The linear stability of the responses of axially moving beams supported by an intermediate spring
(EDP Sciences, 2016)
In the present paper, the stability investigation of the linear responses of axially travelling beams supported by an intermediate linear spring is performed numerically by means of searching linear complex eigenvalues. ...
Biological strategies to counteract the effects of mycotoxins
(International Association for Food Protection, 2009)
Mycotoxins are fungal secondary metabolites that if ingested can cause a variety of adverse effects on both humans and animals, ranging from allergic responses to death. Therefore, exposure to mycotoxins should be minimized. ...
Effect of tooth profile modification on wear in internal gears
(IOP Publishing Ltd, 2018)
Internal gears are often used in the automotive industry when two gears are required to rotate in the same direction. Tooth shapes, slippage speeds at the beginning and end of meshing are different according to the external ...
