However, recent studies have shown that asbestos poses a great health hazard which can result from its handling and breathing (NIH, 1989). As a result, it has lost its favor, resulting in the need to explore alternative materials. Hence, efforts by researcher have been geared toward finding a possible replacement for asbestos in the production of brake linings. These were exemplified by the work of several researchers who utilized other materials such as palm kernel shell (PKS), coconut shell, metal fibers, etc., for inclusion in brake lining in order to overcome environmental pollution (Ikpambese et al., 2016; Fono-Tamo and Koya, 2013). Also, a non-asbestos friction lining material was developed by Ibhadode and Dagwa (2008) using an agro-waste material–palm kernel shell, as a reinforcement material. Palm kernel shell (PKS) which was used as a reinforcement material was selected due to its favorable properties which superseded other agro-waste. The developed automobile disk brake pads using the derived friction material and the test results obtained indicated that high wear rate was observed on the PKS pad at high vehicular speeds of 80 km h À1 and above. Zaharudin et al.(2012) adopted Taguchi method to carry out a study on the effect of manufacturing parameters on the properties of friction materials. The parameters studied were molding pressure, molding temperature, and the molding time using semi-metallic friction materials and other additives. Physical properties such as … 2016-01-01T00:00:00Z http://irepo.futminna.edu.ng:8080/jspui/handle/123456789/18122 Title: Rubber Tires Authors: Rodgers, M.

A. Abstract: Adoption of any management strategy needs a framework as a blue print for its implementation and usually driven by the management. Therefore, this paper is aimed at presenting the role of top management commitment on implementation of Total Quality Management (TQM). This management philosophy is mainly concerned with continuous improvement in an organization, from high level strategic planning and decision-making to detailed execution of work elements on every level of the organization. An investigatory survey research approach (ISRA) method was adopted for the quantitative and qualitative data collection and collation from Shirror Hydroelectric Power Plant PLC. of Nigeria. It was ascertained that top/middle management commitment is a fundamental factor to be considered by an organization to implementation TQM. 2013-11-01T00:00:00Z http://irepo.futminna.edu.ng:8080/jspui/handle/123456789/16981 Title: Gas Turbine Engine: Design, Application and Performance Analysis Authors: Nasir, A.; Mohammed, A; Jiya, J. Y. Abstract: Gas Turbines (GT) are thermally rated air breathing engine which generates motive power from the combustion of fuel and expansion of gases. Gas turbines are employed in different spares of our daily lives, yet many people are unaware of the cutting-edge technologies used in the creation and operation of these engines. This article explains the principle involved with emphasis on the operation and performance analysis. The application of GT ranges from its use in power generation to aircraft propulsion, ship propulsion, gas compression in pipeline or tankers and others. GT is hugely affected by ambient conditions such as increase or decrease in ambient temperature. The operation of GT follows the Bryton cycle and detail is given in the paper. The effect of increase in ambient temperature on GT performance has been analyzed and discussed. As the ambient temperature increase, the mass flow reduces and therefore the performance of the GT drops 2019-01-01T00:00:00Z
