In this article, in reference to the modified couple stress theory and Euler-Bernoulli beam theory, the free lateral vibration response of a micro-beam carrying a moveable attached mass is investigated. This is a decent model for biological and biomedical applications beneficial to the early-stage diagnosis of diseases and malfunctions of human body organs and enzymes. The micro-cantilever beam...

in the current study, the effects of interactions of the moving loads and the attached mass-spring-damper systems of the composite plates on the resulting dynamic responses are investigated comprehensively, for the first time, using the classical plate theory. the solution of the coupled governing system of equations is accomplished through tracing the spatial variations using a navier-type sol...

the present study is the first to analyze the dynamic response of a poroelastic beam subjected to a moving force. moreover, the influences of attached mass-spring systems and non-ideal supports (with local movements in the supporting points or base due to the presence of factors such as gaps, unbalanced masses, and friction or seismic excitations) on the responses were investigated. non-ideal s...

a 51-year-old man was admitted to the emergency department with palpitation and atypical chest pain. he had a history of percutaneous mitral valve commissurotomy 20 years previously. he did not use any drugs. physical examination was unremarkable except for a loud s1 on auscultation. the surface electrocardiogram (ecg) showed atrial fibrillation rhythmwith rapid ventricular response and right b...

In order to access the characteristics of a NAS (network attached storage) device, a case study approach was used to track the installation of one such device at a Midwestern university. Specifically, the NAS will be evaluated in regard to ease of installation, ease of configuration, ease of upgradability, ease of use by end users, security concerns, and performance characteristics under a vari...

purpose:  to report a patient with pretarsal dermoid cyst. patient and findings: a 2.5-year-old girl presented with a pretarsal upper lid mass and underwent excisional biopsy. a 1.0´1.0 cm cystic mass attached to upper lid tarsus was completely excised. pathologic study of the specimen revealed a dermoid cyst. conclusion: although pretarsal dermoid cyst is rare; it should be considered in all c...
