Slow Flow of Couple Stress Fluid Past a Cylinder Embedded in a Porous Medium: Slip Effect

Engineering Transactions, 2023
An analytical study for the creeping flow of a couple stress fluid past a cylinder embedded in a porous medium is presented using the slip condition. The uniform flow is considered far away from a cylinder.

Modelling the Size Effects on the Mechanical Properties of Micro/Nano Structures

Sensors, 2015
Experiments on micro- and nano-mechanical systems (M/NEMS) have shown that their behavior under bending loads departs in many cases from the classical predictions using Euler-Bernoulli theory and Hooke’s law. This anomalous response has usually been seen

Influence of Temperature Pulse on a Nickel Microbeams under Couple Stress Theory [PDF]

Journal of Applied and Computational Mechanics, 2020
In this paper, the vibration of microbeams due to a temperature pulse has been investigated. The thermoelastic coupled equations for microbeam resonator have been derived via the modified theory of couple stress in connection with the generalized ...

Study of the Couple Stress Convective Micropolar Fluid Flow in a Hall MHD Generator System

Frontiers in Physics, 2019
The steady non-isothermal convective heat transfer in magnetohydrodynamic micropolar fluid flow over a non-linear extending wall is examined. The fluid flow is treated with strong magnetic field.

Enhanced performance of step slider bearings with couple stress and magnetic fluid lubrication incorporating sinusoidal magnitude: A theoretical investigation

Journal of Mechanical Engineering and Sciences
Step slider bearings play a critical role in tribological applications, particularly within high-precision mechanical systems, where their operational efficiency is significantly influenced by the nature of the lubricant and its rheological response to ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...
