Research ArticleOpen accessIn the keywordsModeling and Performance Analysis of a Petroleum-Pipeline-Pressure-Boosting Station Powered by Two-Shaft GT EngineYousef S. H. Najjar, Mohammad Z. M. Yousef, Aad M. A. Al-MahgariThis study offers modeling and performance analysis of a pressure-boosting station for petroleum pipelines using a sustainable two-shaft GT engine to drive a three-stage centrifugal pump. The modeling is divided into three steps; matching the GT engine components at the maximum efficiency line, matching the pump performance with the requirements of the pipeline system to generate the pump load curve, … …Energy Research Journal, Vol. 12, Issue 1 · 18 Jan 2022 · 10,510 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCoupling Analysis of Thermodynamic Equilibrium of Mass Transfer and Microbial Community Succession in Multiphase System of Dark Tea Solid-State FermentationZhanjun Liu, Jiawei Sun, Taotao Li et al.During the solid-state fermentation of dark tea, the limited material migration, the dynamic evolution of the thermodynamic equilibrium state, and the highly dynamic succession of the microbial community make it difficult to analyze the quality formation mechanism systematically. Traditional research has focused on microbial diversity or sensory quality analysis, lacking a systematic discussion on the regulatory effects of material migration … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 10 Aug 2026 · 1,004 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNitric Oxide Treatment Improves the Antioxidant Capacity While Inhibiting Anthocyanin Biosynthesis of Peach Fruit (‘Xiahui-8’) During RipeningZiqi Wang, Yanyan Li, Yingling Deng et al.Nitric Oxide (NO) is an important bioactive signal molecule that plays an important role in diverse physiological processes. This study aimed to explore the effects of Nitric Oxide (NO) treatments on postharvest peach fruit. Specifically, we examined changes in quality attributes, antioxidant ability, and anthocyanin profiles during storage, given the important role of NO as a bioactive signal molecule in … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 14 Apr 2026 · 1,392 accessesView PDF Cite
