In recent times, the entire world has been in consistent search of cleaner and safer ways of generating and producing energy. Due to continuous industrialization in different parts of the world, there has been a huge deterioration in the natural state of the environment. This is reflective in different areas and the most prominent has to be Climate change. This paper therefore focuses on the exploitation of the abundant solar energy from the sun to drive a lawn mower. The designed solar powered lawn mower comprises of electric motor, a charge controller, battery (12V), Solar Panel (30W), rotational blade and a control switch. The entire operation frame work is achieved using the electric motor which is able to provide the necessary torque needed for the rotation of the blade which is mounted to the shaft of the motor. The solar powered lawn mower is operated by a switch on the board which closes the circuit and allows current flow to the motor and ultimately, causing the actuation of the blade. Under a very sunny condition battery charges and operates simultaneously, taking a longer time to discharge. Finally, the performance evaluation of the battery was carried out with the machine and it was found to have a theoretical efficiency of 85%.

This study investigates the prevalence and impact of child abuse and neglect in Nkpor-uno, located in the Idemili North Local Government Area of Anambra State, highlighting a critical issue with profound lifelong implications. With a focus on understanding the scope of child abuse and neglect within this community, the research adopts a methodological framework guided by the principles of social learning theory. The study's objectives were pursued through the analysis of data collected from a purposively sampled group of 100 parents and caregivers out of a targeted population of 1,000 residents. Utilizing a specially designed structured questionnaire, the study employed quantitative methods, specifically frequency counts, means, and standard deviations, to analyze the collected data. The findings of the research are alarming, indicating a 91% prevalence rate of child abuse and neglect in Nkpor-uno, which underscores the urgent need for comprehensive strategies to address this crisis. Based on these results, the study proposes a multifaceted approach to combat child abuse and neglect. It calls for a collaborative effort involving parents, caregivers, educational administrators, healthcare professionals, non-governmental organizations, and governmental bodies. The aim is to foster a supportive environment that not only prevents child abuse and neglect but also ensures the rehabilitation and well-being of affected children. This study contributes to the broader discourse on child welfare and serves as a call to action for all stakeholders to prioritize and address the issue of child abuse and neglect in Nkpor-uno and beyond.
