Research ArticleOpen accessPhrase in the titleThe Influence of Foam Density on Specific Energy Absorption of Rectangular Steel TubesNirut Onsalung, Chawalit Thinvongpituk, Kulachate PainthongProblem statement: In general, the automotive structure is targeted to absorb high impact energy with least mass as much as possible. This is in order to limit the fuel consumption. Therefore, various techniques to increase the energy absorption with less mass increment have been studied for years. One of those techniques is by filling foam in the tube. This study … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,440 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThermodynamic Analysis of an Absorption/Compression Refrigeration System Using Geothermal EnergyL. Kairouani, E. NehdiThis article presents the potential use and exploration of geothermal energy for cooling applications using a combined absorption/compression system. The considered system uses R134a for the compression part and the cool water-ammonia for the absorption part of the installation. The geothermal temperature source is in the range 343-349K, the condensation temperature is 308 K, and in order to produce ice, … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,554 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of a Phytomineral Complex and an Enzyme Preparation on the Absorption of Nutrients and the Energy Balance of Calves' DietEvgeniia Erenko, Aleksandr Ovchinnikov, Marat Aubakirov et al.Cost-effective animal husbandry directly depends on the correct breeding of replacement young animals using diets corresponding to the feeding rate for all nutrition elements of the detailed system. Critical to these diets are biogenic elements, pivotal in enzymatic reactions and immune defense. However, specifics on enhancing nutrient absorption through dietary supplements remain underexplored, particularly in the context of calves' preweaning … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 12 Jun 2024 · 4,592 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign, Development and Numerical Analysis of Honeycomb Core with Variable Crushing StrengthShabnam Sadeghi Esfahlani, Hassan Shirvani, Ayoub Shirvani et al.A honeycomb core with half-circular cut-away sections at the spine (the adjoining cell walls) is designed and developed and numerically tested under axial dynamic load condition. The parametric study is invoked to identify the effect of various circular cut-away dimensions. In one embodiment a half-circular shaped cuts are removed from the top of the cell where the cell is impacted … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 15 Jan 2013 · 7,572 accessesView PDFCite

Research ArticleOpen accessIn the abstractVirtual Screening of Bioactive Compounds from the Onion (Allium) Genus as Potential Epidermal Growth Factor Receptor Inhibitors for MonkeypoxDinda Ratu Agustiani, Rakhmat Ramdhani Alwie, Harry NoviardiMonkeypox (Mpox) is an emerging zoonotic disease caused by the Mpox virus infection that affects humans and animals. Epidermal Growth Factor Receptor (EGFR) is an important target in the pathogenesis of Mpox. Epidermal Growth Factor (EGF), encoded by orthopoxviruses, plays an important role in intercellular transmission of the virus. Onion is known to have antiviral and immunomodulatory properties. Active compounds … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 6 Aug 2026 · 945 accessesView PDFCite
