Research ArticleOpen accessEvery word in the titleUse of the Nere Pod (Parkia Biglobosa) for the Improvement of Mechanical Properties of SoilsSinko Banakinao, Sonnou Tiem, Kodjo Attipou et al.Buildings made of unbaked clay have some advantage in terms of production cost. However, they have some inconveniences concerning their mechanical performance, particularly their resistance to weather. The objective of this study is to minimize these disadvantages and to maximize the benefits of such buildings to make them more viable. For this purpose, a method based on a traditional practice … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 16 Feb 2017 · 7,851 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSomething about the Mechanical Moment of InertiaFlorian Ion T. Petrescu, Antonio Apicella, Aversa Raffaella et al.In this study, the relations to determining mass moments of inertia (mechanical) for different mass and mechanical inertia corresponding to geometric shapes, objects and profiles are explored. The formulas for calculating the mass moments of inertia (mechanical) for various bodies (various geometrical forms), to certain major axis indicated (as the axis of calculation) are presented. The total mass M of … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 4 Nov 2016 · 11,376 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Mechanical Properties of Aluminium Alloy 2024 Reinforced with Silicon Carbide and Fly Ash Hybrid Metal Matrix CompositesM. Mahendra Boopathi, K.P. Arulshri, N. IyanduraiMaterials are frequently chosen for structural applications because they have desirable combinations of mechanical characteristics. Development of hybrid metal matrix composites has become an important area of research interest in Materials Science. In view of this, the present study focuses on the formation of aluminium-Sic-fly ash hybrid metal matrix composites. The present study was aimed at evaluating the physical properties … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 8 Mar 2013 · 28,510 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDevelopment of Nanostructured Stress Free Pt-Rich FePt Films for Micro Electro Mechanical System ApplicationsT. M. Selvakumari, R. N. Emerson, S. GanesanProblem statement: The electroplating technique is especially interesting due to its low cost, high throughput and high quality of deposit. Magnetic thin films are extensively used in various electronic devices including high density recording media and Micro Electro Mechanical (MEMS) devices. So we examined FePt films and give good magnetic properties. Approach: The Pt-rich FePt alloys were electrodeposited galvanostatically by … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,683 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImproving Mechanical Characteristics of Inverter-induction Motor Drive SystemHussein Sarhan, Rateb IssaAn inverter-three-phase squirrel-cage induction motor drive system with improved mechanical characteristics is presented. The proposed system provides mechanical characteristics with constant maximum torque or increased maximum torque and reduced slip speed at frequencies below the nominal frequency. The control algorithm is based on the constant volts per hertz principle using two improvement techniques: keeping maximum torque constant or keeping magnetic … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 7,659 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStatic and Dynamic Mechanical Behavior of Hydroxyapatite-Polyacrylic Acid Composites Under Simulated Body FluidKalpana S. Katti, Phanikumar Turlapati, Devendra Verma et al.In this work, we have investigated mechanical response of hydroxyapatite/polyacrylic composites under dry, wet and simulated body fluid conditions. Hydroxyapatite (HAP) is mineralized under two conditions; one, in presence of polyacrylic acid (in situ HAP), second, in absence of polyacrylic acid (ex situ HAP). Further, in situ and ex situ HAP are mixed with polyacrylic acid to make HAP/PAAc composites. … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 7,395 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMechanically Stimulated Osteoblast Cells GrowthRaffaella Aversa, Antonio Apicella, Francesco Tamburrino, Florian Ion Tiberiu PetrescuThe bones need to be built and then permanently restored to keep them functioning properly. Considering the multiple bone functions, their vitality is essential both to maintain the body and move it and to maintain its health and vigor. When most bones begin to age and have no vital function, the man also begins to age, lose water, minerals, electrolytes, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 19 Jun 2018 · 7,882 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleTHE STRUCTURE AND MECHANICAL PROPERTIES OF ALUMINA FILM PREPARED BY RF DIODE SPUTTERINGH. Panitchakan, P. LimsuwanAlumina (Al2O3) films were prepared on Al2O3-TiC substrates by RF diode sputtering. The target sputtering power was varied from 4 to 8 kW. The effects of target sputtering power on the structure and mechanical properties of alumina films were investigated. The results show that the structure of the alumina films deposited at all the target sputtering powers is amorphous. However, … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 6,897 accessesView PDFCite
