Frequency spectrum of the human head–neck to mechanical vibrationsdoi:10.1177/1461348417747179Bin YangZheng ShiQun WangZhong Liang Miao
There are multiple structures in cells that act as electronic components. If biological tissues and components of biological tissues can receive, transduce and transmit electric, acoustic, magnetic, mechanical and thermal vibrations then this may help explain such phenomena as: 1. Biological reactions t...
Capturing energy from ultra-low frequency vibrations and human motion through a monostable electromagnetic energy harvester 来自 EconPapers 喜欢 0 阅读量: 223 作者:K Fan,M Cai,H Liu,Y Zhang 摘要: In the energy-harvesting field, one of the key issues is how to realize efficient energy ...
The randomness of genetic mutations is another area where science has fallen short. They are by no means random. As creative beings, we create the mutations we need to survive—but only when we have grown ourselves enough to do so. This is the checks and balances system that is built into...
At which frequency is the sound audible to human beings? [A] Fewer than about 20 vibrations per second. [B] More than about 20,000 vibrations per second. [C] About in a range of 20 and 20,000 vibrations per second. [D] 120 vibrations per second.的答案是
This triggers a process of natural body recovery and healing; this results in the vibrations traveling to the different parts of the body while positively impacting the vagus nerve and helping attract money. On the other hand, low vagal energy has been found to have the opposite effect, thus...
In this paper, we report a two-degree-of-freedom (2-DOF) nonlinear EMEH with intent to scavenge energy from ultra-low frequency vibrations and human motion. The 2-DOF EMEH is realized simply by encapsulating and magnetically levitating a 1-DOF EMEH within a cylindrical housing. The 1-DOF ...
In this study, four poroelastic finite element models of human L2鈥揕3 spinal motion segments, including the non-degeneration and the mild, moderate, and serious degeneration, were established. One-hour low-frequency vibrations with different frequencies were applied. Then, the dynamic mechanical ...
Electromagnetic theory pairs with the frequency theory strongly in the design of sound systems in churches and concerts all over the world. We use a magnet to project our voices every time we speak into a microphone. The sound wave is translated into an electromagnetic wave and then transmitted...
Seismic noise is made from vibrations (continuous shaking movements) in the ground that are caused by things like ocean waves and human activity, such as construction work and traffic. This noise makes it difficult for scientists to pick up seismic activity that is made at the s...
