muscle changes with eccentric exercise: implications on earth and in space

recent investigations of fluid pressure, morphology, and enzyme activities of skeletal muscle exercised eccentrically or concentrically in normal human subjects are reviewed. intramuscular pressures were measured before, during, and after submaximal exercise and correlated with subjective muscle soreness, fiber size, water content, and bl..

magnetic resonance of polymers at surfaces. technical rept

in most of the applications where polymers are used, more than one phase is present. in addition to the polymer matrix, the second phase may be comprised of the same or a different polymer, or of some type of filler or fiber which is typically a solid or solid-like. typical applications of these materials include use in: structural compos..

this bibliography contains citations of selected patents concerning electroless plating techniques used for materials deposition on polymer substrates. plating methods and compositions utilized in printed circuit device fabrication are discussed. plating solution preparations, and substrate surface treatment methods are included (this upd..

nicotinic cholinergic receptors in rat brain. final rept. 1 may 83-31 oct 86

nicotinic cholinergic receptors in rat brain were studied to determine their dependence on intact disulfide bonds, their relationship to catecholamine and serotonin axons, and their regulation by cholinesterase inhibitors and nicotinic agonists reduction of disulfide bonds with dithiothreitol decreased the number of nicotinic binding site..

effect of exercise training on skeletal muscle glucose transporter isoform glut4 concentration in the obese zucker rat. master's thesis

exercise training has been demonstrated to improve skeletal muscle insulin resistance, however, the mechanisms for this improvement have not been fully chararcterized. the effects of high (ht) and low (lt) intensity exercise training were therefore examined on insulin-stimulated 3-o-methyl-d-glucose (3-omg) transport and the concentration..

caracterisation de l'interface et de l'interphase dans les materiaux composites (characterization of composite interfaces and interphases) . final rept. dec 89-nov 90

three distinct families of composites were studied in order to structurally characterize their fiber-matrix interface and interphase. the first group consisted of xau/5245 (untreated fibers), xas/5245 (oxidized fibers), xau/eda/5245 and xau/teta/5245 (amine-treated fibers). the second group included im7/c59 and im7/isoh/c59 (oiled fibers)..

new anode materials for electrolytic persulfate formation. final rept. on phase 1

novel carbon-based electrode materials were prepared by a surface modification technique known as specific fluorination for use as anodes in the electrolytic production of persulfates. the specific fluorination process creates a stabilized form of carbon which is protected by fluorinating only the edge sites, grain boundaries, dislocation..

reexamination of metman, recommendations on enhancement of lcvg, and development of new concepts for emu heat sink. final report

metman is a 41-node transient metabolic computer code developed in 1970 and revised in 1989 by lockheed engineering and sciences, inc this program relies on a mathematical model to predict the transient temperature distribution in a body influenced by metabolic heat generation and thermal interaction with the environment. a more complex 3..

planar fiber-optic interferometer acoustic sensor. patent

a sensing portion for an interferometric acousto-optic sensor and a sensor using that sensing fiber are disclosed. the sensor fiber has an outer coating of a material having a low bulk modulus. this coating greatly enhances the sensitivity of the sensor fiber. in a preferred embodiment, the material of low bulk modulus embeds the sensor f..

receptor based fiber optic microsensor development. final rept. aug 88-aug 90

detection of chemicals and toxins in multi-component mixtures has previously required a knowledge of the identity of the species to be detected and expensive, time consuming analytical procedures. by focusing on the physiological targets (receptors, antibodies, and enzymes), which these agents attack, it is possible to have detection of c..
