Chemical investigation of the crude methanolic extract of the leaves of Citrus Paradisi resulted in the isolation of two known compounds (isolated for the first time from the leaves) namely citracridone II and apigenin. The structures of these compounds were established by using various spectroscopic methods including 1D NMR (1H NMR and 13C NMR) and 2D NMR (COSY, HMQC and HMBC) in conjunction with mass spectrometry and by the comparison with literature data. Acridone alkaloids isolated from Citrus medica and others species of genus Citrus appear to be useful as chemotaxonomic markers in Citrus. The crude extract was evaluated for its antibacterial activity against nine strains and antifungal activity against four yeasts using the MHA and SDB methods. The tested treatments showed Significant antibacterial activity against 2 bacterial strains tested with MBC/MIC (Ratio used to determine bactericidal or bacteriostatic activity) equal to 2 (< 4), and Significant antifungal activity against 2 yeast strains tested with MFC/MIC (Ratio used to determine fungicidal or Fungistatic activity) equal to 2 (≤ 4).
The increasing heterogeneity of services in next-generation wireless networks has intensified the need for efficient radio resource allocation mechanisms capable of satisfying diverse Quality-of-Service (QoS) requirements. Applications associated with enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), and massive Machine-Type Communications (mMTC) impose conflicting demands in terms of throughput, latency, reliability, and fairness, making resource management a challenging task under limited radio resources. Conventional scheduling algorithms and standalone learning-based approaches often struggle to adapt effectively to dynamic channel conditions and stringent QoS constraints. This paper proposes a hybrid optimization and reinforcement learning–based resource allocation framework for QoS-aware next-generation wireless networks. The proposed framework integrates an optimization module implemented in MATLAB with a reinforcement learning–based scheduling mechanism deployed within the NS-3 simulation environment. The optimization stage provides structured guidance for resource allocation under predefined system constraints, while the reinforcement learning component dynamically refines scheduling decisions based on real-time network feedback. This hybrid design aims to improve adaptability, convergence behavior, and overall QoS performance. The proposed framework is evaluated through extensive simulations using realistic traffic models and network parameters. Performance is assessed using key QoS metrics, including throughput, end-to-end delay, packet loss ratio, spectral efficiency, and fairness. Simulation results demonstrate that the hybrid framework consistently outperforms conventional scheduling algorithms and standalone learning-based schemes across multiple performance metrics, highlighting its effectiveness in managing heterogeneous traffic demands. The results confirm that combining optimization techniques with reinforcement learning provides a robust and scalable solution for QoS-aware resource allocation in next-generation wireless networks.
This study aimed to assess the implementation of Output-Based Budgeting (OBB) reforms and their implications for the performance of the public sector in Zambia. The implementation of Output-Based Budgeting (OBB) in Zambia faces significant challenges that impact transparency, accountability, and resource allocation. Thus, the study examined the influence of OBB on transparency, accountability, service delivery, and governance outcomes. The study employed a convergent parallel mixed method design by combining a structured survey of public officials, key informant interviews, and quantitative analysis of Yellow Book budget and output data for selected ministries: Finance, Health, Education, Local Government, Agriculture, and Fisheries & Livestock, over the period 2021–2024. The results revealed that OBB has considerably strengthened transparency and accountability, particularly in Education and Health, where execution rates were high and performance information is more systematically reported and discussed through inclusive budget structures. OBB provided a clear link between budgets and measurable outputs and measurable outputs, for instance, the Grades 1 and 4 numeracy and several health output indicators reached or exceeded targets in later years, confirming that resources are increasingly tied to clearly defined programmes and results. However, significant gaps remain. Grade 9 completion persistently fail short of ambitious targets despite near full budget execution in Education, while Agriculture (Livestock) exhibited lower execution and volatile, often weak achievement ratios, indicating the limits of OBB when there are binding structural constraints, funding shortfalls, and capacity gaps. Qualitative results reinforce these patterns: respondents acknowledged improvements in visibility of expenditure, performance orientation, and internal accountability, but emphasise delayed fund releases, inadequate resources, technical capacity constraints, data inaccuracies, and weak monitoring frameworks as major constraints, especially for sectors that are not better-resourced. The study concludes that OBB in Zambia is conceptually sound and has delivered tangible gains in transparency and selected performance areas, but its overall effectiveness is uneven and limited by institutional and operational challenges. Key recommendations include improving capacity for programme design, M&E and data management; strengthening budget credibility and predictability of releases; enhancing integration and use of performance information in decision-making; and deepening stakeholder engagement and oversight at both central and local government levels. Key words: Output-Based Budgeting; Public Financial Management; Transparency and Accountability; Sector Performance; Zambia.
Effect of Project Kickbacks on Quality Delivery in Construction Projects: An Engineering–Policy Case Study of Cross River State, Nigeria Apeh Ahmed Monday¹* (ORCID: 0009-0001-6647-9283) Ben Ngene² ¹Department of Civil Engineering, Michael Okpara University of Agriculture, Umudike, Abia State, Nigeria ²Department of Civil Engineering, Michael Okpara University of Agriculture, Umudike, Abia State, Nigeria *Corresponding Author: apehm36@gmail.com Abstract Project kickbacks represent a significant governance challenge that undermines quality delivery in public construction projects, particularly in developing economies. This study investigates the effect of project kickbacks on engineering performance and policy compliance in selected construction projects in Cross River State, Nigeria. Key engineering indicators assessed include material compliance, workmanship quality, cost variation, and structural performance, alongside procurement and contract administration practices. The findings reveal that kickbacks adversely influence contractor selection, weaken adherence to technical specifications, and reduce the effectiveness of construction supervision. These practices result in premature defects and increased lifecycle costs. The study recommends strengthened technical audits, transparent procurement systems, and strict enforcement of regulatory frameworks to enhance construction quality and infrastructure sustainability.

Prostate cancer is a common cancer with high histological heterogeneity influencing the prognosis and management. Conventional acinar adenocarcinoma represents the most common histological form; however, some rare variants have been described, including foam cell adenocarcinoma, which represents an unusual variant of acinar adenocarcinoma, first described by Epstein in 1996. The available data regarding its clinically pathological characteristics and prognosis remain limited. We report the case of a 62-year-old patient with prostatic adenocarcinoma with foam variant diagnosed at a metastatic stage. The anatomopathological study highlighted a glandular proliferation composed of cells with abundant and foamy cytoplasm, associated with often pycnotic nuclei, which can constitute a diagnostic trap due to their sometimes slightly atypical cytological appearance. The clinical and histological data and therapeutic management modalities are detailed. This observation highlights the rarity of this histological variant and the importance of its recognition by pathologists, in order to avoid an underestimation of the tumor grade and a therapeutic delay. Knowledge of the morphological characteristics of prostatic foam cell adenocarcinoma is essential to ensure accurate diagnosis and appropriate oncological management.
Optimizing transmission power in Wireless Body Area networks (WBANs) is critical for balancing energy efficiency with link reliability. This paper addresses the challenge of regulating the Received Signal Strength Indicator (RSSI) under highly dynamic channel conditions caused by body posture changes. We propose a robust Indirect Adaptive control framework, comparing two methodologies: Model Reference Adaptive Control (IMRAC) and Adaptive Pole Placement Control (APPC). To overcome the ill conditioning Caused by non -coprime polynomials in the full-order plant model, we introduce a novel implementation using a controllable reduced- order model. The control laws utilize Recursive Least Squares (RLS) with a forgetting factor for real-Time parameter tracking. Simulation results demonstrate that the APPC strategy yields superior performance, achieving a Mean Squared Error (MSE) of 0.09dBm compared to 0.52dBm for IMRAC. The proposed reduced-order APPC offers a computationally efficient and robust solution for stabilizing WBAN links against severe motion artifacts.
In a previous article entitled "How to Generate New Mathematics" [1,2,3], We have demonstrated that the statistical numerical theory known as Cairo Techniques is capable of answering and solving almost all partial differential equations in classical and quantum physics, as well as in pure mathematics, probability, and statistics, such as: 1- Is the Schrödinger equation of 1927 adequate to describe the wave function of quantum mechanics or its square? 2- Is it true that Einstein's theory of special and general relativity are incomplete and misleading? 3- How to generate new mathematics? 4- What are the foundations of the theory and practice of artificial intelligence? 5- What is the theory and practice of audio rooms? 6- What is the theory of everything? 7-Why is information theory, which underlies the six previous topics, still in its infancy? …etc. In this article, we delve deeper into the generation and genesis of new mathematics, focusing on the following bold, urgent, and pressing questions: 1-Can we find link between Einstein's general relativity in 1915 and Schrödinger's quantum mechanics in 1927? Furthermore, can it be proven that these two theories are in fact one and the same? 2-What is the truth of the Planck length Lp = (ℏG/c³)¹/²? 3. Does negative diffusion exist? 4. Is the heating curve of a given metallic mass identical regardless of its geometric shape? 5- Is it impossible for a nuclear power plant reactor to turn into a nuclear bomb? 6- Is time discrete and not continuous? What are the secrets of Cairo techniques? 7. What is the most disastrous theory in history? Is it still in use? 8-Did Einstein resort to dubious occult practices to develop his theory of relativity? 9- What is the truth about artificial intelligence? Thanks to the Cairo technique and the resulting B matrix chains, we arrive without hesitation at the exact answer to these nine questions: yes. Finally, we explain: What exactly are the secrets of spacetime discretization and those of the Cairo techniques, and what happens when both are mastered? In reality, the answer to the nine questions above is not complicated, but as simple as you might imagine, and that is the subject of this article. Finally, it should be clarified that this article is not intended to minimize the major contributions of great physicists such as Einstein, Schrödinger, Heisenberg, Minkowski, Hilbert, and Rieman, among others, but rather to address the main limitations of their theories, where applicable. In reality, the answer to the nine questions above is not complicated, but as simple as you might imagine, and that is the subject of this article.

Effective circulation and wayfinding are fundamental to functional, safe, and inclusive public buildings. This study investigates design strategies and interventions to enhance circulation and wayfinding in two representative public buildings in Port Harcourt. Port Harcourt International Airport (New International Terminal, Omagwa) and the Rivers State Secretariat Complex (Point Block & Secretariat buildings). Combining literature on environmental wayfinding, evidence-based design, and a contextual analysis of the selected buildings. Using a mixed-methods approach (documentary analysis, site observations, and precedents from wayfinding literature), this paper identifies principal circulation bottlenecks, signage and information gaps, and proposes a layered wayfinding strategy tailored to Port Harcourt's built context. Recommendations cover spatial layout changes, signage hierarchy, color and graphic systems, universal accessibility, and digital wayfinding integrations. Findings demonstrate that modest but systematic interventions applied at the architectural, graphic, and operational levels can significantly reduce wayfinding time, user stress, and operational inefficiency in high-use public buildings. Keywords: Wayfinding, circulation, signage, Port Harcourt, airport, government complex, accessibility, environmental design, cognitive mapping.
In Nigeria, maternal and perinatal mortality are a significant issue in the public health, which is further complicated by the poor integration between reporting, reviewing, and responding systems, as well as the fragmented and paper-based nature of such surveillance. This research conceived and put into place a Maternal Risk and Death Reporting System to help facilitate organized, mobile-enhanced workflows of maternal and perinatal mortality surveillance and response in low-resource locations. It was created as a modular web and mobile solution that employs role-based access control, secure data management, automated alerts, and standardized maternal and perinatal death classification which is in compliance with international standards. The structure was in a layered client-server architecture that isolated user interfaces, backend services and data storage to be maintainable and scalable. Scenario-based simulation and functional testing demonstrated that the system has the ability to record maternal risk factors, activate alerts on high-risk cases, facilitate structured audit documentation, as well as implement access controls across user domains. The research offers a scalable technical basis to enhance maternal surveillance processes and accountability, and it assists in pilot implementation and expansion in the future.

The subject of this paper is the development of a macro-equality index and a strategic frame work to monitor its trends and differentials, with an example of application for the EU countries. Previous researches in this respect concerned mainly with micro-equality indices, and macro equality differentials measured only by comparisons of micro- equality indices across subunits. In this paper a single maco-equality index is used to measure equality across different subunits, which is the first of its kind in this field. The methodology used is based on the correlation coefficient statistic of the percent values of the concerned variable, which we discoverred to be the same for all units, provided that the number of subunits per unit is equal. Accordingly, we developed an equation for a macro equality index (MEI) as: MEI = SM - SSD, where SM is the mean of the percent values of the concerned variable, we defined it as Standardized Mean; and SSD is the standard deviation of the percent values of the variable, we defined it as Standardized Standard Deviation. As for the strategic monitoring we developed a system of two models: the strategic monitory model, which describes the equality strategy across subunits or through time; and an EXCEL worksheet model to facilitate macro-equality monitoring through time. We applied this work for the Europian Union Countries on human development indices data from the UN, 1025 retrospective data, for the years from 2010 to 2014.
The rapid escalation of criminal activities underscores the urgent need for intelligent recognition systems capable of accurately identifying suspects in real-world scenarios. To address these challenges, this research proposes an optimized hybrid framework that integrates YOLO (You Only Look Once), Convolutional Siamese Networks, and Graph Neural Networks (GNNs) for criminal recognition. The YOLO architecture is employed to perform robust and real-time face detection, ensuring precise localization of suspects across unconstrained environments. Subsequently, a convolutional Siamese network is utilized to extract discriminative feature embeddings and compute similarity measures between face pairs, thereby enhancing recognition accuracy across diverse intra-class variations. Furthermore, the incorporation of GNN enables modeling of relational dependencies among detected individuals, exploiting co-offender patterns and contextual associations to augment classification performance. To optimize feature selection and reduce redundancy in the hybrid model, this work employed principal component analysis (PCA) for dimensionality reduction and the L1 regularization technique. The system will be trained and evaluated using benchmark datasets labelled faces in the wild (LFW), supplemented with crime-related facial datasets to validate robustness. Anticipated contributions include the demonstration of improved recognition accuracy, precision, and F1-score over state-of-the-art models. The result of the experiment revealed the hybrid model to emerge as the best model with an accuracy of 99% even when compared with some of the state-of-the-art algorithms on criminal recognition.
Law No. 10/010 of April 27, 2010, relating to public procurement, as well as Law No. 15/012 of August 1, 2015, establishing the general legal framework for hydrocarbons, have instituted the call for tenders as the primary method for both the awarding of public contracts and the allocation of hydrocarbon rights. Although these two procedures share similarities, they also contain distinct differences. This study analyzes the disparities between the bidding process in public procurement and that of hydrocarbon rights allocation in terms of advertising requirements, selection criteria for the successful candidate following the competitive process, and the institutional framework responsible for applying these two bidding procedures as prescribed by the aforementioned laws. Keywords: Awarding – Hydrocarbon rights – Public procurement
This study falls within the fields of sociolinguistics and glottopolitics in the Democratic Republic of Congo. It adopts an innovative approach known as linguistic ecology, which analyzes the dynamic relationships between languages and society. The author emphasizes that the vitality and survival of a language depend on its societal management and the involvement of various social groups. The text calls for equitable government intervention to regulate the use and status of languages—whether major, medium, or minority—in order to ensure social cohesion and prevent community unrest. The ultimate goal is to make this approach operational by identifying an endangered language and proposing concrete solutions for its preservation. Keywords : Écologie linguistique, Glottopolitique, Équité linguistique, langues en extinction
The analysis presented in this study demonstrates that the major contribution of the sui generis system is to legitimize the collective property of local communities in the DRC. Unlike classical intellectual property law, which seeks to highlight a single author, the approach used in this research recognizes that knowledge belongs to the community. It also serves to protect the integrity of the community against individual misappropriation. This sui generis mechanism for the protection of traditional knowledge in the Democratic Republic of Congo offers several fundamental perspectives, encompassing both a purely defensive vision and a proactive vision of cultural and biological heritage. Keyword : misappropriation, sui generis mechanism, knowledge, fundamental perspectives,
The study of Mba sociocultural spaces was well-structured, and nothing could be done without taking into account the norms established by the Mba or Bamanga society. We have identified the following structures: a. Social structures: - Clan structures: "ATIKÁ" with a common ancestor "MBAPÁ" - Road structures: "ZAKWA" caravan routes, "KOKWA NENA" agricultural desert routes, and main roads; - Medical structures: "KWAGO", KWIBIDJWA (traditional treatment), Bengamisa referral hospital, and 18 health centers - School structures: Primary schools (35), secondary schools (25), Bengamisa Higher Agricultural Institute; - Agrarian structures: Family share "BIKOKOLOUMA", each clan has its portion of land to cultivate, and even its offspring have the right to a portion of land to work b. Mba cultural structures: - Structures of magical-religious beliefs: KOMAME (witchcraft), OBOKAGBOKA = animal that transforms BWOU = belief in domination WEE = Weakening or weakening of a man by a woman ABOMBE or FONOLI Mutual cultural associations Structures of folk dances. The Mba social organization comprises the social system and the cultural system, which are both distinct and connected through institutionalization. This translates general cultural elements: values, symbols into activity norms that are inscribed in the concrete roles experienced in social action. The Mba sociocultural spaces are formed into structures based on a communal spirit, coherent, homogeneous, and stable in terms of group solidarity. The Mba live in perfect harmony with their neighbors despite some land conflicts, which end up being resolved through respect for agreements and traditional alliances via communication networks. Keywords: Spaces, social, culture, structure.
