Research ArticleOpen accessIn the abstractDEVELOPMENT OF ARCHIMEDEAN’S PIPE-SCREW FOR THAI SAIL WINDPUMPRonnakorn Thepwong, Issaree Hansacharoonroj, Joseph Khedari et al.This study describes new considerations in the design and development of Archimedean’s Pipe-Screw especially for water pumping in case of low head high volume form open farm pond at Rajamangala University of Technology Rattanakosin, Thailand. The objectives of this research is to develop an Archimedean’s Pipe-Screw especially for water pumping in case of low head high volume form open farm … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 22 Apr 2014 · 7,359 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Lense-Thirring Effect in the Anomalistic Period of Celestial BodiesIoannis Haranas, Omiros Ragos, Ioannis GkigkitzisIn the weak field and slow motion approximation, the general relativistic field equations are linearized, resembling those of the electromagnetic theory. In a way analogous to that of a moving charge generating a magnetic field, a mass-energy current can produce a gravitomagnetic field. In this contribution, the motion of a secondary celestial body is studied under the influence of the … …Space Science International, Vol. 1, Issue 2 · 9 Dec 2013 · 8,459 accessesView PDF Cite

Research ArticleOpen accessIn the abstractResonance Caused by the Gravitational waves On an Earth SatelliteMohamad RadwanThe present work deals with the motion of an Earth satellite taking into account the oblateness of the Earth and of a passing Gravitational wave. The oblateness of the Earth is truncated beyond the second zonal harmonic, J2, which plays the role of the small parameter of the problem. The conditions for resonance are determined and the resonance resulting from … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 6,775 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRelation between Autoimmunity Chronic Urticaria and the Levels of Plasma Prothrombin F1+2Liu Xiaoming, Sheng Wanxiang, Ahmad T. Khalaf et al.A number of recent epidemiologic and experimental studies have enhanced our knowledge of the etiology and pathogenesis of chronic urticaria (CU), a disease that imposes profound impairment on patient's quality of life. Our study was performed to explore the relation between autoimmunity (CU) and the levels of plasma prothrombin F1+2. Thirty four (CU) patients with positive autologous serum skin test … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,900 accessesView PDF Cite
