(v. t.) To assume the mere appearance of, without the reality; to assume the signs or indications of, falsely; to counterfeit; to feign.
(1) It is concluded that during exposure to simulated microgravity early signs of osteoporosis occur in the tibial spongiosa and that changes in the spongy matter of tubular bones and vertebrae are similar and systemic.
(2) We present a mathematical model that is suitable to reconcile this apparent contradiction in the interpretation of the epidemiological data: the observed parallel time series for the spread of AIDS in groups with different risk of infection can be realized by computer simulation, if one assumes that the outbreak of full-blown AIDS only occurs if HIV and a certain infectious coagent (cofactor) CO are present.
(3) A Monte Carlo simulation was performed to characterize the spatial and energy distribution of bremsstrahlung radiation from beta point sources important to radioimmunotherapy (RIT).
(4) Angus (A), Charolais (C), Hereford (H), Limousin (L), and Simmental (S) breeds were included in deterministic computer models simulating integrated cow-calf-feedlot production systems.
(5) The design of a simple dynamic knee simulator is described.
(6) Our results suggest that during simulated ischemia the rate-dependent component of the increase in Ri contributes to the rate-dependence of the conduction slowing.
(7) The purposes of this study were to locate games and simulations available for nursing education, to categorize these materials to make them more accessible for nurse educators, and to determine how nursing's use of instructional games might be enhanced.
(8) It is intended to aid in finding the appropriate PI (proportional-integral) controller settings by means of computer simulation instead of real experiments with the system.
(9) The authors conclude that there is no heart rate-dependent signal loss in healthy persons that simulates valvular dysfunction, thus suggesting that signal intensity change can be used as an indicator for this disease, independent of heart rate.
(10) Dysplasia epiphysealis hemimelica - an epiphyseal developmental disturbance of the skeleton - is combined with exostose-like, tumor-simulating cartilaginous hypertrophy of bone tissue, mainly located at the epiphyses of the lower extremities and at the tarsal bones.
(11) Femoral angiograms were made in 21 cadavers under simulated clinical conditions, with a pressurized radiopaque casting material.
(12) A rubber cuff was fixed on the metal cylinder and let an opening of 8 cm, simulating the cervix uteri.
(13) It is suggested that this human model of unloading could serve to simulate effects of microgravity on skeletal muscle mass and function because reductions in muscle mass and strength were of similar magnitude to those produced by bed rest.
(14) To test this, a physiologic-based kinetic model was developed to simulate drug concentrations in brain and blood in the presence and absence of CNS metabolism.
(15) Echo delay discrimination by the bat Eptesicus fuscus had been investigated in an experiment with simulated targets jittering in range (Simmons 1979).
(16) Using the rate coefficient values found by SCoPfit, we simulated a voltage-clamp experiment with both models running under their Na(+)-Na+ exchange mode, and we computed the transient currents generated following voltage steps in both depolarizing and hyperpolarizing directions from a basic potential of -40 mV.
(17) By using increased feed-forward gain in a sampled-data control model we simulated the pattern of macrosaccadic oscillation.
(18) Studies on antimicrobial effect kinetics in dynamic models in vitro simulating pharmacokinetic profiles observed in humans markedly promote the problem solution.
(19) The technique was applied to the classification of MUAP's extracted from simulated myoelectric signals.
(20) The latter animals were raised in an automated feeding device (Autosow) with an artificial diet simulating the nutritional composition of sow milk.
