Abstract: A plurality of apparatus herein includes a locomotion device, a storage space with straps configured to be carried on a user's back, a trolley, or a wheelbarrow that each have a reflector body extending therefrom to which is mounted a UV-C light source operatively positioned relative to a reflector and operatively temperature controlled by an on-board temperature control unit to form a panel. The UV-C light source is operatively controlled to administer a dose of UV-C light based on a duration of exposure of at most two seconds when the panel has an optical power density between 300 W/m2 and 3000 W/m2 and a surface area of 0.01 m2 to 5 m2. The dose is in a range of 100 J/m2 to 1600 J/m2 as the locomotion device moves at an operating speed in a range of 1 km/hr to 10 km/hour.
Abstract: The present description relates to an injectable emulsion comprising an amphiphilic compound, a first phase comprising droplets including at least one perfluorocarbon compound and a second phase, which is aqueous. The droplets have a diameter d4,3 of between 0.5 pm and 5.5 pm, and the at least one perfluorocarbon compound has a boiling point above 100° C. The present description also relates to methods comprising administering such an injectable emulsion in, for example, ultrasound ablation surgery (FIG. 3).

Abstract: A mobile light exposure device that delivers light pulses to a plant material has a first emission module that has at least one light treatment panel configured to emit one or more light pulses; has a second module configured for adjusting and/or switching on an optical power density of the light treatment panel and optionally a temperature of the light treatment panel; and has a locomotive means for moving the mobile light exposure device. In operation, the mobile light exposure device attenuates impacts on plant material associated with abiotic stresses, such as stresses associated with edaphic, climatic and/or chemical factors.

Abstract: A mobile light exposure device or improving the yield and quality of biological material has a first module for emitting one or more light pulses, which includes a light treatment panel whose surface area is between 0.01 m2 and 10 m2, a second module or adjusting the optical power density of the treatment panel and optionally adjusting the temperature of the panel, and a means of locomotion for moving the device at a speed of between 1 and 10 km/h. The optical power density of the panel is between 100 W/m2 and 10,000 W/m2, preferably between 300 W/m2 and 3,000 W/m2, and the light pulses delivered to the biological material are of identical or different wavelengths and of durations less than or equal to two seconds.
Abstract: A process of preparation of a solid and/or liquid totum or filtrate that includes placing in contact via mixing a vegetal matrix or part of a vegetal matrix with a solvent, extracting, solubilizing and/or formulating the mixture, optionally, filtering the mixture, and recovering the totum or the filtrate thus obtained. The solvent is glycerol monolaurate.
