Effect of Occlusivity of oil Film by the States of oil Film on thc Skin Surface
Journal of Society of Cosmetic Chemists of Japan, 1979 The occlusivity of oils was determined in vivo by measuring the suppression of transepidermal water loss (TEWL) of the skin. Various emollients were applied to human skin in various forms including powders, solutions, and emulsions of different types having different size distributions and the residual states of the oil films on the skin surface were ...

On the Oil Film Behaviour of Piston Rings : Correction of Effective Pressure Region of Oil Film
Transactions of the Japan Society of Mechanical Engineers, 1977 This paper reports on a theoretical calculating procedure of the oil film behaviour between the piston ring and the cylinder wall. The analysis assumes: (1) that the sliding surface of the ring may be approximated by a parabola; (2) that the oil film viscosity is constant; and (3) that the trailing end of oil film pressure varies according to the ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
