Lubrication and Lubricants A Treatise on the Theory and Practice of Lubrication, and on the Nature, Properties, and Testing of Lubricants [PDF]

open access: yesNature, 1907
THIS work may be divided into two parts, which, in fact, have little connection with one another, The first is that which deals with the chemical and physical properties of lubricants generally, and will appeal more particularly to analytical chemists, to whom samples of lubricants are submitted for the purpose of estimating their commercial value.

Bio-Mechanical and Bio-Rheological Aspects of Sickle Red Cells in Microcirculation: A Mathematical Modelling Approach

open access: yesFluids, 2021
Sickle cell disease (SCD) is an inherited monogenic disease characterized by distorted red blood cells that causes vaso-occlusion and vasculopathy. Presently, electrophoresis of haemoglobin and genotyping are used as routine tests for diagnosis of the ...

The Theory of Lubrication

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1951
When we deal theoretically with the subject of the lubrication, we treat it on the supposition that the viscosity of the lubricant is constant for the convenience of the calculation. But we can't regard it as constant, owing to the fact that the lubricant in bearing is affected by the pressure and temperature.
