Quantitative studies on dispersal of Pseudocercosporella herpotrichoides spores from infected wheat straw by simulated rain
(1983)
Splash dispersal ofPseudocercosporella herpotrichoides spores from infected wheat straw was investigated using simulated rainfall (rate 13.8l h−1 m−2, volume mean diameter 2.9 mm) and wind (2 m sec−1) in a raintower/wind ...
Dispersal of Erwinia carotovora subsp. atroseptica in splash droplets
(1983)
Water drops, diameter 4 mm, fell 13 mm onto suspensions of cells ofErwinia carotovora subsp.atroseptica containing Mg (ANS) dye. The resulting splash droplets were collected on ohotographic film, on Petri plates containing ...
Recovery of Pseudocercosporella herpotrichoides Spores from Rain-Splash Samples
(1983)
Methods for recovery of P. herpotrichoides spores from rain-splash were tested, initially with pure spore suspensions and then with field samples. Provided surfactant was added and samples were processed immediately, ...
Large aperture harmonic conversion experiments at Lawrence Livermore National Lanoratory
(1982-10)
Large aperture harmonic conversion experiments to 2 omega (532 nm), 3 omega (355 nm), 4 omega (266 nm) on the Argus laser at the Lawrence Livermore National Laboratory are described. Harmonically converted energies of up ...
Molecular cloning and characterisation of the two DNA components of tomato golden mosaic virus
(1982-08-25)
We report the molecular cloning of the tomato golden mosaic virus (TGMV) genome in the E. coli plasmid pAT 153. The results of this work conclusively show that TGMV DNA consists of two components (designated A and B) of ...
Gain saturation in Nd:doped laser materials
(1982-07)
Saturation of gain in Nd:doped silicate, phosphate, and fluorophosphate glasses, and in doped crystals of YAG and YLF was observed during amplification of 1064 and 1053 nm pulses with durations of 1. 0, 9. 0, and 50 ns. ...
The variable infrared source near HH100
(1982)
Photometric observations are presented which confirm the high variability, of up to 2.5 mag at K, of the IR source associated with the Herbig-Haro object HH100, and it is suggested that such a large variation must be a ...
