Effect of Potassium on A-V Conduction [PDF]
Circulation, 1970 "When the potassium is injected slowly, after a time the heart gradually slows to perhaps half its normal rate, the auricle and ventricle being markedly dilated but still contracting synchronously. This is an example of sinus slowing, and is probably due to the direct action of the salt upon what Lewis has termed the `pace-maker' of the heart; it is ...

Heat conduction in polymer chains: Effect of substrate on the thermal conductance
The Journal of Chemical Physics, 2022 In standard molecular junctions, a molecular structure is placed between and connected to metal leads. Understanding how mechanical tuning in such molecular junctions can change heat conductance has interesting applications in nanoscale energy transport.

In situ mixing of organic matter decreases hydraulic conductivity of denitrification walls in sand aquifers [PDF]
, 2008 In a previous study, a denitrification wall was constructed in a sand aquifer using sawdust as the carbon substrate. Ground water bypassed around this sawdust wall due to reduced hydraulic conductivity.

Witnessing unethical conduct: the effects
BMJ, 2001 A consultant oncologist examines a woman who has previously had breast cancer. As he performs the physical examination, the doctor feels a suspicious breast lump, and he tells the woman what he has found. She starts to cry. But he seems not to notice, and carries on examining her, ignoring her obvious distress and need for support. The medical students

Polarization versus Mori-Tanaka approximations for effective conductivity of isotropic composites
Vietnam Journal of Mechanics, 2018 Our polarization approximations for the effective conductivity of isotropic multicomponent materials, constructed recently as approximate solutions to the minimum energy principles, are compared with the widely used Mori-Tanaka approximation, derived as
