Rotating Surfaces Promote the Shedding of Droplets
Research, 2023 Achieving rapid shedding of droplets from solid surfaces has received substantial attention because of its diverse applications. Previous studies have focused on minimizing contact times of liquid droplets interacting with stationary surfaces, yet little consideration has been given to that of moving surfaces.

Rotational surfaces in isotropic spaces satisfying weingarten conditions
Open Physics, 2016 In this paper, we study the rotational surfaces in the isotropic 3-space 𝕀3 satisfying Weingarten conditions in terms of the relative curvature K (analogue of the Gaussian curvature) and the isotropic mean curvature H.

Determination of power loss in compressor stage of turbogenerator in dynamic experiments [PDF]
Омский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение", 2018 A mathematical model for the interaction of a gas environment with the surfaces of the impeller of turbogenerator compressor is developed. The study of the characteristic of power losses at various rotational speeds of the rotor is provided ...

Novel piezoelectric crawling robot with multiple degrees of freedom
AIP Advances, 2021 Traditional ultrasonic motors can usually produce either linear or rotational motion. Piezoelectrically driven structures with multiple degrees of freedom require two or more ultrasonic motors, and the manufacturing process is associated with some ...

Kinematic surfaces with congruent generatrix curves
RUDN Journal of Engineering Research, 2023 Kinematic surfaces of general type are considered to include rotational, spiroidal and translation surfaces. The author indicates that a class of kinematic surfaces under consideration also comprises instances of eleven other classes. A classification of

On the duality between rotational minimal surfaces and maximal surfaces
Journal of Mathematical Analysis and Applications, 2018 We investigate the duality between minimal surfaces in Euclidean space and maximal surfaces in Lorentz-Minkowski space in the family of rotational surfaces. We study if the dual surfaces of two congruent rotational minimal (or maximal) surfaces are congruent. We show that in the duality process by means of a one-parameter group of rotations, it appears

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 ...
