Research ArticleOpen accessIn the abstractThe Functionality of Fiber Bragg Grating Sensor Compared to that of Foil GaugeBashir Ahmed Tahir, Jalil Ali, Rosly Abdul RahmanTechnology such as Fiber Bragg Grating (FBG) sensors are widely accepted in almost all industries. FBG are being investigated for their applicability in other markets such as smart structures. Fiber optic sensors can also be used in many different applications. Fiber optic sensors are available in several types; among them, the Bragg grating sensor is being studied in this research. … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractCPU Cooling of Desktop PC by Closed-end Oscillating Heat-pipe (CEOHP)S. Rittidech, A. Boonyaem, P. TipnetThe CEOHP cooling module consisted of two main parts, i.e., the aluminum housing and the CEOHP. The house casing was designed to be suitable for CEOHP. The housing to drilling for insert the CEOHP. The CEOHP design employed copper tubes: Two sets of capillary tubes with an inner diameter of 0.002 m, an evaporator length of 0.05 and a condenser … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 8,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Effect of Counterface Materials on Interface Temperature and Friction Coefficient of GFRE Composite Under Dry Sliding ContactN. S.M. El-Tayeb, B. F. Yousif, P. V. BrevernNowadays, there is an increase interest in polymeric composite materials for high-performance in many industrial applications. In other words, the tribo-studies on polymeric materials are growing fast to enhance the polymeric products such as bearings, seals, ring and bushes. The current work presents an attempt to study the correlation between the type of counterface material and frictional heating at the … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,023 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval of Mercury from chlor-alkali Industry Wastewater using Acetobacter xylinum CelluloseA. Rezaee, J. Derayat, S. B. Mortazavi et al.In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function of pH, adsorbent dose and contact time. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 8,283 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation and Characterization of Hybrid Organic-Inorganic Composite Material: Polymerization of m-Aminobenzoic Acid-Intercalated Into Zn/Al-Layered Double HydroxidesRasheed M.A.Q. JamhourLayered double hydroxides of aluminum and zinc (Zn/Al-LDH’s) were synthesized directly by hydrolysis at room temperature as reported elsewhere. After characterization, the material was reacted with m-aminobenzoat anion (m-NH2C6H4COO-) which undergoes polymerization in the interlayer space; resulting in the formation of a matrix with polymeric organic macromolecule. The resulting material along with the host LDH’s compound of Zn/Al-Cl was characterized … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,586 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon Destructive Tests of Structural Bonds by Guided Ultrasonic Waves: Effect of a Surface Pretreatment or a Localized DefectValentina Vlasie, Martine RousseauThe aim of this study was to propose a non destructive method to test the mechanical quality of a bond aluminium/epoxy/aluminium. Thus, for each aluminium/epoxy interface, an intermediate interface modelling between a simple geometrical interface and an interphase (3D material medium), i.e. a 2D material medium. In order to describe the surface stresses, we introduce the surface free energy (the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,883 accessesView PDFCite
