Determining Cotton Fiber Maturity by Image Analysis
Textile Research Journal, 1994Image analysis presents a quick, reliable, unbiased technique for determining cotton fiber maturity. This research entails developing sampling techniques for cotton fiber cross sections and creating a computer program to measure fiber characteristics directly by image analysis.

Maturity and Dynamic Elastic Modulus of Cotton Fibers
Textile Research Journal, 1978The polarized-light method was used to select mature and immature individual fibers from each of four maturity standard cotton samples. The dynamic elastic modulus, or the sonic modulus, of the selected fibers was determined by the pulse-propagation method at different static strain levels, and continuous dynamic modulus-strain curves and dynamic ...

Maturation of nonmyelinated fiber bundles in a strain of dwarf (Snell's) Mice
The Anatomical Record, 1974AbstractPostnatal maturation of nonmyelinated fiber bundles (Schwann bundles) was studied in the sciatic nerves of Snell's dwarf mice. The homozygous recessive of this strain has been previously shown to be characterized by multiple pituitary hormone deficiencies and secondary hypothyroidism.In the normal littermates a reduction occurred between 10 and

The regenerative response of single mature muscle fibers isolated in vitro
Developmental Biology, 1975Abstract Segments of individual differentiated muscle fibers, ranging from 1–10 mm in length, were dissected from the pectoral muscle of juvenile Japanese quail and cultured for periods ranging up to 2–3 weeks under conditions known to promote the proliferation and eventual differentiation of embryonic myoblasts. Approximately 22% of such fibers give

[Maturation and aging of elastic fibers].
Zeitschrift fur Hautkrankheiten, 1990We give a review of the maturation and aging processes of elastic fibers. Elastic fibers of adult human skin are composed of elastin (amorphous matrix) and surrounded by microfibrils (structural glycoproteins). The physiological aging of elastic fibers is a continuous process starting at the age of 40 or 50 and reaching its final state in the senium ...

Never Dried Cotton Fibers as a Meaningful Expression of Maturity
Textile Research Journal, 1986A novel microscopical technique was used for direct measurement of the dimensions of never dried fibers, fibers swollen with water, and fibers swollen in sodium hydroxide. An extensive comparative study revealed that the original state of never dried fibers cannot be recovered when using seed cotton or bale cotton.

[Maturation and aging of elastic fibers (authors transl)].
Archives of dermatological research, 1978The non-sunexposed skin of 12 healthy individuals was investigated under the electron microscope and the fine structure of normal elastic fibers was compared by different methods in 3 groups of age: 1--10 years, 30--50 years, and 60 years. 1. The elastic fibers of human skin may be semiselectively stained with silver tetraphenylporphyrine sulfate (Ag ...

The Influence of Dietary Fiber Digestibility on the Nitrogen Requirements of Mature Horses
Journal of Animal Science, 1984Mature geldings at maintenance were fed different diets in a 4 x 4 Latin square design balanced to account for residual effects in an attempt to determine whether differences in the digestibility of the fibrous portions of feedstuffs would influence dietary nitrogen (N) requirements.

Identification of helical polyribosomes in sections of mature skeletal muscle fibers
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1971The localization and configurations of ribosomes in mature white skeletal muscle fibers of the rat were investigated. Differential visualization of ribosomes and glycogen granules was obtained by fixation with glutaraldehyde only and staining of the sections with uranyl acetate.
