Abstract
Leadership behaviour is shaped not only by organisational structures and professional training but also by personal and relational experiences across the life course. This paper examines the role of sexual experiences and sexual relationship transitions in influencing leadership behaviour and competencies. Drawing on leadership theory, attachment theory, and life-course perspectives, the study conceptualises sexual experience broadly to include intimacy, attachment, power negotiation, and relational change. A narrative literature review was conducted using peer-reviewed sources from psychology, leadership studies, and social science, focusing on emotional regulation, identity formation, ethical reasoning, and interpersonal competence. The findings indicate that healthy, consensual, and emotionally supportive sexual relationships can enhance leadership-relevant competencies such as emotional intelligence, empathy, confidence, and transformational leadership behaviour. Conversely, relational instability or unresolved relational trauma may temporarily constrain leadership effectiveness, though such experiences can also foster long-term growth and adaptive leadership capacity. Relationship transitions, including partnership formation and dissolution, are shown to influence leadership behaviour through their impact on self-concept, resilience, and decision-making processes. The analysis challenges compartmentalised models of leadership that separate professional competence from personal relational development. Instead, it advances a holistic framework recognising sexual and relational experiences as developmental influences on leadership behaviour. Implications are discussed for leadership development, organisational support, and future research, particularly the need for longitudinal and intersectional approaches that integrate personal life experiences into leadership theory and practice.

Abstract
This research presents an economic analysis of a 30 kVA Solar Photovoltaic (PV) water Irrigation pumping (5 kW) system tailored for sustainable agricultural irrigation. The proposed system comprises 60 high-efficiency solar panels rated at 400 W each, a modular inverter configuration for power conversion, and supporting infrastructure, including mounting structures, piping, and control systems. The system meets a daily energy demand of 240 kWh, and 24 kW of total watts modules with operational parameters including 10 hours of daily use and 300 days of annual operation. The economic analysis evaluates capital and operational expenditures, highlighting the long-term cost advantages of the solar PV system over diesel-powered alternatives. The capital cost of the solar system is ₦13,900,000, including ₦6,600,000 for panels, ₦3,000,000 for a modular inverter setup, and other associated infrastructure costs. The Levelized Cost of Energy (LCOE ₦16.57/kWh) and Net Present Value (NPV ₦158,000,000) analyses underscore the system’s economic feasibility, with a payback period of approximately 7.2 years. Environmental impact analysis reveals significant carbon savings, with the PV system producing only 48,000 kg of CO₂ emissions over its lifetime compared to 201,000 kg from a diesel system, reducing the environmental burden by over 76%. This study demonstrates that the solar PV irrigation system offers a sustainable solution by reducing energy costs, mitigating carbon emissions, and enhancing agricultural productivity. Recommendations focus on quality installation, scheduled maintenance, and provisions for scalability to adapt to future energy demands, ensuring the system’s reliability and alignment with sustainability goals over its 25-year lifespan

Abstract
This study evaluated the nutritional quality of fermented BG and local rice (FARO-8 short grain) flours and the effect on the mean growth weight of albino weanling rats. Bambara groundnut (BG) is a highly nutritious crop that plays an important role in people’s diet but contains antinutrients. The BG seeds used for the study were fermented at different periods to produce flours. Blends of fermented Bambara groundnut and local rice flours were formulated and the nutrient content and the biological value were determined. A total of seven diets were formulated. The ratios of the blends of 48hrs fermented Bambara groundnut to Uzuakoli rice (FARO-8 short grain) were: 80:20 (BFE1:R), 70:30 (BFE2:R), 60:40 (BFE3:R). Other three diets formulated using Bambara groundnut flours at 24hr, 48hr and 72hr fermentation periods alone were in the ratio of 100:0 respectively (BTF:0, BFE:0 and BST:0). Then, 0-hr Bambara groundnut blend in the ratio of 100:0 served as the control (BZE*). Seven groups of albino rats were fed the blends respectively and the mean growth were measured weekly using electronic weighing balance during the study period. This study was carried out for 35 days. Result of the nutrient determination showed that the moisture content of the diet blend ranged from 9.27 to 10.30%. There were significant differences (P<0.05) in the protein content of the blends and it ranged from 18.48 to 22.81%. The fat content also varied and ranged from 5.76 to 8.30%. The ash values ranged from 3.26-3.94%. The fibre content also varied. All the composites had high carbohydrate values that ranged from 53.65 to 58.98%. There were significant differences in the mineral values (P<0.05). There were also significant differences in their vitamin levels (P>0.05). The antinutrients showed high level of significant differences (P<0.05). The mean growth values (119.94g) of the rats fed diet BFE:0 were the highest. Results obtained showed that fermentation had a significant effect on the protein quality of the blends and on the mean growth weight of the albino rats. Fermentation of legumes is necessary in improving the nutritional quality.
