A numerical solution to Hodgkin and Huxley's partial differential
system for the propagated action potential is presented. In
addition a three dimensional demonstration of the absolute refractory
period is given. Lastly, theoretical evidence supporting
Rushton's hypothesis is presented.
There are numerous references in the literature concerning
the use of various Arctostaphylos species as medicinal plants.
One of the species, A. uva-ursi, was listed in the United States
official compendia from 1820 until 1946 as a urinary antiseptic.
Many species indigenous to the Pacific Northwest were employed
by the...
Behavioral responses exhibited by the Douglas-fir beetle,
Dendroctonus pseudotsugae Hopkins, to various attractant sources
were investigated under both laboratory and field conditions. Tests
were designed to observe olfactory responses. Results were correlated
and compared with collections from sampling nets and with
emergence patterns. Field data were collected during the flight...
A pharmacognostic study was made of the root of Heracleum
mantegazzianum, an umbelliferous species which is of value as a
source of natural coumarins.
Three groups of seeds were tested to determine the presence
of a germination requirement for moist cold and the possible value
of gibberellic acid in obviating...
A survey of scholarly and popular contemporary literature
reveals two persisting stereotypes regarding the
nature of women.
First is the theory that woman is inferior to man
and that since she is the "negative" of man's masculine
nature, she cannot develop her humanity to the fullest
extent without fusion with...
A multivariable model describing the system response
(weld tensile strength of 6061-T6 aluminum) of a percussive
stud welding system as a function of five natural
(external) system variables was developed. The five natural
system variables were 1) static weight of the drop-shaft (W), 2) initial stud base height (H₀), 3)...
The simplified equations of motion proposed by Morton to determine
the extent of vertical travel of a forced plume in a linear
density stratified environment were re-written and solved in a way
which allowed them to be applied to any non linear profile of density.
For application to any specific...
