Review ArticleOpen accessIn the abstractStudies on Environmental Impact Assessment of Reinforced Concrete in Different Life Cycle PhasesJair Frederico Santoro, Moacir KripkaConcrete is one of most used materials in construction and also one of the main responsible for the emission of carbon dioxide, or CO2, in the atmosphere. Thus, in order to study ways to reduce this impact, it is important to evaluate the influence of each raw material of the reinforced concrete, as well as the phases of the life … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 2 · 2 Jan 2018 · 8,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstrained Modified Genetic Algorithm for Optimizing RICE Climate Change Model PolicyHaitham OsmanThe objective of this paper is to use evolutionary algorithm for policy making to help in decision support, the Regional Integrated Climate-Economy (RICE) model for the dynamic climate change is used to optimize the tradeoff policy between abating of carbon dioxide emissions to reduce global climate change and in the other hand the resulting in economic damages. A Constrained Genetic … …American Journal of Applied Sciences, Vol. 14, Issue 10 · 12 Apr 2017 · 7,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Expediency of the Preliminary Heat Treatment for Liquid-Phase Reduction of Waste Steelmaking SlagEvgeny Trofimov, Ilya Chumanov, Andrey Dildin, Olga SamoylovaThe problem of using waste steelmaking slags as a technogenic source of metallurgical raw materials still has no sustainable solution and requires innovative ideas and approaches. The purpose of this paper is a theoretical and experimental study of the possibility and expediency of the preliminary heat treatment of steelmaking slags in a reducing medium for greater metal recovery. The subject … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 26 Nov 2015 · 7,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on CRDI System Assisted Diesel Engine Fulled by Diesel with NanotubesC. Syed Aalam, C.G. Saravanan, M. KannanThis paper reports on the use of carbon multiwalled nanotubes as additive to the diesel fuel and the effects of their operational characteristics and performance, emission and combustion characteristics of the CRDI system assisted diesel engine. In this study, the tested fuels were prepared by dispersing carbon multiwalled nanotubes into the diesel fuel at the mass fraction of 25 and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 17 Jun 2015 · 7,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractAIR POLLUTION AND CLIMATE CHANGE IN LAGOS, NIGERIA: NEEDS FOR PROACTIVE APPROACHES TO RISK MANAGEMENT AND ADAPTATIONAkinola A. Komolafe, Suleiman Abdul-Azeez Adegboyega, Adeleye Y.B. Anifowose et al.The significance of air pollution as one of the contemporary issues and accelerating factors that propel climate change in both developed and developing countries cannot be overemphasized. The problem of air pollution has seemingly become intractable with the incessant failure of both global and local environmental policies purportedly emplaced to address its devastating trend, particularly in growing megacities of the … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 12 Jul 2014 · 10,232 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrodeposition Fabrication of Pd Nanoparticles on Glassy Carbon Electrode Towards Methanol Oxidation ApplicationXiaoyun Qin, Wenbo Lu, Yonglan Luo et al.The present paper reports on the rapid fabrication of Pd nanoparticles on glassy carbon electrode by eletrodeposition technique. It suggests that such film exhibits good catalytic activity and stability with respect to methanol oxidation in an alkaline media. It also suggests that the loading of the Pd nanoparticles on the substrate and therefore the effective catalytic area can be tuned … …Current Research in Nanotechnology, Vol. 4, Issue 1 · 12 Apr 2013 · 11,333 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimizing of Trichoderma viride Cultivation in Submerged State FermentationHayyan Ismaeil Al-Taweil, Mohammad Bin Osman, Aidil Abdul Hamid, Wan Mohtar Wan YussofProblems statement: A study in Malaysia had shown a strain of Trichoderma viride was isolated from the soil. Questions were raised whether Trichoderma viride submerged state fermentation affected by parameters and which of them is effective? Approach: To investigate the effects of the submerged state fermentation parameters; concentrations of carbon g L-1; (10, 45 and 80), glucose, nitrogen g L-1; … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 10,076 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction of Essential Oil from Nigella sativa Using Supercritical Carbon Dioxide: Study of Antibacterial ActivityNagi A. Alhaj, Mariana N. Shamsudin, Hana F. Zamri, Rasedee AbdullahThe antimicrobial activity of N. sativa essential oil obtained by supercritical fluid extraction by carbon dioxide was investigated against Gram Positive and Gram negative strains, isolated from clinical specimens. Best conditions for Black cumin oil extraction are obtained at 400 bar, 40°C and a solvent flow rate of 25 g min-1. The seed extracts were prepared by supercritical fluid extraction … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 4 · 31 Dec 2008 · 8,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Modelling of an Industrial Smelter Furnace and Converter Off-gas SystemHelen Shang, Megan Dillabough, Phillip Nelson, Bryan SaltIn smelters, metal ores or concentrates are smelted to reduce a metal oxide to a metal through a series of reactions and processes. In a smelting process, a large amount of off-gas emissions are often generated, which can cause serious environmental and plant hygiene problems if not properly treated. Off-gas systems extract and treat the off-gas emissions, and ensure that … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,153 accessesView PDFCite
Review ArticleOpen accessIn the abstractProper Management of Planetary Hydrocarbon ResourcesFlorian Ion Tiberiu PetrescuMuch has been said about the planet's gas and oil resources and many assumptions and speculations have been made regarding their rapid depletion, but a report on the normal and judicious management of these important planetary resources for both energy and other various materials that are obtained today from them, such as composites, synthetic fibers for fabrics, plastics, rubber produced … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 24 May 2020 · 7,254 accessesView PDFCite
