Research ArticleOpen accessIn the abstractThermodynamic Inference of the Antioxidant Process of Malic Acid and Its Structural AnalogsHan Wu, Wenhao Dong et al.Two structural analogs of Malic Acid (MA), 2-isopropylmalic Acid (2-IPMA), and 3-isopropylmalic Acid (3-IPMA) were recently identified and separated from wine. Although they have been shown to have antioxidant activity, the mechanism of their actions is still unclear. Antioxidant activities of 2-IPMA and MA were tested through DPPH, ABTS, and PTIO methods and the antioxidant-related thermodynamic properties were evaluated using … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 30 Oct 2024 · 4,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Geobacillus thermodenitrificans Lipase Activity and Binding Affinity by Acetone Treatment: Kinetic and in silico InvestigationsAmmar Khazaal Kadhim Almansoori, Alyaa Abdulhussein Alsaedi et al.Lipase Geobacillus thermodenitrificans (LipGt) is a thermostable enzyme that has an optimal activity temperature of 65°C. It can tolerate various organic solvents and has an improved activity, especially in the presence of acetone. In this study, in-vitro and in-silico studies were carried out to investigate the effect of acetone in enhancing the kinetic and binding affinity of LipGt. The LipGt … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 10 Oct 2024 · 4,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractContributions to the Stirling Engine StudyFlorian Ion Tiberiu PetrescuIn the process of transforming thermal energy into mechanical work, among the known thermal machines, the Stirling engine is the one that can achieve the highest yield (theoretically up to the maximum yield of the Carnot cycle), although in practice it is reduced by the properties of gas and materials used such as friction coefficient, thermal conductivity, melting point, breaking … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 10,172 accessesView PDFCite
InvestigationOpen accessIn the abstractRegularities of the Oxidative Stress Processes in Case of Bleedings from Acute and Chronic Ulcers of the Stomach and DuodenumEkaterina Vladimirovna Silina, Mukimdjon Ahmadzhonovich Sobirovz, Sergey Brankovich Bolevich, Victor Aleksandrovich StupinThe main aim of the study was to determine ways of improving the results of treating patients with ulcer bleeding of various nature and severity. It was provided by the system study of free radical processes and evaluation of the effectiveness of timely antioxidant therapy. Material and methods. The study included 153 patients aged 18-94 years with acute and chronic … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 4 May 2018 · 7,416 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 abstractEffect of the Cresacin Feed Additive on the Digestibility of Nutrients, Productivity and Egg Quality in Egg Laying QuailsDjunaydi Gayirbegov, Gayaz EngurazovThe purpose of the article was to study the effect of the Cresacin feed additive on the digestibility and use of nutrients in the diet of egg laying quails, as well as their egg productivity and quality. The experiment was carried out on 600 heads of one-day-old quails of the Estonian breed, which were divided into four similar groups of … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 1 · 6 Mar 2023 · 5,284 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Approach to the Performance and Efficiency Power Analysis on Embedded Devices Using AsteriskAdauto Cavalcante Menezes, Toniclay Andrade Nogueira, Edward David Moreno Ordonez, Admilson de Ribamar Lima RibeiroVoice over IP (VoIP) communication will dominate the computing world for years to come. In order to perform VoIP communication, it is necessary to encode and decode the voice. This process consumes the main computational resources, as an example, it is possible to mention the processor and memory.

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 abstractDocking and Molecular Dynamics Simulations in Potential Drugs Discovery: An Application to Influenza Virus M2 ProteinMarine E. Bozdaganyan, Philipp S. Orekhov, Nicola L. Bragazzi et al.Molecular docking is a common method for searching new potential drugs. Improvement of the results of docking can be achieved by different ways-one of them is molecular dynamics simulations of protein-ligand complexes. As a model for our research we chose M2 membrane protein from influenza virus. M2 protein is a high selective tetrameric pH-gated proton channel. It was previously shown … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 11 Nov 2014 · 8,669 accessesView PDFCite
