Against the Odds: Psychomotor Development of Children Under 2 years in a Sudanese Orphanage. [PDF]
, 2011 Providing abandoned children the necessary medical and psychological care as possible after their institutionalization may minimize developmental delays. We describe psychomotor development in infants admitted to an orphanage in Khartoum, Sudan, assessed

Advanced Theory and Simulations, Volume 9, Issue 1, January 2026.This study develops a superconvergent meshless method to analyze and control vibrations in twisted, bidirectional functionally graded Terfenol‐D beams. By optimizing magnetostrictive patch placement, it demonstrates effective vibration suppression under dynamic loads, highlighting the design potential of strategically graded materials in complex ...

Signal injection and averaging for position estimation of Permanent-Magnet Synchronous Motors
, 2012 Sensorless control of Permanent-Magnet Synchronous Motors at low velocity remains a challenging task. A now well-established method consists in injecting a high-frequency signal and use the rotor saliency, both geometric and magnetic-saturation induced ...

Free Vibration Analysis of Triclinic Nanobeams Based on the Differential Quadrature Method
Applied Sciences, 2019 In this work, the nonlocal strain gradient theory is applied to study the free vibration response of a Timoshenko beam made of triclinic material. The governing equations of the problem and the associated boundary conditions are obtained by means of the ...

Graphene and Carbon Quantum Dots: Competing Carbons in Harmonized Photoelectrochemical Platforms
Small, Volume 21, Issue 40, October 9, 2025.This review discusses the essential roles of carbon quantum dots (CQDs) and graphene quantum dots (GQDs) in photoelectrochemical (PEC) systems. It addresses specific aspects of their 1D properties, nanohybrid combinations, unique functionalization's, and other mechanisms to improve light absorption and charge separation, which provides new ...

Free vibrations of non-uniform CNT/fiber/polymer nanocomposite beams
Curved and Layered Structures, 2017 In this paper, free vibrations of non-uniform multi-scale nanocomposite beams reinforced by carbon nanotubes (CNTs) are studied. Mori-Tanaka (MT) technique is employed to estimate the effective mechanical properties of three-phase CNT/fiber/polymer ...

Transverse Vibration Of Non-Homogeneous Rectangular Plates Of Variable Thickness Using Gdq
, 2014 The effect of non-homogeneity on the free transverse vibration of thin rectangular plates of bilinearly varying thickness has been analyzed using generalized differential quadrature (GDQ) method. The non-homogeneity of the plate material is assumed to arise due to linear variations in Young’s modulus and density of the plate material with the in-plane ...
