Research ArticleOpen accessIn the abstractPDX-1 and MafA: Key Transcription Factors in PancreasHideaki Kaneto, Takeshi Miyatsuka, Yoshihisa Nakatani, Taka-aki MatsuokaPancreatic and duodenal homeobox factor-1 (PDX-1) plays a crucial role in pancreas development, β-cell differentiation and in maintaining normal β-cell function by regulating several β-cell-related genes including insulin. PDX-1 has potency to induce insulin-producing cells in non β-cells in various tissues such as pancreas and liver and PDX-1-VP16 fusion protein more efficiently induces insulin-producing cells, especially in the presence of … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 7,389 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological Database and Quantification of Liberica Coffee Beans Using a Hybrid CNN ModelDioneces O. Alimoren, Francis G. Balazon, Jonnah R. Melo et al.Traditional evaluation of Liberica coffee (Kapeng Barako) in Batangas is commonly performed through manual visual inspection and sensory judgment, which are slow, subjective, and difficult to reproduce across farms, buyers, and grading personnel. These limitations can lead to inconsistent quality classification, weak traceability, and reduced bargaining power for local producers. This study develops and validates a web-based morphological analysis system … …Journal of Computer Science, Vol. 22, Issue 8 · 24 Aug 2026 · 1,337 accessesView PDFCite
Research ArticleOpen accessIn the abstractWireless Communication with a Microprocessor Based Ultrasonic Meter for Flow MeasurementsMahmoud Z. IskandaraniProblem statement: Although the traditional metering system and method for controlling flow is generally safe, reliable and robust, it does suffer certain drawbacks, such as limited accuracy and the ability to implement complex reactive rate designs. Hence, there is a need for a circuit and method of increasing metering accuracy, as well as the position control accuracy for variable flow … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractFracture and springback on Double Bulge Tube Hydro-FormingF. Djavanroodi, M. GheisaryThis research aims to establish a basic understanding of Double Bulge Tube Hydro-Form processing of stainless steel deep drawn cups. The method is briefly reviewed by carrying out experimental tests and Finite element analysis. By measuring bulge height in both formed curves by Coordinate measuring machine (CMM) and thickness variation specimen by Ulterasonic thickness measurment device (UTM), it has been … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical and Numerical Analysis of Free Bulge Tube HydroformingF. Djavanroodi, M. Gheisary, H. Zoghi-shalFree bulge hydroforming simulation was analysied to investigate the biaxial behavior of extruded aluminum tubes. A finite element model was constructed to simulate the hydroforming process and asses the influence of friction between die walls and tube, tube material properties and springback of formed tube. It was found that material hardening coefficient had the most significant influence on formability characteristics … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,863 accessesView PDFCite
Research ArticleOpen accessIn the abstractClosed Die Forging Geometrical Parameters Optimization for Al-MMCM. Jolgaf, S.B. Sulaiman, M.K.A Ariffin, A.A. FaiezaDemand for lighter and stiffer products has been increasing in the last few years especially in automobile manufacturing. The closed die forging process of Metal Matrix Material (MMC) is presented as possible solution, since it produces parts with good mechanical properties and lighter weight. A computational modeling of closed die forging process using finite element method and optimization techniques makes … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 8,477 accessesView PDFCite
