An advanced head disk interface (HDI) system assisted by gas perfluoropolyether (PFPE) lubrication is discussed in this paper.It is known that lubricant spins off at Standing Wooden Plaque a high rotation speed and high temperature.Lubricant redistribution after long-term seeking operation with near-contact flying has been studied.The spin-off and
This work proposes a subwavelength porous meta-liner with broadband sound absorption from 900 Body to 1,200 Hz.The meta-liner consists of four subunits, which are made up of porous material and hollow coiling slit embedded in it.Each subunit is designed by adjusting the length of its coiling slit to achieve resonance in the target frequency and exa
The purpose of this study was to optimize the level of wheat, pumpkin seed (PSF) and golden flaxseed flour (GFs) that can be used in order to obtain high quality bread.The independent variables levels used were between 90 and 95 % for wheat flour and between 2.5% and 7.5% for Speaker pumpkin seed and golden flaxseed flour.The quality parameters ana
