INVESTIGATION OF GEARS WITH ASYMMETRIC PROFILE USING RELIABILITY PARAMETERS

Ukrainian Journal of Mechanical Engineering and Materials Science
The results of the study of gears with involute and sinusoidal teeth are presented herein. The subjects of the comparative analysis were the stresses at the root of the tooth from the side of the applied load and from the side of the unloaded profile, contact stresses, and elastic deformations under the action of a given torque.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...
