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 ...
Solid-state disk amplifiers for fusion-laser systems
A review is presented of the design, performance, and operation of large-aperture (10-46 cm) solid-state disk amplifiers for use in laser systems. We present design data, prototype tests, simulations, and projections for ...
Alterations in RNA and protein metabolism in uninoculated half-leaves of cowpea adjacent to tobacco necrosis virus infected halves
Following inoculation of half-leaves of cowpea with tobacco necrosis virus (TNV, R 1 : 1.5 19 : S S : S Fu), two major protein fractions, termed α and β appear in soluble extracts, which are absent from sham-inoculated ...
