Refractive index within the lens of a goldfish eye determined from the paths of thin laser beams
(Elsevier, 1988)
The paths of 15 [mu]m diameter laser beams traversing goldfish eye lenses were photographed. Measurements of these photographs gave experimental data for the distance of the exit point of each ray from the lens axis as a ...
Gadolinium-enhanced 3D magnetic resonance angiography of the thoracic vessels
(John Wiley & Sons, Inc., 1999-11)
Microfilaments and actin-associated proteins at sites of membrane-substrate attachment within acetylcholine receptor clusters
(Elsevier, 1989-06)
Rat myotubes in tissue culture form broad areas of close contact with the substrate. These areas often display two distinct, interdigitating sets of membrane domains. One, the "contact domain", is close to the substrate; ...
Raman and normal mode studies of the polypeptide chain conformations in crystalline magnesium and calcium poly(-glutamate)s
(Elsevier, 1985)
An analysis of the Raman spectra of dry crystalline magnesium and calcium poly(-glutamate)s, based on a normal mode calculation of [alpha]-helical poly(-glutamate), shows that the polypeptide chains in both salts have an ...
A polarized photobleaching study of chromatin reorientation in intact nuclei
(Elsevier, 1990-08-20)
Polarized fluorescence recovery after photobleaching (pFRAP) was used to monitor the effects that condensation, i.e. compaction and aggregation, have on the ([mu]s and ms) internal dynamics of chromatin in intact nuclei. ...
Normal-mode analysis of infrared and Raman spectra of poly(vinyl fluoride)
(Elsevier, 1992-03-02)
Infrared and Raman spectra of samples of poly(vinyl fluoride) (PVF) have been recorded. The vibrational spectra have been analyzed by means of normal-mode calculations. A force field was derived by using 2-fluorobutane as ...
Carbon suboxide as a quasilinear molecule with a large amplitude bending mode : Determination of the molecular constants and the [nu]7 potential function
(Elsevier, 1976-12)
The model of a quasilinear molecule with a large amplitude bending mode is used to treat C3O2. The Hamiltonian operator, including the rotation-vibration interaction, is derived allowing only a single vibrational degree ...
Lithopanspermia in Star-Forming Clusters
(Mary Ann Liebert, Inc., publishers, 2005-08-01)
This paper considers the lithopanspermia hypothesis in star-forming groups and clusters, where the chances of biological material spreading from one solar system to another is greatly enhanced (relative to action in the ...
Lateral motion of membrane proteins and biological function
(Springer-Verlag; Springer-Verlag New York Inc., 1983-02)
