A new strategic tool for managing the economic recession: Creating shareholder value with lateral marketing
(2011)
Mortgage crisis, which started in 2007 and is still ongoing, has caused a big economic recession in the world economy. That recession made business managements to do important strategically and institutional reactions ...
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. ...
Investigation of immobilization and kinetic properties of catalase enzyme on poly(HEMA-GMA) cryogel
(Slovak Academy of Sciences Institute of Experimental Physics Department of Biophysics, 2017)
Catalase is a metalloenzyme, which is found in almost all aerobic respiratory organisms. This enzyme acts as a detoxification agent for the hydrogen peroxide (H2O2) compound, protecting tissues and cells from oxidative ...
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 ...
