Research ArticleOpen accessIn the abstractInhibition of U6 snRNA Transcription by PTENStephanie Cabarcas, Kounosuke Watabe, Laura SchrammProblem statement: RNA polymerase III (RNA pol III) is responsible for transcribing many of the small structural RNA molecules involved in RNA processing and protein translation, thereby regulating the growth rate of a cell. RNA pol III transcribes both gene internal (tRNA) and gene external (U6 snRNA) promoters and proper initiation by RNA polymerase III requires the transcription initiation factor … …OnLine Journal of Biological Sciences, Vol. 10, Issue 3 · 30 Sep 2010 · 8,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntervention Model for Analyzing the Impact of Terrorism to Tourism IndustryZ. Ismail, Suhartono, A. Yahaya, R. EfendiProblem statement: It is common in time series data with extreme change in its mean caused by an intervention which comes from external and/or internal factors. This extreme change in mean is known as regime change or structural change. Problems of external factor intervention such as the effect of the Arab oil embargo to consumption level of electricity in United … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,944 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Factors and Limbic Vulnerability in Childhood AutismRichard LatheThe rise in prevalence of autism spectrum disorders (ASD) is suggestive of a new etiology. Diagnostic substitution alone is unlikely to account for the increase, while genetic association with detoxification gene alleles points to an environmental contribution. Subtle structural anomalies in the ASD brain are widespread but limbic damage seems important for the development of behaviors diagnostic of ASD. The … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 7,678 accessesView PDFCite
Research NotesOpen accessAll words, across the recordA Study on Fabrication and Structural Characterization of PbS Thin FilmsMustika Wati, Kamsul AbrahaPbS thin films are fabricated from 99.9% PbS powder on glass substrates using the vacuum evaporation method. Some of the samples are then treated in an advanced process called annealing. Samples are annealed in temperatures of 80, 100, 120 and 150°C for two h. Characterization using an X-Ray Diffractometer (XRD) resulted in values of lattice constant of the films ranging … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 20 Nov 2017 · 7,847 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordForces of a 3R RobotRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.In this study, one presents a method for determination of kinetostatic parameters in dyad 3R. It starts with the determination of the forces in the joints: RB, RD, R23. To generalize the method including for the 2R robots, enter both the moments M1, M2. This module (2R) is the main module found in all rotating anthropomorphic robotic structures and similar … …Journal of Mechatronics and Robotics, Vol. 1, Issue 1 · 8 Nov 2017 · 7,738 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordStructural Dynamics of the Distribution Mechanism with Rocking Tappet with RollFlorian Ion T. Petrescu, John Kaiser Calautit, Dragan MarinkovicIn this study, the authors present a new method to dynamically synthesize a mechanism with rotary cam and rotated tappet with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. This type of distribution can improve the changes of gases and may decrease significantly the level of vibration, noises and emissions. As long as … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 28 Oct 2015 · 9,290 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMulti-Objective Optimization of FRP Jackets for Improving the Seismic Response of Reinforced Concrete FramesCorrado Chisari, Chiara BedonIn this study, a multi-objective Genetic Algorithm (GA) optimization procedure is proposed for the seismic retrofitting of Reinforced Concrete (RC) building frames via Fiber-Reinforced Polymer (FRP) jackets. The optimization problem is solved via numerically efficient but accurate Finite-Element (FE) models able to take into account the strengthening and ductility increase contribution for a given FRP jacketing configuration.
