Preharvest high-intensity, pulsed polychromatic light and low-intensity UV-C treatments control Botrytis cinerea on lettuce (Lactuca sativa)

Low Intensity Pulsed Ultrasound (LIPUS)

The application of ultrasound energy at much lower levels than is the current clinical norm is starting to gain ground as a therapeutic possibility. Clearly the applied energy is the same, it is the ‘dose’ which is different – most importantly, the intensity (W cm) – which is MUCH lower – typically 2 or 3 times lower than the lowest setting on most regular clinical machines, with the most commo...

Symptomless, Systemic, and Seedborne Infection of Lettuce by Botrytis Cinerea

LOW INTENSITY PULSED ULTRASOUND TREATMENT INCREASES RABBIT RADIAL FRACTURE HEALING

In order to study the effect of ultrasound (US) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group I. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= I) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a Gigli saw. The ...

integrated-intensity gratings with pulsed light sources

We performed theoretical calculations of the relative diffraction efficiency of partially coherent light-induced integrated-intensity gratings using pulsed sources, paying particular attention to thermal gratings. We provided a simple intuitive picture of the phenomenon and then calculated exact expressions that, unlike instantaneousintensity-grating results, necessarily require the use of four...
