Heart-shaped, with the petiole or stem attached to the notch cuneate: cuneatus: leaf base: Triangular, wedge-shaped, stem attaches to point cuneiform: whole leaf: Narrowly triangular, widest on the opposite end from the stem, with the corners at that end rounded cuspidate: cuspidatus: leaf tip: With a sharp, elongated, rigid tip; tipped with a cusp
Heart-shaped, with the notch lowermost; of the base of a leaf, like the notched part of a heart. Contrast obcordate. coriaceous Leathery; stiff and tough, but flexible. Compare corneous. corm. adj. cormose, cormous
[10] [11] It has peltate stipules which have an erose (irregularly notched) appendage below the point of attachment, 2—4mm in diameter. [6] These stipules have a lobe on one side only, are velvety in texture, broadly ovate in shape with the upper portion deltoid-ovate and ending in an acute tip, are (7-)10–13mm in length, (3-)5-6(-9)mm in ...
Acanthocytes, from peripheral blood, under light microscopy. Note the irregularly shaped, non-circular cells in the image. Acanthocyte (from the Greek word ἄκανθα acantha, meaning 'thorn'), in biology and medicine, refers to an abnormal form of red blood cell that has a spiked cell membrane, due to thorny projections.
The antegonial notch is a subtle indentation located on the inferior border of the mandible, immediately anterior to the angle of the mandible. It marks the transition between the inferior border of the mandibular body and the anterior border of the mandibular ramus .
In solid mechanics, a stress concentration (also called a stress raiser or a stress riser or notch sensitivity) is a location in an object where the stress is significantly greater than the surrounding region. Stress concentrations occur when there are irregularities in the geometry or material of a structural component that cause an ...
Bicycle frame in steel tube, notched at the joints before TIG welding or brazing. Tube notching is commonly performed before joining light-gauge tubes to make a tee or similar joint, as by welding. Either one or both tubes may be notched before assembly. A familiar example of tube notching is in the manufacture of bicycle frames.
For standardized testing of fracture toughness by the Charpy impact method, specimen and notch dimensions are most often taken from American standard ASTM E23, or British standard BS EN ISO 148-1:2009. For all notch types, a key parameter in governing stress concentration and failure in notched materials is the notch tip curvature or radius. [1]
