Research ArticleOpen accessEvery word in the titleModeling and Performance Analysis of a Petroleum-Pipeline-Pressure-Boosting Station Powered by Two-Shaft GT EngineYousef S. H. Najjar, Mohammad Z. M. Yousef, Aad M. A. Al-MahgariThis study offers modeling and performance analysis of a pressure-boosting station for petroleum pipelines using a sustainable two-shaft GT engine to drive a three-stage centrifugal pump. The modeling is divided into three steps; matching the GT engine components at the maximum efficiency line, matching the pump performance with the requirements of the pipeline system to generate the pump load curve, … …Energy Research Journal, Vol. 12, Issue 1 · 18 Jan 2022 · 10,510 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreliminary Design of a Power Transmission Shaft under Fatigue Loading Using ASME CodeStephen K. ArmahPower transmission shafting is a vital element of all rotating machinery. A complete shaft design involves many iterative phases and fundamental to this is the determination of preliminary dimensions of the shaft. This paper presents a comprehensive fatigue analysis approach of determining the initial dimensions of a power transmission shaft under fatigue loading based on American Society of Mechanical Engineers … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 7 Feb 2018 · 15,180 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIdentification of Multi-Cracks in the Gate Rotor Shaft Based on the Wavelet Finite Element MethodBin ZhaoIn order to have fault identification for the gate rotor shaft with multiple cracks effectively, the quantity identification method of the gate rotor shaft with multiple cracks based on wavelet finite element method is established and the frequency test of the gate rotor shaft based on blind source separation algorithm is analyzed. Firstly the wavelet finite element was established by … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 12 Sep 2013 · 7,270 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Outcome of Conservative Treatment of Closed Fracture Shaft Humerus in Adult PatientsM. Taha MuzahimProblem statement: Fractures of the humeral shaft are commonly encountered by the orthopaedic surgeons; accounting for approximately 3% of all fractures. There is a wide array of good options for their treatment and controversy over the best methods for many situations. Appropriate nonoperative and operative treatment of patients with humeral shaft fractures, however, requires an understanding of humeral anatomy, the … …Current Research in Medicine, Vol. 2, Issue 1 · 9 May 2011 · 8,016 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHow Does The Bone Shaft Geometry Affect its Bending Properties?Kaveh PourAkbar Saffar, Nima JamilPour, Seyed Mohammad RajaaiIn this research, ten fresh specimens of sheep tibiae were provided from slaughtered animals. Whole bone specimens were loaded in three-point bending according to standard wet bone test protocols. Mechanical properties were determined and compared with the results which were obtained from two dry bone tests. The results showed that fracture bending moment and bone extrinsic stiffness had significant relations … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 8,148 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDevelopment of a Wear Map for the Sliding and Rotational Wear behavior of ShaftsAl-mahasne Mayas MohammadThis study was an attempt to study the wear calculation method for rotating shaft in the friction couple type shaft-cuff in conditions of oiling in high dusty environment. The size and quantity of abrasive particles that go into the clearance between friction surfaces, definition of the pressure including the load in conjugate that is given by the cuff spring as … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,913 accessesView PDFCite

Research ArticleOpen accessIn the keywordsProgress in Relevant Growth Factors Promoting the Growth of Hair FollicleJ. M. Wang, J. T. ZhangHair is a protective appendage on the body that is considered accessory structure of the integument. Hair follicle development takes place during fetal skin development and relies on tightly regulated ectodermal-mesodermal interactions. The morphological changes of the hair cycle have been very clear that hair morphogenesis and epidermal development are orchestrated by an array of growth factors. In this review, … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 2 · 7 Aug 2012 · 7,668 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cartesian Regulator for an Ideal Position-Servo Actuated Didactic Mechatronic Device: Asymptotic Stability AnalysisGabriela Zepeda, Rafael Kelly, Carmen MonroyPosition-servo actuators are by themselves feedback mechatronics systems modeled by Ordinary Differential Equations (ODE). From a technological point of view, position-servos are based upon an electrical motor, a shaft angular position sensor, and a dominant Proportional controller. These position servo actuators are at the core of several real-life practical and didactic mechatronics and robotics systems. The contribution of this study … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 3 · 16 Sep 2022 · 5,821 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Pulsed Electromagnetic Field Exposure on Fracture Healing Through the Wnt Signal PathwayUmiatin U, Ismail Hadisoebroto Dilogo, Puji Sari, Sastra Kusuma WijayaPulsed Electromagnetic Fields (PEMF) is reported to encourage the healing of nonunion fractures. However, the mechanism by which this occurs is still not known. Wnt signaling pathways are believed to be important signaling pathways in bone formation. This study will evaluate the healing of delayed union femur fracture, given PEMF exposure. 48 Spraque Dawley rats were fracturized at the left … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 14 Dec 2020 · 6,653 accessesView PDFCite
