Disc Tool Profiling for Air Compressor Screws with Complex Characteristic Curves
Journal of Machine Engineering, 2021 One of the best practical methods to machine the air compressor screw pairs is milling or grinding by disc tools. The mathematics involved in disc tool profiling is quite complex and requires representing the machined surface by mathematical equations ...

Mathematics gender gaps in Kenya: Are resource differentials between boys and girls to blame?
Cogent Education, 2018 The Blinder-Oaxaca approach has been used to decompose the gender gap in mathematics test scores in private and public primary schools in Kenya. That is, the mathematics production functions are estimated separately for boys and girls, the difference ...

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
