Research ArticleOpen accessEvery word in the titleStudy of the Thermodynamic Equilibrium of Fragrance Mixtures, Limonene, Linalool and Geraniol, using the Unifac and Cosmo-Sac Models and the Estimation of their Combined Properties in Binary, Ternary and Quaternary MixturesLavínia Mota Cristianismo Silva, José Izaquiel Santos da Silva, Rogério Alexandre Alves de Melo, Edilailsa Januário de MeloPerfume is a non-ideal complex mixture of chemicals originating from the extraction of essential oils and these oils are volatile components extracted from plants, some animals, or even synthesized. For this reason, to compose a fragrance, there are countless possibilities to combine one element and another, which makes the process slow and expensive. Therefore, in this study, we will combine … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 2 · 14 Jun 2022 · 7,454 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePrice-Taking in General EquilibriumMurray C. KempThe Arrow-Debreu and McKenzie existence propositions of 1954 rest on the assumption of price-taking behaviour by households and firms. No attempt was made to justify the assumption or to relate it to other assumptions. It is here suggested that, given other assumptions common to the Arrow-Debreu and McKenzie models, price-taking implies that each household is incompletely informed and/or incompletely rational. … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 22 Dec 2005 · 7,717 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCoupling 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
Research ArticleOpen accessEvery word in the titleLinear General Equilibrium Model of Energy Demand and CO2 Emissions Generated By the Andalusian Productive SystemManuel Alejandro Cardenete, Patricia Fuentes Saguar, Clemente PoloIn this study we apply a multiplier decomposition methodology of a linear general equilibrium model based on the regional social accounting matrix to the Andalusian economy. The aim of this methodology is to separate the size of the different effects in terms of energy expenditure and total emissions generated by the whole productive system to satisfy the final demand of … …American Journal of Economics and Business Administration, Vol. 4, Issue 4 · 6 Jul 2013 · 7,079 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCarbon Dioxide Transfer with Chemical Equilibrium Reactions: An Alternative Mathematical ApproachA. ShanablehProblem statement: Despite intensive research efforts on CO2 transfer, mathematical models that describe the dependence of the CO2 transfer rate on the pH and the degree of rate enhancement due to CO2 chemical reactions remain unavailable. Approach: Such models are essential for assessing and accurately describing the progress of the CO2 transfer process. Results: In this study, an alternative view … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,040 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleArsenic Adsorption on Bauxite Mineral Using Batch Equilibrium TestFares Yahay Alshaebi, Wan Zuhairi Wan Yaacob, Abdul Rahim Samsudin, Esmail AlsabahiProblem statement: Study suggested a solution to remove arsenic contamination from contaminated water. Approach: Bauxite, which is a mineral, was proposed as natural remediation material used in this study. Bauxite was collected from Johor mining company in Teluk Ramunia, Johor Bharu, Malaysia. Batch equilibrium test was performed in accordance to different initial concentrations, shaking time and different initial pH values. … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 6,836 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEquilibrium Adsorption of Hydrogen and Methane on 5A Molecular SieveHayder A. Abdul Bari, Abdul Halim A.K. Mohammed, Abbas K.M. Shua'ab, Rosli Bin Mohd. YunusAdsorption equilibrium isotherms of hydrogen and methane are reported for the temperature range 303-333 K and pressure up to 4 MPa. The adsorbent was 5A molecular sieve (supplied by Rhone Poulenc industries Ltd.). Experimental data were obtained using a static system for gas-solid adsorption. The Langmuir adsorption equilibrium equation gave excellent predictions. Adsorption of hydrogen and methane on 5A molecular … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,389 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiosorption of Cr(III) by Microalgae and Macroalgae: Equilibrium of the ProcessIzabela Michalak, Agnieszka Zielinska, Katarzyna Chojnacka, Jan MatulaEquilibrium experiments of chromium(III) biosorption by microalga (Spirulina sp.) and macroalga (Pithophora varia) were investigated in this paper. Influence of the following process parameters was studied: pH, biomass concentration and temperature. The equilibrium of the process was described with Langmuir equation. The model parameters were determined at various process conditions. The best operation conditions for the process were selected: pH … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,204 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn the Stability of the Triangular Lagrangian Equilibrium Points in the Relativistic Restricted Three-Body ProblemM. K. Ahmed, F.A. Abd El-Salam, S.E. Abd El-BarThe restricted three body problem is treated in the framework of the post-Newtonian approximation of general relativity. The equations of motion are linear zed around the libration points L4,5. Locations of the equilibrium points L4,5 are obtained. Existence and stability of these points are investigated. The relativistic correction to the classical mass ratio is determined. …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 7,303 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBIFURCATION ANALYSIS OF EQUILIBRIUM POINT IN TWO NODE POWER SYSTEMHalima Aloui, Faouzi Bacha, Moncef GasmiThis study presents a study of bifurcation in a dynamic power system model. It becomes one of the major precautions for electricity suppliers and these systems must maintain a steady state in the neighborhood of the operating points. We study in this study the dynamic stability of two node power systems theory and the stability of limit cycles emerging from … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 29 Jan 2014 · 7,055 accessesView PDFCite
