This paper analyses the quality maintenance in Bendel Feeds and Mills, Ewu, Edo State, with a view of designing a robust maintenance process and schedule to enhance production equipment in the company. The specific objectives were to determine the failure rate in the company production equipment, establish the appropriate maintenance process needed to reduce failure rate, investigate whether the current material handling methods and practices permit high maintenance turnover and to proffer useful suggestions and ideas on how to effectively maintain production equipment in the company. Data obtained were used to analyse the materials handling equipment failure rate, MTTR, MTBF, availability, failure mode and work station. The results showed that the failure rate is more in bucket elevator equipment than other materials handling equipment. It was observed that the plant organisational structure is area controlled instead of centre controlled organisation, which is one of the problems of the plant maintenance policy adopted by the company. Maintenance of materials handling equipment of the plant can be better achieved through modified planned preventive maintenance, condition base maintenance (predictive) and equipment inspection. This analysis will be of tremendous help to practicing maintenance engineering.

Currently a fundamental gap exists on how persistent organic pollutants affect humans especially those who consume high levels of seafood from contaminated coastal waters. There is an urgent need to better understand effects of these contaminants on human health in coastal communities. Elevated contaminant levels in coastal seafood will give rise to increased contaminant burdens in humans who consume coastal seafood and given the toxicity of these contaminants increase risk for immune system disorders. In this paper we describe how we assessed the effects of contaminant exposures using high-throughput RNA sequencing (RNA-seq) in peripheral blood mononuclear cells from two species, dolphins and humans. This paper presents an integrated systems biology approach to understand the adverse effects of one of these CECs PFAS on both species.

This paper analyses the economics of material management in the 7up Bottling Company, Benin for the duration (2011 – 2015) with a view of designing a process inventory. The specific objectives were to determine the level of efficiency and product improvement in material management, investigate whether the material management practice permit high stock turnover validation and to proffer useful suggestions on how to effectively manage the company materials. The variance analysis and Economic Order Quantity (EOQ) model were used to analyse the data collected. The results showed that the company spent a total of 118.8 million naira for production process and made a total sale of 395.84 million naira. This implies that the company optimises production by adopting the EOQ model into their production process and management. Based on these findings, the study recommends that optimal quantity and timing of material ordering in production process is a key to profit maximisation.

This paper presents an excerpt of a more comprehensive survey of smart grid systems on electric power distribution networks and its impact on reliability. The survey was carried out as part of the feasibility study in Nigeria to determine its enhance-ability on the smartness of a conventional (traditional) distribution network. A smart grid is not a single technology but multiplex technologies in which the combination of different areas of engineering, communication and energy management systems are done. Consequently, a comprehensive review of various approaches and their impact on reliability of the network is presented. Furthermore, this paper introduces the smart grid technology and its features, reliability impacts and emerging issues and challenges that arise from the smart grid system applications. The benefit of this comprehensive survey is to provide a reference point for educational advancement on the recently published articles in the areas of smart grid systems on electric power distribution network as well as to stimulate further research interest.

The process industry has always been faced with the challenging tasks of determining the overall unavailability of safety instrumented systems (SISs). The unavailability of the safety instrumented system is quantified by considering the average probability of failure on demand. To mitigate these challenges, the IEC 61508 has established analytical formulas for estimating the average probability of failure on demand for K-out-of-N (KooN) architectures. However, these formulas are limited to the system with identical components and this limitation has not been addressed in many researches. Hence, this paper proposes an unavailability model based on Markov Model for different redundant system architectures with non-identical components and generalised formulas are established for non-identical k-out-of-n and n-out-of-n configurations. Furthermore, the proposed model incorporates undetected failure rate and evaluates its impact on the unavailability quantification of SIS. The accuracy of the proposed model is verified with the existing unavailability methods and it is shown that the proposed approach provides a sufficiently robust result for all system architectures.
过程工业一直面临着确定安全仪表系统(SISs)整体不可用性的挑战性任务。通过考虑按需失效的平均概率来量化安全仪表系统的不可用性。为了减轻这些挑战，IEC 61508建立了分析公式，用于估计k -out- n (KooN)架构的平均故障概率。然而，这些公式仅限于具有相同组分的系统，这一局限性在许多研究中尚未得到解决。为此，本文提出了一种基于马尔可夫模型的不同冗余系统体系结构非相同组件不可用性模型，并建立了非相同k-out- n和n-out- n配置的推广公式。此外，该模型还纳入了未被发现的故障率，并评估了其对SIS不可用性量化的影响。用现有的不可用性方法验证了所提模型的准确性，结果表明所提方法对所有系统架构都具有足够的鲁棒性。

This study analyses the economics and determinants of a brewery industry (Guinness Nigeria Limited) with a view of establishing the future of breweries in Nigeria. The specific objectives were to estimate the factors influencing products production and determine the viability of products manufactured by the company. Multiple regression and the ordinary least square techniques were used to analyse the long-term (2006 - 2015) annual time series data observed for the study. The results showed that the major determinant of Stout, Harp and Malt production is demanded. As a significant input, it positively influences product production. The observed values of regression coefficients (R2) are 0.99349 (for Stout), 0.90981 (for Harp), and 0.99498 (for Malt), which indicates that they are reliable for determining the future of Guinness Nigeria Ltd. The results also showed that logarithm of demand for Stout production (LstoutD) of 13.5277, LharpD of 21.8439 and LmaltD of 12.2653 were projected respectively up to the year 2025, an indication that brewery production in the state is viable and that future is bright.
