Research ArticleOpen accessIn the abstractApplication and Prospect of CO2 Enrichment Technology in AgricultureBingbing Wang, Xiangjie Lu, Wanlin Gao et al.With the increasing consumption of fossil fuels for human activities, the emissions of greenhouse gases, such as CO2, have significantly increased, resulting in an intensified greenhouse effect. As an important element for plant photosynthesis, CO2 enrichment in an appropriate environment can promote photosynthetic rate, organic matter accumulation and the growth rate of plants. The CO2 enrichment technology should be widely … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 10 Feb 2022 · 6,454 accessesView PDFCite
Review ArticleOpen accessIn the abstractNuclear Reactors, their Types and Impact on Safety, Environment and Sustainability towards a Green FutureAyush Kumar A, Godwin Glivin, N. Kalaiselvan, V. MariappanThe current world is shifting rapidly towards clean energy sources due to the rapid depletion of fossil fuels. Also, as a solution to the extremely intense growing demand of energy across most of the countries and increasing pollution, nuclear energy is considered as a strategic alternative as it is both clean and does not pollute the environment. When compared with … …Energy Research Journal, Vol. 11, Issue 1 · 29 Oct 2020 · 6,969 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Validation of a Mathematical Model of the Operation of a Hydraulic Ram Pump with a Springs SystemAndriamahefasoa Rajaonison, Hery Tiana RakotondramiaranaWater pumps, which usually require fuels or power, are for carrying water from water sources to a facility, generally a household or a farm in the countryside. The present study consists of conducting an experimental validation of a mathematical model that was developed in a previous work for simulating the functioning of a new form of the hydraulic ram pump, … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 14 Jun 2020 · 7,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Cobalt, Iron and Ruthenium Catalysts for the Production of Synthetic DieselDayna M. Ortiz Rodríguez, María del C. Cotto-Maldonado, José Duconge Hernández et al.Fossil fuels are currently the world's leading source of energy. Environmental legislations, the high price of fossil fuels, the concern about the supply of these fuels and technological development, makes it necessary to search for alternative sources of energy. The production of clean liquid fuels, such as synthetic diesel from synthesis gas, by Fischer-Tropsch (FT) method, is considered a very … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 29 Apr 2020 · 7,248 accessesView PDFCite
Review ArticleOpen accessIn the abstractAbout the Space RobotsRelly Victoria Virgil PetrescuToday, robots help us more than ever in all major operations, everyday life and become a daily reality, making it an integral part of major human projects. If they are still the majority in the machine industry, they will soon become as many in other industries and at the same time will grow strongly for human support in conquering extraterrestrial … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 25 May 2019 · 6,962 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersonal Exposure to PM2.5 in the Various Microenvironments as a Traveler in the Southeast Asian CountriesSemih Ozler, Karoline K. Johnson, Michael H. Bergin, James Jay SchauerAir pollution has become a pressing issue in today’s society because of its significant effects on humans, animals, plants, air quality, climate and the wider environment. Most urban areas are associated with one or more air pollutants which are emitted from local or regional pollution sources including vehicle exhausts, fossil fuels using in energy production, emissions from industrial and mining … …American Journal of Environmental Sciences, Vol. 14, Issue 4 · 27 Oct 2018 · 9,274 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovements on Semi Critical Assisted-Solvent Extraction of Biocrude Oil from Spirogyra. sp Macro AlgaeTulio Chavez-Gil, Hany F. Sobhi, Alexis Pacheco-LaracuenteHere, we report on an improved chemical method to extract hydrocarbons (CH) and Fatty Acid Methyl Esters (FAME) from wild green macro algae, which is higher than that carried out with conventional Soxhlet (Sx) and similar to that of Subcritical (SbC) or supercritical fluid (SCE) extraction methods. Crude oil plus residual biomass gave combined calorific values of 49.05 MJ/kg in … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 18 Apr 2018 · 10,083 accessesView PDFCite
Review ArticleOpen accessIn the abstractConversion of Carbon Dioxide: Opportunities and Fundamental ChallengesSajeda A. Al-Saydeh, Syed J. Zaidi, Muftah H. El-NaasThe rising atmospheric levels of carbon dioxide is one of the most urgent challenges facing societies nowadays. There is also great potential in energy carriers and other materials from CO2, with many challenges to overcome. The way to reduce greenhouse gas emissions should be using carbon free sources that do not generate carbon dioxide to the atmosphere. This article reviews … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 17 Jan 2018 · 7,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Planning and Design of an Environmentally Friendly Hybrid Energy System for Rural Electrification in IraqAli Saleh Aziz, Sara Ahmed KhudhierCurrent power systems create environmental effects because of the using of fossil fuels, specially coal, since CO2 is released to the atmosphere. Contrary to conventional energy sources, renewable energy sources produce a clean energy which is in general free of pollution, environmentally sustainable and technologically efficient. There is an increased interest in solar energy that can generate electricity with no … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractCFD-PBE Modelling and Simulation of Enzymatic Hydrolysis of Cellulose in a Stirred TankNorazaliza Mohd Jamil, Qi WangRenewable energy or biofuel from lignocellulosic biomass is an alternative way to replace the depleting fossil fuels. The production cost can be reduced by increasing the concentration of biomass particles. However, lignocellulosic biomass is a suspension of natural fibres and processing at high solid concentration is a challenging task because it will affect the mixing quality between the enzyme and … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 25 Oct 2016 · 7,999 accessesView PDFCite
