Does Pool Performance of Elite Triathletes Predict Open-Water Performance? [PDF]
Journal of Functional Morphology and Kinesiology, 2023 The capacity of laboratory tests to predict competition performance has been broadly researched across several endurance sports. The aim of the present study was to analyse how pool swimming performance can predict the result of the swimming segment in ...

Investigations of the surface conductivity of silicon dioxide and methods to reduce it [PDF]
, 1987 In this paper we describe our investigations of the electrical conductivity of the silicon dioxide-air interface. It appears that this conductivity is caused by the adsorption of water vapour on the oxide surface and strongly depends on the relative ...
