Research ArticleOpen accessEvery word in the titleDevelopment of an Air Assisted Fuel Atomizer (Liquid Siphon Type) for a Continuous CombustorPipatpong Watanawanyoo, Sumpun Chaitep, Hiroyuki HiraharaThis research was the study of a fuel injection system in continuous combustor. Air atomizing nozzle is developed to good efficiency injection and used low air pressure (68.95-275.79kPa) to assist the atomizing nozzle. Refined palm oil and automotive diesel oil were the fuels for the experiment for the system of atomization. The atomizer was designed in a manner that air … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,544 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Diffusion Coefficient using Reversed-Flow Gas Chromatography-A ReviewKhalisanni Khalid, Rashid Atta Khan, Sharifuddin Mohd. ZainProblem statement: Since the earliest publication on the technique, Reversed-Flow Gas Chromatography (RF-GC) has been used to determine physicochemical properties by measuring the value of one in the presence of another. The method is precise, accurate and simple compared to other conventional techniques. Approach: The experimental setup consists of a small modification of a commercial gas chromatograph, so that it … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcaricidal Activity of Azadirachta indica (Neem Tree) and Carica papaya (Papaya) Leaf Extracts against Rhipicephalus sanguineus (Dog Ticks) Using Spray MethodAlfredo Vita Corpuz, Carmela Montoya Florentino, Paul Erman Tabuloc Quilana et al.Ticks pose a serious threat to dogs, with synthetic acaricides leading to environmental impact and resistance concerns. While Azadirachta indica and Carica papaya have shown acaricidal potential against Rhipicephalus sanguineus, their efficacy against dog ticks has not been thoroughly investigated. This study determined the acaricidal activity of A. indica and C. papaya leaf extract against R. sanguineus, both individually and … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 22 Apr 2025 · 8,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasurement of Gas-Phase Mass Transfer Coefficients in a Humidification Column through Random PackingMasoud Khorasani, Morteza Zivdar, Farshad Fashchi Tabrizi et al.Packed columns are an important part of the broad selection of mass and heat transfer equipment. Nowadays, the use of packed columns is increasing, which is because of its lower pressure drop, higher capacity and higher mass transfer in comparison to tray columns. The experiential tests and the hypothetical analysis display that the chemical dehumidification of air by hygroscopic salt … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Jul 2019 · 8,028 accessesView PDFCite
Review ArticleOpen accessIn the abstractNASA Data Used to Discover Eighth Planet Circling Distant StarRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuDiscovering the origins of life and colonizing extraterrestrial planets are two of the greatest ambitions that the international scientific community has today. Today, NASA is more prepared than ever to embark on an unprecedented race to conquer other worlds. The Kepler mission, named after Johannes Kepler, the German astronomer of the 16th-17th centuries, was scheduled to begin on March 7, … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 18 Jan 2018 · 7,904 accessesView PDFCite
Review ArticleOpen accessIn the abstractThere is Life on Mars?Relly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.If you can live on Mars, or if there was life on this planet, it's a natural question. The population of our planet has far outstripped the boundaries from which the planet begins to overcrow. Global resources are decreasing, while their consumption is rising more and more. The world's population is growing, it needs housing, food, water, air, clothes, transport, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 23 Dec 2017 · 8,575 accessesView PDFCite
Research ArticleOpen accessIn the abstractSilicone Modeling of the Interior Spaces of Hollow Organs: Use in Dog and Manatee Respiratory Tract and in a Beef HeartCharles J. Grossman, Richard Hamilton, Lisa A. Close-Jacob et al.Problem statement: The mechanism, by which the Florida manatee (Trichechus manatus latirostris) vocalizes, remains unknown because the manatee larynx does not contain true vocal cords. Since sound can be generated when air passes through a narrow respiratory structure we needed to visualize the internal anatomy of manatee respiratory tract to locate any candidate regions for study. Approach: To visualize the … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 7,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractOil Refineries Emissions Impact on Urban Localities Using AERMODAmira Mohamed Wahba Abdelrasoul, Amir AL-Hadad, Abdul Rehman KhanProblem statement: The absolute necessity of compulsory fuel utilities, no matter small or big has resulted into substantial high hazards pollutants. Petroleum refineries are major industrial installations that are necessary for providing the best suited fuel for various necessary utilities, but are responsible of the emission of several hazardous pollutants into the atmosphere. Hydrocarbons are among the most perilous air … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 7,729 accessesView PDFCite
Research ArticleOpen accessIn the abstractLaboratory Scale of Liquid Coal Fuel Combustion Process and Exhaust Gas FormationKartika Kus Hendratna, Osami Nishida, Hirotsugu Fujita, Wataru HaranoProblem statement: Much research of coal has been already undertaken to ascertain the possibilities of coal being used as substitute for heavy fuel oil in the transportation sector. The effects of using coal as transportation fuel to the environment must also be considered. This study will review several aspects of the coal oil combustion process including combustion behavior, flame stability, … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 6,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractReducing Ammonia Loss from Urea by Mixing with Humic and Fulvic Acids Isolated from CoalAmeera Abdul Reeza, Osumanu Haruna Ahmed, Nik Muhamad Nik Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization is a major pathway for nitrogen loss from surface applied urea. While all top-dressed ammonia and ammonium based N fertilizers can volatilize, the potential loss is greatest with urea and fluids containing urea. As much as 20-50% of N applied to soils is lost through volatilization alone. Thus, the objective of this laboratory study was to … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 10,897 accessesView PDFCite
