Published: October 2024

This study investigated the association between gingival hyperplasia and various systemic diseases and medications. Data from 1055 patients were analyzed, including those with leukemia, pregnancy, diabetes, and those taking medications known to induce gingival hyperplasia (phenytoin, cyclosporine, calcium channel blockers). Results indicated a significantly higher prevalence of gingival hyperplasia in patients with leukemia (40%, 95% CI: 30-50%) and poorly controlled diabetes (25%, 95% CI: 20-30%) compared to the control group (4%, 95% CI: 2-6%). Pregnancy also showed a statistically significant increase in gingival hyperplasia, with prevalence rising from 15% in the first trimester to 25% in the third trimester. Drug-induced gingival hyperplasia was observed in a substantial proportion of patients receiving phenytoin (35%), cyclosporine (25%), and calcium channel blockers (27%). Clinical characteristics of gingival hyperplasia varied depending on the underlying etiology, with leukemia-associated hyperplasia often presenting as severe, generalized, and friable tissue. These findings highlight the importance of considering systemic factors and medication profiles when assessing and managing gingival hyperplasia. Further research is needed to elucidate the mechanisms underlying these associations and to optimize treatment strategies.

Authors:   Capital program manager, Alexandria city public schools, Alexandria city, Virginia, USA, Paspunoori Sampath kumar
Published: October 2024

The relevance of the research topic is due to the increasing complexity of construction projects, stricter requirements for deadlines, quality of work, as well as increased competition in the relevant industry. In the current conditions, traditional management methods often turn out to be ineffective, which leads to deadlines, budget overruns, and a significant decrease in the quality of construction. The purpose of the study is to analyze and systematize ideas about modern models of productivity improvement in construction project management, as well as to assess their potential impact on key performance indicators of projects. Special attention is paid to the formulation of the author's view of the advantages and limitations of specific models. The study revealed contradictions between the need to introduce innovative approaches to working with projects and the conservative practices that have developed in the industry. In addition, it is advisable to point out the discrepancy between the pace of development of digital technologies and the speed of their adaptation in the construction sector. It is concluded that integrated models combining elements of flexible methodologies, digital developments, and Lean approaches are the most effective. The role of digital twins, predictive analytics, and blockchain in improving productivity in this area is particularly emphasized.

Authors: Ferrer Maxime , Iribarren Iñigo , Renningholtz Tim , Alkorta Ibon , Trujillo Cristina
Published: October 2024

Carbon capture and utilisation (CCU) technologies offer a compelling strategy to mitigate rising atmospheric carbon dioxide levels. Despite extensive research on the CO2 insertion into epoxides to form cyclic carbonates, the stereochemical implications of this reaction have been largely overlooked, despite the prevalence of racemic epoxide solutions. This study introduces an in silico approach to design asymmetric frustrated Lewis pairs (FLPs) aimed at controlling reaction stereochemistry. Four FLP scaffolds, incorporating diverse Lewis acids (LA), Lewis bases (LB), and substituents, were assessed via volcano plot analysis to identify the most promising catalysts. By strategically modifying LB substituents to induce asymmetry, a stereoselective catalytic scaffold was developed, favouring one enantiomer from both epoxide enantiomers. This work advances the in silico design of FLPs, highlighting their potential as asymmetric CCU catalysts with implications for optimising catalyst efficiency and selectivity in sustainable chemistry applications.

Authors: Fatma Yulia , Soni  , Mikdad Amseno
Published: October 2024

Cryptography is a data security technique by encoding data that is to be kept secret so that the original meaning of the data can no longer be understood. SIMON and SPECK are modern cryptographic algorithms issued by the National Security Agency (NSA). SIMON and SPECK are said to be algorithms that are known for their efficiency and strong security. This research will compare the performance of the SIMON and SPECK algorithms in securing digital images. Comparisons were made by testing time performance, changes in file size, and the level of randomness of image files using the Unified Average Changing Intensity (UACI) and Number of Pixels Change Rate (NPCR) metrics. The research results show that the average encryption and decryption time required by the SIMON algorithm is greater when compared to the SPECK algorithm. The image file size resulting from encryption using the SIMON and SPECK algorithms both increased by 24% from the original image. The level of randomness of the resulting image based on the UACI value obtained using the SIMON algorithm was found to be an average of 19.65%, while the UACI value obtained using the SPECK algorithm was an average of 20.94%. This shows that there is a significant change in intensity between the original image and the encrypted image. However, not all pixels in the encrypted image change when compared to the original image, this is shown by the NPCR value obtained from the SIMON and SPECK algorithm encrypted image, with average results of 49.98% and 50.17%.

Authors: S. Bandjar Budhyawan , Rindarjono Mohammad Gamal , Prihadi Singgih
Published: October 2024

STEM and Project-Based Learning (PjBL) learning models have been applied to support 21st century learning. However, no empirical evidence has been found to reveal the combined effectiveness of the two models. This study aims to determine the effectiveness of STEM, Project-Based Learning (PjBL), and lecture learning models in improving critical thinking skills. The research was conducted at SMA Negeri 8 Ternate City, North Maluku Province, involving 64 students divided into three classes studying Indonesian natural resource management. A concurrent embedded strategy combining quantitative and qualitative data collection was used. Initial test data indicated reliability at 0.76, with normality tests for the STEM model at 0.08, the PjBL model at 0.13, and lecture learning at 0.14, all showing normally distributed data. The homogeneity test showed homogeneous data with a value of 1.097. The balance test using one-way ANOVA indicated balanced initial abilities (Fhitung 2.52 Ftabel 3.14). Results demonstrated that by applying the STEM and PjBL learning models, students achieved proficiency in critical thinking skills. Final test data, including normality tests, one-way unequal ANOVA, and post-ANOVA tests, showed significant improvement in critical thinking skills. The STEM model and PjBL model were both effective with no significant differences between them, while both differed significantly from the lecture learning model. The results suggest that both STEM and PjBL models are effective in enhancing critical thinking skills. To address the shortcomings of traditional lecture methods, educators should consider integrating STEM and PjBL approaches into their teaching practices.

Authors: Muiz Abdul Raqib  , Yaser ALAIWI  , Ahmad Jundi
Published: October 2024

This study investigates the use of titanium dioxide (TiO2) nanofluids to enhance the thermal performance of shell and tube heat exchangers. A comparative computational fluid dynamics (CFD) analysis is conducted using water and a 0.5% TiO2 nanofluid. The heat exchanger is modelled using computer-aided design (CAD), with dimensions closely resembling commercial units. The CFD model is validated through a grid-independence study, with a mesh of 4,112,679 elements yielding grid-independent results. The key findings show that the 0.5% TiO2 nanofluid increases the cold fluid outlet temperature by 11.44% compared to water (36.04°C vs. 33.63°C). The average heat transfer coefficient is enhanced by 12.3% when using the nanofluid. The CFD results are consistent with experimental data, with a maximum deviation of 4.2% in the outlet temperatures. This study demonstrates the successful integration of TiO2 nanofluids with an optimized shell and tube heat exchanger design. The novelty lies in the application of nanofluids to improve the thermal performance of industrial heat exchangers. The presented methodology, combining CAD modelling and CFD analysis, provides a foundation for further optimization and experimental validation of nanofluid-enhanced heat transfer systems.

Authors: Altimemy Muhannad , Ibrhim Ahmed Khalid , Hassan Hassan Raheem , Hayawi Mustaf Jabbar
Published: October 2024

As global power demand increases, hydropower plants often must operate beyond their optimal efficiency to meet grid requirements, leading to unstable, high-swirling flows under various load conditions that can significantly shorten the lifespan of turbine components. This paper presents an in-depth computational study on the performance and dynamics of a pump-turbine operating under 80% partial load, focusing on the formation and impact of vortex ropes. Large Eddy Simulation (LES) was utilized to model the turbulent flow, revealing complex patterns and significant pressure fluctuations. A pronounced straight vortex rope was identified in the draft tube, maintaining its trajectory and core size consistently, profoundly affecting flow characteristics. Pressure fluctuations were observed at various cross-sectional planes, with peaks and troughs primarily near the runner, indicating areas prone to instability. The standard deviation of pressure fluctuations ranged from 4.51 to 5.26 along the draft tube wall and 4.27 to 4.97 along the axial center, highlighting significant unsteady flow. Moreover, the frequency corresponding to the highest amplitude in pressure coefficient spectrographs remained consistent at approximately 9.93 to 9.95, emphasizing the persistent influence of vortex rope dynamics. These dynamics affected power generation, which was approximately 29.1 kW, with fluctuations accounting for about 3% of the total generated power, underscoring the critical impact of vortex rope formation on the performance and operational stability of pump-turbines under off-design conditions. This study provides essential insights vital for enhancing the design and operational strategies of these turbines, ensuring more efficient and reliable energy production in the face of increasing power demands.

Authors: Jie C Y , Ali N Mat
Published: October 2024

The COVID-19 pandemic has made countries and organizations around the world to revise their business operations. Some countries took a step further by executing Movement Control Order (MCO) to reduce the spread. During MCO like Malaysia, all non-essential businesses were closed, interstate travel was prohibited, and purchasing of daily needs were limited. This pandemic had rendered Malaysian homebound. The majority of students who are still staying in hostels were not allowed to return home. To prevent direct contact, face-to-face classes were not possible to conduct. Alternatively, online learning was implemented for teaching and learning purposes for safety reasons. Sadly, most were not prepared for online learning due to the unexpected abruptness of COVID-19. Many issues were raised but little guidelines were available to be followed. Therefore, this paper aimed to identify the challenges of online learning, i.e institutional readiness, students’ difficulties, and teachers’ dilemma. Findings would assist organizations to adopt necessary actions for better education. This study was conducted by reviewing previous and recent literature from several journals, conferences, and news focusing on tertiary education. In addition, the study has proposed that organization should adopt the ADKAR framework introduced by Hiatt for transformation and change towards better online transition. The use of Learning Management System (LMS), infrastructure improvements, teaching methods and parents involvement were also crucial factors for online education success.

A Study of Word Bigrams for Pseudo-relevance Feedback in Information Retrieval
Authors: Dang Edward Kai Fung , Luk Robert Wing Pong , Li Qing
Published: October 2024

Traditional information retrieval models mostly adopt a term independence assumption and are based on single terms or unigrams. Past efforts have attempted to go beyond this assumption, such as by using contiguous terms (i.e. word n-grams) or terms appearing in proximity. One such approach employs pseudo-relevance feedback (PRF) in an extended BM25 model, with an expanded query containing bigrams and proximity word pairs besides unigrams. However, the benefit of this approach over the traditional unigram PRF remains inconclusive. We speculate the uncertain effectiveness of bigram PRF in this past work is due to: (1) The new bigrams obtained from the expanded query may be formed by pairing unigrams drawn from different documents. These are potentially noise instead of relevant concepts; (2) The collection statistics of n-grams needed to calculate the document ranking functions, such as their document frequency, is not available in retrieval. Only estimates of these quantities are used instead. We suggest that these issues may be overcome by extracting word n-grams as single units in query expansion, and employing a document index that contains both unigrams and word n-grams. We demonstrate the approach for the case of bigram PRF in an extended BM25. Retrieval experiments are conducted on a range of standard test collections. For the majority of tested collections, the difference between values of the evaluation metrics (Mean Average Precision and the precision-oriented NDCG@20) obtained by our bigram PRF and the unigram PRF baseline is not statistically significant. Thus, our bigram PRF fails to improve over unigram PRF robustly across collections. An analysis of our results reveals ‘query drift’ due to bigram query expansion terms that represent too-broad topics as a cause for the failure of our approach.

In recent decades, the state has been tasked with the effective management of natural resources, among which land resources hold particular importance due to the necessity of their rational use and sustainable development. The value of land resources and their indispensable role in ensuring the socio-economic development of the country is most clearly reflected in the state’s tax policy, specifically in land taxation. The amount of land tax depends on the cadastral value, which is often subject to methodological shortcomings and challenges. This study, using the Belgorod Region as a case study, proposes an algorithm for determining the cadastral value of land plots within gardening and horticultural non-profit partnerships, taking local factors into account. To determine the specific indicator of cadastral value (SICV) of land plots, a linear regression model was developed. The results, tested for homoscedasticity, confirmed the model’s adequacy and reliability. The findings showed that the cadastral value decreased by an average of 12.2% compared to the current results of the state cadastral assessment in the Belgorod Region, highlighting the influence of local factors and the importance of considering them in the cadastral evaluation of the land plots in question.

In this current paper, we developed a new predator-prey model accompanying delay based on the earlier works. By applying inequality strategies, fixed point theorem, and a suitable function, we got new necessary conditions for the existence, uniqueness, nonnegativeness, and boundedness of the solution to the developed delayed predator-prey model. The bifurcation behavior and stability nature of the defined delayed predator-prey model were investigated by using stability and bifurcation theory of delayed differential equations. We have modified the Hopf bifurcation's appearance time and stability domain by building two distinct hybrid delayed feedback controllers for the delayed predator-prey model. The time of Hopf bifurcation appearance and stability domain of the model were explored. Matlab experiment diagrams were given to support the learned important results. The derived outcomes in this paper were original and have significant theoretical implications for maintaining equilibrium between the densities of the three species.
“I just need respect as a man that's all”: dynamics of respect and physical intimate violence among African men in Johannesburg
Authors: Rowlands Emmanuel
Published: October 2024

Respect serves as a protective factor for the quality of intimate relationships. In the current paper, the potential loss of respect for the male partner as a predictor for the female partner's use of physical intimate violence was examined. The analysis drew upon the perceptions and experiences of 25 African men who sought medical assistance following episodes of physical intimate violence. Additional perspectives from five specialists who worked with the victims were also included. Findings demonstrate that the quality of a relationship is positively predicted by mutual respect toward partners. The loss of respect for the male counterpart is positively predicted as a risk factor for the female partner's use of physical intimate violence. The results and their implications are discussed within the scope of the related literature.
Ficción satírica y desengaño en los Sueños de Quevedo
Authors: Mestre-Zaragozá Marina
Published: October 2024

El desengaño es la finalidad ampliamente proclamada y reivindicada de los Sueños de Quevedo. Este trabajo busca poner de manifiesto el lugar central que ocupa en cuanto a la construcción de cada relato y del conjunto de todos ellos, así como las modalidades según las cuales opera en los lectores. Según la interpretación propuesta, los Sueños son el adalid de un desengaño específicamente quevediano, que marcará una inflexión determinante en la manera en la que el Siglo de Oro contempla la ejemplaridad, entre la ejemplaridad abierta propuesta y defendida por Cervantes y la ejemplaridad unívoca y cerrada que construye el desengaño quevediano a partir de una sátira corrosiva, la cual opera tanto a nivel diegético como en la paradójica y eficaz relación que el autor establece con su lector.
El Desengaño mayor o las voces de doña María de Zayas
Authors: Treviño Elizabeth
Published: October 2024

La noción del desengaño barroco en la narrativa de María de Zayas adquiere una dimensión única. En el Sarao y entretenimiento honesto, conformado por las dos colecciones de novelas cortas de su autoría (1637 y 1647), vemos a la escritora áurea introducirse —acaso entrometerse— en los relatos a través de dos facetas de la autora que desengañan, cada una con una voz y un propósito particular. En conjunto, difuminándose en ocasiones, ambas Zayas confeccionan un Desengaño mayor, un discurso supratextual que revela su propia «poética del desengaño».
‘Que cuanto el mundo ofrece es sombra, es viento’. Lirismo y defección en el Desengaño de amor en rimas de Pedro Soto de Rojas
Authors: Vila Juan Diego
Published: October 2024

La reescritura del mito de Dédalo e Ícaro en tres sonetos del Desengaño de amor en rimas del granadino Pedro Soto de Rojas permite reconocer, tras el trabajo de metaforización de la voz lírica en tales figuras, un sendero ejemplar de lectura en el cual el poeta descubre el proceso anímico de engañarse y desengañarse. Esta tensión anímica, ligada al ideario neoestoico que informa el cancionero, se despliega en la primera sección del corpus en la cual la caída, pérdida y error amoroso terminarán contraponiéndose a la sección conclusiva donde señorea la regeneración ascética. Soto encuentra en el sino duplicado del incauto hijo y del desafortunado padre las claves téticas de una antropología poética en clave cristiana.
Erreur et vérité de l’enfance selon Malebranche : quelle pédagogie malebranchienne ?
Authors: Geny Vincent
Published: October 2024

On connaît la mise en garde de Nicolas Malebranche contre les dangers de l’enfance. Ce que l’on méconnaît, en revanche, assez souvent est le fait singulier que la Première partie du Livre second de la Recherche de la vérité consacré aux erreurs de l’imagination se clôt par un Avis pour bien élever les enfants dans lequel l’oratorien défend une pédagogie fondée sur le principe, paradoxal et tout à fait contraire à un certain découpage des âges de la vie, selon lequel « Les plus petits enfants ont de la raison aussi-bien que les hommes faits, quoiqu’ils n’aient pas d’expérience ». Pourquoi Malebranche fait-il reposer ainsi le problème de l’enfance — mais aussi, nous le verrons, sa solution pédagogique — non pas sur le manque de raison, comme on aurait pu l’attendre de la part d’un philosophe cartésien dit « rationaliste », mais sur un certain manque d’expérience ?
