Efficacy in Clinical Studies of a Skin Care Serum Formula Containing 7 Short and Long Saccharides and Bacterial Fractions to Repair and Strengthen the Skin Barrier From Aggressions in Intense Conditions. [PDF]

J Cosmet Dermatol
ABSTRACT Background A healthy skin barrier is essential to protect against the entry of harmful substances or the loss of internal fluids, especially water and electrolytes. Various aggressions are known to weaken the skin barrier. Aims To evaluate single or multiple applications of a serum formula designed to mitigate skin barrier dysfunction and ...

Large Variations in the Transpiration of Sorghum Canopies Under High Evaporative Demand Are Positively Related to Water Use Efficiency. [PDF]

Plant Cell Environ
ABSTRACT Transpiration restriction under high vapour pressure deficit (VPD), measured indoors with individual plants, increases water use efficiency (WUE). However, VPD is not the only factor driving transpiration, individual plants in a field rapidly become a canopy, and reports on the transpiration restriction versus WUE are scant.

Variation of Seasonal Temperature and Water Stress Modify the Composition of Leaf Essential Oils in Grapefruit (Citrus x aurantium var. paradisi), Sweet Orange (Citrus x aurantium var. sinensis) and Clementine (Citrus x aurantium var. clementina) Trees. [PDF]

Chem Biodivers
ABSTRACT Mainly grown for food, citrus trees are also highly used as sources of aromatic essential oils (EOs) by the cosmetics and perfume industries. The EOs composition is highly complex with more than hundred compounds. It varies according to cultivation techniques, climatic conditions, and environmental stresses, whether of biotic or abiotic origin.

Experimental study of the influence of the relative humidity of leaves and their link to adhesion losses in the wheel-rail contact

Mechanics & Industry, 2022
Every autumn, low levels of wheel–rail contact adhesion caused by leaves on the railhead surface are reported by train drivers. These incidents cause problems for the safety and regularity of rail traffic and occur predominantly at the beginning and end ...

Atmospheric moisture supersaturation in the near-surface atmosphere at Dome C, Antarctic Plateau [PDF]

Atmospheric Chemistry and Physics, 2017
Supersaturation often occurs at the top of the troposphere where cirrus clouds form, but is comparatively unusual near the surface where the air is generally warmer and laden with liquid and/or ice condensation nuclei. One exception is the surface of the
