Research ArticleOpen accessIn the abstractHigh-precision Detection of Facial Landmarks to Estimate Head Motions Based on Vision ModelsXiaohong W. Gao, Sergey Anishenko, Dmitry Shaposhnikov et al.A new approach of determination of head movement is presented from the pictures recorded via digital cameras monitoring the scanning processing of PET. Two human vision models of CIECAMs and BMV are applied to segment the face region via skin colour and to detect local facial landmarks respectively. The developed algorithms are evaluated on the pictures (n=12) monitoring a subject’s … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,819 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study by Electrochemical Impedance Spectroscopy (EIS) On The Corrosion Resistance of Industrial and Laboratory Zinc CoatingsY. Hamlaoui, F. Pedraza, L. TifoutiIn this work, corrosion monitoring of Zn-based coatings is investigated through potentiodynamic and electrochemical impedance spectroscopy (EIS) methods. The first part of the study is devoted to galvanised coatings conventionally manufactured in the industry. The second part focuses on the corrosion resistance of a laboratory-made electrolytic coating. For such purpose, the corrosion behaviour is studied in NaCl media under various … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Value of Serologic Tests for Diagnosis and Follow up of Patients having BrucellosisNidia E. Lucero, Sandra M. Ayala, Gabriela I. Escobar, N R. JacobThough diagnosis of human brucellosis is accurate when the causal agent is isolated, this procedure is not always successful and the most of patients are diagnosed on the basis of rising titres of antibodies in serum. The classical tests used for detection of antibodies to S-Brucella sp., include Rose Bengal (RBT), buffered plate antigen (BPAT), serum agglutination (SAT), 2-mercapto-ethanol (2MET) … …American Journal of Infectious Diseases, Vol. 3, Issue 1 · 31 Mar 2007 · 7,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Characterization of Al Bond Pad Surface Treatment in Electroless Nickel Immersion Gold (ENIG) DepositionM.K. Md Arshad, A. Jalar, I. Ahmad, G. OmarThis study reports a number of experiments that were designed to characterize aluminum bond pad surfaces prior to electroless nickel immersion gold (ENIG). In the ENIG process, aluminum bond pads need special treatment to achieve successful nickel deposition and provide reliable interconnection of under bump metallurgy in advanced packaging. During this treatment process, the aluminum pad was cleaned, activated and … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation and Properties of Copolyanhydrides Based on 2-Hexadecylsuccinic Acid and Sebacic AcidYousef Hamdan, Xiangmei Jiang, Kaixun Huang, Kaichao YuPoly(2-hexadecylsuccinic acid-sebacic acid) (P(HSA-SA)) copolymers have been prepared by melt polycondensation. The copolymers were characterized by FT-IR, 1HNMR, gel permeation chromatography (GPC), differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). In vitro studies showed that all our prepared copolymers are degradable in phosphate buffer at 37°C. The release profiles of hydrophilic model drug, ciprofloxcin hydrochloride, from the copolymers, follow … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,427 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorpho-physiological Differences of the Spermatheca of Attini Ants (Hymenoptera: Myrmicinae)Gabriela Ortiz, Maria Izabel Camargo-MathiasThe insect's spermatheca store the spermatozoa from the time of copulation until the fertilization of the eggs and consists of a sac, usually associated to glands. The ant species Atta laevigata, Atta sexdens sexdens, Atta sexdens piriventris, Acromyrmex coronatus and Cyphomyrmex muelleri are considered pests, as they cause economics losses to several crops. The spermatheca of these species were examined … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 4 · 31 Dec 2006 · 7,583 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Competence-based View to Conflict ManagementWaitchalla R.R.V. Suppiah, Raduan Che RoseThis study presents a review of conflict management from the competence-based perspective. It highlights the conflict management typologies as well as previous studies conducted using the competence model of conflict. There are scant studies using the competence model to conflict management. Previous studies using this model have used students as their respondents and have a Western biasness. …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 7,040 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Basis of Magnetic Resonance Spectroscopy and its Application to Central Nervous System DiseasesNicolás Fayed, Salvador Olmos, Humberto Morales, Pedro J. ModregoMagnetic Resonance Spectroscopy is based on the chemical shift property of the atom nuclei when a magnetic field is applied. This technique offers invaluable information about living tissues with special contribution to the diagnosis and prognosis of the central nervous system diseases. Concentration of several metabolites can be assessed in a reproducible manner by means of modern clinical scanners. N-acetyl-aspartate … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of ball milling times on phase formation of Mg0.7Zn0.3Fe2O4Aurawan Rittidech, Panuthat KhotsongkramMg0.7Zn0.3Fe2O4 (MZF) powder was prepared by a solid-state mixed oxide using ball-milling technique. The phase identification of calcined powders was performed using X-ray diffraction technique (XRD). It has been found that MZF powders were successfully obtained for calcination conditions of 800 oC for milling times of 36 h, whereas milling times of 12 h, unreacted ZnO, Fe2O3 and MgO phases … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Magnetic Paper from Kenaf: Lumen Loading and in situ Synthesis MethodC. H. Chia, S. Zakaria, S. Ahamd et al.Magnetic papers have been successfully prepared from unbleached kenaf (hibiscus cannabinus) kraft pulps via the lumen loading and in situ synthesis process. The lumen loading method allows the magnetic fillers to be introduced into the lumen of fibres and at the same time leaving the external surfaces free from filler, resulting the better inter-fibre bonding and subsequently its papermaking properties … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,514 accessesView PDFCite
