Research ArticleOpen accessEvery word in the titleOptimization of Ultrasonic-Assisted Total Flavonoids Extraction from Flower of Albizia Julibrissin Durazz. by Response Surface Methodology for Characterization of Chemical Profile and Evaluation of Antioxidant and Tyrosinase Inhibitory ActivitiesYijie Cheng, Yuwen Zhang, Hanzhang Sun et al.To investigate the flavonoids in flower of Albizia julibrissin (‘He Huan Hua’ in Chinese), the ultrasonic-assisted extraction of total flavonoids from ‘He Huan Hua’ was optimized by response surface methodology and the chemical profile was characterized by HPLC- QTOF-MS/MS. What’s more, the antioxidant and tyrosinase inhibitory activities of ‘He Huan Hua’ were also evaluated in this study. The extraction time, … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 14 Mar 2022 · 6,733 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA Study of Parameters Relationship to Backcutting Phenomena During High Speed End Milling of AISI H13Erry Yulian T. Adesta, Afifah Mohd Ali, Delvis Agusman et al.Problem statement: In die and mold industries, surface roughness of the dies and molds produced will determine the end product quality. Therefore, the desired finish surface was specified and the appropriate processes were selected to reach the required quality. Among many contributors to surface quality problem, backcutting is one of the factors influencing the surface roughness. Approach: The aim for … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,509 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEssential Oils from The Dropped Flowers of Camellia japonica: Extraction Optimization, Chemical Profile and Antibacterial PropertyYunqi Kong, Gaochao Wang, Xinyu Wang et al.Camellia japonica is one of the most economically valuable species that can be taxonomically placed in the Theaceae family. Many horticultural varieties of C. japonica have been cultivated as ornamental trees worldwide, owing to their charming flowers. However, young C. japonica flowers usually drop in a “decapitated” form during the peak flowering stage, causing a resource waste. In this study, … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 27 Jan 2021 · 6,985 accessesView PDF Cite

Research ArticleOpen accessIn the abstractXPS Studies of the SiO2 Substrates and Thermoelectric Thin Films of Sn/Sn+SnO2 under the Effects of the Different Thermal TreatmentsRichard Lagle, Stephen Egarievwe, Satilmis Budak, Mebougna DraboMultilayered thermoelectric Sn/Sn+SnO2 thin films were prepared using KJL DC/RF magnetron sputtering system under Ar gas plasma on the SiO2 substrates. The thicknesses of the fabricated thin films were found using Filmetrics UV thickness measurement system. The fabricated thin films were annealed at different temperatures for one hour to tailor the thermoelectric properties. In this study, unannealed, annealed at 150 … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 8,209 accessesView PDF Cite

Review ArticleOpen accessIn the abstractCardiolipin in Pathology: Implications in AtherosclerosisAnastasia Vladimirovna Poznyak, Vasily Nikolaevich Sukhorukov, Anton Yuvenalievich Postnov et al.Mitochondria are cell organelles whose main role is to generate the energy needed for cell biochemical reactions via oxidative phosphorylation. Cardiolipin is a phospholipid that is present in the inner mitochondrial membrane and other energy-transducing membranes. Mitochondrial structure largely depends on cardiolipin, as it is involved in the biogenesis of mitochondrial cristae, folds in the inner mitochondrial membrane designed to … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 23 Sep 2023 · 4,792 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSoil Organic Carbon Pool and its Storage in Arial Beel Wetland Soils of BangladeshMd. Faruque Hossain, ASM Maksud Kamal, Monera Akhter Eva et al.The actual quantity of Soil Organic Carbon (SOC) stored in wetlands can only be estimated within a broad range of uncertainty. An accurate assessment of the size and distribution of the SOC storages in wetland resources is very difficult to obtain, therefore, the proposed research objective is to measure SOC storage and its pool on wetland soils of Arial beel … …American Journal of Environmental Sciences, Vol. 16, Issue 3 · 17 Aug 2020 · 7,382 accessesView PDF Cite
