Research ArticleOpen accessEvery word in the titleEras of Material, Energy and Information ProductionSergey K. AityanThis study identifies and discusses three types of production: production of aterial goods, energy, and information. The production timeframes with the reference to each production era are about 103, 102 and 101 years. The necessity of education and the associated level of stress in different production eras were analyzed by comparing a typical length of a human life, which is … …Journal of Social Sciences, Vol. 8, Issue 3 · 28 Jul 2012 · 8,159 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAdhesion and Hardness Evaluation of Modified Silicone-Dammar as Natural Coating MaterialsR. Zakaria, A. H. AhmadProblem statement: Dammar is a natural resin that used anciently in varnish production. The use of dammar natural resin in coating is limited by undesirable properties for application in coating where it is considered very brittle. Due to dammar's brittle nature, an aged dammar coating can be easily scratched or abraded. Approach: Dammar natural resin could be modified into Silicone-Dammar … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 20 Mar 2012 · 7,630 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFuzzy Parametric Deduction for Material Removal Rate OptimizationTian-Syung LanProblem statement: A general optimization scheme without equipment operations for CNC (computer numerical control) finish turning is deemed to be necessarily developed. Approach: In this study, four parameters (cutting depth, feed rate, speed, tool nose runoff) with three levels (low, medium, high) were considered to optimize the Material Removal Rate (MRR) based on L9(34) orthogonal array. Twenty-seven fuzzy control rules … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 31 Jan 2011 · 7,239 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFabrication of Composite Material from Sea Mussel Shells and White Clay as a Versatile SorbentSingto Sakulkhaemaruethai, Churairat Duangduen, Weraporn Pivsa-Art, Sommai Pivsa-ArtProblem statement: The removal of heavy metals contaminated in aqueous solution/wastewater has been causing worldwide concern. However, the adsorbent materials are usually limited due to their high cost and environmentally benign. To overcome the above-mentioned disadvantages, low-cost and effective adsorbents are in demand. Approach: In this study, the sea mussel shells/natural clay beads were prepared for using as low-cost sorbent … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,801 accessesView PDFCite
