They are sometimes regulated by forming artificial "joints" in the structure by embedding strips of wood or sheet iron at regular intervals, thus forming "lines of weakness," at which the cracks therefore take place.
A region where volcanic activity has led to the embedding of dykes or bosses of hard rock amongst softer strata produces a plain broken by abrupt and isolated eminences.'
A vase decorated with these simple or complex canes is produced by embedding short lengths of the cane on the surface of a mass of molten glass and blowing and fashioning the mass into the required shape.
The process of embedding gold and silver leaf between two layers of glass originated as early as the 1st century, probably in Alexandria.
The mucilage may also form an embedding substance similar to that of Chroococcaceae, in which the filaments lie parallel or radiate from a common centre (Rivulariaceae).
The immersion liquids in common use are water, glycerine, cedar-wood oil, monobromnaphthalene, &c. Immersion systems in which the embedding liquid, coverslip, immersion-liquid and front lens have equal refractive indices are called " homogeneous immersion systems."
The advantages of the immersion over the dry-systems are greatest when the embedding-liquid, the glass cover, the immersion-liquid and the front lens have the same refractive index.
Annually; and if that was the rate in Jacobs Cavern, 1968 years would have been needed for the embedding of that implement.
