The Pressure of Radiation [PDF]
Nature, 1913 WITH reference to my letter on this subject in NATURE of December 18, the majority of my correspondents complain that, although I may have indicated the possibility of my own view, I have not shown why the simpler relation, that the pressure is always one-third of the energy density, is untenable. As I cannot reply to each individually, I shall be glad

Colloids and InterfacesThe hydrophilic–lipophilic balance (HLB) is a valuable parameter used to determine the relative hydrophobicity of a compound based on its chemical structure. This semi-empirical parameter has been instrumental in formulating oil-in-water and water-in-oil

Intracranial Pressure—Theory of the Driving Pressure and a New Pressure Index
Neurologia medico-chirurgica, 1978 In order to understand the pathogenesis of increased intracranial pressure, the concept of the driving pressure (DP) from the intracranial vascular system was proposed. The DP consists of combined pressure continuously transmitted from the arterial pressure (ADP) and venous pressure (VP) systems.
