Research ArticleOpen accessPhrase in the titleStatic and Dynamic Location of Variable Impedance Devices for Stability StudiesN. Magaji, M. W. Mustafa, Ado Dan-Isa, A. U. LawanThis study used the concept of model controllability and observability in product form called residue factor to find the best location of Thyristor-Controlled based series and shunt devices called variable impedance devices. The success of this controller depends on its best possible location in busbar or line of power system network. The method is based on the relationship between the … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 31 May 2013 · 6,625 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsUtilization of Charge Transfer and Kinetic Methods for the Determination of DoripenemNora H. Al-ShaalanProblem statement: This study presents rapid, uncomplicated and sensitive spectrophotometric techniques for the analysis of doripenem in both its pure and pharmaceutical forms. Approach: The main principle of the approaches and procedures that have been developed is the reaction of doripenem as an n-electron donor to ninhydrin and π-acceptors, such as tetracyanoethylene, 7,7,8,8-tetracyanoquinodimethane, 2,3,5,6-tetrachloro-1,4-benzoquinone, 2,3-dichloro-5,6-dicyano-1,4-benzoquinone and chloranilic acid. The wavelengths … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 10 Feb 2012 · 7,066 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInvestigation of the Contribution of Late Embryogenesis Abundant (LEA) K Peptide in Enhancing the Expression of Lipase from Sphingobacterium sp.: In vitro and in Silico StudiesIbrahim Muhammad et al.Sphingobacterium sp. AB3 lipase is a psychrophilic enzyme with optimal lipolytic activity at pH 7 and 15°C. The cold-adapted properties of the lipase render it suitable for various low-temperature industrial applications such as biodiesel production, detergent formulation, and non-thermal food processing. Recent studies have shown that co-expression of LEA K peptide with AB3 lipase resulted in enhanced protein expression in … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 21 Nov 2024 · 4,569 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhancing Drought Resistance in Spring Wheat (Triticum aestivum L.) Through Chelated Zinc Seed Treatment: An Experimental StudyBekzak Amantayev, Gulden Kipshakbayeva, Arysgul Turbekova et al.Climate change-induced drought is a significant threat to global food security, particularly affecting wheat yields. Despite various strategies to enhance drought resistance in crops, the effectiveness of chelated Zinc (Zn) as a seed treatment agent remains underexplored, especially in the early stages of wheat ontogenesis. This study aims to fill this gap by evaluating the effectiveness of zinc as a … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 26 Sep 2024 · 4,414 accessesView PDF Cite

Literature ReviewOpen accessIn the abstractLiterature Study on Factors Influencing the Biochemical Analytes Stability in Blood, Serum and Plasma: Systematic ReviewSamia El Mahi, Asmae Tantane, Sanaa Ait Hamou, Said OubraimBlood testing represents an essential phase in diagnosis and treatment. It is important to comprehend the biochemical analytes' stability. This research gathers information from different journals that have investigated the stability of biochemical analytes under different conditions. This research aims to collect and analyze data about conditions that promote stability, conditions that lead to instability, and how stability varies in … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 21 Aug 2024 · 5,192 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMechanism Analysis of Artemisinin and Artesunate as Lung Cancer Therapy Agents Through in Silico MethodDidik Harmoko, Vivitri Dewi Prasasty, Adi YulandiSeveral in vitro studies have focused on the ability of artemisinin and its derivatives to suppress lung cancer cells, but there are still many biological processes and mechanisms, such as the interactions between the active compounds (ligands) and receptors that are not well understood and require further research. Drug targeting for lung cancer will be more precise and the inhibition … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 15 Feb 2024 · 6,144 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of a Refrigeration System Based on Nano-Refrigerants and Nano-LubricantsHudaElslam A. S. Mohamed, Unal Camdali, Metin ActasMost of studies reported that disperse nanoparticles into refrigerants and lubricating oils lead to improve a coefficient of performance, due to improvement of thermal physics properties of a pure fluid, which leads to reduced energy consumption. Using nanoparticles in a refrigeration system is associated with many difficulties such as the cost of preparing and obtaining a stable and homogeneous mixture … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 12 Aug 2021 · 7,164 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIn vitro Antioxidant and Cytoprotective Potentials of Postbiotic ProbioMETA G55Xinyi Song, Ga Yeon Kim, Young Ki Lee, Jae Kyung KimStudies have demonstrated the favorable beneficial impact of probiotic metabolites on the skin. However, the use of postbiotics for skincare is a relatively new field despite their high safety and stability, which guarantee a longer shelf life.
