The effect of solution composition on microtubule dynamic instability
(1991)
The exchange of tubulin dimer into steady-state microtubules was studied over a range of solution conditions, in order to assess the effects of various common buffer components on the dynamic instability of microtubules. ...
Near-infrared imaging polarimetry of bipolar nebulae 1:the BN-KL region of OMC-1
(1991)
New high-spatial-resolution polarization images of the BN-KL region of OMC-1 from 1.25-3.6 microns are presented. At the longer wavelengths these show a centro-symmetric polarization vector pattern, centered mainly on IRc2, ...
Ultraviolet observations of the long-period dwarf nova DX and in outburst
(1991)
Ultraviolet observations of the little-studied dwarf nova, DX And, are presented. The observations were made with the International Ultraviolet Explorer satellite during the late stages of a rise to outburst maximum in ...
Opposite-end behaviour of dynamic microtubules
(1991)
Microtubules are dynamic polar structures with different kinetic properties at the two ends. The inherent asymmetry of the microtubule lattice determines that the relationship between the addition reaction of tubulin-GTP ...
Near-infrared imaging polarimetry of bipolar nebulae. 4: GL-490, GL-2789, GL-2136
(1991)
High spatial resolution near-IR polarization and surface brightness images of the ouflow sources GL 490, GL 2789 and GL 2136 are presented. Polarization vector-maps at J, H and K show centro-symmetric patterns around GL ...
Boundary-layer temperatures in high accretion rate cataclysmic variables
(1991)
The Zanstra method is used to derive limits on boundary-layer temperatures in eclipsing dwarf novae during outburst and nova-like variables, using the observed He II 1640 and 4686 A recombination lines. It is assumed that ...
Algebraic connectivity
(1991)
A multiband 2-beam optical and infrared polarimeter
(1991)
A new polarimeter capable of simultaneous observations in the U, B, V, R and I optical bands and one of the J, H, K, L and M near-infrared bands has been constructed. The polarimeter has good polarization efficiency and ...
