Over this recent year, a growing population that increase the economic development, capacity of landfills and critical environmental impact are gaining the importance role of remanufacturing activities. Moreover, many durable products are disposed in landfills at the end of their useful lives without undergoing by any recovery process that affect the landfill space has been decreasing in all over the world including by our country. Remanufacturing is the process by which used products are returned to their new state with minimum waste and expenditure on materials and energy. This study focus on the concept concept of remanufacturing practice in automotive sector. Malaysians have been generated wastes at a manufacturing sector especially in the automotive sector. On top of that, the conventional remanufacturing systems that have been constructed in Malaysia are not widely marketed and lack of practical applications. This study provides a remanufacturing analysis for improvement to the automotive sectors on engine block. Furthermore, this study presents the information based on the discussion of Failure Mode and Effects Analysis (FMEA) to encourage the implementation of remanufacturing activities. By making the remanufacturing activities possible to implement efficiently, manufacturer may decrease their production costs, decrease refuse and landfill materials, and increase their quality management.

AbstractIn industry, Failure Mode and Effects Analysis is an established quality tool for minimizing development risks in systems, products and processes. Nevertheless, the presented use case shows that the application of the FMEA method in the development of Product-Service Systems in a SME requires modifications to ensure that the special character of PSS is appropriately included and that risks can be adequately assessed and prioritized.

: The electrodes are the basis for building flexible lithium-ion batteries (FLIBs), and many attempts have been made to develop flexible electrodes with high efficiency in terms of electrical conductivity, chemical and mechanical properties. Most studies showed relatively satisfactory results when testing the electrochemical properties of laboratory-produced electrodes, but most of these electrodes could not meet the expected requirements of flexible electrodes in practical applications. Quantitative production faces many problems that must be overcome, such as the gradual decline in electrochemical performance, deformation of the electrode structure, high production costs, and difficulties in the production process itself. In this research, developments in the production of flexible electrodes, especially those that depend on carbon materials and metal nanoparticles, will be discussed and summarized in this research. The electrochemical performance and stability of the produced flexible electrodes will be compared. The factors contributing to the progress in the production of flexible lithium-ion batteries will also be discussed.

The paper aims at presenting the FMEA method based on the fuzzy technique, representing a new approach to the failure analysis and its effects on the observed system. The FMEA (Failure Mode and Effect Analysis) method has assigned the risks a coefficient i.e. a numerical indicator that very clearly defines the degree of risk. The risk is calculated as a mathematical function of RPN which depends on the effects S, probability O that some case will lead to a failure and to a probability that a failure D can not be detected before its effects are realized. RPN = S O D. The FMEA method, based on the fuzzy logic, makes a more reliable evaluation of the observed system failures possible.

Villiger Oxidation

Na2SeSO3, which can be generated in situ by the reaction of Na2SO3 with Se power, was found to be an odorless reagent for the selenenylation of alkyl halides to produce dialkyl diselenides. These products have been recently shown to be good catalysts for the Baeyer–Villiger oxidation of carbonyl compounds, for the selective oxidation of alkenes, or for the oxidative deoximation of oximes. By using aqueous EtOH as the solvent and avoiding the generation of a malodourous selenol intermediate, the selenylation reaction with Na2SeSO3 is much more environmentally friendly than conventional methods. Owing to the cheap and abundant starting materials and selenium reagents, our novel synthetic method reduces the production costs of dialkyl diselenides as organoselenium catalysts, thereby advancing practical applications of organoselenium-catalysis technologies.

Failure mode and effect analysis is one of the QS-9000 quality system requirement supplements, with a wide applicability in all industrial fields. FMEA is the inductive failure analysis instruments which can be defined as a methodical group of activities intended to recognize and evaluate the potential failure modes of a product/ process and its effects with an aim to identify actions which could eliminate or reduce the chance of the potential failure before the problem occur. The purpose of this paper is to evaluate the FMEA research and application in the Thermal Power Plant Industry. The research will highlight the application of FMEA method to water tubes (WT) in boilers with an aim to find-out all the major and primary causes of boiler failure and reduce the breakdown for continuous power generation in the plant. Failure Mode and Effect Analysis technique is applied on most critical or serious parts (components) of the plant which having highest Risk Priority Number (RPN). Comparison is made between the quantitative results of FMEA and reliability field data from real tube systems. These results are discussed to establish relationships which are useful for future water tube designs.
