Published: February 2025

Se requiere desarrollar métodos sostenibles y eficientes para extraer compuestos bioactivos de la biomasa lignocelulósica (BL) para valorizar los subproductos agroalimentarios, forestales e industriales en el marco de la biorrefinería y de la economía circular. Esta contribución ofreció una visión general sobre la viabilidad y eficacia de la cal como agente de extracción, centrándose en la recuperación de arabinoxilanos (AX) de diversos materiales lignocelulósicos, para fomentar esta línea de investigación. La BL consiste en una estructura defensiva de las plantas, compuesta principalmente de celulosa, de hemicelulosa y de lignina, presentando recalcitrancia. Los hallazgos indicaron que el pretratamiento adecuado de la BL promueve la extracción eficiente de AX, siendo los métodos alcalinos particularmente efectivos para aumentar la solubilidad de los AX y facilitar su posterior aislamiento y purificación. El uso de la cal se presentó como una estrategia viable debido a su disponibilidad, bajo costo, selectividad, baja toxicidad y por facilitar la ruptura de enlaces éster entre xilanos (hemicelulosa) y lignina, lo que mejora la susceptibilidad de la celulosa y los xilanos a tratamientos posteriores. En conclusión, el uso de la cal se destacó como una estrategia efectiva para deconstruir la BL y obtener compuestos químicos de alto valor agregado, tales como los AX, con aplicaciones tecnológicas diversas, promoviendo la inclusión de la BL dentro de una economía circular

Authors: Rios Sangüeza Douglas G.
Published: February 2025

El presente trabajo aborda la problemática del uso inadecuado del esclerómetro en Bolivia, destacando la falta de procedimientos que relacionen ensayos no destructivos con la resistencia a compresión del hormigón. También se cuestiona la aplicabilidad de modelos extranjeros, que no consideran las características locales del material. Se desarrolló una metodología para generar modelos predictivos adaptados a las condiciones locales mediante esclerometría y SonReb. Se fabricaron probetas cilíndricas y prismáticas con cinco diseños de hormigón (resistencias entre 70 y 350 kg/cm²) y se realizaron ensayos de compresión, ultrasonido y esclerometría. Los modelos obtenidos, individuales y combinados, basados en regresiones de tipo potencial, fueron comparados con referencias internacionales. Los resultados muestran que la combinación de métodos como el número de rebote y la velocidad de pulso ultrasónico mejora la precisión de las estimaciones al mitigar errores por heterogeneidad. Los modelos SonReb lograron coeficientes de determinación r² ≥ 90% (máximo r² = 0.9722). Además, se diseñaron ábacos locales con factores de conversión de 0.95–1.05 para el esclerómetro y 0.97–1.03 para SonReb. Estas herramientas prácticas, rápidas y económicas optimizan la evaluación estructural en proyectos locales. En conclusión, se valida la importancia de adaptar métodos no destructivos a contextos locales, contribuyendo a evaluaciones más precisas y al desarrollo de infraestructura eficiente en Oruro.
Public Health Concern on Commercially Available Sachet Waters in Nigeria: A Mutagenicity, Genotoxicity and Health Risks Study
Authors: Adenrele Alabi Okunola
Published: February 2025

Sachet water is a common means of obtaining drinking water in many countries in Africa. However, there are concerns about the portability of this water type. This study investigated toxic metal concentrations in five commercially available sachet waters in Nigeria. The non-carcinogenic and carcinogenic risks were calculated. The Ames Salmonella fluctuation assay (Salmonella typhimurium: TA100 and TA98) and SOS chromotest (Escherichia coli PQ37) were used to assess the sachet waters’ capacity to cause DNA damage. A higher level of Cr, Cd, As, and Fe in the sachet waters than the allowable limit was recorded. There were substantial carcinogenic and non-carcinogenic hazards for both adults and children, according to data on the total carcinogenic (THQ) and non-carcinogenic (TCR) risks of some of the hazardous metals examined in the sachet waters. The values of these metals surpassed the tolerable threshold. The mutagenicity of the sachet waters was demonstrated by the Ames Salmonella fluctuation assay data. Comparing the mutagenic index of TA 98 and TA100, the earlier was more sensitive to all the water samples. The data obtained in the SOS Chromotest was similar to the data of the Ames test. The five sachet water samples in E. coli PQ37 induced a significant SOS response which indicates that the samples are genotoxic. When the two microbial assays were compared, the Ames Salmonella fluctuation appeared to be a little more sensitive in detecting genotoxins and mutagens in this study. These results are indication of the mutagenic, genotoxic and health effects that might occur in exposed individuals.

This study carefully described the achievement of rural youth employment opportunities: support to integrated agribusiness hubs project, tagged International Fund for Agricultural Development (IFAD) Agrihub project in Nigeria, and x-rayed its implication for sustainable development. It employed descriptive statistical design to analyse data obtained from the project beneficiaries, using carefully structured questionnaire developed by the project monitoring and evaluation team. Data were presented using frequency counts and percentages. Result shows that 50.1 percent of the beneficiaries were male, most of the beneficiaries (22.8%) were from Kaduna State while maize and soya beans production (14%), dairy production (11%) and renewable energy (10%) were the commodity value chains mostly engaged in by the project beneficiaries. Though the objectives of the IFAD Agrihub project were achieved, there is the need for consolidated efforts of all stakeholders to create enough employment opportunities for the growing youth population in Nigeria. Policymakers and development agencies who intend to design and implement projects with sustainable impacts for the citizenry should adopt the design of the IFAD Agrihub project. Doing this will guarantee the success of such project and create positive impacts that outlive the project on the beneficiaries.

Authors: M.A. BARA  , M.U. ABBA
Published: February 2025

The production of industrial wastewater containing heavy metals pollutants, including boron has caused a great deal of concern due to high concentration which is toxic and harmful to the environment. Several treatment technologies including, adsorption, electrocoagulation, chemical coagulation, chemical precipitation and membrane have been reported in eliminating boron from a generated effluent before discharge. The current study utilizes a hybrid system comprising of three compartments, namely adsorption, settling, and membrane compartment. Initially, at the adsorption section of the hybrid system, the wastewater was subjected to adsorption process for 250 minutes, using nano-magnetite sorbent. The remedied effluent was examined, and a considerable performance was noticed in the removal efficiencies of boron, turbidity, copper, and zinc with 74.39 %, at 250 minutes contact time. Though, the sorbent was able to achieve 74.39% boron removal rate alongside with 2.2 mg/L concentration. However, this concentration is still above the WHO/EU/DOE (0.5-1.0 mg/L) standard limit. Application of further treatment process became imperative to meet the standard discharge limit. A nanocomposite membrane was employed as treatment process to improve the efficiency of boron removal. The contaminants removal rate for neat (PVDF-PVP) and modified (1.0 wt% TiO2) membranes in respect to boron. The physicochemical analysis of the permeate revealed that the boron concentration was significantly reduced to 0.43 mg/L, which is far lower than the discharge limit of 1.0 mg/L. Finally, the modified hybrid TiO2 membrane has demonstrated to be effective in relegating boron from the wastewater.

Published: February 2025

The uncontrollable growth of the urban population in Abuja has brought a myriad of challenges. Increase in rural-urban migration, the economic, infrastructural, and social conditions in these urban centers have been incapable of providing a good standard of living for their inhabitants. With a population of about over 4 million, Abuja has faced different social amenities difficulties due to a lack of proper planning and management of dwellers. Using secondary data, the study expands on current knowledge with regard to the current challenges facing Abuja’s urbanization, the Federal Capital Territory. The study also analyses some of these long-standing challenges, their interrelatedness, and how they exacerbate the Nigerian government’s inability to solve them. Planning and mismanagement of dwellers which caused different gaps in the development of certain social amenities as well as led to the poor standard of living was discussed and carefully analyzed. Furthermore, the conclusion lays a response to these challenges with recommendations that Abuja City's transportation issues are worse than the national average and need to be addressed. Correcting the master plan's errors and flaws is necessary. Desertification in Abuja due to building and road construction activities should be checked by planting trees to protect the environment.
PARTY DOMINANCE AND POLITICAL HEGEMONY. A CASE STUDY OF YOBE STATE
Authors: ALI INUSA  , AISHA MOHAMMED KUCICI
Published: February 2025

his study examines the dynamics of party dominance and political hegemony in Yobe State, Nigeria, focusing on how the All Progressives Congress (APC) has maintained an overwhelming hold over the state's political landscape across multiple election cycles. Within Nigeria’s federal system, Yobe State serves as a case study of how dominant parties consolidate power to the detriment of opposition parties. The research adopts Gramsci’s theory of hegemony, which emphasizes the role of ideological leadership in shaping socio-political structures, to analyze the APC's entrenched authority in Yobe State. Utilizing a content analysis methodology, the study examines election results, party manifestos, political speeches, and media narratives to identify the key drivers of APC's dominance. Data were analyzed thematically to uncover patterns of electoral success, party loyalty, the influence of local political elites, and the alignment of the state's political culture with APC's interests. A notable finding reveals that APC’s dominance extends beyond electoral victories, as it has entrenched itself into the governance and social fabric of Yobe State, marginalizing opposition parties and stifling political competition. The study concludes that while APC's dominance provides political stability, it undermines democratic consolidation by limiting viable political alternatives and marginalizing opposition voices. To address this, the study recommends the creation of an enabling environment for opposition parties through the enforcement of fair electoral laws that ensure equal access to resources, media platforms, and political spaces. Additionally, opposition parties should focus on building grassroots networks to increase their visibility and voter engagement, which is essential for promoting political pluralism and strengthening democratic processes in Yobe State and beyond.

Introducción: La enfermedad de Goodpasture, también llamada
enfermedad antimembrana basal glomerular, es una enfermedad rara
autoinmune. Se caracteriza por la triada: hemorragia pulmonar,
glomerulonefritis proliferativa y anticuerpos anti-MBG. La manifestación
pulmonar está relacionada con efectos detonantes de tipo irritativo,
como el tabaquismo. Los síntomas más conocidos son la hemoptisis, tos,
disnea y fatiga. A nivel renal se manifiesta por afectación renal,
disuria, hematuria, proteinuria, edema de miembros pélvicos y torácicos,
e hipertensión y dolor de la fosa renal. El diagnóstico se basa en la
presencia de anticuerpos anti-MBG en plasma y/o tejido renal. Para el
diagnóstico del síndrome de Goodpasture verdadero se necesita que estén
presentes las enfermedades renales y pulmonares (la triada al completo).

Objetivo: Identificar la etiología, clínica y método de diagnóstico
de este síndrome, así como determinar cuál es el tratamiento apropiado.

Metodología: Se revisaron los artículos que contenían las
palabras clave seleccionadas al comienzo del estudio. De todos ellos,
se incluyeron los que cumplían con los requisitos de inclusión

Published: February 2025

El uso regular del dispositivo de vacío (VED) antes de la implantación
de una prótesis peneana (IPP) juega un rol crucial en la prevención de
la involución peniana. Esta práctica puede incrementar tanto la
distensibilidad del tejido peneano como el tamaño del pene en estado
de reposo, posibilitando la implantación de una prótesis de mayor tamaño.
Este aumento en tamaño facilita significativamente el proceso quirúrgico.

Además, es vital que el paciente reciba una formación adecuada sobre
cómo utilizar el VED y que haya un seguimiento constante por parte del
equipo de enfermería. Esto asegura una mejor adherencia al tratamiento
y minimiza los riesgos de uso incorrecto del dispositivo, lo que a su
vez puede reducir las complicaciones, acortar el tiempo de recuperación
y mejorar la satisfacción general del paciente.

Published: February 2025

Data has become paramount in the 21st century, from major contributors including social media, smartphones, individual health records, etc. Megabytes and gigabytes used to be the standard units of data storage, but nowadays Petta bytes and Zetta bytes of data are being produced at an exceptional rate and in a wide range of formats. Wireless sensor networks (WSN) are a type of WSN in which each node is equipped with sensing, processing, and communication capabilities. This network's ability to monitor and sense has led to its widespread use in fields as diverse as surveillance, military, medicine, and even the household. Networks that evolved from WSN to address problems peculiar to multimedia transmission are known as Wireless Multimedia Sensing Networks (WMSN). Video, audio, and visual content, as well as numerical data, can all be retrieved by the multimedia nodes. Every node in a WMSN has an energy limit. The network's lifespan is shortened because it's difficult to recharge or replace a dead battery. Transmission of video, music, images, and scalar data by wireless multimedia sensor nodes will increase their power consumption. In addition, the efficient operation of the network is contingent upon the following parameters being met during the transfer of multimedia data: a large bandwidth, high transmission of packets ratio, excellent throughput, acceptable end to end a delay, tolerable jitter, less frames loss rate, and low computation time. The sum of these measurements is the network's Quality of Service (QoS). A network's lifetime is defined as the amount of time it is able to function normally and carry out its designated function. To extend the useful life of multimedia networks, we devised a novel splitting of the underlying multidimensional functional structure and integrated it with Machine Learning techniques.

Published: February 2025

The exponential growth of data derived from the Internet exceeds the social networks plateforms such as Facebook, Twitter and so on. This data includes a wide range of sensor data from a variety of sources, such as IoT devices, satellite data and so on. This massive amount of data led to the emergence of ”Big Data” concept. This new trend has had a considerable impact, particularly in the ffeld of decision support systems. In particular, these impacts are mainly observed in the extraction, transformation and loading processes within business intelligence systems. In this context, three main challenges emerge: dealing with large quantities of data, various types of data and rapid data generation. In this paper, we present and discuss the state of the art of research focused on ETL processes while addressing the challenges of big data. Our study aims to determine the degree to which these works take into account the characteristics of big data in their approaches. Finally, we provide an overview of a new approach to ETL processes, called BRS-ETL, which supports heterogeneous and streaming data.
Of Efficient Fragments: Reification and British Aestheticism
Authors: Kanarakis Yannis
Published: February 2025

This paper utilizes Fredric Jameson’s work on the concept of “reification” as a means of considering the artistic movement of aestheticism as the cultural logic of late nineteenth century capitalism. The paper intends to show that Jameson’s concept can help us approach this paradoxical relation in a systematic way, where, on the one hand, the aesthetes propounded artistic autonomy, while, on the other, they were actively engaged with market policies. The objective of this paper is to demonstrate that fragmentation in aestheticist works through the concept of reification which functions as a means of intensifying emotional response and of increasing the efficiency, and thus the impact of the work, in a manner that is reminiscent of advertising or even market practices, rendering the movement a cultural counterpart of late nineteenth century capitalism.
“…town that doesn’t keep showing up in books”: Genre Reflexivity in Post-Millennial Metafictional Horror
Authors: Thompson Dominic
Published: February 2025

Metafiction and horror can be traced back as far as classical antiquity and even the early ages of oral storytelling, but it is their relationship within a post-millennial readership with which this paper is concerned. Metafictional horror—as it appears towards the end of the twentieth century and, more specifically, the beginning of the twenty-first century—is written against a backdrop of unavoidable, mass-mediated horrors within the realm of the real. In the face of worldwide threats—which included, but were not limited to, pandemics, terrorism, extreme weather events, and economic crises—this essay asks what metafictional horror looks like in the shadow of such events which preceded and superseded the millennium, and what this post-millennial metafictional horror is trying to say about the horror genre itself. Deconstructing the terms horror, metafiction, and metahorror along etymological, historical, and cultural lines, this paper uses David Wong’s John Dies at the End as a case study, which stylistically deploys genre reflexivity. Wong’s text will form the basis of a horror genre analysis to show that his metahorror allows for the text to provide a nuanced discourse on horror fiction’s traditional consumption across multiple mediums, notably in literature, film, and video-gaming.
The Posthuman Lifeworld: A Study of Russell T. Davies's Doctor Who
Authors: Hay Jonathan
Published: February 2025

Via the analysis of a cross-section of episodes from Russell T. Davies’s era of the revived BBC Science Fiction television series Doctor Who (2005–2010), this paper demonstrates that the programme utilises representations of the viewer’s everyday lifeworld to figure a posthuman rhetoric. Through the viewer’s in-phenomenal interaction with its representation of the mundane, the show emphasises the already significantly posthuman nature of the technologically saturated lifeworld of the contemporary individual. It challenges Darko Suvin’s notion of cognitive estrangement, which fails to describe the show’s Science Fictional discourse, and instead proposes the alternate mechanism of cognitive engagement. This inquiry, therefore, reappraises the thematic concerns of the show during the years when Russell T. Davies served as the programme’s showrunner, revealing Doctor Who’s emphasis upon the everyday (post)human lifeworld. It concludes that the show refutes technocentric ideologies, and thus rigorously demonstrates the consonance between the (post)human present and posthuman future.

Vol. 76 (4) 2024 ARTICLES A Survey of the Kremenski Lakes (Pirin National Park) Suggests that the Vairone Telestes souffia Risso, 1826 (Actinopterygii: Cyprinidae) Is Not a Native Species of the Fauna of Bulgaria
Authors: Apostolou Apostolos , Kazakov Stefan
Published: February 2025

Vairone Telestes souffia is known from Bulgaria based on two specimens sampled from the Lower Kremensko Lake (Pirin National Park) in 1988. A survey of the fish fauna conducted in August 2021 in Lower and Middle Kremensko Lakes suggests that there are not a population of this species at these localities. The only record from 1988 is recognised as a possible consequence from an unregulated fish introduction. Therefore, this study suggests that Telestes souffia has to be excluded from the list of species needing conservational measures in Bulgaria.

Although both Finland and Norway are part of a common Nordic education culture, Finland have consistently outperformed the other Nordic countries in PISA studies. In this study, we compare Finnish and Norwegian textbook series. The results indicate that both textbook series largely facilitate skill efficiency, and most tasks are low cognitive demand. However, the Finnish textbook series facilitate conceptual understanding to a greater degree. The Finnish textbook series also introduce and develop connections between a greater number of mathematical ideas, and there is a greater number and proportion of high cognitive demand tasks in the Finnish textbooks.

Кроз овај рад настојали смо да покажемо како су пописи становништва у XX и XXI вијеку, извршени од стране три различита државна организма, детектовали српски национални осјећај код станов- ништва у Боки Которској и да ли је она по томе ишта другачија од остатка Црне Горе. Настојали смо да увидимо да ли је у Боки Которској било више или мање Срба, како се њихов број мијењао од пописа до пописа и, ко- начно, како су према резултатима пописа Срби распоређени на простору тог дијела црногорске обале. Рад је примарно заснован на објављеним документима, тј. резултатима пописа становништва из 1910, 1921, 1931, 1948, 1953, 1961, 1971, 1981, 1991, 2003. и 2011. године, а затим и на стручној литератури.

Када је писао предговор за Дедијерову књигу Велики бунтовник Милован Ђилас: прилози за биографију, Кристофер Фарли се питао ко све заслужује да о њему буде написана биографија: „они који имају моћ, они који унапређују људско знање или разумевање, који су дали велика дела на пољу уметности, проналазаштва и напретка или, можда, на другој страни, они који су стекли славу по добру или злу, и они чији животи илу- струју важне истине о временима у којима су живели.“1 Дакле, биографију заслужују све оне личности које су на одређен начин стварале историју. Међутим, не смемо заборавити ни оне који су о историји писали.

Authors:   Universitas Indonesia, Indonesia, Nurohmah Salsabila
Published: February 2025

The purpose of this study is to determine the effectiveness of events as a digital content marketing strategy. Digital content marketing has two main indicators: valuable content and content sharing. Meanwhile, in the event business, it has indicators of cognitive, psychological experiences, leisure experiences, event satisfaction, and event quality. The method in this study is interviews and direct observation through an internship program at IFCA PT PFN. The results of this study show that the effectiveness of events in the form of training and workshops as a digital marketing strategy has a significant impact on the products owned by IFCA. The content marketing presented by IFCA currently through the IFCA website and social media presents informational content. However, this is still not optimal because the public awareness is still low due to the lack of human resources to manage digital marketing activities.

This study investigates the impact of online gaming on the physical health of vocational program students at the University of Indonesia, amidst the growing popularity of this activity in the digital age. Utilizing a survey method, data were collected through questionnaires to assess gaming habits and their associated health effects. Findings reveal that while students report feelings of happiness and satisfaction from gaming, they also acknowledge adverse health outcomes. Notable issues include fatigue from prolonged gaming sessions, poor dietary habits, and sleep disturbances. Although a significant majority (94%) feel in control of their gaming time, a considerable portion (84%) recognizes the necessity to limit play to safeguard their health. The study underscores the critical need for education and awareness regarding the health risks linked to online gaming addiction among university students. It advocates for preventive measures to mitigate potential health issues and calls for further research involving health professionals to develop effective intervention strategies.

The title of the proposed research is "Information Literacy Skills of Early Childhood Education (ECE) Teachers in Efforts to Enhance Pedagogical Competence of ECE Teachers in Central Lampung Regency." This research aims to explore the information literacy skills of ECE teachers in the Central Lampung Regency, Lampung Province, using the ACRL (Association of College & Research Libraries) standards, and to understand how ECE teachers can meet the demands to improve their professional competence in line with current technological and informational developments. The research adopts a qualitative case study approach with a mixed methods methodology (interviews, observations, and surveys). The research findings indicate that ECE teachers in the Central Lampung Regency are able to identify information needs by formulating problems beforehand. However, the information search process often employs very basic strategies, limited to typing keywords. Moreover, in the process of evaluating information sources, ECE teachers, whether in ECE or higher levels, tend to only use additional information to verify the accuracy of the information obtained. In using and communicating information, teachers generally combine new information with existing knowledge to create summaries. Furthermore, through this research, the extent of ECE teachers' understanding of academic ethics, such as avoiding plagiarism by citing the sources of information used, will also be examined. ECE teachers who apply information literacy in the learning process by presenting problems to early learners are expected to foster better foundational understanding and develop critical thinking skills for ECE students in the future.

The development of a THz system often requires a device that is used to radiate or detect THz waves. One way to fulfill this requirement is to use an antenna. Therefore, we need to consider the radiation characteristics of an antenna working in the THz region. In this paper, we present simulation study of two dipole antennas, i.e. a planar strip dipole antenna and a slot dipole antenna. The simulation results show that a planar strip dipole antenna has a better radiation efficiency (more than 95%) compared to the slot dipole. It also shows that an efficiency of more than 98% can be achieved when using silicon dielectric substrate. Furthermore, a return loss characteristic of 38,752 dB can be achieved by using a silicon dielectric substrate and a metal layer of Au for the planar slot dipole antenna.
