"Hemihedrism" Natural Recordings by Native Speakers
Hemihedrism is a term used in the field of geology to describe a type of crystal structure that has a repeating pattern of alternating right- and left-handed hexagonal rings. In other words, it refers to the arrangement of atoms or molecules in a crystal that displays a hemihedral symmetry, where the crystal appears to have a mirror symmetry about a single plane, but lacks a true mirror plane. This phenomenon is relatively rare and is often seen in certain minerals, such as oligoclase feldspar.
Hemihedrism
Definition: Hemihedrism refers to the quality or state of being partially or partially-edged, often referring to shapes or structures that are not perfectly symmetrical.
Examples:
Hemidomes refers to a type of architectural structure, specifically a church or temple with a hemispherical (half-spherical) dome as its primary design feature.
Hemidysplasia is a rare congenital disorder in which half of the body fails to develop properly due to a deficiency in the formation of bones, muscles, and other tissues. It is often associated with conditions such as cuts, wounds, or abnormal skin pigmentation on the affected side of the body.
Hemiectomy is a surgical procedure that involves the removal of half of the brain. It is most commonly performed on patients with severe and intractable epilepsy, where the hemispherectomy is used to reduce the frequency and intensity of seizures. The procedure can also be used to treat other conditions, such as childhood hemiplegia, a condition that affects the movement and development of one side of the body.
Hemigamous refers to a type of marriage in which one husband takes two or more wives, typically sisters, either simultaneously or consecutively. The term is often used to describe practices found in some indigenous cultures, particularly in South Asia, Africa, and the Pacific Islands.
Hemimandibulectomy is a surgical procedure in which half of the lower jawbone (mandible) is removed. It is typically performed to treat benign or malignant tumors, infections, or injuries that affect the mandible.
Hemimetabolic refers to the development of insects, including true bugs, grasshoppers, and cicadas, which undergo a series of molts (shedding of their skin) as they grow and mature, but do not undergo a complete transformation from a larval to adult stage, unlike holometabolic insects (such as bees, butterflies, and flies).
