Research ArticleOpen accessIn the abstractApplication of RNA-DNA Duplex Base Triplets to Antisense DrugsJie Yang, Yao Leng, Ju BaoSixty-four sets of three-dimensional models of RNA-DNA duplex base triplets were constructed based on codons by homology modeling method using software InsightII on Indigo workstation, which should be helpful for the study of RNA-DNA annealing, the basis of nucleic acids interactions and some peculiar motifs for design antisense oligonucleotides. Our research result reveal that the energies (such as E, Ec, … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,534 accessesView PDFCite
Research ArticleOpen accessIn the abstractGender Differences in Baseline Levels of Vascular Endothelial Growth Factor in the Plasma of Alaskan Sled DogsScott W. Kemp, Arleigh J. Reynolds, Lawrence K. DuffyAngiogenesis and vasculogenesis are two very important processes in the development and maintenance of mammalian health. In sled dogs, the angiogenic role is to supply and support tissue with ample vasculature, thus providing a route of access for the transportation of essential nutrients, including oxygen and the removal of waste in a sustained fashion. VEGF has been shown to be … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Analysis of Pressure Pulses in the Jerk Fuel Injection SystemsR. A. Baker, T. FirozComputer software has been developed and described in the present study of thorough parametric analysis and design of a mechanical diesel fuel injection system. The method is based on the numerical solution of one dimensional, unsteady, incompressible flow equations through the fuel pipe along with appropriate initial condition, pump end boundary condition and nozzle end boundary condition. Method of characteristics … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study for Allocating Resources in Research and Development Programs by Integrated Subjective and Objective Decision MethodChun-Chu LiuA decision model is developed to help managers select the most appropriate sequences of plans for product Research and Development (R and D) projects that have strict constraints on budget, time, and resources. In recent years, many organizations have changed from a discipline orientation to a focus on integrated programs and related outcomes. For decision-maker of these high-profile R and … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrency Substitution in TurkeyIsmail H. Genc, Hasan Sahin, Turan ErolWe investigated whether the recent depreciations in the Turkish currency (Lira) resulted in the currency substitution away from Lira by using quarterly data over the period from 1987:1 to 2000: 2 with M1 and M2 monetary aggregates and income, interest rate and exchange rate. Other than the variety of monetary aggregates, we tried different ways of including the interest rate … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,973 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Spectrophotometric Method for Determination of Iron in Herbs, Spices and Beans with 2,6-Diacetylprydine Dioxime and 2-Acetylpyridine MonoximeZ. R. Komy, E. A. Abu-Gharib, A. DesokyThe reaction of iron (II) with 2, 6-diacetylprydine dioxime (H2dapd) and 2-acetylprydine monoxime (Hapm) in 10% and 60% v/v ethanol-water solution at pH 2.5 and 7.5, respectively, were studied using direct and first derivative spectrophotometry. Fe (III) is reduced by H2dapd and gives iron (II) complex. A simple, rapid, selective and sensitive method for the determination of Fe (II), Fe … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractMacroeconomic Variables Analysis in Ukraine: An Empirical Approach with Cointegration MethodNikolaos Dritsakis, Katerina GialetakiThis study investigates the relationship among exports, economic growth, investments and employment in a former country of the Soviet Union such as Ukraine. The purpose of this study was to examine the long-run relationship between these variables using quarterly data for the period 1991:I-2000:IV and applying the cointegration analysis as suggested by Johansen and Juselious. Then a multivariate autoregressive vector … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,710 accessesView PDFCite
Research ArticleOpen accessIn the abstractSystem Availability in the Presence of Estimating Common-cause Time-varying Failure RatesM. A. El-Damcese, Kh. A. Abd AlttifThis study presents a method for calculating the availability of a system depicted by availability block diagram, with identically distributed components, in the presence of estimating common cause hazard, we use the Marshall and Olkin formulation of the multivariate exponential distribution. That is, the components are subject to failure by Poisson failure processes that govern simultaneous failure of a specific … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Solar Radiation SystemM.S. Alam, Sushanta Kumar Saha, M.A.K. Chowdhury et al.In this research work, a mathematical model for simulation of the solar radiation system has been developed by using a system dynamics methodology. Bangladesh is used here for model validation. The simulated results obtained from this model have compared with the experimental results and found reasonably a good agreement. Therefore the performance of the model is to be expected as … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractKernel Density Estimation for Interdeparture Time of GI/G/1 QueuesHsing Luh, Berlin WuThe departure process of a single queue has been studied since the 1960s. Due to its inherent complexity, closed form solutions for the distribution of the departure process are nearly intractable. In this study, kernel type estimators of the density of interdeparture time in a GI/G/1 queue are studied. Uniform strong consistency of the estimators in a GI/G/1 queue and … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,589 accessesView PDFCite
