Nanobeams are now widely used in numerous vibration frequency research. In this study, an eigenvalue problem has to determine the analysis of buckyball and spring attached end nanobeam. The frequencies system may be discovered using a single (2x2) matrix problem. A mathematical method for analyzing sensors nanobeams is presented paper. results, which obtained showed result that compatible with ...

Left ventricular (LV) mass is a rare condition, of which the most common is thrombus. Echocardiography is a very useful modality of investigation to evaluate the LV mass. We are reporting a case of LV mass presenting with neurological symptom. The diagnosis of this mass was dilemma as the echocardiographic features were favoring tumor as well as thrombi. Mass (a) measuring 3.8 cm × 1.9 cm attac...

Introduction: Lipomas of the larynx are very rare benign lesions; macroscopically, they resemble retention cysts, so their diagnosis is usually made after surgery.   Case Report: A rare case of pediatric paraglottic space Lipoma in an 11-year-old boy is explained. The mass was mobile, soft, without fluctuation or pulsation. CT scan revealed a 5.7 cm cervical fat density with regional lymphadeno...

Nanoelectromechanical resonator sensors based on graphene sheets (GS) show ultrahigh sensitivity to vibration. However, many factors such as the layer number and dimension of the GSs will affect the sensor characteristics. In this study, an analytical model is proposed to investigate the vibration behavior of double-layered graphene sheets (DLGSs) with attached nanoparticles. Based on nonlocal ...

The examination of variation of elastic modules in single wall carbon nanotubes (SWCNTs) is the aim of this paper. Full nonlinear spring-like elements are employed to simulate specific atomic structures in the commercial code ABAQUS. Carbon atoms are attached to each node as a mass point using atomic mass of carbon atoms. The influence of dimensions such as variation of length, diameter, aspect...

pedunculated chorangioma is extremely rare type of chorangioma. to the best of our knowledge, no case has been reported in indian literature. we report one such rare case in a twenty two year old primi gravida who delivered a full term live female baby by lower section caesarian section (lscs). gross examination revealed a nodular mass attached to the placenta by a pedicle. histopathological ex...

In this paper, we consider a fractional nonlinear oscillator for mass attached to stretched elastic wire. The coupling technique based on the complex transform and global residue harmonic balance method is proposed solving oscillator. approximated periodic solutions frequencies are provided without complicated computation discretization. frequency–amplitude relationship investigated show its mo...
