    Abstract: The invention relates to an extract of black tea (Camellia sinensis) enriched in particular in small RNAs, sugars, phenolic compounds, amino acids and theanine, and to a process for preparing such an extract. The invention also relates to cosmetic compositions comprising such an extract, and to the uses of cosmetic compositions comprising a black tea extract from any source, with the exception of black tea from Mauritius, for caring for the skin, scalp and appendages, and more particularly for protecting the skin from external aggression and oxidation, combating the signs of skin ageing, increasing photoprotection, lightening the skin and improving skin hydration.

    Abstract: Methods and computing apparatus for implementing a radiation dosimetry process. An example process may include exposing a first radiation sensitive film to a series of known doses of radiation, measuring a first set of radiation data with a measurement device, and determining a calibration curve. The calibration curve may be determined by selecting Raman spectral ranges based on the first set of radiation data, determining a plurality of band area ratios, and generating the calibration curve based on plotting the band areas and ratios compared to known dose. The radiation dosimetry process then exposes a second radiation sensitive film to an unknown dose of radiation, measures a second set of radiation data for the second radiation sensitive film with the measurement device, and determines a dose exposure level for the second radiation sensitive film by comparing the second set of radiation data with the calibration curve.

    Abstract: The invention relates to a process for obtaining an aqueous extract of lavender enriched with small RNAs of a maximum length of 150 nucleotides, with sugars, with phenolic compounds, with organic acids and devoid of DNA, obtained by the following process: the lavender aerial parts are brought into contact with water; phytic acid is added at a pH of between 10 and 11; the pH of the mixture obtained is then adjusted to a value of between 6 and 8, the mixture obtained is purified. The invention also relates to cosmetic compositions comprising such an extract and their cosmetic uses for protecting the skin from external aggression and oxidation, combating the signs of skin ageing, increasing photoprotection, lightening the skin, improving hydration, reinforcing the barrier function, soothing the skin or improving the biological mechanisms associated with skin repair during the night.
