A thin film lead zirconate titanate Pb(Zr,Ti)O3 (PZT), power generating device is developed. It is designed to resonate at specific vibrational frequencies from an ambient, vibrational energy source, thereby creating electrical energy via the piezoelectric effect. The energy harvesting device uses the piezoelectric d33 mode and is fabricated with three mask steps. Our cantilever device was desi...

Middle cerebral artery dissection (MCAD) is a rare cause for ischemic stroke and is often associated with headache and hemispheric symptoms. In the present report, limb shaking is found to be a major symptom of spontaneous MCAD in a young male. The diagnosis of MCAD is based on the intramural hematoma directly visualized in MR T2-weighted images and supported by serial evolution of transcranial...

In this study, shaking table tests are performed to investigate the behavior of excess pore water pressure in different soft soil-foundations of soil-structure interaction (SSI) system. The variation of the behaviors under cycled minor shock is observed. Moreover, The generation and variation mechanism of excess pore water pressure under earthquake excitation in different soft soilfoundations a...

We show that weakly bound molecules can be probed by "shaking" in a pulsed nonresonant laser field. The field introduces a centrifugal term which expels the highest vibrational level from the potential that binds it. Our numerical simulations applied to the Rb(2) and KRb Feshbach molecules indicate that shaking by feasible laser pulses can be used to accurately recover the square of the vibrati...

BACKGROUND Among disposable bioreactor systems, cylindrical orbitally shaken bioreactors show important advantages. They provide a well-defined hydrodynamic flow combined with excellent mixing and oxygen transfer for mammalian and plant cell cultivations. Since there is no known universal correlation between the volumetric mass transfer coefficient for oxygen kLa and relevant operating paramete...

We study a gas of interacting ultracold bosons held in parabolic trap the presence an optical lattice potential. Treating system as discretized Gross-Pitaevskii model, we show how Floquet engineering, by rapidly ``shaking'' lattice, allows ground state to be converted into train bright solitons inverting sign hopping energy. number produced depends on system's nonlinearity and curvature trap, t...

Over the past three years 15 children have been admitted to the paediatric intensive care unit (PICU) at Addenbrooke's hospital suspected of having non-accidental injuries; presentation was diverse and often mild and out of proportion to the degree of morbidity seen at discharge and follow up. When compared with a group of similar aged children admitted to the PICU with severe head injury cause...

Shaken baby syndrome is the most common cause of death or serious neurological injury resulting from child abuse. It is specific to infancy, when children have unique anatomic features. Subdural and retinal haemorrhages are markers of shaking injury. An American radiologist, John Caffey, coined the name whiplash shaken infant syndrome in 1974. It was, however, a British neurosurgeon, Guthkelch ...

this study aims to investigate and optimize the effects of the main parameters including the particle size, gravity and magnetic separation combination, high gradient magnetic separation, magnetic field intensity, shaking table slope, washing water flow, and electrostatic separation upon the rare earth element (ree) recoveries from iron mine waste. the electron microprobe showed that high amoun...
