Canonical Diffeomorphisms of Manifolds Near Spheres by Wang, Bing, Zhao, Xinrui

“…Abstract For a given Riemannian manifold $$(M^n, g)$$ ( M n , g ) which is near standard sphere $$(S^n, g_{round})$$ ( S n , g round ) in the Gromov–Hausdorff topology and satisfies $$Rc \ge n-1$$ R c ≥ n - 1 , it is known by Cheeger–Colding theory that M is diffeomorphic to $$S^n$$ S n . …”

Shear behaviour of high-strength concrete beams by He, Lihua.

“…The rapidly increasing use of high strength concrete as an alternative to the more classical materials (normal strength concrete) requires knowledge by the design engineer of HSC behaviour in shear. The experimental investigation conducted in this project is important to evaluate the current design methods used for shear design of HSC beams, and the theoretical model proposed in this research for reinforced concrete element is capable of predicting not only the ultimate shear strength but also the load-deformation response of concrete elements subjected to in-plane shear and normal stresses.…”

Bio-based lubricant with additives: Tribological performances in hydrodynamic journal bearing by Norazman, Amanda, Paiman, Zulhanafi, Samion, Syahrullail, Afiq, Muhammad Noor, Muhammad Yazid, Witri, Rasep, Zuraidah

“…Purpose: The purpose of this paper is to investigate the performance of bio-based lubricants (BBL), namely, palm mid-olein (PMO) enriched with an antioxidant agent, tertiary-butylhydroquinone (TBHQ) and a viscosity improver, ethylene-vinyl acetate (EVA), in journal bearing (JB) applications. Design/methodology/approach: Samples of the BBL were prepared by blending it with TBHQ and EVA at various blending ratios. …”
