The protective layer of the epidermis in Drosophila (cuticle) and mice (stratum corneum) are structurally unrelated. Yet new evidence suggests a conserved transcription factor, Grainyhead, controls both their development and the means by which both structures repair themselves.

The article analyzes the operation of "engineering protective structures-soil massif" system in zone influence surrounding buildings presence complex engineering and geological conditions. Simulation task setting up a deep pit under protection with multi-tiered retaining wall was carried out. mutual development near new construction, depending on distance between them, revealed. optimal existin...

Ultra-thin diamond-like carbon (DLC) coatings are used in hard disk drives to protect the intricate magnetic structures from wear and corrosion. The coating on the recording head consists of a hard DLC layer and a silicon (Si) layer that improves adhesion between the DLC layer and the substrate. Damage to this protective coating can expose the magnetic structures to corrosion and compromise the...

nigella sativa (n. sativa), which belongs to the botanical family of ranunculaceae, is a widely used medicinal plant all over the world. n. sativa seeds and oil have been used in the treatment of different diseases. various studies on n. sativa have been carried out and a broad spectrum of its pharmacological actions have been established which include antioxidant, antidiabetic, anticancer, ant...
