This study developed a machine learning-based failure predictive application software to improve the operational efficiency and reliability of turbo-compressors in gas injection plants. The Gas injection plant produced below maximum capacity due to failure problems of the Turbo-compressors, these affected the targeted oil production negatively. The unavailability and unreliable gas plant led to revenue losses. The failure analysis revealed that equipment and material issues, human factors, external factors, and management-related issues contributed to equipment failures. Machine learning techniques, specifically Logistic Regression, Support Vector Machines (SVM), Boosted Trees, and Artificial Neural Networks (ANN), were employed to develop the failure predictive application software. The results showed that the Efficient Linear SVM model achieved a true positive rate of 99.5% for detecting failures and 99.9% classification precision for non-failure events. The Boosted Trees model achieved a true positive rate (TPR) of 99.5% for detecting failures, although it demonstrated a 0.5% false negative rate, highlighting the need for further optimization and integration with ensemble techniques to minimize operational risks. The SVM model further showcased 99.9% classification precision for non-failure events and a minimal false negative occurrence. The nearly perfect R-values across training, validation, and test datasets, coupled with minimal MSE values at the optimal number of epochs displayed by the ANN model further confirmed that the model can generalize effectively to unseen data. The outcomes of this research yielded a highly effective, computationally efficient machine learning-based application software capable of reliably predicting turbo-compressor failures. The study concluded that the developed application software is a powerful tool for predicting failures in gas injection plants, supporting decision-making processes, and enhancing operational safety. Recommendations for future works included refining existing models, exploring additional feature engineering techniques, and evaluating the robustness of the models under varying operational conditions.

The objectives of this cross-sectional study were: To conduct a reflective analysis on the issues surrounding the pedagogical supervision of continuing education trainees; To assess the degree of satisfaction among these trainees regarding the quality of guidance provided by their pedagogical supervisors. The trainees’ perceptions of pedagogical supervision were collected through a questionnaire designed specifically for this study. It was developed based on recommendations from the literature and underwent both internal and external validation of its content. The surveyed trainees expressed their opinions in response to the items administered. In total, twenty-eight (28) Physical Education and Sports teachers all continuing education students at the Higher Institute of Physical Education and Sports undertaking internships at three (3) colleges in Brazzaville (CEG 28 Novembre in Moukoundo, CEG Bayonne in Nkombo, and CEG Ibaliko in Massengo), constituted our research field. These were the institutions where the students were assigned for practical training. The results of our study show that 87.50% of the continuing education students surveyed believe that discussions with supervisors are very important. This positive perception is explained by the fact that nearly all the students 95% reported enjoying freedom of expression during these discussions, which fostered a sense of trust. In this regard, our study is of great utility to education policymakers, who may use its findings to take appropriate measures aimed at improving teaching and learning in schools. Acknowledging that this study only scratches the surface of the broader issue of pedagogical supervision for student-teachers, we believe it would be worthwhile to pursue further research exploring this same issue from different perspectives in order to build a more complete picture of the current situation.

Penile strangulation is a rare event that requires emergency treatment. Metal rings are most commonly used on the penis for autoerotic or aggressive purposes or to enhance sexual performance. We report a case of a 19-year-old male patient undergoing psychiatric treatment at the Dalal Xél health center in Fatick, who was admitted to the emergency department of Kaffrine Regional Hospital (in Senegal), for penile strangulation by a metal ring. The ring had been placed at the root of the penis three days earlier. The patient had no urinary disorders. Treatment consisted of removing the ring and providing psychiatric care. However, to prevent urinary and sexual complications, treatment must be provided early. Through this observation and data from the literature, the authors report the subtlety of the management of this pathological situation, highlighting the psychotic context which favors this type of self-aggressive behavior.

Middle Eastern cinema has received increasing attention in academia for its cultural and gendered narratives, but family systems' emotional architecture in such films has received little attention. Filling this gap in the literature, this research applies Murray Bowen’s Family Systems Theory to examine intergenerational emotional processes in Wadjda (2012), the first feature film by a Saudi woman. In this study, I utilized qualitative, doctrinal methodology and applied deductive scene-based codes from Bowen’s eight constructs, which focused primarily on emotional differentiation, triangulation, projection, and societal emotional process. Findings suggest Wadjda’s resistance extends beyond a symbolic or superficial act of defiance, whereby she is able navigate maternal fusion, paternal absence, and societal constraints through her emotional processes associated with features of agency, autonomy and relational clarity. In social and familial systems, her portrait of agency exemplified systemically embedded agency that serves as a form of supported emotion-regulated defiance. By drawing on cultural and feminist film analysis with Bowen’s clinical theory, I challenged traditional perceptions of social family systems, providing a different lens to view emotionally supportive family systems as active sites of gendered negotiation. The contribution from this study extends family systems theory beyond a therapeutic sense, offering another approach to understand how emotionally enabled dynamics provide resistance in patriarchal societies. Specifically, it became apparent that depictions of agency in patriarchal cultures through an emotional systems framework may provide a deeper analysis of resistance than only through a symbolic critique.

Despite the government's effort to implement a Competency-Based Curriculum in technical and vocational training institutions, institutional factors remain a significant obstacle in this process. These challenges collectively impede the successful execution of CBET programs in the region and warrant a closer examination of the influence of institutional factors on its implementation. This study adopted a descriptive survey design employing a mixed methods approach. The sample included 363 respondents, comprising 335 trainees, 23 trainers, 3 technicians, and 2 principals. The findings indicated that while a majority of respondents acknowledged the availability of sufficient teaching and learning resources for CBET (56.4%), there was a widespread perception of a lack of clear implementation guidelines (74.6%). Moreover, institutions were found to have insufficient policies for CBET (71.9%), and insufficient learning infrastructure (57.8%). Notably, most institutions were not actively engaged in monitoring and evaluating the implementation of CBET (70.4%). In this case, the study established that there was positive correlation between institutional factors and implementation of CBET in Meru County (r = .286; p = .000). Consequently, the study recommended that institutions should prioritize the allocation of adequate resources, including teaching and learning materials, workshops, and infrastructure, to support effective CBET implementation. Also, institutions should emphasize the development and communication of clear guidelines and policies to all stakeholders. Additionally, the study recommended the establishment of regular monitoring and evaluation mechanisms—conducted at least biannually—to track CBET implementation progress and identify specific areas for improvement. It further advised fostering structured partnerships with government agencies and industry stakeholders through formal agreements and joint initiatives, reviewed annually, to strengthen institutional support for CBET.

The neuropsychiatric conditions; depression and anxiety develop from oxidative stress together with neuroinflammation. The research evaluates if lutein ameliorates anxiety and depression symptoms in rats exposed to scopolamine. 36 male Wistar rats (105g - 153g) were distributed randomly into six distinct groups. Group 1: Negative Control, Group 2: Scopolamine only treated group, Group 3: Scopolamine + Lutein (20mg/kg), Group 4: Scopolamine + Lutein (40mg/kg), Group 5: Scopolamine + Lutein (60mg/kg), Group 6: Scopolamine + Imipramine (standard drug - 10mg/kg). Scopolamine was administered intraperitoneally and lutein orally. Statistical analysis was conducted through one way ANOVA with Post hoc Fischer’s LSD. The experiment used P<0.05 for multiple comparison significance detection. Superoxide Dismutase (SOD), and Glutathione (GSH) levels in Group 2 decreased substantially (p < 0.01 and p < 0.0001) when compared to control, Groups 4, 5, 6 which improved the SOD and GSH levels toward normal levels. Catalase decreased dramatically (p < 0.0001) in Group 2 but treatment in Groups 4 and 5 elevated significantly (p < 0.01). These outcomes establish that Lutein protects against scopolamine induced oxidative stress, behavioral deficits and neurotoxicity. The research established that lutein treatment produced positive results for reversing both oxidative stress conditions and neurotoxicity effects and behavioral deficits provoked by scopolamine. Scopolamine caused a decrease in antioxidant enzymes levels which Lutein treatment at middle and high doses (40 and 60 mg/kg) successfully countered by restoring biomarkers, boosting neurotrophic signals for better behavioral results.

Tennis is a physically demanding sport that requires quick movements, rapid changes of direction, and powerful strokes. Core stabilization is essential for maintaining good posture, generating force, and reducing injury risk. This interventional study aimed to investigate the effectiveness of core stabilization exercises on lumbopelvic rhythm, speed, and agility in adolescent tennis players. Thus, the aim of this study was to assess the impact of core stabilization exercises on lumbopelvic rhythm, speed, and agility in adolescent tennis players. 45 participants (Age 15.66 year’s ± 1.14 years) of both genders: 31 male (height 154.23± 6.67CM weight 48.30±6.36kg) (B.M.I 20.04±1.39) and 14 female (height 15.79±1.05 CM weight 49.29±5.41Kg) (B.M.I 20.54±1.67) with 6 months to 2 years of tennis experience were included in this interventional study. Participant’s pre and post data were collected for lumbopelvic rhythm (Schobers test), speed (30 m sprint test) and agility (T- test). The study results showed significant improvements in lumbopelvic rhythm, speed, and agility among the participants following the core stabilization exercise program. These training programs can enhance athletic performance and reduce injury risk.

Detergents are amphiphilic compounds with crucial roles in the extraction, purification and stabilization of integral membrane proteins and in experimental studies of their structure and function. One technique that is highly dependent on detergents for solubilization of membrane proteins is solution-state nuclear magnetic resonance (NMR) spectroscopy, where detergent micelles often serve as the best membrane mimetic for achieving particle sizes that tumble fast enough to produce high-resolution/high-sensitivity spectra. The best quality NMR spectra use detergents with partial or complete deuteration, which eliminate interfering proton signals from the detergent itself and eliminate potential proton relaxation pathways and strong dipole-dipole interactions that contribute line broadening effects. Another technique for which deuterated detergents have been crucial to obtain structural information about membrane proteins in solution is small-angle neutron scattering (SANS). Use of a deuterated detergent exploits the intrinsic neutron scattering length difference between hydrogen and deuterium, such that detergent is matched-out in D2O and only signal from the membrane protein remains visible in the scattering profile, simplifying data analysis. We provide an updated review on the properties, chemical synthesis and applications of detergents that are commercially available and/or that have been synthesized with partial or complete deuteration, and that have been used in NMR or SANS studies on membrane proteins. Specifically, the detergents are sodium dodecyl sulphate (SDS), lauryldimethylamine-oxide (LDAO), n-octyl-β-D-glucoside (β-OG), n-dodecyl-β-D-maltoside (DDM) and fos-cholines including dodecylphosphocholine (DPC). We also consider effects of deuteration, detergent screening and guidelines for detergent selection.

Introduction: Cardiovascular risk factors (RDFs) are on the rise in developing countries, particularly in sub-Saharan Africa. Dyslipidemia, which is often found, can be linked to changes in eating habits. Material and Methods: We performed a prospective descriptive and analytical study to evaluate cardiovascular RDFs in patients who presented with dyslipidemia in general practice. Results: In the 58 patients included, the mean age was 54.15 years ± 13.85 years. The female sex was predominant with a sex ratio (M/F) of 0.41. High blood pressure was found in 68.96% of cases, diabetes mellitus in 32.75% of cases. The mean body mass index (BMI) was 27.65 kg/m2 with extremes of 17.57 and 49.99 kg/m2. The mean waist circumference was 95.94 cm with extremes of 62 and 170 cm. According to NCEP ATP III, 28 women had a waist circumference ≥ 88 cm or 48.27% and 3 men had a waist circumference ≥ 102 cm or 5.17%. The lipid abnormalities were distributed as follows: LDL cholesterol > 1.6 g/l (93.10%), HDL-cholesterol < 0.4 g/l (24.13%), total cholesterol > 2 g/l (96.55%), triglycerides > 1.5 g/l (32.14%). The most common electrical abnormalities on ECG were subepicardial ischemia (8.62%), right bundle branch block (5.17%) and left ventricular hypertrophy (5.17%). The overall cardiovascular risk was elevated in 30.62% of patients. Metabolic syndrome was reported in 82.75% of cases. Conclusion: Dyslipidemia may be the bedrock of latent elevated cardiovascular risk, especially if it is associated with other factors. Prevention involves screening and good awareness by the general practitioner.

Wearable cardiovascular devices have emerged as essential tools for continuous heart rate monitoring. Especially for the early detection and management of heart related conditions. This article explores the advancements and functionalities of four categories of the wearable heart monitoring products like, smart patches, in – ear heart monitoring devices, smartwatches and smart rings. The smart patches offer clinical grade heart rhythm data with mobility, allowing real- time analysis without hospital equipment. In- ear monitors, utilizing photoplethysmography (PPG) sensors, provide accurate readings from the ear canal due to its rich blood supply. Smartwatches combine multi sensor capabilities, including heart rate, blood oxygen levels, and ECG, with smartphone integration for user friendly health tracking. Smart rings, the most discreet among them, prioritize minimalism while offering essential metrics like heart rate variability (HRV), sleep, and activity data. These technologies collectively push the boundaries of personalized healthcare, providing accessible, real time cardiovascular monitoring.

A series of novel substituted 2-((3-chloro-2-methylphenyl) ((1-phenyl-1H-1,2,3-triazol-4-yl)methyl)amino) benzoic acid (5a-l) derivatives were synthesized using a multi-step synthetic route involving the click chemistry approach. The structures of the synthesized compounds were confirmed using various spectroscopic techniques, including NMR, IR, Mass and elemental analysis. The antibacterial and antifungal activities of the synthesized compounds were evaluated against a panel of bacterial strains (including B. Subtilis, B. Sphaericus, and S. Aureus, P. Aeruginosa, K. Aerogenes and C. violaceum) and fungal species (such as C. albicans, A. Fumigatus, T. Rubrum and T. mentagrophytes). The results revealed significant inhibitory effects, with some derivatives showing superior activity compared to standard drugs. Additionally, the cytotoxicity of these compounds was assessed against human cancer cell lines (MCF-7, PC-3, and HeLa) using MTT assays. Several derivatives exhibited potent cytotoxic effects, indicating their potential as anticancer agents. Molecular docking studies of newly synthesized derivatives 5a-l, along with Doxorubicin and Tamoxifen, against enoyl reductase (PDB ID: 1QSG) indicate potential inhibitors for lipid biosynthesis in cancer therapy.

Fifteen coal samples were collected from Dangote, Zouma. and Omelewu coal sites, Kogi, State. Five samples from each site were subjected to laboratory tests which include proximate analysis, ultimate analysis, calorific value and total Sulphur content determination to determine their suitability for power generation. ASTM D3173, ASTM D5142, ASTM D3175, and ASTM D5865 standards were used respectively. Tests were carried out at FUTA laboratories and Sheda Science and Technology laboratory, Abuja, Nigeria. Dangote coal is a sub-bituminous B, low Sulphur and medium ash coal; Zouma sub-bituminous C, low Sulphur, medium ash coal, while Omelewu coal is a sub-bituminous C, low Sulphur, low ash coal. The coal samples analyzed are suitable for power generation (Heating value: 8,300 - 9,500 Btu/lb; Moisture content: 16.52% - 17.49%; Low Sulphur content <1.0); low to medium Ash contents 8.0-15.0%) and is in agreement with requirements published by coal-fired power plant operators. Gross calorific values, inherent moisture and contents of Zouma sub-bituminous coal make it more largely suitable for pulverized coal combustion when compared with the coal fuel used for the Genessee Phase 3 power station in Canada.

This narrative review comprehensively evaluates the clinical applications and effectiveness of oral irrigators (water flossers) compared to traditional interdental aids in the management of periodontal and peri-implant diseases. Drawing from an extensive literature search across databases including PubMed, Embase, MEDLINE, and Google Scholar (1971–2025), the review covers historical evolution, current usage patterns, device classification, and future technological advancements in water flossing. Oral irrigators, which utilize pulsating and pressurized water streams, have demonstrated efficacy in plaque removal, reduction of gingival inflammation, and improved access to subgingival and interproximal areas—particularly beneficial for patients with implants, orthodontic appliances, or compromised manual dexterity. Clinical evidence indicates that water flossers are often superior or at least equivalent to dental floss and interdental brushes in reducing bleeding on probing, plaque indices, and inflammatory markers. Furthermore, their synergistic use with antimicrobial agents such as chlorhexidine enhances their therapeutic impact. While water flossers show promise in improving patient compliance and oral hygiene outcomes, certain limitations—such as the risk of transient bacteremia and microbial colonization—warrant further investigation. Innovations like app-controlled devices, biofeedback mechanisms, and AI-driven water flow adjustments represent the future of personalized oral hygiene. Overall, water flossers emerge as effective, patient-friendly tools with broad utility in modern dental care. Continued research and innovation will further solidify their role in promoting periodontal and peri-implant health.
