Effective communication is crucial in the hospitality industry, yet there remain gaps in understanding how digital tools influence service quality and guest satisfaction. This study investigates the impact of WhatsApp Business on communication practices and service delivery at Four Points by Sheraton Batam. With the rapid evolution of technology, the hospitality sector must adapt to meet contemporary guest expectations. Utilizing a qualitative research approach, data were gathered through in-depth interviews and observations of staff and guest interactions over a three-month period. Findings reveal that WhatsApp Business significantly enhances responsiveness, streamlining communication between staff and guests. Staff reported that the application facilitated quicker resolutions of guest requests and complaints, ultimately contributing to a more positive overall experience. Moreover, the study found that effective use of WhatsApp Business improved accessibility, making it easier for guests to voice their needs. While these results are promising, the research also highlights that factors such as staff training, management commitment to customer service, and existing operational protocols play critical roles in determining overall service quality. This study underscores the relevance of integrating digital communication tools within the hospitality sector and provides insights applicable to other service-oriented fields, including school counseling. In conclusion, the adoption of digital tools like WhatsApp Business can substantially elevate guest experiences, aligning with contemporary expectations in the digital age. However, limitations such as a small sample size and the focus on a single hotel indicate the need for further research to explore the long-term effects of digital communication tools in enhancing service quality within the hospitality industry.

The Beijing Sentence Corpus II: A cross-script comparison between traditional and simplified Chinese sentence reading
Authors: Yan Ming , Pan Jinger , Kliegl Reinhold
Published: January 2025

We introduce a sentence corpus with eye-movement data in traditional Chinese (TC), based on the original Beijing Sentence Corpus (BSC) in simplified Chinese (SC). The most noticeable difference between TC and SC character sets is their visual complexity. There are reaction time corpora in isolated TC character/word lexical decision and naming tasks. However, up to now natural TC sentence reading corpus with recorded eye movements has not been available for general public. We report effects of word frequency, visual complexity, and predictability on eye movements on fixation location and duration based on 60 native TC readers. In addition, because the current BSC-II sentences are nearly identical to the original BSC sentences, we report similarities and differences of the linguistic influences on eye movements for the two varieties of written Chinese. The results shed light on how visual complexity affects eye movements. Together, the two sentence corpora comprise a useful tool to establish cross-script similarities and differences in TC and SC.

The electronic and optical properties of a composite created by introducing a magnetite cluster into NaA zeolite have been investigated in this work using DFT calculations. The results obtained indicate that the electronic and optical properties of the composite are enhanced because of the cluster. However, the properties exhibited by the cluster outside the zeolite differ from those it presents when it is part of the composite. It is noteworthy that the composite exhibits magnetic properties of a half-semiconductor and a strong optical response within the visible and ultraviolet regions of the spectrum.

Introduction. The formation of the stock market of Ukraine was initiated by the introduction of key laws. At the same time, the first Ukrainian shares and the first securities traders appeared, the formation of information and statistical data began, which makes it possible. To analyze the current state of the stock market, to study its trends and areas of support for the sustainable development of economic sectors.
The purpose of the paper is to study the peculiarities of the functioning of the domestic stock market in modern conditions.
Results. The formation of the stock market of Ukraine was initiated by the introduction of key laws. At the same time, the first Ukrainian shares and the first securities traders appeared, the formation of informational and statistical data began, thanks to which it is possible to study the main trends of the functioning of the stock market. According to Market Classification MSCI research, the Ukrainian stock market belongs to the group of countries with a low level of stock market development. The Ukrainian stock market is mainly represented by the debt segment. With the beginning of the full-scale russian invasion of Ukraine, operations on the stock market were suspended. Financial contracts were concluded individually for five months, which prevented actions that could destroy the market. In that period, the main instrument on the stock market was bonds of the domestic state loan of Ukraine. The resumption of the functioning of the stock market was marked by a slow increase in the volume of financial contracts. During the ten months of 2024, the state of the stock market continues to be characterized mainly by transactions with debt securities, we observe a slight increase in the number of contracts on the stock market. Statistics on stock market instruments do not contain information on such a financial instrument as a promissory note, but its use is appropriate in securing and supporting the agricultural sector.
Conclusion. Тhe stock market is mainly characterized by the debt segment in the form of OVDP; ten months of 2024 are characterized by positive dynamics of the volume of exchange contracts with securities; certain steps are being taken on the stock market to support the state and sectors of the economy; a negative feature of the domestic stock market is the lack of infrastructure for attracting foreign investors; Ukrainian companies choose foreign markets with higher liquidity and availability of capital.

Published: January 2025

This study examines the impact of transformational leadership on employee performance in small and medium-sized enterprises (SMEs) in Abuja, Nigeria. It focuses on the dimensions of Inspirational Motivation (IM), Individualized Consideration (IC), and Intellectual Stimulation (IS). The study population included approximately 15,000 SMEs in Abuja, with a sample size of 450 determined using Yamane’s formula, which accounts for a 20% non-response rate. Using a survey research design, data were collected through structured questionnaires and analyzed using multiple regression analysis to assess the relationships between leadership dimensions and employee performance outcomes. The findings reveal that IM (B = .645, p < .001) and IC (B = .314, p < .001) significantly enhance employee performance, fostering engagement, retention, and productivity, while IS (B = .011, p = .469) had a minimal impact due to resource and institutional constraints. The study recommends prioritizing IM and IC to address immediate performance challenges and employee retention while progressively incorporating IS as a long-term strategy to promote innovation.

Народнохозяйственное значение ячменя определяется его универсальным применением. Ячмень поражается многими болезнями пятнистости листьев. Среди грибных болезней на урожайность и качество ячменя оказывают возбудители сетчатой пятнистости (Pyrenophora teres) и мучнистой росы (Blumeria graminis f.sp. hordei). Устойчивость ячменя к болезням является полигенной, то есть оценивается по неспецифической горизонтальной и олигогенной специфической вертикальной устойчивости к определённым расам. Одной из важных задач селекции является создание устойчивых сортов к болезням.
В период 2020-2023 гг в условиях искусственного инфекционного фона «Казахского научно-исследовательского института земледелия и растениеводства» были изучены коммерческие и коллекционные 216 сортов-образцов озимого и ярового ячменя из конкурсного сортоиспытательного питомника, проведена оценка их хозяйственно-ценных признаков в полевых и лабораторных условиях. В ходе исследования проведено сравнительное изучение элементов структуры урожайности сортообразцов ячменя, устойчивых к болезням (масса 1000 зерен, продуктивность колоса, озерненность колоса, масса зерна с одного колоса и урожайность).
Целью статьи является анализ хозяйственно-ценных признаков сортообразцов ячменя, устойчивых к грибным болезням.

Ячмень – ценная зерновая, продовольственная и техническая культура, его зерно широко используется в пищевых и кормовых целях.
Повышение урожайности и качества зерновых культур, в том числе ярового ячменя, является основой экономической устойчивости сельскохозяйственных предприятий. Устойчивый рост производства зерна сегодня связан с интенсификацией технологического процесса возделывания, направленного на создание высокопродуктивных посевов, повышение качества зерна при сохранении экологической безопасности, снижение ресурсо- и энергозатрат. Ячмень требователен к почвенному плодородию. Это обусловлено его биологическими особенностями: интенсивным накоплением органического вещества за короткий период времени и относительно слабым развитием корневой системы. Известно, что для выращивания стабильных урожаев ярового ячменя с высокими показателями качества зерна важно обеспечить растения элементами питания с самого начала вегетации за счет внесения минеральных удобрений. Эффективному и рациональному применению удобрений, оптимизации сроков, способов и доз уделяется особое внимание. В статье представлены экспериментальные данные по вегетации и урожайности зерна ярового ячменя в зависимости от применения разных норм минеральных удобрений и способов основной обработки почвы.

Authors: Alnawas Anwar , Alharbi Hasanein , M. Hassoun Al-Jawad Mohammed
Published: January 2025

Drug addiction remains one of the key problems, which troubles each nation nowadays. Though social and economic factors have been contributing to its escalation significantly, recently in recent years a marked rise with drug addiction has witnessed in Iraq. Governments and societies are therefore working hard to find ways of counteracting this trend. Notably, social media networks have become major conduits of the dissemination sensitization about the risks involved in substance abuse addiction as well as consequences that are faced by drug abusers users. On the other hand, there are no studies analyzing user’s sentiment regarding drug addiction on social media in Iraq. This paper offers a new approach to fill this gap by presenting an analytical framework for identifying such sentiments of people from posts published on different popular platforms including Facebook and Twitter. In order to achieve this, a new dataset was generated from one of the relevant Facebook pages and comprised three distinct levels of user engagement data. Our goal is to create a direct connection between the research objectives and practical applications which can benefit society. This study’s results contribute significantly to the understanding of sentimental movements regarding drug addiction and affect public perceptions on this significant problem. This study makes contributions to such fields are sentiment analysis, social media research and public health by revealing the complex interaction of social media itself, user’s feelings towards it or even drug addiction in Iraq. The new approach to analysis of multi-level user engagement data and offers an evidence based solution for dealing with the challenges presented by drug abuse in society. Using a neural network algorithm, the classification model developed has shown excellent performance with an accuracy rate of about 91%.
Designing Face Detection Systems with Gray Wolf Optimization

Published: January 2025

The main objective of this paper project was to create a state-of-the-art face identification technique that can handle the various difficulties caused by changes in illumination, occlusions, and facial emotions. Face detection is a cornerstone of computer vision, facilitating diverse applications ranging from surveillance systems to human-computer interaction. Throughout this paper, the comprehensive exploration of advancing face detection methodologies has been undertaken, culminating in developing and evaluating a novel approach. The challenges posed by variations in facial expressions, lighting conditions, and occlusions necessitated a multifaceted solution. Our proposed method, which consists of interconnected steps, works quite well to overcome these challenges. Using deep learning architectures to increase feature extraction and discrimination was beneficial in the initial stage of fine-tuning Residual Networks (ResNet-50) to serve as the Region-based Convolutional Neural Network (Faster R-CNN) framework classifier. The process of gradually optimizing thresholds, such as batch size, learning rate, and detection threshold, involved using the Gray Wolf optimization technique (GWO). The conversion process was accelerated and improved overall detection process efficiency and accuracy using a clever fusion of machine learning and metaheuristic optimization techniques. A key component of our methodology is the careful data processing, which was necessary to ensure. The suggested method was carefully examined on a particular dataset, and the 94% training accuracy that was attained together with an identical test dataset accuracy highlights the method's resilience. These findings support the effectiveness of our approach in reducing false positives and negatives, resulting in unmatched recall and precision in the detection system. The discovery has significant significance as it can potentially improve face detection systems' performance and reliability in various real-world applications, such as human-computer interaction and surveillance. Convolutional neural networks, deep learning architectures, and metaheuristic optimization approaches were synergized to produce a new and reliable solution.

A síndrome de roubo coronário-subclávio (SRCS) é uma causa rara de isquemia miocárdica após cirurgia de revascularização miocárdica (0,1% a 6%), sendo a principal etiologia a aterosclerose. A SRCS possui incidência na população com doença aterosclerótica de 3%. A existência de doença vascular periférica é o melhor fator preditivo da ocorrência da SRCS. A prevalência é difícil de determinar, uma vez que muitos doentes não apresentam sintomas devido ao desenvolvimento de uma rede colateral suplementar. O tratamento é centralizado na correção da estenose artéria subclávia. A revascularização endovascular das artérias subclávias tem apresentado ao longo das últimas décadas taxas de sucesso técnico (97%) e de permeabilidade (taxa de permeabilidade, aos 5 anos, de 89-95%) excelentes, comparáveis com a da revascularização cirúrgica, tendo a vantagem de ser uma técnica minimamente invasiva, com taxas de morbimortalidade (4,5%) inferiores às da cirurgia e de se associar a internamento mais curto, bem como recuperação mais rápida. Nós relatamos um caso de angina pectoris, em paciente pós CRM, tendo como etiologia a SRCS e como foi realizado o diagnóstico e conduta do caso.
Health challenges and coping mechanisms of female street children in Harare, Zimbabwe
Authors: Mhuru Dennis , Mutekwe Paddington
Published: January 2025

This study explored the health challenges and coping strategies of female street children aged between 8 and 15 years. Existing studies on street children have generally viewed the problems faced by both girls and boys. This paper contributes to this body of knowledge by investigating the phenomenon of street children from a gender perspective, specifically focusing on female street children in Harare, Zimbabwe. A qualitative approach was employed, and data were collected through 17 in-depth interviews. The findings indicate that female street children face challenges such as a lack of sanitary pads, poor diet, inadequate hygiene, and substandard living conditions, all of which often result in mental health problems. To cope with these challenges, female street children engage in drug use, undertake marginal work, scavenge, beg, and rely on donations from NGOs and the government. The findings also revealed that they use clothes as facemasks and consume lemons as coping mechanisms against health needs induced by COVID-19.
Shedding Light on the Origin of the Broken Misaligned Circumtriple Disk around GW Ori
Authors: Smallwood Jeremy L. , Lubow Stephen H. , Martin Rebecca G. , Nealon Rebecca
Published: January 2025

We revisit the origin of the observed misaligned rings in the circumtriple disk around GW Ori. Previous studies appeared to disagree on whether disk breaking is caused by the differential precession driven in the disk by the triple star system. In this Letter, we show that the previous studies are in agreement with each other when using the same set of parameters. But for observationally motivated parameters of a typical protoplanetary disk, the disk is unlikely to break due to interactions with the triple star system. We run three-dimensional hydrodynamical simulations of a circumtriple disk around GW Ori with different disk aspect ratios. For a disk aspect ratio typical of protoplanetary disks, H/r ≳ 0.05, the disk does not break. An alternative scenario for the gap's origin consistent with the expected disk aspect ratio involves the presence of circumtriple planets orbiting GW Ori.
Detection of O25b-ST131 clone in extended spectrum beta-lactamase-producing E. coli from urinary tract infections in Mexico

Published: January 2025

Introduction: Escherichia coli has emerged as an important pathogen in urinary tract infections (UTIs) due to the rapid acquisition of antibiotic resistance genes. This enhances the ability of E. coli to colonize and creates therapeutic challenges within the healthcare system. This study aimed to identify the extended spectrum beta-lactamase (ESBL) and O25b-ST131 pandemic clones in E. coli isolated from two hospitals in Mexico.
Methodology: Bacterial identification and antibiotic susceptibility tests were conducted using the VITEK 2 system. The ESBL and plasmid-mediated quinolone resistance (PMQR) genes were identified by polymerase chain reaction (PCR). E. coli genotyping was carried out by the phylogenetic group analysis and O25b-ST131 identification.
Results: A total of 103 unique E. coli clinical isolates were analyzed from a pool of 1,002 strains; 75% obtained from UTIs and vaginal secretions. Multi-resistant antibiotic profiles were observed. Notably, the presence of the aac(6`)lb-cr and qnr genes was associated with 100% ciprofloxacin resistance, when ESBL was present. Additionally, the B2 phylogenetic group was identified, with 23% of isolates belonging to the O25b-ST131 clone.
Conclusions: Our research revealed a 10% prevalence of ESBL, in contrast to global prevalence rates. The resistance profiles suggest that the effectiveness of these commonly used antibiotics in treating E. coli-associated UTIs or vaginal infections has decreased significantly. Excessive use of antimicrobial agents contributes to the regional variation. Our results underscore the importance of monitoring the molecular epidemiology, antibiotic resistance, and transmission dynamics of the O25b-ST131 E. coli clone.

Introduction: Globally, approximately 2.7 million and 2.3 million people living with HIV are co-infected with hepatitis B and C virus, respectively. Relatively, little is known regarding HBV or HCV co-infection in HIV-infected children in Calabar, Nigeria, though the routes of transmission of the three viruses are similar. This study aimed to determine the seroprevalence and risk factors for HBV and HCV among HIV-infected children and young adults attending Paediatric HIV Care and Treatment Centres in Calabar, Cross River State, Nigeria.
Methodology: This was a cross sectional study involving 204 HIV-infected children and young adults aged 1–23 years attending four outpatient treatment centers. Blood samples were obtained and tested for hepatitis B surface antigen (HBsAg) and HCV antibody (anti-HCV antibodies). Seroprevalence and factors associated with HBsAg were analyzed using Chi-square test or Fisher’s exact test. A p-value of < 0.05 was considered significant.
Results: The mean age of the study participants was 13.20 ± 4.39 years. Overall, four study participants were positive for HBsAg, a seroprevalence of 2%, and none was positive for HCV-Ab. All positive study participants were females aged 11 years and above, and belonged to the low and middle socio-economic class, with no vaccination against HBV.
Conclusions: The seroprevalence of hepatitis B infection in this study was low, none of those positive received vaccination against HBV. In view of the public health importance of HBV infection, vaccination against HBV should be extended to children and young adults above 14 weeks of age in Nigeria.

Introduction: Alkhumra hemorrhagic fever virus (AHFV) is a newly discovered virus in the Flaviviridae family. It was discovered in 1995 among animal handlers in Saudi Arabia. AHFV spreads through close contact with infected animals and tick bites. Symptoms range from fever and flu-like symptoms to hemorrhagic manifestations, and rarely, encephalitis. The Saudi Arabian Ministry of Health has reported 604 cases so far. There are no approved vaccines, antiviral therapies, or routine screening systems for AHFV. This lack of preventive measures makes it challenging to predict future outbreaks or re-emergence in endemic regions of Saudi Arabia.
Methodology: We cloned, sequenced, analyzed, expressed, and purified the recombinant AHFV capsid protein (CP) using the PET-28a (+) vector. The CP gene was amplified through reverse transcriptase polymerase chain reaction (RT-PCR) and cloned into a vector. The expression and purification processes were carried out in E. coli.
Results: The sequence of the CP gene was deposited in GenBank (Accession number OR785375) and designated as AHFV-SIAU-1-KSA. Sequence analysis revealed similarities with other AHFV isolates obtained from humans, animals, and ticks. Phylogenetic analysis showed that the AHFV CP gene formed distinct clusters with other AHFV genomes collected at different time intervals. The expressed protein was successfully purified and analyzed by SDS-PAGE.
Conclusions: This study is the first to document the cloning, expression, and purification of the recombinant AHFV CP gene from Saudi Arabia. The purified protein will be used to develop a serological assay for routine screening of AHFV samples in humans, animals, and ticks in Saudi Arabia.
A Correlational Study of Burnout and Mitigating Psychological Factors in Undergraduate Nursing Students
Authors: Horan Kathleen M.
Published: January 2025

Background

Evidence indicates that many nursing students exhibit signs of burnout and consider leaving nursing during nursing school. However, there is scant literature on the extent of this problem or mitigating factors.

Method

Undergraduate nursing students (
n
= 129) participated in a correlational study examining patterns of burnout and Psychological Capital (PsyCap), a four-pronged construct that captures hope, efficacy, resilience, and optimism. Burnout and PsyCap were measured using the Maslach Burnout Survey (MBI-GS) and the PsyCap Questionnaire (PCQ-24). Burn-out prevalence was calculated. Correlations were assessed using MBI-GS subscales and the PCQ-24. Bivariate regressions were used to assess the effects of PsyCap on burnout dimensions.

Results

High levels of exhaustion were identified, with 38.8% of the participants scoring in the overex-tended range, the first stage of burnout. Moderate PsyCap levels were found to be protective against burnout.

Conclusion

Strategies to increase PsyCap in nursing students may enhance well-being and reduce dropout.

The Effects of Practice on Graduate Nursing Students' Objective Structured Clinical Examination Scores
Authors: Linder Shannon , Wiggins Morgan
Published: January 2025

Background

Objective structured clinical examinations (OSCEs) are an important part of the graduate nursing curriculum at The Ohio State University, including in the psychiatric mental health nurse practitioner (PMHNP) program. Despite positive feedback from the OSCE assignments, students often reported experiencing anxiety before the assignments. In 2023, the PMHNP faculty implemented a pre-OSCE practice assignment designed for students to review an initial psychiatric evaluation by interviewing a peer. The authors proposed exposure to the pre-OSCE practice assignment would improve subsequent students' OSCE scores.

Method

Mean OSCE scores were compared using independent samples t test.

Results

No significant differences were found in mean OSCE scores for the group with the pre-OSCE practice assignment and the group without the pre-OSCE practice assignment.

Conclusion

Further exploration is warranted.

Mapping the dynamics of crime against women in India: a spatio-temporal analysis
Authors: Kumari Suman , Kumar Naveen , Sharma Anuradha
Published: January 2025

Women throughout the globe face multiple vulnerabilities. This is due to the popular perception prevailing in the society which sees women as vulnerable or inferior sex. Since times immemorial women have been victims of patriarchy in various forms. Though it is considered that with the coming of 21st century women have become empowered. However, they are still victims and face exploitation both in public and private space. The SDG focuses on ending violence against women and girls by 2030. This study delves into a comprehensive analysis of crimes targeting women across various States and union territories in India spanning a decade, from 2012 to 2021. The research draws upon secondary data sourced from the National Crime Record Bureau. These offenses have been segregated into three main categories: sexual crimes, domestic/dowry-related offenses and other criminal acts. To grasp the patterns, averages over five-year periods have been computed. Additionally, crime intensity has been assessed to gain a holistic view of the situation, complemented by the creation of maps using ARC GIS.
Les « amazoones », des chimères du mouvement antispéciste ?
Authors: Veillard Nolwenn
Published: January 2025

Défini comme un syncrétisme entre le féminisme et l’antispécisme, le courant femelliste propose d’hybrider les deux luttes pour n’en former plus qu’une en faveur de la défense de toutes les « femelles ». Dans le mouvement antispéciste, l’emploi de cette catégorie politique, tout comme l’inscription de ce courant dans des aspirations essentialistes, est loin de faire l’unanimité. Pour mieux comprendre ces tiraillements, l’article revient d’abord sur la généalogie théorique du concept, en parcourant à la fois ses prémisses et ses développements plus contemporains. Puis, en prenant appui sur l’étude de cas d’un collectif militant qui revendique une identité femelliste, l’article met en exergue les appropriations discursives qui sont faites de ces travaux théoriques à l’échelle de l’organisation et de ses militant·es, ainsi que la réception contrastée de ce courant au sein même du mouvement antispéciste.
Humor político en la hipermediatización: el anuncio “la guerra contra la inflación” por parte del presidente argentino Alberto Fernández
Authors: Cialdella Andrea Sol
Published: January 2025

El presente trabajo analiza el rol de lo reidero en la construcción de un acontecimiento en particular: tomamos por caso el discurso presidencial de Alberto Fernández de los días 15 y 18 de marzo de 2022 en el que anunció que su gobierno comenzaría “la guerra contra la inflación”. A partir de este objeto se buscó indagar las modalidades risibles que se produjeron en las redes sociales y medios de comunicación masiva, constituyéndose una circulación hipermediática. Constatamos la hipótesis de que, en la construcción del acontecimiento en las sociedades contemporáneas, se dan complejos procedimientos de apropiación colaborativa por parte de lxs internautas y los medios informativos que editorializan los eventos con sus memes. En las conclusiones respondemos cuáles fueron las características propias del fenómeno, destacando la red social Twitter, en donde proliferaron más abundantemente dichos discursos.
Reflexões sobre jornalismo e algoritmos na ambiência da esfera pública midiatizada
Authors: Zanetti Lucas Arantes , Luvizotto Caroline Kraus
Published: January 2025

Este artigo tem como objetivo caracterizar o jornalismo na ambiência da esfera pública midiatizada, com foco no papel das redes sociais e dos algoritmos no contexto da polarização e da crise da democracia no Brasil. Para isso, utilizamos um conjunto de aportes que vão desde as teorias da midiatização, perpassando pela a esfera pública habermasiana, bem como conceitos da psicologia social, para analisar eventos sociais no Brasil desde 2013, um ano crucial marcado por conflitos e polarização que afetam o debate público atual. Entre diferentes abordagens e análises, nossa proposta é refletir sobre o aspecto comunicativo dos processos no espaço público contemporâneo. Acreditamos que existe uma crise global no conceito de sociedade moderna, que está a ter um impacto negativo na democracia, nos meios de comunicação social e no jornalismo, levando à criação de um espaço público contemporâneo que é dividido, menos racional e mais emocional, moldado pela lógica comunicativa algorítmica das empresas de tecnologia.

Authors: Nigri Veloso Lucas , Salgueiro Marques Ângela Cristina
Published: January 2025

Consideramos o conceito de "cartografia encarnada" como um gesto metodológico e ético para a geração de dados e análise de processos comunicativos-políticos colocados em ato por dinâmicas de participação cidadã, como os movimentos sociais. Articulando epistemologia feminista das vulnerabilidades, noções pós-representacionais de cartografia social e princípios da participação-observante, propomos uma estratégia para mapear condições de possibilidade e performatividades que nos permitem distinguir distintas topografias de participação política. Aplicamos esta abordagem a um estudo de caso sobre o movimento de luta antimanicomial no Brasil, desvendando como a interação entre as vulnerabilidades do cartógrafo e dos participantes abre caminho para inovações em conhecimento social e democracia. Destacamos não apenas os desafios e oportunidades dessa abordagem, mas também seu potencial de desdobrar insights teóricos e conceituais situados, como nosso conceito emergente de "crioulização antimanicomial”.

The Influence of Niobia Additions on Microstructure, Vickers Hardness and Indentation Fracture Resistance of ZTA Ceramic Composites
Authors: Su Nurul Khairunnisa , Rejab Nik Akmar , Johar Banjuraizah , Sktani Zhwan Dilshad Ibrahim , Ahmad Zainal Arifin
Published: January 2025

The effect of small additions of niobium pentoxide (Nb2O5) from 0 to 0.7 wt% on the zirconia toughened alumina (ZTA) ceramics sintered at 1600 °C was studied. Based on the results, the small addition of Nb2O5 was discovered to be able to significantly influence on phase, microstructure, and mechanical properties of ZTA ceramics. The presence of the secondary phase of Nb2Zr6O17 as a square-shaped particle is confirmed by SEM and FESEM-EDX up to 0.5 weight percent (wt.%) of Nb2O5 additions. The addition of 0.3 wt.% resulted in the highest Vickers hardness value of 1500 Vickers hardness (HV). However, it was found that adding Nb2O5 more than 0.3 wt% causes ZTA's hardness and indentation fracture resistance (KIFR) values to decline from 1500 HV to 1438 HV and 4.88 MPa.√m to 4.18 MPa.√m, respectively. Additionally, it was found that when the amount of Nb2O5 added increased, the value for bulk density climbed while porosity reduced.
In-House X-Ray Absorption Spectroscopy Measurement Using X-Ray Diffractometer: Comparison with Synchrotron Facilities
Authors: Saniman Siti Sarah , Omar Muhammad Firdaus
Published: January 2025

X-ray Absorption Spectroscopy (XAS) experiments are usually performed at synchrotron facilities utilizing high-intensity X-ray sources produced by particle accelerators. However, this study showcases an in-house XAS experiment carried out using an X-ray Diffractometer (XRD) system that is typically available in material laboratories. The Rigaku SmartLab XRD was employed and configured for the Bragg-Brentano (BB) measurement mode. 20 keV electron energy is used to energize a molybdenum (Mo) target and produce high-intensity white X-rays via the Bremsstrahlung effect. Several crystals were tested as crystal analyzers for white X-ray dispersion to obtain optimal X-ray intensity and resolution. The detector energy filter is optimized to increase the peak-to-background ratio then the energy dispersion and resolution over the θ/2θ scanning range is determined and evaluated. The performance of the in-house XAS experiment is compared to theoretical calculations and synchrotron data from previous studies by observing resolution and spectrum shape and peak features of deposited Copper (Cu) and Copper Oxide (CuO) samples. Our findings showed that the absorption edges were clearly observed despite the peak broadening and shifting above absorption edge. Furthermore, some peaks were also observed in the XAS spectrum which originated from X-ray fluorescence of elements from both the samples and hardware components.
