An investigation into the simultaneous use of a resonator as an energy harvester and a vibration absorber
(Elsevier B.V., 2014-02-28)
A mass-spring-damper system is at the core of both a vibration absorber and a harvester of energy from ambient vibrations. If such a device is attached to a structure that has a high impedance, then it will have very little ...

Optimal parameters and characteristics of a three degree of freedom dynamic vibration absorber
(American Society of Mechanical Engineers, 2012-04)
The present study is devoted to the determination of the optimal parameters and characteristics of a three degree of freedom dynamic vibration absorber (3 DOF DVA) for the vibration reduction of a plate at a given point. ...

UV-absorbing compounds in Porphyra haitanensis (Rhodophyta) with special reference to effects of desiccation
(Springer, 2008-08)
The intertidal red alga Porphyra haitanensis Chang et Zheng is episodically desiccated and exposed to high levels of solar radiation at low tide during emersion. However, little has been documented on the relationship ...
New methods to quantify NH3 volatilization from fertilized surface soil with urea
(Sociedade Brasileira de Ciência do Solo, 2011-01-01)
Gaseous N losses from soil are considerable, resulting mostly from ammonia volatilization linked to agricultural activities such as pasture fertilization. The use of simple and accessible measurement methods of such losses ...
