The agricultural industry is crucial to the development of the national economy. Inadequate agricultural equipment maintenance could result to a huge economic impact, especially during the harvest period. Thus, this study highlighted on the importance of condition monitoring of agricultural machinery/equipment for enhanced agricultural productions. The study established that adequate condition monitoring of agricultural machineries provides reliability data that will help in the implementation of the integrity of maintenance strategies. Additionally, adequate health monitoring of the advanced machineries will help in improving the efficiency of the machines as well as improving the overall agricultural productivity. This study provides great insight to farmers on the way to monitor and maintain the health of their agricultural machineries.

Condition monitoring is an essential technique which is usually deployed to monitor the health parameters and conditions of a boiler plant in such a way that variations or significant changes can like failure can be identified and proffer adequate solutions to it. It is an important aspect of condition-based maintenance which is used in maintaining an equipment according to its conditions. Thus, this study focused on the fundamental principles of condition monitoring which involve the identification and selection of a physical measurement that will show the deterioration stage and the importance of taking the readings at intervals. More so, the study established that monitoring and measurement should focus more at critical components that have high frequency of failure. Thus, condition-based maintenance of boilers will help in improving the ,availability of the boiler.

This review investigates the impact of maintenance methods on machine reliability, focusing on their relationship with overall performance, durability, and availability. It emphasizes the importance of proactive maintenance, such as preventive maintenance, to identify and treat potential issues before they become significant failures. The review also examines the effectiveness of various maintenance procedures in enhancing machine reliability, examining the cost-benefit ratio of maintenance programs and the potential savings gained through improved reliability. The review highlights the role of maintenance methods in limiting risks and enhancing performance, emphasizing the importance of proper maintenance practices in ensuring smooth operations and reducing downtime.

INTRODUCTION: Few reports from Nigeria have examined the quality of life (QOL) of people living with HIV/AIDS (PLWHA) despite the fact that Nigeria has the second largest number of PLWHA in the world. This study evaluated the QOL of Nigerians living with HIV/AIDS using the World Health Organization Quality of Life Questionnaire for HIV-Brief Version (WHOQOL-BREF) instrument and assessed the impact of demographic, laboratory and disease-related variables on QOL. METHODS: This cross-sectional study involved 491 consecutive PLWHA aged e" 18 years attending the dedicated clinic to PLWHA in South-west Nigeria. RESULTS: The lowest mean QOL scores were recorded in the environment and social domains. Participants aged e" 40 years had better QOL in the environment (p = 0.039) and spirituality (p = 0.033) domains and those in relationships had better QOL in the social relationship domain (p = 0.002). Subjects with no or primary education and those who rated their health status as good gave significantly higher ratings in all QOL domains. Participants with AIDS had significant lower QOL in the level of independence domain (p = 0.018) and those with CD4 count e" 350 cells /mm3 had better QOL scores in the physical, psychological and level of independence domains. Subjects without tuberculosis co-infection and those on antiretroviral therapy (ART) reported significantly better QOL in the physical, psychological, level of independence and spirituality domains. CONCLUSION: Marital relationship, absence of tuberculosis, CD4 count e" 350 cells /mm3 and use of ART positively impacted QOL of our patients.
