Research ArticleOpen accessIn the keywordsThe Effect of NaCl on the Stability of Ab3 Lipase from Sphingobacterium sp. that Co-Expressed with LEA K Using In silico ApproachIbrahim Muhammad et al.This study explores how sodium chloride (NaCl) influences the binding affinity and stability of the Ab3 lipase-LEA K complex when interacting with olive oil, using molecular docking techniques. The docking simulations, conducted with AutoDock Vina, reveal that the presence of NaCl significantly enhances the binding affinity of the enzyme-substrate complex, increasing it from-6.55 kcal/mol in the absence of salt to-7.81 … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 9 Mar 2025 · 5,599 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCircular Economy Modeling for Waste and Energy Management in A Developing Country: The Case of Greater Beirut AreaAbbas El Toufaili, Dario Pozzetto, Elio Padoano et al.Lebanon's energy system depends largely on imported fuels. Lebanon presented its commitment to increase by 30% its share of Renewable Energies (RE) by 2030. GBA lacks an integrated Municipal Solid Waste Management (MSWM) system. The waste composition in the Greater Beirut Area (GBA) is made of 52.2% organic waste which can be exploited for the production of green Hydrogen (H2) … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 22 Nov 2024 · 5,210 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPresenting a New Equation that Accurately Determines the Size of a Moving Elementary ParticleFlorian Ion Tiberiu PetrescuThe paper briefly presents a new Eq. (9). The role of Eq. (9) is to accurately determine the size of a moving elementary particle, depending on its velocity (or particle energy). Although Eq. (9) has a general character, it can be applied to any elementary particle in motion to determine the size of that particle, in the study, it was … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 24 Nov 2022 · 6,475 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInteraction between an Electron and a Quark DownRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuThe paper briefly studies the interaction between an electron and a down quark, considered integrated within a proton. It is therefore assumed that there is a down quark within a proton in which there are also two quarks up and an accelerated electron capable of penetrating the down quark inside the proton, in extremely difficult conditions in which the proton … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 6,954 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAbout Aircraft's New Power and PropulsionRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuEven though the current classical methods of aerospace propulsion are much improved, some of the most modern methods have already been introduced, including propulsion with electric motors. Energy can be obtained from hydrogen burners, honeycomb burners to protect the combustion of hydrogen that burns 10 times faster than conventional fuels or alcohols. Hydrogen storage is also done in honeycomb cell … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 5 Mar 2020 · 7,325 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFriendly Environmental TransportRelly Victoria V. Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThe shipments were absolutely necessary at all times, but still, have polluted and damaged the environment. Humanity is struggling between technological tests of deployment of new types of mild transport for the environment and the need to maintain still in the operation the machines already polluting products in large quantity, cheaper, more convenient economically, that customers have already been accustomed. … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 25 Jan 2018 · 8,010 accessesView PDFCite
Review ArticleOpen accessIn the keywordsStructure of Buried Ice on MarsRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuAfter the older evidence that there is carbon dioxide on Mars made up of oxygen 2 and carbon now we have evidence that there is even normal water on the marble consisting of hydrogen 2 and oxygen. In other words, we have Martian oxygen combined with carbon and hydrogen, so we can extract oxygen directly to the site to initially … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 22 Jan 2018 · 7,212 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTriton for Nuclear FusionRaffaella Aversa, Relly Victoria Petrescu, Antonio Apicella et al.In the nuclear fusion process that is permanently produced in the stars (suns) there is a thermonuclear reaction that uses as the main raw material the very first isotope of hydrogen, namely the Protium. This process is possible due to the huge temperatures and the unimaginably high pressures existing inside a star. At very high temperatures and pressures, matter begins … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 16 Dec 2017 · 8,917 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Quality of Transport and Environmental Protection, Part IRelly Victoria Virgil Petrescu, Aversa Raffaella, Samuel Kozaitis et al.The today main challenge to protect the environment through the development of new and more efficient transportation systems is presented. The absolutely necessary goods distribution and human transfers are polluting and damaging the environment and new solution should be envisaged; the conflicting strategies to adopt new types of environment friendly transportation while maintaining operative the more economically convenient, but largely … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 8 Sep 2017 · 7,812 accessesView PDFCite
InvestigationOpen accessIn the keywordsRecovered Gases and Bacteria from the Clostridium Genus as Ecological Condition Indicators of Bottom Sediments of the Eastern Donbass Small RiversRoman Gennad'yevich Trubnik, Yuriy Aleksandrovich Fedorov, Ludmila Anatol'yevna NedosekaThe results of determination of methane, total hydrogen sulfide and sulfite reducing clostridia in bottom sediments of small rivers and reservoirs of the Eastern Donbass are presented. The horizontal and vertical distribution of levels of reduced gases in bottom sediments is analyzed. The ecological condition of the bottom sediments was estimated by the clostridia titer and the methane index. The … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 27 Jul 2017 · 7,100 accessesView PDFCite
