Abstract Flow forming and inertia friction welding (IFW) have been widely used as manufacturing processes that produce high-value engineering components. Combining these two advanced facilitates the fabrication of near-net shape components leading to optimized designs. This study introduces joining flow-formed seamless tubes MLX®19 maraging steel using IFW process fabricate a component in landi...
Background: Enhancing the industrial yeast strains ethyl acetate yield through a precise and seamless genetic manipulation strategy without any extraneous DNA sequences is an essential requisite and significant demand. Objectives: For increasing the ethyl acetate yield of industrial brewer’s yeast strain, all the ATF1 alleles were overexpressed t...
the brass tubes with foam cores of alsi7sic3, alsi7sic3fe1 and alsi7sic3fe3 were produced as the crush-boxes with circle and square cross-section. then axial compressive behavior and energy absorption capability of the foam-filled tubes were investigated during the quasi-static progressive plastic buckling. the uniaxial compressive stress–strain curves of the foam-filled brass tubes exhibited t...

background: establishment of viable pregnancy requires embryo implantation and placentation. ectopic pregnancy (ep) is a pregnancy complication which occurs when an embryo implants outside of the uterine cavity, most often in a fallopian tube. on the other hand, an important aspect of successful implantation is angiogenesis. vascular endothelial growth factor (vegf) is a potent angiogenic facto...
