Some Aspects of Bioelectrical Phenomena
It is pointed out that there are great advantages in using single cells instead of tissues in the study of bioelectrical phenomena. Certain bioelectrical phenomena are discussed in relation to the structure of protoplasm. Under certain circumstances measurements of potential differences may enable us to determine what ions enter the protoplasm. Under suitable conditions we are able to ascertain...
متن کاملSome Aspects of Bioelectrical Phenomena.*
This brief sketch is intended as an introduction to a series of articles 1 on bioelectrical phenomena, its purpose being to present certain fundamental facts and underlying conceptions. Early in the course of the investigation it became evident that there are great advantages in using single cells in place of tissues. The experiments were accordingly made with single (multinucleate) cells of Va...
متن کاملSolidification Phenomena and Properties of Some Cast Tool Steels
The freezing process. microstructures and phase relationships in some experimental cast tool steels have been investigated and developed under the various solidification conditions. Experimental steels were based on AISI M2 and M10 grades high speed steels. Addition of carbide forming elements such as niobium and titanium with and without extra carbon were made to the molten bath of the base st...
متن کاملNatural Semantics and Some of Its Meta-Theory in Elf
Operational semantics provide a simple, high-level and elegant means of specifying interpreters for programming languages. In natural semantics, a form of operational semantics, programs are traditionally represented as first-order tree structures and reasoned about using natural deduction-like methods. Hannan and Miller combined these methods with higher-order representations using .\Prolog. I...
متن کاملSome Curious Phenomena in Coupled Cell Networks
We discuss several examples of synchronous dynamical phenomena in coupled cell networks that are unexpected from symmetry considerations, but are natural using a theory developed by Stewart, Golubitsky, and Pivato. In particular we demonstrate patterns of synchrony in networks with small numbers of cells and in lattices (and periodic arrays) of cells that cannot readily be explained by conventi...
