Research ArticleOpen accessIn the keywordsINVESTIGATION STUDIES ON SUB-COOLING OF CRYOGENIC LIQUIDS USING HELIUM INJECTION METHODT. Ramesh, K. ThyagarajanIn cryogenic propellants, the sub-cooling of cryogenic propellants contained in tanks is an important and effective method for bringing down the lift-off mass of launch vehicle and thus the performance of the rocket engine is greatly improved. This study presents the technical and experimental studies conducted on cryogenic liquids such as Liquid Oxygen, Liquid Nitrogen and Liquid Hydrogen using helium … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 10 Feb 2014 · 6,801 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance Evaluation of an Oxidation Ditch System with a Disc AeratorAbdel Ghaly, Ashley ThistleProblem statement: The oxidation ditch system has been used to treat various types of wastewaters. Several types of aerators are used to supply the treatment process with oxygen. Among these devices, the disc aerator has certain advantages regarding foam generation over the brush and paddle type rotors, but the main disadvantages of this aerator is the limited oxygenation capacity. The … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 8,113 accessesView PDFCite
Research ArticleOpen accessIn the keywordsVitamin E and Beta Carotene Composition in Four Different Vegetable OilsAb. Gapor Md. Top, Halimah Muhamad, Aminah Abdullah et al.Problem statement: Some vegetable oils contains natural antioxidants such as beta carotene and vitamin E namely tocopherol and tocotrienol. Different vegetable oils contained different amount of vitamin E and β-carotene. Approach: Study was carried out to investigate the natural antioxidants (vitamin E and beta carotene) composition in four different vegetable oils [Red Palm Olein (RPO), palm plein (PO), Corn Oil … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 9,316 accessesView PDFCite
Research ArticleOpen accessIn the abstractCoupling Analysis of Thermodynamic Equilibrium of Mass Transfer and Microbial Community Succession in Multiphase System of Dark Tea Solid-State FermentationZhanjun Liu, Jiawei Sun, Taotao Li et al.During the solid-state fermentation of dark tea, the limited material migration, the dynamic evolution of the thermodynamic equilibrium state, and the highly dynamic succession of the microbial community make it difficult to analyze the quality formation mechanism systematically. Traditional research has focused on microbial diversity or sensory quality analysis, lacking a systematic discussion on the regulatory effects of material migration … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 10 Aug 2026 · 1,004 accessesView PDFCite
Review ArticleOpen accessIn the abstractMars Could have Enough Molecular Oxygen to Support LifeRelly Victoria Virgil PetrescuThere is a recently introduced study that proposes the idea of the possibility of salty water somewhere on the surface of the planet Mars or immediately near the surface but in the basement of the planet at a relatively small depth. The study illustrates the possibility of O2 oxygen dissolved in salt water, oxygen needed to support breathing oxygen, microbes … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 28 Feb 2019 · 7,730 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.

Research ArticleOpen accessIn the abstractLaser-Induced Breakdown and Detonation in Particle-Laden SystemsKonstantin VolkovSimulation of the interaction of a laser pulse with gas-droplet and gas-particle mixtures plays an important role in environmental and engineering applications. The injection of liquid droplets or metal particle causes optical breakdown on the individual droplet or particle and leads to a drop of the detonation minimum pulse energy of the mixture. Mathematical models of various stages of the … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 4 Mar 2015 · 7,348 accessesView PDFCite

Research ArticleOpen accessIn the abstractOptical Investigation and Electronic Polarizability of Nd3+ Doped Soda-Lime-Silicate GlassesP. Chimalawong, J. Kaewkhao, P. LimsuwanProblem statement: This study researched on different physical and optical properties of Nd3+ doped soda-lime-silicate glass. The glasses containing Nd3+ in (65-x)SiO2: 25Na2O: 10CaO: xNd2O3 (where x = 0.0-5.0 mol%) had been prepared by melt-quenching method. The density and molar volume increase with increasing of Nd2O3 concentration due to increasing of Non Bridging Oxygen (NBOs) in glass matrix. The optical … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,149 accessesView PDFCite
