Research ArticleOpen accessIn the abstractCharacterization and Geotechnical Properties of Penang Residual Soils with Emphasis on LandslidesFauziah Ahmad, Ahmad Shukri Yahaya, Mohd Ahmadullah FarooqiThe predominantly hilly terrain of Penang Island combined with average maximum daily temperatures ranging between 27-35°C and peak rainfall as high as 647 cm makes the overall area potentially susceptible to landslips. Over the recent past construction industry has shown a rapid growth mainly due to increase in the inflow of international tourists and other economic reasons. Eventually, the magnitude … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 8,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractUpgrading of Light Dewaxed Oil through Hydrofinishing and Additives Blending for Producing Automatic Transmission FluidGamal Abdel-Nasser Gohar, Mohamed Sherif El-Gayar, Abd El-Moneim Ibrahim et al.Light dewaxed oil was produced through dewaxing process of the light waxy distillate raffinate of crude oil from Western Desert of Egypt using methyl ethyl ketone/toluene mixed solvent. Hydrofinishing process was used to remove the non-hydrocarbon constituents and to improve the physicochemical properties of the produced oils such as color, viscosity index, inhibition responses, oxidation and thermal stability. The operating … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractChaotic Attitude Tumbling of Satellite in Magnetic FieldRashmi Bhardwaj, Parsan KaurIn this study, the half width of the chaotic separatrix has been estimated by chrikov's criterion. Through surface of section method, it has been observed that the magnetic torque parameter, the eccentricity of the orbit and the mass distribution parameter play an important in changing the regular motion into chaotic one. …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 6,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractRotational Linear Discriminant Analysis Using Bayes Rule for Dimensionality ReductionAlok Sharma, Kuldip K. PaliwalLinear discriminant analysis (LDA) finds an orientation that projects high dimensional feature vectors to reduced dimensional feature space in such a way that the overlapping between the classes in this feature space is minimum. This overlapping is usually finite and produces finite classification error which is further minimized by rotational LDA technique. This rotational LDA technique rotates the classes individually … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment on Biocides Bioaccumulation in Mullet Liza klunzingeri in Kuwaiti Waters, off the Arabian GulfA.H. Bu-Olayan, B. V. ThomasBiocides, such as formaldehyde (HCHO), sodium hypochlorite (NaOCl) and glutaraldehyde (C5H8O2) that are commonly used in thermal, desalination and power plants and industries were tested on the commercially important mullet fish, Liza klunzingeri to determine the environmental contamination in the stressed ecosystem of Kuwait Bay sites. Multi-factor Probit analysis toxicity tests (96 h) on L. klunzingeri showed the lowest observed … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistributed Clusterhead Architecture for Mobile Ad Hoc NetworksEmad Qaddoura, Wesam AlMobaideen, Ahmad OmariMobile Ad Hoc Network (MANET) consists of dynamic topology as nodes in the network are mobile, and connected via wireless links. The nodes are grouped in clusters for the purpose of routing. Nodes within the cluster communicate directly. However, nodes communicate outside the cluster through a centralized node that is called a clusterhead. An elected clusterhead is assigned for communication … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Fluoride and Other Ions on Algae and Fish of Coastal Water of Mediterranean Sea, EgyptM. S. Masoud, W. M. El-Sarraf, A. A. Harfoush, G. F. El-SaidSea grass, marine algae and fish samples were collected from the Egyptian coast of Mediterranean Sea during September 2000 and March 2001. The contents of fluoride and some interfering ions (calcium, magnesium, sulphate, phosphorus and some heavy metals) ions and their concentration factors were determined in the dried samples. Fluoride contents in macrophytes, algae, muscle of fish samples were ranged … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabrication of 3-D Porous Mg/Zn doped Tricalcium Phosphate Bone-Scaffolds via the Fused Deposition ModellingSamar Jyoti Kalita, Melissa FergusonThree dimensionally interconnected porous resorbable beta-tricalcium phosphate (β-TCP) ceramic scaffolds were developed using the indirect fused deposition modelling process. β-TCP was doped with Mg and Zn, separately, to improve its sintering kinetics and facilitate fabrication of viable porous scaffolds. Effects of Mg and Zn on sintering kinetics and densification of β-TCP were studied. Fabricated porous scaffolds were tested for their … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,926 accessesView PDFCite

Research ArticleOpen accessIn the abstractDynamic Solution Code for Structural Analysis upon Joint ElementS. A. Sadrnejad, M. LabibzadehThe analysis of large structures mostly requires a complete three dimensional finite element discretization. Stability of such structures includes not only the stability of structure itself but also that of foundation as well as interconnection elements. The general instability of a structure may be affected by two aspects, firstly, an inappropriate preliminary classical design of the structure and inadequate control … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,442 accessesView PDFCite
