Large aperture harmonic conversion experiments at Lawrence Livermore National Lanoratory
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
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
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. ...
Use of triple-labelled nutrient solution to study the effects of root-infecting fungi on uptake of potassium, calcium and phosphorus by wheat
Triple-labelled nutrient solution was used to compare the effects of seven root-infecting fungi on uptake of K, Ca and P by wheat. Plants grown in sand or hydroponic culture were transferred to solutions that contained42K,45Ca ...
Measurement of spore-carrying splash droplets using photographic film and an image-analyzing computer
An improved method for the sampling of splash droplets carrying fungal spores uses fixed photographic film. Droplets left clear, permanent traces within which spores were easily visible. The droplet spread factor was ...
The variable infrared source near HH100
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 ...
