the present paper investigates the potential application of graphene sheets with attached nanoparticles as resonant sensors by introducing a nonlocal shear deformation plate model. to take into account an elastic connection between the nanoplate and the attached nanoparticle, the nanoparticle is considered as a mass-spring system. then, a combination of pseudo-spectral and integral quadrature m...

The present paper investigates the potential application of graphene sheets with attached nanoparticles as resonant sensors by introducing a nonlocal shear deformation plate model. To take into account an elastic connection between the nanoplate and the attached nanoparticle, the nanoparticle is considered as a mass-spring system. Then, a combination of pseudo-spectral and integral quadrature m...

The frequency equation of carbon-nanotube-based cantilever sensor with an attached mass is derived analytically using nonlocal elasticity theory. According to the equation, the relationship between the frequency shift of the sensor and the attached mass can be obtained. When the nonlocal effect is not taken into account, the variation of frequency shift with the attached mass on the sensor is c...

Nonlocal vibration of double-smart nanobeam-systems (DSNBSs) under a moving nanoparticle is investigated in the present study based on Timoshenko beam model. The  two  smart  nanobeams (SNB) are  coupled  by  an  enclosing  elastic  medium  which  is  simulated  by  Pasternak foundation. The energy method and Hamilton’s principle are used to establish the equations of motion. The detailed param...

vaginal leiomyomas are uncommon benign tumour with variable clinical presentation. these tumours arise most commonly from anterior vaginal wall. we report a case of 50-year old postmenopausal woman who presented with urinary retention, profuse vaginal bleeding and mass protruding into vagina. local examination revealed a pedunculated mass attached to the posterior vaginal wall with vascular sta...

primary localized amyloidosis of eyelid is a localized type of amyloidosis without evidence of systemic involvement. we report a 75-year-old man suffering of unilateral (left) ptosis due to upper eyelid mass with bony consistency. eye examination revealed upper lid mass attached to tarsus. no ocular infection or inflammation was found. pathologist reported diffuse distribution of eosinophilic h...

Animal-borne logging devices are now commonly used to record and monitor the movements, physiology behaviours of free-living animals. It is imperative that impacts these have on animals themselves minimised. One important consideration interaction between body mass animal device. Using captive homing pigeons, we demonstrate birds lose equivalent amount compared device attached. With our experim...
