Junction sequences generated by one-ended transposition
(1985-05)
In the presence of the cognate transposase. plasmids containing a single inverted repeat (IR) sequence of Tn21 or of Tn1721 can fuse efficiently with other plasmids (‘one-ended transposition’) (1, 2). The junctions across ...
Dispersal of Septoria nodorum pycnidiospores by simulated raindrops in still air
(1985-04)
Simulated raindrops, diameter c. 3 or 4 mm, fell 13 m down a raintower onto suspensions of Septoria nodorum pycnidiospores, depth 0.5 mm, or infected straw pieces. Splash droplets were collected on pieces of fixed photographic ...

Electron-beam guiding and phase-mix damping by a laser-ionized channel
(1985-02)
An ultraviolet-laser-ionized channel in low-pressure benzene has been successfully used to guide and focus a 7-kA relativistic electron beam over distances up to 4 m. In addition, phase-mix damping of coherent, transverse ...
Coordinated multisite observations of the variability of BL Lac
(1985)
The authors present the results of multisite observations of the optical polarization of BL Lac, together with some flux measurements, at a time when BL Lac was relatively faint. The level of polarization varies in a manner ...
Infrared spectropolarimetric observations of BNKL : the grain alignment mechanism
(1985)
Spectropolarimetric observations between 8 - 13 μm of BN, IRc 2, 3, 4 and a further region in the Orion infrared complex BNKL are presented. Apart from IRc 2, all show evidence for absorption by aligned grains and have ...
An optical and near-infrared study of the AM Herculis-type binary CW 1103+254
(1985)
All main components of the AM Herculis-type binary CW 1103 + 254 can be distinguished by means of observations encompassing optical and near-IR photometry and polarimetry, together with optical spectroscopy and spectropolarimetry. ...
