Costopoulos, Andonios D. TsolakisProblem statement: In this study a comprehensive methodology for calculating load sharing in Roller-bearing contact was presented based on the experimental stress-optical method of caustics and Photoelasticity. Approach: The theoretical equations describing the geometry of transmitted caustic in relation to the length of the contact zone were derived and a simple mathematical set of equations correlating the maximum diameter of … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,397 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransverse Velocity, Transverse Boundary Shear Stress and Flow Deviation in Meandering Open ChannelsYoussef Ismail HafezThis study presents a novel approach for characterizing the mechanics of flow in mildly meandering open channels, specifically focusing on the development of a new vertical distribution equation for transverse velocity. Unlike existing equations in the literature that rely on complex logarithmic or integral forms or infinite series forms, which are impractical for hydraulic engineers, the proposed equation employs ordinary … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 25 Jul 2024 · 5,058 accessesView PDFCite
Literature ReviewOpen accessIn the abstractMolecular Genetic Basis of Starch Biosynthesis and Waxy Allelic Variation in Rice Grain QualityInnabat Sartbayeva, Aigul Amirova, Dana Mynbaeva et al.The culinary, nutritional, and industrial properties of rice (Oryza sativa L.) grains are fundamentally governed by the structural arrangement of endosperm starch, a complex physiological phenotype shaped by genetic architecture and environmental conditions. This review provides a comprehensive synthesis of the molecular pathways driving starch biosynthesis in rice, centering on allelic diversity within the Waxy (Wx) locus, which codes for … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 22 Sep 2026 · 479 accessesView PDFCite
Research ArticleOpen accessIn the abstractExamination of Laminated Glass with Stiff Interlayers – Numerical and Experimental ResearchJulian Hänig, Paulina Bukieda, Michael Engelmann et al.Glass is a linear-elastic and isotropic building material which allows for a quick calculation of internal forces and stress in the design stage. However, in safety applications, e.g. overhead glazing or balustrades, it is made into laminated glass using plastic interlayers. Their material properties change over time and are temperature-dependent. Additionally, larger spans and the demand to reduce the amount … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 25 Jan 2019 · 13,559 accessesView PDFCite
EditorialOpen accessIn the abstractVisceral Pain: Basic Research Concepts and Therapeutic InterventionsVictor V. ChabanThe accumulation of nociceptive diseases that limit normal body functions is a major risk factor for a disability, and visceral pain is one of the most prevalent human health problems. Additionally, many pain-associated diseases are accompanied by the concomitant decline in cognitive and motor performance. The complex interplay and balance between diverse signal transduction mediators, genetic background and environmental factors … …International Journal of Research in Nursing, Vol. 6, Issue 2 · 26 Aug 2015 · 7,148 accessesView PDFCite
