role and influence of patriarchy in women's lives.

Authors: Carrillo Gómez Jeniffer Katerine , Durán Acevedo Cristhian Manuel , García-Rico Ramón Ovidio
Published: July 2024

Introducción: La evaluación de la calidad del agua sigue siendo un desafío para las instituciones de salud pública en la actualidad. Una de las bacterias más abundantes y que se asocia principalmente con el riesgo sanitario del agua es Escherichia coli (E. coli). La incidencia de esta bacteria indica que existe un mayor riesgo de la presencia de otras bacterias y virus de origen fecal, muchos de los cuales son patógenos. Hoy en día, para la detección de E. coli en agua, se utilizan técnicas convencionales estandarizadas y reguladas. Estas técnicas requieren al menos 24-28 horas de incubación para la detección; además de requerir reactivos y personal calificado, entre otros requerimientos.
Objetivo: Este artículo presenta un análisis de la capacidad de los sistemas de percepción sensorial (e-nose y e-tongue) para determinar y discriminar E. coli de otras bacterias relacionada en muestras de agua.
Metodología: Para verificar la discriminación entre bacterias, se prepararon muestras de agua contaminadas con tres bacterias: E. coli, Klebsiella oxytoca y Pseudomonas aeruginosa. Como control negativo se usó agua potable esterilizada. De otra parte, para evaluar el potencial de los sistemas en estudio para la detección de E. coli en agua potable, se analizaron muestras de agua procedentes de la planta de tratamiento de agua potable (DWTP) del municipio de Toledo (N. S). Para ello, el método microbiológico usado como referencia fue el de filtración por membrana.
Resultados: La discriminación de las muestras de agua se realizó mediante el Análisis de Componentes Principales (PCA), alcanzando el 97,6% de la varianza capturada a través de la nariz electrónica. Por otro lado, con la lengua electrónica, la discriminación de la bacteria fue una variación del 99,4% en el conjunto de datos, obteniendo una respuesta similar con ambos métodos.
Conclusiones: Los resultados demostraron que la metodología propuesta permitió una evaluación efectiva entre las muestras contaminadas y las muestras de control. Se observa una excelente discriminación de las categorías para las muestras obtenidas de la planta de tratamiento de agua potable.

Published: July 2024

Introduction: In a context of global competition and technological advances, logistics has become very relevant for the proper functioning of companies, as this can represent up to 25% of the cost of goods. In this sense, vehicle routing problem solving (VRP) software is an opportunity to improve the performance of small and medium-sized enterprises (SMEs) in Argentina. In recent years, the supply of VRPs has increased significantly, although they present variants that are - a priori - difficult to discern.
Objective: To identify, characterise and compare VRP resolution software, recognising among them the most recommendable in terms of work tools and feasible to apply in SMEs, with the aim of generating a contribution to the strengthening of their distribution systems.
Methodology: The following question is defined: Which of the routing software studied and analysed are the most convenient and recommendable for small and medium-sized enterprises? Why? For the information search, the platforms Scopus, ResearchGate, GoogleAcademic, and Google were consulted. Based on a prior criteria definition, the selected software are compared and the question is answered.
Results: From the results obtained in the literature search, a number of criteria were used to select and characterise, compare and analyse the software. The six selected software were SimpliRoute, RouteXL, RoutificMain, OptimoRoute, VRP Spreadsheet Solver and ArcGIS Online.
Conclusions: The software considered most suitable are VRP Spreadsheet Solver, SimpliRoute and OptimoRoute due to their easy accessibility and ability to cover numerous decision variables. However, SimpliRoute and OptimoRoute have the disadvantage of not being free.

Authors: Escobar Pérez Alejandro , Arroyave Giraldo Karen , Lopera Cortés Jhon Anderson , Granada Torres Jhon James
Published: July 2024

Introduction/Context: The use of coherent detection jointly with high-level modulation formats such as 16 and 64-QAM seems to be a convenient strategy to increment capacity of future optical access networks. However, coherent detection requires high complexity digital signal processing to mitigate different impairments.
Objective: Mitigate signal distortions using nonsymmetrical demodulation techniques based on Machine Learning (ML) algorithms.
Methodology: First, a single channel Nyquist m-QAM system at 28 and 32 Gbps was simulated in VPIDesignSuite software. Then, different signals modulated at 16 and 64-QAM were generated with different laser linewidth, transmission distances and launch powers. Two ML algorithms were implemented to carry out the demodulation of the generated signals. The performance of the algorithms was evaluated using the bit error rate (BER) in terms of different system parameters as laser linewidth, transmission distance, launch power and modulation format.
Results: The use of ML allowed gains up to 2 dB in terms of optical signal-to-noise ratio at a BER value of  for 16-QAM and 1.5 dB for 64-QAM. Also, the use of ML showed that it is possible to use a lower cost laser (100 kHz linewidth vs 25 kHz) with a better BER performance than using conventional demodulation.
Conclusions: We showed that the use of both algorithms could mitigate nonlinear effects and could reduce computational complexity for future optical access networks.

Authors: Chaparro Velasco María Cristina , Sabater Navarro José María , Vivas Abán Óscar Andrés
Published: July 2024

Introduction: This document shows a system that simulates the illumination of the abdominal scene in laparoscopic operations using mini robots. The mini robots would be magnetically tied to the abdominal cavity and manipulated by an external robot arm. Two algorithms are tested in this system: one that moves the mini robot according to the movement of the endoscope, and another that moves from an analysis of the image captured by the scene. 
Objective: To contribute to the illumination of the surgical scene by means of mini robots attached magnetically to the abdominal cavity.
Methodology: A software tool was developed using Unity3D, which simulates the interior of the abdomen in laparoscopic operations, adding a new lighting: a mini light-type robot magnetically anchored to the abdominal wall. The mini robot has two different movements to illuminate the scene, one depends on the movement of the endoscope and the other on the image analysis performed.
Results: Tests were performed with a representation of the real environment comparing it with the tests in the built tool, obtaining similar results and showing the potential of a mini robot to provide additional lighting to the surgeon if necessary.
Conclusions: The designed algorithm allows a mini robot that is magnetically anchored in the abdominal wall to move to low-light areas following two options: a geometric relationship or movement as a result of image analysis.

Authors: González Pedraza Ana Francisca , Chiquillo Barrios Yeison Alezander , Escalante Juan Carlos
Published: July 2024

Introduction: In Colombia, 45% of the continental and insular surface presents some degree of susceptibility or propensity to soil degradation due to salinization. The high concentration of salts negatively affects the biologicals of the soil, causing a decrease in crop productivity.
Objective: The bibliographic information available on the factors associated with the salinization of soils in agricultural areas of the Caribbean region and different strategies for the recovery of saline soils was reviewed.
Method: A literature review was carried out in which the biophysical and anthropic factors of the salinization of soils and the associated consequences are documented. Additionally, a review was made of international and national scientific articles that address different strategies for the recovery of saline soils in which it was analyzed which ones have been more successful from the environmental point of view.
Results:  The salinity of the soils was related to the climatic conditions, irrigation with poor quality water, chemical fertilization, the scarce use of vegetal covers and the low contents of organic matter in the soils. Soil washing is a viable alternative if good quality water is available. The most feasible alternative was the use of organic fertilizers
Conclusions: The salinity of the soils was related to the use of irrigation water with high saline content, little plant cover, low content of organic matter in the soil and the use of fertilizers. The most viable recovery strategy is the application of organic fertilizers and amendments.

Published: July 2024

Introducción— La mora (Rubus glaucus Benth) se encuentra entre los frutales promisorios de gran importancia comercial en Colombia, y aunque se plantea que el uso de micorrizas en mora juega un papel importante en agroecosistemas sostenibles, no existe información actualizada sobre el tema.
Objetivo— Proporcionar información completa y actualizada sobre hongos micorrízicos arbusculares en interacción con especies frutales con énfasis en el cultivo de mora (Rubus sp.).
Metodología— Se realizó una investigación documental de artículos con información actualizada que indicaran el abordaje de los Hongos Micorrízicos Arbusculare­s (HMA) en zarzamora, utilizando como unidades de análisis los artículos publicados por revista­s nacionales e internacionales y las bases de datos seleccionadas durante el periodo. de 2010 a 2020.
Resultados— Se encontraron un total de 20 artículos originales publicados, distribuidos así: revistas nacionales, 6 artículos; revistas internacionales, 7 artículos; y en bases de datos, 7 artículos.
Conclusiones— El uso de HMA en frutales es alentador en Colombia y en cierta medida también en el cultivo de mora, sin embargo, es necesario profundizar en aspectos relacionados con la capacidad de respuesta de cada cultivo a la simbiosis micorrízica, convirtiéndose esto en un obstáculo para la aplicación a mayor escala de esta biotecnología, así como incrementar la investigación científica sobre las especies nativas de HMA y su potencial micorrízico para lograr una agricultura más limpia y sostenible.

Published: July 2024

Introducción: Los dispositivos robóticos de rehabilitación de pacientes con impedimentos motrices se encuentran en amplio uso por cuanto impactan significativamente el proceso de rehabilitación al ofrecer un plan uniforme de ejercicios sin tener las variaciones típicas presentes entre diferentes terapeutas humanos. Estos dispositivos requieren de sensores de fuerza para monitorear la evolución en la recuperación del paciente. Dentro de los dispositivos robóticos para rehabilitación se encuentra el MIT-MANUS, el cual posee dos grados de libertad y se emplea en pacientes con problemas motrices en miembros superiores. Para poder complementar el uso de un sistema MIT-MANUS se requiere contar con un dispositivo que sea capaz de sensar fuerzas en el plano. Lastimosamente, los dispositivos comerciales son muy costosos y poco accesibles en países como Colombia. Se plantea por lo tanto el objetivo de investigación de desarrollar un sensor de fuerza para un sistema robótico MIT-MANUS que sea simple, robusto, económico y fiable.
Objetivo: Desarrollar un dispositivo de sensado en el plano que se capaz de detectar, con buena precisión y un error de medición aceptable, las fuerzas ejercidas por niñas y niños de hasta 10 años de edad.
Metodología: Se utilizó un enfoque de diseño metodológico de Ingeniería Mecánica, basado en las fases de concepción, diseño, validación CAE, construcción, ensamble y pruebas experimentales.
Resultados: El principal resultado de la investigación fue la construcción de un dispositivo de sensado validado experimentalmente capaz de medir  fuerza en el plano de hasta 60 N.
Conclusiones: Después de realizar las pruebas y ensayos experimentales, se pudo comprobar que el sensor es fiable al momento de medir una fuerza en el plano. El error máximo de medición de una fuerza en su componente horizontal o vertical es del 10%, el cual se reduce al 6% cuando el valor calculado corresponde a la resultante de la fuerza. La fuente de los errores es diversa, ya sea debido a la no homogeneidad del elemento metálico, el tipo de galga usada, los químicos empleados para soldar la galga al elemento mecánico, problemas de conversión ADC, entre otros, pero sus valores aceptables permiten emplear la galga en la aplicación a la que fue diseñada.
Use of biostimulants in fruiting crops’ sustainable management: A narrative review
Authors: Barreto Guilherme , Petry Claudia , Silveira Diógenes , Trentin Thomas , Turmina Ana Paula , Chiomento José Luís
Published: July 2024

Introduction: On a global scale, the obstacles to fruticulture correspond to the lack of skilled labor, the limited amount of available arable land, and the high costs of acquiring fertilizers and pesticides. These inconveniences, linked to environmental impacts and ecotoxicological damage, indicate that scientists, industries, and fruit growers have shown interest in the development of biotools for fruiting crops’ management aiming at orchards’ optimal production, such as biostimulants. This bioinput stimulates plant nutrition processes independently of the product’s nutrient content, aiming to improve efficiency in the use of nutrients, tolerance to abiotic stress, and the quality and availability characteristics of nutrients available in the growth medium. Objective: Thus, this narrative review aims to analyze the state-of-the-art regarding the use of biostimulants in fruticulture, compile information on the proper application of these bioinputs and present alternatives to the diffusion of biostimulants in fruit agroecosystems. The totality of bioestimulants’ action mechanisms still needs to be better understood. Results: The applicability of biostimulants in the management of fruiting crops proved to be a relevant possibility to grant sustainability to production systems in fruticulture and reduce costs, increasing productivity, shelf life, and reducing damage caused by climatic adversities in crops, mainly hydric stress. Conclusions: The development of specific legislation for biostimulants should contribute substantially to generating credibility with farmers in order to differentiate, for example, foliar fertilizers and microbial agents.
Evolving Dynamics of Higher Education Institutions and Their Cities (1980-2020)
Authors: Conteh Michael
Published: July 2024

This research examines the significance of higher education institutions (HEIs) as anchors in their host cities and their community engagement strategies from 1980 to 2020. By examining four case studies of urban-based universities that are members of the Coalition of Urban and Metropolitan Universities (CUMU) across diverse geographical and socio-economic contexts, this study analyzes the impact of anchor strategies on local communities, economic growth, and urban revitalization. Two public institutions—Rutgers University-Newark (RU-N) and the University of Pretoria (Mamelodi Campus, South Africa)—and two private institutions—Syracuse University (S.U.) and the University of Pennsylvania (UPenn)—comprise the four selected institutions.
Comparative analysis of the case studies reveals that effective anchor strategies frequently involve multidimensional approaches that address their respective cities' social, economic, and public safety challenges. In addition, I identify the key factors contributing to the efficacy of anchor strategies, such as strong leadership, stakeholder collaboration, and maximizing the role of foundations and long-term vision.
The findings of my study highlight the significance of universities as significant agents of urban change in guiding policymakers, urban planners, and higher education administrators who seek to harness the potential of universities in shaping sustainable and inclusive community
engagement. My findings highlight the interplay between universities and their environments rooted in their host cities.

Published: July 2024

The analysis of sound-absorbing structures is carried out taking into account their modern classification. The considered sound-absorbing structures can be used to reduce aircraft cabin and community noise levels. Depending on the spectrum of the main noise sources, the required type of sound-absorbing structure is selected, which is then adjusted to the problematic frequency range. Semiempirical and experimental methods are used to adjust sound-absorbing structures, and numerical methods are currently being actively developed.
