Las bacterias nativas adaptadas a ambientes contaminadas han demostrado su gran capacidad de sobrevivir en condiciones adversas. El objetivo de este estudio fue identificar las bacterias presentes en suelos de minas abandonadas, además de investigar las relaciones filogenéticas de estas bacterias nativas cultivables. Se realizó el aislamiento bacteriano, la extracción de ADN, amplificación por PCR, secuenciación del gen 16S ARNr, reconstrucción filogenética de Máxima Verosimilitud (ML) con RaXML, e identificación de géneros relacionadas con microreact. Las secuencias obtenidas fueron editadas a un tamaño de 1200 – 1400 pb, que posteriormente se compararon con 1137 secuencias procedentes de la base de datos del GenBank. Los nueve aislamientos obtenidos se agruparon filogenéticamente en seis grupos que corresponderían a los géneros Bacillus, Cytobacillus, Paenibacillus, Microbacterium, Peribacillus, Acinetobacter. Por lo tanto, se resalta el potencial inexplorado de estas bacterias para ser utilizadas en procesos de biorremediación. Además, algunas de estas bacterias pueden ser propuestos como indicadores de contaminación, lo que amerita realizar una investigación más detallada debido a que estos microorganismos pueden ser empleados en futuras investigaciones.

Authors: Jiehui Zheng , Su Yingying , Wang Wenhao , Li Zhigang , Wu Qinghua
Published: March 2024

With the maturity of hydrogen storage technologies, hydrogen-electricity coupling energy storage in green electricity and green hydrogen modes is an ideal energy system. The construction of hydrogen-electricity coupling energy storage systems (HECESSs) is one of the important technological pathways for energy supply and deep decarbonization. In a HECESS, hydrogen storage can maintain the energy balance between supply and demand and increase the utilization efficiency of energy. However, its scenario models in power system establishment and the corresponding solution methods still need to be studied in depth. For accelerating the construction of HECESSs, firstly, this paper describes the current applications of hydrogen storage technologies from three aspects: hydrogen production, hydrogen power generation, and hydrogen storage. Secondly, based on the complementary synergistic mechanism of hydrogen energy and electric energy, the structure of the HECESS and its operation mode are described. To study the engineering applications of HECESSs more deeply, the recent progress of HECESS application at the source, grid, and load sides is reviewed. For the application of the models of hydrogen storage at the source/grid/load side, the selection of the solution method will affect the optimal solution of the model and solution efficiency. As solving complex multi-energy coupling models using traditional optimization methods is difficult, the paper therefore explored the advantages of deep reinforcement learning (DRL) algorithms and their applications in HECESSs. Finally, the technical application in the construction of new power systems supported by HECESSs is prospected. The study aims to provide a reference for the research on hydrogen storage in power systems.
„Na gwiazdkę nie będzie mnie jeszcze.” Żołnierze polskiego państwa podziemnego okręgu Armii Krajowej Pomorze przetrzymywani w męskim rozszerzonym więzieniu policyjnym na Radogoszczu w Łodzi w latach 1940–1945

Przedmiotem artykułu jest ukazanie egzystencji żołnierzy Polskiego Państwa Podziemnego Okręgu Armii Krajowej Pomorze w męskim Rozszerzonym Więzieniu Policyjnym na Radogoszczu w Łodzi w czasie II wojny światowej. Żołnierze, zakwalifikowani jako więźniowie polityczni, byli szczególnie narażeni na brutalność ze strony załogi więzienia oraz Tajnej Policji Państwowej, która prowadziła względem nich śledztwo. W artykule zwrócona została uwaga zarówno na relacje między więźniami, jak również na więzi łączące osadzonych z ich rodzinami, zwłaszcza w kontekście prowadzonej przez nich tajnej korespondencji. W styczniu 1945 r. ci z żołnierzy, którzy nie zostali wywiezieni transportami specjalnymi do obozów koncentracyjnych, ponieśli śmierć w czasie likwidacji więzienia. Rodziny na wieść o podpaleniu więzienia wyruszyły do Łodzi, by w zgliszczach zidentyfikować ciała swoich bliskich.
The Arabic Poetry Of Al-Tafi’ila: Between The Terminology And the Rhythmic Determinants
Authors: Alomari Salameh Mohammad Rida
Published: March 2024

This study aims at clarifying the rhythmeic values of the ancient and modern meters of Arabic poetry as a basic tool in the Arabic language teaching/learning process. It seeks to enable the students to compare and contrast the Arabic rhythm in terms of 'Tafi’ila'. It is based on pursuing the facts of the connection and the separation between the deliberative prosodic studies’ description of the nature of the rhythm that governs what is called the term 'Al-Tafi’ila poetry'. In addition, the path of the actual verification of this rhythm in modern Arabic poetry, which is done through the systematic investment in Al-Khalil’s theory to examine the rhythmic basis of "Al-Tafi’ila poetry". It is found that this examination of the theory of traditional prosody allows to remove the ambiguity about the claims of the radical modernization brought about by the “Al-Tafi’ila” system on the contemporary Arabic poem. It will also establish a comprehensive conception of the reliability of the term "Al-Tafi’ila poetry" in representing the rhythmic nature of the poems that belong to it.
‘It’s a Family Matter’: Inaction and Denial of Domestic Violence
Authors: Sultan Maheen , Mahpara Pragyna
Published: March 2024

This article provides a grounded example of backlash in action surrounding the implementation of the Domestic Violence (Prevention and Protection) Act 2010 in Bangladesh. While formulation and enactment of the law marked significant achievements, its implementation has been weak. Unlike conventional analyses that concentrate on backlash in gender equality policy formulation, this study focuses on the obstacles encountered during the implementation phase. Through in‑depth interviews with advocates and stakeholders responsible for implementation, the article examines their attitudes and interests concerning the law and women’s rights to life, dignity, and bodily integrity. Prevailing gender norms perpetuate the trivialisation of domestic violence, framing it as a personal issue of minimal importance. Consequently, service providers tend to delegitimise and deprioritise it. This article investigates the strategies and tactics of deliberate inaction employed by backlash proponents, which is different from lack of capacity, and explores the counter‑strategies deployed by advocates aiming to ensure the Act’s effective implementation.

Authors: Ahmed Adeepto Intisar , Jahan Ishrat , Hasan Israr , Rashid Sabina Faiz , Naomi Sharin Shajahan
Published: March 2024

Public university campuses in Bangladesh have been historically significant sites of negotiating with social and political orders. Based on in-depth interviews with male and female students from three public universities in Dhaka, conducted between 2022 and 2023, this article identifies the ways in which formal and informal structures of power on campus reproduce patriarchal norms and gendered inequities. The students’ narratives shed light on how the culture of residential halls, and practices of policing and surveillance, interact with patriarchal norms to limit women’s agency and mobility. They also show the ways in which masculine practices which draw from hypersexual views on women and glorify violence become enabled and sustained by institutional power dynamics, wherein harassment and policing become instruments to negotiate power. The article provides new insights into the ways in which patriarchal power dynamics and gender norms promoted and practised within an institutional space create drivers of anti‑feminist backlash.

Bursera microphylla A. Gray (Burseraceae) es una planta medicinal mexicana con un destacado potencial antiproliferativo y antiinflamatorio in vitro que ha sido asociado a la presencia de compuestos del tipo lignano y triterpenoide, sin embargo, las propiedades farmacocinéticas (absorción, distribución, metabolismo, y excreción - ADME) y los posibles blancos farmacológicos de estos compuestos son desconocidos. El objetivo del estudiofue establecer in-silico el perfil ADME de los metabolitos bioactivos de B. microphylla y analizar los principales objetivos moleculares que son potencialmente inhibidos por estos compuestos. El análisis ADME de los compuestos de B. microphylla (14 lignanos y 10 terpenos) se realizó utilizando la herramienta SwissADME. La determinación in-silico de losposibles blancos terapéuticos se realizó utilizando el programa SwissTargetPrediction. En general, los lignanos y terpenos de B. microphylla presentaron un perfil ADME favorable. El análisis predictivo arrojó que hinoquinina inhibe a los transportadores de dopamina (DAT) y norepinefrina (NET). Por su parte, β-cariofileno reconoce al receptor cannabinoide tipo 2 (CB2). Compuestos con actividad antiproliferativa como ariensina, burserano, dihidroclusina, picropoligamina y burseranina mostraron alta biodisponibilidad oral. Todos los compuestos analizados mostraron capacidad de inhibir enzimas del metabolismo hepático, como CYP1A2 y CYP2C19. Las propiedades farmacocinéticas y farmacodinámicas aceptables de los lignanos y terpenos de B. microphylla los posicionan como buenos prospectos para ser evaluados en modelos animales de inflamación, analgesia, cáncer y enfermedades psiquiátricas. La potencial inhibición de las CYP’s es un aspecto que debe ser considerado para evitar reacciones adversas en una terapia combinada.

Published: March 2024

El objetivo de esta investigación fue analizar las tendencias de precipitación, temperatura máxima y mínima en el Distrito de Desarrollo Rural Atlacomulco (DDRA) para una serie de tiempo del ciclo agrícola primavera-verano para el cultivo maíz (abril-noviembre). El estudio examina la  tendencia para el período 1985-2017 de 30 estaciones meteorológicas. Se ha empleado una técnica no paramétrica de Mann-Kendall (MK) para establecer la tendencia estadística en la serie, así como la prueba paramétrica de Regresión Lineal, para conocer la magnitud de esa tendencia. Se encontró que la precipitación, la temperatura máxima y temperatura mínima presentan una tendencia positiva no significativa durante el periodo de estudio, presentando un incremento del 8.5, 4.7 y 12.9%, respectivamente. No obstante, al fraccionar la información en tres series de tiempo, se pudo identificar una tendencia significativa decreciente para la precipitación en el periodo 2007-2017 y en temperatura máxima hacia el periodo 1996-2006. Al analizar individualmente las estaciones meteorológicas, se encontró una heterogeneidad de tendencias, guardando relación entre ellas de acuerdo a su cercanía y condiciones geográficas. A partir del análisis, los resultados confirman que existen cambios en los patrones climáticos en el DDRA que podría impactar la producción de maíz, por lo que es necesaria la participación conjunta de  agricultores y gobierno en prácticas de adaptación al cambio climático, implementando políticas ante este fenómeno emergente y ya presente.

Published: March 2024

Las especies de plantas exóticas invasoras causan graves impactos en la estructura y funcionamiento de los ecosistemas invadidos, dejando en desventaja a las especies nativas. Eucalyptus globulus y Pinus halepensis, son dos especies caracterizadas por su amplia distribución y alta habilidad competitiva. El objetivo de este estudio fue comparar el efecto alelopático del lixiviado de la hojarasca de E. globulus y P. halepensis sobre la germinación, crecimiento y diversidad de especies de plantas silvestres altoandinas. Se colectaron 30 muestras de suelo de los primeros 10 cm a partir de cuadrantes de 1 m2. Los lixiviados afectaron negativamente la germinación, crecimiento y diversidad de especies de plantas silvestres, particularmente el lixiviado de eucalipto. Al ser este uno de los pocos estudios hechos en zonas altoandinas, es necesario la realización de estudios en condiciones naturales y en mayores escalas temporales, para evaluar con mayor precisión los efectos sobre la biodiversidad.

Published: March 2024

La frambuesa es una frutilla de gran demanda en el mercado internacional. Su principal atractivo radica en el alto contenido en vitaminas A y C, fibra, nutrientes como Ca y Fe, flavonoides y antioxidantes. Estos compuestos, además de ser integrantes en su aroma y sabor, contribuyen a fortalecer el sistema inmunológico del ser humano contra enfermedades como el cáncer, diabetes y cardiovasculares. Las hormonas endógenas influyen en el rol de esas moléculas durante el crecimiento en varias especies hortícolas. En frambuesa es desconocido la presencia de hormonas naturales en el fruto. Por ello, se investigó su presencia en frutos de frambuesa cv UANC-2022, utilizando la técnica de cromatografía de gases y espectrometría de masas con un diseño completamente al azar. Se identificaron las giberelinas A4, A7, A44 y A53; auxina ácido indol acético y la citocinina zeatina.

Published: March 2024

La hidroponía es la tecnología de la agricultura sin suelo, en la que las plantas crecen en un medio acuático. Mientras que la acuaponía es un sistema de producción de alimentos en rápido crecimiento que integra la hidroponía con la acuicultura (cultivo de peces). El objetivo de este estudio fue comparar la producción de acelga (Beta vulgaris var. Cicla L.) mediante un sistema hidropónico típico y un sistema acuapónico de producción de tilapia (Oreochromis niloticus) en invernadero. Se utilizaron seis sistemas de recirculación independientes para comprobar la producción por triplicado. Un análisis de regresión lineal simple indicó que la tasa de producción de hojas difirió de forma significativa entre sistemas (p < 0.05), ya que en el hidropónico se obtuvieron 3.46 hojas semana-1, mientras que en el acuapónico fue de 1.53 hojas semana-1. La biomasa vegetal aumentó 53.91 g semana-1 en el tratamiento hidropónico y 38.24 g semana-1 en el acuapónico, aunque dichas tasas de producción no difirieron significativamente (p>0.05). No se detectaron diferencias significativas en las concentraciones de amonio (NH4+), nitrito (NO2-), y fosfato (PO4+) en ambos tratamientos; pero se encontraron diferencias significativas para nitratos (NO3-) entre sistemas (p < 0.05). La producción de acelgas en el sistema hidropónico fue mayor que en el sistema acuapónico en cuanto al número de hojas y la biomasa.

The task of verifying credible and original information is now more complicated, especially for undergraduate students. This study uses information literacy and discourse analysis to develop English as a foreign language learners’ critical reading skills while verifying information on social media. A reading test including false news was used to assess the learners’ awareness of the credibility of social media information. Then, they were divided into experimental and control groups. The experimental group was trained in evaluating a set of false news using information literacy and discourse analysis skills. The control group did not receive any training. The experiment was conducted again on both groups. The results show a significant improvement among the experimental group compared to the control group. The findings of this study shed light on the growing need for creating a pedagogical space in English as a foreign language classroom that focuses on raising learners’ awareness of information literacy and discourse analysis skills to read with critical perspectives.

Published: March 2024

Reproductive emergencies are common in female cats, so, with the aim of contributing to the knowledge of the most frequent reproductive emergencies in this specie, a prospective study of patients treated at a University Veterinary Hospital was performed. All medical records of feline females, who were admitted like emergency related to the reproductive system, were analyzed. All data from epidemiological and clinical interest were registered. During 64 days, 20 female queen cats were monitored, and 13 had dystocia (65%; 13/20) and seven (35%; 7/20) pyometra. Many reproductive emergencies in the animals studied were related to contraceptive use. These findings should serve as a basis to veterinary clinicians to discourage this practice and encourage the neutering of females, thus providing quality care to clients and patients.

Published: March 2024

O estudo analisou a possível associação do estado nutricional pós-covid-19 com a persistência de fraqueza muscular generalizada. Participaram 28 adultos, de ambos os sexos, entre 20 e 59 anos. Investigou-se o estado nutricional atual, a distribuição do tecido muscular, a força de preensão palmar e as possíveis complicações apresentadas durante a infecção ativa. Os participantes foram divididos em três grupos: internação por ≤30 dias (n=7), internação >30 dias (n=7) e apenas isolamento domiciliar (n=14). Houve predominância de infecções moderadas, sem necessidade de internação, pneumonia em 64,3%, intubação em 35,7% e traqueostomia em 17,6%. A maioria dos participantes apresentava excesso de peso pré-covid-19, eutrofia após a cura da doença, mas regresso ao sobrepeso/obesidade no momento da coleta do estudo. Mesmo sem uma depleção muscular considerável, a fraqueza global persistiu em 78,6% da amostragem, sugerindo que a hiperinflamação iniciada na covid-19 perpetua no pós-covid, influenciando sequelas, como a fraqueza muscular independentemente de desnutrição proteica.

Authors: Yustina Andi Ina , Aritonang Elisha Princess Christin Natalia , Andrianantenaina Hajanirina
Published: March 2024

This study aims to investigate whether time budget pressure, sleep quality, and ego depletion affect the quality of audit judgment. A quantitative approach was used to collect data from 100 auditors working in both Big Four and Non-Big Four accounting firms. We tested the hypothesis using the Sequential Equation Model-Partial Least Squares (SEM-PLS) technique. The results of this study showed that time budget pressure and sleep quality do not have a significant impact on audit judgment. However, ego depletion has a negative impact on audit judgment. These findings can be beneficial in two ways. Firstly, the study provides an early warning to the human resources department or partner of a public accounting firm about the current phenomenon among auditors. Secondly, other researchers who are interested in exploring factors influencing audit judgment during the high season or peak season can benefit from this study.

Negative Temperature Coefficient Properties of Natural Clinoptilolite
Authors: Schiavo Loredana , Aversa Lucrezia , Verucchi Roberto , Castaldo Rachele , Gentile Gennaro , Carotenuto Gianfranco
Published: March 2024

Electronic negative temperature coefficient (NTC) materials are usually based on ceramic semiconductors. A new type of NTC-material is represented by zeolites. Indeed, zeolites are single-charge carrier ionic conductors with a temperature-dependent electrical conductivity. In particular, electrical transport in zeolite is due to the monovalent charge-balancing cations, like K+, capable of hopping between negatively charged sites in the silico-aluminate framework. Owing to the highly non-linear electrical behavior of the traditional electronic NTC-materials, the possibility to have alternative types of materials, showing linearity in the electrical behavior, is very desirable. Among different zeolites, the natural clinoptilolite has been selected for investigating the NTC behavior since it is characterized by high zeolite content, convenient Si/Al atomic ratio, good mechanical strength, due to its compact microstructure, and low toxicity. Clinoptilolite has shown a rapid and fully reversible impedance change with heating, characterized by a linear dependence on temperature. The X-ray photoelectron spectroscopy (XPS) analysis has been used for the chemical characterization of the natural clinoptilolite sample as it provides important information on the cationic content and framework composition. In addition, since electrical transport takes place in the free-volume of zeolite, the Brunauer–Emmett–Teller (BET) analysis has been also provided.
