  • 1 July 1994
This review describes the basic principles of electrophysiology using the generation of an action potential in characean internodal cells as a pedagogical tool. Electrophysiology has proven to be aExpand

The Actin Cytoskeleton and Polar Water Permeability in Characean Cells
The hydraulic resistance was measured on internodal cells of Chara corallina and Nitellopsis obtusa using the method of transcellular osmosis described by Kamiya and Tazawa in 1956. The transcellularExpand

Dimensions, Density, and Settling Velocity of Entomophthoralean Conidia: Implications for Aerial Dissemination of Spores
Abstract The epizootic behavior of entomopathogens is determined, in part, by their capacity for spatial spread in a host population. Among the entomophthoralean fungi, this may be accomplishedExpand

The Atomic Composition of Onoclea sensibilis Spores
It is generally accepted that fern spores contain all the elements that are needed for germination because spores germinate on distilled water in the absence of added nutrients (Raghavan, 1980). HereExpand

Fibre cables in the lacunae of Typha leaves contribute to a tensegrity structure.
BACKGROUND AND AIMS Cables composed of long, non-lignified fibre cells enclosed in a cover of much shorter thin-walled, crystal-containing cells traverse the air chambers (lacunae) in leaves of theExpand

Intracellular pH does not change during phytochrome-mediated spore germination in Onoclea
Abstract Calcium ions may act as a “second messenger” in phytochrome-mediated spore germination in Onoclea sensibilis L. In this study we determine whether changes in intracellular pH also contributeExpand

THE FIZEAU EXPERIMENT: EXPERIMENTAL INVESTIGATION OF THE RELATIVISTIC DOPPLER EFFECT
We built a Fizeau interferometer that takes advanta ge of laser light, digital image capture and comput er analysis to reproduce the celebrated experiments of Fizeau, Mic helson & Morley, and Zeeman,Expand

The Relativity of Simultaneity: An Analysis Based on the Properties of Electromagnetic Waves
The determination of whether two distant events are simultaneous depends on the velocity of the observer. This velocity dependence is typically explained in terms of the relativity of space and timeExpand

A Fundamental, Relativistic and Irreversible Law of Motion: A Unification of Newton's Second Law of Motion and the Second Law of Thermodynamics
Temperature is an outsider in the laws of motion gi ven by Newton and Einstein and this oversight is th e source of the predictions of time-reversal-invariance made by the se two great systems ofExpand
