Research ArticleOpen accessIn the abstractExpression, Purification and Activity Assay of Two New Recombinant Antagonists of Fibrinogen ReceptorJianbo Yang, Jia Yao, Kun Yang et al.The gene sequence of Decorsin which is extracted from a kind of North American leeches was synthesized. Two recombinant proteins, Annexin V plus Decorsin (AnnV-D39) and Annexin V plus the carboxyl terminal 27 amino acid residues of Decorsin(AnnV-D27), were constructed. And a 10 amino acids linker peptide of GGGGSGGGGS was inserted between Annexin V and Decorsin in AnnV-D39. Using pET-28(a+) … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Investigation of Two-Stage Absorption Refrigeration System Connected by a CompressorL. Kairouani, E. Nehdi, R. B. IffaThe present work is to analyze a two-stage cycle based on the ammonia-water absorption system, with intermediate compression. The two generators of the system are heated by geothermal energy at low temperature. The study shows that this system makes it possible at lower generator temperature, under the limits permitted by the systems suggested up to now. For Tg = 335 … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractDisplacement of Boron from the Silicon Crystal Nodes by Interstitial Si Atoms During Implantation and AnnealingM. Jadan, A. R. Chelyadinskii, V. Y. YavidThe process of boron displacement from the nodes into interstitial positions of interstitial Si atoms in silicon (Watkins effect) on the conditions of implantation and annealing has been investigated with the help of X-ray diffraction and electrical methods. It was revealed that the efficiency of the Watkins substitution is determined by the ion current density (level of ionization). With increasing … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractScheme for ISDN/DECT Wireless Internetworking and VerificationMaher Dababneh, Ibrahim QatawnehA novel scheme to access the basic rate service of the Integrated Service Digital Network (ISDN) using the Digital Enhanced Cordless Telephone (DECT) radio interface standard is presented. The S-interface in the ISDN reference configuration has been used for the ISDN interface and the unprotected class 0 transmissions are used for the DECT interface. The design of a state of … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign Parameters Optimization Simulation of a Prototype Segmented Rubber Track Vehicle for Sepang Peat in MalaysiaAtaur Rahman, Azmi Yahya, Mohd. Zohadie et al.This study describes a simulation model for studying the basic design parameters of a special rubber track vehicle with rigid link tracks system on Sepang peat terrain in Malaysia. The prototype parameters for a track system, including proper track width, ground contact length, pitch and grouser height, idler diameter and location, sprocket diameter and location, road-wheel diameter and geometrical arrangement, … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,928 accessesView PDFCite

A development technology concentrates on minimizing the total costs and provides extended opportunities for improvement of network operation, from the initial planning stage. The study illustrate the mathematical and the algorithm of the branch and bound method with an example to … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,042 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling of Wastewater Oxidation under Microgravity ConditionsBoyun Guo, Donald W. Holder, David S. SchechterVolatile removal assembly (VRA) is a module installed in the International Space Station for removing contaminants (volatile organics) in the wastewater produced by the crew. The VRA contains a slim pack bed reactor to perform catalyst oxidation of the wastewater at elevated pressure and temperature under microgravity conditions. Optimal design of the reactor requires a thorough understanding about how the … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Operational Features of Pumping Stations Equiped with Parallel-Connected Centrifugal Pumps for Land-ReclamationKhalid S. Al-RababaThe required water supply of a pump could be provided by means of different combinations of pressure piping and pumping units at different operational costs. The basic indices describing the operational modes for the individual and group pumping units, including the values of the efficiency, are computed. The adequacy of the calculational results that based on the developed mathematical models … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,802 accessesView PDFCite
