Research ArticleOpen accessEvery word in the titleStructural Integrity Assessment of High-Pressure Vessels for Hydrogen Storage Using Finite Element AnalysisPinar Mert Cuce, Erdem Cuce et al.Hydrogen is not only present in the structure of most substances but also attracts attention as a clean energy source. The fact that hydrogen only releases water through combustion and possesses high energy potential provides a significant advantage as an alternative energy source. This paper presents a numerical investigation into the stress and deformation behaviour of high-pressure vessels used in … …Energy Research Journal, Vol. 15, Issue 1 · 13 Jun 2026 · 1,498 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects Of Ultra-High Pressure and Thermal Treatment on Quality Characteristics of Prepared Mackerel Fish BallsBiaoshi Wang, Xiaojun Hu, Jingqiu Ma, Ying XuSafe and high-quality prepared foods are increasingly preferred by consumers. This study investigates how ultra-high pressure (UHP) and thermal treatment affect the quality characteristics of prepared mackerel fish balls for surimi product manufacturing. Prepared mackerel fish balls were subjected to UHP treatment at 250 or 350 MPa (10 min) and thermal processing (121°C for 13 or 15 min) to establish … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 6 Jan 2026 · 2,237 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Ultra-High-Pressure Treatment on the Chemical Composition and Aroma of Flue-Cured Tobacco Leaves for Heated Tobacco ProductsXinbo Lu, Jie Yin, Ying Yuan et al.The influences of different Ultra-High-Pressure (UHP) treatments on the chemical composition and the low-temperature pyrolysis products of Flue Cured Tobacco Leaves (FCTL) that applied in heated tobacco products were investigated in this study. Results indicated that UHP treatment reduced total alkaloids content significantly (p<0.05), especially 500-600 MPa treatment group (2.34±0.00%, 2.34±0.01%). Increase in sugars and potassium content were observed after … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 19 Oct 2025 · 2,150 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Investigation of Mold Cavity Pressure of Self-Clamping Molds During Solid Tire ManufacturingSadeep Amantha Mawathage, Jayashingha Arachchige Indika Sanjeewa, Nirosh Dilruk JayaweeraThis study investigates the mold cavity pressure in self-clamping molds used for solid tire manufacturing, a sector where Sri Lanka is a leading global supplier. Our research presents a detailed investigation into the mold cavity pressure of self-clamping molds used in solid tire production. By integrating experimental data, the effects of critical parameters such as clamp bolt torque, final tire … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 2 Oct 2025 · 2,963 accessesView PDFCite
Case ReportOpen accessEvery word in the titleUtilization of a Pressure Cooker for Homemade High-Temperature Sterilization of RendangDaimon Syukri, Rini, Risa Meutia Fiana et al.This study aimed to analyze the impact of pressure cooker (presto) sterilization on the nutritional value and microbial content of rendang, a traditional Indonesian meat dish. The evaluated parameters included moisture content, ash content, fat content, protein content, and total plate count (TPC), measured before and after a 40-minute sterilization process. The results showed a moderate increase in moisture (from … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 28 Jun 2025 · 3,264 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModeling 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 PDFCite
