ABSTRACT Health messages can only improve health when audiences engage with them. Yet, receptivity to health messages is not uniform, and unequal engagement may contribute to health disparities. We approach these problems through the lens of interpersonal persuasion: health communication unfolds between message sources and recipients embedded in social,

Analysis of tribological processes at timing belt's tooth flank [PDF]
The paper presents basic tribomechanical systems in timing belt drives. Analysis of tribomechanical system belt's tooth - belt pulley's tooth, in which the largest value of friction force occurs, is conducted.

Study on Influence of Ultrasonic Vibration Lapping Gear on the Machining Quality of Tooth Flank
Two pairs of hypoid gears with 7/37 and 8/41 teeth are selected as experimental objects. The ultrasonic lapping of gear is carried out on the modified rolling inspection machine Y9550, ultrasonic vibration frequency is 16 kHz, ultrasonic grinding time is

Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

This study describes a new hexamerous epizoic brittle star species, Gymnolophus sexradia sp. nov., from the South China Sea, which lives on crinoid hosts and exhibits a six‐armed body plan possibly indicating fissiparity. Its vertebral and arm plate structures enhance horizontal flexibility for grasping the host, and phylogenetic analysis based on ...

ABSTRACT A new species of jewel beetle, Temognatha sundholmi Lang, sp. nov., is described from the Great Victoria Desert in South Australia. A broader investigation, using mtDNA COI ‘barcode’ sequences from 178 specimens representing 54 buprestid species, places the new species with Temognatha flavocincta (Gory & Laporte, 1838) in the informal ...
