Forced Vibration Analysis of Composite Beams Reinforced by Carbon Nanotubes

Nanomaterials, 2021
This paper presents forced vibration analysis of a simply supported beam made of carbon nanotube-reinforced composite material subjected to a harmonic point load at the midpoint of beam. The composite beam is made of a polymeric matrix and reinforced the

Base-editing corrects metabolic abnormalities in a humanized mouse model for glycogen storage disease type-Ia

Nature Communications
Glycogen storage disease type-Ia patients, deficient in the G6PC1 gene encoding glucose-6-phosphatase-α, lack blood glucose control, resulting in life-threatening hypoglycemia. Here we show our humanized mouse model, huR83C, carrying the pathogenic G6PC1-

Natural vibrations of a beam on stochastic two-layered subsoil with significantly different thickness

Budownictwo i Architektura, 2014
In this paper the influence of variability of Young modulus of the subsoil layers on the natural frequency of the beam-two-layered subsoil system was analyzed. Assuming the first layer was thinner and more rigid then the second one (10 and 20 times). The

Dynamic Stability of the Periodic and Aperiodic Structures of the Bernoulli-Euler Beams [PDF]

Archives of Metallurgy and Materials
The study analyzed the influence of periodic and aperiodic stiffness distribution for the four-element Bernoulli-Euler beam on the first two eigenfrequencies and the dynamic stability of the system. The influence of increasing the ratio of cross-sections

Nonlinear Wave Equation for Ultrasound Beam in Nonuniform Bubbly Liquids

Journal of Fluid Science and Technology, 2011
In our previous paper (Kanagawa et al., J. Fluid Sci. Tech., 5, 2010), we have proposed a systematic method for derivation of various types of nonlinear wave equations for plane waves in bubbly liquids.

Luminosity Loss due to Beam Distortion and the Beam-Beam Instability [PDF]

Proceedings of the 2005 Particle Accelerator Conference, 2006
In a linear collider, sources of emittance dilution such as transverse wakefields or dispersive errors will couple the vertical phase space to the longitudinal position within the beam (the so-called ‘banana effect’). When the Intersection Point (IP) disruption parameter is large, these beam distortions will be amplified by a single bunch kink ...
