When Do Citizens Support Corrupt Politicians? The Trade‐Offs Between Corruption and Competence
ABSTRACT The intriguing paradox of wide public disdain for corruption alongside popular corrupt politicians exists globally. By speaking to public ethics theory and rational choice theory, this study examines the trade‐off in which citizens tolerate corrupt officials in exchange for their competence to deliver public benefits.

Abstract Purpose To describe the use of coronofrontal rhytidectomy (CFR) for the treatment of severe pseudoptosis and superior entropion in dogs, and to provide guidelines for the selection of surgical technique depending on presentation. Methods A review of medical records of dogs that underwent rhytidectomy from 2002 to 2023 was carried out ...

Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

A Theory of Lubrication by Microirregularities
Journal of Basic Engineering, 1966This paper describes a theory of liquid lubrication applicable to parallel surfaces, such as the surfaces of a rotary-shaft face seal. The lubrication mechanism presented is based on surface microirregularities and associated film cavities. Closed-form analytical solutions are obtained giving load capacity as a function of speed, viscosity, and surface-

On the granular lubrication theory
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005The governing equations for the flow of a granular material within the context of the lubrication theory are derived. The resulting analysis gives a generalized Reynolds equation that predicts the pressure generation capacity in a bearing with consideration of side flow. A series of simulations are presented that characterize the three-dimensional flow

Magnetohydrodynamic Theory of Lubrication
The Physics of Fluids, 1962The magnetohydrodynamic theory of the two-dimensional flow between plane walls of small inclination is applied to the problem of lubrication of bearings. Equations are given for boundary conditions. The arrangement of guide surface and slide block in relation to the external magnetic field are shown.

Lubrication Theory for Micropolar Fluids
Journal of Applied Mechanics, 1971The equations governing the flow of a fluid with rigid, spherical substructure are summarized. A two-dimensional flow field is considered and applied to the geometry of a slider bearing. Order-of-magnitude arguments are used which reduce the governing equations to a system of coupled, linear, ordinary differential equations.

Abstract This chapter reviews the basic theory of lubrication in the context of metal forming applications. It discusses the rheological properties of fluids and their effect on fluid-film thickness at pressures, temperatures, and loading conditions typical of metal working processes. It describes the three lubrication regimes (boundary,
