Functional properties of mahaim fibers
Klinische Wochenschrift, 1977Electrophysiological studies were performed in a patient with a short P-R interval and a small delta wave. The findings suggest that ventricular pre-excitation resulted from an infranodal bypass (Mahaim type). As the functional properties of the pathway were evaluated, impaired conductivity (suggested by rather long refractory periods) became apparent ...

Fiber‐forming properties of polymer mixture melts and properties of fibers on their basis
Polymer Engineering & Science, 1999AbstractThe fiber‐forming properties of the following polymer mixture melts have been investigated: polypropylene‐copolyamide (PP/CPA), polyoxymethylene‐copolyamide (POM/CPA), POM‐copolymer of ethylene and vinyl acetate (POM/EVAC), PP/EVAC, EVAC/CPA, and polypropylene‐polyvinylalcohol (PP/PVA).

A sinusoidal rate of loading is one of the less common ways of testing fibers. A mathematical treatment of the behavior of visco-elastic materials under such conditions is developed, and this theory is applied to data obtained using Nylon 66 monofils. The results indicate that the sig nificant values for the flow process are dependent on the frequency ...

Journal of the Mechanics and Physics of Solids, 1994
Abstract The mechanical properties for carbon fibers are determined in terms of the elastic moduli of single crystal graphite. This is done for the two basic fiber microstructures, radial and onion skin. The final results are found through a transformation from cylindrically orthotropic to transversely isotropic properties.

Soviet Powder Metallurgy and Metal Ceramics, 1992
The content of the volume hydroxyl groups in the quartz fibers, produced by dispersion in a gas torch, increases with an increase of the specific surface of the specimen. The quartz fibers bond protons from slightly acidic solutions, and the degree of sorbtion of the protons, related to the unit surface of the fibers for different batches, is almost ...

Generally, electrospun nanofibers obtained on the collectors often existed in the form of nonwoven mats owing to the intrinsic instability. Although such nonwoven mats have gained tremendous focus in diverse applications including texturing, fiber reinforcement, tissue engineer, filter, sensing, and enzyme immobilization, the potential applications of ...

Microscopical Properties of Fibers
1994Fibers are unique units of biological tissues, mineral habits, or spinning processes; examples include muscle and nerve fibers, wool, fur, hair, cotton, linen, natural silk, natural and regenerated cellulose, asbestos, spun silicate glass, and man-made polymeric fibers.

Physicochemical Properties of Dietary Fiber
2001Gidley and colleagues have investigated the molecular structure of resistant starch in great detail using a combination of physicochemical techniques. Resistant starch behaves functionally as dietary fiber because it resists digestion by the enzymes of the stomach and small intestine. The physiological functions of dietary fiber change as it progresses

Optical Engineering, 1973
Investigations on UV-fibers (70 pm and 100 pm) consisting of a quartz core and a cladding of a fluorocarbon resin are discussed. The spectral distribution of the transmission is essentially given by that of the core material so that the light down to 200 nm can be transmitted at reasonable lengths. Above 300 nm the transmission values are comparable to
