This paper presents the acceleration sensitivity and the resulting vibration-induced phase noise of an electrostatically coupled encapsulated silicon microresonator. External vibrations can produce phase noise in microresonators by generating time-varying stress in the resonant beams. A spring mounted resonator design that reduces the induced axial stress is presented here. Measurements and sim...

Roads have been associated with behavioral and physiological changes in wildlife. In birds, roads decrease reproductive success and biodiversity and increase physiological stress. Although the consequences of roads on individuals and communities have been well described, the mechanisms through which roads affect birds remain largely unexplored. Here, we examine one mechanism through which roads...

Background: Saffron consists of dried stigmas and top of the styles of crocus sativus. It has various applications such as sexual potential stimulant, anti spasm, anti depression, sedative ,anti inflammation and anti cancer. Materials and Methods: In present study, 200 male adult rats divided to five groups with 10 rats per each cage and with four replicate for each group. Solvent of saffron wa...

Electronic waste (e-waste) is a growing occupational and environmental health issue around the globe. E-waste recycling is a green industry of emerging importance, especially in low-and middle-income countries where much of this recycling work is performed, and where many people's livelihoods depend on this work. The occupational health hazards of e-waste recycling have not been adequately expl...

Aims Epidemiological studies indicate that traffic noise increases the incidence of coronary artery disease, hypertension and stroke. The underlying mechanisms remain largely unknown. Field studies with nighttime noise exposure demonstrate that aircraft noise leads to vascular dysfunction, which is markedly improved by vitamin C, suggesting a key role of oxidative stress in causing this phenome...

Environmental noise is a known stress, which induces alterations of various physiological responses in individuals exposed to it. Stress has been shown to cause changes in the perception of various sensations including pain and stress-induced analgesia has been observed following exposure to a diverse set of stimuli. To examine the algesic behavior of rats exposed to loud environmental noise, f...

Sounds can induce autonomic responses in listeners. However, the modulatory effect of specific frequency components of music is not fully understood. Here, we examined the role of the frequency component of music on autonomic responses. Specifically, we presented music that had been amplified in the high- or low-frequency domains. Twelve healthy women listened to white noise, a stress-inducing ...
