Research ArticleOpen accessIn the abstractPitch and Timbre Determination of the AngklungMohd Ridzuwary Mohd Zainal, Salina Abdul Samad, Aini Hussain, Che Husna AzhariThis research describes the pitch and timbre determination of the angklung, a musical instrument made entirely out of bamboo. An angklung has two main parts: the frame and the rattle tubes. The pitch of the rattle tubes can be determined using a formula that takes into consideration the length and diameter of the air resonator. This is compared with the … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 9,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Energy Storage in the Ground of a Greenhouse by the Polypropylene Capillary Heat ExchangerM. Lazâar, S. Koôli, M. Hazami et al.The problem of temperature inversion is one of solar origin principal problems about which the cultures under shelters complain. Indeed, for the winter period, the temperature under greenhouse is very low at night and it is rather high during the day in summer. Consequently, the heating of the greenhouses is essential. In this work, we studied the advisability of using … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,944 accessesView PDFCite
Research ArticleOpen accessIn the abstractCPU Cooling of Desktop PC by Closed-end Oscillating Heat-pipe (CEOHP)S. Rittidech, A. Boonyaem, P. TipnetThe CEOHP cooling module consisted of two main parts, i.e., the aluminum housing and the CEOHP. The house casing was designed to be suitable for CEOHP. The housing to drilling for insert the CEOHP. The CEOHP design employed copper tubes: Two sets of capillary tubes with an inner diameter of 0.002 m, an evaporator length of 0.05 and a condenser … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 8,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Pulsed Laser Deposition System for the Formation of Web-liked Carbon NanotubesNoorhana Yahya, Beh Hoe Guan, Mansor HashimThis work reports on our earnest effort to develop a pulsed laser ablation deposition system for the production of carbon nanotubes (CNTs). The correct condition such as the pressure, ablation time, power of laser will result in different structures and morphology of the tubes. A T-shaped stainless steel chamber was designed. Nd:YAG laser with 532 nm wavelength, 10.54W output power … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,037 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltra Low Power Single Edge Triggered Delay Flip Flop Based Shift Registers Using 10-Nanometer Carbon Nano Tube Field Effect TransistorRavi Thiyagarajan, Kannan VeerappanCarbon Nano Tube Field Effect Transistor is currently considered as promising successor of Metal Oxide Semiconductor Field Effect Transistor. The scaling down of the Metal Oxide Semiconductor device faced serious limits like short channel effect, tunnelling through gate oxide layer, associated leakage currents and power dissipation when its dimension shrink down to 22 nanometer range. Further scaling of Metal Oxide … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 14 Oct 2013 · 6,756 accessesView PDFCite
Research ArticleOpen accessIn the abstractWaste Heat Recovery from Boiler of Large-Scale Textile IndustryPrateep Pattanapunt, Kanokorn Hussaro, Tika Bunnakand, Sombat TeekasapMany industrial heating processes generate waste energy in textile industry; especially exhaust gas from the boiler at the same time reducing global warming. Therefore, this article will present a study the way to recovery heat waste from boiler exhaust gas by mean of shell and tube heat exchanger. Exhaust gas from boiler dyeing process, which carries a large amount of … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 21 Jun 2013 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Laser Therapy in Inflamed Tissue by Medications Based on Iodoform Laser Therapy in Inflamed TissuePablicia Juliana Santos Tomaz, Michelle de Paula Farias, Marta Rabello Piva et al.This study aimed to evaluate the inflammatory response of the subcutaneous tissue of twenty rats when the use of iodoform with different drugs or not associated with laser photobiomodulation. In the dorsum of rats were introduced into tubes containing: Iodoform and calcium hydroxide (Ca (OH)2); Iodoform and Ca(OH)2, associated with Laser; Iodoform and Otosporin; Iodoform and Otosporin, associated with Laser. … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 18 Jan 2013 · 6,949 accessesView PDFCite
Research ArticleOpen accessIn the abstractRespiratory Tract-Widening Effects of Dihydroartemisinin in Wistar Albino RatsUtoh-Nedosa Uchechukwu, Njoku Goddy, S. Nedosa Kenechi et al.Problem statement: Artemisinin-based anti-malarials are currently widely used in Asia and Africa. Not much is known about the systemic effect of dihydroartemisinin. This study therefore examine the effect of dihydroartemisinin on the lungs of Wistar albino rats. Approach: Five dosages of Dihydroartemisinin (DHA) were administered by oral intubation for 5 days to 5 test and 4 control Wistar albino rats. … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 2 · 17 Aug 2011 · 7,517 accessesView PDFCite
