Research ArticleOpen accessEvery word in the titleRational Mix Design Approach for High Strength Concrete Using Sand with very High Fineness ModulusKwan Wai Hoe, Mahyuddin RamliProblem statement: Production of concrete is always deal with inconsistency. Sources of variation like materials from different geographical basis, mix design method, fineness of aggregates and so on will attribute to different level of achievement of the concrete. Even though researcher had verified that higher fineness modulus of sand would yield better performance for the concrete, but so far there … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 8,217 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign, 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 accessEvery word in the titleIncreasing the Strength of Standard Involute Gear Teeth with Novel Circular Root Fillet DesignV. Spitas, Th. Costopoulos, C. SpitasIn this study the idea of spur gear teeth with circular instead of the standard trochoidal root fillet is introduced and investigated numerically using BEM. The strength of these new teeth is studied in comparison with the standard design by discretizing the tooth boundary using isoparametric Boundary Elements. In order to facilitate the analysis the teeth are treated as non-dimensional … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,586 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGlass Strength for Impact and Blast LoadingMatthias Förch, Frank WellershoffGlass strength is highly influenced by strain rate. This material behaviour is well known in structural glass design and implemented in various standards. The strength of architectural glass is determined by component tests with a defined strain rate of 2 N/(mm2s), providing favourable terms for testing. As typical effects of actions on facades result in lower or higher strain rates, … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 7 May 2021 · 8,115 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHigh Rate-Dependent Interaction Diagrams for Reinforced Concrete ColumnsTaher Abu-Lebdeh, Sameer Hamoush, Wonchang Choi, Moayyad Al NasraProblem statement: There is a need to better understand the rate dependence behavior of reinforced concrete structures in order to improve their response to impact and blast loads. Analysis and design of reinforced concrete structures subjected to seismic loadings has been recommended in many FEMA guidelines. However, reevaluation of design becomes extremely important in cases where large deformations are expected … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 27 Jan 2011 · 8,020 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparative Assessment of Analytical models for the ULS Resistance Verification of Structural Glass Elements under Variable LoadsChiara Bedon, Claudio AmadioThe design of glass structures, due to the intrinsic material properties, is mainly governed by the typical tensile brittle behavior of the material. In this regard, a currently open question related to the use of glass in buildings as a load-bearing constructional material, is represented by the correct estimation of static fatigue phenomena due to a generic combination of design … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 16 Mar 2017 · 7,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractCulture and Religion Meaning-Making Coping Strategies in Wartime: Insights from a Qualitative Study on the Coping Experiences of UkrainiansFereshteh Ahmadi, Nataliia Melnyk et al.This study explores how Ukrainians use religious and spiritual meaning-making coping strategies during the ongoing war, shaped by cultural traditions, historical experiences, and personal circumstances. Its aim is to deepen understanding of culturally relevant resilience mechanisms in extreme adversity. Using a qualitative design, 67 semi-structured interviews were conducted across diverse Ukrainian regions between January 2024 and June 2025. Participants varied … …Journal of Social Sciences, Vol. 22, Issue 1 · 8 May 2026 · 2,435 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Polyester Grouted Connector for Splicing of Reinforcement BarsAshraf Fadiel, Nuria Mohammed, Ahmad Baharuddin Abdul Rahman et al.The research aims to investigate the viability of employing polyester grout as a bonding agent for the splicing of reinforcement bars. 0.43 and 1 binder-to-filler ratio were examined. The process of splicing reinforcement bars under tension using a polyester grouted splice connector is elucidated. Through direct tension tests, the optimal mix design and required length of the splicing sleeve were … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 1 · 16 Feb 2024 · 4,688 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Rosemary Collagen Chitosan Blend Membrane Using Response Surface Methodology (RSM)Ming He, Yuhan Zhai, Yuqing Zhang et al.The present research provided a formula for the optimization of rosemary/collagen/chitosan blend membrane. Rosemary Extract (RE) was used as additive and membrane was prepared using tensile strength, elongation at break and elongation length as the indexes. The results of single factor experiment showed that the addition ratio of collagen to chitosan, additive content, glycerol content and drying temperature all affected … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 22 Nov 2021 · 6,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Bisphenol A Polyether Polyols on the Synthesis of Hydrophilic Epoxy ResinsJinhua Yi, Xin YuanThe article uses three types of Bisphenol A polyether polyols BEO, BPO-6 and BPO-10 as raw materials, reacts with epichlorohydrin under the action of a catalyst and synthesizes a hydrophilic epoxy resin. The molecular structure of the product is analyzed by infrared spectroscopy and the results show that the synthesis of the hydrophilic epoxy resin BEOGE conforms to the results … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 3 · 15 Jul 2021 · 7,659 accessesView PDFCite
