The main objective of this research is to investigate some properties of fresh and hardened concrete using glass powder as a partial replacement of cement at percentages of 15%, 25%, and 35% by weight, and to determine the optimum replacement ratio. Four concrete mixes were prepared with replacement levels of 0% (control mix), 15%, 25%, and 35% of cement by glass powder. Six cube specimens were cast for each mix. Tests were conducted on fresh concrete (slump test) and hardened concrete (compressive strength test) at curing ages of 7 and 28 days. The results showed that the workability of concrete increased with increasing percentages of cement replacement by glass powder; however, the slump values remained lower than that of the control mix. Moreover, the results indicated that replacing 15% of cement with glass powder increased the compressive strength by 7% compared to the control mix (0%). Based on the results obtained, the optimum percentage for partial replacement of cement with glass powder is 15%.

Glomus jugulare tumors are rare, highly vascular paragangliomas of the skull base that pose significant surgical challenges due to their proximity to critical neurovascular structures and their propensity for extensive local invasion. In low- and middle-income countries such as Nigeria, limitations in access to advanced imaging, preoperative embolization, intraoperative neuromonitoring, and blood products further complicate management. The objective is to describe the surgical technique, perioperative management, and outcomes of patients with glomus jugulare tumors managed in a Nigerian hospital. This was a prospective case series of patients with radiologically confirmed glomus jugulare tumors managed surgically from January 2024 to December 2025. Preoperative evaluation included cranial nerve assessment and cross-sectional imaging. Surgical approaches, extent of resection, estimated blood loss, perioperative complications, and functional outcomes were analyzed. Seven patients were included, with a mean age of 45.7 years. Hearing loss and lower cranial nerve dysfunction were the most frequent presenting symptoms. Gross total resection was achieved in 5 patients (71.4%). The mean estimated blood loss was 253 ml. One patient (14.3%) developed new or worsened postoperative lower cranial nerve deficits, which improved during follow-up. No perioperative mortality occurred. Adjuvant radiotherapy was recommended for subtotal resections but could not be administered due to limited availability. Despite significant resource constraints, surgical management of glomus jugulare tumors in Nigeria is feasible with acceptable oncological and functional outcomes. Early diagnosis, meticulous microsurgical technique, and a multidisciplinary collaboration remain critical for optimizing patient outcomes in resource-limited settings.

The study Investigates empirically the Impact of technological development on deposit money banks’ performance in Nigeria using annual lime series covering a period of 13 years, which is between 2009 Ql and 2021 Q4. To accomplish this objective, descriptive statistics, the unit root test, and Toda- Yamamoto modelling techniques were adopted for the analysis. The study shows that the number of points of sale does not affect deposit money banks' performance; and the number of mobile payments does not affect deposit money banks’ performance in Nigeria, but the number of automated teller machines enhances deposit money banks Performance. The study therefore concludes that technological development enhanced deposit money banks’ performance in Nigeria within the period of study. The study recommends that efforts be made to improve the efficiency of ATM service delivery in the country. There is a need to always fund the machines to ease transactions and prevent the risk of customers carrying cash over long distances to banks.

The purpose of this investigation was to examine the effects of Orangetheory fitness training, yogic practices, and their combined application on psychological stress among obese school students. Sixty obese students aged between 12 and 14 years from schools in and around Thoothukudi, Tamil Nadu, were selected as participants. The subjects were randomly assigned into four groups consisting of fifteen students each. Group I participated in Orangetheory fitness training, Group II performed yogic practices, Group III underwent a combined programme of Orangetheory training and yoga, while Group IV served as the control group without any specific intervention. Psychological stress was considered the dependent variable and was measured using the standardized Every and Grinodo Psychological Stress Scale. The experimental programmes were conducted for twelve weeks with five sessions per week. Data were collected before the commencement of the training and immediately after the completion of the intervention period. The collected data were analysed using the dependent t-test and Analysis of Covariance (ANCOVA). Whenever the adjusted post-test F-ratio was found significant, Scheffe’s post-hoc test was applied to determine the paired mean differences. The level of significance was fixed at 0.05. The findings revealed significant differences among the experimental and control groups, and the combined training programme produced greater stress reduction compared with the individual training methods.

Lichens, a symbiotic partnership between fungi and algae, possess a remarkable array of biological properties. This study explored the antibacterial and antioxidant potential of extracts from two lichen species: Bulbothrix isidiza and Parmotrema reticulatum. The disc diffusion method revealed promising antibacterial activity in both lichen extracts against Gram-positive and Gram-negative bacteria. Notably, the ethyl acetate extract of B. isidiza and the ethanol extract of P. reticulatum exhibited the strongest inhibitory effects. The DPPH free radical scavenging assay confirmed antioxidant activity in both lichen extracts, with scavenging activity increasing with extract concentration. These findings suggest the potential for these lichens as sources of natural antimicrobials and antioxidants. Further research is necessary to identify the bioactive compounds responsible for these activities and assess their potential therapeutic applications.

While the mitigation of climate change is typically framed as a problem globally, the literary genre of climate fiction (cli-fi) plays an indispensable role in shaping the cultural and psychological conditions necessary for collective action. Climate fiction addresses the issue by transforming abstract statistics and distant future projections into tangible, emotionally resonant human experiences. First, cli-fi serves as a "prosthetic imagination," allowing readers to inhabit the lived realities of a warming planet thereby breaking through the psychological barriers of temporal and spatial distance that often paralyse action. By providing concrete sensory details and character-driven plots, these narratives make the "hyperobject" of climate change comprehensible and personally relevant. Thus, the paper is an attempt to examine how climate fiction functions as a repository for future memory and a workshop for social resilience. Unlike purely apocalyptic narratives that can induce fatalistic despair, the most effective works of climate fiction model adaptive strategies, reimagine community structures and explore the ethical dilemmas of mitigation and justice. They offer speculative spaces where readers can confront the emotional weight of loss while simultaneously envisioning pathways toward survivable and even thriving futures. This process of pre-traumatic growth and narrative forecasting is crucial for building the psychological stamina required for long-term civic engagement. Cli-fi shape the perceptual frameworks through which society interprets the world with positive impacts. In a culture saturated with misinformation and short-term thinking, climate fiction provides a counter-narrative that centres long-term responsibility and interconnectedness. To conclude, mitigating climate change requires not only technological innovation but also a transformation of the human imagination. By bridging the divide between knowing and feeling, climate fiction cultivates the moral urgency and collective will needed to translate awareness into action, positioning narrative as an essential, though often overlooked, tool in the global effort to stabilize the planet’s climate.

Congenital Hypothyroidism is a rare but serious malformative pathology, subject to congenital screening in several countries around the world. its impact once omitted is serious and irreversible. The form with agenesis of the thyroid gland called athyreosis can be associated with several malformations, cardiac, renal or skeletal. Patients living with athyreosis most often have symptoms of chronic hypothyroidism, which can be attributed either to a FT3/F4 ratio that is too low or a defect in the peripheral deiodation of T4 to T3. We report the case of a young girl with athyreosis who maintains a refractory hypothyroidism syndrome.
