Research ArticleOpen accessEvery word in the titleLarge Eddy Simulation of an Ammonia JetM. Salinas-Vazquez, A. Espinosa, E. Barrios, W. VicenteA compressible jet flow of ammonia was studied through a series of Large Eddy Simulations. Simulations were focused in the zone where the inertial effects are much bigger than the gravitational ones. The ammonia jet is discharged into an air medium and the gases are treated as a two non-reactive ideal gas mixture. Different simulations were performed, going from the … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,743 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSensitive and Rapid Detection of Sulfate-Reducing Bacteria in Jet Fuel by Loop-Mediated Isothermal Amplification Combined with Lateral Flow DipstickZezhen Li, Yun Xiong, Peng Zhu, Hailong HuangThe existence of Sulfate-Reducing Bacteria (SRB) is one of the significant reasons for the Microbially Influenced Corrosion (MIC) of jet fuel. Especially for the jet fuel stored by military, since jet fuel is stored in the tank for a long time, some oxygen-consuming bacteria such as Amorphotheca resinae and Bacillus Cohn can consume oxygen and generate organic acids at the … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 11 Apr 2018 · 10,398 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfiltration of Nanoparticles into Porous Binder Jet Printed PartsAmelia Elliott, Sarah AlSalihi, Abbey L. Merriman, Mufeed M. BastiThe densification of parts that are produced by binder jetting Additive Manufacturing (AM; a.k.a. “3D Printing”) is an essential step in making them mechanically useful. Increasing the packing factor of the powder bed by incorporating nanoparticles into the binder has potential to alleviate the amount of shrinkage needed for full densification of binder jet parts. In this study we present … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 11 Mar 2016 · 13,401 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDEVELOPMENT OF A BACTERIAL CULTURE SYSTEM USING A PAPER PLATFORM TO ACCOMMODATE MEDIA AND AN INK-JET PRINTING TO DISPENSE BACTERIATithimanan Srimongkon, Takuya Ishida, Kiyohiko Igarashi, Toshiharu EnomaeGenerally, bacterial culture is performed manually and is subject to error. Here, we created a novel, well-ordered and reliable system for dispensing bacteria microscopically by using paper and an ink-jet printer for controlled patterning. For paper to accommodate a culture medium, hydrophobic/hydrophilic patterns were incorporated onto the paper by immersing paper in a toluene solution of polystyrene and drying for … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 26 Apr 2014 · 7,945 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAbrasive Jet Polishing and its Applications in Surface FinishingZhaoze Li, Jianmin Wang, Xiaoqiang Peng et al.Problem statement: Single Point Diamond Turning (SPDT) is highly deterministic and versatile in producing various forms of precise optics. A typical example is the production of large off-axis aspheric mirrors and various infrared mirrors and mandrels. However, the fine periodical turning marks left in the surface critically limit its performance and they are difficult to be avoided for traditional polishing … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 26 Jul 2011 · 13,592 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNucleation and Crystal Growth Rates of Struvite in DTM Type Crystallizer with a Jet-Pump of Descending Suspension Flow in a Mixing ChamberJoanna Koralewska, Krzysztof Piotrowski, Boguslawa Wierzbowska, Andrzej MatyniaThe kinetic data concerning reaction-crystallization of struvite from diluted water solutions of Mg2+, NH4+ and PO43- ions in a continuous DTM-type liquid jet-pump crystallizer with internal circulation of suspension are presented and discussed. The measurements were performed with the assumption of minimal value of unit power of a jet-pump’s feeding stream, providing thus a minimal level of internal circulation intensity. … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,958 accessesView PDFCite

Review ArticleOpen accessIn the keywordsNASA has Found the Most Distant Black HoleRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuScientists have uncovered a rare relic from the early universe: the farthest known supermassive black hole. This matter-eating beast is 800 million times the mass of our Sun, which is astonishingly large for its young age. Researchers report the find in the journal Nature. "This black hole grew far larger than we expected in only 690 million years after the … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 18 Jan 2018 · 7,298 accessesView PDFCite
Review ArticleOpen accessIn the keywordsModern Propulsions for Aerospace-A ReviewRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.A spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. There are several different methods, each with advantages and disadvantages, spacecraft propulsion being an active area of research. However, most current spacecraft are propelled by forcing a gas exits through the rear of the vehicle at high speed through supersonic nozzle of a rocket engine. All spacecraft … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 25 Apr 2017 · 12,889 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimized YOLOv8 for Insect Detection in Agricultural Farms Using Edge Vision SystemsDeebalakshmi R., Adhithyaa S., Yoga Vignesh V., Balaji Ganesh RajagopalFarmers started to adopt smart gadgets like automated pest detection and kiosks for their work in light of the AI revolution in agriculture.
