steel research international, EarlyView.High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

A multi-purpose method for analysis of spur gear tooth loading [PDF]
A large digitized approach was developed for the static and dynamic load analysis of spur gearing. An iterative procedure was used to calculate directly the "variable-variable" gear mesh stiffness as a function of transmitted load, gear tooth profile ...

New Directions for Student Leadership, Volume 2025, Issue 185, Page 107-113, Spring 2025.ABSTRACT Popular culture exists as an expression of cultural history. It speaks to who we are, what we aspire toward, and where our generation stands in relation to the major issues of the day. This article is a conversation about the myriad perspectives offered in this issue of New Directions for Student Leadership, exploring the contributions each ...

Journal of the Royal Anthropological Institute, EarlyView.While death remains a popular topic for anthropology, relatively few ethnographic accounts consider the modern bureaucratic processes accompanying it. One such process is public health autopsy, which scholars have largely taken for granted. Existing analysis has regarded it as a form of ‘cultural brokering’ and autopsy reluctance in communities is seen,

Generation of a crowned pinion tooth surface by a surface of revolution [PDF]
A method of generating crowned pinion tooth surfaces using a surface of revolution is developed. The crowned pinion meshes with a regular involute gear and has a prescribed parabolic type of transmission errors when the gears operate in the aligned mode.
