High speed miling in tool and die making [PDF]
, 2022 S.263 ffThe development of superabrasive cutting materials and highspeed motor spindles has led to further development of High Speed Milling in tool and die making. The main focus is generally on engineering developments (machine, tools, etc.), while the

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Effects of the Reynolds Number on the Efficiency and Stall Mechanisms in a Three-stage Axial Compressor [PDF]
Journal of Applied Fluid MechanicsThe Reynolds number (Re) is an important parameter that can affect compressor performance. This study experimentally and numerically investigated the effect of Re variations on the efficiency and stall mechanisms for a three-stage axial flow compressor ...

Numerical Study on Aerodynamic and Aeroacoustic Performances of Bioinspired Wings
Applied Bionics and Biomechanics, 2023 Noise control has become one of the key issues to be considered in modern aeronautical machinery design. Many efforts have been devoted to noise reduction of airfoils and wings, including traditional flow control methods.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

High speed rail: benefits that add up [PDF]
, 2012 This report argues that Australian could gain $48 billion of benefits from adopting high speed rail. High speed rail (“HSR”) now exists on every continent except for Australia and Antarctica.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
